Furthermore, pairwise correlation analysis of these three markers shows that the high expression of CD44/CD47, CD44/c-met, CD47/c-met was correlated with patient surgical stage, chemotherapy resistance and prognosis (all p < 0.05), but did not correlate with lymph node metastasis (all p > 0.05) (Table 5). Here, CD47 is linked to metastatic malignant neoplasm in the lymph nodes.
