Objectives:

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 CA19-9 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.
