SERENA-3 demonstrates that camizestrant 75 mg once daily (Phase III dose) is well-tolerated and achieves maximal reduction in ER through known mechanisms, that is, antagonism and degradation, by 5-7 days, and proliferation suppression determined by Ki67 expression, by 12-15 days. These data support camizestrant 75 mg once daily as the preferred dose for ongoing clinical development and highlight the importance of presurgical WOO studies in guiding dose selection.

Among the most studied SERMs are Tamoxifen and Raloxifene. The pharmacological profile of SERMs therefore reflects a delicate equilibrium between receptor-mediated vascular protection and thrombotic liability. Indeed, their raison d'être increasingly extends beyond oncology into cardiovascular endocrine pharmacology, where they serve as prototypes for designing next-generation agents with optimized receptor selectivity and safer vascular outcomes.

Drug sensitivity analyses suggested that high-risk GBM may respond better to paclitaxel and tamoxifen. Random Forest modeling and in vitro experiments identified GJB2 as an oncogenic driver that promotes GBM cell proliferation and migration. Our findings provide a clinically applicable EMT-based prognostic framework that links transcriptional plasticity to patient outcomes in GBM and identify GJB2 as a promising therapeutic target.

Our results may establish evidence supporting the omission of adjuvant chemotherapy in premenopausal women with low genomic risk scores and limited nodal involvement (p-N1), potentially reducing treatment-related morbidity while preserving comparable oncologic outcomes.

Data were leveraged from preclinical and phase I/II studies in metastatic and early breast cancer, as a single agent and with palbociclib, to inform giredestrant dose selection. Our learnings challenge the MTD paradigm in drug development, particularly in targeted therapies, and demonstrate the importance of basing dose selection on the totality of evidence, including preclinical data, and may help inform the clinical development of future targeted therapies.

In vitro functional assays demonstrated that either DHCR7 knockdown or treatment with the targeted inhibitor tamoxifen significantly suppressed AML cell proliferation...Mechanistic investigations further revealed that DHCR7 exerts pro-leukaemic effects through activation of the IL-6/JAK2/STAT3 signalling axis. Collectively, this study establishes the novel function of DHCR7 in AML pathogenesis and provides robust evidence supporting its potential as a therapeutic target for AML.

Oncotype diagnosis (DX) testing indicated a low chemotherapy benefit, leading to adjuvant therapy with tamoxifen...The prompt detection of the suspicious mass, culminating in effective early-stage treatment, proved crucial to this patient's favorable prognosis, in contrast to the common trend of delayed diagnoses and their less promising outcomes. Accordingly, strengthening public awareness and professional training is essential to optimize management and improve outcomes in men with breast cancer.

Further, inhibition of EZH2 in vitro resulted in increased expression of ER in HER2+ human breast cancer cell lines and conferred sensitivity to Tamoxifen. These findings demonstrate that EZH2 dictates cancer plasticity and provides rationale for combining EZH2 inhibitors with endocrine therapies to improve HER2+ breast cancer outcomes.

Furthermore, coadministration of tamoxifen and the EGFR TKI gefitinib potentially inhibited p-EGFR expression in EGFR-mutant lung adenocarcinoma. Regular follow-up with chest computed tomography is recommended for patients with breast cancer. For those diagnosed with both ER-positive breast cancer and EGFR-mutant lung adenocarcinoma, combined tamoxifen and EGFR TKI therapy may offer an effective targeted treatment strategy.

The results in terms of PFS and AEs are consistent with those of pivotal studies and real clinical practice data, but a direct comparison is not possible due to differences in patient populations. Ribociclib once again demonstrated efficacy in all patient subgroups and remains the gold standard, alongside ET, for first-line HR+/HER2-negative mBC.
