Small cell carcinoma of the bladder
- Type of neuroendocrine histology
- Should be considered and treated as metastatic disease, even if there is no radiologic evidence of disease outside the bladder
- In general, primary small cell carcinoma of the bladder is very chemosensitive
- Primary mode of therapy is chemoradiation therapy; chemotherapy and radical cystectomy is an option with similar survival (5-year CSS 16% chemoradiation vs. 18% chemotherapy and radical cystectomy)
- Primary method to improve survival will be more effective systemic therapy
Signet ring cell carcinomas
- Usually high-grade, high-stage tumors at presentation
- Poor prognosis
Sarcoma
- Subclassification of sarcoma is based on histologic variations, depending on the specific malignant cell type
- Leiomyosarcoma is the most common histologic subtype, followed by rhabdomyosarcoma and then, rarely, angiosarcoma, osteosarcoma, and carcinosarcoma
