[History of and novel developments in cancer immunotherapy - introduction to the special issue]
1Dept. of Clinical Oncology, Kawasaki Medical School, Japan.
Over the last 50 years, development in the field of cancer immunotherapy has been fluctuating, ranging from exciting expectations to disappointing clinical outcomes. Now, the time has come again, for cancer immunotherapy. Since 2010, new immunotherapeutics have been approved one after another in the United States of America and other countries. Thus, immunotherapy has definitely been recognized as the fourth therapy for cancer after surgery, radiotherapy, and chemotherapy. Under this establishment, there has been progress not only in the fundamental understanding of the immune system but also in the design of scientific clinical trials, in which delayed-type tumor responses and survival benefits with less tumor shrinkage are used as indicators. The next 3 papers provide exciting insights on novel cancer immunotherapy as an innovative treatment modality for cancer.

Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
