Currently, immunotherapy is considered as the fourth major modality of cancer treatment except surgery, chemotherapy and radiotherapy. The new therapeutic approach based on immune checkpoint inhibitors is a landmark innovation. Strategies considering checkpoint inhibitors have shown good anti-tumor effect by targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) or programmed cell death ligand 1 (PD-L1). Moreover, DNA mismatch repair-deficient tumors appear to be potential candidates for these therapies. This review summarizes the discussion and oral presentations in the annual meeting of American Society of Clinical Oncology (ASCO) and ASCO-gastrointestinal cancer (GI) in 2016 and provides an update on immunotherapy in gastrointestinal cancers.

Purpose: Nano-drug delivery systems (NDDS) have become a promising alternative and adjunctive strategy for lung cancer (LC) treatment. However, comprehensive bibliometric analyses examining global research efforts on NDDS in LC are scarce. This study aims to fill this gap by identifying key research trends, emerging hotspots, and collaboration networks within the field of NDDS and LC.

Inhibitors of the PD-1/PD-L1 immune checkpoint have revolutionized cancer treatment. However, the clinical response remains limited, with only 20% of patients benefiting from treatment and approximately 60% of PD-L1-positive patients exhibiting resistance. One key factor contributing to resistance is the externalization of phosphatidylserine (PS) on the surface of cancer cells, which suppresses immune responses and promotes PD-L1 expression, further hindering the efficacy of PD-L1 blockade therapies.

Background: Fulminant type 1 diabetes mellitus (FT1DM) is a severe subtype of type 1 diabetes characterized by rapid onset, metabolic disturbances, and irreversible insulin secretion failure. Recent studies have suggested associations between FT1DM and certain medications, warranting further investigation.
Objectives: This study aims to analyze drugs associated with an increased risk of FT1DM using the Food and Drug Administration Adverse Event Reporting System (FAERS) database.

: Immune-mediated colitis (IMC) is a common immune-related adverse event during immune checkpoint inhibitor (ICI) therapy. This case series and review aimed to highlight atypical cases of IMC and explore the potential of PET/CT to predict imminent ICI colitis. : Through a descriptive, retrospective study at a tertiary cancer center, we identified adult patients receiving ICIs for any cancer between 2010 and 2022 who also underwent PET/CT for routine cancer surveillance during this time.
