简要总结
One-step Nucleic Acid Amplification assay (the OSNA assay) (Sysmex, Kobe, Japan) was an objective molecular technique that combines node tissue homogenization and subsequent reverse-transcription loop-mediated isothermal amplification of CK-19 mRNA in a single quick step. In the study, the performance of the OSNA assay was compared with the present standard histological evaluation, and a comparative analysis of OSNA assay with Touch Imprint Cytology (TIC) was also been made.
详细描述
Patients:
More than 1000 consecutive breast cancer patients scheduled for Sentinel Lymph Node Biopsy (SLNB) were enrolled in the study. The study was approved by the ethics committee of each center and each patient provided informed consent. The patients who had undergone previous ipsilateral axillary surgery were excluded from this study.
Sampling method:
Sentinel Lymph Node (SLN) was defatted after SLNB. If the node weighed less than 100mg, the node was only assessed by histology postoperatively. If the node weighed more than 100mg, the node was sliced to equal blocks according to the length of short axis: If the length was less than 4mm, the node was sliced into two blocks along the long axis (a, b). Intraoperatively, the block a and b were tested by TIC, and the block a was prepared for OSNA. Postoperatively, the block b was assessed by histology. If the length was more than 4mm, the node was sliced into four blocks (a, b, c, d). Intraoperatively, all blocks (a, b, c, d) were tested by TIC, and the block a and c were prepared for OSNA. Postoperatively, the block b and d were subjected to histology. ALND was only performed if the TIC results were positive.
