RESUMEN
Objective:To explore the value of tumor diameter to preoperative carcinoembryonic antigen (CEA) ratio (TCR) in predicting prognosis of patients with non-metastatic colorectal cancer.Methods:The clinical data of 144 patients with colorectal cancer in Hainan Hospital of PLA General Hospital between July 2012 and December 2017 were retrospectively analyzed. Patients were divided into the low TCR group and the high TCR group according to the optimal value of TCR in predicting the disease-free survival (DFS) determined by the receiver operating characteristic curve (ROC). The clinicopathological features of both groups were analyzed, and the influencing factors of DFS were also analyzed by using Cox proportional hazard model.Results:ROC analysis showed that TCR had a certain value in predicting DFS, and area under the curve (AUC) was 0.614 (95% CI 0.507-0.722); when the value of TCR was set at 0.690, the sensitivity and specificity of predicting the 3-year DFS rate was 46.3% and 70.9%, respectively. According to 0.690 of TCR, there were 50 cases in the low TCR (< 0.690) group and 94 cases in the high TCR (≥0.690) group. There were no statistically significant differences in the high and low TCR between the two groups for patients stratified by gender, age, tumor location, differentiation degree, invasive depth, lymph node metastasis, TNM stage (all P > 0.05). Univariate analysis showed that TCR, preoperative CEA level and TNM stage played a role in predicting DFS of patients (all P < 0.05), while Cox multivariate analysis indicated that TCR < 0.690 ( HR = 2.369, 95% CI 1.279-4.388, P = 0.006) and Ⅲ stage in TNM stage ( HR = 2.214, 95% CI 1.346-3.640, P = 0.002) were the independent risk factors of influencing DFS (all P < 0.01). The 3-year DFS rate of patients in the low TCR group was lower than that of those in the high TCR group (62.0% vs. 83.0%, P = 0.007). Conclusion:TCR could have a certain value in judging the prognosis of non-metastatic colorectal cancer patients, and low TCR patients have a poorer prognosis.
RESUMEN
Objective The cyst excision is considered as priority management of the female paraurethral cyst.The purpose of this present study was to explore the feasibility and safety of the two-step excision with treatment for the female paraurethral cyst.Methods Twenty eight consecutive women with paraurethral cyst underwent paraurethral cyst removal were enrolled retrospectively in this study from October 1,2005 to August 12,2008 in Urology Department of West China Hospital.Results All cases were followedup from 6 months to 2 years,no recurrence occurred.No complications such as urethral stricture and urethralvaginal fistula were found.Conclusions The 2-step excision is the reference technique for cure of female paraurethral cyst.Urethra injury was avoided efficiently,because anatomical relationship between cyst and urethra could be clearer when the technique of 2-step excision was applied.
RESUMEN
Objective To assess the outcome of vesicoureteral reflux after augmentation cystoplasty in patients with neurogenic bladder.Methods Between January 2008 and January 2014,a total of 25 patients,with a hypocompliant bladder associated with vesicoureteral reflux confirmed by video-urodynamics preoperatively,were recruited in this study.They all had undergone bladder augmentation with a generous detubularized segment of bowel at our institution.No effort had been made to correct existing reflux.Preoperatively assessment included urinalysis,kidney function tests,ultrasonography,video-urodynamic evaluation.All patients had various degrees of vesicoureteral reflux.The status of vesicoureteral reflux and bladder function were studied by video-urodynamic.Results Mean follow-up was 2.2 years (range 0.5 to 5.5 years).The video-urodynamics manifested a significant improvement of bladder capacity,diminution of intravesical pressure and resolution of reflux after bladder augmentation.Of the 25 patients,20 (80％) no longer had reflux,3 (12％) had improvement,2 (8％) had no change.Sixteen of 18 with grades Ⅰ to Ⅲ (89％),all refluxing units with grade Ⅳ to grade Ⅴ (100％) showed complete cessation of reflux.Symptomatic urinary infection was not found after surgery.Conclusions Augmentation enterocystoplasty without ureteral reimplantation is effective and adequate for patients with high pressure and hypocompliant neurogenic bladder.Therefore,ureteral reimplantation is not necessary underwent when augmentation enterocystoplasty is recommended to patients with neurogenic bladder and vesicoureteral reflux.
