title: CA-125 levels in ruptured and unruptured tubal ectopic pregnancies.
abstract: OBJECTIVE
  This prospective, single-blind and controlled clinical study aimed to research if CA-125 levels could be a useful test in the differential diagnosis of intact and ruptured tubal ectopic pregnancy.
  
  
  METHODS
  Sixty-five women with tubal ectopic pregnancy of 5-10 weeks' duration (27 women with ruptured tubal ectopic pregnancy [REP] and 38 women with unruptured tubal ectopic pregnancy [UREP]) and 65 women with normal intrauterine pregnancy (NIUP) of the same gestational age were studied prospectively. Serum CA-125 levels were measured in all women and these levels were compared among the REP, UREP, and NIUP groups.
  
  
  RESULTS
  The mean CA-125 levels didn't show any significant difference between the REP and NIUP groups (P > 0.05). The mean CA-125 levels of these two groups were higher than that in the UREP group (P < 0.01, P < 0.001, respectively). The dispersion ratios of the CA-125 levels had a statistically significant difference between the REP and UREP groups (chi(2): 42.44, P < 0.0001). CA-125 levels weren't correlated with gestational weeks in the REP and UREP groups (r: 0.005, P > 0.05; r: 0.008, P > 0.05, respectively).
  
  
  CONCLUSIONS
  In intact tubal ectopic pregnancies, expectant or managed with medical treatment, the increase of CA-125 levels in the serial measurements could be a supplementary test for an early diagnosis of tubal rupture.
