Neoadjuvant Intra-Arterial Chemotherapy in the Treatment of Advanced Transitional Cell Carcinoma of the Bladder: Results and Followup

Abstract

The long-term results of regional chemotherapy plus intra-arterial cisplatin with or without doxorubicin as an adjuvant before cystectomy and urinary diversion in patients with invasive transitional cell carcinoma of the bladder were evaluated. A total of 27 patients with T3aNxMo (8), TSbNxMo (14) and T4NxMo (5) disease participated in a phase II trial completed in 1985. Of the patients 19 received cisplatin and doxorubicin intra-arterially, and cyclophosphamide intravenously, and the remaining 8 received 70 to 100mg. per m.2 cisplatin intra-arterially. A total of 19 patients underwent cystectomy after chemotherapy. Patients in this group had a pathological complete response (no evidence of disease after surgical restaging) or the presence of residual disease at operation that could (surgical complete response) or could not (pathological partial response) be completely resected. Of the 19 patients undergoing cystectomy surgical complete response was observed in 47.4%, pathological complete response in 26.3% and pathological partial response in 26.3%. At a median followup of 27 months for the group 66% of the patients with a surgical complete response, 100% with a pathological complete response and 40% with a pathological partial response were alive with no evidence of disease. The over-all survival for patients with a pathological or surgical complete response is 76.9%. In the patients not operated upon because of persistent or advanced disease after chemotherapy survival was brief (less than 4 months). Prolonged survival in patients achieving a pathological or surgical complete response with neoadjuvant chemotherapy occurs, and this modality may have a role in patients with invasive tumors. (J.
