Patterns of Regional Recurrence After Definitive Radiotherapy for Cervical Cancer

Most regional recurrences after definitive RT for cervical cancer include a component of marginal failure, usually immediately superior to the radiation field. These recurrences suggest a deficiency in target volume. Recurrences also occur in-field, suggesting a deficiency in dose. Developments in pretreatment staging, field delineation, dose escalation, and posttreatment surveillance may help to improve outcome in these patients.
