A quality process study of lymph node evaluation in endometrial cancer

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Cancer Staging

Background:

• Accurate lymph node assessment is crucial for precise staging of uterine cancer.
• Variability in lymph node counts can arise from different personnel involved in dissection and analysis.
• Standardized surgical protocols aim to minimize inter-observer variability in cancer staging procedures.

Purpose of the Study:

• To compare lymph node counts reported by surgeons, histology prosectors, and pathologists.
• To evaluate consistency in lymph node dissection and reporting within a standardized national protocol for uterine cancer.
• To identify potential discrepancies in nodal counts across different roles in the patient management pathway.

Main Methods:

• Retrospective review of uterine cancer patients (n=72) undergoing standardized staging.
• Inclusion of hysterectomy, bilateral salpingo-oophorectomy, and pelvic/para-aortic lymphadenectomy.
• Analysis of lymph node counts by region, surgeon, prosector, and pathologist.

Main Results:

• A total of 2397 lymph nodes were dissected, averaging 33 nodes per patient.
• No significant differences were observed in mean lymph node counts among surgeons (P=0.66), prosectors (P=0.091), or pathologists (P=0.079).
• The standardized protocol facilitated consistent nodal dissection and reporting across disciplines.

Conclusions:

• This systematic review did not identify discrepancies in lymph node counts among healthcare professionals.
• The findings support the effectiveness of standardized protocols in achieving consistent nodal dissection.
• The methodology can inform interdepartmental reviews for optimizing nodal dissection completeness in standardized surgical settings.
