Abstract

Objective: To evaluate the effect of resection of central disease when the parametria are involved by tumor in high-risk stage I cervical cancer patients. Methods: Thirty-two patients with high-risk stage I cervical cancer who underwent radical hysterectomy and had pathologic findings of positive lymph nodes (N = 13), positive parametria (N = 7), or both (N = 12) were identified retrospectively. The effects of various histopathologic findings on disease-free interval and survival were evaluated, including the effect of resection of central disease with and without positive nodal disease. Kaplan- Meier survival curves were compared with the log-rank test. Multivariate analyses using a stepwise regression model were performed. Results: Compared with other histologies, adenocarcinoma was associated with a significantly shorter disease-free interval (P = .037). Among patients with parametrial involvement, lymph node status did not affect disease-free interval or survival. However, when patients with positive lymph nodes were examined, the additional finding of parametrial positivity significantly worsened both disease-free interval (P = .039) and survival (P = .036). When the 19 patients with positive parametria, regardless of lymph node status, were compared with those with positive lymph nodes alone, the former group had a significantly shorter disease-free interval (P = .038). The tumor recurred in 12 of these 19 patients; all cases involved the pelvis, with a median time to recurrence of 15 months. Multivariate analysis showed that adenocarcinoma histology (P = .038) and parametrial involvement (P = .043) were independent, poor prognostic indicators for disease-free interval. Conclusion: Involvement of the parametria, regardless of lymph node status, and adenocarcinoma histology confer a poor prognosis in high-risk patients undergoing radical hysterectomy. Caution should be used when contemplating resection of bulky tumors as part of primary therapy if the parametria appear to be involved by tumor.
