ABSTRACT
The incidence and mortality of digestive system tumors are high,and the trend is increasing year by year,and the early onset is hidden,difficult to detect,and seriously threaten human health.In recent years,it has been found that long noncoding RNA(lncRNA),as a new class of non-coding RNA,plays an important role in the occurrence and development of tumors,influencing the occurrence and development of tumors by regulating the malignant biological characteristics of tumor cells such as proliferation,invasion and metastasis.Further study on the role of lncRNA in digestive system tumors can further discover its diagnosis and treatment methods,and provide new ideas for reducing the incidence and mortality of digestive system tumors.This article reviewed the progress of research in lncRNA in digestive system tumors.
