Article Synopsis
  • Epidermal growth factor receptor (EGFR) is often overexpressed in esophageal squamous cell carcinoma (ESCC), but traditional anti-EGFR treatments have not significantly improved patient survival.
  • A phase II trial tested the drug afatinib on 41 metastatic ESCC patients who had previously been treated, showing a 39% objective response rate and a median overall survival of 7.8 months with manageable side effects.
  • Additionally, the study found that the protein NTRK2 could predict resistance to afatinib, suggesting that targeting NTRK2 might improve treatment effectiveness for patients with EGFR overexpression.

Background: Immune checkpoint inhibitors (ICIs) have significantly improved patient survival in multiple cancers. However, therapy response in esophageal cancer is limited to subgroups of patients and clinically useful predictive biomarkers are lacking.

Methods: We collected a series of plasma samples from 91 patients with esophageal cancer before and after ICI treatment.

Methods: This was a single-arm historical cohort study of ESCC patients with synchronous or heterochronous LM between December 2014 and July 2021 at the Department of Gastrointestinal Oncology. The patients were treated with HAIC for LM, and regular image assessments were performed according to the judgment of the interventional physician. Liver progression-free survival (PFS), liver objective response rate (ORR), liver disease control rate (DCR), overall survival (OS), adverse events (AEs), treatment information, and basic characteristics were observed retrospectively.

Without treatment, familial adenomatous polyposis (FAP) patients will inevitably develop colorectal cancer (CRC) during lifetime. Yet, surgical trauma is a high risk of desmoid tumor (DT), one of the main causes of death in FAP patients. So far, the timing for colectomy is primarily based on the clinician's experience and the patient's preference; most patients undergo surgery at mid-20's.

Recently, an increasing number of studies have focused on the extragastrointestinal effects of Helicobacter pylori (H. pylori), including metabolic syndrome, fatty liver, and rheumatic and skin diseases. Nonalcoholic fatty liver disease (NAFLD) is a common chronic disease worldwide that conveys a heavy economic burden on patients and society.

Background: Recently, an increasing number of studies have focused on the extra-gastrointestinal effects of Helicobacter pylori (H. pylori), including metabolic syndrome, fatty liver, and rheumatic and skin diseases. Osteoporosis is an asymptomatic disease that can eventually lead to fractures and has a significant impact on the quality of life of elderly individuals.

The aim of the present study was to investigate the correlation between vascular characteristics under narrow band imaging endoscopy (NBI) and the expression of angiogenic factors of colorectal carcinoma and adenoma, and to evaluate the feasibility and validity of NBI in vivo visualizing angiogenesis. Patients with colorectal polyps, which were pathologically confirmed as early carcinoma, adenoma and hyperplastic polyp, were recruited and examined by NBI. The endoscopic vascular pattern was classified by Showa classification.
