SLC29A1 and neoplasm: A positive association between mutant p53 cells and hENT-1 expression was observed in iCCA tissue samples; furthermore, patients receiving adjuvant gemcitabine and expressing mutant p53 cells > 4% in tumor tissue had a longer disease-free survival (DFS) than patients expressing mutant p53 cells ≤ 4% (median 18.5 vs. 6 months, p = 0.0229).
