The recently published AJCC-TNM staging system for esophageal carcinoma made an obvious modification on N-classification based on the number of metastatic regional lymph nodes (LN). However, this classification might ignore the site at which these LNs occur, a factor that might be even more important in reflecting patients’ prognosis. A retrospective study(More)
OBJECTIVE To investigate the prognostic factors and influence of the number of lymph node metastases on survival and UICC-TNM classification in patients with thoracic esophageal cancer after curative resection. METHODS From 1985 to 1990, 1224 patients were surgically treated for thoracic esophageal cancer. The patients who died within 30 days after(More)
DNA methylation has been reported to become a potential powerful tool for cancer detection and diagnosis. However, the possibilities for the application of blood-based gene methylation as a biomarker for non-small cell lung cancer (NSCLC) detection and screening remain unclear. Hence, we performed this meta-analysis to evaluate the value of gene methylation(More)
OBJECTIVE To evaluate the impact of total number of removed regional lymph nodes (LN) during esophagectomy on TNM staging and long-term survival. METHODS Between 1984 and 1989, a total of 1098 patients with advanced squamous cell carcinoma of the thoracic esophagus were surgically treated, and the data were retrospectively analyzed. The survival was(More)
