In addition, we found inverse correlations between decorin expression, measured by qRT-PCR or IHC, and the residual tumor cellularity of the surgical specimens (r = −0.64, P = 0.0006; and r = −0.55, P = 0.0067, respectively), as well as with 18FDG/PET response, the primary endpoint of our clinical trial (r = −0.50, P = 0.0120; and r = −0.4380, P = 0.0207, respectively) (Supplementary Figure 1D, 1E and 1F). The gene discussed is DCN; the disease is neoplasm.
