RESUMO
【Objective】 To explore the diagnosis, treatment and prognosis of renal cell carcinoma (RCC) patients with Stauffer syndrome. 【Methods】 The clinicopathological and follow-up data of 17 RCC patients with Stauffer syndrome who underwent operation during Sep.2014 and Aug.2019 were retrospectively analyzed. The survival was analyzed with Kaplan-Meier curve and log-rank, and related factors affecting the prognosis were determined with univariate and multivariate Cox regression model. 【Results】 The pathological results included clear cell RCC in 14 cases, papillary RCC in 2 cases, and poorly differentiated tissue in 1 case. The liver function recovered within 3 months after operation in 5 cases, within 6 months in 3 cases, within 1 year in 4 cases, and did not recover in 3 cases. During the follow up of 6 to 72 (average 54.1) months, the 1-, 3-, and 5-year survival rates were 88.2% (15/17), 76.5% (13/17) and 52.9% (9/17), respectively. Survival analysis showed that the cancer-specific survival (CSS) of RCC patients with Stauffer syndrome was low, and tumor size, AJCC stage, lymph node metastasis and Stauffer syndrome were predictors of poor prognosis. 【Conclusion】 The prognosis of RCC patients with Stauffer syndrome is poor, and early surgical intervention should be conducted. The liver function of most patients can return to normal gradually after surgery. Continuous examination of liver function has significant meaning for tumor recurrence, metastasis and prognosis.

RESUMO
To systematically evaluate the expression of lymphovascular invasion (LVI) in predicting the clinical prognosis of patients after radical cystectomy.Methods The relevant search strategy,including and excluding criteria for the relevant literature were developed by two independent researchers.The study of tumor prognosis in the patients with LVI following radical cystectomy cancer were searched by computerized PubMed,EMBASE,Web of Science,Cochrane library,China National Knowledge Infrastructure (CNKI),Wanfang and VIP citation database.The search period was setted from the beginning of establishment of library until May 2017,and the search language was English and Chinese.The methodological quality of the included studies was assessed by the NOS.Besides,the relationship between LVI and the clinical outcome in patients following radical cystectomy was calculated by RevMan 5.3 and Stata 12.0 software.Results A total of 18 related clinical studies were included,published from 2008 to 2017.There were 12 354 patients with bladder cancer,of which 4 272 cases of LVI,with a proportion rate 34.6％.The results showed that the patients with LVI in pathological sections had a lower overall survival rate (HR =1.26,95％ CI 1.16-1.38,P ＜0.001),recurrence-free survival (HR =1.27,95％ CI 1.06-1.52,P ＜0.001),cancer-specific survival rate (HR =1.30,95％CI 1.18-1.42,P ＜0.001).Egger's publication bias analysis showed no significant publication bias in terms of overall survival(P =0.636),recurrence-free survival (P =0.077),and cancer-specific survival (P =0.342).Conclusions LVI had a significant poor outcome in patients with radical resection of bladder cancer.It can be used as an independent risk factor to evaluate the postoperative prognosis of those patients,but more randomized controlled studies are still needed to make a further conformity in our completion.
RESUMO
Objective To systematically compare the efficacy of three-dimensional conformal radiotherapy (3D-CRT) versus intensity-modulated radiotherapy (IMRT) in the treatment of prostate cancer (PCa).Methods Clinical comparative studies of IMRT and 3D-CRT in the treatment of PCa were collected from PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang Data after two independent researchers developed the strategy and inclusion and exclusion criteria for the literature search.Articles published up to February 2017 were searched for, and the languages of publications were restricted to English and Chinese.Clinical meta-analysis of the data from the relevant studies was performed using the RevMan5.3 software.Results A total of 15 relevant retrospective cohort studies were collected from the databases in strict accordance to the search strategy and inclusion and excluding criteria.There were 4608 PCa patients, including 2229 in the IMRT group and 2379 in the 3D-CRT group.IMRT and 3D-CRT had similar adverse effects in terms of early-stage (odds ratio[OR]=0.77, 95% confidence interval[CI]:0.43-1.40, P=0.390) and late-stage (OR=0.75, 95%CI:0.55-1.04, P=0.080) urinary tract injury.However, IMRT led to reduced early-stage (OR=0.47, 95%CI:0.27-0.82, P=0.008) and late-stage (OR=0.52, 95%CI:0.35-0.78, P=0.001) intestinal injury compared with 3D-CRT.Meanwhile, the biochemical recurrence-free survival rate was also significantly higher in the IMRT group than in the 3D-CRT group (OR=1.87, 95%CI:1.51-2.32, P=0.000).Conclusions IMRT is more protective against intestinal injury with a higher biochemical recurrence-free survival rate compared with 3D-CRT during the treatment of PCa.
RESUMO
Objective@#To explore the clinical effects of retroperitoneal laparoscopic ureterolithotomy (RPLU) and flexible-ureteroscopic holmium laser lithotripsy (f-UHLL) for complicated upper ureteral calculi.@*Methods@#A total of 45 cases of complicated upper ureteral calculi between March 2014 and January 2016 in Department of Urology, Affiliated Jiangyin Hospital of Southeast University Medical College were retrospectively analyzed, there were 32 males and 13 females, ranging from 27 to 45 years with an average age of (34.1±9.5) years. Of the 45 patients, 28 had ureteral distortion and 17 had concurrent ureteral stones in the lower or middle ipsilateral ureter. In those patients, 20 cases underwent f-UHLL, and 25 cases received RPLU. The stone size, operation time, hospital stay, stone clearance rates and postoperative fever rates between the two groups were compared with t test and χ2test.@*Results@#The operation was successfully performed in all patients, no complications with leakage of urine or ureteral perforation occurred, and no significant difference in renal function between the two methods were founded in postoperative period. There was no significant difference in operation time((78.4±8.5) minuetes vs.(73.3±11.3) minuetes, t=0.61, P=0.67), time of double J tube removed ((33.8±3.4)days vs. (37.6±8.9) d, t=2.37, P=0.08) and ipsilateral renal glomerular filtration rates ((41.3±7.6)ml/minuetes vs.(40.5±7.1) ml/min, t=0.78, P=1.27) between the two groups. However, the hospitalization time ((5.9±1.7)days vs. (4.2±1.6) days, t=1.92, P=0.04), postoperative fever rates (4% vs.30%, χ2=5.72, P=0.03) and calculus clearance rates (100% vs. 75%, χ2=7.03, P=0.01) in RPLU were significantly higher than f-UHLL. Besides, 5 patients in the f-UHLL group had postoperative stone residue and were treated with extracorpore shock wave lithotripsy.@*Conclusions@#Both RPLU and f-UHLL are safety and validity for complex upper ureteral calculi. RPLU can improve the rate of calculus removal and reduce the rate of postoperative fever.
