鼻咽癌 (NPC)远处转移是其死亡最常见的原因 ,如果能从临床角度来预测远处转移发生的可能性 ,对临床医生的治疗措施将提供重要的参考价值。笔者收集 1991～ 2 0 0 2年经随访 5年以上证实放疗后无复发转移的NPC患者 192例 ,放疗前已发生远处转移的 10 3例及放疗后在 1个月～ 10 The distant metastasis of nasopharyngeal carcinoma (NPC) is the most common cause of death. If we can predict the possibility of distant metastasis from the clinical point of view, the clinician’s treatment will provide important reference value. The author collected 192 cases of NPC patients with no recurrence and metastasis after 5 years of follow-up from 1991 to 2002. There were 103 cases of distant metastasis before radiotherapy and 1 month to 10 months after radiotherapy
