Immunotherapy is a groundbreaking cancer treatment that harnesses the body's own immune system to fight cancer cells. Unlike traditional treatments like chemotherapy and radiation, immunotherapy enhances the immune system's ability to recognize and eliminate cancerous cells, offering a more targeted approach. In this article, we explore how immunotherapy works, the types of cancer it treats, and the top hospitals offering this treatment in India.
What is Immunotherapy?
Immunotherapy is a type of cancer treatment that boosts the body's natural defenses to fight cancer. It uses substances made by the body or in a laboratory to improve the immune system’s response against cancer cells. Unlike chemotherapy, which directly kills cancer cells, immunotherapy helps the immune system to better recognize and destroy them.
How Does Immunotherapy Work?
Immunotherapy works by enhancing the immune system’s ability to detect and attack cancer cells. Cancer cells can evade the immune system by disguising themselves as normal cells, but immunotherapy helps the immune system to recognize and destroy them. There are several types of immunotherapy, including immune checkpoint inhibitors, CAR T-cell therapy, and cancer vaccines.
Types of Immunotherapy
There are several forms of immunotherapy used to treat cancer:
- Immune Checkpoint Inhibitors: These drugs block the proteins that prevent immune cells from attacking cancer cells.
- Cytokines: These proteins help regulate and boost the immune system's response to cancer.
- Cancer Vaccines: Vaccines help the immune system recognize cancer cells and destroy them.
- CAR T-cell Therapy: This therapy involves modifying a patient’s T-cells to better recognize and kill cancer cells.
Which Cancers Can Be Treated with Immunotherapy?
Immunotherapy has been shown to be effective in treating several types of cancer, especially those that have not responded well to traditional treatments. These cancers include:
- Melanoma: One of the first cancers to show significant response to immunotherapy.
- Lung Cancer: Non-small cell lung cancer (NSCLC) patients can benefit from immune checkpoint inhibitors.
- Bladder Cancer: Immunotherapy is increasingly used for advanced or metastatic bladder cancer.
- Lymphoma: Certain types of lymphoma, such as Hodgkin’s lymphoma, respond well to immunotherapy.
1. How does Immunotherapy work for liver cancer treatment
Immunotherapy for liver cancer stimulates the body's immune system to attack and destroy cancer cells. It works by enhancing or restoring the immune system's ability to fight cancer, using drugs like checkpoint inhibitors to block proteins that prevent immune cells from attacking the tumor.
For liver cancer, immunotherapy is used in cases of advanced disease, improving the body's ability to target and eliminate cancerous cells, and can be combined with other treatments like targeted therapy or chemotherapy.
Common side effects include fatigue, fever, and skin reactions, though it has shown potential in extending survival for liver cancer patients.
Benefits of Immunotherapy for Cancer Treatment
Immunotherapy offers several advantages over traditional cancer treatments:
- Targeted Approach: It targets cancer cells more precisely while sparing healthy cells.
- Long-Lasting Effects: The immune system can remember cancer cells, offering long-term protection against recurrence.
- Fewer Side Effects: Immunotherapy generally has fewer side effects compared to chemotherapy and radiation.
Side Effects of Immunotherapy
Although immunotherapy tends to cause fewer side effects than chemotherapy, it can still cause reactions. Common side effects include:
- Fatigue
- Skin rashes
- Flu-like symptoms
- Diarrhea
- Low blood pressure
Severe side effects, such as lung inflammation or liver problems, are rare but can occur.
Immunotherapy vs. Chemotherapy: What’s the Difference?
The main difference between immunotherapy and chemotherapy is how they work. Chemotherapy kills both cancerous and healthy cells by targeting all rapidly dividing cells. In contrast, immunotherapy helps the body’s immune system target only cancer cells, which generally results in fewer side effects and a longer-lasting immune response.
Eligibility for Immunotherapy
Not all patients are eligible for immunotherapy. This treatment is typically recommended for patients with specific types of cancer or those whose cancer has returned after other treatments. Genetic testing and biomarker analysis are often used to determine if a patient is a good candidate for immunotherapy.
How to Prepare for Immunotherapy in India
Before beginning immunotherapy, patients must undergo a thorough evaluation, including blood tests and imaging, to assess the extent of the cancer. Genetic testing may also be necessary to identify specific mutations or biomarkers that make the cancer susceptible to immunotherapy.
Top Hospitals Offering Immunotherapy in India
Several world-class hospitals in India offer immunotherapy as part of their cancer treatment programs. Some of the leading hospitals include Tata Memorial Hospital in Mumbai, which is renowned for advanced cancer care. AIIMS in Delhi and Apollo Cancer Centres in multiple cities are also known for providing cutting-edge immunotherapy treatments for various cancers.
Cost of Immunotherapy in India
The cost of immunotherapy in India can range from ₹2 lakh to ₹10 lakh per treatment cycle, depending on the type of cancer, the specific drug used, and the duration of treatment. Although costly, immunotherapy in India is still more affordable compared to many Western countries.
Success Rates of Immunotherapy
Immunotherapy has shown remarkable success in treating certain types of cancers, especially melanoma and non-small cell lung cancer (NSCLC). For these cancers, immunotherapy has improved survival rates and overall outcomes, particularly in patients who did not respond to other treatments. The success rate of immunotherapy depends on several factors, including the type of cancer and its genetic profile.
Combining Immunotherapy with Other Treatments
Immunotherapy can be used in combination with other treatments, such as chemotherapy, radiation, or targeted therapy, to improve outcomes. Combining therapies helps to attack cancer cells in multiple ways, increasing the chances of a successful outcome. For example, chemotherapy may weaken cancer cells, making them more vulnerable to attack by the immune system.
Future of Immunotherapy in Cancer Treatment
Immunotherapy is evolving rapidly, with ongoing research aimed at expanding its use to more types of cancer. Scientists are exploring how to improve immune checkpoint inhibitors and CAR T-cell therapy to make them more effective against a broader range of cancers. The future of immunotherapy looks promising, with new treatments and combinations being developed to enhance its effectiveness.
