Is the CTS5 a helpful decision-making tool in the extended adjuvant therapy setting?

Purpose: The Clinical Treatment Score post-5 years (CTS5) is an easy-to-use tool estimating the late distant recurrence (LDR) risk in patients with hormone receptor-positive breast cancer after 5 years of endocrine therapy (ET). Apart from evaluating the prognostic value and calibration accuracy of CTS5, the aim of this study is to clarify if this score is able to identify patients at higher risk for LDR who will benefit from extended ET.

Methods: Prognostic power, calibration, and predictive value of the CTS5 was tested in patients of the prospective ABCSG-06 and -06a trials (n = 1254 and 860 patients, respectively).

Current Standards and Future Outlooks in Metastatic Her2-Positive Breast Cancer.

Background: Approximately 20% of all breast cancer cases show overexpression or amplification of the human epidermal growth factor receptor 2 (Her2) [Cancer Epidemiol Biomarkers Prev. 2017;26(4):632-41]. With the introduction of trastuzumab, lapatinib, and pertuzumab to the realm of treatment, a new era of antibody-drug conjugates had only begun.

Tumor Microenvironment in Male Breast Carcinoma with Emphasis on Tumor Infiltrating Lymphocytes and PD-L1 Expression.

Male breast cancer (MBC) is rare and usually presents as a locally advanced disease. Stromal tumor-infiltrating lymphocytes (sTILs) are associated with a better response to neoadjuvant chemotherapy and improved prognosis in all molecular subtypes of female breast cancer, but their role in MBC is less clear. We studied sTILs and the expression of programmed cell death ligand 1 (PD-L1) and pan-TRK in MBC.
