Primary Small Cell Carcinoma of the Bladder: A Report of 25 Cases

Primary small cell carcinoma of the bladder is a rare condition with approximately 100 cases reported to date. An incidence of 0.7 percent small cell carcinoma was found in a total series of bladder tumors diagnosed in Western Sweden during a 2-year period. We describe 22 patients with primary small cell carcinoma followed to death or for at least 6 years. Three additional cases were diagnosed at autopsy. Of 18 patients with stages T2M0 to T4M0 cancer treated with locoregional therapy 5 (28 percent) had no evidence of disease after a median observation of 10 years (range 6 to 18) and 13 died of disease after 0.5 to 19 months (median 7.3). Two patients with metastatic disease were treated with systemic chemotherapy but died within 15 months. Two patients died shortly after the diagnostic biopsy. Our study and a review of the literature indicate that primary small cell carcinoma of the bladder is less aggressive than its pulmonary counterpart and that some patients can be cured by transurethral resection, or partial or radical cystectomy combined with radiotherapy.     

Spindle and giant cell carcinoma of the bladder. Report of 3 cases

3 cases of spindle and giant cell carcinoma are reported. 2 patients with T3N0M0 and T3N1M0 tumors underwent radical cystectomy. They died 8 and 9 months after cystectomy for local recurrence and tumor metastases. Neither radiotherapy nor chemotherapy were effective in these 2 patients. 1 patient with T1NXM0 disease underwent resection of the tumor through cystotomy. Although she had neither adjuvant chemotherapy nor radiotherapy, she is well without recurrence 6 years after surgery. Early surgical resection of the tumor may be the only currently accepted therapy of spindle and giant cell carcinoma of the bladder.

Abstract：

Objective To investigate the clinical and pathological features of small cell carcinoma of the urinary bladder. Methods The pathological and clinical data of 9 cases of small cell carcinoma were analyzed retrospectively. There were 6 males and 3 females, ages 45 to 79 years (mean age, 62 years). Clinical manifestations of 7 cases included gross hematuria and dysuria, the other 2 cases experienced lower abdominal pain. The mean tumor size was 2.0 cm (ranged, 0.5 to 7.0 cm). Two cases had multiple tumors and 5 cases had single tumors. The growth pattern in 2 cases was diffuse growth in the whole bladder. In 4 cases tumor cells were found in urine cytology. All 9 patients underwent surgical treatment, including TURBt. Four patients were diagnosed as superficial tumors before operation. All the patients underwent regular theprubicine irrigation in the bladder. One case underwent additional intravenous chemotherapy for 3 cycles. Partial cystectomy was performed in 2 cases, with regular theprubicine irrigation in bladder and 1 case underwent intravenous chemotherapy for 2 cycles. Radical cystectomy was performed in 3 cases, with 2 cases undergoing intravenous chemotherapy after operation. Results Pathological findings showed that tumor cells were small and round in shape. These hyperchromatic nuclei showed limited cytoplasm with lack of nesting characters. CgA and NSE were positive in immunohistochemistry. The final diagnosis was small cell carcinoma, with 1 case accompanied with transitional cell carcinoma and 1 case accompanied with prostate cancer. One case showed high preoperative serum calcium (3.15 mmol/L) and low serum phosphate (0.61 mmol/L), which returned to normal 1 month after operation. Four cases who′s bladder was preserved were followed up, 3 cases were alive for 4, 9 and 25 months after operation. The 1 case who underwent intravenous chemotherapy was followed up for 24 months and there was no sign of relapse or metastasis. In all the 3 cases with radical cystectomy, 2 cases died 2 and 28 months postoperativly. Another case with adjuvant chemotherapy was followed up for 24 months without recurrence or metastasis. Conclusions Small cell carcinoma of the urinary bladder is highly malignant with poor prognosis. Radical cystectomy in combination with systemic chemotherapy has better efficacy. Retained bladder surgery with systemic chemotherapy is an alternative choice. The most important factors which influence the prognosis of the tumor are clinical stage and therapeutic methods.     

膀胱非上皮性肿瘤

目的：提高膀胱非上皮性肿瘤的诊治效果。方法：回顾性分析1990／2002年收治的11例膀胱非上皮性肿瘤的临床资料。结果：膀胱平滑肌瘤、血管瘤及副神经节瘤各1例,行膀胱部分切除,术后无复发;膀胱小细胞癌3例,其中1例仅作探查活检术,术后行髂内动脉插管化疗,于术后18月死亡;另外2例作膀胱部分切除术,分别于术后3月和7月死亡;膀胱横纹肉瘤2例,1例仅作根治性膀胱全切 原位回肠膀胱术,于术后6月死亡,另1例行膀胱部分切除术后失访;恶性副神经节瘤1例,行膀胱部分切除术后9年出现广泛转移;肉瘤样癌2例,1例仅作探查活检术,另1例仅作膀胱部分切除术,均于术后6月内死亡。结论：膀胱非上皮性肿瘤少见,良性肿瘤预后好;恶性肿瘤预后差,须行综合治疗,并作密切随访。     

Small cell carcinoma of the urinary bladder treated with chemotherapy and radiotherapy: results in five cases

Small cell carcinoma of the bladder is a rare and highly aggressive tumor. We report our experience with 5 consecutive patients treated with systemic chemotherapy and adjuvant radiotherapy. TNM stages were T2N0M0 (1 patient), T3aN0M0 (3 patients) and T3bN1M0 (1 patient). The chemotherapy protocol was the one used with small cell lung cancer patients at our hospital: six cycles of alternating PE/CAV (PE: cisplatin, etoposide; CAV: cyclophosphamide, doxorubicin, vincristine). Cystoscopy was performed after the third cycle. Four out of 5 patients were free of macroscopic disease. The fifth patient had persistent lesions and was treated by cystectomy. This patient developed a local-regional recurrence 4 months later and died shortly afterwards. Four patients completed the planned six cycles. Cystoscopy with bladder biopsy was then performed on each, and all had complete remission. They were treated with external radiotherapy (45 Gy pelvis, 60 Gy bladder). One patient had invasive bladder recurrence 12 months later and cystectomy was performed. At the last follow-up 42 months later, he was alive and well. The other 3 patients were alive and free of disease 60, 48 and 27 months after diagnosis, respectively. These results are clearly more favorable than previous reports. Cystectomy might, therefore, be unnecessary in some patients.
