[Concurrent chemotherapy and hyperfractionated radiotherapy for non-operable carcinoma of the bladder]

Two sequences of concomitant chemotherapy with 5-FU + cisplatin and hyperfractionated radiotherapy (67.2 Gy/56 fractions/38 days, two fractions of 1.2 Gy per day spaced to 6 hours) in the bladder volume were administered to 17 patients with infiltrative carcinoma of the bladder (1 pT1, 6 pT2, 8 pT3a, 2 pT3b or pT4, 8/17 N0-2). They were separated by an interval of 21 days with an intermediate bladder tumor evaluation. A complete histological response was observed in 69% (11 of 16 evaluable patients). With a mean follow-up of 21 months, the bladder preservation was stated in 8/11 (73%) of patients treated, of whom 6 with a complete tumor response, and 2 with a pTa recurrence; these results are similar to other series reported with conventional radiation therapy. No deficit in the bladder was observed in these eight patients.
