Abstract

Background.

The optimal treatment for patients with locally recurrent carcinomas of the salivary glands is unclear.

Methods.

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.

Results.

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.

Conclusions.

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. © 2007 Wiley Periodicals, Inc. Head Neck, 2008
