Collection of umbilical cord blood and the risk of complications in postpartum women after natural labour in the context of the possibility of umbilical cord stem cells usage in clinical practice.

Ginekol Pol 2021 12;92(3):205-209. Epub 2021 Feb 12.

Collegium Medicum, Jan Kochanowski Univeristy, Kielce, Poland.

Objectives: Comparison of changes in peripheral blood venous morphology and the frequency of select complications in patients who underwent umbilical cord blood collection during the third stage of labour by in the utero method compared to patients who did not undergo this procedure. Presentation of current therapeutic possibilities of cord blood stem cells.

Material And Methods: The study involved 248 patients who had a vaginal delivery and had umbilical cord blood taken by in utero method during the third stage of labour. The control group consisted of the first 400 patients who gave vaginal delivery starting in 2019. Each patient had a venous peripheral blood count taken before delivery and 18 hours after delivery. Changes in the results of laboratory tests and the occurrence of adverse outcomes, such as postpartum curettage, postpartum haemorrhage and manual removal of placenta, in the 3rd and 4th stage delivery periods, were analysed.

Results: In the blood donor group there were significantly lower haemoglobin (11.32 g/L vs 11.61 g/L, p = 0.004) and haematocrit (32.83% vs 33.82% p = 0.001) concentrations after delivery. Umbilical cord donors had a greater difference in haemoglobin (postpartum minus prepartum) (-1.4 g/L vs -0.9 g/L, p = 000), and haematocrit (-4.05% vs -2.5% , p = 0.000). The study group had a higher percentage of patients with postpartum anaemia (haemoglobin concentration < 10 g/L) (15.9% vs 10.64%, p = 0.05), but the result were borderline significant. The groups did not differ in terms of the percentage of postpartum curettage, PPH, manual removal of placenta, percentage of severe anaemia (Hb < 7g/L) or transfusion requirement.

Conclusion: Collection of umbilical cord blood during the 3rd stage of labour using the in utero method is associated with a statistically significant increase of blood loss and a higher probability of postpartum anaemia. The observed changes are minor and may have little clinical significance in otherwise healthy patients.

The association between lymph node metastases and long-term survival in patients with epithelial ovarian cancer.

Contemp Oncol (Pozn) 2020 20;24(3):163-171. Epub 2020 Sep 20.

nd Department of Obstetrics and Gynaecology, Centre of Postgraduate Medical Education, Warsaw, Poland.

Introduction: A key survival prognosis factor for patients treated for ovarian cancer is complete cytoreductive surgery where all macroscopic neoplastic implants, including enlarged metastatic lymph nodes, are removed. We presume that investigating the involvement of the lymphatic system can result in a more individualized approach to the treatment of ovarian cancer patients. The main aim of our study was to analyze the relationship between the presence, number and types of lymph node metastases and ovarian cancer patient prognosis.

Material And Methods: We carried out a retrospective analysis of patients who underwent cytoreduction due to primary ovarian cancer, between 2010 and 2015. We analyzed the number of metastatic lymph nodes, the lymph node ratio defined as the ratio of the number of metastatic lymph nodes to the total number of lymph nodes removed, extracapsular involvement, and the histopathological pattern of metastases.

Results: The study group included 651 patients. Of these, 377 had lymphadenectomy, 144 presented with lymph node metastases, and 233 had no lymph node metastases. We also included a group of 274 patients who did not have lymphadenectomy. Patients with more than 4 metastatic lymph nodes and a lymph node ratio of ≥ 0.1 had significantly poorer overall survival. Extracapsular involvement had no relation to patient overall survival. Multivariant survival analysis indicated that a lymph node ratio of ≥ 0.1 was an independent predictor of poor survival.

Conclusions: The analysis of lymph node metastases in ovarian cancer patients can have predictive value for patient overall survival.

HPV genotyping and p16/Ki-67 test significantly improve detection rate of high-grade cervical squamous intraepithelial lesion.

Arch Med Sci 2020 11;16(1):87-93. Epub 2019 Jan 11.

Clinic of Gynecology, Holy-Cross Oncology Centre, Kielce, Poland.

Introduction: Liquid-based cytology allows to apply modern and specific analyses of hrHPV genotyping in p16/Ki-67 test. All of these together could raise accuracy ratio for high-grade squamous intraepithelial lesion above 90%. The purpose of this study was to evaluate the diagnostic accuracy of LBC, hrHPV testing, and p16/Ki-67 testing in diagnosis of high-grade cervical intraepithelial lesions.

Material And Methods: The study consisted of 176 women, out of which 50 presented with HSIL (CIN2) SCC (cervical intraepithelial lesion grade 2 squamous cell carcinoma). 126 women with a negative Pap test were pooled into the second group of the study. All patients were resampled for LBC, HPV genotyping, and for the p16/Ki-67 test. The research was carried out between May and December 2017, and second sampling were taken from 1 to 4 months.

Results: We reported a strong correlation between positive Pap test and hrHPV ( < 0.05) that met accuracy close to 90%. We noted correlations between a positive p16/Ki-67 with a positive Pap test: < 0.001; 66% sensitivity (95% CI: 51.2-78.8%), 87.8% specificity (95% CI: 75.2-95.4%), 76.8% accuracy (95% CI: 67.2-84.7%), and OR 13.9 (95% CI: 4.9-39.2), especially HSIL and HPV16: < 0.001; sensitivity (95% CI) 64.0, specificity (95% CI) 98.4, accuracy (95% CI) 88.6, OR (95% CI) 109.3.

Conclusions: The results of our study indicate hrHPV genotyping as a good biomarker for the triage of patients with an abnormal cytological report. In our opinion, the hrHPV test reaches the highest level of sensitivity, specificity, and accuracy, and should be considered as crucial diagnostic test in cervical screening.

Ginekol Pol 2020 ;91(1):13-16

Department and Clinic of Obstetrics and Gynaecology, Collegium Medicum Jan Kochanowski University in Kielce.

Objectives: Urinary incontinence (UI) can affect up to 50% of the population of women over the age of 50. In order to objectively assess discomfort in women with UI prior to initiating treatment and monitoring the outcomes of the treatment, validated questionnaires need to be used to examine the impact of UI on health-related quality of life (HR-QoL). The Urogenital Distress Inventory - Short Form (UDI-6) and the Medical Epidemiologic and Social Aspects of Ageing (MESA) questionnaires are used typically. Assessment of the Polish translation of the MESA and UDI-6 questionnaires.

Material And Methods: 155 patients with symptoms of UI were enrolled. Each of the patients completed the MESA and UDI questionnaires prior to being examined. The final diagnosis was made after diagnostic tests were carried out in the patients.

Results: Principle component analysis showed division of the Polish versions of the questionnaires into domains identical to the original version. Analyses of internal consistency reliability revealed high internal consistency for the MESA questionnaire (0.90) and a low reliability of the UDI-6 questionnaire (0.44).

Conclusions: The Polish version of the MESA questionnaire was demonstrated to be a clinically useful diagnostic tool in the studied population, UDI-6 did not reached a sufficiently high reliability in the study group to be recommended as a diagnostic tool.

Cerebral palsy and obstetric-neonatological interventions.

Ginekol Pol 2019 ;90(12):722-727

Department and Clinic of Obstetrics and Gynaecology, Collegium Medicum Jan Kochanowski University in Kielce.

Cerebral palsy is a disease that puts a great mental burden on caregivers and generates very high social costs. Children with CP require many years of rehabilitation and medical care. The etiology of the disease is undoubtedly multifactorial, and the pathogenesis is associated with focal damage to the central nervous system. One can find descriptions of well-documented interventions in the literature that reduce the risk of CP in certain groups of pregnant and neonatal patients, and interventions that have a potentially protective effect. In this review, we have analyzed the available literature in terms of prenatal and postnatal interventions that may have an impact on reducing the incidence of this condition in children.

Analysis of the treg cell population in the peripheral blood of ovarian cancer patients in relation to the long-term outcomes.

Ginekol Pol 2019 ;90(4):179-184

Chair of Oncology, Radiotherapy and Gynecologic-Oncology of the Ludwik Rydygier Medical College in Bydgoszcz, Nicolaus Copernicus University, Bydgoszcz, Poland.

Objectives: There is growing evidence that Treg cell infiltration into the cancer nest is associated with poor prognosis. How- ever, the Treg cell population in the peripheral blood may change when a different type of anticancer therapy is applied. Since Treg cells may support tumor growth by enhancing the suppressive profile of the cancer microenvironment, the assessment of Treg cells can bring to light important information regarding prognosis. Thus we decided to analyze the Treg cell population in the peripheral blood in relation to long-term outcomes in the group of patients with ovarian cancer.

Material And Methods: The 80 patients included in the study were treated surgically followed by chemiotherapy for ovar- ian cancer between October 2010 through May 2011.The peripheral blood samples from the patients were collected directly prior to chemotherapy. Information on any patients who died was retrieved from the database of the Cuiavia-Pomerania Regional Office of the National Health System of Poland. CD4+CD25+FOXP3+ lymphocytes T were assed by flow cytometry. We have analyzed the long term outcomes of treatment regarding to the level of Treg cells in peripheral blood.

Results: We found that patients with serous adenocarcinomas had significantly higher Treg levels compared to those patients with non-serous types. Patients who had a higher percentage of Treg cells within the CD4+ cell population prior to the beginning of the treatment had worse long-term outcomes from the applied therapy.

Conclusions: The assessment of Treg levels prior to the start of chemotherapy is clinically useful and may predict overall survival in ovarian cancer patients.

Factors associated with gestational weight gain: a cross-sectional survey.

BMC Pregnancy Childbirth 2018 Dec 3;18(1):465. Epub 2018 Dec 3.

Department of Surgery and Surgical Nursing with the Scientific Research Laboratory, Faculty of Medicine and Health Sciences, Jan Kochanowski University, Kielce, Poland.

Background: The aim of this study was to describe the dietary patterns in pregnant women and determine the association between diet factors, pre-pregnancy body mass index, socio-demographic characteristics and gestational weight gain.

Methods: The analysis was conducted on a group of 458 women. Cut-off values of gestational weight gain adequacy were based on recommendations published by the US Institute of Medicine and were body mass index-specific. Logistic regression analysis was used to assess the risk of the occurrence of inadequate or excessive gestational weight gain. Dietary patterns were identified by factor analysis.

Results: Three dietary patterns characteristic of pregnant women in Poland were identified: 'unhealthy', 'varied' and 'prudent'. The factor associated with increased risk of inadequate gestational weight gain was being underweight pre-pregnancy (OR = 2.61; p = 0.018). The factor associated with increased risk of excessive weight gain were being overweight or obese pre-pregnancy (OR = 7.00; p = 0.031) and quitting smoking (OR = 7.32; p = 0.019). The risk of excessive weight gain was decreased by being underweight pre-pregnancy (OR = 0.20; p = 0.041), being in the third or subsequent pregnancy compared to being in the first (OR = 0.37; p = 0.018), and having a high adherence to a prudent dietary pattern (OR = 0.47; p = 0.033).

Conclusions: Women who were overweight or obese pre-pregnancy and those who quit smoking at the beginning of pregnancy should be provided with dietary guidance to prevent excessive gestational weight gain.

Conservative treatment of abnormally located intrauterine pregnancies (cervical and cesarean scar pregnancies): a multicenter analysis (Polish series).

J Matern Fetal Neonatal Med 2020 Mar 20;33(6):993-998. Epub 2018 Sep 20.

Department of Fetal Medicine and Gynaecology, Medical University of Lodz, Lodz, Poland.

To analyze the effectiveness and outcome of conservative treatment in cases of abnormally located intrauterine pregnancies (cervical and cesarean scar). A retrospective analysis was performed of 30 pregnant women hospitalized due to abnormally located intrauterine pregnancies. The analyzed group comprised 24 pregnant women with abnormally located pregnancies. The patients were divided into two groups: the first group consisted of patients treated systemically with methotrexate, while the second of those treated locally by administration of methotrexate (MTX) and/or potassium chloride (KCl) by gestational sac puncture. The analyzed group comprised 24 pregnant women with abnormally located pregnancies. Eight patients were diagnosed with cervical pregnancy (CP) and 16 patients were diagnosed with cesarean scar pregnancy (CSP). Six patients were excluded from the study: two with spontaneous abortions, two heterotopic pregnancies, and two cornual pregnancies. Twelve analyzed patients underwent MTX systemic administration (five patients with CP, seven with CSP). In five patients, systemic treatment was ineffective; they were qualified for additional local therapy with gestational sac (GS) puncture and MTX or KCl administration to the sac and additional administration of MTX to the trophoblast area. In second group of 12 patients (three CP, nine CSP), local treatment (GS puncture with MTX or MTX + KCl) was used as the first line treatment. One patient underwent combined treatment (local + systemic). Conservative treatment should be the gold standard procedure in abnormally located intrauterine pregnancies. It is noticeable that MTX / KCl is more effective in a direct administration to the GS. In four cases, systemic MTX did not produce the desired effects. In these cases, the treatment was assisted by local administration of MTX or KCl, resulting in the termination of an abnormally located pregnancy.

Diastasis recti abdominis - a review of treatment methods.

Ginekol Pol 2018 ;89(2):97-101

Institute of Physiotherapy, Jan Kochanowski University in Kielce, Kielce, Poland.

Diastasis recti abdominis is a condition in which both rectus abdominis muscles disintegrate to the sides, this being ac-companied by the extension of the linea alba tissue and bulging of the abdominal wall. DRA may result in the herniation of the abdominal viscera, but it is not a hernia per se. DRA is common in the female population during pregnancy and in the postpartum period. There is a scant knowledge on the prevalence, risk factors, prevention or management of the abovemen-tioned condition. The aim of this paper is to present the methods of DRA treatment based on the results of recent studies.

Ten years of anti-HPV vaccinations: what do we know?

Prz Menopauzalny 2016 Nov 15;15(3):170-175. Epub 2016 Nov 15.

Department of Gynecology and Obstetrics SP ZOZ in Myślenice, Poland.

Human papillomavirus (HPV) is one of the most important carcinogens in humans. Vaccines against HPV are now considered the first anti-cancer vaccinations. Since 2007, in many developed countries, there have been recommendations present for preventive vaccines against HPV. At present, the degree of implementation of these recommendations depends on a number of country-specific factors such as the health care system organization or the ways of funding. HPV vaccines are primarily to prevent the development of cervical cancer and other genital cancers. Therefore, only their long-term effectiveness can be measured, when a correspondingly large cohort of vaccinated teenagers reaches the age of the greatest incidence of these cancers. However, great care should be taken in assessing the results of vaccinations due to the possibility of misinterpretation and possible erroneous data. Undoubtedly, teenagers are the target population of HPV vaccines. However, vaccinating young sexually active women is also justified from an individual point of view. A 9-valent vaccine has been registered in the USA and in Europe - including Poland - as one of the three preventive vaccines. It is recommended to vaccinate women between 13 and 26 and men between 13 and 21, previously unvaccinated. It is also recommended to vaccinate men aged 26 years or less who have sexual relations with other men and people with reduced immunity, including HIV-positive people who have not been vaccinated previously.

Comparison of the effectiveness of cytodiagnostics, molecular identification of HPV HR and CINtecPLUS test to identify LG SIL and HG SIL.

Ginekol Pol 2012 Dec;83(12):894-8

Department of Gynecology and Obstetrics Hospital, NZOZ of St. Alexandra, Kielce, Poland.

Aim Of The Paper: Comparison of conventional cytodiagnostics with molecular identification of DNA and mRNA HPV HR, immunocytochemical test for suppressor protein P16 and nuclear Ki 67 to detect cervical pathology screening of the division to LG SIL and HG SIL.

Material: 630 Pap smears were taken from women with suspected cervical pathology were submitted for analysis, together with 558 smears for the presence of DNA HPV HR, 421 swabs for the presence of mRNA HPV HR, 86 swabs for the presence of suppressor protein P16 and nuclear Ki 67. In all of the women standard colposcopy with biopsy and endocervical abrasion were performed.

Method: The study used a classic cytological smear taken on the slide, rated in accordance with TBS classification, colposcopy implemented in accordance with the guidelines of the International Federation of Cervical Pathology and Colposcopy from 2003, molecular diagnostic tests based on identifying DNA, mRNA HPV HR and immunocytochemistry diagnostic test--CINtecPLUS.

Results: The sensitivity of Pap test identification of CIN 2+ was of 85% and specificity of 23%. Indicators PPV and NPV were respectively 39% and 72%. The accuracy of cytology reached a level of 46%. DNA HPV HR test obtained 91% sensitivity and 33% specificity of the diagnosis of CIN 2+. Its accuracy was 54%. The value of PPV and NPV for molecular diagnostics was respectively 43% and 87%. For mRNA HPV HR test sensitivity of the method was 79%, the specificity was 67%. CINTecPLUS test achieved 100% sensitivity and 67% specificity in the diagnosis of CIN 2+.

Conclusions: 1. Conventional cytodiagnostics are inferior in terms of both sensitivity and specificity of molecular test for DNA, mRNA HPV HR and immunocytochemical test for detecting of LG SIL and HG SIL. 2. Immunocytochemical technique shows maximum sensitivity and high specificity of detection of actual precancerous stages--CIN 2+.

[Results of pap smears and immunocytochemical detection of the p16 and Ki67 proteins in women with cervical intraepithelial neoplasia and cervical cancer].

Ginekol Pol 2012 Nov;83(11):822-6

Wydział Nauk o Zdrowiu Uniwersytet Jana Kochanowskiego w Kielcach, Polska.

Objective: The aim of the study was to assess the diagnostic value of pap smears and detection of the p16 and Ki67 proteins in women with cervical intraepithelial neoplasia (CIN).

Materials And Method: 630 women, aged between 25 and 65, with abnormal pap smears were included into the study All patients had a control pap smear and in each case punch biopsy with endocervical curettage were performed under the control of a colposcope. The presence of p16 and Ki67 proteins was detected using the CINtecPlus test. The results of the research were statistically assessed.

Results: Abnormal pap smears were found in 82.5% (520/630) of the studied women. In 40% (252/630) of the cases the LSIL changes were found. The recognition of ASC-US concerned 35.2% (222/630) of the patients, and pap smears with the HSIL result were found in 7.3% (46/630) of the women. In 17.5% (110/630) of the patients the result of the cytological examination was normal. Abnormal results of the pap smears were found significantly statistically more frequently (p<0,0001) in women with cervical intraepithelial neoplasia (CIN). The results of the CINtecPlus test were positive in 68,4% of women with CIN and in 33,3% of patients with normal cervix. In the group of women with precancerous lesions (HGSIL/CIN2+) the diagnostic accuracy of the pap smear was 41% for the cytological results ASC-US, 56% LSIL and 73% for detection of HSIL. Immunocytochemical detection of p16 and Ki67 proteins gained the highest accuracy (78%) in recognition of cervical precancerous lesions.

Conclusion: 1. ASC-US and LSIL cytological recognition has low accuracy in the diagnosis of CIN2+ cervical changes. 2. Cytological recognition of HSIL has the highest accuracy in the diagnosis of CIN2+ changes. 3. Immunocytochemical detection of p16 and Ki67 proteins is more accurate in recognizing precancerous states and cervical cancer than cytological examination. 4. Immunocytochemical detection of the p16 and Ki67 proteins can be used to triage patients with atypical squamous cells of undetermined significance and low grade squamous intraepithelial lesions.

[Risk assessment of chronic HPV HR infection in babies who contacted the virus in the perinatal period].

Ginekol Pol 2011 Sep;82(9):664-9

Wydział Nauk o Zdrowiu, Uniwersytet Medyczny w Poznaniu, Polska.

Introduction: One of the potential ways of HPV transmission to fetuses and newborns is a direct perinatal infection, manifested as juvenile laryngeal papillomatosis (JLP). This applies to children after traditional birth, born to mothers in whom the DNA sequences of the HPV HR in the paraepidermal epithelium of cervix were found during pregnancy and delivery

Objectives: Risk assessment of the development of chronic HPV HR infection in babies who had contact with the virus in the perinatal period.

Materials And Methods: During the pre- and perinatal period, research was carried out among 185 pregnant women and a group of 105 newborns (5 pairs of twins), hospitalized in the Delivery Room of the Gynecology and Obstetrics Clinic of the Poznań Medical University between 2005-2007. Cellular material from the uterine cervical canal using a brush-type Cervex Brush was collected from each woman participating in the study and oral swabs using swab sticks were taken from the newborns. The second phase of testing was conducted following the postpartum, 3 to 6 months after the delivery Uterine cervix swabs were re-collected from 28 HPV HR positive women and swab from the mouth and nasopharynx were taken from their children (29 samples--1 pair of twins). The study was conducted with the use of PCR, trade named AMPLICOR Human Papilloma Virus (HPV) Test by Roche.

Results: DNA HPV HR was found in 55 cases of the cellular material derived from 185 swabs taken from the cervical canal, representing 29.7% of researched women. The chronic HPV HR viral infection was detected in 25 cases out of the 28 HPV HR positive women, representing 89.2% of the study group. Of the 105 infants from whom oral swabs were taken in the perinatal period, presence of DNA HPV HR was found in 2 infants (2%) after traditional birth. Whereas the repeated test, within 3-6 months after delivery revealed the presence of DNA HPV HR viruses in swab oral in 1 infant, who had been DNA HPV HR positive.

Conclusions: Perinatal transmission of Human Papillomavirus of the high-risk oncogenic type is rare and concerns below 2% of babies of HPV HR positive mothers. Prolonged infection by the Human Papillomavirus is an extremely rare complication of pregnancy and delivery and concerns below 1% of children of HPV HR positive mothers. Perinatal transmission of the oncogenic type infection of the virus in humans is primarily of the ascending type or occurs during the perinatal period if the delivery was a traditional one.

Authors:
Rokita Wojciech

Ginekol Pol 2011 Aug;82(8):618-22

Department of Obstetrics and Gynecology St Alexander City Hospital, Kielce, Poland.

Cryosurgery is a destructive technique that was introduced to gynecology in the late 1960s to treat C/N (cervical intraepithelial neoplasia). Tens of thousands of patients have been treated with cryotherapy which has proved to be a predictable, reliable treatment technique, with limited side effects and morbidity. This method is used to treat cervical, vaginal, endometrial and vulvar lesions. This study aims at determining the current state of knowledge on the place of cryosurgery (cryotherapy) in gynecological practice. Research was carried out to find current data on indications, contraindications, techniques of treatment and equipment necessary to perform cryosurgical procedures in gynecology. Cryosurgery is a safe, relatively inexpensive and easy to perform procedure for treating women with lower genital tract pre-malignant diseases without impairing their fertility.

Analysis of Treg cell population alterations in the peripheral blood of patients treated surgically for ovarian cancer - a preliminary report.

Am J Reprod Immunol 2011 Nov 30;66(5):444-50. Epub 2011 May 30.

Department of Gynecology and Oncology, Lukaszczyk Oncological Center, Bydgoszcz, Poland.

Problem: Treg cells constitute the main cell population that enables cancer cells to evade immune surveillance. An alteration in the Treg cell population might correspond to the diminishment of the tumour mass in patients with cancer and could therefore be a useful marker of the intensity of the selective suppression of the host immune system and also of the degree of radicalism of a procedure. Certainly, it is well known that in order for anti-cancer therapy to succeed the proper immune response against cancer cells must be restored. Furthermore, monitoring the level of selective immune system suppression during cancer therapy might yield information that would support a decision to supplement standard therapy by immunotherapy or to increase the degree of radicalism of the applied therapy.

Method Of Study: We examined the Treg cell populations in the peripheral blood of a group of patients treated surgically for ovarian cancer. In each patient, the peripheral blood samples were collected both prior to and 1 day after the surgical procedure, and then again 5 days after the procedure. The presence of regulatory T cells in the samples was analyzed by means of flow cytometry.

Results: In our study, the percentages of FOXP3(+) cells in the subpopulation of CD4(+) T lymphocytes found in the peripheral blood of the patients before the surgical intervention were statistically significantly higher than those observed in the peripheral blood of these same patients after the surgical procedure.

Conclusion: It would seem that the alteration in the Treg cell subpopulation could be a key factor in determining the status of the tumour microenvironment. Most likely, it could provide information about whether the proper level of anti-cancer immune response could be restored. The possibility of restoring the immune response may directly correspond to the degree of radicalism of the surgical intervention.

[Economic aspects of using selected biomarkers in cervical cancer screening].

Ginekol Pol 2010 Oct;81(10):774-7

Oddział Połoinictwa i Ginekologii Szpital Kielecki NZOZ Sw. Aleksandra, Kielce.

Increasing knowledge about the cervical cancer etiology, combined with the development of molecular diagnostics technology using DNA matrix and mRNA matrix, introduced a new quality in cervical cancer screening. Moving the diagnostics from the cellular level into the molecular level allowed not only to identify the existing precancerous states, but also to foresee these pathologies in the stage of cellular or molecular changes using oncogenesis biomarkers. The new diagnostic tools give hope for the improvement of effectiveness of cervical cancer screening and for a significant reduction of costs.

Background: Screening programs may contribute to decreasing the mortality rate in a given population and their main target, in case of cervical cancer; is to find and to cure preclinical stages of this malignancy. Regularly repeated tests in defined time intervals can diagnose the illness at its early stages but the results come with a high cost. Population program of early detection of cervical cancer has been conducted since 2007 and is run by the Central Coordinating Center and 16 regional centers. Funds for promotional, educational, monitoring and medical activities are obtained from the National Health Service.

Aim: The aim of this study was to present the cost-effectiveness of the Program between 2007 and 2009.

Material And Methods: The material for the analysis was obtained from the SIMP system, where all the data about women participating in the Program are implemented. The analysis of the cervical carcinoma treatment and procedure costs was made on the basis of the National Health Service estimates. The number of new cervical carcinoma cases was calculated with the help of the newly introduced system code--C53.

Results: Between 2007 and 2009 the cost of one cytological smear was similar in all regions (about 10 PLN). The highest costs were noted in Lubuski and Swietokrzyski regions. The costs of promotional and educational activities amounted up to 4.5 million PLN. A single cervical smear test cost for one woman has increased in the analyzed years from 3.95 up to 7.34 PLN. The total cost of one woman cytological examination--medical and non-medical elements--was more than 60 PLN. In 2009, 622 new cases of cervical cancer were found thanks to the Program. The cost of one case of cervical cancer diagnosis was 15 000 PLN. The total costs of all cases of cervical cancer in 2009 was 45.5 million PLN.

Conclusions: The situation calls for creating new and effective tools for monitoring medical, epidemiological and financial parameters of the Program. Otherwise, the estimates of the health and social impact of the Program will fail to be plausible. Increased attendance at the Program will only marginally lower the costs of the tests. Not to mention, that different means and solutions regarding cervical cancer prevention need to be suggested due to the fact that Polish population does not yet seem to have developed the habit of taking preventive tests.

[Genotyping of oncogenic human papilloma viruses in women with HG SIL diagnosis].

Ginekol Pol 2010 Oct;81(10):740-4

Klinika Onkologii Ginekologicznej UM im. Karola Marcinkowskiego w Poznaniu.

Introduction: Development of primary prevention of cervical cancer in other words a vaccination against selected, oncogenic HPV types, entails an increasing importance of epidemiological studies and prevalence of various types of human papilloma virus. The incidence of HPV varies depending on the geographic location of the population. The effectiveness of primary prevention against HPV 16, 18, in the context of reducing the incidence of cervical cancer will depend, among others, on the prevalence of these types in the population and virus-like antigens, which are partially cross-resistant.

Objective: Identification of the most frequent, oncogenic HPV types in women with HG SIL diagnosis from Central and Western Poland to assess the merits of the development of primary prevention.

Material: For the purpose of molecular tests identifying the presence of 13 DNA oncogenic virus types, swabs were taken with the cyto-brush from 76 women diagnosed with CIN 2 or CIN 3 (HG SIL). Patients eligible for the study were diagnosed at the Laboratory of Pathophysiology of Uterine Cervix, Gynecology and Obstetrics Clinical Hospital of Karol Marcinkowski University of Medical Sciences. Patients came from Central and Western parts of Poland.

Method: Cell material in which the method of Amplicor HPV (Roche Diagnostics) identified the presence of DNA of oncogenic HPV types was in each case subsequently subjected to genotyping using the molecular test - Linear Array HPV Genotyping (Roche Diagnostics).

Results: Five most common oncogenic HPV types in order of detection included: 16, 33, 18, 31, 56. Together these five types of virus comprised 75.86% (88/116) of all detected HPV types.

Conclusions: 1. In women from Central and Western Poland, diagnosed with HG SIL, the most common HPV genotypes were HPV 16, HPV33, HPV 18, HPV31, HPV56. 2. Two HPV types 16 and 18, against which vaccinations are directed, belong to the group of three genotypes of HPV most commonly identified in the evolution of CIN 2, CIN 3 diagnosed in women from Central and Western Poland.

[Human papilloma virus genotyping in women with CIN 1].

Ginekol Pol 2010 Sep;81(9):664-7

Klinika Onkologii Ginekologicznej UM im. Karola Marcinkowskiego w Poznaniu.

Introduction: Cervical cancer remains a considerable diagnostic and therapeutic problem in Poland. Despite progress in creating an active cancer prevention program in our country Poland occupies one of the last places in the EU in terms of cervical cancer- morbidity and mortality Supplement of secondary prevention of primary prophylaxis-HPV 16, 18 vaccination, offers hope for improvement of the situation. Epidemiology of individual HPV types differs, depending on the geographical location of the study population. So far in Poland, we have had no reliable data on the participation of selected oncogenic HPV types in the development of cervical pathology

Objective: Identification of the most frequent, oncogenic HPV types in women diagnosed with CIN 1, from the Central and Western Poland.

Material: In the course of the conducted studies, genotyping of 13 types of human papilloma virus has been done in 126 HPV DNA-positive women diagnosed with CIN 1.

Method: Each cell material in which the presence of HPVDNA identified 13 types of oncogenic human papillomavirus was subsequently subjected to genotyping using the molecular test--Linear Array HPV Genotyping (Roche Diagnostics).

Results And Conclusion: In women from the Central and Western Poland diagnosed with CIN 1, HPV 16 (53.97%) was the most common, followed by HPV 33 (21.3%), HPV 18 (16.67%), HPV 31 (10.32%), HPV 45 (7.94%), HPV 52 (1.59%). Current HPV vaccines are designed to protect against two of the three most common genotypes, in women diagnosed with CIN 1 in Central and Western Poland.

[Attendance rate in the Polish Cervical Cancer Screening Program in the years 2007-2009].

Ginekol Pol 2010 Sep;81(9):655-63

Klinika Onkologii Ginekologicznej Uniwersytetu Medycznego w Poznaniu.

Background: In Poland in 2007, according to the National Cancer Registry 3431 women were diagnosed with cervical cancer and 1907 died. To change the unfavorable epidemiologic situation, in 2005 the Ministry of Health (MH), the National Health Fund (NHF) and the Polish Gynecological Society following WHO/IARC guidelines developed a National Population-Based Cervical Cancer Screening Program. Its implementation and roll-out started in 2006. The target population are women aged 25 to 59 insured in the National Health Fund. A Pap test is done with a three-year interval, free of charge. The system is based on personal invitations sent by regular post. Invitation to screening is supported by a social educational campaign "Choose Life" run under one slogan and logo across the whole country The NHF data base enables identification of women to screen. Pap smears are collected by gynecologists and since 2008 also by midwives trained and certified by the Program National Coordinating Center Pap test results are reported in the Bethesda 2001 system. The Screening Program has its system of quality assurance and control and is supported by a specially designed computer data base called SIMP (System of Information Monitoring in Prophylaxis) with online access to all records. In addition to organized, population-based screening there is also opportunistic screening in Poland practiced either by private gynecological practices or by some units that cooperate with the National Health Fund, but do Pap tests as an element of comprehensive gynecological examination. Those smears are not registered in the SIMP.

Aim: Our aim was analysis of attendance rate in the Cervical Cancer Screening Program in the years 2007-2009. We also investigated correlation between screening coverage and invitation sending schedule, as well as between coverage and screening accessibility determined by the number of gynaecological practices where Pap smears are collected.

Material And Methods: Attendance rate in the Screening Program was evaluated for the years 2007, 2008 and 2009. The analysis included screening coverage in all voivodeships in the 12 months of the year as well as the number of gynaecological practices participating in the Program. In addition, the place of residence of screening attenders (urban/rural area) was taken into account. For the analysis the SIMP (System of Information Monitoring in Prophylaxis) data were used. Statistical analysis was performed using Statistica 9.0 software. P-values < 0.05 were considered statistically significant.

Results: The target population in the years 2007-2009 was 9,727,842 women. Personal invitations were sent to 99.7% of them. Pap Smears were collected from 24.14% of the target women (in 2007--21.25%; in 2008--24.39%; in 2009--26.77%). We noted that the number of 1400 gynecological practices participating in the Program was the minimal value to observe a significant increase in the number of Pap smears collected (p = 0.000). Polish women do not attend screening in the winter months. However when a batch of invitations was sent in the spring or summer months, within two following months we could observe an increase in the number of Pap smears collected (p = 0.000). There are significant differences in the screening uptake in particular regions of Poland (a stable trend). Compared to urban women, rural women participate in the screening more often (p = 0.003).

Conclusion: All Pap test results including opportunistic screening should be registered in the SIMP In the regions where particularly low attendance rates were observed, an intensive promotional campaign should be run to encourage participation in the screening. Also, sending a repeated invitation to non-compliers should be considered. The currently unfavorable schedule of invitation sending should be changed. According to the analysis performed, invitations should be more effective if sent on a regular basis (in small but regular batches), more intensively in the summer and spring months. In the winter season it would probably be better to focus on an extensive media campaign followed by sending a large number of personal invitations.

[Electrosurgery of cervical changes and its place in cervical cancer prophylaxis].

Ginekol Pol 2009 Nov;80(11):856-60

Oddział Połoznictwa i Ginekologii Szpital Kielecki NZOZ Sw. Aleksandra, Kielce.

For many years electrosurgical procedures have been used to treat cervical changes. The equipment and the technique of performing these procedures have evolved considerably during the recent years. The Fisher cone and electrocoagulation of the cervix have been replaced with the LLETZ/LEEP procedure. Low cost, the simplicity of performance, high safety and high therapeutic effectiveness in treating precancerous cervical changes make the LLETZ/LEEP procedure a very good method of accomplishing the cervical cancer preventive program. The indications, contra-indications, the technique of performance along with postoperative complications after the LLETZ/LEEP procedure and the physical basics of electrosurgical procedures were thoroughly presented in the article.

[Ectopic pregnancy rupture--can it be prevented?].

Ginekol Pol 2009 Oct;80(10):734-9

Klinika Ginekologii i Onkologii Uniwersytetu Jagiellońskiego w Krakowie.

Objectives: To determine risk factors for ectopic pregnancy (EP) rupture based on the patients history and preoperative tests.

Materials And Methods: The retrospective study consisted of 175 women operated on due to EP in the Department of Gynecology and Oncology of the Jagiellonian University between 2000-2008. Tubal rupture was diagnosed at the time of surgery. The patients were then divided into three groups: those who had unruptured EP without bleeding, those who had unruptured EP with hemorrhage into peritoneal cavity and those who suffered ruptured tubal pregnancy Analysis was performed based on the following parameters: patient history preoperative laboratory tests (Hb, Hct, betaHCG), and ultrasound exam.

Results: Of the 175 cases of ectopic pregnancy included in the study 20% were unruptured without bleeding (A) and 40.6% unruptured with hemorrhage (B) while 39.4% were ruptured (C). There was a positive correlation between the diameter of the tubal lesion measured ultrasonographically and rupture (37.4 +/- 16 for C vs 29.7 +/- 12.9 for A; p=0.04). The gestational age of the groups differed significantly (p=0,001): C (56 +/- 1), A (49 +/- 3), and B (42 +/- 2). There was also a positive correlation between rupture and gravidity (1 +/- 1 for A vs 2 +/- 2 for C; p=0.02). Moreover a positive correlation of borderline significance was discerned between rupture and parity (p=0.06). Additionally the preoperative hemoglobin and hematocrit values were significantly lower in the rupture group (p=0.001). There was no significant difference among the three groups in age, number of abortions, serum betaHCG, endometrial thickness, length of hospital stay or the time elapsed since the most recent pregnancy.

Conclusions: Low hemoglobin and hematocrit values, together with higher gravidity at the time of admission, may indicate an increased risk of tubal rupture.

Analysis of hMLH1 and hMSH2 expression in cisplatin-treated ovarian cancer patients.

Ginekol Pol 2008 Dec;79(12):826-34

Department of Gynecology, Obstetrics and Gynecologic Oncology, Division of Gynecologic Oncology, Poznan University of Medical Sciences, Polna.

Background: Loss of DNA mismatch repair may result in resistance to platinum- based anticancer drugs. The hMLH1 and hMSH2 proteins play a critical role in the maintenance of genome integrity and are involved in resistance to platinum-based therapy in colorectal cancer, which is deficient in hMLH1 protein and endometrial cancer, as well as in hMSH2 protein. However, the predictive value of MLH1 and MSH2 expression in ovarian cancer cisplatin-resistance is still to be determined.

Objective: The aim of this study was to investigate the expression of hMLH1 and hMSH2 proteins in ovarian carcinoma specimens and to evaluate their prognostic significance by means of overall survival (OS) and progression-free survival rates (PSF).

Material: Ovarian cancer tissues were obtained from 61 patients: 45 platinum-sensitive and 16 platinum-resistant. hMLH1 and hMSH2 proteins expression was evaluated by immunohistochemistry, with the use of mouse monoclonal antibodies clone 14 for hMLH1 and clone FE11 for hMSH2. The log-rank test and Kaplan-Meier statistics were used to analyze the relationship between proteins expression and progression free survival, as well as the overall survival.

Result: No significant correlation was found between hMLH1 and hMSH2 expression and overall survival and progression free survival in the group of patients sensitive and resistant to cisplatin. No significant difference was found in proteins expression intensity between the two compared groups of patients. Age of patients, type of cancer histology, FIGO staging, grading, clinical response and CA 125 did not reveal correlation with the expression of the analyzed proteins.

Conclusion: The immunohistochemical expression of hMLH1 and hMSH2 proteins in ovarian cancer has no predictive value in resistance to cisplatin.

[The diagnostic value of chosen questionnaires (UDI 6SF, Gaudenz, MESA, ICIQ-SF and King's Health Questionnaire) in diagnosis of different types of women's urinary incontinence].

Ginekol Pol 2008 May;79(5):338-41

Oddział Urologiczny Szpital im. Sw. Rafała Wojewódzki Specjalistyczny Zespół Opieki Zdrowotnej Gruźlicy i Chorób Płuc w Kielcach.

The Aim: The assessment of the usefulness of the following questionnaires: UDI 6SF, King's Health Questionnaire, Gaudenz, MESA, ICIQ-SF in diagnosis of different types of women's urinary incontinence.

Material And Methods: The study included 100 women who were hospitalized in the Department of Urology of St. Rafael Hospital in Czerwona Góra due to urinary incontinence. On the basis of the received data we have compared the data from questionnairies to the results of the urodynamic study.

Results: The mean age of women was 55.6 years. The stress urinary incontinence (SUI) was diagnosed in 32%, urgent urinary incontinence (UUI) in 10% and mixed urinary incontinence (MUI) in 55% of women, and neurogenic bladder in 3%. The data obtained from the study showed that questionnaires had 98% sensitivity and 50% specificity in diagnosing the type of urinary incontinence in women.

Conclusions: 1. Data obtained from the questionnaires fails to offer enough information to make a certain diagnosis of urinary incontinence. 2. The questionnaires: ICIQ-SF, Gaudenz and MESA are effective in the diagnosis of mixed urinary incontinence. 3. In spite of their high sensitivity, the specificity of questionnaires in the diagnosis of urinary incontinence is rather low.
