We investigated the prognostic significance of subclassification of stage IIB lung cancer according to the eighth tumor-node-metastasis (TNM) classification. To this purpose, the prognostic outcomes of 226 stage IIB lung cancer patients who underwent surgery without adjuvant therapies between 2001 a...

Lung adenocarcinoma is the most common primary lung cancer seen in the United States. It falls under the umbrella of non-small cell lung cancer (NSCLC) and has a strong association with previous smoking. While incidence and mortality have declined, it remains the leading cause of cancer death in th...

Introduction: We investigated the validation of the seventh edition of the TNM staging (2009) system for lung cancer, retrospectively. Methods: From January 1990 to March 2004, 1629 patients who underwent lung resection with systemic lymph node dissection for non-small cell lung cancer at Nippon...

Introduction: The current study evaluated a large cohort of T2N0M0 NSCLC patients with different T2 descriptors to investigate the prognostic disparities and further externally validate the T category of these patients. Methods: The Kaplan-Meier Method with the log-rank test was used to plot sur...

Objectives: The eighth tumor-node-metastasis (TNM) classification system for lung cancer has been used since January 2017 and must be applied to an individual institution's database. Methods: We analyzed pathological stage data of 2756 patients who underwent resection of non-small-cell lung canc...
