Transitional cell carcinoma (TCC) of the bladder or renal pelvis is rare in children. We report 2 children with TCC of the bladder and 1 with TCC of the renal pelvis. One of the two children with bladder carcinoma experienced frequent intravesical recurrences, which is in contrast to the usual clinical course of bladder carcinoma in children. In the 3rd child, renal pelvic carcinoma was found incidentally in a renal pelvis specimen removed during pyeloplasty. 相似文献

目的 分析肾移植受者泌尿系统恶性肿瘤的发病情况,并探讨其发病机理及治疗方法.方法 回顾性分析1978年至2010年12月间肾移植受者发生泌尿系统恶性肿瘤22例的资料.结果 22例的病理检查结果分别为膀胱移行上皮细胞癌9例(其中1例第3次手术后发现转化为腺癌),膀胱鳞状细胞癌1例,膀胱腺癌1例,肾透明细胞癌3例(其中2例为双侧肾癌),肾低分化癌1例,肾盂移行细胞癌1例,肾盂+膀胱移行细胞癌1例,输尿管移行细胞癌2例,输尿管+膀胱移行细胞癌2例,输尿管移行细胞癌+膀胱腺癌1例.肾癌及输尿管癌均发生在患者原肾及输尿管.11例膀胱癌患者中9例存活,均保有全部或部分肾功能;4例肾癌患者均在发病后半年内死亡;肾盂癌、输尿管癌除2例术后早期死亡外,其余5例存活.22例发现肿瘤后1年存活率为73.7%.结论 肾移植后泌尿系统恶性肿瘤可见少见的病理类型.治疗中应注意免疫抑制剂的使用和移植肾功能保护的问题.肾实质性恶性肿瘤预后很差.Abstract: Objective To investigate the incidence of urological malignancy in renal allograft recipients and explore the mechanism of increased incidence in China and the management. Methods A retrospective study was performed on 22 patients with urological malignancy in renal allograft recipients between 1978 and 2010. Results Twenty-two cases of urological malignancy were diagnosed by pathologic evidence, including 9 cases of transitional cell carcinoma (TCC) of bladder, 1 case of squamous cell carcinoma of bladder, 1 case of adenocarcinoma of bladder, 1 case of TCC of pelvis, 1 case of TCC of bladder and pelvis, 1 case of TCC of ureter complicated with adenocarcinoma of bladder, 2 cases of TCC of ureter, 2 cases of TCC of ureter and bladder, 3 cases of clear cell carcinoma of kidney, and 1 case of undifferentiated carcinoma of kidney. All the malignancies belonged to native organs. All the patients suffering bladder cancer had normal function of allograft. Five patients with TCC of pelvis or ureter survived and 2 cases died early after operation. All the patients suffering renal carcinoma deceased within 6 months after diagnosis. One-year survival rate was 73. 7 % after the diagnosis of urological malignancy. Conclusion Urological malignancy ranked highest in malignancy in renal allograft recipients, and rare pathological types of urological malignancy in non-renal allograft recipients are often demonstrated. The strategy of treatment should take consideration of the relationship between the usage of immunosupressive agents and the preservation of allograft function. It is critical for the therapy of malignancies to possess satisfactory allograft function. The prognosis of renal cell carcinoma is poor. 相似文献

Transitional cell carcinoma (TCC) of the bladder is a solid tumor that induces angiogenesis to maintain nutrition and oxygenation of tumor cells. Maspin, a serpin with tumor suppressing activity, has recently been identified as an inhibitor of angiogenesis. This study examined the impact of maspin expression in the growth pattern of TCC of the bladder. Maspin was identified in a panel of normal tissues, in several bladder carcinoma cell lines, and 51 patient samples of TCC of the bladder. Expression was detected by RT-PCR and immunohistochemistry. Furthermore, the level of maspin was correlated to the growth rate of bladder tumor cell lines in vitro and in vivo. Maspin expression was found in high quantities in normal urothelium. Maspin expression was preserved in superficial bladder cancers but was significantly diminished in invasive carcinomas. Within the group of invasive TCCs, maspin expression was inversely correlated to the patient prognosis. Furthermore, low maspin expression level was coupled to an increased tumor cell growth in vivo. Down-regulation of maspin expression seems to be a specific event in the progression of invasive bladder carcinoma. Maspin might be a useful marker to determine the prognosis of invasive TCC. Furthermore, maspin re-expression might become a therapeutic option in the treatment of invasive, metastatic TCC.This study was supported in part by Medac GmbH. 相似文献

ObjectivesStudy TGF-β1 pathway in bladder carcinoma.Design and methodsEighty-one patients were enrolled: 16 chronic cystitis and 60 malignant bladder lesions; 15 schistosomal squamous cell carcinoma (SQCC), 45 transitional cell carcinoma (TCC). Five healthy individuals served as controls. mTGF-β1, protein, and its receptor expression in urine and bladder tissue were measured using in situ hybridization and immunohistochemical techniques, respectively.ResultsOverexpression of TGF-mRNA in invasive TCC group was compared with superficial TCC, high grade TCC was compared with low grade, and SQCC was compared with TCC. TGF-β1 protein and its receptor I (TGF-βR1) were overexpressed in urine samples in malignant group compared with chronic cystitis and in SQCC group compared with TCC group. TGF-ß1 protein and its receptor were significantly increased in schistosomal malignant group compared with non-schistosomal group.ConclusionExpression of TGF-ß1 and TGF-ßR1 could be used as biological markers of bladder carcinoma. 相似文献

Transitional cell carcinoma (TCC) of the bladder in children is a rare occurrence. Cyclophosphamide is a known risk factor for the development of TCC. Other alkylating agents, such as nitrogen mustard, have not been implicated in the development of secondary adult or pediatric TCC. The role of radiotherapy in the development of secondary malignancies of the bladder remains controversial. We report a case of childhood TCC in a patient in remission from Hodgkin's lymphoma previously treated with non-cyclophosphamide chemotherapy and low-dose nodal radiotherapy. 相似文献

We present a case of cutaneous metastases from a primary bladder transitional cell carcinoma (TCC), with a prolonged survival of 23 years. Cutaneous metastases from primary bladder TCC are uncommon and, like all metastases, have a poor prognosis. The common modality of treatment of cutaneous metastases from a primary bladder cancer is wide local excision of the metastases followed by combination chemotherapy. Here, we present a case of a solitary cutaneous metastasis from a primary bladder TCC, which was treated with wide local excision and single agent chemotherapy. Twenty-three years on, the patient remains disease and recurrence free. 相似文献

Specimens from 334 Chinese patients who underwent surgical treatment for bladder tumours over a 6 year period were studied retrospectively. Transitional cell carcinoma (TCC) accounted for 91.3% of all the bladder tumours. The male to female ratio was 3:1 and the mean age was 69 years. Papillary TCC, which represented 67.5% of all TCC, were more often of a lower grade compared to non-papillary tumours. The staging of tumours was done for the 102 cystectomy specimens with TCC only. Among these, 28% were superficial while 72% were muscle-invasive and the papillary TCC usually presented at an earlier stage. Infiltration into the prostate gland was identified in 11% of male patients while coexisting adenocarcinoma of the prostate was observed in another 4.2%. Other types of carcinoma were uncommon. Squamous cell carcinoma, adenocarcinoma and small cell carcinoma accounted for 2.7, 1.8 and 0.6% of all bladder tumours, respectively. A rare case of sarcomatoid carcinoma was also found, but no true sarcoma was documented in this series. Benign lesions included five inverted papillomas, three nephrogenic adenomas, two paragangliomas and one haemangioma. 相似文献

OBJECTIVE: Primary transitional cell carcinoma (TCC) of the upper urinary tract represents 6-8% of all TCC cases. Nephroureterectomy with removal of a bladder cuff is the treatment of choice. The rates of TCC recurrence in the bladder after primary upper urinary tract surgery described in the literature range between 12.5 and 37.5%. In a retrospective analysis we examined the occurrence of TCC after nephroureterectomy for upper tract TCC in patients without a previous history of bladder TCC at the time of surgery. METHODS: Between 1990 and 2002, 29 patients underwent primary nephroureterectomy for upper tract TCC. The mean age of the patients was 69.5 years. In 5 cases upper urinary tract tumors were multilocular, in the remaining cases unilocular in the renal pelvis (n=12) or the ureter (n=12). The follow-up was available for 29 patients with a mean follow-up of 3.37 (0.1-11.2) years. RESULTS: 11/29 (37.9%) patients had TCC recurrence with 9/11 patients having bladder TCC diagnosed within 2.5 years (0.9-6.0) after nephroureterectomy. 13/29 patients are alive without TCC recurrence, 3/29 patients died due to systemic TCC progression and 5/29 died of unrelated causes without evidence of TCC recurrence. CONCLUSION: Our data indicate a high incidence of bladder TCC after nephroureterectomy for primary upper tract TCC of up to 6 years after primary surgery. Because of the high incidence of bladder TCC within the first 3 years of surgery, careful follow-up is needed over at least this period. 相似文献

PURPOSE: The effect of bladder cancer histological subtypes other than transitional cell carcinoma (nonTCC) on clinical outcomes remains uncertain. We conducted a multi-institutional retrospective study of patients with bladder cancer treated with radical cystectomy to assess the impact of nonTCC histology on bladder cancer specific outcomes. MATERIALS AND METHODS: A total of 955 consecutive patients underwent radical cystectomy with bilateral pelvic lymphadenectomy for bladder cancer at 3 academic institutions. TCC was present in the radical cystectomy specimen in 888 patients (93%). NonTCC histology was present in 67 patients (7%), including squamous cell carcinoma in 26, adenocarcinoma in 13, small cell carcinoma in 10 and other nonTCC subtypes (ie spindle cell carcinoma, carcinosarcoma and undifferentiated carcinoma) in 18. For patients alive at last followup median followup was 39 and 23 months for patients with TCC and nonTCC histologies, respectively. Bladder cancer specific progression and survival were assessed using Kaplan-Meier and multivariate Cox proportional hazards analyses. RESULTS: Bladder cancer specific progression and mortality did not differ significantly between patients with SCC and TCC histologies. Patients with nonTCC and nonSCC bladder cancer were at significantly increased risk for progression and death compared to patients with TCC or SCC (p <0.001). This association remained statistically significant in patients with organ confined disease (stage pT2 or lower) and patients with nonorgan confined disease (stage pT3 or higher) (p <0.001). In a multivariate analysis nonTCC and nonSCC histology was associated with an increased risk of bladder cancer progression and death (OR 2.272 and 2.585, respectively, p <0.001), even after adjusting for final pathological stage, lymph node status, lymphovascular invasion and neoadjuvant or adjuvant treatments. CONCLUSIONS: NonTCC and nonSCC histological subtype is an independent predictor of bladder cancer progression and mortality in patients undergoing radical cystectomy for bladder cancer. Patients with bladder TCC and SCC share similar stage specific clinical outcomes. 相似文献
