局限期小细胞肺癌（ＬＳＳＣＬＣ）全脑预防照射可降低脑转移率，但并未提高生存率。回顾性分析１９８９年１０月～１９９４年１月在我科治疗的ＬＳＳＣＬＣ达完全缓解（ＣＲ）的８０例患者，其中行脑预防照射３２例，未行脑预防照射４８例，以探讨脑预防照射的适应证。对象与
Localized small cell lung cancer (LSSCLC) prevention of whole brain irradiation can reduce the rate of brain metastases but does not improve survival. We retrospectively analyzed 80 patients with complete remission (CR) in LSSCLC treated in our department from October 1989 to January 1994. Among them, 32 patients underwent cerebral prophylaxis and 48 underwent brain irradiation to explore brain irradiation prevention. Indications. Objects and
