Wang et al. showed that while SPP1 had no significant association with GC overall survival, high expression level of THBS2 in GC patients was correlated with shorter survival time [61] [60].Bioinformatics reanalysis suggested the prognostic value of COL1A1, COL1A2, and THBS2 in GC. The gene discussed is COL1A2; the disease is gastric cancer.
