      New clinical trial trains body to fight melanoma

      COLUMBIA (WACH) --- Todd Greenlee has been in and out of the hospital since he was diagnosed with stage-4 melanoma last year.

      â??I had a large, almost like tennis ball sized lump underneath my left arm,â?? says Todd Greenlee.

      Surgeons removed the lump, but the cancer came back and spread. With no other options, Doctors encouraged Todd to enroll in a new clinical trial.

      Dr. Michael Nishimura says t-cells are removed from a patient and genetically modified. â??We actually engineer the cells to make them work better, so that they can target your cancer cells,â?? says Dr. Michael Nishimura.

      To make room for the new army of t-cells, high doses of chemo are used to wipe out any other t-cells in the body. Next, the new t-cells recognize the cancerous cells and kill them. A fight Greenlee plans to win one step at a time.

      â??On the CT scans they've seen some spots actually gone. They've also seen spots that have diminished in size,â?? says Greenlee.

      This is not Greenleeâ??s first battle with cancer. Heâ??s survived two brain tumors.

      The trial is currently recruiting at Loyola University Medical Center in Chicago and is open to patients with metastatic melanoma who have no other options.
