Elderly ovarian cancer: Treatment with mitoxantrone-carboplatin

Objective. Data concerning optimal treatment of elderly patients with ovari an cancer are scanty. The management of ovarian cancer in the aged patient is many-sided: the diagnosis can be difficult and delayed, and aggressive s urgery is often not attempted because of concomitant morbidity. We tested a combination of carboplatin and mitoxantrone potentially associated with lo w toxicity in elderly patients with ovarian cancer. Methods. Eighty-two patients older than 70 years (median age, 75; range, 70 -88) with epithelial ovarian cancer were referred to our multicenter group and enrolled into this pilot study. Carboplatin (JM8) was given at the dose of 230 mg/m(2) and mitoxantrone at the dose of 9 mg/m(2) every 28 days. Results. Dose-limiting toxicity was represented by 4 cases of thrombocytope nia and 1 case of gastrointestinal toxicity. These 5 episodes occurred in 3 28 assessable cycles, representing a low toxicity profile (3%). Of the 68 a ssessable patients, 36 (53%) did not respond to chemotherapy (no change + p rogressive disease), complete response was observed in 15 (22%), and partia l remission was observed in 16 (23.5%), accounting for an overall response rate of 45%. Conclusion. The carboplatin-mitoxantrone combination, at the dosage tested in this study, appears to be well tolerated by elderly patients with advanc ed ovarian cancer and is associated with an acceptable response rate. Optim ally debulked patients also showed improved survival when compared with pat ients with more extensive tumor. (C) 2001 Academic Press.
