Hereditary gastric cancer:Three rules to reduce missed diagnoses

Gastric cancer remains one of the most lethal cancers.The incidence and mortality rates are quite similar.The main reason for the high mortality is diagnosis at advanced stages of disease,when treatment options are poor.One of the supposed strategies to overcome late-stage diagnosis is identifying people at high risk with the aim of establishing rigorous clinical control,including routine endoscopy and biopsies.Hereditary gastric cancer(HGC)syndromes,though representing a sizeable group to monitor for prevention or,at least,for early diagnosis,are apparently extremely rare.The low rate of HGC diagnosis might be related to the low rates of suspicion,insufficient familiarity about clinical diagnosis criteria,and the supposed conditional necessity of a molecular diagnosis.In this review,we will discuss simple measures to increase HGC diagnosis by applying three rules that might provide an opportunity for precision care to benefit the families affected by this disease.
