Comparative survival following different treatment modalities for stage T2 bladder cancer in octogenarians

Abstract

Purpose: A higher rate of comorbidities and an anticipated higher operative risk in octogenarians may influence urologists in opting for less aggressive and less effective treatment modalities for muscle-invasive bladder cancer. This study was performed to compare survival after different treatment modalities in octogenarians with stage T2 bladder cancer.

Methods: Patients that were 80 years or older with a diagnosis of transitional cell carcinoma of the bladder were identified using the Surveillance, Epidemiology, and End Results-17 registry database between 1988 and 2007. Patients were analyzed for treatment method and outcomes, including overall survival (OS) and cancer-specific survival (CSS).

Results: A total of 3,232 patients met inclusion criteria. Of these, 69 % (N = 2,216) underwent only transurethral resection (TURBT), 23 % (N = 733) underwent pelvic radiation therapy (RT), and 9 % (N = 283) underwent definitive surgical therapy. The 3-, 5-, and 10-year OS rates were 22.2, 15.0, and 4.4 %, respectively, for TURBT; 27.8, 18.3, and 3.5 % for RT; and 52.7, 39.1, and 17.2 % for definitive surgery. The 3-, 5-, and 10-year CSS rates were 38.3, 33.4, and 27.4 %, respectively, for TURBT; 41.6, 35.0, and 27.2 % for RT; and 66.6, 55.5, and 49.9 % for definitive surgery. Both partial and radical cystectomy had significantly longer CSS rates at 3 and 5 years when compared to RT (p ≤ 0.001).

Conclusions: Compared to other treatment modalities, surgery, either radical cystectomy or partial cystectomy, offers the best OS and CSS for men aged 80 years or older with T2 bladder cancer.
