The associations between NDRG2 and cancer have been reported in neurologic tumors [19, 51–57], gastrointestinal tumors [9–11, 13, 14, 55, 58–75], genitourinary tumors [12, 76–82], breast cancer [21, 83–85], lung cancer [15, 86], thyroid cancer [83, 87], fibrosarcoma [88], oral squamous-cell carcinoma [89], myeloid leukemia [90] and cervical cancer (Hela cells) [25] (Table 1). This evidence concerns the gene NDRG2 and lung carcinoma.
