Influence of Primary or Secondary Muscle Invasive Bladder Cancer on Oncologic Outcomes After Radical Cystectomy
Journal Title: The Bulletin of Urooncology - Year 2020, Vol 19, Issue 4
Abstract
Objective: In this study, we aimed to investigate the oncologic outcomes of patients who were diagnosed with primary (muscle invasive cancer at the time of diagnosis) and secondary (cancer that showed progression from non-muscle invasive bladder cancer) muscle invasive bladder carcinoma (MIBC) before radical cystectomy (RC). Materials and Methods: Patients who underwent RC at our clinic for MIBC between July 2008 and June 2017 were included in the study. They were divided into two groups based on their diagnosis as primary and secondary MIBC. Their clinical, pathological, and oncologic data (upstaging, adjuvant chemotherapy, overall mortality, overall survival, cancer-specific mortality, and cancer-specific survival) were evaluated retrospectively. Results: A total of 80 patients underwent RC due to bladder cancer with a mean age of 64.4±7.8 years (range: 42-83 years) and a mean follow-up time of 32.9±32.1 months (range: 1-113 months). The overall and cancer-specific survivals of the patients were 64.7±6.6 and 74±6.8 months, respectively. Sixty-five and 15 patients were evaluated in the primary and secondary MIBC groups, respectively. Lymph node metastasis was higher in primary MIBC group (p=0.031). Although, there were no statistical differences between the groups, in secondary MIBC group, the overall survival (67.3±7.2 months vs 42.5±8.4 months; p=0.835) and cancer-specific survival (77.6±7.4 months vs 46.6±8.6 months; p=0.546) were lower, while the overall mortality (44.6% vs 53.3%; p=0.372) and cancer-specific mortality (32.3% vs 46.7%; p=0.293) were higher compared to primary MIBC group. Conclusion: The pre- and postoperative pathological T stages were similar between the groups, whereas postoperative lymph node positivity was lower for secondary MIBC patients. The mortality was higher and overall and cancer-specific survivals were lower in secondary MIBC patients; however, these findings were not statistically significant.
