ABSTRACT

Objective To evaluated the risk factors of urethral recurrence ( UR) following radical cystectomy ( RC) in patients with bladder urothelial carcinoma.Methods The clinical data of 350 male patients who underwent RC between January 2005 and January 2013 were retrospectively analyzed.The mean age was 63 years (rang 46-76) years.176 cases had the history of non-muscle-invasive bladder cancer.15 cases were were found the tumor invasion into the prostatic urethral.The way of urinary diversion after RC included 172 cases were orthotopic neobladder, 90 cases were cutaneous diversion and 88 cases were ileal couduitin.331 cases underwent preoperation intravesical instillation.36 cases underwent systemic chemotherapy after operation.148 cases were found the multiple tumor lesions, which was more than 2 sites. The pathological stage was more than T2 satge in 189 cases.And 177 cases were diagnosed as high-grade urothelial carcinoma.Multivariate Cox regression analyses were used to evaluate the risk factors associated with the UR.Results There were 350 cases in this study, UR was observed in 28 cases ( 8%).On multivariate Cox regression analyses, previous history of NMIBC (HR=15.205,95%CI 3.718-62.180,P<0.001), prostate urethral involvement(HR=5.233,95%CI 1.106-24.754,P=0.037) and Non-orthotopic neobladder(HR=6.656,95%CI 1.840-24.077,P=0.004)which the operation of cutaneous diversion and ileal couduit , were independent risk factors of UR following RC.Intravesical instillation before operation ( HR =0.470, 95%CI 0.010-0.217, P <0.001 ) was the protective factor of the UR.Conclusions Previous history of NMIBC, prostatic urethral involvement and Non-orthotopic neobladder were independent risk factors of UR.Intravesical instillation before operation was protective factor of UR.Urethrectomy for patients with high risk factors and intravesical instillation before operation were important.

ABSTRACT

OBJECTIVE To investigate the diagnostic value of 131I-SPECT/CT fusion images in detecting the metastases of differentiated thyroid carcinoma(DTC)in the regions of the head,neck and superior mediastinum.METHODS 131I-SPECT/CT fusion images was preformed for 30 patients with DTC,and the results of image were compared with the pathology after surgery.RESULTS There were 110 cases positive findings in 115 metastatic lesions with 131I-SPECT/CT fusion images examination(95.65%).5 cases of the metastatic lesions showed negative in 131I-SPECT/CT(4.35%).There was no false positive case.CONCLUSION 131I-SPECT/CT fusion images can detect and locate the metastasis and exclude the false positive results accurately.It is a good method to detect the cervical and superior mediastinal metastatic lesion in differentiated thyroid carcinoma.
