BACKGROUND The purpose of this study was to investigate pretreatment variables that could predict prognosis and to evaluate the impact of postoperative adjuvant therapy on the outcomes of patients with Stage IB or II cervical carcinoma with or without pelvic lymph node metastases. METHODS Eight hundred ninety‐one patients with Stage IB or II cervical carcinoma who underwent radical hysterectomy and bilateral pelvic lymphadenectomy as primary treatment at a single institution were analyzed. Potential prognostic variables were studied. RESULTS Among the variables that could be assessed before treatment, depth of cervical stromal invasion (determined by magnetic resonance imaging), clinical stage, tumor size, grade of differentiation, and DNA index (determined by flow cytometry) were independent predictors of outcome in multivariate analysis using a Cox regression model. Three distinct prognostic groups (low, intermediate, and high risk) were defined using these variables. Five‐year recurrence free survival (RFS) rates for the low, intermediate, and high risk groups were 94.6%, 82.7%, and 62.3%, respectively (P = 0.0001), and overall survival (OS) rates were 98.4%, 84.5%, and 68.7%, respectively (P = 0.0001). Among patients with pelvic lymph node metastases who were free of parametrial extension, those who received postoperative chemotherapy or chemoradiotherapy had significantly better RFS (P = 0.017) and OS (P = 0.043) than those who received no adjuvant therapy. Among patients without pelvic lymph node metastases but at high risk of recurrence, those who received adjuvant radiotherapy had significantly better RFS (P = 0.015) and marginally improved OS (P = 0.087) compared with those who received no adjuvant therapy. CONCLUSIONS A model containing assessable pretreatment variables for predicting the prognoses of patients with early stage cervical carcinoma was formulated. Subsets of patients for whom postoperative chemotherapy or radiotherapy might be beneficial were identified. The data from this retrospective review may be useful when future prospective trials of the treatment of early stage cervical carcinoma are designed.
