Purpose : To determine the role of pelvic irradiation in stage ¥° or ¥±A cervical
carcinoma with Pelvic nodal metastasis after hysterectomy and bilateral pelvic
lymphadenectomy.
Materials and Methods : This is a retrospective study of 68 cervical carcinoma
patients who were found to have pelvic nodal metastasis at hysterectomy and received
pelvic irradiation from 1983 to 1996 at Inje University seoul paid Hospital. External
beam radiation therapy to pelvis was delivered using 4 MeV Linac and intracavitary
irradiation was given via vaginal ovoids or cylinders. Five-rear survival and
disease-free survival were estimated by Kaplan-Meier Method and prognostic factors
related to survival were analysed by log-rank test and Cox proportional hazards
regression model.
Results : Median length of follow-up was 52months. Five-year overall survival and
disease-free survival (DFS) were 81.8% and 81.7% respectively. Patients with
endometrial invasion had a 57.1% 5-year DFS compared to 87.5% for those without
endometrial invasion (p=0.0074). Multivariate analysis revealed endometrial invasion as an
only statistically significant prognostic factor for 5-rear DFS. Among total 15 (22%)
recurrences, pelvic recurrences occcured in 4 cases and distant metastases occurred in
13 cases.
Conclusion : We have been able to confirm previous results demonstrating marked
decrease in local recurrence after pelvic irradiation. In view of the high proportion of
distant metastasis found in this study, a trial of aggressive adjuvant systemic therapy
and irradiation in early stage cervical carcinoma patients with pelvic nodal metastasis,
especially with endometrial invasion, appears to be warranted.
