    Objectives: To identify the variables predictive of contralateral metachronous upper urinary tract transitional cell carcinoma (UUT-TCC) after nephroureterectomy (NFU) for non-metastatic UUT-TCC. Methods: Clinical and pathological data of 234 patients who had undergone NFU for UUT-TCC from 1989 to 2005 in three European urological centers were retrospectively collected and analyzed. Results: The median follow-up duration for the whole cohort was 34 months. Contralateral metachronous UUT-TCC was detected in 14 patients (6%). Three patients were treated by NFU, while seven patients underwent ureterectomy and reimplantation and four patients were treated by endoscopic resection plus bacillus Calmette,Guérin instillations within the UUT through a nephrostomic tube. On univariate analysis, a prior history of bladder TCC before NFU was the only factor predictive of the occurrence of contralateral UUT-TCC. Specifically, the 5-year probabilities of being free from contralateral UUT-TCC were 96.6% for the patients with de novo UUT-TCC, and 91.1% and 55.3% for those having non-muscle-invasive and muscle invasive bladder TCC before the UUT cancer, respectively. All survival differences were statistically significant (no history of bladder TCC vs history of non-muscle-invasive bladder TCC, log rank P value 0.015; history of non-muscle-invasive bladder TCC vs history of muscle-invasive bladder TCC, log rank P value 0.035). Conclusions: In our multicenter dataset of patients who had undergone NFU for UUT-TCC, contralateral metachronous UUT-TCC occurred in 6% of the patients. A prior history of bladder TCC before NFU was the only variable predictive of UUT recurrence at univariate analysis. [source]

    Objectives: To evaluate the efficacy of adjuvant platinum based chemotherapy in upper urinary tract urothelial cancer following surgical resection in terms of survival benefit and inhibition of bladder cancer recurrence. Methods: Between April 1986 and August 2005, a total of 132 patients with a diagnosis of upper urinary tract urothelial cancer underwent radical nephroureterectomy with cuff of bladder at our department. A total of 46 patients (13 with pT2pN0M0 and 33 with pT3 pN0M0 transitional cell carcinoma without prior bladder cancer) were enrolled. Patients with locally advanced disease were divided into two groups: the adjuvant chemotherapy group (24 patients) who received adjuvant methotrexate, vinblastine, adriamycin, and cisplatin (M-VAC) and the non-adjuvant chemotherapy group who did not receive adjuvant M-VAC (22 patients). Results: There were no statistically significant differences in patient characteristics or 10-year survival between the two groups. The recurrence rate in the non-adjuvant chemotherapy group was significantly higher than in the adjuvant chemotherapy group (log-rank test, P < 0.0001). Only non-adjuvant chemotherapy was a significant and independent risk factor (hazard ratio 6.97) for the development of intravesical recurrence (P < 0.01). Conclusion: Adjuvant M-VAC is an important optional adjuvant therapy and can prevent recurrent bladder tumors following surgery for upper urinary tract transitional cell carcinoma. To determine whether adjuvant chemotherapy has further benefit, a randomized study would be needed. [source]

    Objective:, To report the oncological outcome of retroperitoneoscopic nephroureterectomy (RNU) with bladder cuff excision for upper urinary tract transitional cell carcinoma (TCC), and to compare the outcome with that of the traditional open nephroureterectomy (ONU). Patients and methods:, From January 2001, 48 patients with upper urinary tract TCC were enrolled in the study; 25 had RNU and 23 had ONU. Oncological parameters (disease-free survival and disease-specific survival) were calculated from the time of surgery to the date of last follow up and were analysed by the Kaplan,Meier method. Results:, Mean follow up was 24.3 months in the RNU group, significantly shorter than in the ONU group. Bladder recurrence was identified in two patients with grade 3 pathological stage pT3, one patient with grade 3 stage pT2 disease and two patients with grade 2 stage pT2 disease. Multiple organ metastases in the lung, liver and lymph nodes were associated with bladder recurrence in two cases (grade 2 stage pT3, and grade 3 stage pT3). The recurrence rate was 20% (5 of 25 cases) and mean time to recurrence was 9.5 months. In the ONU group, bladder recurrence and metastases developed in four and three patients, respectively. The recurrence rate was 17% (4 of 23 cases) and mean time to recurrence was 23.4 months. No significant difference was detected in the disease-free survival rate and cancer-specific survival rate between the two groups (P = 0.759 and P = 0.866, respectively). Conclusion:, The oncological outcome of RNU appears to be equivalent to that of ONU. Moreover, long-term follow up is necessary to evaluate the oncological outcome in comparison to ONU. [source]


    Role of ureteroscopic biopsy in the management of upper urinary tract malignancy

    Abstract Background:, The aim of the study presented here was to examine the accuracy of ureteroscopic biopsy in the diagnosis of upper urinary tract transitional cell carcinoma (TCC) and whether nephron-sparing management (holmium YAG laser, transurethral resection or partial ureterectomy) is possible or not based on pathological diagnosis. Methods:, Forty consecutive patients underwent ureteroscopic biopsy with the use of 3-Fr cold cup forceps. Pathological diagnosis of the biopsy sample and grade or stage of surgically resected tumors were compared. In patients with grade 1 or 2 TCC diagnosed by ureteroscopic biopsy, the disease-free and survival rates determined whether nephron-sparing management was performed or not. Results:, There were no major complications associated with ureteroscopic biopsy. The pathological grading of the biopsy specimen was almost the same as that of the surgically resected specimen. Eighty five percent of grade 2 or 3 TCC showed muscle invasive disease. There were no significant differences in the disease-free and survival rates between the nephroureterectomy and the nephron-sparing management groups, except for grade 3 or pT3 tumors. Conclusion:, Ureteroscopic biopsy is safe and accurate if sufficient tissue sample is obtained. Ureteroscopic biopsy should be performed in patients who require nephron-sparing management. Nephroureterectomy can be avoided if the tumor is confirmed as low-grade. [source]

    OBJECTIVE To evaluate the stage- and grade-specific survival rate in patients with upper urinary tract (UUT) transitional cell carcinoma (TCC) after open (ONU) or hand-assisted laparoscopic nephroureterectomy (LNU) with bladder-cuff excision. PATIENTS AND METHODS From January 1998 to April 2005, 143 patients with UUT-TCC were treated with either ONU or LNU and enrolled in the study. The peri-operative data were collected by retrospective chart review. The recurrence, metastasis and survival rate were calculated. RESULTS The 5-year disease-specific survival of patients with pT1 disease was 88.1% after ONU and 92.0% after LNU (P = 0.745); the respective values for patients with pT2 were 11/17 and 12/15 (P = 0.874), and for pT3 were six/11 and 12/15 (P = 0.476). The incidence of bladder recurrence within 2 years after surgery was 24.7% for ONU and 19.7% for LNU (P = 0.475). CONCLUSION The results were similar after ONU or LNU with bladder-cuff excision; bladder-cuff excision using a hand-assisted device is effective and serves as a treatment option for patients with UUT-TCC.

    Renal diagnosis of chronic hemodialysis patients with urinary tract transitional cell carcinoma in Taiwan

    CANCER, Issue 8 2007
    Chung-Hsin Chang MD
    Abstract BACKGROUND. Transitional cell carcinoma (TCC) is the most common malignancy in dialysis patients of Taiwan. The reason for such a high incidence of TCC is undetermined. The correlation between the underlying renal disease and the development of TCC was investigated. METHODS. The authors retrospectively reviewed the clinical data and outcome of 1537 chronic hemodialysis (HD) patients from 1993 to 2002. The incidence of TCC was computed. The Cox regression method was used to analyze the role of potential risk factors. RESULTS. After a mean dialysis duration of 46.5 months, 26 (1.69%) patients with TCC were diagnosed. The standardized incidence ratio (SIR) of TCC was 48.2 as compared with the general population and the SIR of TCC seemed higher in women (65.1) and in the age group 50 to 54 years (173.6). Of them, most cases showed no definite etiology. All these cases showed bilateral contracted kidneys. Nonnephrotic proteinuria was found in all cases and trace glucosuria was found in 17 (65%). Painless gross hematuria was the cardinal symptom and distant metastasis was rare. Also, TCC in upper urinary tracts were common and found in 14 (54%) of patients. Age at the time of dialysis, female sex, compound analgesic use, and Chinese herb use had statistical significance as risk factors (P < .05). CONCLUSIONS. Chronic HD patients have a high risk of TCC in Taiwan, especially in female and middle-aged patients. The study indicated that chronic tubulointerstitial nephritis (CTIN) is the most likely underlying renal disease in HD patients with TCC, a high percentage of the CTIN related to the usage of Chinese herbs or compound analgesics may contribute to the development of TCC, whereas diabetes or chronic glomerulonephritis play only a minor role.

    A comparison of the pathology of transitional cell carcinoma of the bladder and upper urinary tract

    BJU INTERNATIONAL, Issue 6 2005

    OBJECTIVE To clarify the histopathological patterns of upper and lower urinary tract transitional cell carcinomas (TCCs), as previous reports suggest that upper urinary tract TCCs have a greater tendency towards high-grade disease than bladder TCCs, of which most are low-grade and low-stage tumours. PATIENTS AND METHODS All patients presenting with TCC of bladder or upper urinary tract between February 1991 and December 2001 at one institution were identified. Further patient information was obtained from the hospital database and case-note review. RESULTS In all, 164 patients with upper urinary tract TCC and 2197 with bladder TCC were identified. There was a correlation between grade and stage of both upper urinary tract and bladder TCCs. 35% of the upper tract TCCs were classified as grade 2 and 44% as grade 3, while for bladder TCCs, 31% of lesions were classified as grade 2 and 35% as grade 3 (P = 0.003). Of the upper urinary tract lesions 33% were stage pT2,T4, compared with only 20% of bladder TCCs (P = 0.001). CONCLUSIONS Upper urinary tract TCC is a higher grade and stage disease than bladder cancer, a finding that emphasizes the need for aggressive treatment of upper urinary tract TCC. If endourological management of upper urinary tract TCC is considered, histopathological determination of tumour grade before treatment is essential. [source]
