Abstract

BACKGROUND

Accelerated fractionation radiotherapy (RT) was administered in an attempt to improve the local control rates in patients with T1/T2 N0 glottic cancer.

METHODS

Medical charts of 148 consecutive patients who had undergone RT using 2.4 Gray (Gy) once-daily fractionation between July 1999 and April 2007 were reviewed.

RESULTS

Of 104 patients with T1 disease treated by RT, 82 received 60 Gy/25 fractions, and the remaining 22 with large tumor volumes and/or slow response to RT received 64.8 Gy/27 fractions. All 44 patients with T2 disease received 64.8 Gy/27 fractions. The 5-year local control and overall survival (OS) rates were 93% and 96%, respectively, in patients with T1 disease, and 77% and 91%, respectively, in patients with T2 disease. No severe acute toxicities were observed, although 2 patients (1%) developed severe late toxicity.

CONCLUSION

Accelerated RT for early glottic cancer is feasible, with encouraging local control rates.

摘要

背景

采用加速分割放射治疗（RT）以试图提高T1/T2 N0声门癌患者的局部控制率。

方法

回顾了1999年7月至2007年4月期间连续148例接受2.4格雷（Gy）每日一次分割放疗的患者的病历。

结果

在104例接受放疗的T1期疾病患者中，82例接受60 Gy/25次分割，其余22例肿瘤体积大且/或对放疗反应缓慢的患者接受64.8 Gy/27次分割。所有44例T2期疾病患者均接受64.8 Gy/27次分割。T1期疾病患者的5年局部控制率和总生存率（OS）分别为93%和96%，T2期疾病患者分别为77%和91%。未观察到严重的急性毒性反应，尽管有2例患者（1%）出现严重的晚期毒性反应。
