Importance: Current chemotherapy regimens for patients with ERBB2 (formerly HER2)-positive breast cancer are associated with considerable morbidity. These patients may benefit from more effective and less toxic therapies.

Objective: To evaluate the safety, immunogenicity, and preliminary efficacy of intratumoral (IT) delivery of conventional type 1 dendritic cells (cDC1) in combination with ERBB2-targeted therapies.

Trastuzumab-deruxtecan (T-DXd) has demonstrated intracranial efficacy; however, safety and efficacy data remains limited with stereotactic radiosurgery (SRS). A multi-institutional review was performed with HER2+ or HER2-low metastatic breast cancer treated with T-DXd and SRS for active brain metastases. We identified 215 lesions treated over 48 SRS courses in 34 patients.

Article Synopsis
  • - The study aimed to understand MRI imaging patterns in breast cancer patients undergoing neoadjuvant immunotherapy, particularly focusing on responses to various combinations of chemotherapy and immunotherapy in the I-SPY2 clinical trial.
  • - Out of 43 patients analyzed, 44.4% receiving the chemo-immunotherapy experienced increased lymphadenopathy in the first 12 weeks, significantly higher compared to just 6.3% in the control group, with most cases linked to the SD-101 and pembrolizumab treatment.
  • - Despite observing increased lymphadenopathy in some patients, this was not associated with a higher incidence of positive lymph nodes at surgery, even as breast tumor sizes decreased over time.

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with a poor prognosis particularly in the metastatic setting. Treatments with anti-programmed cell death protein-1/programmed death-ligand 1 (PD-L1) immune checkpoint inhibitors (ICI) in combination with chemotherapies have demonstrated promising clinical benefit in metastatic TNBC (mTNBC) but there is still an unmet need, particularly for patients with PD-L1 negative tumors. Mechanisms of resistance to ICIs in mTNBC include the presence of immunosuppressive tumor-associated macrophages (TAMs) in the tumor microenvironment (TME).

Neuroinflammation contributes to the pathogenesis of several neurodegenerative disorders. This study examined the neuroprotective effect of quercetin (QUR)-loaded poly (lactic-co-glycolic) acid (PLGA) nanoparticles (QUR NANO) against the neurotoxicity induced by lipopolysaccharide (LPS) in mice. A QUR NANO formulation was prepared and characterized by differential scanning calorimetry, X-ray diffraction, entrapment efficiency (EE), high-resolution transmission electron microscopy, field emission scanning electron microscopy, and drug release profile.

Postprocessing is essential for improving titanium aluminide (TiAl) microstructure and part quality after using the laser powder bed fusion (L-PBF) method. It has been reported that Ti-48Al-2Cr-2Nb (%at) processed by L-PBF has internal defects and low fracture toughness. Microstructure control by heat treatment (HT) showed a significant improvement in the ductility of the material.

Purpose: HER2-positive breast cancer has a high risk of brain metastasis. Stereotactic radiosurgery (SRS) is standard of care for limited brain metastases. Tucatinib, a HER2-targeted tyrosine kinase inhibitor, has demonstrated intracranial efficacy in the HER2-CLIMB Trial.

Background: The genus Huffmanela Moravec, 1987 (Nematoda, Trichosomoididae, Huffmanelinae), represents a group of nematodes that infect both marine and freshwater fish, and the main gross feature of infection with different species of the genus is the presence of noticeable dark spots or tracks within the parasitized tissues. The purpose of this study was to describe morphologically and morphometrically the eggs of a new marine species of Huffmanela (Huffmanela persica sp. nov.

In the past decade, defective DNA repair has been increasingly linked with cancer progression. Human tumors with markers of defective DNA repair and increased replication stress exhibit genomic instability and poor survival rates across tumor types. Seminal studies have demonstrated that genomic instability develops following inactivation of BRCA1, BRCA2, or BRCA-related genes.

Among high-risk breast cancer (BC) survivors, genetic counseling (GC) and genetic testing (GT) may inform cascade testing and risk management. Compared to non-Hispanic White BC survivors, Spanish-preferring Latina BC survivors are less likely to report discussing GC with a healthcare provider. However, few studies have examined Latinas' experiences with GC/GT, particularly outside of the mainland USA.

Aims: To assess the level of transesophageal echocardiography (TOE) knowledge and skills of young cardiologists.

Methods And Results: A European Association of Cardiovascular Imaging (EACVI) online study using the first fully virtual simulation-based software was conducted in two periods (9-12 December 2021 and 10-13 April 2022). All young cardiologists eligible to participate (<40 years) across the world were invited to participate.

Compared with non-Hispanic White women, Latina women are less likely to receive genetic counseling (GC) and testing (GT) following BC diagnosis. This study used secondary data analysis to explore beliefs about GC among Latina BC survivors in and outside the US mainland. GC/GT-naïve, high-risk, Spanish-preferring Latina BC survivors (n = 52) in FL and PR completed the Behavioral Beliefs about GC scale.

The treatment of metastatic breast cancer (mBC) has evolved significantly in the past several years with the approval of new targeted agents. Trastuzumab deruxtecan (T-DXd), an antibody-drug conjugate with a topoisomerase I inhibitor payload, is a new addition to the class of therapies that target the human epidermal growth factor 2 (HER2) receptor. T-DXd was approved in the US in December 2019 for patients with HER2-positive metastatic or unresectable breast cancer who have received 2 or more prior anti-HER2-based regimens in the metastatic setting.

Patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer are at a particularly high risk of breast cancer brain metastasis (BCBM) and leptomeningeal disease (LMD). Improvements in systemic therapy have translated to improved survival for patients with HER2-positive BCBM and LMD. However, the optimal management of these cases is rapidly evolving and requires a multidisciplinary approach.

Purpose: PIK3CA and ESR1 mutations have been implicated in resistance to endocrine therapy (ET) in HR+, HER2- advanced breast cancer (ABC). Inhibition of CDK4 and 6 has been hypothesized as a therapeutic strategy to overcome endocrine resistance in patients with PIK3CA- or ESR1-mutant breast cancers. The objective of this exploratory analysis was to assess efficacy of abemaciclib plus fulvestrant in patients with or without PIK3CA or ESR1 mutations in MONARCH 2.

Purpose: We hypothesize treatment with nivolumab and stereotactic radiosurgery (SRS) will be feasible and well tolerated, and may improve intracranial tumor control rates compared with SRS alone.

Methods And Materials: The study was designed as a prospective, single-arm, nonrandomized, open-label, phase 1b trial of nivolumab and SRS among patients with metastatic breast cancer brain metastases. Key eligibility criteria included patients with breast cancer brain metastases of all subtypes, age ≥18, Eastern Cooperative Oncology Group Performance Status ≤2 with ≤10 brain metastases.
