HER2-directed therapies are less effective in patients with ER(pos) compared to ER(neg) breast cancer, possibly reflecting bidirectional activation between HER2 and estrogen signaling pathways. We investigated dual blockade using anti-HER2 vaccination and anti-estrogen therapy in HER2(pos)/ER(pos) early breast cancer patients. In pre-clinical studies of HER2(pos) breast cancer cell lines, ER(pos) cells were partially resistant to CD4(+) Th1 cytokine-induced metabolic suppression compared with ER(neg) cells...

PURPOSE: Near-infrared diffuse optical spectroscopy (DOS) has been recently used to predict neoadjuvant chemotherapy response (NAC). In the present study, we explore the change in blood-oxygen content using DOS to predict NAC response against breast cancer. MATERIALS AND METHODS: A total of 20 patients were enrolled and underwent DOS scan with blood-oxygen detection before each treatment cycle. The first DOS scan was performed before NAC treatment (pretreatment), and subsequent scans were performed after each NAC treatment circle...

Background: The role of tumor-infiltrating lymphocytes (TILs) in breast cancer has been extensively studied over the last decade. High TILs levels have been associated with pathological response rate in the neoadjuvant setting and with better outcomes in the adjuvant setting. However, little attention has been paid to changes in TILs and residual TIL levels after neoadjuvant chemotherapy (NAC). We investigated TIL levels before, after chemotherapy, and their dynamics during treatment; and we assessed the correlation of these levels with response to NAC and prognosis...

BACKGROUND: Neoadjuvant-chemotherapy (NAC) is considered the standard treatment for locally advanced breast carcinomas. Accurate assessment of disease response is fundamental to increase the chances of successful breast-conserving surgery and to avoid local recurrence. The purpose of this study was to compare contrast-enhanced spectral mammography (CESM) and contrast-enhanced-MRI (MRI) in the evaluation of tumor response to NAC. METHODS: This prospective study was approved by the institutional review board and written informed consent was obtained...

Sentinel lymph node biopsy has replaced axillary lymph node dissection in those patients with clinically node-negative axilla without compromising their oncologic outcomes. Indication of neoadjuvant chemotherapy has been extended to patients to evaluate the pathologic response and to offer more conservative breast surgery. Sentinel lymph node dissection after neoadjuvant chemotherapy is feasible and accurate in patients with clinically node-negative patients. The timing of the sentinel lymph node biopsy, before or after medical treatment has been studied with benefits for each procedure...

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is the standard of care for locally advanced triple negative breast cancer, however, approximately 5% of cases show disease progression during NAC. Although downstaging is essential to create an opportunity for curative surgery and to improve the local control outcome in such a case, no additional line of chemotherapy has been established. CASE PRESENTATION: A 60-year-old woman was referred to our hospital for an axillary mass presenting three weeks ago and was diagnosed as having right locally advanced (T2N2M0, stage IIIA) triple negative breast cancer...

Traditional treatments for breast cancer fail to address therapy-resistant cancer stem-like cells that have been characterized by changes in epigenetic regulators such as the lysine demethylase KDM4. Here we describe an orally available, selective and potent KDM4 inhibitor (QC6352) with unique preclinical characteristics. To assess the anti-tumor properties of QC6352, we established a method to isolate and propagate breast cancer stem-like cells (BCSC) from individual triple-negative tumors resected from patients after neoadjuvant chemotherapy...

BACKGROUND: Tumor-infiltrating lymphocytes (TILs) are emerging as biomarkers mediating tumor response to treatments. Earlier studies have provided evidence that the level of TILs has prognostic value, particularly in triple-negative and human epidermal growth factor receptor-2-positive breast cancer. Moreover, the level of TILs has been associated with treatment outcome in patients undergoing neoadjuvant chemotherapy, and there is a strong correlation with pathologically complete response...

The role of the selective sentinel node biopsy (SNB) is increasing in relevance in breast cancer women with indication of neoadjuvant chemotherapy (NAC). The Radiosurgery Working Group of the SEMNIM is aware of the necessity of establishing the need for SNB before or after NAC, and also how to manage patients with axillary node-negative or node-positive. There is sufficient data to assess that the SNB with radioisotope techniques are feasible and safe in all these scenarios. An adequate axilla evaluation prior to surgery and the possibility of marking prior to NAC the nodes infiltrated must be the two main pillars to guarantee the success of the SNB...

Background: The most common cancer worldwide in women is breast cancer. The increasing number of cases each year, requires a novel curative approach that can combine oncological treatments and breast reconstruction yielding a pleasing and aesthetic breast that is a definitive and long lasting solution. Thus, the Immediate-DElayed AutoLogous (IDEAL) breast reconstruction principle was created to hold up to the standards of the needs of contemporary women. METHOD: The IDEAL protocol for breast reconstruction was developed in our department in cooperation with our breast surgery unit and describes a two-stage approach that implicates neoadjuvant radio-/ chemotherapy treatment regimes and tumor staging before the mastectomy in order to avoid post-mastectomy radiation...
