Summary
Common iliac lymph node metastasis is rare in early cervical cancer without high-risk factors. Less extensive pelvic lymphadenectomy may be considered to reduce surgical morbidity.
Area of Science:
- Gynecologic Oncology
- Surgical Pathology
Background:
- Nodal metastasis is a critical prognostic factor in early cervical cancer.
- Pelvic lymphadenectomy is standard for assessing nodal status and guiding treatment.
Purpose of the Study:
- To determine the incidence and pattern of pelvic lymph node metastases in early-stage cervical carcinoma.
- To evaluate the role of common iliac lymph node dissection in surgical management.
Main Methods:
- Retrospective review of 174 patient reports (Stage IA2-IIA cervical carcinoma).
- Analysis of lymph node metastasis incidence and distribution below and above the common iliac bifurcation.
Main Results:
- Nodal metastasis occurred in 20.1% of patients.
- Pelvic and common iliac nodes were involved in 34 and 8 cases, respectively.
- Isolated common iliac metastasis was rare, with most cases also involving pelvic nodes.
Conclusions:
- Isolated common iliac lymph node metastasis is uncommon in early cervical cancer, particularly without high-risk factors.
- Less extensive pelvic lymphadenectomy could be considered to decrease surgical morbidity and operative time.
