Symptoms

Studies on the accuracy of symptoms

Two case-control studies, both subject to results being inflated by spectrum bias,have been reported. The first found that women with ovarian cancer had symptoms of increased abdominal size, bloating, urinary urgency, and pelvic pain.[1] The smaller, second study found that women with ovarian cancer had pelvic/abdominal pain, increased abdominal size/bloating, and difficulty eating/feeling full.[2] The latter study created a symptom index that was considered positive if any of the 6 symptoms "occurred >12 times per month but were present for <1 year".They reported a sensitivity of 57% for early-stage disease and specificity 87% to 90%. In a large validation of the symptom index, the sensitivies were never over 70% whie the specificities were over 90%.[3]
