Management of nonsmall cell lung carcinoma with solitary brain metastasis

Cushing's group, operating on metastatic brain tumors in the 1920s, was the first to point out that lung cancer (usually adenocarcinoma in an upper lobe) was the most common primary tumor. Excision of a solitary metastasis could result in long-term survival. Magilligan and coworkers (J Thorac Cardiovasc Surg 1976;72:690) introduced the modern era of large series of combined lung-brain resection with low mortality (3%) and a 5-year outcome of 21%. Our results (92 patients) confirm their experience. Presenting symptoms were pulmonary (53), synchronous (28), or neurologic (11). Nonsquamous cell (48) predominated. Pulmonary resections (45) were pneumonectomy (five), lobectomy (27), segmentectomy (five), and wedge biopsy (eight). Craniotomy (68) and irradiation resulted in recurrence in seven patients. There was no operative mortality. The survival rate after curative lung and brain resection (27) was 52% at 1 year, 35% at 2 years, and 21% at 5 years. Median survival in noncurative combined resection (eight), craniotomy only (27), thoracotomy only (eight), or no surgery (22) groups, with or without irradiation or chemotherapy, averaged 6.4 months. Every effort should be made to give patients with this syndrome the benefit of combined surgery, which was not offered or agreed on in more than a third of our cases.
