In our cohort of HR+/HER2- early BC patients, patient menopausal status influenced the correlation between the RS and classical histopathological features. The rate of PgR expression was the only variable consistently correlating with the RS, regardless of menopausal status. Hence, the prognostic and predictive role of this, often overlooked, parameter deserves further investigation in larger and multicentric cohorts, along with a prospective validation.

Methods Pre/perimenopausal pts with no prior systemic therapy for aggressive HR+/HER2− ABC were randomized 1:1 to RIB + letrozole/anastrozole + goserelin or physician's choice of combo CT. Contrary results in the CT arm suggest that these signatures warrant further studies on their potential predictive value. These data are hypothesis generating and should be interpreted with caution due to small sample sizes.

Subsequently, he received androgen deprivation therapy (ADT) for 6 months with triptorelin and bicalutamide...The pathological stage was pT1c pN1mi.The Oncotype DX study had a Recurrence Score (RS) of 22 points, leading to a recommendation for adjuvant chemotherapy with Docetaxel-Cyclophosphamide for 4 cycles, followed by tamoxifen...Early detection through screening and appropriate medical follow-up improves the prognosis in patients carrying PV in BRCA2. Therefore, risk control monitoring and adequate genetic counseling are necessary.

In breast cancers, there is no resistance to genotoxic or immune blocker therapies, but rather, the nonresponsive tumor cells exhaust all compensatory possibilities against therapeutic damages. Understanding the behavior and ambition of breast cancer cells may achieve a turn in therapy via applying supportive care instead of genotoxic measures.

The conditional factor induced by ADA@MOF-EPL further enhances the antitumor efficacy while significantly reducing systemic toxicity. Moreover, ADA@MOF-EPL demonstrates similar antitumor abilities in other p53-mutated solid tumors, revealing its potential as a broad-spectrum antitumor drug.

Clinical assessments suggested diagnostic value for GRPR-targeted theranostics in breast cancer patients, particularly those with high estrogen receptor expression. Nevertheless, in the therapeutic clinical context, paying attention to the radiation dose administered to the pancreas and kidneys is crucial.

The use of steroids and/or antibiotics in the patient prior to sampling can also impact the likelihood of success in PDX development. Lastly, establishing a cutoff point for tumor growth rates could guide the decision-making process during PDX development.

The putative worse prognostic impact of HER2 expression in pts with ER-positive/HER2-negative BCs was not confirmed. The better outcome observed in pts with HER2 2+/FISH- BCs may be related to the known FISH-negative (HER2-non-amplified) status of this subgroup. These findings may help identify optimal patient inclusion criteria for clinical trials with novel anti-HER2 therapies in ER-positive/HER2-negative disease.

Our study shows that PABC is potentially a clinical and molecular different entity with predominance of the basal-like subtype. Moreover, our results suggest the activation of oncogenic pathways related to cell proliferation, DNA damage repair and p53 mutations which may lead to a clinically more aggressive phenotype for PABC patients. Likewise, the enrichment of BRCAness and HRD signatures found in PABC patients in our study may suggest an increased genetic instability due to a breakdown in the DNA damage repair.

Curcumin potentiated the apoptotic effect of venetoclax in NT1-M CLL cells...These cellular effects were associated with reduced NOTCH1 activity in leukemic cells and resulted in prolonged survival of curcumin-treated mice. Overall, our results indicate that ER stress induction in NT1-M CLL might represent a new therapeutic opportunity for these high-risk CLL patients and improve the therapeutic effect of drugs currently used in CLL.

Several drugs have been designed to specifically target ER in ER-positive (ER+) breast cancer, including selective estrogen receptor modulators (SERM) such as Tamoxifen...This paper provides a comprehensive review of the structural functions of ER and highlights recent advancements in SERD and SERCA-related small molecule drugs, especially focusing on their structural optimization strategies and future optimization directions. Additionally, the therapeutic potential and challenges of novel SERDs and SERCAs in breast cancer and other ER-related diseases have been discussed.

We found that HR+ breast cancer cell lines treated with the selective estrogen-degrader fulvestrant, displayed increased B7-H4 levels and combination treatment of EVOLVE-106 with fulvestrant increases EC50 of tumor killing by 5–8 fold. Conclusions These data support the potential positioning of EVOLVE-106 as a first-in-category immunotherapeutic approach for patients with Her2 receptor low breast cancers, and both estrogen receptor positive and negative tumors, including TNBC.
