作者在10年间(1970～1980)共放射治疗鼻咽癌病人107例,大部分(87％)为Ⅳ期患者。治疗后发生远地转移者18例,其中50％的远地转移发生在放疗后6个月之内,94％在2年之内。出现远地转移后,病人平均生存期为6个月。在分析这些远地转移病例时,发现其决定性的影响因素是放疗前颈部转移淋巴结的大小,无肿大淋巴结或转移淋巴结小于直径3cm者,远地转移率低(10％);淋巴结3～6cm者,为25％;
In 10 years (1970 ~ 1980), a total of 107 cases of nasopharyngeal carcinoma patients were treated with radiotherapy. Most of them (87%) were stage IV patients. Eighteen patients had distant metastasis after treatment, of which 50% of distant metastases occurred within 6 months after radiotherapy and 94% within 2 years. After the distant metastasis, the average survival of patients was 6 months. In the analysis of these cases of distant metastasis, we found that the decisive factor is the size of lymph node metastasis before radiotherapy. No lymph node or lymph node metastasis less than 3cm in diameter, distant metastasis rate is low (10%); lymph node 3 ~ 6cm, 25%;
