Abstract

Forty-eight patients with FIGO stage IVA cervix cancer were treated with radiation therapy at the Hunter Radiation Therapy Center, Yale--New Haven Hospital from 1966 to 1985. Nine of the 48 patients are alive without recurrence (NED) and the 5-year actuarial survival rate is 18% (+/- 6%, standard error). There was a substantial difference in outcome based on treatment technique. Thirty-five patients were treated with external beam (EB) plus intracavitary (IC) and 8 of these patients (23%) are NED. None of the 12 patients treated with EB alone are alive. One patient treated with preoperative EB plus exenteration is NED. The severe complication rate was 22% and most complications were vesicovaginal fistulas due to successful treatment for bladder involvement. There was a significant difference in survival for patients with minimal parametrial disease (stage IVA1) versus patients with significant parametrial disease (stage IVA2) which was defined as fixation to one or both pelvic sidewalls or hydronephrosis on IVP. The 5-year survival for stage IVA1 disease was 46% (+/- 14%) versus only 5% (+/- 4%) for stage IVA2 disease. Our results indicate that superior survival for stage IVA cervix cancer patients is associated with two factors: minimal parametrial disease and radiation treatment which combines EB plus IC.
