The Clinical Analysis of Lymph Node Metastasis in Stage I,II Cervix Carcinoma

Objective:To explore the features of pelvic lymph node metastasis,the related prognostic factors and the influence to outcome in stage Ⅰ,Ⅱcervical cancer patients.Methods:We retrospectively analyzed 32 cervical cancer patients with lymph node metastasis and 32 cases without lymph node metastasis,who had undertaken extensive hysterectomy and radical pelvic lymphoadenectomy.Results:The lymph node metastasis rate was 23.35%,and the most common metastasis of cervical carcinoma occurred at the obturator node(59.37%).Pelvic lymph node metastasis was associated with deep cervical stromal invasion,which was not correlated with age,histological classification,the grade of differentiation,parametrial involvement,and lymphovascular invasion.The relevant prognostic factor for cervical carcinoma was number of lymph node metastasis,and was not the depth of cervical stromal invasion,histological classification,the grade of differentiation and lymphovascular invasion.Conclusion:The stromal invasion ≥l/2 is a risk factor of pelric lymph node metastasis in cervical cancer.The prognosis of patients with ≥3 positive pelvic lymph node are quite poor,which is helpful for clinical therapy.
