[Status and prospect of esophageal cancer screening].

Abstract

Esophageal cancer is one of the global public health problems, which is a serious threat to life and health. Screening is not only an important main measures to reduce the incidence and mortality of esophageal cancer, but also an effective strategy for early prevention and early treatment. There are significant differences in the screening status of esophageal adenocarcinoma and esophageal squamous cell carcinoma cancer between China and abroad. Internationally, there are several guidelines for screening and monitoring of Barrett's esophagus and esophageal adenocarcinoma, but most guidelines do not recommend screening in the general population. The primary screening by sponge ball then endoscopic diagnosis is a new focus. In China, the screening of esophageal cancer and its precancerous lesions is mainly esophageal squamous cell carcinoma, which has been relatively mature and gradually transformed from population screening to opportunistic screening. However, due to the high cost, high technical difficulty and certain invasiveness, it is difficult to popularize and be applied widely; and the canceration rate of precancerous lesions is low, so it is very important to control the cost of screening and scientific follow-up. Moreover, high-risk population should raise their awareness of cancer prevention, actively take primary prevention and the initiative to participate in screening. About medicine institutions, it is urgent to improve the awareness and capacity of early screening. The multi-disciplinary research cooperation, minimally invasive, simple and economical screening methods and multi-omics biomarkers are still explored to detect and concentrate high-risk populations, which will help to optimize screening programs of esophageal cancer and further reduce the incidence and mortality of esophageal cancer.
