Neoadjuvant or definitive alternating chemotherapy and radiotherapy for infiltrating bladder cancer.
Thirty-two patients with infiltrating bladder cancer were treated with transurethral resection followed by one course of alternating chemoradiotherapy before radical cystectomy (group A, 20 patients) or two courses as definitive procedure (group B, 12 patients). One course consisted of: cisplatin 20 mg/m2 i.v. and 5-fluorouracil 200 mg/m2 i.v. for 5 consecutive days, the first and the fourth weeks; radiotherapy 20 Gy in 10 fractions in the second and third weeks. At the seventh week the same integrated therapy was restarted in group B. All 32 patients were evaluable for toxicity after the first course: no grade IV toxicity was observed. Significant increase in hematological toxicity was observed in 12 patients who received the second course of chemoradiotherapy: two patients had grade IV toxicity, and five patients had grade III. Fifteen patients of group A underwent radical cystectomy: 40% had a pathological (p) complete response (CR) and 13.3% a partial response Five patients in group A did not receive either the second course of therapy or cystectomy because of age (three patients), vascular obliteration (one patient) and enteritis (one patient). Actuarial disease-free survival in group A is 78% at 21 months. All patients of group B obtained clinical (c) CR and all but one have no evidence of disease at a median follow-up of 10 months (range 6-13). The high pCR and cCR obtained in patients of group A and group B, respectively, appears promising. A longer follow-up and a larger number of patients is required to determine the role of this integrated treatment.
