Impaired immune responses in patients with carcinoma of cardia or oesophagus have previously been reported. However, we do not know whether resectability correlates with specific immunological variables. Immunological assessment was performed in 35 such cancer patients including measurement of total T cells (CD3+) and T cell subsets (CD4+ and CD8+), NK cells (CD16+) and B cells (CD19+) in blood. In vitro lymphocyte responses to phytohemagglutinin (PHA) separated from peripheral blood were quantitated. The numbers in peripheral blood of both total T cells (CD3+) and B lymphocytes (CD19+) were significantly lower in the inoperable patients compared to resected patients (P < 0.01). The number of NK cells (CD16+) was, however, not significantly lower in the inoperable patients compared to the patients operated for cure. Lymphocyte responses to PHA in vitro were similar in resectable and non-resectable patients, but significantly lower in inoperable patients compared to the controls (P < 0.01). In conclusion, resectability in carcinoma of cardia or oesophagus is associated with changes in both T (CD3+) and B (CD19+) cell subsets.

This study enrolled 10 patients diagnosed with premalignant lesions and early-stage gastric cardia adenocarcinoma (GCA), confirmed through endoscopic examination. These patients were subjected to next-generation sequencing (NGS) using a customized 1123-gene panel to identify genetic alterations and signaling pathways. The results were compared to stage IIB to IV GCA samples from the cancer genome atlas (TCGA) and a cohort of Hong Kong patients.

Associations of adiposity with risks of oesophageal squamous cell carcinoma (ESCC) and non-cardia stomach cancer, both prevalent in China, are still inconclusive. While adiposity is an established risk factor for colorectal cancer, the relevance of fat-free mass and early-adulthood adiposity remains to be explored. The prospective China Kadoorie Biobank study included 0.

The term cholangiocarcinoma (CCA) includes a group of malignant tumors that develop in the efferent bile ducts and are characterized by a high degree of heterogeneity. These differences between intrahepatic, perihilar and distal CCAs run through all aspects of the disease including the etiology, pathogenesis, symptoms, diagnostics and treatment. This review article presents the current developments in this field of diseases.

Esophageal cancer, particularly squamous cell carcinoma, poses significant diagnostic challenges due to its aggressive nature and similarity to metaplastic tissue. Accurate diagnosis often requires multiple biopsies and vigilant surveillance, especially in high-risk individuals with conditions such as gastroesophageal reflux disease (GERD) and a history of smoking. We present a 66-year-old female patient with a history of severe GERD and smoking, who underwent routine endoscopy revealing a gastric cardia nodule.
