We found that no or low expression of TIM-3 (Figure 2(a), P = 0.0155), CD8 (Figure S2(a), P = 0.0047), and CD56 (Figure S2(b), P = 0.0367) were associated with poor GIST-specific survival, while expression of Gal-9 (Figure 2(b), P = 0.2140) was not associated with GIST-specific survival. The gene discussed is CD8A; the disease is gastrointestinal stromal tumor.
