PURPOSE: To evaluate outcome of radiotherapy for locally recurrent cervical and endometrial cancer. MATERIALS AND METHODS: Nineteen patients were treated for a locally recurrent cervical (n=12) or endometrial (n=7) cancer median 26 months after initial surgery (n=18) or radiotherapy (n=1). The whole pelvis was irradiated with 50Gy conventionally fractionated radiotherapy (n=16). Because of large size of the recurrent cancer (median 4.5 cm) and peripheral location (n=12), stereotactic body radiotherapy (SBRT; median 3 fractions of 5Gy to 65%) was used for local dose escalation instead of (n=16) or combined with (n=3) vaginal brachytherapy. RESULTS: After median follow-up of 22 months, 3-year overall survival was 34% with systemic progression the leading cause of death (7/10). Median time to systemic progression was 16 months. Three local recurrences resulted in a local control rate of 81% at 3 years. No correlation between survival, systemic or local control and any patient or treatment characteristic was observed. The rate of late toxicity>grade II was 25% at 3 years: two patients developed a grade IV intestino-vaginal fistula and one patient suffered from a grade IV small bowel ileus. CONCLUSION: Image-guided SBRT for local dose escalation resulted in high rates of local control but was associated with significant late toxicity. Copyright 2009 Elsevier Ireland Ltd.
