    • 摘要: 目的 探讨未发生远处转移的膀胱移行细胞癌患者发生第二原发癌(SPM)的影响因素.方法 选取监测、流行病学和最终结果(SEER)数据库中1988年至2016年诊断为未发生远处转移的膀胱移行细胞癌患者,使用竞争风险模型中的累积发生率函数(CIF)对选取患者发生第二原发癌的影响因素进行单因素分析,使用Fine-Gray模型进行多因素分析.结果 共纳入154725例未发生远处转移的膀胱移行细胞癌患者.多因素分析结果显示,婚姻状态、年龄、种族、性别、肿瘤是否浸润肌层、放疗、手术和化疗是发生SPM的影响因素(P<0.05).结论 未发生远处转移的膀胱移行细胞癌患者应行SPM发生风险筛查,以指导治疗、检测和随访计划.

    • 摘要: Objective To investigate the clinical expression of human epididymal protein 4(HE4)in patients with transitional cell carcinoma(TCC)and its association with oncologic features.Methods Sixty patients with TCC in the urinary system in Department of Urology,Houjie Hospital of Dongguan City from June 2015 to May 2017 were selected as TCC group,and 60 patients with benign urological diseases were selected as benign group.Another 60 sub-jects with healthy physical examination results were enrolled as the control group.HE4 levels in three groups were de-tected and compared.Results HE4 expression level in TCC group was(279.87±18.92)pmol/L,which was significant-ly higher than(77.69±8.35)pmol/L in the benign group and(68.32±7.72)pmol/L in the control group(P0.05). The positive rate of HE4 in non-muscle invasive TCC was 83.3%,which was significantly higher than 23.3% in the benign group and 15.0% in the control group(P0.05).Conclusion There was no correlation between the expression level of HE4 and the oncologic characteristics of TCC patients, but the expression and positive rate of HE4 in patients with TCC were significantly increased,especially in non-muscle invasive TCC pa-tients,which shows that HE4 can be used as an indicator for early diagnosis and monitoring of TCC.%目的 研究人附睾蛋白4(HE4)在移行细胞癌(TCC)患者中的临床表达水平及其与肿瘤学特征的关联性.方法 选取2015年6月至2017年5月间于东莞市厚街医院泌尿外科住院接受手术治疗的泌尿系统TCC患者60例为TCC组,泌尿系统良性疾病患者60例为良性组,体检结果健康的60例为对照组.检测三组受检者的HE4水平并进行对比分析.结果 TCC组患者的HE4表达水平为(279.87±18.92)pmol/L,明显高于良性组的(77.69±8.35)pmol/L和对照组的(68.32±7.72)pmol/L,差异均有统计学意义(P0.05);HE4在非肌层浸润性TCC患者中的阳性率为83.3%,明显高于良性组23.3%和对照组15.0%,差异均有统计学意义(P0.05).结论 HE4的表达水平和TCC患者的肿瘤学特征间无关联性,但其在移行细胞癌患者中的表达和阳性率显著增高,且非肌层浸润性移行细胞癌患者的HE4表达和阳性率也显著增高,这一特异性表明HE4可以作为移行细胞癌的早期诊断和监测指标.

    • 摘要: 目的探讨桔梗皂苷D对人移行细胞癌5637细胞诱导凋亡作用及分子机制。方法 HE染色和透射电子显微镜观察细胞的形态学变化;流式细胞学技术检测细胞凋亡率的变化;Western blot法检测凋亡通路相关蛋白的表达变化;PCR法检测p53、Bcl-2、Bax mRNA表达;免疫组织化学法检测凋亡相关蛋白表达的影响。结果通过HE染色和电子显微镜观察桔梗皂苷D组5637细胞,可见凋亡细胞,凋亡指数明显高于对照组(P<0.01);与对照组细胞相比,桔梗皂苷D组5637细胞Survivin、Livin表达量明显下降(P<0.05);Caspase-9、Caspase-8、Caspase-3、Cyt-c表达量与对照组比较,明显增加(P<0.05);p53、Bax mRNA水平明显升高,Bcl-2 mRNA表达下降(P<0.01);Bax、Caspase-9、Caspase-8以及Caspase-3表达较对照组增多,而Bcl-2表达则明显下降(P<0.01)。结论桔梗皂苷D能诱导人移行细胞癌5637细胞凋亡,其作用机制可能与上调Caspase-9、Caspase-8、Caspase-3、Cyt-c、p53和下调Bcl-2表达、激活线粒体途径和死亡受体途径有关。

    • 摘要: Objective To investigate the efficiency and safety of transurethral bipolar plasmakinetic resection of the bladder tumor ( PK-TURBT) in renal transplant recipients , and to evaluate the risk factors of postoperative recurrence of tumor . Methods This retrospective study included 16 cases of clinically diagnosed superficial bladder tumors after renal transplantation .They were treated by PK-TURBT and followed by intravasical instillation from September 2009 to June 2014.In procedures , we vapo-resected and removed bladder tumors , reaching the deep muscle layer of the bladder .Risk factors of tumor recurrence were evaluated with Cox ’ s proportional hazards regression model analysis . Results The procedures of PK-TURBT were performed successfully with a mean operation time of 34.1 min (range, 15 -60 min).Of the cases, 8 cases (8/16, 50.0%) developed recurrence during a median follow-up period of 45 months (range, 14-62 months).Among them, 7 cases (7/8,87.5%) developed recurrence within 2 years after PK-TURBT.By multivariate analyses , native aristolochic acid nephropathy ( HR=7.040, 95% CI: 1.411 -35.121, P =0.017) and tumor size ≥3 cm (HR=8.230, 95%CI:1.055-59.834, P=0.046) were identified as independent predictors for the development of recurrence after PK-TURBT for bladder cancer in renal transplant recipients . Conclusions Transurethral bipolar plasmakinetic resection of the bladder tumor is effective for superficial bladder carcinoma after renal transplantation , with low risk of complications .The incidence of postoperative recurrence is high , and most subsequent cancers recur within 2 years after surgery .The recurrence risk is higher in cases with native aristolochic acid nephropathy and tumor size ≥3 cm.%目的:探讨经尿道双极等离子电切治疗肾移植后膀胱肿瘤的疗效和安全性,评价术后肿瘤复发的危险因素。方法2009年9月~2014年6月采用经尿道双极等离子电切术治疗肾移植术后膀胱肿瘤16例,术中汽化切割肿瘤直达深肌层,术后定期膀胱灌注化疗。术后患者定期随访,观察肿瘤复发情况。采用Cox比例风险回归模型分析影响肿瘤复发的危险因素。结果16例均成功完成经尿道双极等离子电切术,平均手术时间34.1 min(15~60 min)。术后随访时间14~62个月,中位随访时间45个月,肿瘤复发率50.0%(8/16),其中87.5%(7/8)术后2年内复发。多因素分析表明,原肾马兜铃酸肾病(HR=7.040,95%CI:1.411~35.121,P=0.017)与肿瘤直径≥3 cm(HR=8.230,95%CI:1.055~59.834,P=0.046)是术后复发的危险因素。结论经尿道双极等离子电切术是治疗肾移植术后非肌层浸润膀胱肿瘤的有效方法,切除效率高,安全性较好。术后仍有较高的复发率,大多数病例术后2年内复发,原肾马兜铃酸肾病、肿瘤直径≥3 cm的患者,术后复发风险较高。

    • 摘要: Objective To evaluate the efficacy and safety of ureteral stenting after transurethral resection ( TUR) of bladder tumors involving the ureteral orifice.Methods From March 2009 to November 2015,34 cases of non-muscle invasive bladder tumor including 28 male and 6 female aged from 26 to 79 years( mean 51 years) were treated by TUR.14 cases had single tumor and 20 had multiple tumors,and 29 were primary and 5 were recurrent.All the patients had tumors involving the ureteral orifice without preoperative hydronephrosis revealed by IVU or CTU examination.The tumors were resected into the deep muscle layer and the involved ureteral orifices were resected during the procedure,and after that a double-J ureteral stent was placed in 18 cases.All patients received one immediate intravesical instillation of 50mg epirubicin after TUR, and further scheme of adjuvant intravesical chemotherapy instillations were made according to the pathological diagnosis.Ureteral stents were removed 10-12 weeks after TUR,and cystoscopy and urinary tract ultrasound examinations were performed every 3 months for 1-2 years postoperatively. Results The operations were successful without complications.No serious adverse reaction occurred in immediate and further adjuvant intravesical chemotherapy.During the follow-up period of 3-71 months, no ureteral stricture, hydronephrosis or tumor recurrence in the upper urinary tract occurred in all the 18 patients with ureteral stent, and the resected ureteral orifices recovered well with normal appearance and ejecting urine.Hydronephrosis was observed in 3 of 16 patients without ureteral stent including 2 cases of nontumoral stenosis at the ureterovesical junction requiring ureteral reimplantation and 1 case of lower ureteral tumor on the involved side requiring nephroureterectomy and bladder cuff excision.No patient complained of symptoms secondary to vesicoureteral reflux or continuous unrelievable lower urinary tract symptoms.2 cases of bladder tumor recurred out of the resected area.Conclusions Ureteral stenting after TUR of bladder tumors involving the ureteral orifice can prevent stricture at the ureterovesical junction without increasing the risk of tumor cell seeding along the upper urinary tract.The existence of a double-J ureteral stent does not increase complications of adjuvant intravesical chemotherapy, and also won't cause intolerable lower urinary tract symptoms.%目的:探讨累及输尿管口的膀胱肿瘤电切术后留置输尿管支架管(双J管)的疗效和安全性。方法回顾性分析2009年3月至2015年11月收治的累及输尿管口的非肌层浸润性膀胱肿瘤患者34例,男28例,女6例。年龄26~79岁,平均51岁。肿瘤单发14例,多发20例;初发29例,复发5例。术前IVU或CTU检查证实患侧输尿管无扩张、积水。34例均行TURBT,切除肿瘤达深肌层,输尿管口完全切除,其中18例术毕于患侧输尿管内留置双J管1根。所有患者术后即刻膀胱内灌注表柔比星50 mg,其后根据病理报告制定膀胱内灌注化疗方案。术后10~12周于膀胱镜下拔除双J管,术后1~2年内每3个月复查。结果34例手术均顺利完成,无手术并发症。术后即刻膀胱内灌注化疗及后续灌注化疗过程中均无严重不良反应发生。随访3~71个月,18例留置双J管者均未发生输尿管狭窄或肾积水,上尿路未发现肿瘤复发,膀胱镜检查见输尿管口外观及喷尿正常;16例未留置双J管者中3例出现肾积水,其中2例证实为患侧输尿管口瘢痕狭窄,行输尿管膀胱再吻合术治疗,1例证实为患侧输尿管肿瘤行根治性切除术。34例患者均无膀胱输尿管反流的症状,均无持续的不可缓解的下尿路症状。膀胱内肿瘤复发2例,复发部位均不在原电切创面区域。结论累及输尿管口的非肌层浸润性膀胱肿瘤行TURBT术毕于患侧输尿管内留置双J管可减少术后输尿管口狭窄的发生率,且未发现增加肿瘤细胞逆行种植上尿路的风险。双J管的存在不会增加膀胱内灌注化疗的并发症,也不会引起不可耐受的下尿路症状。

    • 摘要: 犬膀胱肿瘤大约占犬所有肿瘤病的1%,约占犬恶性肿瘤的2%[1]。多数膀胱肿瘤发生于8岁以上犬。在某些梗类品种中,雌性的膀胱肿瘤发生率高于雄性,未绝育犬高于绝育犬。犬泌尿道肿瘤中最常见的恶性肿瘤是移行细胞癌,其他的类型如纤维肉瘤、鳞状细胞癌、腺癌和其他间质肿瘤等鲜见报道[2]。笔者近日在临床诊疗中遇到一例犬膀胱纤维肉瘤病
