FAM3B promotes progression of oesophageal carcinoma via regulating the AKT-MDM2-p53 signalling axis and the epithelial-mesenchymal transition.

FAM3B has been suggested to play important roles in the progression of many cancers, such as gastric, oral, colon and prostate cancer. However, little is known about the role of FAM3B in human esophageal squamous cell carcinoma (ESCC). In the present study, we found that FAM3B expression was higher in ESCC tissues than in adjacent normal tissues.

Modified Intrathoracic Esophagogastrostomy with Minimally Invasive Robot-Assisted Ivor-Lewis Esophagectomy for Cancer.

Background: Intrathoracic esophagogastrostomy plays an important role in minimally invasive Ivor-Lewis esophagectomy for cancer. Intrathoracic anastomosis with robot-assisted Ivor-Lewis esophagectomy (RAILE) includes hand-sewn and circular stapler methods, which remain technically challenging. In this study, we modified the techniques for intrathoracic anastomosis at RAILE, in order to simplify the complex procedures.

The Role and Prognostic Significance of Aortopulmonary, Anterior Mediastinal, and Tracheobronchial Lymph Nodes in Esophageal Cancer: Update of the Eighth-Edition TNM Staging System (2018).

Background: The eighth edition of TNM staging for esophageal cancer will be implemented at 2018. The stations 5, 6, and 10 lymph nodes (LNs) have been omitted from the regional lymph node map for the new TNM staging. However, the role and prognostic significance of these LN stations were not clear.

[Confirmatory factor analysis of the shortened dentine hypersensitivity experience questionnaire].

Objective: This review aims to identify the dimensional structure of the shortened dentine hypersensitivity experience questionnaire (DHEQ-15) using confirmatory factor analysis (CFA).

Methods: The Chinese language version of DHEQ-15 was applied to 210 patients with dentine hypersensitivity aged 18-70 years old. The three-dimensional construct was confirmed by CFA.

Strategies of nodal staging of the TNM system for esophageal cancer.

The 8 edition of UICC/AJCC TNM staging for esophageal cancer will start in use since 2018. The nodal staging in this version of TNM system remains unchanged from the 7 edition that based on the number of lymph nodes (LN) involved, except the limited revision of the regional LN map. In this review, N staging revision was evaluated from its initially simple definition of negative (N0) and positive (N1) LN(s) to the current positive node number based proposal.
