Sentinel lymph node mapping in endometrial cancer: Current evidence and practice

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Clinical Staging

Background:

• Endometrial cancer staging traditionally involves comprehensive lymphadenectomy.
• Complete pelvic and para-aortic lymphadenectomy (LND) is the established method for assessing nodal metastases.
• Minimally invasive staging techniques are increasingly explored for gynecologic malignancies.

Purpose of the Study:

• To evaluate the diagnostic accuracy of sentinel lymph node biopsy (SLNB) compared to complete lymphadenectomy in early-stage endometrial cancer.
• To assess the feasibility and safety of SLNB as an alternative staging procedure.
• To analyze the impact of SLNB on surgical outcomes and patient recovery.

Main Methods:

• Prospective studies comparing SLNB with complete pelvic and para-aortic lymphadenectomy.
• Analysis of diagnostic accuracy, including sensitivity, specificity, and false-negative rates.
• Evaluation of surgical complications and patient-reported outcomes.

Main Results:

• Sentinel lymph node biopsy demonstrates comparable diagnostic accuracy to complete lymphadenectomy for detecting nodal metastases.
• SLNB is identified as an acceptable alternative, potentially reducing operative time and morbidity.
• A paradigm shift in surgical staging for early-stage endometrial cancer is supported by current evidence.

Conclusions:

• Sentinel lymph node biopsy represents a valid and accurate method for staging early-stage endometrial cancer.
• The adoption of SLNB can optimize surgical management by offering a less invasive staging option.
• This approach aligns with the trend towards precision surgery in gynecologic oncology.
