Cancers, Vol. 12, Pages 819: Early Triple Negative Breast Cancer: Conventional Treatment and Emerging Therapeutic Landscapes Cancers doi: 10.3390/cancers12040819 Authors: Anna Diana Francesca Carlino Elisena Franzese Olga Oikonomidou Carmen Criscitiello Ferdinando De Vita Fortunato Ciardiello Michele Orditura Triple negative breast cancers (TNBCs) are characterized by worse prognosis, higher propensity to earlier metastases, and shorter survival after recurrence compared with other breast cancer subtypes. Anthracycline- and taxane-based chemotherapy is still the mainstay of treatment in early stages, although several escalation approaches have been evaluated to improve survival outcomes. The addition of platinum salts to standard neoadjuvant chemotherapy (NACT) remains controversial due to the lack of clear survival advantage, and the use of adjuvant capecitabine represents a valid treatment option in TNBC patients with residual disease after NACT. Recently, several clinical trials showed promising results through the use of poly ADP-ribose polymerase (PARP) inhibitors and by incorporating immunotherapy with chemotherapy, enriching treatment options beyond conventional cytotoxic agents. In this review, we provided an overview on the current standard of care and a comprehensive update of the recent advances in the management of early stage TNBC and focused on the latest emerging biomarkers and their clinical application to select the best therapeutic stra...

Endo Takabe We generated a 4-gene score with genes upregulated in LM2-4, a metastatic variant of MDA-MB-231 (DOK 4, HCCS, PGF, and SHCBP1) that was strongly associated with disease-free survival (DFS) in TCGA cohort (hazard ratio [HR]>1.2, p < 0.02). The 4-gene score correlated with overall survival of TCGA (HR = 1 .44, p < 0 .001), which was validated with DFS and disease-specific survival of METABRIC cohort. The 4-gene score was able to predict worse survival or clinically aggressive tumors, such as high Nottingham pathological grade and advanced cancer staging. High score was associated wit...

This articles reviews results of relevant breast cancer trials presented at the 2019 ESMO Meeting. In triple-negative disease, addition of pembrolizumab to standard neoadjuvant chemotherapy yielded a  pathologic complete response (pCR) rate of 64.8%, the highest pCR rate reported to date in this setting; in addition, a trend towards improved event-free survival was observed in the immunotherapy group. In pretreated patients with metastatic triple-negative breast cancer, single-agent pembrolizu mab was not superior to conventional chemotherapy. In metastatic hormone-receptor positive disease, an update of the MONA...

Authors: Hartkopf AD, Müller V, Wöckel A, Lux MP, Janni W, Ettl J, Belleville E, Schütz F, Fasching PA, Kolberg HC, Welslau M, Overkamp F, Taran FA, Brucker SY, Wallwiener M, Tesch H, Fehm TN, Schneeweiss A, Lüftner D Abstract In the near future, important translational questions of clinical relevance will be adressed by studies currently in progress. On the one hand, the role of PD-L1 expression must be further understood, after it was found to be relevant in the use of atezolizumab in first-line therapy of patients with metastatic triple-negative breast cancer (TNBC). No association between ef...

This study included 242 patients with primary triple-negative breast cancer (TNBC) who underwent resection without neoadjuvant chemotherapy between January 2004 and December 2014. The immunohistochemistry scoring for CD8 and T-bet expression on tumor-infiltrating lymphocytes (TILs) was defined as  ≥ 30 per 6.25 × 10−3 mm2.ResultsOf the 242 TNBC cases, CD8 was positively expressed in 127 (52.5%) tumors, and T-bet was positively expressed in 67 (27.7%) tumors. T-bet expression was significantly correlated with CD8 expression (p

CONCLUSIONS: The immune microenvironment of HR+/HER2-tumors differs according to tumor biology. This cohort of paired pre-/post-chemotherapy samples suggests a critical role for immunosuppressive macrophage expansion in residual disease. The role of macrophages in chemo-resistance should be explored and further evaluation of macrophage-targeting therapy is warranted. PMID: 31061067 [PubMed - as supplied by publisher]

In this study, we evaluated the therapeutic benefit of combining the TAB004 antibody with Liposomal-MSA-IL-2 in immune competent and human MUC1 transgenic (MUC1.Tg) mouse models of PDA and investigated the associated immune responses. Treatment with TAB004 + Lip-MSA-IL-2 resulted in significantly improved survival and slower tumor growth compared to controls in MUC1.Tg mice bearing an orthotopic PDA.MUC1 tumor. Similarly, in the spontaneous model of PDA that expresses human MUC1, the combination treatment stalled the progression of pancreatic intraepithelial pre-neoplastic (PanIN) lesion to adenocarcinoma. Treatment with t...
