Efficacy of Intraoperative One-step Nucleic Acid Amplification Assay for Detection of Breast Cancer Metastases in Sentinel Lymph Node
Keywords:
Breast cancer, nucleic acid amplification assay, sentinel nodeAbstract
Background: Accurate intraoperative diagnosis of sentinel lymph node (SLN) metastases enables the selectionof patients for axillary lymph node dissections during the same operation, reducing the need for a second operation.
To find out whether the one-step nucleic acid amplification (OSNA) assay (Sysmex®) has potential for intraoperative
alternative for SLN evaluation, we evaluated the efficacy of OSNA in comparison with frozen section and permanent
histological findings. Turn-around time of intraoperative OSNA assay was also considered.
Materials and Methods: In total, 111 SLN samples from 62 patients with early stage breast cancers were analyzed.
Each SLN was cut into 2-mm sections. Alternate sections were subjected to OSNA assay and histopathological
evaluation. Binomial distribution analysis with 95% confidence interval (95%CI) was used for all diagnostic value
analysis.
Results: The sensitivity and specificity of the OSNA compared with permanent section before discordant case
analyses was 84.6% (95%CI, 57.8%-95.7%) and 91.8% (95%CI, 84.7%-95.8%) respectively. Sensitivity and specificity
after discordant case analysis were 85.7% (95% CI, 60.0%-96.0%), 92.8% (95% CI, 85.8%-96.5%) and the accuracy was
91.9% (95% CI, 85.3%-95.7%). Turn-around time for OSNA assay was approximately 40 minutes.
Conclusions: The OSNA assay was proven to have high accuracy and reliability for evaluation of lymph node
metastases in breast cancer patients with acceptable processing time. The assay may be used as an alternate method
of frozen section especially in centers lacking of experienced pathologists.
