From the Guidelines

Ovarian cysts are managed based on size, among other factors, with a focus on minimizing morbidity, mortality, and optimizing quality of life. The management of ovarian cysts prioritizes the patient's overall well-being, taking into account the cyst's size, characteristics, and the patient's symptoms, age, and menopausal status. According to the most recent and highest quality study by 1, simple cysts, regardless of size and menopausal status, are not associated with an increased risk of cancer. Key factors in managing ovarian cysts include:

  • Cyst size: Simple, asymptomatic ovarian cysts smaller than 5 cm in premenopausal women and smaller than 1 cm in postmenopausal women can be observed with follow-up ultrasound in 8-12 weeks to ensure resolution 1.
  • Cyst characteristics: Simple vs. complex cysts, as well as the presence of symptoms, influence management decisions 1.
  • Patient age and menopausal status: Premenopausal women with simple cysts < 5 cm do not require follow-up, while postmenopausal women with simple cysts > 3 cm may require annual follow-up for up to 5 years 1.
  • Symptomatic cysts: Pain management with analgesics like NSAIDs or hormonal contraceptives may be necessary to prevent new cyst formation 1. The size-based approach to managing ovarian cysts aims to balance the risks of complications, such as torsion, rupture, or malignancy, with the benefits of minimizing interventions and optimizing quality of life. In general, cysts larger than 10 cm often warrant surgical evaluation due to increased risk of complications, while smaller cysts may be safely monitored with repeat imaging 1. Ultimately, the management of ovarian cysts should be individualized, taking into account the patient's unique characteristics, symptoms, and preferences, with the goal of minimizing morbidity, mortality, and optimizing quality of life.

From the Research

Ovarian Cyst Management

  • Ovarian cysts are managed based on several factors, including size, symptoms, and patient's reproductive goals 2, 3, 4, 5, 6.
  • The size of the cyst is an important factor in determining the management approach, with larger cysts being more likely to require surgical intervention 3, 6.
  • Simple ovarian cysts, even in postmenopausal women, can be safely followed without intervention if they are small and have a benign appearance on ultrasound 4.
  • The American College of Obstetricians and Gynecologists (ACOG) recommends conservative management for simple cysts found on ultrasound, with follow-up examinations to monitor for any changes 4.
  • Expectant management, or watchful waiting, is a viable approach for functional ovarian cysts, with studies showing that most cysts resolve on their own within a few cycles 2, 5.

Factors Influencing Management

  • Cyst characteristics, such as size, pathology, and bilaterality, can influence the management approach, with larger cysts and those with suspicious features requiring more aggressive management 3, 6.
  • Patient's age and reproductive goals also play a role in determining the management approach, with younger women and those desiring fertility being more likely to undergo conservative management 3, 5.
  • Ultrasound appearance and cancer antigen 125 levels can help distinguish between benign and malignant ovarian cysts, guiding the management approach 4, 6.
