Background And Objectives: Reports of clinicopathological features and prognosis in patients with mucinous gastric carcinoma (MGC) are conflicting. The aim was to describe the clinicopathological features and prognosis of patients with MGC in comparison with nonmucinous gastric carcinoma (NMGC).
Methods: We reviewed the records of 1,278 consecutive patients diagnosed with gastric carcinoma who were resected surgically from 1993 to 2003. Among them, 48 patients (3.8%) with MGC were compared to 1,230 patients with NMGC.
Results: There were significant differences in tumor location, stage of disease, lymphatic invasion, and vascular invasion between the patients with MGC and NMGC. The overall 5-year survival of patients with MGC was 27.2% as compared with 42.8% for patients with NMGC (P = 0.031). For the patients with the same stage, there was no significant difference between MGC and NMGC. With respect to patients with MGC, multivariate analysis showed that lymph node metastasis and curative resection were significant factors affecting survival.
Conclusions: MGC is rare and detected mostly in an advanced stage. Mucinous histology type itself is not an independent prognostic factor.

Background: Mucin family members have been reported to be widely expressed in gastric carcinoma with diverse functions. Several important mucins exert the function of tumorigenesis or progression in gastric cancer (GC). Here, we conduct this meta-analysis to evaluate the association between mucin expression and clinicopathological features in GC.

(SV) is a Gram-positive cocci that thrives in the acidic stomach environment and may cause gastrointestinal symptoms. A 65-year-old woman with a history of gastritis and diabetes presented with abdominal pain, vomiting, diarrhea, and weight loss. Initial esophagogastroduodenoscopy revealed pyloric stenosis with thickened prepyloric gastric folds, and endoscopic biopsy revealed SV without malignancy.

Stomach adenocarcinoma (STAD) is a common malignancy with high heterogeneity and a lack of highly precise treatment options. We downloaded the multiomics data of STAD patients in The Cancer Genome Atlas (TCGA)-STAD cohort, which included mRNA, microRNA, long non-coding RNA, somatic mutation, and DNA methylation data, from the sxdyc website. We synthesized the multiomics data of patients with STAD using 10 clustering methods, construct a consensus machine learning-driven signature (CMLS)-related prognostic models by combining 10 machine learning methods, and evaluated the prognosis models using the C-index.

Gastric cancer (GC), particularly in East Asia, is among the most prevalent cancers with high mortality rates. According to recent epidemiological data, patients with GC account for over a quarter of all cancer incidences and approximately one third of cancer-related deaths in East Asia. Liver metastasis (LM) is not only a common form of GC distant metastasis but also poses a major challenge to the prognosis and treatment of patients with advanced GC.
