Introduction:
We aimed to investigate the long-term outcome of trimodality therapy consisting of transurethral resection of bladder tumor, external beam radiation therapy, and concurrent intra-arterial low dose cisplatin for patients with muscle invasive bladder cancer.
Materials And Methods:
We retrospectively reviewed the medical records of 37 consecutive patients (28 men and 9 women) who underwent trimodality therapy for T2-3N0M0 bladder cancer at our hospital between 1996 and 2011. A total of 60Gy of external beam radiation therapy was administered. A daily low dose of cisplatin was administered intra-arterially through a subcutaneously placed reservoir on the days of radiation therapy. Complete response was defined as no residual cancer in transurethral resection specimens and negative cytology. When a complete response could not be achieved, patients underwent additional intra-arterial chemotherapy.
Results:
Five-year cause specific, disease free, and overall survival rates were 86.4%, 69.7%, and 69.6%, respectively, with a mean follow-up period of 56.5 ± 6.1 months. Five-year cause specific survivals of the complete response group after the trimodality therapy, the complete response group after additional intra-arterial chemotherapy and the non-complete response group were 100% (n = 21), 85.9% (n = 9) and 0% (n = 7), respectively. Five-year overall survivals of the complete response group after the trimodality therapy, the complete response group after additional intra-arterial chemotherapy and the non-complete response group were 82.8%, 85.3% and 0%, respectively.
Conclusions:
This trimodality therapy for muscle invasive bladder cancer could achieve favorable survival rates with bladder preservation and minimal adverse events. This trimodality therapy can be one of the useful treatment options.
