我院放疗科1985年收治196例鼻咽癌,其中颈淋巴结转移167例。本文对经首程根治性放疗后颈淋巴结残留的有关因素进行了分析。指出临床分期N_(1—3)与颈淋巴结残留率有明显的正相关(P<0.001),强调早诊早治的重要性;对<5cm的淋巴结,合适的剂量是60Gy左右;增加剂量照射,未能减少残留和提高局部控制率;对经观察不消退的结节应优先考虑手术切除,可避免半数以上加量照射的盲目性。 本组颈淋巴结总的近期控制率是85.63％(137/160),未控23例。
In 1985, Radiotherapy Department of our hospital treated 196 cases of nasopharyngeal carcinoma, of which 167 cases had cervical lymph node metastasis. This article analyzes the related factors of residual cervical lymph nodes after radical radiotherapy for the first time. It was pointed out that clinical stage N_(1-3) had a significant positive correlation with cervical lymph node residual rate (P<0.001), emphasizing the importance of early diagnosis and early treatment; for <5cm lymph nodes, the appropriate dose was about 60Gy; increased dose irradiation , Failed to reduce residue and increase local control rate; for the nodule that was observed to be regressed, surgical resection should be given priority, and the blindness of more than half of the amount of irradiation could be avoided. The overall short-term control rate of this group of cervical lymph nodes was 85.63% (137/160), and 23 cases were not controlled.
