    Notes: Summary A retrospective analysis of the prognostic value of pretreatment histology and expression of human chorionic gonadotrophin (B-hCG) was carried out in 100 invasive (T2/T3) transitional cell carcinomas of the bladder treated in a uniform manner. After transurethral resection of the tumour, all patients received a course of radical radiotherapy, with salvage cystectomy for those who failed to respond. Forty-nine of 100 patients responded to radiation; thus 51 did not. Forty-seven of 60 (78%) patients whose tumours contained areas of squamous differentiation and 22 of 29 (76%) of tumours staining positively for HCG failed to respond to radiotherapy. Twenty-two of 23 (96%) patients with tumours that had both these features did not respond to radiotherapy. The other histological features studied (grade of tumour, necrosis, inflammation, vascular invasion, and growth pattern) appeared unrelated to each other or to clinical outcome.

    Notes: Summary Many chemotherapeutic drugs have been used to treat patients with advanced bladder cancer, but few of these have been evaluated adequately in phase II clinical trials. Continuous cell lines provide one means for comparing the in vitro cytotoxicities of anticancer agents. In this study, a continuous cell line derived from a transitional cell cancer of the human bladder, which still produces tumours histologically similar to the tumour of origin on xenotransplantation, was used to measure the in vitro cytotoxicities of twelve chemotherapeutic drugs by clonogenic assay. The most cytotoxic agents tested were methotrexate, mitoxantrone, adriamycin, mitomycin C and cisplatin. These in vitro findings are compatible with the activity of these drugs given systemically as single agents in phase II clinical trials in patients with advanced bladder cancer.
