Angiosarcoma of bladder: long-term survival after multimodal therapy.

Angiosarcoma of the bladder is extremely rare and carries a dismal prognosis because of the uniformly high-grade and aggressive tumor biology of the neoplasm. We report the long-term disease-free survival of 1 patient, treated with multimodal therapy, whom we have previously reported on. Six years after the initial presentation, the patient died, and the postmortem analysis revealed no evidence of residual disease. Our case represents the longest reported survival of a patient with angiosarcoma of the bladder.
