Post-hysterectomy radiotherapy in FIGO stage IB-IIB uterine cervical carcinoma.
OBJECTIVE
This study is a retrospective analysis of stage IB-IIB cervical carcinoma patients who had received postoperative radiotherapy (PORT).


METHODS
Eight hundred patients with stage IB-IIB cervical carcinomas who received PORT after radical hysterectomy and bilateral pelvic lymph node dissection (PLND) between February 1979 and March 2000 were analyzed.


RESULTS
The median follow-up duration was 100 months. The 5-year overall survival (OS) and disease-free survival (DFS) rates were 88% and 81%, respectively. One hundred forty-six patients (18%) failed, and 103 of these had distant metastases. Multivariate analysis revealed that pelvic lymph node (LN) metastasis significantly compromised OS, DFS, pelvic failure-free survival (PFFS), and distant failure-free survival (DFFS) (P < 0.05). Patients with age <50 years, deep stromal invasion (DSI), and lymphovascular space invasion (LVSI) were significantly associated with a higher risk of distant metastasis after PORT. The incidences of late rectal, urinary, and small bowel complications of grade 3 or higher were 1.6%, 1.4%, and 1.0%, respectively.


CONCLUSIONS
PORT achieved good OS and DFS in the patients with risk factors after radical hysterectomy for stage IB-IIB cervical carcinomas. Distant metastasis was the major pattern of treatment failure after PORT. Effective systemic chemotherapy might be a breakthrough in improving the outcome of PORT in patients with cervical carcinomas.
