Bladder-conserving Approach in Radical Treatment of Patients With Bladder Cancer - A Single-institution Experience

To evaluate our experience with radical radiotherapy and chemotherapy in patients with muscle-invasive bladder cancer.

The study consisted of 27 patients treated with cisplatin-based chemoradiation (CCRT), 48 treated with radiation alone (RT), and 42 with locally advanced disease treated with neoadjuvant chemotherapy and radiation (neoCRT).

The incidence of acute grade 3 or more genitourinary (GU) toxicity in the RT, CCRT and neoCRT groups was: 25%, 11% and 19%, respectively (p=0.029). The 3-year freedom from grade 2 or more GU toxicity was: 81%, 89%, 54%, respectively (p=0.36). The long-term outcomes of 3-year local control, overall survival, and disease-free survival were as follows: RT group: 74%, 61% and 55%; CCRT group: 76%, 76% and 56%; neoCRT group: 31%, 43% and 18%, respectively.

The preferable bladder-conserving approach is CRT, however RT alone might also be an option for appropriately selected patients. NeoCRT for those with locally advanced tumors remain unsatisfactory; adequate selection of patients for radical treatment is of importance.
