Gemcitabine or 5-fluorouracil (5-FU) based treatments can be selected for pancreatic cancer....Analysis of both CDA and hENT1 was possible with 277 patients...individuals with low CDA mRNA and low hENT1 protein do better with 5-FU: median survival 29.3 (95% CI = 21.9–41.9) months compared to survival of 18.3 (95% CI = 13.9–28.3) months with gemcitabine (Table 3).
