NT5E and rectal cancer: CD73 expression in rectal cancer only samples;CD73 expression is increased in both tumor and stromal cells;High CD73 expression in cancer cells associates with poor patient prognosis;High CD73 expression in stromal cells associates with favorable characteristics (early T and tumor-node-metastasis (TMN) stages) and overall survival;Patients with high CD73 expression in both the cancer cells and stromal cells have similar good outcomes. No CD73 expression in both cell compartments is also favorable
