title: Elevations of serum CA-125 predict severity of acute appendicitis in males.
abstract: BACKGROUND
  Acute appendicitis (AA) is a common indication for urgent abdominal surgery. CA-125 glycoprotein antigen is a non-specific marker for epithelial ovarian cancer; CA-125 serum levels also increased in the conditions of peritoneal inflammation. The aim of this study was to examine the correlation between serum CA-125 levels and AA.
  
  
  METHODS
  All emergency department (ED) patients with suspected AA were prospectively enrolled in the study. The serum level of CA-125 was checked in every patient on arrival to the ED in addition to the routine clinical and laboratory evaluation. Data regarding demographic, clinical, radiological, operative and pathological features were analysed.
  
  
  RESULTS
  One hundred consecutive patients (48 males) were enrolled in the study. We found a statistically significant correlation between CA-125 levels in males and the severity of appendicitis as described in the operative and pathology reports (P = 0.008 and P = 0.02, respectively). In addition, we observed a trend towards higher levels of CA-125 in males with AA compared with males without AA (9.9 ± 4.7 versus 7.8 ± 3.2 U/mL, respectively; P = 0.09).
  
  
  CONCLUSIONS
  CA-125 levels correlate with the severity of appendicitis in males and may serve as a surrogate marker for the severity of other intra-abdominal surgical diseases.
