Stopped: Per stopping rule if 12 patients underwent immune response analysis after 6 vaccinations and none developed a response, the protocol would stop accrual.
Background: \- Certain types of cancers, including sarcoma and melanoma, have specific antigens (protein molecules) on their surfaces. Research has shown that producing an immune reaction to these antigens may be able to keep tumors from growing by encouraging the immune system to destroy the tumor cells. By creating a vaccine that contains antigens similar to those found on the cancer cells, researchers hope to cause an immune reaction that targets the cancer cells. However, more research is needed to determine the safety and effectiveness of this type of vaccine treatment. Objectives: \- To determine whether a tumor cell vaccine, given to individuals who have had surgery to remove malignant tumors from the chest, can cause an immune reaction that will prevent the tumors from coming back. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with cancer that has spread to the lungs, pleura, or mediastinum, and have recently had surgery to remove tumors in the chest. Design: * Participants will be screened with a physical examination and medical history, as well as blood tests and imaging studies. * Participants will have the option to have leukapheresis to collect white blood cells for studies on how the body is responding to the vaccine. Participants who agree to have this procedure will have it before the start of treatment and after the sixth and eighth vaccines. * Seven days before the first vaccine, participants will receive the chemotherapy drugs celecoxib and cyclophosphamide to take twice a day at home. * Participants will receive the experimental vaccine as an injection in the thigh or arm, and may receive it in two shots depending on how many cells are in each vaccine. Participants will receive a diary to monitor medication doses and side effects, as well as additional cyclophosphamide and celecoxib to take at home as directed by the study. * Participants will have one vaccine every month for 6 months, and will have regular blood tests and imaging studies. After the sixth vaccine, participants who have successfully responded to the treatment will have two additional vaccines given 3 months apart. * After the eighth vaccine, participants will have followup visits every 3 months for 1 year and then every 6 months for up to 4 years....
