NCAM1 and gastrointestinal stromal tumor: Low expression of TIM-3 (Figure 2(a), P = 0.0161), CD8 (Figure S2(a), P = 0.0050), and CD56 (Figure S2(b), P = 0.0480) were significantly associated with shorter time to GIST recurrence, while Gal-9 (Figure 2(b), P = 0.2140) was not associated with GIST recurrence.
