More than 430,000 new cases of renal cell carcinoma (RCC) were reported in 2020. Clear cell RCC, which occurs in 80% of cases, is often associated with mutations in the VHL gene, leading to dysregulation of hypoxia-induced transcription factors pathways and carcinogenesis. The purpose of this study is to examine the adverse events (AEs) of cabozantinib treatment and the relationship between individual patient factors and the frequency of their occurrence in detail.

Cabozantinib, an oral inhibitor targeting MET, AXL, and VEGF receptors, has become a key component of a sequential treatment strategy for clear cell renal cell carcinoma (ccRCC). The purpose of this work is to show that effective management of adverse events (AEs) during cabozantinib treatment and achieving a balance between AEs and treatment efficacy is crucial to achieving therapeutic goals. In this retrospective study, involving seventy-one metastatic RCC (mRCC) patients receiving second or subsequent lines of cabozantinib at the Department of Genitourinary Oncology, Maria Sklodowska-Curie National Research Institute of Oncology, we explored the impact of AEs on overall survival (OS) and progression-free survival (PFS).

Introduction: Cabozantinib is an oral inhibitor of MET, AXL, and vascular endothelial growth factor receptors. It has an immunomodulatory effect and may influence the tumor's microenvironment and make mutated cells more sensitive to immune-mediated killing. These properties have made cabozantinib an effective drug for first-line or subsequent-line treatment after progression of metastatic renal cell carcinoma (mRCC), even after immunotherapy.

Introduction: Geriatric patients with metastatic renal cell carcinoma (mRCC) are underrepresented in clinical trials. Evaluation of the efficacy of the treatment and assignation of individuals to proper prognostic groups is an absolute necessity to guarantee them the best possible care.

Material And Methods: A total of 138 geriatric patients with mRCC treated with first-line tyrosine kinase inhibitors (TKIs) at the Maria Skłodowska-Curie National Research Institute of Oncology were retrospectively analyzed to determine whether the body mass index (BMI) and pan-immune-inflammation value (PIV) are prognostic values for overall survival (OS) and progression-free survival (PFS) in this type of cancer.

Introduction: Urothelial carcinoma is the most common type of urinary tract malignancy. Current treatment options, including platinum-based chemotherapy or immunotherapy, present significant challenges, ranging from limited efficacy to severe toxicities. Recent developments in antibody-drug conjugates (ADC), such as enfortumab vedotin (EV), promise to significantly improve overall survival.

Renal cell carcinoma is the 14th most common cancer worldwide. It is a heterogeneous group of histopathological entities, of which the most common is clear cell renal cell carcinoma. Approximately 20-30% of patients present initially with metastatic disease and an additional 20% will progress after radical surgical treatment.

Introduction: Penile cancer is rare, and data on prognostic factors of the disease are scarce. The aim of the study was to assess prognostic factors in patients undergoing lymphadenectomy for penile cancer.

Material And Methods: Ninety-eight men who underwent lymphadenectomy for penile cancer were enrolled in the study.
