Update Breast Cancer 2019 Part 4 - Diagnostic and Therapeutic Challenges of New, Personalised Therapies for Patients with Early Breast Cancer. Geburtshilfe Frauenheilkd. 2019 Oct;79(10):1079-1089 Authors: Schütz F, Fasching PA, Welslau M, Hartkopf AD, Wöckel A, Lux MP, Janni W, Ettl J, Lüftner D, Belleville E, Kolberg HC, Overkamp F, Taran FA, Brucker SY, Wallwiener M, Tesch H, Fehm TN, Schneeweiss A, Müller V Abstract The further development of therapies for women with early breast cancer is progressing far more slowly than in the case of patients with advanced breast cancer and is additionally delayed compared to developments in metastatic breast cancer. Nonetheless, significant advancements have been able to be recorded recently. This review summarises the latest developments in view of the most recent publications and professional conferences. For hormone-receptor-positive patients, new aspects for the duration of antihormone therapy and with regard to the benefits of multigene tests have been published. In the case of HER2-positive patients, the value of post-neoadjuvant therapy and de-escalation of the therapy is discussed. In patients with triple-negative breast cancer, there is a question of whether the knowledge of the biological background of a homologous recombination deficiency (HRD) helps develop new therapies for this subtype. In particular the "use" of a BRCA1/2 mutation or the biological characteristic HRD as ...

AbstractPurpose of ReviewThis review will discuss recent important trials for the treatment of HER2-positive breast cancer, emphasize ongoing areas of development, and highlight areas of unmet need.Recent FindingsAdvances for early-stage treatment have been driven by key clinical trials with pertuzumab, neratinib, and TDM-1. In the adjuvant setting, dual HER2 targeting with trastuzumab and pertuzumab has demonstrated modest improvement in disease-free survival. Neratinib also showed modest benefit in the extended adjuvant setting after prior trastuzumab. Finally, for patients who did not achieve pathologic complete respons...

Authors: Takeshita T, Asaoka M, Katsuta E, Photiadis SJ, Narayanan S, Yan L, Takabe K Abstract Polo-like kinase 1 (PLK1), the most investigated member of the PLK family, plays a pivotal role both in the p53-mediated regulation of DNA damage repair and in mitosis, especially in the G2/M phase. However, the evidence on the clinical and prognostic relevance of PLK1 is limited to triple negative subtype among breast cancer (BC). We hypothesized that high expression of PLK1 is associated with TP53 inactivation, DNA repair deficiency, and worse prognosis in ER positive in BC in a large-scale cohort should clarify its cli...

Roche today announced that the European Medicines Agency ’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended the approval of Kadcyla® (trastuzumab emtansine) for the adjuvant (after surgery) treatment of adult patients with HER2-positive early breast cancer (eBC) who have residual invasive disease, in the breast and/or lymph nodes, after neoadjuvant (before surgery) taxane-based and HER2-targeted therapy.

The objective of this study is to determine factors related with axillary downstaging and complete pathological response (CPR), and how CPR influences the decision to perform bilateral mastectomy with immediate reduction. METHODS: A retrospective analysis of breast cancer patients who had undergone neoadjuvant chemotherapy and bilateral mastectomy with immediate reduction between 2000-2018 was performed. Two groups were compared:1) CPR and 2) non-CPR. Descriptive and comparative statistical analyses are provided. RESULTS: 69 patients; 26 (37.68%) reached CPR and 43 (62.32%) non-CPR. Median follow-up of 45.3 month...

AbstractBackgroundCharacterization of breast cancer phenotypes has improved our ability to predict breast cancer behavior. Triple-negative (TN) breast cancers have higher and earlier rates of distant events. It has been suggested that this behavior necessitates treating TNs faster than others, including use of neoadjuvant chemotherapy (NACT) if time to surgery is not rapid.MethodsA review of women diagnosed with non-inflammatory, invasive breast cancer was conducted using the National Cancer Database for patients not having NACT, diagnosed between 2010 and 2014. Changes in overall survival due to delay were measured by phe...

CONCLUSIONS: We have identified the TAF/FGF5/FGFR2/c-Src/HER2 axis as an escape pathway responsible for HER2 targeted therapies resistance in breast cancer which can be reversed by FGFR inhibitors. PMID: 31699826 [PubMed - as supplied by publisher]

CONCLUSION: Most mastectomies are advised for large tumour to breast size ratio, but there is an inconsistency in the use of NST to downsize tumours in patients with large ER+ or HER2+ cancers. The application of standardized recommendations for NST could reduce the number of mastectomies advised by MDTs. PMID: 31691270 [PubMed - as supplied by publisher]

Conclusions: With data obtained from patients treated in clinical practice, it has been possible to verify that the addition of pertuzumab to trastuzumab and neoadjuvant chemotherapy substantially increases the rate of pCR, especially in the HER2-enriched subtype but also in luminal subtypes, with no apparent benefit in basal-like tumors.

Authors: Neola B, Puppio B, Marino G, La Torre G Abstract BACKGROUND: Some Trials have demonstrated that the rate of false negative results of a sentinel lymph node biopsy in patients undergoing neoadjuvant chemotherapy is>10%. The aim of this study is to identify the predictive factors of a pathologic complete response in the axilla in order to make a better choice between the performance of an axillary lymphadenectomy or the performance of a sentinel lymph node biopsy. METHODS: All patients diagnosed with positive axillary lymph nodes and achieving a clinical complete response after a neoadjuvant therapy w...
