Article Synopsis
- CDK4/6 inhibitors combined with endocrine therapy improve outcomes for patients with hormone-receptor positive, HER2-negative advanced breast cancer, but evidence comparing first-line and second-line use is limited.
- The phase 3 SONIA trial involved 1,050 patients and showed no significant overall benefit for using CDK4/6 inhibitors first-line compared to second-line (31.0 vs. 26.8 months median progression-free survival).
- Although first-line treatment led to longer duration of CDK4/6 therapy and more severe side effects, the quality of life was similar for both treatment timing, questioning the necessity for first-line CDK4/6 inhibitor usage in all cases.
The primary objective of the prospective, randomized, multicenter, phase 3 biomarker Microarray Analysis in breast cancer to Taylor Adjuvant Drugs Or Regimens trial (MATADOR: ISRCTN61893718) is to generate a gene expression profile that can predict benefit from either docetaxel, doxorubicin, and cyclophosphamide (TAC) or dose-dense scheduled doxorubicin and cyclophosphamide (ddAC). Patients with a pT1-3, pN0-3 tumor were randomized 1:1 between ddAC and TAC. The primary endpoint was a gene profile-treatment interaction for recurrence-free survival (RFS).

However, it remains unclear if TILs could be a prognostic and/or predictive biomarker in the context of dual HER2-targeting treatment. In this study, we evaluated the association between TILs and pathological response (pCR) and invasive-disease free survival (IDFS) in 389 patients with stage II-III HER2 positive breast cancer who received neoadjuvant anthracycline-containing or anthracycline-free chemotherapy combined with trastuzumab and pertuzumab in the TRAIN-2 trial.

A more personalized approach, based on patients' individual risk of recurrence and personal needs and preferences, may reduce patient burden and reduce (healthcare) costs. The NABOR study will examine the (cost-)effectiveness of personalized surveillance (PSP) and personalized aftercare plans (PAP) on patient-reported cancer worry, self-rated and overall quality of life and (cost-)effectiveness.
