OBJECTIVE: The aim of this study was to identify the independent histopathological and clinical risk factors for pelvic lymphnodal metastasis in patients with cervical carcinoma treated with radical hysterectomy and pelvic lymphadenectomy. .METHODS: From Jan 2012 to Dec 2017, patients with stage Ib–IIa cervical cancer who underwent upfront surgery were retrospectively studied. The relationship between pelvic lymph node metastasis and age, menopausal status , histological subtype, clinical stage, tumor size, grade of differentiation, depth of stromal invasion & lympho vascular space invasion were evaluated by univariate and multivariate analyses. RESULTS: Totally 603 lymph nodes were dissected in 70 patients, with an average of 8 lymph nodes in each patient. 61.4% (43/70) were belongs to age group 50 years or more.45(64.3%) patients attained menopause.63(90%) patients had squamous cell carcinoma. Grade 1 tumors were 51.4%(36/70).stage 1B1 tumors 75.7%(53/70). Laparoscopic surgery was done in 25(35.7%)patients.15.7% of the patients (11/70) had metastasized pelvic lymph nodes. Univariate analysis indicated that tumor size (P = 0.009) and stromal invasion (P = 0.049) were significantly related to pelvic lymph node metastasis. Multivariate logistic regression analysis showed that tumor size alone ( p=0.038, 95%CI 1.064–22.248) was significantly related to pelvic lymph node metastasis in patients with early–stage squamous cell carcinoma of the uterine cervix. CONCLUSION: In early–stage cervical cancer, tumor size and stromal invasions are risk factors of pelvic lymph node metastasis.
