Additionally, DFS (disease-free survival) was analyzed and showed that 4 cancer types with high KDM1A were positively related to poor prognosis, including ACC (p = 4.2e − 05), LIHC (p = 0.021), KICH (p = 0.026), and LGG (p = 0.017), and low KDM1A was associated with poor DFS for KIRC (p = 0.015). Here, KDM1A is linked to cancer.
