The ARTemis Trial tested standard neoadjuvant chemotherapy±bevacizumab in the treatment of HER2-negative early breast cancer. We compare data from central pathology review with report review and also the reporting behavior of the two central pathologists. Eight hundred women with HER2-negative early invasive breast cancer were recruited. Response to chemotherapy was assessed from local pathology reports for pathological complete response in breast and axillary lymph nodes. Sections from the original core biopsy and surgical excision were centrally reviewed by one of two trial pathologists blinded to the local pathology reports...

According to the St. Gallen 2011 consensus, proper qualification of breast cancer patients for treatment requires taking into consideration the division into biological types of neoplasms. The goal of this work was to assess the prevalence of all biological types of breast cancer in the population of Kuyavian-Pomeranian province. We determined the influence of particular types of neoplasms on the degree of disease progression and the choice of therapeutic management. The study was conducted on a group of 2653 patients treated surgically due to malignant breast tumors in the Oncology Centre in Bydgoszcz...

The axillary reverse mapping (ARM) technique has been described as an attempt to map and preserve the upper extremity lymphatic drainage during axillary lymph node dissection (ALND) and/or SLNB. This technique is based on the hypothesis that the lymphatic pathway from the upper extremity is not involved by metastasis from primary breast cancer. The ARM node/s however, has been found, in various studies, to be involved with metastatic foci in patients with extensive axillary lymph node metastases. Therefore, the oncological safety of this procedure has not yet been determined...

INTRODUCTION: Ultrasound (US) is conventionally performed to determine effects of neoadjuvant chemotherapy (NAC) on breast cancer. In patients with triple-negative breast cancer (TNBC), higher pathological complete response (pCR) predicts the most favorable survival outcome. We aimed to predict pCR to NAC using echogenicity changes in US region of interest (ROI) in patients with TNBC. METHODS AND MATERIALS: We retrospectively determined clinicopathological characteristics of 52 patients with primary TNBC who underwent NAC...

RATIONALE AND OBJECTIVES: We present an optical mammography study that aims to develop quantitative measures of pathologic response to neoadjuvant chemotherapy (NAC) in patients with breast cancer. Such quantitative measures are based on the concentrations of oxyhemoglobin ([HbO2]), deoxyhemoglobin ([Hb]), total hemoglobin ([HbT]), and hemoglobin saturation (SO2) in breast tissue at the tumor location and at sequential time points during chemotherapy. MATERIALS AND METHODS: Continuous-wave, spectrally resolved optical mammography was performed in transmission and parallel-plate geometry on 10 patients before treatment initiation and at each NAC administration (mean number of optical mammography sessions: 12, range: 7-18)...

BACKGROUND: A relationship between baseline tumor-infiltrating lymphocytes (TIL) and outcomes has been described in HER2-positive breast cancer. Nevertheless, the magnitude of this association and whether this effect differs based on the type of anti-HER2 agent remain controversial. This meta-analysis investigated the association between baseline TIL and pathologic complete response (pCR) rates in HER2-positive breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab and lapatinib either alone or in combination...

REVIEW
Lisa A Newman
Treatment of early-stage invasive breast cancer with breast-conserving surgery plus radiation therapy (RT) yields overall survival outcomes equivalent to those achieved with mastectomy. Further, breast-conserving surgery is endorsed by the National Comprehensive Cancer Network as being supported by the highest-level, category 1 evidence. Advances in pathologic evaluation, management of multiple tumors, oncoplastic lumpectomy techniques, neoadjuvant chemotherapy, and hypofractionated RT can expand the pool of patients eligible for breast-conserving surgery...

BACKGROUND: Circulating tumor cells (CTCs) are linked to metastatic relapse and are regarded as a prognostic marker for human cancer. High expression of plakoglobin, a cell adhesion protein, within the primary tumor is positively associated with CTC clusters in breast cancer. In this study, we investigated the correlation between plakoglobin expression and survival of breast cancer. METHODS: We evaluated 121 breast cancer patients treated with neoadjuvant chemotherapy...
