When analyzing correlations in patients with stage III-IV gastric cancer, we found four strong correlations: Imax spon.—CAT, Imax spon.—GPO, Imax spon.—CP, Imax induced.—SOD and eight average correlation relationships: Imax spon.—MDA, Imax spon.—SOD, Imax spon.—GST, Imax induced.—MDA, Imax induced.—CAT, Imax induced.—GST, Imax induced.—GPO, Imax induced.—CP (Table 3). The gene discussed is CP; the disease is gastric cancer.
