Objective To investigate the management of women with asymptomatic ovarian masses, to determine the appropriate duration of follow up, and to identify diagnostic indicators of growing cysts. Design Review of women's hospital records. Setting Tokyo Metropolitan Cancer Detection Center, Japan. Population Two hundred and twenty‐five pre‐ and postmenopausal women with a diagnosis of ovarian cyst ≥6 cm in diameter and normal serum level of CA125, diagnosed between 1 October 1990 and 25 December 1991. Main outcome measure Change in size of cyst as shown by ultrasound. Results Seventy‐five months after initial diagnosis, 29 (13%) of the masses had progressed, 31 (14%) had persisted, and 165 (73%) had regressed. One hundred and nine masses (48%) had regressed within six months of the initial diagnosis. In univariate analysis transvaginal ultrasonographic assessment of morphology findings, cyst diameter, carcinoembyronic antigen (CEA) and CA 19.9 were associated with the prognosis of the cyst. Multivariate regression analysis demonstrated that only the initial serum CA19‐9 level and serum CEA level were significant predictors of ovarian masses that regressed (P for trend = 0.004 and 0.02, respectively). Conclusion Simple ovarian cysts in patients with a normal level of CA125 have a low risk for ovarian cancer. Vaginal ultrasound at six months will identify regression of most simple cysts. CA19‐9 and CEA at the initial diagnosis are useful parameters to predict future regression of ovarian cysts.
