Abstract

The optimal treatment for patients with locally recurrent carcinomas of the salivary glands is unclear.Ninety-nine patients underwent salvage surgery for locally recurrent salivary gland carcinomas. Eighty-one (82%) had previously received radiation. Thirty-seven patients (37%) received intraoperative radiation therapy (IORT) to a median dose of 15 Gy (range, 12-18 Gy) at the time of salvage.The 1-, 3-, and 5-year estimates of local control after salvage surgery were 88%, 75%, and 69%, respectively. A Cox proportional hazard model identified positive margins (0.01) and the omission of IORT (p = .001) as independent predictors of local failure. The 5-year overall survival was 34%. Distant metastasis was the most common site of subsequent failure, occurring in 42% of patients.IORT significantly improves disease control for patients with locally recurrent carcinomas of the salivary glands. The high rate of distant metastasis emphasizes the need for effective systemic therapies.
