Processing and Reporting of Breast Specimens in the Neoadjuvant Setting.

Processing and Reporting of Breast Specimens in the Neoadjuvant Setting. Surg Pathol Clin. 2018 Mar;11(1):213-230 Authors: Bossuyt V Abstract Standardization of quantification of residual disease in the breast and lymph nodes with routine pathologic macroscopic and microscopic evaluation leads to accurate and reproducible measures of response to neoadjuvant treatment. Multidisciplinary collaboration and correlation of clinical, imaging, gross and microscopic findings is essential. The processing approach to post-neoadjuvant breast cancer surgical specimens and the elements needed in the pathology report are the same regardless of breast cancer subtype or type of neoadjuvant treatment. The residual cancer burden incorporates response in the breast and in the lymph nodes into a score that can be combined with other emerging prognostic factors. PMID: 29413658 [PubMed - in process]

This study identified chemotherapeutic agents that up-regulate programmed cell death ligand-1 (PD-L1) and galectin-9 (Gal-9) in breast cancer cells. Immunohistochemical (IHC) staining was used to evaluate changes in PD-L1 and Gal-9 expression in the tumor tissue of triple-negative breast cancer (TNBC) patients who received anthracycline- and taxane-based neoadjuvant chemotherapy. To determine whether PD-L1 and Gal-9 expression changes were attributable directly to chemotherapeutics, MDA-MB-231 cells and HS578 T cells were treated with different concentrations of anthracycline and taxane. Expression levels of PD-L1 a...

SummaryThe 40th  International San Antonio Breast Cancer Symposium offered a multifaceted platform for the presentation of several innovative therapeutic approaches. The results of these preclinical and clinical studies provided insight into the development of novel therapy concepts from the laboratory bench to t he bedside of breast cancer patients. One main focus of last year’s symposium was the search for synergisms and opportunities for collaboration between basic research scientists and investigators in drug development. Highlights of these topics included preclinical data on selective estrogen recept ...

Abstract PURPOSE:  To evaluate the time-intensity curve (TIC) parameters on contrast-enhanced ultrasound (CEUS) for early prediction of the response of breast cancer to neoadjuvant chemotherapy (NAC). MATERIALS AND METHODS:  This prospective study included 41 patients with breast cancer. CEUS was performed before and after the first cycle of NAC. TIC parameters were analyzed for different regions of interest (ROIs). ROI 1 targeted the hotspot area of greatest enhancement, ROI 2 delineated the area of hyperenhancement, ROI 3 included the entire tumor on grayscale ultrasound, and ROI 4 encircled the n...

Conclusions: Our study showed that APOBEC3B mRNA expression correlated with sensitivity to NAC in breast cancer patients. In contrast to previous studies, APOBEC3B mRNA expression was not associated with breast cancer prognosis in patients receiving NAC. PMID: 30093965 [PubMed]

This patient presents with stage IV, cT4dN3cM1 oligometastatic inflammatory breast cancer (IBC) (1). The initial treatment would be neoadjuvant chemotherapy (NAC). In the absence of progression with NAC, we would recommend mastectomy with axillary lymph node dissection and postmastectomy radiation therapy (PMRT). Given IBC's penchant for locoregional recurrence and progression to carcinoma en cuirasse, an aggressive approach to PMRT is warranted, despite the presence of initial limited metastatic disease.
