The impact of tumor size on the association of the extent of lymph node resection and survival in clinical stage I non-small cell lung cancer

摘要

Introduction: Lymph node evaluation for node-negative non-small cell lung cancer (NSCLC) is associated with long-term survival but it is not clear if smaller tumors require as extensive a pathologic nodal assessment as larger tumors. This study evaluated the relationship of tumor size and optimal extent of lymph node resection using the National Cancer Data Base (NCDB).
