Regarding tumor grading, neither in low-grade (i.e., G1/2) nor in high-grade (i.e., G3/4) tissue, NT5DC2 expression deduced SMA-positivity (i.e., ≥20% SMA+ of all stromal cells [35]) (p = 0.823, and p = 0.389, respectively) or CD34-positivity (i.e., ≥1% CD34+ of all stromal cells [35]) (p = 0.173, and p = 0.508, respectively) of stromal cells. The gene discussed is SMN1; the disease is neoplasm.
