Do you know that you can train your immune system to treat cancer cells with the help of Immunotherapy in India? Yes, you read it correctly. Generally, any treatment of cancers is focused on removing fast-growing cancerous cells and tissues from the body. However, if we can make the immune system strong or train the immune system to fight cancerous cells and tissues, the body will learn to fight on its own. It is the revolutionary and best cancer treatment with profound potential. Well, many researchers are continuously evolving this therapy for consistent results and broader applications.
This article will encompass the types and processes of different kinds of immunotherapies in India. So, without any further ado, let’s get to begin.
Brief History of Immunotherapy in India
William B Coley from New York technically laid the foundation of immunotherapy in 1891 and was invented to help patients with cancer whose tumors could not be removed surgically. He injected a mixture of beef broth and Streptococcus bacteria into the arm of an Italian cancer patient with an inoperable neck tumor. At first, the man got extremely sick with a fever and was accompanied by vomiting and chills. One month later, his tumor shrunk considerably. Then, William Coley replicated this process on thousands of other cancer patients, but eventually, the FDA stopped him.
For decades after Coley’s initial successes in the treatment of cancer patients, it triggered the curiosity of the medical community, especially oncologists, to develop immunotherapy. They developed apoptosis-based radiation and chemotherapy treatments, eventually becoming popular. But the concept of re-generating the patient’s immune system keeps evolving since it is the most targeted treatment and causes fewer side effects than the other treatments. Thus, in the last few years, there has been exceptional growth in immunotherapy in India.
Types of Immunotherapies and their Processes
- Monoclonal Antibodies
Our immune system makes specific proteins called antibodies. They find and stick to other proteins called antigens in cancer cells. Then they recruit other parts of your immune system to destroy the cancer cells. Well, researchers can make antibodies in the lab, which are known as monoclonal antibodies, and they work in different ways, such as-
- Naked monoclonal antibodies
These are the most common types that are used in cancer treatment. As the name implies, they are not attached to anything and help boost your immune response against cancer or block the antigens that help the cancer cells grow and spread in the body.
- Conjugated monoclonal antibodies
In this, a chemotherapy drug or radioactive particle is attached to them, and the antibodies are directly connected to the cancer cells. This reduces side effects and enables chemotherapy and other radiation treatment to work better.
- Bispecific monoclonal antibodies
These attach to both proteins at once. Some attach to both cancer cells and immune cells, which help the immune system attack cancer.
2. Non-specific Immunotherapies
This type of immunotherapy is usually given in chorus with other traditional treatments like chemotherapy. It is done either by using Interferons which are prepared in the laboratory and slow down the growth of cancer cells, or by using Interleukins, which destroy the cancer cells.
3. Cancer Vaccines
Cancer vaccines are made from dead cancer cells, proteins or proteins from cancer cells or immune system cells. There are four vaccines approved to prevent cancer cells named as-
- Cervarix, Gardasil and Gardasil-9 are linked to cancers of the throat, cervix, vagina, vulva, anus and penis.
- Hepatitis B (HBV) vaccine (HEPLISAV-B), protects against HBV infections that can cause liver cancers.
Other than this, the three vaccines that are approved by FDA are-
- Sipuleucel-T (Provenge)- It treats advanced prostate cancer when hormone therapy doesn’t work.
- Talimogene laherparepvec (T-VEC)- It is used for treating melanoma skin cancer.
- Bacillus Calmette-Guérin, or BCG- This is used for treating early-stage bladder cancer.
Scientists and researchers are studies for other cancer vaccines too in clinical trials.
