A Multi-marker model based on serum IL-10 predicts response to conversion immunochemotherapy in gastric cancer patients: a retrospective cohort study.

Background: Conversion immunochemotherapy may enable curative surgery in patients with initially unresectable locally advanced gastric cancer, but its response rate remains low. Little evidence has shown how to easily predict therapeutic efficacy from hematological biomarkers, apart from tissue biomarkers. This study aimed to identify predictive factors for treatment response from hematological biomarkers and propose strategies for non-responsive patients.

Targeting SIX2 as a novel sensitization strategy of sorafenib treatment on advanced hepatocellular carcinoma through modulating METTL9-SLC7A11 axis.

Sorafenib is the main treatment for advanced hepatocellular carcinoma (HCC), but drug resistance limits its effectiveness. Evidence increasingly indicates that, in addition to targeting tyrosine kinases, sorafenib also induces ferroptosis. However, current studies have not fully clarified the relationship between ferroptosis and sorafenib treatment sensitivity.

Expression Patterns of Immune Checkpoint Molecules and Their Clinical Values in Gastric Neuroendocrine Neoplasms.

Introduction: Gastric neuroendocrine neoplasms (g-NENs) are a rare type of stomach tumor. However, limited data exist about the expression and clinical significance of B7 family ligands/receptors in patients with g-NENs. Thus, we conducted this study to address this issue in a cohort of 112 patients with g-NENs.

Infiltrating characteristics and prognostic value of tertiary lymphoid structures in resected gastric neuroendocrine neoplasm patients.

Objectives: Tertiary lymphoid structures (TLSs) are lymphocyte aggregates that play an anti-tumor role in most solid tumors. However, the functions of TLS in gastric neuroendocrine neoplasms (GNENs) remain unknown. This study aimed to determine the characteristics and prognostic values of TLS in resected GNEN patients.

Tissue-resident memory T cells in gastrointestinal tumors: turning immune desert into immune oasis.

Tissue-resident memory T cells (Trm) are a particular type of T cell subgroup, which stably reside in tissues and have been revealed to be the most abundant memory T cell population in various tissues. They can be activated in the local microenvironment by infection or tumor cells and rapidly clean them up to restore homeostasis of local immunity in gastrointestinal tissues. Emerging evidence has shown that tissue-resident memory T cells have great potential to be mucosal guardians against gastrointestinal tumors.

Turning Tertiary Lymphoid Structures (TLS) into Hot Spots: Values of TLS in Gastrointestinal Tumors.

Tertiary lymphoid structures (TLSs) are ectopic lymphocyte aggregation structures found in the tumor microenvironment (TME). Emerging evidence shows that TLSs are significantly correlated with the progression of gastrointestinal tumors, patients' prognosis, and the efficacy of adjuvant therapy. Besides, there are still some immunosuppressive factors in the TLSs that may affect the anti-tumor responses of TLSs, including negative regulators of anti-tumor immune responses, the immune checkpoint molecules, and inappropriate tumor metabolism.
