High-risk patients showed increased sensitivity to chemotherapeutic agents including Gallibiscoquinazole, Cisplatin, Axitinib, and Zoledronate. The anoikis-based risk model may serve as a useful prognostic tool for ACC. ARGs may contribute to ACC progression and are associated with immune microenvironment features, providing a potential basis for further mechanistic and translational studies.

This study evaluated the structural, electronic, pharmacokinetic, and receptor-binding properties of three bisphosphonate derivatives, alendronate, risedronate, and zoledronate, to investigate their therapeutic relevance in osteoporosis and breast cancer. Network analyses highlighted pathways related to mevalonate metabolism, hormone signaling, angiogenesis, extracellular matrix remodeling, and the RANK/RANKL/OPG axis. These findings support the potential repurposing of bisphosphonates, particularly zoledronate, for breast cancer-associated bone disease.

In vivo studies showed that osteoclast-specific rab7 conditional knockout mice exhibited osteopetrotic phenotypes. These findings provide insights into how BPs disrupt osteoclast function by blocking autophagy and suggest that targeting autophagy in osteoclasts could be a potential therapeutic approach for bone-related diseases.

Follow-up imaging during treatment showed marked reduction of the pericardial and pleural effusions, with improvement in arthralgia and activities of daily living. Although the benefit was transient, this case suggests that systemic chemotherapy in combination with bevacizumab may have contributed not only to temporary effusion control in advanced PEH but also to relief of PEH-associated HPOA, while concomitant zoledronic acid may also have supported symptom improvement.

Higher FLOT2 expression in nine HER2 amplified cell lines correlated with a higher T-DM1 IC50 in vitro , and breast cancer patients with high FLOT2 expression had worse survival when receiving either T-DXd (16.2 months (m) vs 18.3 m, p=0.04) or T-DM1 (38.0 m vs 41.3 m, p=0.1) in real-world Caris Life Sciences data. In conclusion, FLOT2 regulates the internalization and cytotoxicity of T-DM1 mediated by Cbl-dependent ubiquitination of HER2. Zoledronic acid disrupts the HER2/FLOT2 interaction, therefore increasing the internalization and cytotoxicity of T-DM1, providing proof of principle that a small molecule inhibitor of the HER2/FLOT2 interaction can enhance the activity of the HER2-targeting ADC.

This first comprehensive FAERS study identifies key drugs associated with ILI, including interferon β-1a, evolocumab, ofatumumab, interferon β-1b, and zoledronic acid. Clinical monitoring for drug-induced ILI is essential to enhance medication safety.

A 59-year-old woman with stage IIIA HR+/HER2- breast cancer underwent modified radical mastectomy in 2016, followed by adjuvant AC-P (doxorubicin hydrochloride 70 mg, cyclophosphamide 800 mg, and paclitaxel liposomes 180 mg) chemotherapy, radiotherapy, and letrozole maintenance...Since palbociclib was not yet covered by insurance, she received an initial chidamide + exemestane therapy, which proved ineffective. Using second-line palbociclib combined with fulvestrant and zoledronic acid therapy, disease stabilization was achieved for up to 12 months...As of September 2023, the patient has remained progression-free for >20 months and experienced only manageable grade 2 diarrhea. This case suggests that sequential CDK4/6 inhibition could help achieve >20 months of progression-free disease control in a patient with bone-only HR+/HER2- MBC after clinical progression during prior palbociclib-based therapy and underscored the need for biomarker-guided strategies in this distinct population.
