The subsequent study of the data of 212 clinical cases showed that the factors that affected the prognosis in patients included tumour location (P = .029), tumour size (P = .012), Borrmann type (P = .019), STEAP1 expression (P < .001), N stage (P < .001), T stage (P < .001) and distant metastasis (P = .005) (Table 2). Here, STEAP1 is linked to neoplasm.
