Pyroptosis plays a crucial role in immune responses. However, the effects of pyroptosis on tumor microenvironment remodeling and immunotherapy in gastric cancer (GC) remain unclear. Large-sample GEO data (GSE15459, GSE54129, and GSE62254) were used to explore the immunoregulatory roles of pyroptosis.

Previous studies have demonstrated that the tumor microenvironment (TME) dominates immunotherapy; therefore, an effective TME classification strategy is required. In this study, five crucial immunophenotype-related molecules (WARS, UBE2L6, GZMB, BATF2, and LAG-3) in the TME are determined in five public gastric cancer (GC) datasets (n = 1426) and an in-house sequencing dataset (n = 79).

However, its role, underlying mechanisms, and prognostic significance in human gastric cancer (GC) are elusive. Here, we obtained GC tissues and corresponding normal tissues from 48 patients and identified LHPP as a downregulated gene via RNA-seq.
View Article and Find Full Text PDFImmunosuppressive molecules are extremely valuable prognostic biomarkers across different cancer types. However, the diversity of different immunosuppressive molecules makes it very difficult to accurately predict clinical outcomes based only on a single immunosuppressive molecule. Here, we establish a comprehensive immune scoring system (ISS) based on 6 immunosuppressive ligands (NECTIN2, CEACAM1, HMGB1, SIGLEC6, CD44, and CD155) using the LASSO method to improve prognostic accuracy and provide an additional selection strategy for adjuvant chemotherapy of gastric cancer (GC).

Purpose: Apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3B (APOBEC3B) is a recently discovered protein that is considered important in causing mutations in tumor cell genome bases. Whether APOBEC3B is expressed in nasopharyngeal carcinoma (NPC) still remains unknown. Studies have shown that programmed-cell-death receptor-1 ligand (PD-L1) is highly expressed in NPC, but its clinical significance has not been fully elucidated.

Objective: This study aims to investigate differences in the metabolomic profiles of patients who received different surgeries for papillary thyroid carcinoma (PTC).
Methods: Two surgical methods, i.e.
Background Or Purpose: This study was designed to determine the value of AJCC staging 7th edition and improved AJCC staging in assessing the prognosis of gastric neuroendocrine carcinoma (GNEC).
Methods: In total, GNEC 475 patients in the Surveillance, Epidemiology, and End Results (SEER) database and 129 GNEC patients in our department undergoing resection were included. The former served as the test group, and the latter served as the validation group.
Background: The presence and the prognostic significance of perigastric tumor deposits (TDs) in primary gastric cancer have not been extensively studied. The aim of this study was to evaluate the prognostic significance perigastric TDs in primary gastric cancer.
Methods: From 2005 to 2010, 1250 patients underwent R0 gastrectomy at the Department of Gastric Surgery, Fujian Medical University Union Hospital, Fuzhou, China.
Objective: Analysis of the metabolic differences among the papillary thyroid carcinoma (group T) patients, benign thyroid tumor patients (group B) and healthy controls (group H) by nuclear magnetic resonance hydrogen spectrum.
Methods: collect twenty serum specimens each from group T, group B and group H. Collect image archive.
Aims And Background: Locally advanced rectal adenocarcinoma is typically treated with neoadjuvant chemoradiotherapy and surgery. We assessed the effect of an additional cycle of capecitabine/oxaliplatin chemotherapy before surgery in 57 patients with T3/4, N+/- or T1/2, N+ rectal cancer. MATERIALS AND STUDY DESIGN: Radiotherapy (total dose, 50.

Methods: Twenty-nine non-obese patients with type 2 diabetes mellitus underwent sleeve gastrectomy with ileal interposition duodenojejunal bypass operation. All the patients were subjected to the measurement of total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), homeostatic model assessment for insulin resistance (Homa-IR), glycosylated hemoglobin (HbA1c) at postoperative 12th month.
Objective: To investigate the impact of expression of kisspeptin-1 (KiSS-1) metastasis-suppressor gene on the proliferative, adhesive and invasive abilities of human hepatocellular carcinoma (HCC) using an in vitro cell system.
