ERBB2 and gastric cancer: In recent years, radiomics has proven to be effective in the characterization of GC pathology, including depth of tumor infiltration assessment [19], determination of the Lauren classification subtype [20], evaluation of the tumor immune microenvironment [21], prediction of lymph node metastasis [22], lymphovascular invasion [23], and HER2 status [24], suggesting that radiomics may hold potential for evaluating the pathologic agreement between the two types of specimens in GC.
