Between May 1990 and February 1995, 16 patients with adenocarcinoma or adenosquamous carcinoma of the uterine cervix were prescribed neoadjuvant chemotherapy consisting of cisplatin (50 mg/m2) on day 1, mitomycin C (10 mg/m2) on day 1, and etoposide (100 mg/m2) on days 1, 3, and 5 (MEP). In 2 patients stage was IB1, 5 were in stage IB2, 1 was in stage IIA, 5 were in stage IIB, 2 were in stage IIIB, and one was in stage IVB. A median of three courses of chemotherapy was given (range two to five). Of the 16 patients, 3 had a complete response and 5 had a partial response (response rate, 50%). Following termination of this chemotherapy, 12 patients with stage I or stage II carcinoma underwent radical hysterectomy. Three were given adjuvant radiotherapy because of positive pelvic nodes. One stage IIB patient, 1 stage IIIB patient and 1 stage IVB patient underwent standard radiotherapy and 1 stage IIIB patient underwent chemotherapy with another regimen because MEP therapy was without effect. Histopathological examinations revealed that changes as a result of the chemotherapy correlated well with clinical responses. Moderate or marked pathological changes occurred in 3 with a clinically complete response. The mean survival period of responders was 47.5 months while that of nonresponders was 28.3 months. Side effects of chemotherapy with MEP were within acceptable limits. The dose-limiting toxicity was myelosuppression and for only 1 patient the dose was reduced because of thrombocytopenia. Our preliminary study indicates that this chemotherapy regimen is effective for subjects with adenocarcinoma of the cervix. A prospective cooperative group trial on this regimen is ongoing.
