Yes, Here are two recent review articles on tumor vaccine development:
http://www.ncbi.nlm.nih.gov/pubmed/22809568
http://www.ncbi.nlm.nih.gov/pubmed/22639169 Its an exciting field. In principle, tumors shouldn't grow in most cases, but the ones that do seem to have an immune evasion program. Its not well understood, but many tumors attract macrophages (as they should) then the macrophages switch to a quiescent phenotype (which they should not). Obviously there are some kind of signaling mechanisms that are akin to Obi Wan waving his hand and saying "These are not the cells you're looking for." The idea behind tumor vaccine is that perhaps its possible to expose immune cells to some component of the tumor (secreted vesicle, cell lysate, etc.) ex vivo, so that the immune cells aren't already compromised by the tumor, and then inject them back into the patient. Some preclinical studies have shown a lot of promise, but I don't know if its been advanced to patent trials anywhere.
