Structural inequities have important implications for the health of marginalized groups. Neighborhood-level redlining and lending bias represent state-sponsored systems segregation, potential drivers adverse outcomes. We sought to estimate effect on breast cancer mortality explore differences by race.

BACKGROUND As systemic therapy has improved for locally advanced pancreatic cancer (LAPC), efforts to improve local control with optimal radiotherapy may be critical. Although conventionally fractionated radiation (CFRT) more recently shown a limited role in LAPC, stereotactic body (SBRT) is an emerging approach promising results. With no studies date comparing SBRT CFRT this study used the National Cancer Data Base (NCDB) evaluate these 2 modalities. METHODS NCDB, patients American Joint...

Glioblastoma (GBM) is the most aggressive malignant primary brain tumor in adults, with a median survival of 14.6 months. Recent efforts have focused on identifying clinically relevant subgroups to improve our understanding pathogenetic mechanisms and patient stratification. Concurrently, role immune cells microenvironment has received increasing attention, especially T tumor-associated macrophages (TAM). The latter are mixed population activated brain-resident microglia infiltrating...

We retrospectively compared the outcomes and toxicities of melanoma brain metastases (MBM) patients treated with BRAF inhibitors (BRAFi) stereotactic radiosurgery (SRS) SRS alone. identified 87 157 MBM alone from 2005 to 2013. Of these, 15 (17.2%) 32 (21.4%) received BRAFi therapy: three (20.0%) before SRS, two (13.3%) concurrent, 10 (66.7%) after SRS. Overall survival (OS) was between cohorts using product limit method.

Background Individuals of advanced age with comorbidities face a higher risk death from coronavirus disease 2019 (COVID‐19), especially once they are ventilator‐dependent. Respiratory decline in patients COVID‐19 is precipitated by lung‐mediated aberrant immune cytokine storm. Low‐dose lung radiation was used to treat pneumonia the pre‐antibiotic era. Radiation immunomodulatory effects may improve outcomes for select COVID‐19. Methods A single‐institution trial evaluating safety and efficacy...

Commonly used first-line (1L) treatments for mantle cell lymphoma include high-dose cytarabine-based induction followed by autologous stem-cell transplant (ASCT) younger patients and several chemoimmunotherapy regimens older patients. Continuous debates exist on the role of ASCT in maintenance rituximab (MR) after bendamustine plus (BR).Retrospective data from 4,216 with Flatiron Health electronic record-derived deidentified database diagnosed between 2011 2021, mostly US community oncology...

Vaccine-induced neutralizing antibodies (nAbs) play a critical role in protection from SARS CoV-2. Patients with B-cell malignancies including myeloma are at increased risk of COVID-19-related mortality and exhibit variable serologic response to the vaccine. The capacity vaccine-induced these patients neutralize CoV-2 or its variants is not known.Sera 238 multiple (MM) undergoing vaccination were analyzed. Antibodies against spike receptor-binding domain (RBD) viral nucleocapsid measured...

Abstract Paediatric high-grade gliomas (HGGs) account for the most brain tumour-related deaths in children and have a median survival of 12–15 months. One promising avenue research is development novel therapies targeting properties non-neoplastic cell-types within tumour such as associated macrophages (TAMs). TAMs are immunosuppressive promote malignancy adult HGG; however, paediatric medulloblastoma, exhibit anti-tumour properties. Much known about HGG, yet little them setting. This raises...
