本文总结了非小细胞肺癌单纯放疗300例。男性224例、女性76例。年龄在28～78岁,41岁以上占97％。中心型179例,周围型121例。有病理或细胞学诊断者141例,放疗结果证明病理类型与存活率有关,鳞癌及腺癌5年生存率基本相同(5％),而大细胞癌均在1年内死亡。剂量与存活率有明显关系、小于49Gy均死于1年之内,60～70Gy以上者5年存活率为7.5～22％。肿块变化与存活率有一定关系、肿块发展者多在1年内左右死亡、而消失缩小或无变化者则对生存率影响不大。肿块无变化尚能长期生存者5例可能与放疗后肿瘤细胞静止而表现的自限作用有关。
This article summarizes 300 cases of non-small cell lung cancer radiotherapy alone. 224 males and 76 females. Ages range from 28 to 78, and over 97 years of age account for 97%. There were 179 cases of central type and 121 cases of peripheral type. There were 141 cases diagnosed by pathology or cytology. Radiotherapy results showed that the pathological type was related to the survival rate. The 5-year survival rate of squamous cell carcinoma and adenocarcinoma was almost the same (5%), while large cell carcinoma died within 1 year. There was a significant relationship between dose and survival rate, less than 49 Gy all died within 1 year, and 5-year survival rate was 60 to 70 Gy over 7.5 to 22%. There was a certain relationship between changes in the mass and the survival rate. The masses of the masses died within a year or so, but those who disappeared or had no changes had little effect on the survival rate. The 5 cases with no changes in the tumor but still able to survive for a long period of time may be related to the self-limiting effects of tumor cell quiescence after radiotherapy.
