Melanoma Vaccines: Possible Progress After Years of Frustration?
| The first 150 words of the full text of this article appear below. |
For decades, efforts to create a vaccine against melanoma, the most lethal type of skin cancer, have been exercises in frustration. As crafty as they are lethal, melanoma cells can mount evasive defenses that suppress a vaccine's intended role to shrink tumors. Because of that, just 3%–10% of patients treated with experimental vaccines typically show clinical improvements—and some of these may be spontaneous. But far from conceding defeat, scientists are intensifying their efforts to create better immunotherapies against melanoma, and those under development today show more promise than ever.
In a recent phase II clinical trial, Steven Rosenberg, M.D., Ph.D., chief of the National Cancer Institute's surgery branch, tested a new immunotherapy that shrank tumors in up to 72% of metastatic melanoma patients treated. This is the best "objective" result achieved yet in melanoma immunotherapy, according to Tom Gajewski, M.D., Ph.D., associate professor at the University of Chicago Medical Center.
