Background: In recent years, preoperative volume reduction of locally advanced breast cancers, resulting in higher rates of breast-conserving surgery (BCS), has become increasingly important also in postmenopausal women. Clinical interest has come to center on the third-generation nonsteroidal aromatase inhibitors (AIs), including letrozole, for such neoadjuvant endocrine treatment. This usually lasts 3-4 months and has been extended to up to 12 months, but optimal treatment duration has not been fully established.

The VB is a safe method for extracting breast tissue for histological workup. The technique allows the resection of breast tissue up to 8 cm3. Besides the diagnostic indications, the method qualifies for a therapeutic resection of symptomatic benign lesions (e. g. fibroadenomas). The technique should be used in specialized breast centers working in a multidisciplinary setup. This paper is an expert's recommendation for the use of VB under sonographic guidance. It is not formulated as a nationwide guideline.

K E Y W O R D S:

A good separation exists between benign and malignant lesions in elasticity, corresponding with specific signal intensity and morphologic data. Further clinical studies with a larger number of patients are needed for extended validation.

Background: Minimal invasive breast biopsy is standard care for the diagnosis of suspicious breast lesions. There are different vacuum biopsy (VB) systems in use. The aim of the study was to determine the differences between the 8-gauge and the 11-gauge needle with respect to a) diagnostic reliability, b) complication rate and c) subjective perception of pain when used for vacuum-assisted breast biopsy.

Cystosarcoma phyllodes (CP), otherwise known as phyllodes tumour (PT) of the breast, is a very rare but locally aggressive fibroepithelial tumour in its malignant form, and accounts for 0.3-1% of all breast neoplasias. Using 4 cases reports with different histological classifications as examples (benign-borderline-malignant), we describe the (differential) diagnosis and treatment options of this tumour entity and give an additional review of the available literature.

Exact MRI-guided preoperative localization of exclusively MRI-detected breast lesions by using a modified embolization coil is feasible with excellent precision. Advantages over wire localization procedures are the possibility of specimen x-ray and the independence from time and place of operation.
