SLNM and OSNA assessment of sentinel lymph nodes compared to ultrastaging

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.

Method:

After the sentinel lymph node detection (ICG, 99m Tc or Bleu Patente) and sentinel node/nodes removal is performed, the node/nodes is/are cut in 2-mm slices parallel to short axis of the node. The odd-numbered blocks will be examined by the OSNA method and the even-numbered blocks will be examined by conventional histopathological methods including immunohistochemistry.

Statistical analysis to identify differences will be performed subsequently.

Samples of the tissue homogenate will be retained and may be used for further testing.

SLNM in Endometrial Cancer Combined With OSNA

Sentinel Lymph Node Mapping in Endometrial Cancer Patients Combined With One-step Nucleic Acid Amplification (OSNA)

Number of CK 19 copies will be assessed: 250-5000 micrometastasis, more than 5000 copies macrometastasis. This result will be compared to histological ultrastaging examination.
