Immunotherapy is also known as biotherapy. It is
a treatment that uses certain parts of the immune system to fight diseases such
as cancer through stimulating your own immune system and giving you immune
system components.
Cancer immunotherapy is an important phenomenon
to enhance the immune system to fight against cancer. The main premise is
stimulating the immune system to attack the malignant tumour cells that are
responsible for the disease. In late 1800s, Dr William Coley first noted that
getting an infection after surgery seemed to help some cancer patients. He used
Coley toxins for the treatment of those cancer patients who infected with
certain kinds of bacteria.
The main types of immunotherapy involve
monoclonal antibody, cancer vaccines and non-specific immune therapy.
Monoclonal antibody has subtypes, including naked and conjugated, in which
naked monoclonal antibody has further subtypes including radiolabelled,
chemolabelled and immunotoxin. Alemtuzamab is naked approved for chronic lymphocytic
leukemia treatment, Ibritumomab is radiolabeblled approved for treatment of
non-Hodgkin lymphoma, and Brentuximabvedotin is chemolabelled approved for
treatment of Hodgkin lymphoma and anaplastic large cell lymphoma. Cancer
vaccines involving Dendritic cell vaccines (Special immune cells in the body
that help the immune system recognize cancer cells), Tumour cell vaccines (Made
from actual cancer cells that have been removed during surgery), DNA vaccines
(Vectors can be given bits of DNA which is code for protein antigens. At the
same time the vectors are then injected into the body, with cells that DNA
might be taken up and can instruct them to make specific antigens) and Antigen
vaccines (These vaccines boost the immune system by using only one antigen
rather than whole tumour cells). Non specific immune therapy has also subtypes,
including cytokines and interleukin.
Later research in monoclonal antibodies by United
States doctors from the Clinical Research Division led by Cassian Yee by Fred
Hutchinson Cancer Research Centre in June 2008 treated a skin cancer patient by
using immune cells cloned from his own immune system which were then
re-injected into him. In topical immunotherapy, Imiquimod that is immune
enhancement cream, which is an interferon producer causing the patient’s own
killer T cells to destroy basal cell and squamous cell carcinoma. In natural
products, mushrooms like Agaricussubrufescens that is able to stimulate the
immune system.
GAP has the advanced technology and an expert
team for immune therapy, which helps the cancer patients in planning their
treatment strategy.
