Due to mucinous adenocarcinoma characteristically high extracellular mucin content (27)—which results in imaging features and ADC measurements that differ significantly from non-mucinous GCs—and its relatively low incidence (2.8-6.6% of cases (28)), we excluded mucinous adenocarcinoma cases from our final analysis. The gene discussed is MUC5AC; the disease is mucinous adenocarcinoma.
