In contrast, our Kaplan-Meier survival analysis of TCGA data showed that patients whose gastric cancer expressed a high level of GDF15 mRNA had markedly longer median overall survival than those patients whose tumors expressed GDF15 at a low level (1747 days vs. 792 days, P = 0.05; HR = 0.71, 95% CI 0.51-1.00, P = 0.05). This evidence concerns the gene GDF15 and gastric cancer.
