title: Solitary brain metastases from non-oat cell lung cancer: clinical and prognostic features.
abstract: The authors report 91 cases of solitary brain metastasis from non-oat cell lung cancer, 66 patients were males and 25 females; average age was 57 years (range 40-72 years). Surgical removal was total in 80 cases and partial in 11. All patients received postoperative radiotherapy and 40 chemotherapy. Histologically, the tumor was an adenocarcinoma in 51 cases (56%), a squamous cell carcinoma in 22 (24%), an undifferentiated carcinoma in 18 (20%). Median survival was 16 months and the main cause of death was progression of the primary cancer (59% of cases). Survival was influenced by staging of the primary tumor, while no prognostic significance was found regarding the type of clinical tumor onset, type of radiotherapy and the histotype of the lesion. Use of the "no internal touch" technique and brain radiotherapy reduced local brain relapse.
