【Abstract】 Objective To improve the understanding of small cell carcinoma of the urinary bladder. Methods The pathological and clinical data of 6 small cell carcinoma cases (4 men and 6 women, mean age of 51 years) were analyzed.Of them 2 cases had components of transitional cell carcinoma or adenocarcinoma.Two cases underwent partial cystectomy,and 4 cases,cystectomy.After operation,5 of them underwent 2～6 courses of chemotherapy. Results All the 6 cases were followed-up for 12～60 months,and they all died of tumor relapse.Their average survival time was 28 months. Conclusions Small cell carcinoma of urinary bladder accounts for 0.44% of the primary malignant tumor of urinary bladder.It has high malignancy and easily metastasizes to lymph nodes,liver and bones,thus the prognosis is bad.Radical cystectomy in combination with systemic chemotherapy has better efficacy.更多还原
