Between 1972 and 1984, the Alexis Vautrin Center performed a post-hospital treatment for 123 cases of primary or recurrent tumors in the previously irradiated sites of the oropharynx and tongue. The initial irradiation dose for these patients was 36-140 Gy, with an average of 69 Gy; 72 relapsed tumors were relapsed and 51 were primary; 43 re-irradiated sites were flat crypts, 32 were tongue roots, and 26 were tongues. Body or tongue, 22 cases of soft palate. According to the UICC TNM staging, 35 patients had T_1, 49 patients had T_2, 38 patients had T_3, 1 patient had T_4, 82 patients had N_1, 32 patients had N_2, and 9 patients had N_3. During the course of radiotherapy with ~(192) helium, the procedure was followed by radiotherapy. Twenty-one patients were combined with external radiation. The total irradiation dose was 31-84 Gy with an average of 62 Gy; the dose rate was 8-16 Gy/day for 62%>16 Gy/day for 19% <8 Gy/day for 19%. The authors saw that for 2 years and 5 years The local control rates were 67% and 69%, respectively. The 2-year and 5-year survival rates were
