Objective: The objective was to analyze the outcomes of the patients, who received salvage radiotherapy for incidentally discovered cervical cancer following simple hysterectomy, and to identify the influence of intracavitary radiotherapy on treatment outcomes. Methods: Data from 117 patients with occult cervical cancer who underwent simple hysterectomy followed by salvage radiotherapy from September 1979 to November 2010 were collected. All the patients received external beam radiotherapy with (n = 45) or without (n = 72) intracavitary radiotherapy. Local control, disease-free survival, overall survival and treatment-related toxicity were investigated. Results: The median follow-up time was 75 months. The 5- and 10-year local control/diseasefree survival/overall survival rates were 93/87/87% and 90/84/83%, respectively. Among 98 patients who had no residual disease and negative resection margin on surgical specimens, 32 (33%) received intracavitary radiotherapy and 66 (67%) did not. There were no differences in patient and tumor characteristics between patients treated with and without intracavitary radiotherapy. The 5-year local control rate for the non-intracavitary radiotherapy group was 93 versus 94% for the intracavitary radiotherapy group (P = 0.564); the disease-free survival rate was 88 versus 94%(P = 0.894); the overall survival rate was 95 versus 85% (P = 0.106), respectively. Among all patients, there were 5% of Grade 3 or higher late toxicities. Conclusions: Patients with occult invasive cervical cancer discovered following simple hysterectomy could be treated safely and effectively with salvage radiotherapy. For patients with no residual disease and negative resection margin, intracavitary radiotherapy could be omitted.
