Correlation of Preoperative Serum and Intraoperative Peritoneal Lavage Fluid Ca-125 Levels with Postoperative Tumor Histology in Patients with Endometrial Cancer: A Prospective-Controlled Study
Abstract
Background The role of Ca-125 in endometrial cancer is not fully known. Some authors have reported high Ca-125 levels in patients with recurrent or advanced endometrial cancer, whereas others have stated that Ca-125 levels and the advance of the disease were not correlated in endometrial cancer. This makes it inevitable for clinicians to search for different measurement methods or interpretation of the present tumor markers. The aim of this study was to evaluate the relationship between Ca-125 values of the serum and abdominal lavage fluid and postoperative histopathological parameters in patients with endometrial carcinoma. Methods The study included patients who were diagnosed with endometrial cancer in the Gynecology Clinic and were planned to undergo surgery. The correlations of clinicopathological parameters with preoperative values of Ca-125 measured from serum and abdominal lavage fluid were investigated. The Spearman correlation test was applied in the analysis of correlations of serum and abdominal lavage fluid Ca-125 values with postoperative tumor characteristics. Results The serum Ca-125 values were determined to be positively correlated with surgical stage, tumor diameter, and lymph node involvement (p = 0.03; p = 0.04; and p = 0.01, respectively). No correlation was determined between tumor grade and serum Ca-125 level. The level of Ca-125 in the abdominal lavage fluid was observed to be correlated with surgical stage and tumor grade, but not with tumor diameter or lymph node involvement (p = 0.01, p = 0.04, respectively). Conclusions The value of Ca-125 in the abdominal lavage fluid has a positive correlation with the surgical stage and tumor grade in patients with endometrial carcinoma.
