Summary:

      RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different
      ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and
      help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the
      growth of tumor cells by blocking blood flow to the tumor.

      PURPOSE: This phase II trial is studying how well bevacizumab works in treating patients with
      angiosarcoma.
