Low Survival in Poor Prognosis Metastatic Germ Cell Cancer in Belarus.

Purpose: Since the development of the International Germ Cell Cancer Collaborative Group (IGCCCG) risk classification in a 1997 study, high-income countries have reported a significant increase in survival for poor prognosis patients. There are scant data on IGCCCG risk-stratified survival from low- and middle-income countries. We assessed the progression-free survival (PFS) and overall survival (OS) rates in a contemporary cohort of Belarusian patients with advanced germ cell cancer (GCC) stratified by the IGCCCG prognostic classification and analyzed prognostic factors for survival.

Overall survival in patients with metastatic renal cell carcinoma in Russia, Kazakhstan, and Belarus: a report from the RENSUR3 registry.

Background: Real-world data describing outcomes of treatment among metastatic renal cell carcinoma (mRCC) patients are limited and heterogeneous.

Aim: RENSUR3 registry study assessed real-world data on the use of therapies in mRCC and overall survival (OS) in Russia, Kazakhstan, and Belarus.

Methods: Patients were included in the retrospective multicenter registry study.

Long-term results of a single-center prospective randomized trial assessing efficacy of a shortened course of adjuvant chemotherapy after radical cystectomy in patients with locally advanced bladder cancer.

Introduction: This study assesses the efficacy and tolerability of two cycles of adjuvant chemotherapy (AC) with gemcitabine and cisplatin after radical cystectomy in patients with a high risk of progression of muscle-invasive urothelial bladder cancer as compared to chemotherapy at relapse, in a prospective randomized study.

Material And Methods: From 2008 to 2013, all patients after radical cystectomy at our institution for primary or recurrent urothelial bladder cancer with stage pT3-4 and/or pN+ on histopathology and without contraindications to combination cisplatin-based chemotherapy, were randomized either to two cycles of gemcitabine and cisplatin chemotherapy or to follow-up and chemotherapy at the time of relapse. The study endpoints were overall, cancer-specific, and disease-free survival.

Trends in incidence, mortality and survival of testicular cancer patients in Belarus.

Introduction: The objective of this study was to assess recent trends in incidence, mortality and relative survival (RS) in testicular cancer (TC) patients in Belarus and to provide international comparisons of our figures.

Material And Methods: We surveyed the Belarusian Cancer Registry for all male cases diagnosed with International Classification of Diseases for Oncology, third edition (ICD-O-3) topography code C62 between 1990 and 2015. Trends for incidence and mortality rates per 100,000 of the world standard population and annual percentage changes (APCs) were calculated.

Efficacy of fluorescent cystoscopy-assisted transurethral resection in patients with non-muscle invasive bladder cancer and quality of surgery: post-hoc analysis of а prospective randomized study.

Introduction: This paper aims to evaluate the influence of quality of transurethral resection in patients with non-muscle invasive bladder cancer on the benefit of fluorescent cystoscopy-assisted transurethral resection in the post hoc analysis of the single-center randomized controlled trial.

Material And Methods: We retrospectively analyzed the results of the prospective randomized study assessing the efficacy of fluorescent cystoscopy-assisted transurethral resection. The quality of transurethral resection was defined on the basis of a separate retrospective study estimating the variability in recurrence risk for the individual surgeon.
