We describe 3 patients with metastatic transitional cell carcinoma of the prostate who achieved a complete response with regimens containing cisplatin. Two patients received cyclophosphamide and weekly cisplatin, and 1 was given cyclophosphamide, doxorubicin and cisplatin. All 3 patients had extensive pulmonary metastasis at initiation of chemotherapy. One patient, who also had massive local disease, suffered an isolated brain metastasis 9 months after completion of chemotherapy but he remains in systemic remission 5 months later. Another patient had bilateral brain metastases 3 months after achieving complete remission with chemotherapy, followed 4 months later by systemic relapse. The third patient, who also had bone and bone marrow metastasis, is free of disease 20 months after completion of chemotherapy. In contrast, none of 14 patients with transitional cell carcinoma of the bladder and other sites treated with the same regimens obtained a complete response. Advanced transitional cell carcinoma of the prostate must be recognized promptly, since it is nonresponsive to hormonal manipulation and complete responses have been achieved with cisplatin chemotherapy programs as used in our patients.
