Intra-operative assessment of axillary sentinel lymph nodes by frozen section-an observational study of 260 procedures.

Background: Sentinel lymph node biopsy (SLNB) has become the standard treatment for patients with invasive breast cancer. Intra-operative frozen section allows for the detection of nodal metastases, thereby allowing a simultaneous axillary lymph node dissection (ALND) for those patients with nodal metastases. We herein report the accuracy of frozen section in the detection of SLN metastases.

Isotope-guided surgery for nonpalpable breast cancer.

Background: The hook-wire technique is used to guide surgical excision of nonpalpable breast lesions. Recently, isotope has been used to guide the excision, and when sentinel node biopsy is performed during the same operation, the procedure is termed Sentinel Node and Occult Lesion Localization (SNOLL). We evaluated the use of this procedure for nonpalpable cancers in Chinese women.

Evaluation of MRI findings after polyacrylamide gel injection for breast augmentation.

Objective: Polyacrylamide gel injection mammoplasty has recently been used for breast augmentation. However, many complications have been reported including complications that in some patients resulted in the need for mastectomy. This article reviews the MRI appearances of various complications of polyacrylamide gel injection mammoplasty including breast asymmetry; intramammary or extramammary gel displacement, including intrathoracic extension; and glandular atrophy, inflammation, and infection resulting in mastectomy.
