[One-Step Nucleic Acid Amplification method - what is the future of sentinel lymph node management?]

Area of Science:

• Oncology
• Surgical Pathology
• Molecular Diagnostics

Background:

• Sentinel lymph node biopsy is crucial for cancer staging.
• Accurate and rapid assessment of sentinel lymph nodes is essential for perioperative management.
• Current methods may have limitations in speed or sensitivity.

Purpose of the Study:

• To review the current applications of the One-Step Nucleic Acid Amplification (OSNA) method.
• To evaluate OSNA's utility in perioperative sentinel lymph node management.
• To assess OSNA's potential in various oncologic surgeries.

Main Methods:

• Literature review of studies published until April 2017.
• Search conducted on the PubMed database using "OSNA" and "One-Step Nucleic Acid Amplification".
• Focus on studies utilizing cytokeratin 19 (CK19) detection in sentinel lymph nodes.

Main Results:

• OSNA, detecting CK19, is an acceptable method for perioperative sentinel lymph node management.
• The method is currently established for breast and colorectal cancer.
• Preliminary data suggests potential for thyroid, gastric, uterine, and head and neck cancers.

Conclusions:

• OSNA is a viable option for sentinel lymph node analysis in specific cancers.
• Expanded use in other malignancies requires further investigation and data.
• The method offers a promising approach to improve oncologic surgical management.
