In 322 Japanese non-small cell lung cancer (NSCLC) cases, UHRF1 expression was associated with the histological type (higher in non-ADCs; P<0.00001), gender (higher in male; P=0.00082), smoking (higher in smokers; P=0.00004), pT factor (higher in advanced stage; P=0.00010), and pN factor (higher in cancers with metastasis in regional lymph nodes; P=0.00018). This evidence concerns the gene UHRF1 and non-small cell lung carcinoma.
