Radical hysterectomy for FIGO stage I-IIB adenocarcinoma of the uterine cervix

A retrospective analysis was carried out to identify risk factors for survival and relapse in patients with FIGO stage I-IIB cervical adenocarcinoma (AC), who underwent radical hysterectomy, and to compare outcome and spread pattern with those of squamous cell carcinoma (SCC). One hundred and twenty-three FIGO stage I-IIB patients with AC and 455 patients with SCC, who all underwent primary radical hysterectomy, were reviewed. Among the patients with AC, Cox model identified tumour size (95% CI: 1.35-30.71) and node metastasis (95% CI: 5.09-53.44) as independent prognostic factors for survival, and infiltration to vagina (95% CI: 1.15-5.76) and node metastasis (95% CI: 6.39-58.87) as independent prognostic factors for relapse. No significant difference was found in survival or relapse between the AC and SCC groups, after adjusting for other clinicopathological characteristics using Cox model. No significant difference was found in the positive rates of lymph nodes or location of initial failure sites between the two groups, but ovarian metastatic rate was significantly higher in patients with pathologicstage IIB AC (P = 0.02). Positive node is a common independent prognostic factor for survival and relapse of patients with AC. FIGO stage I-IIB patients with AC or SCC, who underwent radical hysterectomy, have similar prognosis and spread pattern, but different ovarian metastasis rates.
