MALAT1 and neoplasm: We also thought our review has several limitations: (1) it is still necessary to conduct larger-size and better design studies to confirm our results; (2) the major limitation of this meta-analysis was that patients included in our study were all Asians; because of this, our finding may just represent patients from Asia; (3) literature reported tumor category is limited, so that we cannot actually confirm the MALAT-1 overexpression influence lymph node metastasis in whole human tumors; (4) a unified criterion for the division of MALAT-1 expression groups is important for this research.
