CDK4/6 inhibitor therapy in hormone receptor-positive breast cancer is linked to increased corneal epithelial alterations, including punctate epitheliopathy and vortex keratopathy, independent of aromatase inhibitor effects or tear film dys
This review synthesizes the BRIGHT-2 trial findings and meta-analytical data, confirming that bireociclib plus fulvestrant significantly improves progression-free survival in HR+/HER2- advanced breast cancer.
The Phase 3 SONIA trial demonstrates that delaying CDK4/6 inhibitors to the second-line setting for advanced breast cancer yields comparable overall survival to first-line use, while significantly reducing treatment-related toxicities and h
A phase 2 trial demonstrates that combining letrozole, abemaciclib, and metformin achieves a 32% response rate and 60% clinical benefit rate in ER+ endometrioid endometrial cancer, with notable efficacy in CTNNB1-mutated tumors and an inter
The phase 3 SONIA trial demonstrates that initiating CDK4/6 inhibitors in the first-line setting does not improve overall survival compared to second-line use in HR-positive, ERBB2-negative advanced breast cancer, while significantly increa
The Phase 3 PATINA trial demonstrates that adding palbociclib to maintenance anti-HER2 and endocrine therapy significantly improves progression-free survival in HR+/HER2+ metastatic breast cancer patients, increasing the median duration fro
The GOG 3026 phase II trial demonstrates that the combination of ribociclib and letrozole provides significant clinical benefit and durable responses in patients with recurrent low-grade serous carcinoma, representing a major step forward f
The CARABELA trial suggests that while neoadjuvant abemaciclib plus letrozole did not meet the threshold for similarity to chemotherapy in highly proliferative HR+/HER2- breast cancer, it remains a viable alternative for patients with lower
This systematic review and network meta-analysis of 20 randomized trials demonstrate that molecular profiling for ESR1 and PI3K-AKT-PTEN alterations is essential for optimizing endocrine-based strategies after CDK4/6 inhibitor progression,
This study offers insights into the prevalence, characteristics, and long-term survival of breast cancer patients eligible for adjuvant CDK4/6 inhibitors, highlighting real-world outcomes compared to clinical trial populations.
Pretreatment circulating tumor DNA levels can predict which patients with advanced ER-positive, HER2-negative breast cancer benefit more from first-line CDK4/6 inhibitor therapy, supporting personalized treatment strategies.
