Esophageal cancer is a malignant tumor with a five-year survival rate of less than 20%. Early diagnosis and exploration of esophageal cancer pathogenesis are of great significance for the treatment and prognosis of esophageal cancer. Long non-coding RNA (lncRNA) plays a vital role in the occurrence and development of different types of tumors. However, the role of exosome LncRNA in esophageal squamous cell carcinoma (ESCC) is rarely reported. In this study, we detected high expression of lncRNA LINC01711 in ESCC tissues and was associated with poor prognosis. Silencing LINC01711 can inhibit the proliferation, migration, invasion, and growth of ESCC cell lines, and induce apoptosis. Linc01711 was identified as a competitive endogenous RNA that suppressed miR-326, and up-regulated the expression of fascin actin-bundling protein 1 (FSCN1). Besides, experiments showed that the administration of exosome-derived LINC01711 (LINC01711-Exo) promoted the growth of tumors in nude mice. In general, exosomal LINC01711 promoted the proliferation, migration, and invasion of esophageal cancer cells by up-regulating FSCN1 and down-regulating miR-326, thus improved the occurrence and development of ESCC.

Esophageal squamous cell carcinoma (ESCC) is a prevalent and highly lethal malignancy in Asia. Recent advancements in immune checkpoint inhibitors (ICIs) have markedly transformed the systemic therapy landscape for ESCC. Anti-PD-1-based combination with chemotherapy or with ipilimumab, an anti-CTLA-4 antibody, have been established as the new standard first-line treatments for patients with advanced ESCC.

Background: The methyltransferase gene family is known for its diverse biological functions and critical role in tumorigenesis. This study aimed to identify these family genes in common gastrointestinal (GI) cancers using comprehensive methodologies.
Methods: Gene identification involved analysis of scientific literature and insights from The Cancer Genome Atlas (TCGA) database.

Whether preoperative chemoradiotherapy (CRT) or perioperative chemotherapy is superior for localized esophageal or gastro-esophageal junction (GEJ) cancers has been a topic of long-standing debate. For years, standard of care in the United States for localized esophageal or GEJ adenocarcinoma (EAC) has been physician's choice between the 2 strategies. More recently, adjuvant immunotherapy has also been introduced into the treatment approach for those who received neoadjuvant CRT.

Introduction: The prognostic impact of human leukocyte antigen-E (HLA-E) expression and the proportion of natural killer (NK) cells in esophageal squamous cell carcinoma (ESCC) was investigated.
Methods: This study retrospectively evaluated 397 ESCC patients across two centers. The cumulative incidence of recurrence (CIR) and the incidence of tumor-related death (CID) were analyzed in various groups.
Pseudoprogression in CAR-T cell therapy for solid tumor: Case report.

We reported the pseudoprogression in an elderly patient with advanced gastric cancer after chimeric antigen receptor (CAR)-T cell therapy. The hepatic metastases enlarged 1 month after CAR-T cell infusion and then shrunk the next month as seen through computed tomography scanning. Based on a comprehensive evaluation that includes imaging, pathology, serum tumor markers, and clinical symptoms, we arrived at a diagnosis of pseudoprogression after CAR-T cell therapy, which has not been reported in previous studies.
