Interleukin-2 Combined With Monoclonal Antibody Therapy in Treating Patients With Kidney, Bladder, or Lung Cancer That Has Not Responded to Previous Treatment

RATIONALE: Interleukin-2 may stimulate a person's white blood cells to kill tumor cells. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Interleukin-2 combined with a monoclonal antibody may be an effective treatment for kidney, bladder, or lung cancer. PURPOSE: Phase I trial to study the effectiveness of interleukin-2 combined with a monoclonal antibody in treating patients who have kidney, bladder, or lung cancer that has not responded to previous treatment.
