Abstract
From November 1973 to May 1986, 50 patients with Stage I epithelial ovarian cancer were treated at the University of Kentucky Medical Center (Lexington, KY) with oral Alkeran (melphalan) chemotherapy after primary surgery. Twenty-two patients had Grade 1 tumors, 23 patients had Grade 2 tumors, and five patients had Grade 3 tumors. Patients with ovarian tumors of borderline malignancy were excluded from this study. Twenty-eight patients received from six to 11 courses of chemotherapy and 22 patients completed 12 courses of chemotherapy. Chemotherapy was well tolerated and no patient died of chemotherapy-related complications. Thirty-eight patients underwent second-look laparotomy and one was positive. The patient with persistent ovarian cancer at second-look laparotomy died of disease 41 months after diagnosis and one patient died with no evidence of disease 6 months after treatment. The actuarial survival of the total group of patients was 98% at 2 years and 94% at 5 years. Fewer than 12 months of chemotherapy may be necessary to obtain long-term survival in these patients.
