Abstract:
Objective To study the clinical features,diagnosis and management of small cell carcinoma of the bladder (SCCB).Method The clinical data of 18 cases of patients with small cell carcinoma of the bladder were analyzed retrospectively and the literature were reviewed.There were 16 males and 2 females,ages 54 to 81 years (median age,61 years).Clinical manifestations included gross hematuria in 11 cases,urgency in 2 cases,dysuria in 2 cases and postoperative review after TURBT of bladder urothelial carcinoma in 3 cases.The median tumor size was 3.35cm (ranged,1.0 to 6.0 cm).2 cases underwent TURBT and intravesical chemotherapy regularly were followed after surgery.3 cases underwent partial cystectomy,intravenous chemotherapy combined with radiotherapy was followed in one case,the other 2 cases refused the following therapy.13 cases underwent radical cystectomy,intravenous chemotherapy was followed in 2 cases,pelvic radiotherapy was followed in 2 csaes and intravenous chemotherapy combined with radiotherapy was followed in 2 cases,the other 7 cases refused the following therapy.Results 11 cases were pure SCCB,7 cases were mixed SCCB,all with urothelial carcinoma.T1N0M0 in 3 cases,T2N0.1M0 in 4 cases,and T3N0-2M0 in 11 cases.The duration of follow-up was from 5 to 35 months after surgery.9 cases died of tumor metastasis,9 cases are still alive,except 1 case with lymph node metastasis,the other 7 cases are free of tumor recurrence or metastasis.Conclusions SCCB is rare,with high malignant degree and poor prognosis.The prognosis of the pure SCCB may be worse than the mixed SCCB.The diagnosis depends on pathology examination.Radical cystectomy is the main treatment method,the strategy of bladder-preserving may be an attempt for proper SCCB patients.Adjuvant therapy plus surgery may be better.
