PDGFRB and colorectal cancer: These results are partly in line with previous studies performed in pancreatic and colorectal cancers.[32], [33] Regarding the prognostic value of PDGFRβ, there is some disagreement between our result and those of previous two studies which remarked the association of stromal PDGFRβ expression and poor prognosis in prostatic and pancreatic cancer, respectively.[34], [35] This discrepancy may be attributable to different cancer types or organs.
