In multivariable analysis, unfavorable tumor architecture (HR = 3.20, 95% CI = 1.32–7.76; p = 0.010) and high tumor cell PDGFRB expression (HR = 1.02, 95% CI = 1.00–1.03; p = 0.006) were independently associated with shorter survival (see Table 2 in supplementary material, File S3). The gene discussed is PDGFRB; the disease is neoplasm.
