In 225 cases of stage I non-small cell lung cancer (NSCLC), it was found in 70 cases, metastasis correlates with MALAT1 over-expression, in a course and tissue specific manner, suggesting that MALAT1 expression can serve as a potential marker of survival in stage 1 NSCLC patients [11]. The gene discussed is MALAT1; the disease is non-small cell lung carcinoma.
