Sentinel lymph node biopsy in cervical cancer: A meta-analysis

Area of Science:

• Oncology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Sentinel lymph node biopsy (SLNB) assesses metastasis in the first lymph node draining a primary tumor.
• The diagnostic utility of SLNB for nodal status in cervical cancer remains undetermined.

Purpose of the Study:

• To evaluate the diagnostic accuracy and value of sentinel lymph node biopsy (SLNB) in patients with cervical cancer.

Main Methods:

• A systematic literature search was conducted on PubMed.
• Data from 17 studies (1,112 patients) were analyzed using a random-effects model.
• Subgroup analyses examined the impact of different procedural techniques.

Main Results:

• The pooled sentinel lymph node (SLN) detection rate was 92.2%, sensitivity was 88.8%, and negative predictive value was 95.0%.
• Laparoscopy, combined tracers, and immunohistochemistry were associated with significantly higher SLN detection rates.

Conclusions:

• Sentinel lymph node biopsy (SLNB) demonstrates diagnostic value in cervical cancer staging.
• Optimized SLNB procedures using laparoscopy, combined tracers, and immunohistochemistry enhance detection accuracy.
• Further research is needed to establish the definitive clinical impact of SLNB in cervical cancer management.
