HR positive

In conclusion, this randomized clinical trial met its primary outcome. Culmerciclib plus fulvestrant is well tolerated and leads to a significant gain in PFS of pretreated HR-positive HER2-negative ABC patients.

ET+CDK4/6i use rose up to ∼50 % after 2017, reaching ∼70 % in recent years among women with good PS, but remained ∼50 % in older patients with poor PS. Broader adoption is needed, with less chemotherapy use. Survival outcomes have improved but, causality cannot be confirmed due to the observational design.

Inpatient glucose monitoring enabled prompt detection of rapid glucose elevation and early intervention before the onset of DKA, resulting in a favorable outcome. Further clinical evidence is required to define optimal intervention strategies for grade 4 hyperglycemia associated with capivasertib therapy.

Early findings suggest letrozole is well tolerated and may represent a viable therapeutic option for hormone receptor-positive LGSCO. Ongoing molecular and clinical analyses will clarify its role in this rare subtype.

This benefit was confirmed in a multivariable analysis, supporting PARPi as the preferred option in eligible patients. Our findings suggest that PARPi should be prioritized in the post-CDK4/6i treatment sequence for BRCA LP/PV carriers with HR+/HER2 aBC and highlight the critical role of germline BRCA testing.

Omission of SLNB in patients with small HR-positive/HER2-negative tumors results in a missed indication for CDK4/6i in <8 % with minimal impact on recurrence.

Antiestrogen therapy in HR + breast cancer patients induces progressive ocular surface dysfunction, driven by chronic inflammation and epithelial damage. These findings highlight the importance of recognizing ocular symptoms in this population and support further studies evaluating the role of routine ophthalmologic monitoring in survivorship care.

OFS + AI were associated with better DDFS in patients with RD after neoadjuvant therapy. Our findings can assist shared decision-making on adjuvant endocrine therapy of these patients.

Clinical data indicate a higher incidence of nephrotoxic adverse reactions in patients receiving CDK4/6i compared to control groups, with abemaciclib showing the highest risk ratio...Preclinical studies suggest a complex effect on renal health; while some data indicate acute nephroprotection, long-term rodent models treated with palbociclib after ischemic AKI demonstrated impaired recovery, increased renal fibrosis, and cellular senescence, indicating potentially detrimental long-term chronic effects...Furthermore, these agents are susceptible to significant drug-drug interactions, particularly with CYP3A4 inhibitors/inducers and immunosuppressants, necessitating careful dose adjustments and monitoring, especially in solid organ transplant recipients. This review consolidates current evidence regarding the renal of CDK4/6i, emphasizing the need for vigilant monitoring and a multidisciplinary approach to optimize patient outcomes.

This meta-analysis reinforces the importance of molecular stratification in treatment decisions after CDK4/6i progression, highlighting the need for efficacy and safety assessments across biomarker-selected subgroups.

Ribociclib plus letrozole met the primary end point, achieving meaningful response rates and durable disease control in recurrent LGSOC. The safety profile was consistent with prior CDK4/6 inhibitor studies. This combination represents a therapeutic option in this rare and genomically distinct subtype.

We report a rare case of OBC diagnosed based on a solitary scalp metastasis without ALNM. OBC without ALNM appears to favor luminal type and distinct metastatic sites, but further cases are needed to establish treatment strategies.
