Summary

Radiological characteristics of breast microcalcifications, such as morphology and presence of a mass, can help predict malignancy. Specific types and combinations warrant open biopsy for definitive diagnosis, while others may consider stereotactic biopsy or follow-up.

Area of Science:

  • Radiology and Oncopathology
  • Breast Cancer Detection
  • Mammographic Analysis

Background:

  • Microcalcifications are crucial for early breast cancer detection.
  • The correlation between radiological and pathological features of microcalcifications requires further clarification.
  • Definitive biopsy indications for microcalcifications are not yet established.

Purpose of the Study:

  • To assess the relationship between full-field digital mammography classifications of breast microcalcifications and their pathological characteristics.
  • To identify mammographic features predictive of malignancy.

Main Methods:

  • Reviewed 103 mammographs with clustered microcalcifications from 98 patients who underwent open biopsy.
  • Analyzed pathological records alongside mammographic findings.

  • Performed univariate and multivariate analyses to evaluate the diagnostic value of radiological criteria.

    • Main Results:

    • Pathology revealed 65.05% malignant and 34.95% benign lesions.
    • Significant univariate predictors of malignancy included morphological type, presence of a mass, number of microcalcifications, and cluster distribution.
    • Multivariate analysis identified morphological type and presence of a mass as key significant predictors (P < 0.001).

    Conclusions:

    • Specific microcalcification types (e.g., types 4, 5, or type 3/2 with a mass) are highly indicative of cancer.
    • Open biopsy is recommended for definitive pathological diagnosis in suspicious cases.
    • Stereotactic biopsy or follow-up may be considered for less suspicious microcalcification morphologies.
