Summary
Brief summary (as posted)
The aim of the study is to compare one-step nucleic acid amplification method (OSNA) with histological ultrastaging examination in the sentinel lymph node assessment in patients with endometrial cancer. The molecular biologic method OSNA is a modern way of metastatic spread detection in lymphatic nodes using quantitative reverse transcription polymerase chain reaction. Cytokeratin 19 (CK 19) was selected based on previous studies as the optimal mRNA marker (detected by OSNA). The intraoperative identification and rapid assessment of sentinel lymph nodes by OSNA could help to improve the standards of care in endometrial cancer patients.
