Abstrakt: Purpose: To compare the oncological outcomes between standard radical cystectomy (SRC) and organ-sparing cystectomy (OSC) in male patients diagnosed with bladder cancer.
Methods: Patients with stage Ta-T3 bladder cancer who underwent OSC or SRC were identified from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. The association between preoperative factors and the implementation of OSC was analyzed using logistic regression. Propensity score matching (PSM) was employed to balance baseline characteristics between the two groups. Patients' overall survival (OS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Subgroup analyses based on the T stage were also conducted.
Results: A total of 7264 patients were included, with 96.8% (7033 patients) receiving SRC and 3.2% (231 patients) receiving OSC. Patients with higher T stages and high-grade tumors were less likely to undergo OSC. After PSM, OSC was associated with significantly worse OS and CSS than SRC. Subgroup analysis revealed that OSC did not lead to worse OS and CSS in non-muscle invasive bladder cancer and T2 stage patients, but it resulted in significantly worse outcomes in T3 stage patients.
Conclusion: Our study indicates that OSC is associated with poorer oncological outcomes compared to SRC, particularly in patients with advanced-stage tumors. These findings suggest the need for stringent selection criteria for OSC in bladder cancer patients. Given the negative impact on prognosis, stage T3 should potentially be considered a contraindication for OSC. Further evidence is required to confirm these assertions.
