Due to an increased early detection rate and therapeutic
advancements, the survival of gastric cancer (GC) patients
has improved in the past 3 decades worldwide. However, GC
remains the second leading cause of cancer death in China
[1], mainly because of the disappointing early detection rate
in China, early tumour recurrence, and high chemotherapy
resistance. Hence, it is essential for gastroenterologists to
identify effective biomarkers for evaluating the early detection
of GC, which may also be targets for novel therapies for
this deadly disease
