Objective To investigate the clinicopathological features,survival,and the impact of postoperative adjuvant radiotherapy on the ovarian function in patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer.Methods One hundred and eighty-six patients who were admitted to our hospital from 2000 to 2011 were retrospectively analyzed.An equal number of patients older than 35 years of age with cervical cancer within the same period were used as stage-marched controls.The Kaplan-Meier method was used to calculate the survival rates,and the log-rank test was used for pairwise comparison and univariate prognostic analyses.The Cox proportional hazards model was used for multivariate prognostic analyses.Results The patients less than or equal to 35 years of age had a significantly higher incidence of non-squamous carcinoma but significantly lower incidence rates of deep stromal invasion and lymph-vascular space invasion (LVSI) compared with the control group (P =0.000;P =0.008;P =0.000).Though young patients had significantly higher 5-year disease-free survival (DFS) and overall survival (OS) rates than the control group (93.7％ vs.84.5％,P=0.005;96.1％ vs.89.5％,P=0.033),age was not an independent prognostic factor (P =0.202;P =0.950).Among patients less than or equal to 35 years of age,lymph node metastasis and LVSI were independent prognostic factors for DFS (P =0.000;P =0.000),while LVSI and initial tumor size were independent prognostic factors for OS (P =0.000;P =0.000).There was no significant difference in the incidence of normal ovarian function between young patients treated with and without adjuvant radiotherapy after ovarian transposition (63％ vs.73％,P =0.422).Conclusions Patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer have a better prognosis than the control group.However,age is not an independent prognostic factor.Postoperative adjuvant radiotherapy will not impair the function of transposed ovaries.

Objective To analyze effect of balloon embolization therapy for traumatic carotid cavernous fistula (TCCF),so as to provide references for treatment of this disease.Methods A total of 21 patients with TCCF managed with balloon embolization from April 2006 to March 2012 were collected in the study.There were 17 males aged (32.3 ±5.4) years and 4 females aged (40.6 ±5.8)years.Perioperative clinical presentations and imageologic changes were observed as well as operative outcome was evaluated.Results After 3 months of follow-up,20 patients experienced successful detachable balloon embolization,but the other one patient had to have stent angioplasty due to the failure of the procedure.All patients had some improvements on clinical presentations after operation (P ＜ 0.05).Imageologic examination revealed that all patients had complete occlusion of TCCF following operation.In follow-up,one patient had a relapse,with total curative ratio of 95％.Conclusions Detachable balloon embolization is effective in treatment of TCCF.Presently,the technique is an optimal method for such kind of disease and is worthy of wide clinical use.
