Advancing HER2-low breast cancer management: enhancing diagnosis and treatment strategies.

Background: Recent evidence brought by novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugates is leading to significant changes in HER2-negative breast cancer (BC) best practices. A new targetable category termed 'HER2-low' has been identified in tumors previously classified as 'HER2-negative'. Daily practice in pathology and medical oncology is expected to align to current recommendations, but patient access to novel anticancer drugs across geographies might be impeded due to local challenges.

Have we made progress in taking care of adolescents and young adults with cancer? Results of a European multi-professional survey.

Mutational profile of hereditary breast and ovarian cancer - Establishing genetic testing guidelines in a developing country.

Purpose: Because many countries lack the capacity to follow the international guidelines for genetic testing, we suggest the specific approach for establishing local genetic testing guidelines that could be applied in developing countries. We focus on hereditary breast (BC) and ovarian cancer (OC) in Serbia.

Methods: From the cohort of 550 persons who were referred for genetic counseling at the Institute for Oncology and Radiology of Serbia, 392 were selected.

From presentation to paper: Gender disparities in oncological research.

Gender disparities in scientific publications have been identified in oncological research. Oral research presentations at major conferences enhance visibility of presenters. The share of women presenting at such podia is unknown.

How to become a breast cancer specialist in 2018: The point of view of the second cohort of the Certificate of Competence in Breast Cancer (CCB2).

Breast cancer (BC) is the most frequent cancer in women and the leading cause of cancer death in females worldwide. Rapid research advancements add to the complexity of treatment options for this disease. It is known that the quality of patients' care is deeply affected by healthcare professionals following these advancements.

Treatment outcome in patients with breast conserving surgery after neoadjuvant therapy for breast carcinoma - a single institution experience.

Purpose: The aim of this study was to analyze outcomes of breast conserving surgery (BCS) after neoadjuvant treatment (NAT) in comparison to radical mastectomy (RM) after NAT in terms of disease-free survival (DFS), overall survival (OS) and patients' satisfaction with the esthetic outcomes of surgery.

Methods: This prospective study was conducted at the National Cancer Research Center of Serbia, Belgrade, from January 1st 2011 to December 31st 2015, on breast carcinoma patients receiving NAT. Treatment outcome was assessed by MDAPI (MD Anderson Prognostic Index).

Cardiac biomarkers for early detection and prediction of trastuzumab and/or lapatinib-induced cardiotoxicity in patients with HER2-positive early-stage breast cancer: a NeoALTTO sub-study (BIG 1-06).

Background: Biomarkers of cardiac damages, such as troponin T (TnT) and the amino-terminal fragment of brain natriuretic peptide (NT-proBNP), may be useful as early predictors of cardiac dysfunction. The role of these biomarkers in patients receiving lapatinib and/or trastuzumab before anthracyclines is unknown. This study explores TnT and NT-proBNP as predictors of early cardiac toxicity in neoadjuvant breast cancer patients.

The Prognostic Role of Androgen Receptor in Patients with Early-Stage Breast Cancer: A Meta-analysis of Clinical and Gene Expression Data.

Androgen receptor (AR) expression has been observed in about 70% of patients with breast cancer, but its prognostic role remains uncertain. To assess the prognostic role of AR expression in early-stage breast cancer, we performed a meta-analysis of studies that evaluated the impact of AR at the protein and gene expression level on disease-free survival (DFS) and/or overall survival (OS). Eligible studies were identified by systematic review of electronic databases using the MeSH-terms "breast neoplasm" and "androgen receptor" and were selected after a qualitative assessment based on the REMARK criteria.

A rare case of isolated adrenal metastasis of invasive ductal breast carcinoma.

Introduction: Isolated adrenal metastases of invasive ductal breast carcinoma are extremely rare. We report a case with isolated left adrenal metastases, verified three years after diagnosed breast carcinoma.

Case Outline: A 58-year-old female patient with a right breast tumor, clinically staged as IIIA (T2N2M0) started neoadjuvant anthracycline chemotherapy after biopsy which revealed invasive ductal breast carcinoma.

Luminal B breast cancer: molecular characterization, clinical management, and future perspectives.

Gene expression profiling has reshaped our understanding of breast cancer by defining and characterizing four main intrinsic molecular subtypes: human epidermal growth factor receptor 2-enriched, basal-like, luminal A, and luminal B subtypes. Luminal B breast cancer has been reported to have lower expression of hormone receptors, higher expression of proliferation markers, and higher histologic grade than luminal A. It also exhibits worse prognosis and has a distinct profile of response to hormone therapy and chemotherapy.

Prognostic, predictive abilities and concordance of BCL2 and TP53 protein expression in primary breast cancers and axillary lymph-nodes: a retrospective analysis of the Belgian three arm study evaluating anthracycline vs CMF adjuvant chemotherapy.

Given recent data on genetic heterogeneity within and individual's tumor, we investigated if there were differences in the prognostic and predictive abilities of BCL2 and TP53 protein expression in primary breast cancer (TU) and corresponding axillary lymph-nodes (LN). We used patient samples from the adjuvant Belgian three-arm study which randomized between anthracycline containing regimens and traditional CMF. The endpoints analyzed were overall survival (OS), event-free survival (EFS) and interactions between chemotherapy regimens.

Dual human epidermal growth factor receptor 2 blockade: another step forward in treating patients with human epidermal growth factor receptor 2-positive breast cancer.

Purpose Of Review: Many antihuman epidermal growth factor receptor (anti-HER2)-targeted agents, covering a broad spectrum of mechanisms of action, have been recently developed. The concept of dual anti-HER2 blockade has been preclinically and clinically assessed with positive results. In this article, the authors review the biologic rationale for dual HER2 blockade, along with the clinical findings.

New therapies in HER2-positive breast cancer: a major step towards a cure of the disease?

Overexpression of the human epidermal growth factor receptor 2 (HER2) predicts a poor prognosis in metastatic breast cancer. While the introduction of HER2-targeted therapies, such as the monoclonal antibody trastuzumab and the small-molecule tyrosine kinase inhibitor lapatinib, has significantly improved outcomes in HER2+ breast cancer compared with previously available therapies, use of these targeted therapies is often limited by the development of drug resistance and tolerability issues. These limitations create the need for further development and investigation of new targeted therapies that show potent and selective inhibition of these targets or closely connected molecular pathways.
