Immunotherapy in the treatment of lymphoma.

World J Stem Cells 2021 Jun;13(6):503-520

Department for Medical Oncology, Oncology Institute of Vojvodina, Novi Sad 21000, Serbia.

Relapsed or refractory non-Hodgkin's lymphomas, especially diffuse large B-cell lymphoma as well as relapsed or refractory Hodgkin lymphomas are hard-to-treat diseases. Patients who do not respond to initial therapy or experience relapse are treated with salvage regimens, and if eligible for aggressive therapy, treatment is continued with high-dose chemotherapy and autologous stem cell transplantation. Current therapy options can cure substantial numbers of patients, however for some it is still an uncurable disease. Numerous new drugs and cell therapies are being investigated for the treatment of relapsed or refractory lymphomas. Different types of immunotherapy options have shown promising results, and some have already become the standard of care. Here, we review immunotherapy options for the treatment of lymphoma and discuss the results, positions, practical aspects, and future directions of different drugs and cellular therapies for the treatment of this disease.

Prospective Non-Randomized Study of Intraoperative Assessment of Surgical Resection Margin of Colo-Rectal Liver Metastases.

J Cancer 2021 30;12(12):3701-3714. Epub 2021 Apr 30.

Uniformed Services University of the Health Sciences, Bethesda, Maryland, USA.

More than 50% of patients with colorectal cancer (CRC) develop liver metastases during the natural course of disease. Surgical resection is currently the most potentially curative method in the treatment of colorectal liver metastases (CRLM). The goal of surgery is to achieve a negative resection margin (RM) of at least 1 mm, which provides the best prognosis for patients. The RM can be assessed by the pathologist of the resected liver specimen (RLS) and by the surgeon intraoperatively. The aim of this research paper is to determine the degree of agreement on intraoperative assessment of the RM by the surgeon and histopathological RM assessment by the pathologist. This prospective non-randomized double-blind study was approved by the Ethics Committee of the Oncology Institute of Vojvodina and registered on ClinicalTrials.gov #NCT04634526. The study was conducted at the Oncology Institute of Vojvodina, Sremska Kamenica, Serbia. An experienced hepatobiliary surgeon assessed RM for every specimen intra-operatively, immediately after CRLM resection. Resected CRLM lesions were analyzed by two experienced pathologists. These data were compared with pathological RM assessment as a "gold standard". RM of 1 mm or more was rated as negative RM (RM-). Disease-free survival (DFS) and recurrence rate was calculated by RM status defined by surgeon and by pathologist. From 01 January 2015 to 31 August 2019, 98 patients were enrolled in the study. There were 219 RLS with 245 CRLM. The surgeon registered positive RM (RM+) of <1mm in 41 (18.7%) RLS. Taking the result of the histopathological assessment (HPA) as the "gold standard", it was determined that RM was true positive in 32 (14.6%) cases. False positive RM was found in 9 (4.1%) cases. False negative RM was found in 20 (9.1%) cases. True negative RM was found in 158 (72.2%) cases. Sensitivity of surgical assessment (SA) of RM+ was 61.5% (32/52). Specificity of SA of RM+ was 94.6% (158/167). The positive predictive value (PPV) was 78.0% (32/41), while the negative predictive value (NPV) was 88.8% (158/178). The overall accuracy of the RM+ SA was 86.8% (190/219). There was no statistically significant difference in the assessment of RM+ per RLS by surgeon and pathologists (p=0.061), but it was significant when analyses per patients was performed (p=0.017). Recurrence rate for RM+ patients was 48.1% (13/27, p=0.05) for SA and 35.0% (14/40, p=0.17) for HPA. Three year DFS for RM- and RM+ was 66.5% and 27.9% (p=0.04), respectively, by SA, and 64.8% and 42.1% (p=0.106), respectively, by HPA. Intraoperative assessment of RM- by surgeon of RLS is clinically meaningful. There is not a statistically significant difference in the assessment of RM+ by surgeon and pathologists per RLS, but it was statically significant on a per patient basis. RM determined by surgeon has better prognostic impact on recurrence rate and 1- and 3-year DFS than standard histopathological assessment.

Intratumoral Treatment with Chemotherapy and Immunotherapy for NSCLC with EBUS-TBNA 19G.

J Cancer 2021 5;12(9):2560-2569. Epub 2021 Mar 5.

Department of Pulmonology, University Hospital Zurich, Rämistrasse 100, 8091, Zurich Switzerland.

Immunotherapy is being used for the past five years either as first line or second line treatment with great results. Chemotherapy and radiotherapy have been also used as combination to immunotherapy to further enhance this type of treatment. Intratumoral treatment has been previously proposed as a treatment option for certain non-small cell lung cancer patients. We recruited in total seventy four patients with non-small cell lung cancer in their second line treatment who received only chemotherapy in their first line treatment with programmed death-ligand-1 ≤ 50. Only adenocarcinoma or squamous cell carcinoma, and all negative for epidermal growth factor receptor, anaplastic lymphoma kinase, proto-oncogene tyrosine-protein kinase-1 and proto-oncogene B-Raf. Data were first examined with descriptive statistics choosing frequencies for categorical variables and histograms for the continuous ones. Twenty five received only intravenous immunotherapy and forty-nine intravenous cisplatin with immunotherapy. Data were first examined with descriptive statistics choosing frequencies for categorical variables and histograms for the continuous ones. The relationships between changes of performance status and disease progression were examined via a single correspondence analysis. The two-dimensional scores (coordinates) derived from the correspondence analysis were then regressed against the predictors to form distinct splits and nodes obtaining quantitative results. The best fit is usually achieved by lowering exhaustively the AICc criterion and looking in parallel the change of R expecting improvements more than 5%. both types of therapy are capable of producing best ameliorative effects, when either the programmed death-ligand-1 expression or parenchymal site in joint with low pack years are present in the sampling data. Intratumoral treatment combination with cisplatin plus immunotherapy indifferent of nivolumab or pembrolizumab combination is an effective choice. In specific for those with endobronchial lesions. Moreover; patients with programmed death-ligand-1 ≥ 50 had their performance status and disease progression improved over the eight month observation.

Thyroid cancer diagnosis with transdermal probe 22G U/S versus EBUS-convex probe TBNA-B 22G and 19G: pros and cons.

Expert Rev Med Devices 2021 Feb 29;18(2):197-201. Epub 2021 Jan 29.

Surgery Department, ``Genesis`` Private Hospital, Thessaloniki, Greece.

Introduction: Thyroid cancer is usually diagnosed both with imaging techniques and transdermal biopsy. Laboratory tests are also included in the initial work-up.

Patients And Methods: One hundred and thirty patients were included in our study with pathological imaging findings in the thyroid region. Biopsies were performed with 22 G with transdermal convex probe, EBUS 22 G Mediglobe® needle and 19 G Olympus® needle. We investigated the efficiency and safety of both techniques and identified the best candidates for each method.

Discussion: 19 G needle identified cancer types such as; Lymphoma, Medullary thyroid cancer, and Hurthle cell cancer, which we know from previous pathology studies that a larger sample is necessary for diagnosis. No safety issues were observed for both techniques and the EBUS technique produced more cell block material when 22 G needle was compared to transdermal biopsy in peritracheal lesions.

Conclusion: The method of biopsy should be made based on the size and accessibility of the lesion.

Connection between PD-L1 expression and standardized uptake value in NSCLC: an early prognostic treatment combination.

Expert Rev Respir Med 2021 May 31;15(5):675-679. Epub 2020 Dec 31.

Department of Pharmacology & Clinical Pharmacology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Thessaloniki, Greece.

: Lung cancer is still diagnosed at advanced stage and early treatment initiation is needed. Therefore, we need biomarkers or clusters of information that can provide early treatment prognosis.: Biopsies were acquired from 471 patients-lung masses with CT-guided biopsy, convex probe transthorasic biopsy, and EBUS-TBNA convex probe with 18 G needles and 19 G needles.: Standardized uptake value (SUV) measurement is associated with female, smoking status, hepatic metastasis, adenocarcinoma and programmed death-ligand 1 (PD-L1). In specific we expect that SUV ≥ 7 is associated with PD-L1 ≥ 50.: Lung masses indifferent of size that have SUV ≥ 7 will also have PD-L1 expression ≥ 50. Also, it is likely that these patients will be female with intense smoking habit and hepar or multiple metastasis.

Lung cancer biopsies: Comparison between simple 22G, 22G upgraded and 21G needle for EBUS-TBNA.

J Cancer 2020 14;11(21):6454-6459. Epub 2020 Sep 14.

3rd University General Hospital, "AHEPA" University Hospital, Thessaloniki, Greece.

Novel technologies are currently used for lung cancer diagnosis. EBUS-TBNA 22G is considered one of the most important tools. However; there are still issues with the sample size. 223 patients underwent EBUS-TBNA with a 21G Olympus needle, 22GUS Mediglobe and 22GUB Mediglobe. In order to evaluate the efficiency of 22GUB novel needle design. In order to evaluate the sample size of each needle, we constructed cell blocks and measured the different number of slices from each biopsy site. The 22GUB novel needle had similar and larger number of slices from each biopsy site compared to 21G needle. Firstly as a novel methodology we used the number of slices from the constructed cell blocks in order to evaluate the sample size. Secondly, we should seek novel needle designs and not only concentrate on the volume of the sample size.

Early and long-term results of open repair of inflammatory abdominal aortic aneurysms: Comparison with a propensity score-matched cohort.

J Vasc Surg 2020 09 2;72(3):910-917. Epub 2020 Mar 2.

Faculty of Medicine, University of Belgrade, Belgrade, Serbia; Clinic for Vascular and Endovascular Surgery, Clinical Center of Serbia, Belgrade, Serbia.

Objective: The aim of our study was to compare early and long-term results of open repair of patients with inflammatory abdominal aortic aneurysm (IAAA) with matched cohort of patients with abdominal aortic aneurysm (AAA).

Methods: This retrospective single-center cohort study used prospectively collected data from an institutional registry from 1786 patients between 2009 and 2015. Patients with IAAA and AAA were matched by propensity score analysis controlling for demographics, baseline comorbidities, and AAA parameters in a 1:2 ratio. Patients were followed for 5 years.

Results: There were 76 patients with IAAA and 152 patients with AAA. Patients with IAAA had more common intraoperative lesion of intraabdominal organs (P = .04), longer in-hospital (P = .035) and intensive care (P = .048) stays and a higher in-hospital mortality rate (P = .012). There were four patients (5.26%) with in-hospital lethal outcome in IAAA there were no deaths in the AAA group. During the follow-up, there was no difference in survival (χ = 0.07; DF = 1; P = .80) and overall aortic related complications (χ = 1.25; DF = 1; P = .26); however, aortic graft infection was more frequent in IAAA group (P = .04).

Conclusions: Open repair of IAAA is challenging and comparing to AAA carries a higher perioperative risk and long-term infection rate, even in high-volume centers. The main causes of complications are intraoperative injury of adjacent organs, bleeding, and coronary events. Patients with AAA in a matched cohort showed equal long-term survival, which should be assessed in bigger registries.

Treatment of pediatric vascular injuries: the experience of a single non-pediatric referral center.

Int Angiol 2019 Jun 15;38(3):250-255. Epub 2019 Apr 15.

Faculty of Medicine, University of Belgrade, Belgrade, Serbia.

Background: Pediatric peripheral vascular trauma carries significant risk of complications including limb loss and long-term invalidity. Mechanisms and types of morphological lesions are very diverse. The objectives of this study are to present the experience of a single vascular center in the surgical approach to pediatric vascular injuries, and to analyze the main challenges related to this clinical entity.

Methods: Over a period of 25 years, 17 pediatric peripheral vascular injuries were treated in our institution. Patient's age ranged between one day (newborn) and 15 years (mean: 10.7 years). There were five injuries of upper and 12 injuries of the lower extremity. Preoperative diagnosis was established by clinical examination (N.=4), ultrasonography (N.=1) and angiography (N.=12). Blunt trauma mainly caused arterial thrombosis while penetrating trauma caused arterial laceration or complete transection. Five patients had associated orthopedic injuries (29,4%). There were two posttraumatic pseudoaneurysms and two arterio-venous fistulas.

Results: There was no perioperative mortality. Vascular reconstructions included arterial suture (N.=4), thrombectomy + patch angioplasty (N.=1), termino-terminal anastomosis (N.=3), venous anatomic bypass (N.=6), PTFE graft reconstruction (N.=2), and venous extra-anatomic reconstruction (N.=1). Two patients had associated venous injury demanding both arterial and venous reconstruction. In the only case of war trauma treatment ended with limb loss. Other reconstructions presented good early and long-term patency.

Conclusions: Pediatric vascular injuries are extremely challenging issues. Treatment includes broad spectrum of different types of vascular reconstructions. It should be performed by vascular surgeon trained in open vascular treatment or pediatric surgeon with significant experience in vascular surgery.

An Isolated Aneurysm of the Abdominal Aorta in a Patient with Marfan Syndrome-A Case Report.

Ann Vasc Surg 2020 Feb 11;63:454.e1-454.e4. Epub 2019 Feb 11.

Clinic for Vascular and Endovascular Surgery, Clinical Center of Serbia, Belgrade, Serbia; School of Medicine, University of Belgrade, Serbia.

We present a case of successfully treated abdominal aortic aneurysm in a 24-year-old patient with Marfan syndrome. After initial physical and ultrasound examination, the multislice computed tomography (MSCT) scan revealed infrarenal aortic aneurysm of 6 cm in diameter, 10 cm long, along with slightly dilated iliac arteries. However, dimensions of aortic root, aortic arch, and descending suprarenal aorta were within normal limits. Further on, because the patient presented with signs of impending rupture, an urgent surgical intervention was performed. The patient was discharged in good general medical condition 7 days after surgery. After 6 months of follow-up, the patient's condition was satisfying and no MSCT signs of further aortic dissection/aneurysm were identified. To the best of our knowledge, a case of successful management of a patient with Marfans syndrome and truly isolated infrarenal and symptomatic abdominal aortic aneurysm has not been described in the literature before.

Anaesthesia and the patient with diabetes.

Diabetes Metab Syndr 2015 Jul-Sep;9(3):177-9. Epub 2015 Apr 24.

Center for Anaesthesiology and Resuscitation, Clinical Center of Serbia, Belgrade, Serbia; School of Medicine, University of Belgrade, Serbia.

Aims: To provide updated knowledge regarding the airway management and the possibility of difficult intubation in diabetic patients.

Materials And Methods: We preformed a systematic literature review of the English language literature, published over the past 10 years which deals with this subject.

Results: The vast majority of the modern literature data supports the fact that diabetic population has higher risk for difficult intubation occurrence. The most important characteristics of diabetic patients that are considered to be contributing factors for the difficult intubation are obesity, increased neck circumference and stiff joint syndrome.

Conclusion: A special attention and thorough preoperative preparation should be given to patients with diabetes. In order to predict and prevent difficult intubation in these patients, further studies are needed to investigate this issue closely.

Unusual metastasis of esophageal cancer.

Vojnosanit Pregl 2014 Oct;71(10):975-7

Introduction: Carcinoma of the esophagus is in the eighth place by the frequency of malignant diseases and the sixth cause of death from cancer worldwide. It usually metastasizes to regional lymph nodes, liver, lungs, central nervous system, and bones, but metastases can appear to unusual locations such as facial skin and lips.

Case Report: We presented a 56- year-old man who reported to his physician because of upper lip swelling. A physical checkup of the patients also showed a lesion on the skin of the left temporal region and both lesions were biopsied. Based on the results of histopathological and immunohistochemical analyses of the samples a diagnosis of metastatic adenocarcinoma to the skin was established. Additional diagnostic procedures, including esophagogastroduodenoscopy, detected the infiltration into the distal part of esophagus, which was histopathologically confirmed as adenocarcinoma of esophagus. The results of positron emission tomography/computed tomography (PET/CT) examination showed the invasion of the disease. Because of the disease expansion, a multidisciplinary oncology team suggested chemo- and radiotherapy treatment. The patient has received 4 cycles of platinum-based chemotherapy so far.

Conclusion: The physicians should always consider unusual skin lesions as the first sign of cancer spreading.

Application of alternative medicine in gastrointestinal cancer patients.

Vojnosanit Pregl 2012 Nov;69(11):947-50

Clinic for Internal Medicine, Oncology Institute of Vojvodina, Sremska Kamenica, Serbia.

Background/aim: [corrected] Alternative medicine is a set of therapeutic procedures which are no part of official practice. At present, the use of alternative medicine among cancer patients is significant and the purpose of this study was to get more information on the methods and products of alternative medicine. Thus, the aim of the study was to determine the frequency of the use of alternative medicine among gastrointestinal cancer patients.

Methods: The research was conducted using an anonymous questionnaire in writing. We included 205 patients with the diagnosis of gastrointestinal malignancy in the study but the questionnaire was fulfilled by 193 patients and the presented data were based on their answers. The questions were about the sociodemographic characteristics of the patients, the reasons for their use of alternative medicine, and their information sources about alternative medicine. We divided existing alternative therapies into 6 categories: herbal therapy, special diets, psychotherapy, body-mind therapy, spiritual therapy, and other supplements.

Results: A total of 48 (24.9%) patients did not use any type of alternative therapy; 145 (75.1%) patients used at least one product and 124 (64.25%) patients used herbal preparations (beetroot juice was consumed by 110 [56.99%] patients); 136 (70.5%) patients were informed about alternative therapies by other patients; 145 (75.1%) used alternative medicine to increase the chances for cure; 88 (45.6%) of interviewed patients would like to participate in future research in this field.

Conclusion: The use of alternative medicine is evidently significant among cancer patients. Further research should be conducted in order to find out interactions of these products with other drugs and potential advantages and disadvantages of this form of treatment.

Uncommon metastatic site from breast cancer.

Vojnosanit Pregl 2012 Sep;69(9):806-8

Clinic for Internal Medicine, Oncology Institute of Vojvodina, Sremska Kamenica, Serbia.

Introduction: Breast cancer is one of the most common malignancies in women and the main leading cause of cancer death. The most frequent sites of metastases from breast cancer are bones, lungs, the central nervous system, the liver and soft tissue. Colonic metastases from breast cancer are rare.

Case Report: We presented a 70-year-old woman with bulky obstructing lesion of sigmoid colon. A physician in charge on our department examined the patient and past history of breast cancer was found up. Surgery was performed with removal of sigmoid colon and three of six lymph nodes were positive. Pathological examination, including immunohistochemical stains, confirmed the diagnosis of metastatic breast cancer to sigmoid colon. The multidisciplinary oncology team suggested postoperative chemotherapy. The patient received four cycles of chemotherapy with paclitaxel followed by anastrozole. On the first control visit no disease activity was detected.

Conclusion: In patients with the past history of breast cancer the symptoms of hematochezia or anemia may indicate colonic metastases.
