Analysis of factors contributing to treatment failures in stages IB and IIA carcinoma of the cervix.

Between April, 1971, and September, 1977, 98 patients with Stages IB and IIA cervical cancer who underwent surgical exploration prior to treatment at Hershey Medical Center were studied. Those who had bulky primary tumor (greater than or equal to 4 cm) had a higher incidence of nodal metastases (80% vs. 16%), local recurrences (40% vs. 5%), and distant metastases (40% vs. 1%). Patients who had positive nodes had more local recurrences (24% vs. 6%) and distant metastases (28% vs. 0%). Those with grossly positive nodes had more distant metastases (60% vs. 7%) than those with microscopically positive nodes. Those who had positive nodes, vascular invasion, and/or deep invasion of the cervix (greater than or equal to 70% of thickness) in the radical hysterectomy specimen had more nodal metastases and local recurrences. Postoperative radiation seemed to prevent local recurrences (40% vs. 6%) and improve the 2-year tumor-free survival rate (94% vs. 55%). Patients who had bulky primary tumors and/or grossly positive nodes at laparatomy may require systemic therapy in view of the high incidence of distant failures.
