Body mass index and type 2 diabetes mellitus as metabolic determinants of immune checkpoint inhibitors response in melanoma

Background
Immune checkpoint inhibitors (ICIs) have improved survival outcomes in melanoma. Studies exploring the correlations between body mass index (BMI), type 2 diabetes (T2DM) and the outcomes of ICI treatment have yielded inconsistent results. I…

TMED inhibition suppresses cell surface PD-1 expression and overcomes T cell dysfunction

Background
Blockade of the programmed cell death protein 1 (PD-1) immune checkpoint (ICB) is revolutionizing cancer therapy, but little is known about the mechanisms governing its expression on CD8 T cells. Because PD-1 is induced during activation of…

WWOX tuning of oleic acid signaling orchestrates immunosuppressive macrophage polarization and sensitizes hepatocellular carcinoma to immunotherapy

Background
Immune checkpoint inhibitors (ICIs) are therapeutically effective for hepatocellular carcinoma (HCC) but are individually selective. This study examined the role of specific common fragile sites (CFSs) related gene in HCC immunotherapy.

Me…

In situ endoscopic photodynamic therapy combined with immature DC vaccination induces a robust T cell response against peritoneal carcinomatosis

Background
Immunogenic cell death (ICD) and ferroptosis have recently emerged as key factors in the anticancer immune response. Among the treatments able to induce ICD and the associated release of danger signals is photodynamic therapy (PDT). Ferropt…

Role of CD47 gene expression in colorectal cancer: a comprehensive molecular profiling study

Background
In patients with colorectal cancer (CRC), the therapeutic effects of conventional immune checkpoint inhibitors targeting the adaptive immune system are largely limited to those with microsatellite instability-high tumors. Meanwhile, new imm…

Intratumoral and peritumoral radiomics of MRIs predicts pathologic complete response to neoadjuvant chemoimmunotherapy in patients with head and neck squamous cell carcinoma

Background
For patients with locally advanced head and neck squamous cell carcinoma (HNSCC), combined programmed death receptor-1 inhibitor and chemotherapy improved response rate to neoadjuvant therapy. However, treatment response varies among patien…

Cancer-associated fibroblasts shape early myeloid cell response to chemotherapy-induced immunogenic signals in next generation tumor organoid cultures

Background
Patient-derived colorectal cancer (CRC) organoids (PDOs) solely consisting of malignant cells led to major advances in the understanding of cancer treatments. Yet, a major limitation is the absence of cells from the tumor microenvironment, …

Reporting of late-onset immune-related adverse events with immune checkpoint inhibitors in VigiBase

Background
To date, evidence on late-onset immune-related adverse events (irAEs) with immune checkpoint inhibitors (ICIs) is limited to a small number of clinical cases. This study aimed to identify drug- and patient-related characteristics potentiall…

Myeloid subsets impede the efficacy of anti-PD1 therapy in patients with advanced gastric cancer (WJOG10417GTR study)

Background
Gastric cancer (GC) is one of the most common and deadly malignant diseases worldwide. Despite revolutionary advances, the therapeutic efficacy of anti-PD1/PDL1 monoclonal antibodies in advanced GC is still low due to the emergence of innat…

Multicenter validation of an RNA-based assay to predict anti-PD-1 disease control in patients with recurrent or metastatic head and neck squamous cell carcinoma: the PREDAPT study

Background
Despite advances in cancer care and detection, >65% of patients with squamous cell cancer of the head and neck (HNSCC) will develop recurrent and/or metastatic disease. The prognosis for these patients is poor with a 5-year overall survi…
