ABSTRACT
PURPOSE:
The role of surgery for patients with non-small cell lung cancer (NSCLC) with clinical mediastinal lymph node metastasis (N2) remains controversial. We specified 4 criteria for performing initial surgery in these patients (single-station N2, non-bulky N2, N2 with regional mode of spread, and N2 without N1) and examined the outcomes to validate the treatment options.METHODS:
Between September 2002 and December 2010, of 1290 patients who underwent complete resection for NSCLC, 808 patients underwent initial standard resection, including 779 patients with cN0-1 and 29 with cN2. We compared the outcomes, and evaluated patients with cN2-pN2.RESULTS:
The median follow-up was 45.5 months (3-119 months). Seventy (9.0 %) and 24 (82.8 %) patients had p-N2 in the cN0-1 and cN2 groups, respectively (p < 0.0001). The 5-year disease-free survival (DFS) rates in the cN0-1 and cN2 groups were 73.3 and 50.6 %, respectively (p = 0.0053), and the 5-year overall survival (OS) rates were 81.3 and 71.1 %, respectively (p = 0.051). The 5-year DFS and OS of patients with cN2-pN2 were 52.5 and 72.6 %, respectively.CONCLUSIONS:
Patients with clinical N2 disease based on our criteria represent a highly specific group with a favorable prognosis. Resection should therefore be the initial treatment for these patients.Palavras-chave
