Materials and methods:Between April 1997 and February 2006, 236 patients with locally advanced, his-tologically proven, and new or recurrent cancer of the head and neck were treated with carbon ions. The treatment dose was 64.0 GyE/16 fractions/4 weeks(or 57.6 GyE/16 fractions/4 weeks when the wide-range skin was included in the target volume). Results: There were grade 3 acute skin reactions in 6% and grade 3 acute mucosal reactions in 10% with no acute reactions worse than grade 3, and grade 2 late skin reactions in 3% and grade 2 late mucosal reac-tions in 2% with no late reactions worse than grade 2.The 5-year local control rate, by histological type, was 75% for the 85 patients with malignant melanoma, 73% for the 69 with adenoid cystic carcinoma, 73% for the 27 with adenocarcinoma, 61% for the 13 with papillary adenocarcinoma, 61% for the 12 with squa-mous cell carcinoma and 24% for the 14 with sarcomas. The 5-year over-all survival rate was 68% for ade- noid cystic carcinoma, 56% for adenocarcinoma and 35% for malignant melanoma. Conclusions: Carbon ion radiotherapy for head and neck cancer showed the therapeutic effectivaness for malignant melanoma and adenoid cyatic carcinama without severe morbidity of the normal tissues.}, pages = {32--37}, title = {Results of carbon ion radiotherapy for head and neck cacer}, volume = {103}, year = {2012} }
