Abstract
Since 1976, a series of phase II studies with screening of various chemotherapeutic agents in invasive bladder cancer have been conducted at the National Cancer Institute, Cairo. Different drugs were screened, one by one, in groups of 20-25 patients with inoperable, metastatic, or recurrent carcinomas. Evaluation was done by clinical bimanual examination, radiography, sonography, cystoscopy, and urine cytology. In these trials bleomycin and doxorubicin were ineffective. Tenoposide, 5-fluorouracil, methotrexate, and cisplatin had minimal or moderate effect (response rates 4-16%). More pronounced effect was found for dibromodulcitol, cyclophosphamide, pentamethylmelamine, etoposide, hexamethylmelamine, ifosfamide, vindesine, vincristine, and epidoxorubicin (response rates 18-60%). Some complete responders remained in response for a period of 3-7 years. Drugs seemed to be more effective in metastatic than in local lesions.
