Abstract

Background/Purpose: Patients with locally recurrent or persistent high-risk neuroblastoma are difficult to treat. We describe our experience using intraoperative radiation therapy (IORT) after re-resection in this high-risk population. Methods: We retrospectively reviewed 44 consecutive patients who received IORT at our institution between April 2000 and September 2009 after gross total resection of recurrent/persistent tumor. Specifically, we evaluated local recurrence rates, complications, and overall survival. Results: The median age at diagnosis was 41.5 months. Median follow-up after IORT was 10.5 months. Each patient received prior chemotherapy and surgery, while 94.5% had previous external beam radiation therapy. MYCN was amplified in 34% of patients. There were no operative or postoperative deaths, and 18 patients (40.9%) had postoperative complications. There was a 50.4% probability of local control. MYCN amplification did not affect local control (local recurrence rate of 53.9% vs 52.4%, P = .89). Median overall survival was 18.7 months (95% confidence interval, 11.7-25.6 months). Mean survival for MYCN-amplified patients was 13.0 vs 39.2 months for those without MYCN amplification (P = .035). Conclusions: Intraoperative radiation therapy after re-resection of locally recurrent/persistent neuroblastoma results in a reasonable rate of local control with acceptable morbidity and survival. This approach should be considered in this high-risk population.
