Objective: The aim of this study was to evaluate the results of modified radical hysterectomy in the treatment of early cervical cancer.
Material and methods: A retrospective chart review of 56 patients with stage I (IA in 35, IB in 21) squamous cervical carcinoma treated with modified radical hysterectomy and followed for a minimum of 5 years (mean, 12 years; range, 5.1-29) was conducted. All pathology slides were reviewed for tumor size, grade, depth of invasion, and lymph-vascular permeation.
Results: The mean depth of invasion was 0.5 cm (range, 0.1-2.5 cm), and the mean tumor size was 1.1 cm (range, 0.1-7 cm). Only 3 patients (5.4%) had positive nodes. None of the patients with tumors 2 cm or less in size had positive nodes, whereas 33.3% of the patients with tumors more than 2 cm in size had positive nodes. A recurrence developed in 2 patients (5-year recurrence rate of 3.6%). There were 10 deaths during the entire follow-up period, but only 2 were related to cervical cancer. The disease-specific and overall 5-year survival rates were 96.4 and 94.6%, respectively. The disease-specific 5-year survival rate was 100% among the 47 patients with tumors 2 cm or less and 75% for the 9 patients with tumors larger than 2 cm. Univariate analysis identified stage, lymph node status, and tumor size as statistically significant prognostic factors for overall survival. Tumor grade, lymph-vascular permeation, and depth of invasion (1-3 mm vs >3 mm) were not statistically significant for overall survival.
Conclusions: Modified radical hysterectomy appears to be effective surgical therapy for patients with squamous cervical carcinoma 2 cm or less in size.
