They give an interesting description of the "cancer vaccine" used in the study:

The vaccine was made by surgically removing cancerous or myelodysplasic tissue from patients and genetically altering the diseased cells so they would produce a protein called GM-CSF. When these modified cells were injected into patients as a vaccine, the cells began pumping out GM-CSF. Just as a matador's cape provokes the bull to attack, GM-CSF spurred the immune system to attack cancer cells throughout the body.
