BACKGROUND Contrast-enhanced spectral mammography (CESM) is digital mammography with contrast agent. This promising new breast imaging method can be used for planning surgical treatment. This study compared CESM versus digital mammography (MG) in evaluating tumor size in breast cancer. MATERIAL AND METHODS Comparison of tumor dimensions in CESM, MG, and histopathology was made. The correlation of these data was assessed by histopathological type, biological subtype, grading of the carcinoma, and patient age. RESULTS The average difference in tumor size between CESM and histopathological examination was 5 mm. The differences in size measurement between CESM and MG were significant (p=0.00). The Pearson's linear correlation coefficients of CESM versus HP and MG versus HP were -0.01 (p=0.79) and -0.25 (p=0.00), respectively, indicating no differences between CESM and HP based on the lesion size. A weak negative correlation between those values was observed on MG. No relationship was found between the tumor size in CESM and the biological subtype, carcinoma malignancy degree, or patient age. CONCLUSIONS CESM is a new diagnostic method in breast cancer. The accuracy of measurement of tumor size using CESM is independent of lesion size, but it overestimates the size by 5 mm on average. The difference is not dependent on grading, biological subtype of the carcinoma, or patient age. They concern the histopathological type, and values are significantly greater in pre‑invasive carcinomas.

Progress in the diagnostics and therapy of gastro-entero-pancreatic (GEP) neuroendocrine neoplasms (NEN), the published results of new randomised clinical trials, and the new guidelines issued by the European Neuroendocrine Tumour Society (ENETS) have led the Polish Network of Neuroendocrine Tumours to update the 2013 guidelines regarding management of these neoplasms. We present the general recommendations for the management of NENs, developed by experts during the Third Round Table Conference - Diagnostics and therapy of gastro-entero-pancreatic neuroendocrine neoplasms: Polish recommendations in view of current European recommenda-tions, which took place in December 2016 in Żelechów near Warsaw. Drawing from the extensive experience of centres dealing with this type of neoplasms, we hope that we have managed to develop the optimal management system, applying the most recent achievements in the field of medicine, for these patients, and that it can be implemented effectively in Poland. These management guidelines have been arranged in the following order: gastric and duodenal NENs (including gastrinoma); pancreatic NENs; NENs of the small intestine and appendix, and colorectal NENs.

Colorectal neuroendocrine neoplasms - management guidelines (recommended by the Polish Network of Neuroendocrine Tumours).

Endokrynol Pol 2017 ;68(2):250-260

Neuroendocrine neoplasms/tumours (NENs/NETs) of the large intestine are detected increasingly often, especially rectal tumours, which is probably associated with the widespread use of screening colonoscopy. There is a growing body of evidence supporting the thesis that the NENs of the rectum and the NENs of the colon are two different diseases. Rectal NENs are usually small lesions, of low to moderate histological malignancy, associated with good prognosis, and most may be treated endoscopically. NENs of the colon, however, are often aggressive, poorly differentiated, associated with a poor or uncer-tain prognosis, and require surgical treatment. The management guidelines regarding these groups of patients are constantly changing. On the basis of the recent literature data and conclusions reached by the working meeting of the Polish Network of Neuroendocrine Tumours (December 2016), this study completes and updates the data and management guidelines regarding colorectal NENs published in Endokrynologia Polska 2013; 64: 358-368.

Neuroendocrine neoplasms of the small intestine and appendix - management guidelines (recommended by the Polish Network of Neuroendocrine Tumours).

Endokrynol Pol 2017 ;68(2):223-236

This study presents the revised Polish guidelines regarding the management of patients suffering from neuroendocrine neoplasms (NENs) of the small intestine and appendix. The small intestine, especially the ileum, is the most common location for these neoplasms. Most are well differentiated and slow growing. Their symptoms may be atypical, which can result in delayed or accidental diagnosis. Appendicitis is usually the first manifestation of NEN in this location. Typical symptoms of carcinoid syndrome occur in approximately 20-30% of patients suffering from small intestinal NENs with distant metastases. The main cause of death in patients with carcinoid syndrome is carcinoid heart disease. The most useful laboratory test is the determination of chromogranin A, while concentration of 5-hydroxyindoleacetic acid is helpful in the diagnostics of carcinoid syndrome. For visualisation, ultrasound, computed tomography, magnetic resonance imaging, colonoscopy, video capsule endoscopy, double-balloon enteroscopy, and somatostatin receptor scintigraphy may be used. A detailed his-tological report is crucial for the proper diagnostics and therapy of NENs of the small intestine and appendix. The treatment of choice is surgical management, either radical or palliative. The pharmacological treatment of the hormonally active and non-active small intestinal NENs as well as NENs of the appendix is based on long-acting somatostatin analogues. In patients with generalised NENs of the small intestine in progress during the SSA treatment, with good expression of somatostatin receptors, the first-line treatment should be radio-isotope therapy, while targeted therapies, such as everolimus, should be considered afterwards. When the above therapies are exhausted, in certain cases chemotherapy may be considered.

Pancreatic neuroendocrine neoplasms - management guidelines (recommended by the Polish Network of Neuroendocrine Tumours).

Endokrynol Pol 2017 ;68(2):169-197

This article presents updated diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine tumours (PNEN), proposed by the Polish Network of Neuroendocrine Tumours. The guidelines contain new data received in the years 2013-2016, which confirm previous recommendations, and have led to modification of previous guidelines or have resulted in the formulation of new guidelines. Biochemical and imaging (anatomical and functional) tests are of great importance in diagnostics, as well as histopathological diagnosis to determine the management of PNEN patients, but they must be confirmed by an immunohistochemical examination. PNEN therapy requires collaboration among the members a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment in many cases. Further therapy requires a multidirectional procedure; therefore, the rules of biotherapy, peptide receptor radionuclide therapy, molecular targeted therapy, and chemotherapy are discussed.

Risk factors assessment and risk prediction models in lung cancer screening candidates.

Ann Transl Med 2016 Apr;4(8):151

1 The Chair and Department of Thoracic Surgery, The Professor S. Szyszko Teaching Hospital No. 1, Zabrze, Poland ; 2 Department of Clinical Oncology, Medical University of Silesia, Katowice, Poland.

From February 2015, low-dose computed tomography (LDCT) screening entered the armamentarium of diagnostic tools broadly available to individuals at high-risk of developing lung cancer. While a huge number of pulmonary nodules are identified, only a small fraction turns out to be early lung cancers. The majority of them constitute a variety of benign lesions. Although it entails a burden of the diagnostic work-up, the undisputable benefit emerges from: (I) lung cancer diagnosis at earlier stages (stage shift); (II) additional findings enabling the implementation of a preventive action beyond the realm of thoracic oncology. This review presents how to utilize the risk factors from distinct categories such as epidemiology, radiology and biomarkers to target the fraction of population, which may benefit most from the introduced screening modality.

[Novel strategies of ovarian cancer treatment].

Pol Merkur Lekarski 2015 Nov;39(233):337-42

Silesian University of Medicine in Katowice, Poland: Department of Internal Diseases and Clinical Pharmacology.

Ovarian cancer is the most lethal gynecological malignancy. Due to scarce specific symptoms, women usually seek medical help once the disease is highly advanced, with distant metastases. Currently no screening is available, making this particular cancer hard to detect in the early stage. Standard treatment is insufficient for many patients, especially in the recurrent disease. This fact explains the tremendous need to search for novel therapeutic approaches. Inhibition of angiogenesis and destruction of cancer stem cells are attempts that affect the tumor microenvironment. There is a lot of potential in inhibiting poly(ADP-rybose)polymerase (PARP) or I class histone deacetylase. Drug repositioning may also be beneficial, as it gives old drugs new purposes. Metformin, a well-known antidiabetic agent, is an example of this phenomenon. Constant progress in medicine and science makes us hope for positive outcomes while treating this highly dangerous disease.

[Maternity after breast cancer treatment].

Ginekol Pol 2015 Jan;86(1):72-6

Recent years have seen a notable increase in the number of breast cancer diagnoses among women who have not fulfilled their maternity plans before the disease. Cytotoxic drugs (chemotherapy), used in the treatment of breast cancer patients, cause varying degrees of damage to the ovaries. The expected favorable effect of gonadoliberin analogues on the preservation of fertility has not been confirmed in clinical trials, and these drugs are currently not recommended for therapy. It is only the development of cryobiology and assisted reproduction techniques that make it possible to preserve the reproductive potential. The safety of the mother and the baby after breast cancer treatment is a separate issue. The available data indicate that both, pregnancy and breast-feeding are safe for the mother and the baby. However, the majority of findings come from retrospective studies covering small sample size and excluding the heterogeneity of both, cancer cells and patient clinical data.

Assessment of the safety and efficiency of sunitinib malate in metastatic neuroendocrine tumours of the pancreas (NEN G1/G2) depending on the number and type of earlier therapeutic lines - initial report.

Endokrynol Pol 2014 ;65(6):472-8

Division of Radiotherapy and Oncology, Department of Clinical Oncology, Silesian Medical University, Katowice, Poland.

Introduction: The objective of this paper was to assess the safety and efficacy of sunitinib malate in patients with well-differentiated metastatic pancreatic neuroendocrine neoplasms (PNENs) who relapsed on standard therapy.

Material And Methods: Overall, eight patients with well-differentiated pancreatic neuroendocrine tumours/neoplasm (NET/NEN G1/G2, Ki-67 < 20%), who had relapsed on a standard therapy approach, were treated. All had non-resectable, progressive disease. All received therapy using a standard dose of sunitinib malate. Adverse events were evaluated using NCI-CTC AE v. 3.0.

Results: Of the eight patients, seven had non-secretor and single secretor tumour (gastrinoma). Partial remission (PR) was noted in three patients (one after a single therapeutic line, two after two lines), five patients had stabilisation (SD) - including three individuals after three lines, one patient after two lines and another after a single line. Haematological adverse events: leukopenia (25%) - occurred in one patient after three lines and in one patient after two lines; anaemia (25%) - in one patient after three lines and in one patient after one therapeutic line. Mucocutaneous lesions were noted in 37.5% of patients after 2-3 lines of treatment. All of them experienced fatigue syndrome irrespective of the number of therapies. The majority of the patients simultaneously received somatostatin analogues, which did not exacerbate the toxicity profile. The median progression-free survival time (PFS) was 11 months.

Conclusions: Sunitinib may be considered as a fairly well-tolerated and effective therapeutic option in progressive non-resectable PNEN patients in the second and subsequent lines of treatment, irrespective of the types of treatment previously applied.

An atypical course of pancreatic neuroendocrine tumour manifesting as cardiac metastasis - a clinical case.

Endokrynol Pol 2014 ;65(3):232-9

Division of Clinical Oncology, Department of Oncology and Radiotherapy, Silesian Medical University, Katowice, Poland.

This paper presents a ten-year course of the disease in a patient with pancreatic neuroendocrine tumour NEN G1, and with confirmed single, asymptomatic metastasis to the left cardiac ventricle. Initially, the cardiac metastasis was visible only on a positron emission tomography (PET) scan using gallium-68-labelled somatostatin analogue; the sensitivity of an echocardiography scan was lower. Despite the advanced stage of the disease, surgical excision of the cardiac metastasis was performed. The patient underwent a total of eight operations, and received chemotherapy, radiotherapy and somatostatin analogues. Currently, he is on a targeted therapy with everolimus. As a result of the treatment, the patient remains in a good general condition. This is the second described case of cardiac metastasis of PNEN. Using different methods of treatment in the case of generalised pancreatic neuroendocrine tumour with low proliferative potential, patients are offered the chance to prolong their survival and maintain a good quality of life.

Associations between genes for killer immunoglobulin-like receptors and their ligands in patients with epithelial ovarian cancer.

Hum Immunol 2014 Jun 19;75(6):508-13. Epub 2014 Apr 19.

Center for Translational Research and Molecular Biology of Cancer, Maria Sklodowska-Curie Memorial Cancer Center and Institute of Oncology, Gliwice, Poland.

Killer immunoglobulin-like receptors (KIRs) regulate function of NK cells and subsets of T cells. HLA class I molecules are ligands for inhibitory KIRs while specificity of activating KIRs is mainly unknown. Both KIR and HLA genotypes are highly polymorphic. In this study we analyzed associations of KIR and KIR ligand genes with the incidence and clinical course of epithelial ovarian cancer. DNA of 142 patients was analyzed for KIR genes and 103 samples were typed for HLA class I. Control group consisted of 200 healthy individuals, including 83 women, analyzed separately. The frequency of KIR genes in patients and controls were comparable. HLA-C group 1 (ligand for KIR2DL2/3) was more frequent in patients than in controls (86.4% vs. 67.5%, p=0.002). The frequency of KIR2DS4fl was higher in patients with endometrioid cancer (72.3%) compared with other histological subtypes (36.5%, p=0.004) and controls (29.5%, p=0.0001). KIR and KIR ligand genotype did not influence significantly the clinical course of the disease. We conclude that the genotype of KIR ligands is strongly associated with the incidence of epithelial ovarian cancer while KIR2DS4fl confers susceptibility to endometrioid subtype of the disease.

Chemotherapy for gastric cancer patients - time for personalization in medicine?

Contemp Oncol (Pozn) 2012 29;16(1):86-9. Epub 2012 Feb 29.

Clinical and Experimental Oncology Department, Cancer Centre - Institute of Oncology - MSC Gliwice Branch, Poland.

Gastric cancer is one of the most frequent neoplasms. Although the incidence of gastric cancer worldwide has declined, there is still high mortality. Treatment of inoperable disease is under evaluation in clinical trials. In palliative treatment chemotherapy containing cisplatin and 5-fluorouracil is the most widely used. In the past years progress in tumour biology has advanced greatly and has led to development of new molecules aimed at targets important for cancer expansion. There are several randomized trials under targeted therapies for gastric cancer patients. One of them led to approval of trastuzumab. In the current paper the authors illustrate new possibilities in systemic treatment with particular attention to targeted therapy and personalization in medicine.
