Immunotherapy for metastatic gastric cancer.

This editorial discusses the article written by Chen that was published in the latest edition of the . The current study found that programmed cell death 1 ligand 1 (PD-L1) expression is considered as one of the pan-cancer biomarkers of immune checkpoint inhibitors (ICIs) treatment response. Four molecular subtypes are widely used to guide and evaluate the prognosis and diagnosis and treatment of gastric cancer (GC) patients.

Overview of ectopic pancreas.

This editorial discusses the article written by Zheng that was published in the latest edition of the . Our primary focus is on the causes, location, diagnosis, histological classification, and therapy of ectopic pancreas. Ectopic pancreas refers to the presence of pancreatic tissue that is situated in a location outside its usual anatomical placement, and is not connected to the normal pancreas in terms of blood supply or anatomical structure.

Quantitative determination of HER2 expression by confocal microscopy assay in CTCs of breast cancer.

HER2 analysis in circulating tumor cells (CTCs) may have clinical significance for HER2-targeted therapy as HER2-positive CTCs and disseminated tumor cells can be detected in patients with HER2-negative primary tumors who currently do not have access to HER2-targeted therapy. In this study, we performed quantitative analysis by confocal microscopy assay for evaluation of HER2 expression in individual tumor cells. HER2 testing by confocal microscopy assay exhibited high concordance with results of real-time PCR, Western blot analysis and FISH analysis.

[Tumor dormancy and identification of therapeutic targets].

Tumor dormancy is characterized by long-term persistence of cancer cells that do not grow into overt lesions. It is a common phenomenon detected in cancer patients, even in some healthy individuals. Long term existence of dormant tumor cells may contribute to tumor recurrence and metastasis.
