When stromal ALDH1 was evaluated in lymph node metastasis, it occurred to be an independent predictor of longer disease-free (Cox Regression model, HR = 0.627, CI95% 0.454–0.865, p = 0.004, n = 79) and metastasis-free survival (Cox Regression model, HR = 0.405, CI95% 0.226–0.725, p = 0.002, n = 51) (Table 1B). This evidence concerns the gene ALDH1A1 and metastatic malignant neoplasm in the lymph nodes.
