Which is the appropriate surgical procedure for Stage I endometrial carcinoma

To study the appropriate surgical procedure for Stage I endometrial carcinoma (EC), the clinical and pathological features and prognosis factors, as well as types were analyzed retrospectively.This is a retrospective study of 277 patients with early-stage EC in clinical Stages I that received surgery between January 2000 and March 2008. The appropriate surgical procedures were divided into three types (procedure I-III: hysterectomy with or without ovary preservation, subradical hysterectomy plus pelvic lymph node biopsy, and radical hysterectomy pelvic plus lymphadenectomy) according to the clinical stage.Tumor invasion of the cervix and deep muscularis as well as the parametrium, EC Stage Ib, grade 3 and ascites had carcinoma cells, were high-risk factors of EC metastasis to the retroperitoneum (p < 0.05). The ovarian preservation of EC Stage Ia had no effect on overall survival. The three types of procedure for the EC Stage Ia were not correlated significantly to the three-year and five-year survival rates. The three-year and five-year survival rates of three surgical procedures for the EC Stage Ib were significantly correlated. The survival rates of surgical procedures II and III were significantly higher than that of procedure I (P < 0.05).Subradical hysterectomy plus pelvic lymph node biopsy was recommended for EC Stage 1b with high-risk factors. There was no evidence of benefit in terms of overall or recurrence-free survival for radical hysterectomy plus pelvic lymphadenectomy in women with Stage I EC.
