Relapse levels of CA-125 in patients who developed image-identified relapse of serous ovarian, tubal, and peritoneal cancers (median, 64.0 U/ml; IQR, 29.4 U/ml to 134.1 U/ml) were significantly higher than the highest CA-125 level recorded during follow-up in patients who did not develop relapsed disease (median, 12.8 U/ml; IQR, 9.8 U/ml to 18.8 U/ml; P < 0.001).
