Immunotherapy in Some Types of Tumors
Journal Title: Open Access Journal of Oncology and Medicine - Year 2018, Vol 1, Issue 5
Abstract
Immunotherapy exerts its antitumor action by stimulating the response immune response of patients to cancer, unlike classic treatments, which directly attack the tumor. Previously immunotherapy was limited to patients in whom the conventional treatment, usually with chemotherapy, but currently in patients with some types of tumors, such as melanoma or some lung cancers, is already considered the treatment of first choice. Immunotherapy is able to control some types of malignant tumors prognosis very long, even for several years. Immunotherapy exerts its antitumor action by stimulating the immune response of patients against cancer, unlike classic treatments, which attack directly to the tumor. This implies a series of advantages and characteristics of this novelty strategy. Its main advantage is its ability to control the tumor for very long periods of time in a certain percentage of patients, which varies according to the type of cancer. In some patients with tumors that were previously considered incurable, at this time they are getting very long survivals, even years. Currently, immunotherapy with antibodies that block PD-1 receptors or action on these PD-L1 protein receptors has shown efficacy against a large number of tumors, including among others melanoma, cancers of the lung, kidney, bladder, these treatments are usually administered intravenously and their toxicity is usually lower than conventional treatments, such as chemotherapy.
