肾移植术后并发自体尿路上皮多器官癌六例的临床分析

Objective To analyze the etiology, clinical diagnosis and outcomes of 6 cases of multifocal urothelial carcinomas following transplantation. Methods A retrospective analysis was performed on 6 cases of multifocal urothelial carcinomas following renal transplantation in our center. Results Six patients were diagnosed as having multifocal urothelial carcinomas, including 1 case of related renal transplantation. Five cases were diagnosed by painless gross hematuria 2～48 months after renal transplantation, and I patient was diagnosed as having bladder tumors by B-uhrasound. All lesions happened un-simultaneously, from 1.5～16 months, and each case accepted operation 2～5 times. One case accepted radical cystectomy and cutaneous ureterostomy of the graft, and one accepted radical cystectomy, cutaneous ureterostomy of the graft and urethrectomy. All of 6 cases received OKT3 or Daclizumab as the induced-immunosuppressive therapy and tacrolimus or cyclosporine A + mycofenolate mofetil + steroid as the maintenance therapy. Intravesical chemotherapy started in all patients immediately after the surgery. All operations were successful and most patients got satisfactory results. Conclusions Kidney recipients have a higher rate of transitional cell carcinomas which are characterized by easy metastasis, and mostly have unsatisfactory prognosis. Kidney recipients with hematuria should be examined carefully with cystoscopy, retrograde pyelography and cystourethroscopy. A routine examination at regular intervals after transplantation is very important.

Combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis

We report here a case of combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis. A 61-year-old female presented with right flank discomfort, microhematuria and progressive renal dysfunction. Following diagnosis of right renal pelvic carcinoma, radical nephroureterectomy with lymph node dissection was performed through a midline incision. The tumor was pathologically diagnosed to be combined small cell carcinoma and sarcomatoid squamous cell carcinoma in the renal pelvis. The patient had no evidence of recurrence or metastasis, 16 months postoperatively. Small cell carcinoma or sarcomatoid squamous cell carcinoma of the renal pelvis is very rare. We believe this is the first such case to be reported in the world.     

Squamous cell carcinoma of renal pelvis: a case report and review of the Japanese literature

Squamous cell carcinoma of renal pelvis is relatively rare and its prognosis is very poor. A 72-year-old man was introduced to our institute because of macroscopic hematuria. He had no history of urolithiasis or urinary tract infection. Excretory urography showed a nonfunctioning right kidney. Cytologic examination of urine was positive for malignant cell from squamous cell carcinoma. Preoperative diagnosis was made as right renal pelvic tumor, but it appeared to be renal tumor on the roentgenogram. Right radical nephrectomy and transurethral ureterectomy was performed. Radiation therapy was done after operation. Pathological diagnosis was squamous cell carcinoma of renal pelvis extensively infiltrating to the renal parenchyma. The patient is alive with no recurrence or metastasis for eight months after operation. Statistical analysis was made on 136 cases of squamous cell carcinoma of renal pelvis reported in the Japanese literature including our case, and this disease is also briefly reviewed.

Squamous cell carcinoma of the renal pelvis and ureter: incidence, symptoms, treatment and outcome

PURPOSE: Squamous cell carcinomas of the renal pelvis and ureter are rare. We report a large series of patients and compare it to patients with urothelial carcinoma. MATERIALS AND METHODS: The initial material was comprised of 808 patients with renal pelvis or ureteral cancer. A review of the histopathological material and clinical records was performed. RESULTS: Only 2 (4%) of 65 patients with squamous cell carcinoma had stage pTa/pT1/pT2 tumors compared to 460 (62%) of 743 patients with urothelial carcinoma. Median survival was much shorter for surgically treated patients with squamous cell carcinoma compared to those with urothelial carcinoma (7 vs 50 months). However, there was no significant difference in the disease specific 5-year survival rate between patients with squamous cell carcinoma and urothelial carcinoma in the same disease stage. Vascular invasion, microscopic solid tumor pattern and large tumor size had negative prognostic significance in multivariate analyses. Histopathological tumor type (squamous cell carcinoma or urothelial carcinoma) had no prognostic significance. CONCLUSIONS: The prognosis for squamous cell carcinoma is poor, but stage for stage the prognosis is not different between patients with urothelial carcinoma and squamous cell carcinoma of the renal pelvis and ureter. It can be presumed that high stage squamous cell carcinoma and urothelial carcinoma become symptomatic first at a time when the tumors already are large, deeply invasive and most often incurable. New treatment modalities are urgently needed to improve the poor prognosis in patients with advanced stage squamous cell carcinoma and urothelial carcinoma of the upper urinary tract.     

Clinical study of carcinoma of the penis

We reviewed six cases of carcinoma of the penis seen at our department during the last 12 years. The mean age and mean followup period were 56 +/- 11 years and 53 +/- 42 months, respectively. Inguinal lymphadenopathy was evident in all patients, one of whom was diagnosed as having nodal metastasis because of the persistence of adenopathy after antimicrobial therapy. Four patients, had Jackson Stage 1, 1 Stage 2 and 1 Stage 3 cancer. The patient with Stage 3 cancer underwent total penectomy and bilateral inguinal lymphadenectomy. He died of cancer 2 years after the operation. The 5 patients with stage 1 or 2 underwent partial penectomy without lymphadenectomy. Pathological examination showed moderately differentiated squamous cell carcinoma (SCC) in 2 patients with stage 2 and 3 cancer, well differentiated SCC in 3 and verrucous carcinoma in the other patient with stage 1 cancer. Prophylactic external radiation therapy to the groin was performed in 3 of the 4 patients with invasion to corpus spongiosum (pT2). Two of the 3 patients developed mild radiation dermatitis, and no major complications were observed. The 5 patients with clinically negative nodes showed no evidence of recurrence after surgery. As reported by others, inguinal node metastasis appears to worsen the prognosis of patients with carcinoma of the penis.

Cyclophosphamide-induced renal pelvic tumor--a case report

We report a case of transitional cell carcinoma in the left renal pelvis, which occurred in a 24-year-old man. He had been treated with cyclophosphamide (CPM) for a period of 27 months for retroperitoneal rhabdomyosarcoma diagnosed at the age of 10. At first 1.2 g CPM had been given twice intravenously for 3 months, followed by oral administration of 41 g CPM for 23 months. Drip infusion pyelography revealed a filling defect in the left renal pelvis. A left renal pelvic tumor was strongly suspected on computerized tomography and magnetic resonance imaging. Left nephroureterectomy was then performed. Histological diagnosis of the left renal pelvic tumor was transitional cell carcinoma, grade 2, pT1N0M0. No recurrence was defected 17 months later. This case seems to be the second case of cyclophosphamide-induced upper urothelial carcinoma reported in Japan.

STAGE SPECIFIC GUIDELINES FOR SURVEILLANCE AFTER RADICAL NEPHRECTOMY FOR LOCAL RENAL CELL CARCINOMA

Purpose

We report stage specific followup guidelines based on our evaluation of the pattern of recurrence in 286 patients treated for local N0 or Nx renal cell carcinoma.

Materials and Methods

We retrospectively reviewed the clinical records of 286 patients with pT1 to pT3N0 or Nx renal cell carcinoma who underwent nephrectomy at our center between February 1985 and December 1994. In cases of later metastases the median interval to first metastasis, site of metastasis and method of diagnosis were correlated with the primary lesion stage.

Results

Metastases developed in 68 patients a median of 23 months after nephrectomy. Eight of the 113 patients with pT1 disease had metastases (median time to diagnosis 38 months), while 17 of 64 with pT2 disease and 43 of 109 with pT3 disease had metastases (medians 32 and 17 months, respectively). Of the 92 metastases 59 (64%) were asymptomatic, including 44 detected on routine chest x-rays (32) and blood tests (12). Isolated asymptomatic intra-abdominal metastases were diagnosed by surveillance computerized tomography in only 6 patients (9%). The remaining patients with metastases had associated clinical symptoms and/or abnormal results on interval tests that prompted further diagnostic studies.

Conclusions

We confirmed that the risk of metastatic renal cell carcinoma is stage dependent. Therefore, surveillance protocols should be based on the pathological stage of the primary tumor. We recommend an annual chest x-ray, and serum liver function and alkaline phosphatase level tests for patients with pT1 disease. These studies are indicated beginning at 6 and 3 months for pT2 and pT3 disease, respectively, continuing every 6 months for 3 years and then annually. Surveillance computerized tomography should be performed at 24 and 60 months in patients with pT2 and pT3 disease or earlier when the results of any routine study are abnormal or clinical symptoms are present. Bone and brain surveillance studies should be prompted by site specific symptoms, elevated alkaline phosphatase levels or the diagnosis of metastasis at another site.
