摘要
1990年3月至1991年8月,40例鼻咽癌随机分组为低氧照射组和照射组各20例。两组鼻咽与颈部照射D_T68～72Gy,5次/周,2Gy/次。低氧组在吸入10.5％氧气2分钟后照射,3分钟结束。两组肿瘤消退剂量、疗后复发、白细胞变化无差异,但出现口干、咽癌距首次放疗时间和口腔粘膜反应,低氧组比对照组晚,程度轻,说明低氧放疗对口腔粘膜有保护作用。
From March 1990 to August 1991, 40 NPC patients were randomized into hypoxyradiotherapy group (20 patients) and radiotherapy alone group (20 patients). For radiotherapy, 68-72 Gy was delivered to the nasopharynx and the bilateral neck regions, 2 Gy per session, 5 sessions per week. For hypoxia, 10.5% oxygen inhalation was started before and lasted to 3 minutes after radiation. The results showed the complete response, recurrence and WBC change were similar in the two groups. Yet, xerostomia, sore throat, mucosal reaction appeared late and were milder in the hypoxyradiotherapy group. The authors believe that hypoxic inhalation may be protective to the oral structures.
