MicroRNAs (miRNAs) act a role in regulation numerous processes crucial for oncogenesis. The aim of the study was to compare the blood serum concentrations of selected microRNAs (miRNA-21, miRNA-10b and miRNA-200c) between breast cancer patients without sentinel lymph node metastasis (Group 1) and those with metastasis (Group 2). The serum levels of miRNA-21, miRNA-10b and miRNA-200c were measured with using TaqMan PCR assays performed on a 7900HT Fast Real-Time PCR System in two groups of breast cancer patients: Group 1 – without sentinel lymph node metastasis (32 patients) and Group 2 – with sentinel lymph node metastasis (14 patients). The mean level of miRNA-200c was noticeably lower in Group 2 than in Group 1. The mean fold change of miRNA-200c level in the metastatic group (Group 2) was approximately 1.3 times lower than that in non-metastatic group (Group 1). However, this result just approached the arbitrary threshold for significance (p = 0.05). Breast cancer patients with sentinel lymph node metastasis demonstrate diminished levels of circulating miR-200c compared to non-metastatic patients.
