Abstract
Since the invention of Coley's toxin by William Coley in early 1900s, the path for cancer immunotherapy has been a convoluted one. Although still not considered standard of care, with the FDA approval of trastuzumab, Provenge and ipilimumab, the medical and scientific community has started to embrace the possibility that immunotherapy could be a new hope for cancer patients with otherwise untreatable metastatic diseases. This review aims to summarize the development of some major strategies in cancer immunotherapy, from the earliest peptide vaccine and transfer of tumor specific antibodies/T cells to the more recent dendritic cell (DC) vaccines, whole cell tumor vaccines, and checkpoint blockade therapy. Discussion of some major milestones and obstacles in the shaping of the field and the future perspectives is included. Photoimmunotherapy is also reviewed as an example of emerging new therapies combining phototherapy and immunotherapy.
