Summary

Rising CA-125 levels can detect relapsed ovarian cancer about six months before symptoms develop. Therefore, many asymptomatic patients have routine CA-125 measurements during follow-up. The only trial of CA-125 surveillance after first-line therapy randomized patients to early or delayed treatment after a doubling of CA-125 level. It showed those in the early arm had no survival benefit and worse quality of life. The trial was criticized as few patients had secondary surgery, yet randomized trials show conflicting results on the value surgery. Patients should be aware that recurrent ovarian cancer is not curable and require information on surveillance options.
