RPL22L1 and metastatic malignant neoplasm in the lymph nodes: Further, we found the expression level was significantly correlated with disease stage (81.7% in stage 2–4 versus 64.5% in stage 1) invasion depth (81.9% in T2–T4 versus 64.5% in T1), and lymph node metastasis (86.6% with versus 70.3% without metastasis), suggesting that the high level of RPL22L1 in OC cells may facilitate the invasive/metastatic phenotype.
