  • Title: [Radiosurgical labeling of non-palpable mammary lesions].
    Author: Aguirre B, Gutiérrez L, Ortega D, Laupheimer S, Taborga M.
    Journal: Rev Med Chil; 1997 Sep; 125(9):1032-5. PubMed ID: 9595794.
    Abstract:
    BACKGROUND: The frequency of breast cancer is increasing worldwide and mammography allows the diagnosis of concealed lesions. AIM: To assess the diagnostic yield for carcinoma of non palpable lesions detected by mammography. PATIENTS AND METHODS: We studied 46 patients, aged 24 to 67 years old, in whom a radiosurgical labeling of non palpable mammary lesions was performed. In all patients, a surgical biopsy was obtained, but the pathological study was available in only 40 patients. RESULTS: The mammographic appearance of lesions were microcalcifications in 40% of women, stellate images in 27.5%, asymmetry in density in 5% and the association of microcalcifications and other signs in 20%. Seventy seven percent of lesions were benign. Four patients had an in situ ductal carcinoma, two had a predominantly in situ carcinoma and 4 had an invasive ductal carcinoma. CONCLUSIONS: Our results are similar to those reported abroad. The finding of 5 minimal carcinomas underscores the effectiveness of mammography as a screening method for breast cancer.
