PURPOSE: To determine the prognostic impact of cervical size and pelvic lymph node status assessed by computed tomography (CT) in uterine cervical carcinoma treated with irradiation alone. METHODS AND MATERIALS: Seventy patients with International Federation of Gynecology and Obstetrics (FIGO) Stage IIB and IIIB uterine cervical squamous cell carcinoma treated with a combination of external and high dose-rate intracavitary irradiation were entered into analyses. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. RESULTS: There were no significant differences in pelvic control rate (PC), distant metastases-free rate (DMF), cause-specific disease-free survival rate (CSDFS) among subgroups with cervix < 60 mm in diameter. However, PC (p = 0.023), DMF (p = 0.000025), and CSDFS (p = 0.0023) were significantly lower for patients with cervix > or = 60 mm than < 60 mm. The 5-year CSDFS was 77.5% for < 60 mm, and 28.6% for > or = 60 mm. Pelvic node status assessed by CT scans had significant prognostic impact on outcome. the 5-year CSDFS rate was 84.9% for patients with no enlarged nodes, and 58.9% for those with enlarged nodes greater than 1 cm in minimum diameter (p = 0.023). Whereas PC was not significantly affected, the DMF was strongly correlated with nodal status (p = 0.00027). Pelvic node status was taken as an independent predictor for DMF (p = 0.019) on multivariate analysis. CONCLUSION: Although cervical size assessed by CT had limited prognostic value, pelvic node status assessed by CT is the significant prognostic factor for patients with uterine cervical carcinoma treated with radical irradiation.
