Ovarian Cysts: Follow-up
Updated: Mar 19, 2008
Follow-up
Deterrence/Prevention
- Current use of oral contraceptive pills protects against the development of functional ovarian cysts. Current and previous use within 15 years reduces the risk of epithelial ovarian cystadenocarcinoma.
- All women should undergo an annual gynecologic examination. No generalized screening test is available for ovarian cystadenocarcinoma, but women at high risk based on family history or previous history of breast cancer should undergo an annual ultrasonographic examination and CA125 test. Referral for genetic counseling should be considered.
- Women at high risk for ovarian cystadenocarcinoma may be offered prophylactic oophorectomy, which will prevent the development of ovarian cancer but not peritoneal carcinoma.
Complications
- Torsion
- Rupture
- Hemorrhage
- Malignant change: The potential of benign ovarian cystadenomas to become malignant has been postulated but, to date, remains unproven. Malignant change can occur in a small percentage of dermoid cysts and endometriomas.
Prognosis
- The prognosis for benign cysts is excellent. All such cysts may occur in residual ovarian tissue or in the contralateral ovary.
- Mortality associated with malignant ovarian carcinoma is related to the stage at the time of diagnosis, and patients with this carcinoma tend to present late in the course of the disease. The 5-year survival rate overall is 41.6%, varying between 86.9% for FIGO stage Ia and 11.1% for stage IV.
- Granulosa cell tumors are associated with an 82% survival rate, whereas squamous cell carcinomas arising in a dermoid cyst are associated with a very poor outcome.
- Most germ cell tumors are diagnosed at an early stage and are associated with an excellent outcome. Advanced-stage dysgerminoma are associated with a better outcome compared to nondysgerminomatous germ cell tumors.
- A distinct group of less aggressive tumors of low malignant potential runs a more benign course but still is associated with definite mortality. The overall survival rate is 86.2% at 5 years.

Miscellaneous
Medicolegal Pitfalls
- Any pelvic mass should be assumed to be a cancer until proven otherwise, particularly in a patient with a prior history of breast cancer or a family history of breast/ovarian cancer.
- An ultrasonographic examination of the pelvis should always be obtained if a patient is thought to have a pelvic mass on clinical examination.
- If a patient has large fibroids, missing concomitant ovarian pathology, both clinically and on ultrasonographic examination, is possible.
- Always be vigilant about patients with an increased risk of ovarian cancer, and arrange appropriate counseling.
Special Concerns
- Ovarian cysts in pregnancy
- Because of the routine use of ultrasonography, ovarian cysts are commonly diagnosed in pregnancy. Cysts should be evaluated in pregnant patients the same way as in nonpregnant patients, with ultrasonographic examinations and CA125 testing. MRI is preferable to CT scanning, but both modalities should be avoided in the first trimester.
- In addition to the normal complications of cysts, they may cause obstructed labor in pregnancy.
- Benign simple cysts can be monitored, and most resolve spontaneously.
- Persistent cysts larger than 5-10 cm or those that are symptomatic or have features suggestive of malignancy may be removed surgically, preferably in the second trimester.
- Ovarian cysts occurring in children
- In a child found to have a symptomatic abdominopelvic mass, the ovary is the most common site of origin.
- Although such masses are infrequent occurrences, the percentage due to malignant tumors is thought to be higher than for older age groups. The most common are germ cell tumors, followed by epithelial and granulosa cell tumors. Such tumors may be partially cystic.
