Understand Immunotherapy for Cancer Treatments

Immunotherapy is changing the way doctors approach cancer care, and Dr. Murali Subramanian, DM Medical Oncology, explains it as a treatment designed to strengthen the body’s own immune system to fight cancer cells. While chemotherapy, targeted therapies, and other standard methods help reduce the cancer burden, the host immune system ultimately plays a key role in keeping the disease under control for longer durations. Cancer cells are clever at escaping immune surveillance, and this is where immunotherapy for cancer comes in by helping the immune system recognise and attack them more effectively. For those wondering what is immunotherapy, it is a treatment strategy where special medicines, often monoclonal antibodies, are administered through intravenous infusion on a fixed schedule, such as weekly, once in 15 days, or once in 21 days, depending on the type of cancer and treatment plan.

Understanding Immunotherapy: The Future of Cancer Treatment

Immunotherapy has emerged as one of the most innovative breakthroughs in modern oncology. Unlike traditional treatments that attack both healthy and cancerous cells, immunotherapy empowers the body’s own immune system to identify and destroy cancer cells more precisely. This approach is transforming the way doctors treat complex cancers and improving survival outcomes for many patients.

Types of Immunotherapy Treatments

There are several types of immunotherapy available today, each designed to strengthen the body’s natural defence mechanisms against cancer.

One of the most significant advancements is checkpoint inhibitor cancer therapy, which blocks the proteins cancer cells use to evade detection by immune cells. By removing these “checkpoints,” the immune system can recognise and attack the tumour effectively.

Another cutting-edge approach is CAR T cell therapy in India, where a patient’s T cells are genetically re-engineered in a laboratory to target cancer cells with precision. This form of treatment has shown remarkable results, particularly for blood-related cancers such as leukaemia and lymphoma.

In addition, doctors often conduct PD-L1 expression or similar molecular tests on tumour samples to determine if a patient is likely to benefit from immunotherapy. Personalised testing ensures that only the most effective treatment strategies are chosen for each individual.

Immunotherapy vs Chemotherapy: Key Differences

When comparing immunotherapy vs chemotherapy, it becomes evident that these treatments work in completely different ways. Chemotherapy kills rapidly dividing cells, including some healthy ones, which leads to well-known side effects such as nausea, fatigue, hair loss, and diarrhoea.

Immunotherapy, on the other hand, does not directly attack cancer cells; instead, it activates the immune system to do so. Although it can cause immune-related side effects, they are generally milder and easier to manage than those seen with chemotherapy. This often makes immunotherapy a preferred option for patients who cannot tolerate intensive chemotherapy.

Immunotherapy Success in Different Cancer Types

Immunotherapy for lung cancer has shown exceptional results in recent years, offering new hope to patients who previously had limited treatment choices. Similarly, it has proven effective in melanoma (skin cancer), kidney cancer, bladder cancer, and colorectal cancer.

With India rapidly adopting advanced oncology treatments, immunotherapy is becoming an integral part of the country’s cancer care landscape. Ongoing research and clinical trials continue to expand its use, allowing more patients to access this life-changing therapy.

People Also Ask (FAQs)

1. What is checkpoint inhibitor cancer therapy?
Checkpoint inhibitors block specific proteins that prevent the immune system from recognising and attacking cancer cells. They are among the most effective forms of immunotherapy currently in use.

2. How is CAR T cell therapy in India different from traditional treatments?
CAR T cell therapy modifies a patient’s immune cells to target and destroy cancer cells directly. Unlike chemotherapy, it focuses only on diseased cells, minimising harm to healthy tissues.

3. Is immunotherapy better than chemotherapy for all cancers?
Not necessarily. The choice depends on the type and stage of cancer, patient health, and molecular testing results. Some cancers respond best to immunotherapy, while others still rely on chemotherapy or combination approaches.

Conclusion 

Immunotherapy represents one of the most promising advancements in Cancer Treatment, offering patients a better quality of life and improved outcomes compared to traditional options. With experts like Dr. Murali Subramanian leading the way in adopting and explaining these therapies, patients in India now have access to cutting-edge solutions like checkpoint inhibitors and CAR T cell therapy India. As the field continues to expand, immunotherapy will remain a cornerstone of the future of cancer care, offering renewed hope for patients and families alike.
