Small-cell carcinoma of the urinary bladder: 10-year experience.
OBJECTIVE
Small-cell carcinoma of the urinary bladder is rarely encountered in clinical practice. We report on our clinical experience with affected patients presenting to our institution from 1986 to 1996.


METHODS
We retrospectively analysed 14 pathologically confirmed cases, specifically looking at stage, presenting features, treatment and overall survival. The median age at presentation was 74 years (range 54-91 years).


RESULTS
Ten patients presented with stage III disease, and four patients with stage IV disease (1 = nodal, 3 = distant metastases). Four patients were treated with radical radiotherapy (one patient receiving neoadjuvant chemotherapy) and two underwent a radical cystoprostatectomy. Five patients received palliative bladder radiotherapy and three were too frail for treatment at presentation. The overall median survival was 5 months. Patients receiving radical treatment had a median overall survival of 21 months, with only one long-term survivor.


CONCLUSIONS
This highly aggressive tumour tends to affect an elderly population who are generally frail and have significant comorbidity. Many are unfit for radical treatment. In patients with disease confined to the pelvis who are able to tolerate radical intervention, the results of local therapy alone are poor. It therefore remains incumbent on treating clinicians to explore means of improving these results. Initial chemotherapy analogous to small-cell lung cancer may offer a durable response with a better chance for long-term survival.
