Value of sentinel node ultrastaging and pathologic techniques in tumoral detection

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Cancer Diagnostics

Background:

• Sentinel lymph node (SLN) assessment is a key surgical option for early-stage vulvar, endometrial, cervical, and ovarian cancers.
• Ultrastaging of lymph nodes is mandatory for accurate staging but lacks universally accepted pathology protocols.

Purpose of the Study:

• To review current evidence on SLN evaluation in gynecologic neoplasms.
• To discuss controversial aspects like frozen section and one-step nucleic acid amplification.

Main Methods:

• Review of existing literature on SLN evaluation in gynecologic cancers.
• Analysis of diagnostic accuracy and ultrastaging protocols.

Main Results:

• High diagnostic accuracy of SLN detection algorithms for gynecologic neoplasms.
• Heterogeneity in studies and lack of clear guideline recommendations hinder protocol selection.
• Optimal ultrastaging requirements for maximum accuracy and minimal cost remain undetermined.

Conclusions:

• SLN evaluation is integral to managing early-stage gynecologic neoplasms.
• A significant gap exists in universally accepted ultrastaging pathology protocols.
• Collaborative efforts between gynecologic oncology and pathology are essential to advance surgical management.
