In database test, significant correlations between high TIM-3 mRNA expression and poor overall survival for patients with non-small cell lung cancer and gastric cancer were observed (HR = 1.46, 95% CI = 1.23-1.72, <i>P</i> < 0.001; HR = 1.41, 95% CI = 1.12-1.77, <i>P</i> = 0.0038). Here, HAVCR2 is linked to non-small cell lung carcinoma.
