Background and purpose: To report our experience in treating recurrent salivary gland malignancies using concurrent chemotherapy and reirradiation. Materials and methods: Between 1986 and 2007, 14 patients with locoregionally recurrent salivary gland cancer underwent maximal surgical resection followed by adjuvant 5-fluorouracil and hydroxyureabased chemotherapy concurrently with 1.5 Gy twice daily or 2 Gy daily reirradiation; Each cycle consisted of chemoreirradiation for 5 consecutive days followed by a 9-day break. The median reirradiation dose was 66 Gy (R 30-72 Gy) after a mean radiation treatment interval of 48 months. Results: The median follow-up for all patients was 18 months (R 2-125 months) and 41 months for survivors. The parotid gland (n = 6) and minor salivary glands (n = 6) were involved more commonly than the submandibular gland (n = 2). Locoregional control at 1 and 3 years was 72.2% and 51.6%, respectively. Actuarial overall survival at 3 and 5 years was 35.7% and 26.8%, respectively. Tracheostomies and feeding tubes were placed in 2 and 8 patients, respectively. Six patients had feeding tubes at last follow-up or death. Conclusions: Concurrent chemotherapy and reirradiation for recurrent salivary malignancies result in promising locoregional control for patients with recurrent salivary gland malignancies.
