- BACKGROUND: The aim of the current study was to determine whether a pulmonary resection and gamma-knife radiosurgery (GKRS) protocol is superior to GKRS alone in selected patients with stage IV nonsmall-cell lung cancer (NSCLC). METHODS: The authors performed a retrospective case-control study of 232 consecutive patients with newly diagnosed NSCLC from January 1998 to December 2005 and screened them to identify a study cohort in which all patients had thoracic stage I or II, Karnofsky performance status >or= 70, no extracranial metastases, and 1-3 synchronous brain metastases of less than 3 cm, and were treated with GKRS (n=31). The study cohort was divided into 2 groups, those with and without concomitant pulmonary resection. RESULTS: Sixteen patients with pulmonary resection were assigned to the treatment group and 15 without pulmonary resection were assigned to the control group. Median follow-up was 27.3 months (range, 4.4 months to 90.9 months). Mean survivals for the treatment group and the control group were 64.9 and 18.1 months, respectively (P< .001). There was a statistically significant association between pulmonary resection and better survival (OR=78.408). One-year and 5-year local brain tumor control rates were 97.1% and 93.5%, respectively. CONCLUSIONS: The pulmonary resection and GKRS protocol could prolong survival in patients with thoracic stage I or II NSCLC, no extracranial metastases, and a limited number of small synchronous brain metastases.
