The patient's have neuroblastoma that has come back, or not gone away. The cancer is harder to treat now. The investigators would like the patient's to be in this research study to determine the safety and dosage of special cells that may make the patient's own immune system fight the cancer. To do this the investigators will put two special genes into neuroblastoma cancer cells that have been grown in the lab. The genes put in make the cancer cells produce lymphotactin, a natural substance that attracts immune system cells to the cancer, and IL-2 a natural substance that may help the immune system kill cancer cells. Some of these cells will then be put into the patient's body. Studies of cancers in animals and in cancer cells that are grown in laboratories suggest that substances like lymphotactin and IL-2 do help the body kill cancer cells. A treatment similar to this has been used in twelve children previously and similar treatments are being used in adults with other cancers. This is a research study. The investigators do not know the best amount of special cells to use, so different children will get different numbers of cells.
