Changes in Biomarker Status in Metastatic Breast Cancer and Their Prognostic Value.
Conclusion: Changes in biomarker status are not rare, and usually occur in an unfavorable direction in breast cancer metastases. Negative conversion of ER status is a predictor of poor prognosis. Thus, it is beneficial to evaluate changes in biomarker status in MBC not only for the purpose of determining treatment options but also for prognostication of patients. PMID: 31598343 [PubMed]
ConclusionsSmall sub-sets of breast cancers with high TMB exist and may present an opportunity for effective immunotherapeutic targeting.
Conclusion: The bioactivity prediction shows that all compounds are active to moderately active. These positive results show that it could be further investigated and explored.
Abstract Introduction: Clinicopathologic and prognostic significance of body mass index (BMI) in breast cancer (BC) patients remained conflicting. We aimed to investigate and modify the impact of BMI on clinicopathological significance and survival in western Chinese BC patients. Materials and Methods: 8,394 female BC patients from Western China Clinical Cooperation Group (WCCCG) between 2005 and 2015 were identified. Multivariable logistic regression and Cox proportion hazard regressions were used to examine the difference of clinicopathologic and survival characteristics between BMI categories. Results...
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.
A new study confirms that a CDK4/6 blocker plus endocrine therapy is better than chemotherapy in young women with HR+, HER2- metastatic disease.Medscape Medical News
(European School of Oncology) Patients with HER2-positive breast cancer, whose disease has progressed after being treated initially with pertuzumab in combination with trastuzumab and a taxane, can respond well to treatment with T-DM1 -- a drug that combines trastuzumab with an anti-cancer drug called DM1. The research is presented at the Advanced Breast Cancer Fifth International Consensus Conference (ABC5) and published simultaneously in published in Clinical Breast Cancer journal.
Conclusions: Use of the 21-gene rs assay could be a cost-effective strategy for Ontario patients with estrogen receptor-positive, her2-negative early bca and 1-3 positive lns. PMID: 31708649 [PubMed - in process]
In a new study, patients with HR+/HER2- early stage breast cancer completed 2 years of adjuvant palbociclib with a similar toxicity profile as that observed in the metastatic setting.Annals of Oncology
AbstractPurpose of ReviewTo summarize and discuss the available evidence and ongoing efforts in order to establish the efficacy and safety of immunotherapeutic approaches in HER2-positive breast cancer.Recent FindingsThe introduction into the clinic of anti-HER2 –targeted therapies more than 15 years ago resulted in a substantial improvement in the outcome of patients with HER2-overexpressing breast cancer. However, only patients with the highest levels of HER2 expression will potentially benefit from these therapies and, unfortunately, many patients prog ress or relapse after optimal treatment. As metastatic breast ...
AbstractBackground.Immune checkpoint inhibitors are active in a broad range of cancers, including programmed death ligand 1 (PD‐L1)‐positive, triple‐negative, metastatic breast cancer (MBC). Antibody‐dependent cell‐mediated cytotoxicity is a mechanism of action of trastuzumab. We performed a phase Ib trial of durvalumab and trastuzumab in HER2‐positive MBC previously treated with chemotherapy and anti‐HER2 antibodies to assess safety, efficacy, and correlative endpoints.Patients and Methods.Patients with HER2‐positive MBC were enrolled on a standard 3 + 3 design. Dose level 1 was durvalumab (1,125 mg intrav...
