Is common iliac lymph node dissection necessary in early stage cervical carcinoma?
OBJECTIVE
Nodal metastasis is one of the most important prognostic factors in early stage cervical carcinoma and has an immense impact on the subsequent management. Thus, searching for nodal metastasis by pelvic lymphadenectomy is an integral part in the surgical management of cervical carcinoma. Complete nodal clearance of lymphatic tissue up to 2 cm above the bifurcation of common iliac vessels is therefore performed as a routine in our unit. The aim of this study is to investigate the incidence and pattern of pelvic lymph node metastases in patients with early stage cervical carcinoma to determine the role of common iliac node dissection in the surgery.


METHODS
We retrospectively reviewed 174 operation and histopathology reports of patients who underwent pelvic lymphadenectomy because of stage IA2 to IIA cervical carcinoma. Lymph nodes collected below and above the bifurcation of common iliac vessels were labeled as pelvic nodes and common iliac nodes, respectively. The incidence and distribution of nodal metastases were analyzed.


RESULTS
Complete and selective pelvic lymphadenectomy was performed in 163 and 11 patients, respectively. Nodal metastasis was documented in 35 (20.1%) patients. Pelvic and common iliac nodes were involved in 34 and 8 cases, respectively. All except one patient with common iliac node metastases were also found to have pelvic node metastasis.


CONCLUSIONS
In early stage cervical carcinoma, isolated common iliac lymph node metastasis is rare, especially in cases without associated high risk factors. Less extensive pelvic lymphadenectomy may be considered in these patients in order to reduce operation morbidity and time.
