We report on a case of a 72-year-old male with vesical signet-ring cell carcinoma containing a transitional cell carcinoma (TCC) component. It was associated with pure TCC of the right ureter. No other microscopic changes were found in the bladder. The pathogenesis of this signet-ring cell carcinoma is described.  相似文献

Cancer cell seeding inside the urinary tract always has been considered one possible mechanism of the multicentric origin of transitional cell carcinoma (TCC). However, there is still no direct clinical evidence to prove that the natural seeding of TCC is a real event. To our knowledge, we report the first case of spontaneous seeding of TCC of the ureter in the renal tubules of a hydronephrotic kidney. The TCC nature of the intratubular tumor cells has been confirmed by the morphological appearance of them after hematoxylin and eosin staining and positive p53 immunohistochemical staining.  相似文献

Recent technological advances in urological endoscopic surgery of the renal pelvis and proximal ureter via ureteroscopy or percutaneous nephroscopy have made it possible to consider parenchymal-sparing procedures in patients with transitional cell carcinoma. To define the role of these procedures in the management of renal pelvic or proximal ureteral transitional cell carcinoma we analyzed retrospectively 31 patients who underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis and/or proximal ureter. High grade upper urinary tract transitional cell carcinoma and a history of metachronous or synchronous bladder transitional cell carcinoma were independent adverse prognostic factors. However, patients with low grade upper urinary tract transitional cell carcinoma and no evidence of a urothelial field change had a 100 per cent 5-year survival rate. It would appear that parenchymal-sparing endoscopic techniques should be regarded with caution in patients with either high grade transitional cell carcinoma of the renal pelvis and proximal ureter or a history of bladder cancer.  相似文献

The role of adjuvant irradiation in the treatment of transitional cell carcinoma of the renal pelvis and ureter was reviewed. Between June 1966 and March 1981, 41 patients underwent curative resections. A poor risk group was identified, with 23 patients demonstrating disease greater than grade 2 or stage B. Postoperative irradiation was administered to 11 of 23 patients. Median patient followup was 40 months. Two-thirds of all failures occurred within the first 12 months and no failure was seen beyond 35 months. Patients with poor prognostic features had a 60 per cent failure rate compared to 11.8 per cent of the patients with good risk factors (p equals 0.023). The median survival of the 2 groups was 28 and 99 months, respectively (p less than 0.001). Outcome of the poor risk patients was analyzed whether or not the patient received postoperative irradiation. None of the irradiated patients failed with local disease only, while there was 1 patient with local and distant recurrence. In contrast, the nonirradiated group had 5 local failures and twice the number of failures over-all. Median survival of the irradiated and nonirradiated patients was 35 and 26 months, respectively. The number of patients treated is too small to permit valid statistical conclusions and indicates the need for a multi-institutional study to determine if these suggestive findings of improved local control will be corroborated and translate into an improved survival rate.  相似文献

Thirty-three patients in which transitional cell carcinoma was histologically diagnosed in the upper urinary tracts were statistically analyzed. Clinical analysis was done according to a new TNM system proposed by Akaza. Tumor grade and stage well correlated with survival. TS and TE group showed 89.5 and 17.1% 3-year survival, respectively. The survival rates showed significant difference between grade, 1, 2 and 3. T category and grade were also significantly correlated. Furthermore, histology and cytology were well correlated. Finally, prognosis in our series was significantly influenced by stage and grade of the tumor. Prognosis is considered to be good for 1) grade 1, 2) grade 2, superficial tumors with negative cytology, and 3) No and M0 cases. We emphasize that the new classification proposed by Akaza correlates well to survival and adapts well to the definition of regional lymph nodes.  相似文献

Single system ectopic ureterocele associated with transitional cell carcinoma in the ureter has not been described previously. Only two cases of transitional cell carcinoma in a single ectopic ureter have been reported in the published literature. With the development of minimally invasive surgery, we report the first case of single system ectopic ureterocele with transitional cell carcinoma in the distal ureter that was successfully managed by laparoscopic surgery.  相似文献

We report a case of CA19-9 producing urothelial carcinoma of the right ureter. A 61-year-old male patient who had an extremely high value of serum CA19-9 (1,185 U/ml) with right hydronephrosis was referred to us. Magnetic resonance urography and retrograde ureterography revealed a long irregular filling defect in the right distal ureter. Under the diagnosis of right ureteral tumor, we performed right total nephroureterectomy and pelvic lymphadenectomy. The tumor was histologically diagnosed as grade 1 transitional cell carcinoma and pelvic lymphnodes were positive (pT1N2M0). The tumor cells showed positive immunostaining for CA19-9. The serum CA19-9 level was normalized after the operation and successive adjuvant chemotherapy (M-VAC 2 course). No recurrence was found for 15 months after operation. In this case, the serum CA19-9 level was useful as a tumor marker.  相似文献

Ureteroscopy offers an extension of endoscopic diagnosis and treatment to upper urinary tract malignancy. Combination of ureteroscopy and the Nd:YAG laser permits accurate and effective treatment of ureteral neoplasms. Nine highly selected patients, six males and three females, were treated with low grade papillary transitional cell carcinomas of the ureter with at least 24 months follow-up. Follow-up cytology and IVP have indicated no evidence for disease recurrence between the follow-up periods and minimal morbidity to the ureteroscopy and laser treatment. © 1993 Wiley-Liss, Inc.  相似文献

We report on a case of the simultaneous occurrence of cystic renal cell and squamous cell carcinoma in a single kidney in a patient with concurrent transitional cell carcinoma of the ipsilateral ureter and urinary bladder. A review of the literature reveals this to be the first such occurrence.  相似文献

BACKGROUND: Transitional cell carcinoma of the prostate in patients with bladder cancer appears to influence the prognosis and affects the decision about therapeutic modality. Therefore, it is important to characterize transitional cell carcinoma associated with bladder cancer. METHODS: From April 1980 to December 1998, 81 male patients underwent total cystoprostatectomies for transitional cell carcinoma of the bladder. The 81 cystoprostatectomy specimens were examined to clarify the characteristics of prostatic involvement by transitional cell carcinoma. The extent, origin, mode of spread and risk factor of prostatic involvement as well as the prognosis were investigated. In 13 of 15 patients with prostatic involvement the prostate was examined by sequential step sections. RESULTS: Prostatic involvement was observed in 15 of 81 patients (18.5%). Prostatic urethral involvement, invasion to prostatic duct/acinus, prostatic stromal invasion and extraprostatic extension and/or seminal vesicle involvement were recognized in 12 (80%), 14 (93.3%), six (40%), and five (33.3%) of the 15 patients, respectively. Twelve of the 15 patients (80%) with prostatic involvement had papillary or non-papillary tumors (i.e. carcinoma in situ) both in the prostatic urethra and prostatic duct. In 10 of these 12 patients (88.3%), there was contiguity between prostatic urethral and ductal tumors. Seven of the 23 patients (30.4%) with carcinoma in situ of the bladder showed prostatic involvement, which increased to 50% in the presence of carcinoma in situ of the trigone or bladder neck. CONCLUSIONS: Eighty per cent of the patients with prostatic involvement showed papillary or non-papillary tumors both in the prostatic urethra and prostatic duct. There was a high level of contiguity between both tumors. Patients with carcinoma in situ of the trigone or bladder neck revealed significantly higher incidence of prostatic involvement.  相似文献

A total of 50 cases of primary tumors in the renal pelvis and ureter were treated in Tokyo University Branch Hospital (20 cases in 1966-1982) and in Tranomon Hospital (30 cases in 1977-1987). They were composed of 42 men and 8 women (5.3:1) with a mean age of 61 years. 31 patients suffered from renal pelvic tumors, 15 ureteral tumors and 4 tumors in both sites. The tumors were located in the left side in 33 cases, right in 16, and both sides in 1.86% of patients showed gross hematuria. The findings on IVP were filling defect (42%) and nonvisualization (33%). Positive urine cytology was obtained in 12 of 25 cases (48%). Surgery was performed in 47 cases. The remaining 3 cases were with advanced diseases. The surgeries were total nephroureterectomy plus ipsilateral retroperitoneal lymph node dissection in 26 cases, total nephroureterectomy without node dissection in 7, total nephroureterectomy and total cystectomy in 3, nephrectomy in 9, partial nephrectomy in 1 and segmental excision of ureter with ureteroureterostomy in one. Histologically, all tumors were transitional cell carcinoma. Over-all survival rates (Kaplan-Meier's method) of the operated patients at 1, 3, 5 years were 84.2%, 73.1% and 69.4%, respectively. The stage and grade of the tumors affected the prognosis. N factor at lymph node dissection was the most determining factor of prognosis. 3 advanced cases who did not receive surgery for primary site were treated with 5FU in 2, and with CAP in 1.2 of them died of the disease within 1 year after diagnosis, one patient was lost in follow up.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Ectopic ureter is a rare abnormality, so presenting a transitional cell carcinoma (TCC) arising from an ectopic ureter is extremely rare. We report here a case of a man with an invasive transitional cell carcinoma arising from a right ectopic ureter and managed by laparoscopy. To our knowledge, this is the fourth case described in the literature, and the second case of a TCC arising in a right ectopic ureter.  相似文献
