Combined etoposide, ifosfamide, and cisplatin in the treatment of patients with advanced thymoma and thymic carcinoma. A French experience.
BACKGROUND
The value of a nonanthracyclin regimen in thymic carcinoma and malignant thymoma is not well defined. These regimens may be useful in some patients, particularly with cardiac diseases. The objective of this study is to evaluate the response rate, progression free survival, overall survival and toxicity of combined etoposide, ifosfamide, and cisplatin in patients with advanced thymoma and thymic carcinoma.


METHODS
From October 1995 to April 2001, 18 patients with advanced thymoma or thymic carcinoma were entered on trial, and receive etoposide (100 mg/m(2) on days 1-3), ifosfamide (1500 mg/m(2) on days 1-3), s and cisplatin (30 mg/m(2) on days 1-3). Cycles were repeated every 3 weeks for a total of six cycles.


RESULTS
Among 16 evaluable patients, there were no complete responses and four partial responses (complete and partial responses rate, 25%; confidence interval [CI] 95, 7-48%). The median follow-up was 32.6 months (range, <9-84 months), and the median overall survival has not yet been reached because more than 50% of patients are still alive. Based on Kaplan-Meier estimates, the 1-year and 2-year survival rates were 93.8 and 78.1%, respectively. The toxicity was predominantly myelosuppresion and alopecia.


CONCLUSIONS
The combined etoposide, ifosfamide, and cisplatin regimen has moderate activity in patients with advanced thymic tumors. Our results confirm the Eastern Cooperative Oncology Group trial published in 2001. Response rates appear to be lower to many phase II trials, but survival seems similar.
