Summary
Brief summary (as posted)
RATIONALE: Immunotoxins can locate tumor cells and kill them without harming normal cells. Immunotoxin therapy may be effective in treating advanced solid tumors. PURPOSE: This phase I trial is studying the side effects and best dose of immunotoxin therapy in treating patients with recurrent unresectable advanced solid tumors.
