Abstract
Twenty-two previously untreated patients with adenocarcinoma of the ovary were treated with 28 day cycles of hexamethylmelamine, Adriamycin (doxorubicin), and cisplatin (HAC) for 9 months followed by three monthly cycles of intense intravenous cyclophosphamide. An overall response frequency of 82% (18/22) was achieved. Complete pathologic responses (CPR) documented by second look operations were found in 50% (11/22); however, patients considered to be free of disease (prolonged complete clinical response refusing “second look” and CPR) totaled 59%. Median survival has not been reached after a median follow-up of 34 months. No major or life threatening toxicity was encountered. HAC followed by cyclophosphamide is a highly effective regimen that may be easily administered on an outpatient basis with comparatively little toxicity.
