Paraaortic lymph node evaluation in stage I endometrial carcinoma

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Cancer Staging

Background:

• Endometrial adenocarcinoma is the most common gynecologic malignancy.
• Accurate staging is crucial for treatment planning and prognosis in early-stage disease.
• The role of paraaortic lymph node assessment in FIGO stage I endometrial cancer requires further clarification.

Purpose of the Study:

• To evaluate the incidence and predictors of paraaortic lymph node metastasis in FIGO stage I endometrial adenocarcinoma.
• To determine the clinical significance of paraaortic lymph node involvement in early-stage endometrial cancer.

Main Methods:

• Retrospective analysis of 41 women with FIGO stage I endometrial adenocarcinoma.
• Surgical staging included paraaortic lymphadenectomy and/or lymph node biopsy.
• Correlation of paraaortic lymph node metastasis with tumor grade and myometrial invasion depth.

Main Results:

• Para-aortic lymph node metastasis was found in 14.6% of patients.
• Metastasis rates increased significantly with higher tumor grade (37.5% for grade 3) and deep myometrial invasion (45.5%).
• Grade 3 tumors or deep myometrial invasion were present in 83.3% of patients with paraaortic node metastasis.

Conclusions:

• Paraaortic lymph node metastasis is a significant concern in select cases of FIGO stage I endometrial adenocarcinoma.
• Tumor grade 3 and deep myometrial invasion are strong predictors of paraaortic lymph node involvement.
• Surgical staging with paraaortic lymphadenectomy or biopsy is recommended for early endometrial cancer with high-risk features.
