Summary

Management of complex breast cysts can often involve follow-up imaging instead of immediate intervention. This study found a low malignancy rate of 0.3% in complex cysts, supporting conservative management strategies.

Area of Science:

  • Radiology
  • Breast Imaging
  • Oncology

Background:

  • Complex cysts are frequently encountered in breast imaging.
  • Current management strategies vary, with a need to define the optimal approach.
  • Evaluating the malignancy rate is crucial for guiding clinical decisions.

Purpose of the Study:

  • To assess current management strategies for complex breast cysts.
  • To determine the necessity of intervention for these lesions.
  • To evaluate the malignancy rate associated with complex cysts.

Main Methods:

  • A retrospective review of 4562 breast sonograms over 18 months identified 308 complex cysts in 252 women.
  • Data collected included patient demographics, risk factors, aspiration/biopsy results, and follow-up imaging.
  • Management recommendations were analyzed.

Main Results:

  • Management included 6-month or 1-year follow-up (161 patients), aspiration (82), aspiration with core biopsy (62), and excisional biopsy (3).
  • No malignancies were found in patients managed with follow-up imaging or aspiration alone.
  • One malignancy (ductal carcinoma in situ) was diagnosed in a patient who underwent core biopsy.

Conclusions:

  • The overall malignancy rate for complex cysts was 0.3% (1/308).
  • This rate is lower than that for mammographically probably benign lesions (BI-RADS category 3).
  • The low malignancy yield suggests that follow-up imaging is a suitable management strategy for complex cysts, potentially reducing the need for invasive procedures.
