Purpose:
We sought to define patient and disease characteristics associated with outcomes after trimodality therapy (TMT) for high-risk nonmuscle invasive and muscle invasive bladder cancer (MIBC). A retrospective analysis of a large single institution cohort treated with bladder preservation therapy was performed to identify factors associated with survival.
Methods And Materials:
Patients with high-risk non-MIBC or MIBC who underwent definitive bladder sparing treatment between 2006 and 2022 were included. Variables for analysis included age, sex, Charlson Comorbidity Index (CCI), surgical candidacy, neoadjuvant/induction chemotherapy (NAC), tumor size, presence of hydronephrosis, carcinoma in-situ, and histologic subtype. Kaplan-Meier analysis was done to calculate rates of overall survival (OS) and disease-free survival (DFS), while cumulative incidence analysis was done to calculate rates of cancer specific mortality (CSM) and local recurrence. Cox proportional hazards regression was done to identify factors associated with OS and DFS. Competing risk regression was done to identify factors associated with CSM and local recurrence.
Results:
226 patients were included in the cohort with a median follow up of 18.9 months (range 0.9-172.3). The median age was 79 years (range 49-98) and 79.2% were male. On univariate Cox proportional hazards regression, younger age, NAC, and cystectomy candidacy were associated with improved OS (P < .0001, HR = 1.05, 95% CI, 1.03-1.08; P = .04, HR = 0.62, 95% CI, 0.39-0.99; P < .0001, HR = 0.42, 95% CI, 0.27-0.65; respectively). On multivariable analysis, only younger age and cystectomy eligibility were associated with improved OS (P = .002, HR = 1.04, 95% CI, 1.02-1.07; P = .006, HR = 0.52, 95% CI, 0.33-0.83; respectively).
Conclusion:
This study finds cystectomy eligibility to be associated with improved survival and underscores the importance of multi-disciplinary assessment in determining candidacy for organ preserving therapy in MIBC patients.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
