High-risk group in node-positive patients with stage IB, IIA, and IIB cervical carcinoma after radical hysterectomy and postoperative pelvic irradiation.
OBJECTIVE
The goal of this study was to identify risk factors in patients with node-positive stage IB, IIA, and IIB cervical carcinoma after radical hysterectomy with pelvic lymph node dissection and postoperative irradiation.


METHODS
Two hundred forty-two patients with FIGO stage IB, IIA, and IIB cervical carcinoma underwent radical hysterectomy with pelvic lymph node dissection; pathological analysis of the surgical specimen showed positive lymph nodes in 59 patients. These 59 patients were further treated with postoperative radiotherapy. Eighteen patients were in stage IB, 4 in stage IIA, and 37 in stage IIB. Histological tumor type, tumor size, lymph-vascular space invasion, parametrium infiltration, number of positive nodes, and involvement of common iliac nodes were assessed for correlation with cancer recurrence.


RESULTS
When all these variables were assessed in the Cox proportional regression analysis, parametrium infiltration (P = 0. 0199) and number of positive nodes (two or more nodes) (P = 0.0483) revealed the factor correlating significantly with disease-specific survival. Based on these two factors, node-positive patients could be divided into low-risk (n = 11), intermediate-risk (n = 29), and high-risk (n = 19) groups. The 5-year disease-specific survival for the low-risk group was 100% which was significantly better than the 39.1% for the high-risk group (P = 0.0012).


CONCLUSIONS
For patients in the high-risk group, it may be worthwhile to consider new strategies to improve survival.
