FSTL3 and cancer: Furthermore, FSTL3 was compared according to the differences between pathological manifestations (Table S3); it was strongly correlated with tumour stage (p = 0.0017), tumour size (p = 0.0001), degree of cancer invasion of lymph nodes (p < 0.0005), and metastasis (p = 0.0429) (Figure 1D).
