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.
Background: Oligometastatic breast cancer (OMBC) is a clinical entity with a prospect of long-term survival, but uncertainty remains on its optimal treatment. We studied whether intensified alkylating chemotherapy (IACT) improves long-term outcome compared to conventional-dose chemotherapy (CDCT) as part of a multimodality approach for patients with OMBC harboring homologous recombination deficiency (HRD).
Patients And Methods: Eligible patients had HER2-negative OMBC, harboring HRD, with ≤ 3 distant metastases, pathologic proof of distant disease and a favorable response to three cycles CDCT.
Efficacy of Pembrolizumab and Biomarker Analysis in Patients with WGS-Based Intermediate to High Tumor Mutational Load: Results from the Drug Rediscovery Protocol.
Clin Cancer Res
September 2024
Purpose: To evaluate the efficacy of pembrolizumab across multiple cancer types harboring different levels of whole-genome sequencing-based tumor mutational load (TML; total of nonsynonymous mutations across the genome) in patients included in the Drug Rediscovery Protocol (NCT02925234).
Patients And Methods: Patients with solid, treatment-refractory, microsatellite-stable tumors were enrolled in cohort A: breast cancer cohort harboring a TML of 140 to 290, cohort B: tumor-agnostic cohort harboring a TML of 140 to 290, and cohort C: tumor-agnostic cohort harboring a TML >290. Patients received pembrolizumab 200 mg every 3 weeks.
Background: Guidelines for oligometastatic breast cancer (OMBC) propagate multimodality treatment including polychemotherapy and local ablative treatment (LAT) of all lesions. The aim of this approach is prolonged disease remission, or even cure. Long-term outcomes in OMBC and factors associated with prognosis are largely unknown, due to the rarity of this condition.

In this cross-sectional study nested in a breast cancer cohort, we investigated the association between AI exposure and early markers for cardiovascular disease in BC survivors.
Methods: The study population consisted of 569 women, who were 5-7 years (n = 277) or 10-12 years (n = 292) after BC diagnosis.
