Assessment of tumor infltrating lymphocytes (TiLs) has been recognized as an additional tool for predicting survival in triple negative (TN) and HER2/neu positive (HER2+) subtypes breast cancer (BC). Recently, BC, including the above-mentioned characterized by low/undefined expression HER2/neu, isolated into a separate group, designated HER2-low BC. The relationship between clinical morphological parameters infiltration immunocompetent cells, associated macrophages (TAM), not studied to date. purpose study was identify significant relationships level subpopulations cells (Tils + TAM) Material Methods . examined surgical specimens 33 patients with Visual counting TILs assessment (IHC) T-helpers, T-killers, M1 M2 were carried out intratumor sites invasive edge primary tumor.

Despite the significant improvements made in breast cancer therapy during last decades, this disease still has increasing incidence and mortality rates. Different targets involved general processes, like cell proliferation survival, have become alternative therapeutic options for disease, with some of them already used clinic, CDK4/6 inhibitors luminal A tumors treatment. Nevertheless, there is a demand novel strategies focused not only on tumor cells, but also their microenvironment. Tumor microenvironment (TME) very complex dynamic system that, more than surrounding supporting actively participates development progression. During it clear that cellular acellular components TME differ between various subtypes shape differences regarding severity prognosis. The pivotal role controlling growth influencing responses to represents potential source strategies. In review, we present description multiple different subtypes, as well influence may exert response distinct therapies, which cases explain failure by occurrence relapses resistance. Furthermore, ongoing studies use developing treatments are described.

Abstract 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 tumors previously classified as ‘HER2-negative’. Daily practice pathology and medical oncology expected align current recommendations, but patient access anticancer drugs across geographies might be impeded due local challenges. Materials methods An expert meeting involving ten regional opinion leaders experienced BC management four Central Eastern Europe (CEE) countries (Bulgaria, Croatia, Serbia, Slovenia) was held. Herein we summarized the situation of HER2-low metastatic (mBC), challenges, action plans prevent delays testing treatment based on opinion. Results Gaps differences at multiple levels were countries. These included variability epidemiology data, certification laboratories quality control, reimbursement conditions for mBC. While clinical decisions aligned international guidelines use, optimal innovative restricted or limitative conditions. Conclusions Preventing mBC diagnosis treatments crucial optimize outcomes. Multidisciplinary joint efforts pro-active discussions between clinicians decision makers are needed improve care patients CEE

Abstract: Breast cancer (BC) currently represents one of the most prevalent cancers among women worldwide and leading cause death women, also negatively affecting quality life (QoL) in patients. Over past two decades, BC research has led to extraordinary advances our understanding disease, resulting more effective treatments. However, its occurrence is still increasing. Several new treatments are now under development worldwide, but they not devoid wellknown side effects, a great number patients develop endocrine resistance. Nevertheless, design synthesis suitable strategies drugs treat breast cancers, overcome resistance obtain better therapeutic outcomes needed. In this review, we summarize therapies clinical studies ongoing Italy for treatment BCs, mainly HER2+ MBC, HER2-low TNBC, focusing on recent ones, consideration diverse facets, including some aspects related QoL. Finally, usefulness physical activity will be cited.
