Lymph node assessment in cervical cancer: current approaches.

Area of Science:

• Gynecologic Oncology
• Medical Imaging
• Surgical Pathology

Background:

• Cervical cancer (CC) is a significant global health issue, with many patients diagnosed at advanced stages.
• Lymph node (LN) status critically influences treatment decisions and patient outcomes in CC.
• Traditional staging relied on clinical findings; modern staging incorporates imaging and pathology.

Purpose of the Study:

• To review and compare the advantages and limitations of various lymph node assessment modalities in cervical cancer.
• To discuss the evolving landscape of LN status evaluation in CC management.
• To provide insights into the controversial topic of optimal LN assessment strategies.

Main Methods:

• Review of current surgical techniques including full pelvic lymphadenectomy and sentinel lymph node (SLN) biopsy, noting indocyanine green (ICG) as a preferred dye.
• Evaluation of imaging modalities such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET/CT) for LN assessment.
• Comparison of the diagnostic accuracy, benefits, and drawbacks of surgical versus imaging approaches.

Main Results:

• Sentinel lymph node biopsy is now a standard surgical approach for CC.
• Pelvic MRI is valuable for evaluating pelvic LNs, while PET/CT is recommended for advanced or suspicious cases.
• Each modality presents unique advantages and limitations, contributing to ongoing debate on the best strategy.

Conclusions:

• The optimal strategy for lymph node assessment in cervical cancer remains a subject of debate.
• A comprehensive understanding of both surgical and imaging techniques is essential for effective CC management.
• Future research may further refine the comparative effectiveness of these diagnostic tools.
