Abstract
Objective: To determine the relationship among tumor malignancy, invasion, and plasma D-dimer(DD) levels via a retrospective analysis of the correlation between preoperative plasma DD levels and postoperative pathology parameters in esophageal cancer patients. Methods: A total of 101 esophageal cancer patients without coagulation among preoperative plasma DD levels and postoperative pathology parameters in esophageal cancer patients who underwent radical operation between January 2009 to April 2010 were enrolled. The preoperative plasma DD levels, postoperative pathology T, N Grade, number of metastatic lymph nodes, tumor position, tumor length, and TNM stage were recorded. A statistic analysis of the above parameters was performed to reveal the correlation between plasma DD levels and tumor pathology features. Results: Preoperative plasma DD level has no correlation with Grade and tumor length, but shows positive correlation with pathology T, N status, and TNM stage, and has strong positive correlation with numbers of metastatic nodes. In addition, lower-third thoracic esophageal cancer patients have higher DD level than middle-third thoracic cases. Conclusion: Plasma DD level has a positive correlation with T stage, N stage, TNM stage, and number of positive lymph nodes. It also has important clinical significance.
