The EORTC Gynaecological Cancer Cooperative Group conducted a phase II study of high dose oral megestrol acetate: 800 mg/day for 1 month followed by 400 mg/day as maintenance treatment, in heavily pretreated patients with ovarian cancer. Of 72 patients included in this study, 54 were fully evaluable for response and toxicity. The response rate was low with only 1 patient having a partial reponse, 9 patients with stable disease and 44 patients with progressive disease. The toxicity profile was low. However, 1 patient died after 2 months of treatment, and in 3 patients thrombo-embolic events occurred. Weight gain varied in 20 of the 61 patients from 0.5 to 16 kg. This study does not suggest that the overall 10% benefit from hormonal therapy for chemotherapy refractory ovarian cancer will improve by increasing the dose.
