Our body’s immune system protects us from unwanted invaders like bacteria, viruses, or tumor cells. But, they may not defend our body from cancer cells. In this case, Immunotherapy for lung cancer stops cancer cells from hurting the immune system and boosts the fight against it.
Lung cancer affects approx 2.1 million people worldwide, with an estimated 1.7 million deaths. Immunotherapy is a new treatment option to benefit people with some kinds of lung cancer. It allows the body’s immune system to detect and attack cancer cells. Let’s know everything about this effective cancer treatment.
What Is Immunotherapy?
We all know that the immune system protects our body from foreign agents. It attacks bacteria and viruses, keeping our bodies safe. However, cancer cell includes normal human organ cells, and they both have familiar features to some extent. Due to this, the cancer cells become successful in avoiding the immune system.
Also, as soon as the cells become cancerous, they acquire new features. Now, these new cells feature as foreign agents destroying our immune system.
Immunotherapy for lung cancer involves using drugs to make the immune system detect cancer cells and destroy them. Thus, it allows treating cancer cells with the help of the body’s immune system.
Sometimes, Immunotherapy for cancer cure is also called immuno-oncology. Doctors usually advise people to get Immunotherapy for lung cancer. It is also advisable when other treatment options do not work.
What Are the Various Types of Immunotherapy For Lung Cancer?
Immunotherapy can be helpful for people who have lung cancer. Below are its various types for treating lung cancer patients.
Immune Checkpoint Inhibitors
The immune checkpoint inhibitors are the immune cell molecules that respond to the immune system. These molecules use the immune system to define our body’s normal and abnormal conditions. They detect the invader and attack them to protect our bodies.
However, the cancer cell tricks our body’s immune system by showing some checkpoints. It helps cancer protect itself from getting attacked by the body’s immune system.
There are many approved drugs for lung cancer treatment that target immune system checkpoints. These drugs have similar side effects as chemotherapy, such as skin rash, fatigue, itching, nausea, etc.
However, these drugs’ side effects are less than chemotherapy’s. In this case, Immunotherapy helps the immune system to detect and stimulate them to attack cancer cells.
You must have heard of vaccines that help keep away various diseases. Several helpful vaccines are available worldwide, including the therapeutic vaccine. It is a helpful vaccine that improves the immune system and allows it to destroy any current cancer. This type of vaccine targets proteins available in the cancer cells. These proteins are not present in other normal cells or may only be found in very few of them.
Before giving a vaccine to a person, vital medicine is given to dampen the immune cells that help cancer grow. These vaccines are customizable according to one’s cancer to the target protein. But these cancer vaccines have not received approval for lung cancer treatment by the FDA; they are still in clinical trials.
Adoptive T-Cell Therapy
This therapy removes T-cells from the body and alters them in a lab. These cells are a type of immune system white blood cells. Thus, the immune system attacks specific cancer cells better.
After modification of the T-cells, these are put back in our bodies to fight cancer. Removing the T-cells from the body is done using a method, Plasmapheresis. It allows for blood filtering and identifying certain kinds of blood cells.
The other process of doing it is by getting part of the tumor removed and T-cells separated from the body. Researchers are still studying this type of therapy, and the FDA does not approve it to cure lung cancer.
Who Are Suitable For Immunotherapy Treatment?
Previously, chemotherapy, surgery, and radiation were some treatment options for lung cancer patients. But, when these options proved weak, researchers found a new treatment called Immunotherapy.
It includes many FDA-approved drugs for lung cancer that are advisable to the patient at the advanced stage. But, most people at their initial stage receive this treatment.
Sometimes, chemotherapy or two distinct kinds of Immunotherapy are given to the patient. Each drug has its specification that must be given according to the lung cancer type, past treatment history, and current general health.
How Immunotherapy Differs From Other Lung Cancer Treatments?
Chemotherapy treatment uses chemicals to destroy cancer cells. It can affect your body’s healthy normal cells and shows many side effects, including fatigue, nausea, hair loss, reduction in the count of white blood cells, and many more.
Immunotherapy greatly differs from other lung cancer treatment options like traditional chemotherapy, radiation, and targeted therapy.
Unlike other therapies, radiation therapy involves the usage of solid X-rays to destroy cancer cells. This therapy focuses on attacking specific targets in tumor cells that help grow it without any control. Targeted therapy deals with mutations in some kinds of lung cancer tumors.
However, Immunotherapy focuses on targeting the communication between the body’s immune system and the tumor. It helps the immune system fight against cancer and destroys its cells.
Immunotherapy for lung cancer treatment is a new as well as a unique type of treatment option. It helps treat patients who are suffering from lung cancer. The process involves drugs that make the body’s immune system effective in detecting and killing cancer. One can take this treatment at any stage or other treatment options.
This therapy is different from other lung cancer treatment options. As it is a new treatment, care is essential while taking this therapy. A patient can take various types of Immunotherapy according to their cancer problem, symptoms, and health issues.
