| Abstract: | Purpose: To report long-term outcomes of high-dose-rate (HDR) intraoperative radiotherapy (IORT) at the time of radical resection for recurrent head-and-neck cancer and determine potential prognostic factors. Methods and Materials: Between 7/1998 and 11/2011, 57 patients with recurrent head-and-neck cancer underwent radical resection with curative intent and single-fraction IORT to 59 sites using a Harrison-Anderson-Mick applicator with remotely after-loaded 192Ir HDR brachytherapy. Results: One- and 3-year in-field progression-free survival (IFPFS) was 67% and 57%, respectively. In a multivariate model, IORT dose >15. Gy (hazard ratio [HR] = 0.11; p = 0.02), and prerecurrence disease-free interval >12 months (HR = 0.29; p = 0.04) independently predicted for superior IFPFS; nodal extracapsular extension (HR = 4.62; p = 0.003) predicted for inferior IFPFS. Three-year overall survival (OS) was 50% vs. 32% in those achieving in-field control vs. those not achieving in-field control (. p = 0.04). Grade 3+ toxicity occurred in 37% and was unrelated to IORT dose. Conclusions: HDR-IORT combined with radical surgical resection is associated with durable IFPFS and long-term overall survival in select patients with acceptable treatment-related morbidity. IORT dose >15. Gy should be used to increase the likelihood of disease control. The ability to achieve in-field local control in this poor prognostic cohort was associated with improved survival outcomes. © 2013 American Brachytherapy Society. |
