内容記述 | Purpose/Objective(s) To estimate the toxicity and efficacy of carbon ion radiotherapy for adenocarcinoma of the head-and-neck. Materials/Methods Between April 1997 and February 2012, a total of 50 patients with adenocarcinoma of the head-and-neck were treated with carbon ion radiotherapy. None of these patients had either regional lymph node or distant metastasis before radiotherapy.The prescribed tumor doses were 57.6 or 64.0 GyE in 16 fractions over four weeks. All patients provided written informed consent before enrollment in this study. The National Institute of Radiological Sciences Ethical Committee on Human Clinical Research has approved this study. Results The patients consisted of 29 males and 21 females aged from 26 to 80 years with an average age of 61 years. As for the tumor sites studied, there were 15 paranasal sinus, 9 orbit, 7 nasal cavity, 7 major salivary gland, 5 pharynx, 4 oral cavity, 2 external ear canal and 1 parapharyngeal space. Forty-one of 50 patients with unresectable tumors or with recurrence and residual tumors after other treatment were permitted to partake in the carbon ion radiotherapy. The gross tumor volume ranged from 1.8 to 227.7 ml, with an average of 67.2 ml.Median follow-up time was 42.5 months (range, 3.9-179.8 months). Although acute grade 3 skin and mucosal reactions appeared in 2 of 50 patients (4%) and 8 of 45 patients (18%), almost all of the late skin and mucosal reactions were grade 1 or less. At the time of analysis, there was no evidence of any unexpected severe toxicity to the critical organs. The 5-year local control and overall survival rates of all patients were 83% and 55%, respectively. As for the T stage studied, the 5-year local control rates were 88% for stage from T1 to T3, 74% for T4 and 88% for recurrence and residual tumors after other treatment. The 5-year overall survival rates were 88% for stage from T1 to T3, 42% for T4 and 54% for recurrence and residual tumors after other treatment, respectively. Conclusions Our results showed acceptable toxicities and excellent therapeutic effectiveness for adenocarcinomas. |
