Abstract
The feasibility of adjuvant cisplatin, methotrexate and vinblastine chemotherapy was evaluated in Taiwanese patients with invasive transitional cell carcinoma at high risk for recurrence. We assigned 56 patients with high risk transitional cell carcinoma (vascular or lymphatic invasion in the primary tumor, poorly differentiated stage P2, P3, P4 or N+ and M0) to receive adjuvant chemotherapy after radical urological surgery. The chemotherapy consisted of 40 mg./m.2 methotrexate and 4 mg./m.2 vinblastine on days 1 and 8, and 100 mg./m.2 cisplatin on day 2 given in 6 courses at 21-day intervals. Median followup was 44 months. An average of 4.63 cycles of chemotherapy was administered. The median actual survival was 44 months, and the 1 and 3-year survival probabilities were 92% and 50%, respectively. The median disease-free survival was 15.5 months, and the 1 and 3-year disease-free survival probabilities were 66% and 28%, respectively. Only 5 (9%) and 1 (2%) patients had grades 3 and 4 leukopenia, respectively, and none died of sepsis. The use of adjuvant cisplatin, methotrexate and vinblastine chemotherapy in patients with invasive transitional cell carcinoma at high risk for recurrence is feasible with tolerable toxicity but randomized controlled trials will be required to assess the benefit.
