qRT–PCR assay. The expression levels of five microRNAs (miR-34c-5P, miR-375, miR-184, miR-34c-3p, and miR-34b-5p) were significantly lower in the grade 1–2 EC FFPE primary tumor samples with positive LN compared with those with negative LN. Mann–Whitney test, *P<0.05; **P<0.01; ***P<0.001; mean±s.e.m. EC, endometrial cancer; FFPE, formalin-fixed paraffin-embedded; LN, lymph node.
