Esophageal cancer (EC) is a common malignant tumor of the digestive system. Exploring the molecular biological mechanism of EC will help to clarify its carcinogenesis mechanism, find important molecular targets in the process of carcinogenesis, and provide new ideas for the diagnosis and treatment of EC. Phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is one of the signal transduction pathways most closely related to cell proliferation and apoptosis. The regulation of various downstream molecules affects the proliferation and growth of tumor cells. In this study, we determined the effect of different concentrations of afuresertib on cell viability by MTT assay and determined the effect of afuresertib on cell apoptosis by Annexin V-FITC/PI dual staining. Animal experiments verified the effects of afuresertib on VEGF, bFGF, and PI3K/Akt. Our results indicated that afuresertib is closely related to the survival, proliferation, and apoptosis of esophageal cancer cell lines. More importantly, we found that afuresertib could reduce tumor volume and mass in EC rats through in vivo experiments. In conclusion, afuresertib may exert its antitumor effect by inhibiting the expression of PI3K and Akt-related proteins in rat tumor tissues.

Inherited genetics represents an important contributor to risk of esophageal adenocarcinoma (EAC), and its precursor Barrett's esophagus (BE). Genome-wide association studies have identified ∼30 susceptibility variants for BE/EAC, yet genetic interactions remain unexamined. To address challenges in large-scale G×G scans, we combined knowledge-guided filtering and machine learning approaches, focusing on genes with (A) known/plausible links to BE/EAC pathogenesis (n=493) or (B) prior evidence of biological interactions (n=4,196).

Background And Purpose: It remains unclear whether the lymph-node ratio (LNR) is a relevant factor for the risk of recurrence following neoadjuvant chemotherapy (nCT) with docetaxel, cisplatin, and 5-fluorouracil (DCF), which is a new standard of care for locally advanced esophageal squamous cell carcinoma (ESCC) in Japan. This study aimed to evaluate the clinical utility of LNR as a risk factor for recurrence.
Materials And Methods: We retrospectively analyzed 75 patients who underwent nCT-DCF followed by curative surgery for resectable ESCC.

Background: Malignant esophageal mediastinal fistula is a severe complication that occurs in both the advanced stages of esophageal cancer and after radiotherapy for esophageal cancer. Esophageal mediastinal fistula is very susceptible to complications such as mediastinitis and mediastinal abscess, resulting in a significantly elevated mortality rate for patients. We reported a rare case of esophageal mediastinal fistula after immunotherapy for non-small cell lung cancer (NSCLC).

Background: A detrimental association between radiation-induced lymphopenia (RIL) and oncologic outcomes in esophageal cancer patients has been established. However, an optimal metric for RIL remains undefined, but is important for application of this knowledge in clinical decision-making and trial designs. The aim of this study was to find the optimal RIL metric discerning survival.
