Nivolumab and stereotactic radiosurgery for patients with breast cancer brain metastases: long-term results and biomarker analysis from a non-randomized, open-label, phase Ib study

Background
We hypothesized treatment with nivolumab and stereotactic radiosurgery (SRS) would be feasible, well tolerated, and may improve intracranial tumor control over SRS alone for breast cancer brain metastases (BCBM).

Methods
The study is a pha…

Intratumoral microbiota predicts the response to neoadjuvant chemoimmunotherapy in triple-negative breast cancer

Background
Neoadjuvant immunotherapy combined with chemotherapy (Chemo-IM) is associated with significantly improved pathological complete response (pCR) rates and long-term survival outcomes in patient with early-stage triple-negative breast cancer (…

Onset and progression of atherosclerosis in patients with melanoma treated with immune checkpoint inhibitors

Background
Immune checkpoint inhibitors (ICIs) are effective anticancer agents but significantly increase cardiovascular risk. This could be due to its potential to induce or worsen atherosclerosis. We evaluated the onset and progression of atheroscle…

Gut microbiota derived indole-3-acetic acid ameliorates precancerous inflammatory intestinal milieu to inhibit tumorigenesis through IL-35

Background
Gut microbiota can significantly alter the risk or progression of cancer by maintaining gut immune system homeostasis. However, the exact mechanism by which the gut microbiota and its metabolites influence colorectal tumorigenesis is unclea…

Novel PD-1-targeted, activity-optimized IL-15 mutein SOT201 acting in cis provides antitumor activity superior to PD1-IL2v

Background
SOT201 and its murine surrogate mSOT201 are novel cis-acting immunocytokines consisting of a humanized/murinized/, Fc-silenced anti-programmed cell death protein 1 (PD-1) monoclonal antibody (mAb) fused to an attenuated human interleukin (I…

CD22-targeted chimeric antigen receptor-modified T cells for children and adults with relapse of B-cell acute lymphoblastic leukemia after CD19-directed immunotherapy

Background
Relapse of B-cell acute lymphoblastic leukemia (B-ALL) with CD19-antigen loss after CD19-targeted chimeric antigen receptor (CAR) T-cell therapy has a dismal prognosis. Novel immunotherapeutic strategies for this patient population are urge…

Shp-1 regulates the activity of low-affinity T cells specific to endogenous self-antigen during melanoma tumor growth and drives resistance to immune checkpoint inhibition

Background
The presence of activated CD8 T cells in the tumor microenvironment is correlated with an effective immune response to immune checkpoint inhibitor (ICI) therapy. However, ICI predominantly targets high-affinity T cells, which may be less ab…

METTL3 promotes an immunosuppressive microenvironment in bladder cancer via m6A-dependent CXCL5/CCL5 regulation

Background
Bladder cancer (BLCA) is a challenging malignancy with a poor prognosis, particularly in muscle-invasive cases. Despite recent advancements in immunotherapy, response rates remain suboptimal. This study investigates the role of METTL3, an m…
