Consistent with the results from breast [34], [37], [42], lung [38], pancreatic [40], bladder [41] and prostate [43] cancer patients, we found that patients with high ALDH1 had shorter disease free and overall survival times compared to those with low ALDH1 (p = 0.0036 and p = 0.023, respectively, Figure 2D). This evidence concerns the gene ALDH1A1 and cancer.
