Attenuated immune surveillance during squamous cell transformation of pancreatic adenosquamous cancer defines new therapeutic opportunity for cancer interception

Background
Pancreatic adenosquamous cancer (PASC) is an extremely rare subtype of pancreatic cancer characterized by a poorer prognosis and higher likelihood of metastasis compared with the more prevalent pancreatic ductal adenocarcinoma (PDAC). Altho…

A real-world study on the efficacy and safety of low-dose PD-1 monoclonal antibody alone or in combination as the first-line treatment for advanced non-small cell lung cancer

Background
In clinical practice, patients with non-small cell lung cancer (NSCLC) often receive low-dose programmed death-1 (PD-1) monoclonal antibodies due to physical or financial limitations. However, the efficacy and safety of low-dose compared wi…

Programmed death-1 inhibition increases vaccine-induced T-cell infiltration in patients with prostate cancer

Background
Prostate cancer (PC) is the most frequently diagnosed cancer in men worldwide, making up 21% of all cancer cases. Although generally slow-growing, 370,000 men die from PC yearly. Immune checkpoint inhibitors (ICIs) are currently only indica…

STS2 deficiency revives CD8+T cells from exhaustion and augments checkpoint blockade efficacy in cancer immunotherapy

Background
T-cell exhaustion is a major barrier to effective antitumor immunity and limits the efficacy of cancer immunotherapies. This study investigates the role of suppressor of T-cell signaling 2 (STS2, also known as UBASH3A) in regulating CD8+ T-…

Hyperglycemia induces an immunosuppressive microenvironment in colorectal cancer liver metastases by recruiting peripheral blood monocytes through the CCL3-CCR1 axis

Background
The treatment of colorectal cancer liver metastasis (CRLM), a leading cause of mortality in patients with colorectal cancer, is complicated by type 2 diabetes (T2D). This study aimed to investigate the CRLM immune microenvironment in the co…
