In contrast, the high SNA/anti-TF IgM index was associated with poor prognosis (n = 112, HR = 0.44 (0.25–0.77), P = 0.0038) (Figure 6(c)), especially in patients with intestinal tumors (Figure 6(d)) exhibiting a more pronounced association (P = 0.005; HR = −0.34 (0.16–0.72); n = 69) in both males and females: P was 0.07 and 0.026, respectively. Here, TF is linked to intestinal neoplasm.
