Purpose:
This study investigated the prognostic significance of age, stage, tumor size, pelvic lymph node metastasis (PLM), surgical margin invasion, overall radiotherapy time (ORT), and interval between radiotherapy and surgery (IRS) in stage IB-IIA cervical carcinoma.
Method And Materials:
100 patients treated with radical hysterectomy and postoperative radiotherapy were evaluated retrospectively.
Results:
The 5-yr overall survival (OS), disease-free survival (DFS), and pelvic control rate (PC) were 83.6%, 82.8%, and 91.8%, respectively. PLM (p=0.008), IRS (p=0.01), ORT (p=0.007), and tumor size (p=0.028) were found to be significant on PC. PLM (p=0.04), ORT (p=0.04), and IRS (p=0.001) were significant on OS. PLM was significant (p=0.04) and IRS was marginally significant (p=0.06) on DFS. After multivariate analysis, PLM was significant on OS, DFS and PC. Recurrences were seen in 14 patients.
Conclusion:
According to this study PLM, IRS, and ORT are the most important prognostic factors. Recurrences outside the radiation volume leads to treatment failure.
