Single brain metastasis of non-small cell lung carcinoma. Study of survival among 54 patients.

We studied 54 patients treated for non-small cell lung carcinoma with single brain metastasis presenting between 1980 and 1985. Better survival was obtained in cases of patients presenting a fair neurological condition who were treated by surgery. Histological condition and date of onet of metastasis had no significant influence on survival. Combined treatment of both primary lung tumour and brain metastasis was a favourable prognosis element, and surgical resection of both locations led to the best results in terms of duration and quality of survival.
