[Retrospective results of breast ultrasonographically-guided cytoponctions and microbiopsies within the breast cancer screening program of L'Ariana state in Tunisia]

To report the results of breast ultrasonographically-guided fine needle aspirations and needle biopsies within the breast cancer screening program of L'Ariana state in Tunisia. Our retrospective study include 143 patients, with mammographically detected lesions, which underwent a diagnostic percutanous ultrasonographically guided procedures. 57 patients underwent a fine needle aspiration, 25 underwent a needle biopsy and 61 patients underwent both procedures. Sensitivity and specificity of fine needle aspiration are of 84, 2% and 98, 5%. We report 13, 5% of non contributive results. The needle biopsy have a sensitivity of 97, 3% and a specificity of 100% with one false negative corresponding to an atypical ductal hyperplasia at the excisional biopsy. Fine needle aspiration is a reliable method of accurately establishing a diagnosis. Needle biopsy is recommended for a preoperative lesion characterisation before adequate treatment

[Surgical treatment of infraclinical breast lesions: preliminary results of the screening program of L'Ariana state]

To report clinical, radiological and histological characteristics of the infraclinical breast lesions patients recruited via the large scale mammography breast cancer screening of l'Ariana state in Tunisia. Retrospective study over a period of 2 years. The recruitment of patients made on the occasion of the program of breast cancer screening. During this period, 22 patients in our unity had a surgical excision after wire localization. Ten patients were recruited by means of systematic breast cancer screening. In these cases, the mammographic findings were classified B.I.R.A.D.S 4 in 7 cases and BIRADS type 5 in 3 cases. Definitive histology concluded to benign disease in 4 cases and malignancy 6 cases. This collaboration enables the diagnosis an invasive ductal carcinoma in three cases. The surgical excision after wire localization for non palpable breast lesions allows diagnosis of high-risk benign lesions and low-stage breast cancer. It is a reliable technique which indications have to be based on clinical and radiological strict criteria. This procedure is at present, and in developed countries, widely outstripped with the stereotactic core needle biopsy
