Abstrakt     To contribute to the definition of the optimal total radiation dose and to determine the role of concurrent chemotherapy after macroscopically incomplete resection of squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS: Twenty-six patients treated with postoperative radio(chemo)therapy following macroscopically incomplete resection were evaluated. Total radiation dose (70 Gy vs. 59.4-66 Gy), concurrent chemotherapy (yes vs. no) plus six factors were investigated for locoregional control (LRC) and overall survival (OS). RESULTS: On analyses of LRC, 70 Gy was significantly superior to 59.4-66.0 Gy. Two-year LCR rates were 94% and 25%, respectively (p<0.001). Concurrent chemotherapy significantly improved 2-year LRC (90% vs. 0%, p<0.001). Both 70 Gy (92% vs. 11%, p<0.001) and concurrent chemotherapy (80% vs.0%, p<0.001) also resulted in better OS. CONCLUSION: A total radiation dose of 70 Gy was significantly superior to lower doses regarding both LCR and OS. Concurrent chemotherapy is also very important to achieve optimal outcomes.
