Mitomycin C adjuvant chemotherapy after Wertheim's hysterectomy for stage IB cervical cancer.

Patients undergoing radical surgical treatment for Stage IB and IIA cervical carcinoma are at high risk of developing local recurrence and/or distant metastases when one or more of the following factors are present: presence of metastatic pelvic lymph nodes, a large primary growth, full-thickness tumor invasion of the cervix, clinically undetected parametrial extension, and lymphatic/vascular channel permeation in the cervix by tumor cells. Carcinoma of the cervix appears to be behaving like a systemic disease. Therefore, systemic measures should be considered in its therapy. The authors report the initial experience with the use of mitomycin C as a single agent adjuvant in 16 patients with Stage IB carcinoma of the cervix who had undergone Wertheim radical hysterectomy and were thought to be in this high-risk group. Fourteen of the patients are alive and free of disease after durations of follow-up ranging from 16 to 38 months, the disease-free survival at a median follow-up of 29 months being 87.5%. One patient required discontinuation of adjuvant chemotherapy because of severe marrow toxicity; however, in view of the presence of a multiple risk factors, pelvic irradiation was given instead. She died 13 months later from disseminated disease. A second patient died 6 months later from congestive cardiac failure.
