Surgical treatment of brain metastases from lung cancer.
Thirty-five patients underwent surgical resection of brain metastases from non-oat-cell lung cancer between 1978 and 1981. Twenty-nine patients received postoperative radiation therapy to the brain. Twenty-three patients were male and 12 were female. Intracranial metastases occurred as the initial symptom of malignancy in 14 patients, and at varying periods following treatment of the primary tumor in 21 patients. The primary tumor and involved nodes were treated by definitive surgery in 18 patients, palliative resection and interstitial radiation in 10 patients, and by radiation therapy or chemotherapy alone in seven patients. The overall median survival time was 14 months. Favorable prognostic variables included: 1) absence of local or systemic disease at time of craniotomy (median 23 months survival time); 2) aggressive treatment of the primary tumor (median 18 months survival time); and 3) metachronous onset of brain metastases (median 15 months survival time). These survival data represent a considerable improvement over the historical 6 months median period of survival in such patients.
