摘要
目的分析鼻咽癌放射治疗后肿瘤残留对生存率的影响。方法回顾性分析304例经病理证实并接受根治性放射治疗的鼻咽癌患者鼻咽部及颈部肿瘤残留情况,记录残留灶的大小。108例有残留者中单纯鼻咽残留26例,单纯颈部残留68例,两者均有残留14例。结果鼻咽癌放射治疗后有残留者较无残留者的1、3、5、10年生存率低。单纯鼻咽残留者生存率最高,单纯颈部残留者其次,两者均有残留者最低。颈部残留灶越大,生存率越低。有残留者的局部复发率增高。结论鼻咽癌放射治疗后有残留者的生存率下降,尤其是颈淋巴结及鼻咽均有残留者。放射治疗后肿瘤残留可作为判断预后的一个指标。
Objective To observe the effect of residual tumor after radiotherapy on survival rate of patients with nasopharyngeal carcinoma (NPC). Methods From Jan. 1989 to Dec. 1998, 108 of 304 NPC patients pathologically confirmed, had residual tumor after radical radiotherapy, of whom, 26, 68, 14 had residual lesion in the nasopharyngeal cavity alone, cervical lymph node alone, and nasopharyngeal cavity plus cervical lymph node. Results The overall 1 , 3 , 5 , and 10 year survival rates (OS) significantly decreased in the residual group. The highest OS was in the group with nasopharynx residual alone, and the lowest in nasopharynx plus residual lymph node group. The bigger the residual lesion, the lower the OS. Conclusions The overall survival rate decreases in patients with residual lesion after radiotherapy, especially in patients with both nasophrynx and regional lymph node residual. Tumor residual after radiotherapy can be a prognostic indicator for patients with NPC.
