“…Previous studies investigating the association between female sex and survival outcomes in patients with MIBC have indeed shown conflicting results. Some studies have confirmed that female sex is associated with worse CSS outcomes, indicating a potentially poorer prognosis for women with MIBC [17,18]. Another study has suggested that female sex is associated with a higher rate of local-regional cancer control failure in high-stage bladder cancer patients after RC [19].…”

Purpose: Although radical cystectomy (RC) and concurrent chemoradiotherapy (CCRT) are curative options for muscle-invasive bladder cancer (MIBC), the optimal treatment strategy for MIBC patients with a history of nephroureterectomy for upper tract urothelial carcinoma (UTUC) remains unclear. This retrospective analysis was conducted to compare survival rates and evaluate prognostic factors related to treatment outcomes.Materials and Methods: We conducted a multi-institutional retrospective study of patients with MIBC after nephroureterectomy for UTUC between 2005 to 2023. Out of 75 patients, 30 underwent bladder-preserving therapy (BPT), including 22 patients who underwent radiation therapy (RT) and 8 patients who underwent CCRT, while 45 patients underwent RC. The overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS) after BPT and RC were evaluated using Kaplan-Meier curves. Cox regression analysis was used to identify variables associated with OS, CSS, and PFS. Posttreatment changes in renal function were compared.Results: At 3 years, the OS, CSS, and PFS rates in the BPT group were 52.4%, 71.7%, and 31.3%, respectively, with no significant difference compared to RC. In multivariate analysis, bladder cancer T stage was the only predictive factor for OS, CSS, and PFS. Similar results were also observed in the RT group compared to RC. A significant decrease in renal function was detected among patients in the RC group, while patients in the BPT group maintained preserved renal function. Patients in the BPT group experienced a lower grade of toxicity after treatment compared to those in the RC group, and the rates of survival with functional bladder at 1 year, 3 years, and 5 years were 87.0%, 69.9%, and 69.9%, respectively.Conclusions: Bladder-preserving therapy, including RT alone, may be a viable treatment option for patients with MIBC who have undergone nephroureterectomy, as it can achieve comparable oncologic outcomes to RC, while potentially preserving bladder and renal function.
