P1.12-17 Overall Survival and Recurrence After Surgical Resection of Pure and Mixed Large Cell Neuroendocrine Tumors

Abstract

serum level of SCC (p<0.001), pR0 resection (p¼0.02), adjuvant chemotherapy (p<0.001), and histological pure SCLC (p¼0.002). In preoperative factor, multivariate Cox proportional hazard model analysis revealed that overall survival was shorter in patients with increased SCC levels and cN1or 2. Conclusion: We conclude that pulmonary resection for early-stage SCLC is a safe and effective treatment strategy, and adjuvant chemotherapy may be useful in patients undergoing surgery in a practical management. Increased SCC levels and cN1 or 2 were identified as prognosis-related criteria for a poor prognosis of resected early SCLC.
