In recent years, cancer treatment has evolved beyond the traditional methods of surgery, chemotherapy, and radiation. One of the most promising and revolutionary approaches today is immunotherapy—a treatment that harnesses the body’s own immune system to fight cancer. As a trusted cancer specialist in PCMC, Dr. Ashish Pokharkar brings advanced cancer care options to patients, including cutting-edge immunotherapy, which is transforming survival outcomes and offering new hope.
What is Immunotherapy?
Immunotherapy, also known as biologic therapy, is a type of cancer treatment designed to enhance the body’s natural defenses. Unlike chemotherapy, which directly attacks cancer cells but also affects healthy cells, immunotherapy works by stimulating or restoring the immune system’s ability to identify and destroy cancer cells.
The immune system naturally patrols the body, identifying and eliminating foreign invaders such as bacteria, viruses, and abnormal cells. However, cancer cells often develop strategies to evade immune detection. Immunotherapy helps overcome this evasion and reactivates immune responses against cancer.
Types of Immunotherapy
Several types of immunotherapy are currently in use or under research, and each works in a different way:
-
Checkpoint Inhibitors: These drugs remove the “brakes” that prevent immune cells from attacking cancer. Proteins like PD-1, PD-L1, and CTLA-4 are targets of checkpoint inhibitors, and they have shown significant success in treating cancers such as melanoma, lung cancer, and bladder cancer.
-
CAR T-Cell Therapy: This involves collecting a patient’s T-cells, genetically modifying them to better recognize cancer cells, and then infusing them back into the patient. CAR T-cell therapy has shown remarkable results in certain types of blood cancers like leukemia and lymphoma.
-
Monoclonal Antibodies: These lab-made proteins are designed to bind to specific targets on cancer cells. Some antibodies mark cancer cells so the immune system can find and destroy them, while others deliver toxic substances directly to the tumor.
-
Cancer Vaccines: These stimulate the immune system to attack cancer cells, either by preventing the cancer (like HPV vaccines) or by treating existing cancer (therapeutic vaccines).
-
Immune System Modulators: These enhance the overall activity of the immune system rather than targeting a specific part. Examples include cytokines like interleukins and interferons.
Benefits of Immunotherapy
Immunotherapy offers several advantages over traditional treatments:
-
Fewer Side Effects: While not side-effect free, immunotherapy generally spares healthy tissues more effectively than chemotherapy or radiation.
-
Long-lasting Effects: Some patients experience long-term remission even after the treatment ends.
-
Personalized Treatment: Immunotherapy can be tailored based on a patient’s specific cancer type and genetic profile.
Many patients who had limited options in the past are now experiencing renewed hope through immunotherapy. As a dedicated cancer specialist in PCMC, Dr. Ashish Pokharkar incorporates immunotherapy into personalized treatment plans to maximize outcomes and improve quality of life.
Cancers Treated with Immunotherapy
Immunotherapy has shown proven results in treating a variety of cancers, including:
-
Melanoma (skin cancer)
-
Non-small cell lung cancer
-
Kidney cancer
-
Bladder cancer
-
Head and neck cancers
-
Hodgkin lymphoma
-
Some forms of breast and colon cancer
Research is ongoing, and many other cancers are being evaluated in clinical trials to expand the use of immunotherapy.
Challenges and Considerations
Despite its promise, immunotherapy is not suitable for all patients or all cancer types. Some challenges include:
-
Variable Response: Not every patient responds to immunotherapy. Biomarker testing (like PD-L1 expression) is often used to predict response.
-
Side Effects: These can include inflammation of organs (autoimmune reactions), fatigue, skin reactions, or flu-like symptoms.
-
Cost: Immunotherapy can be expensive, although many insurance providers are beginning to cover it.
A skilled cancer specialist evaluates the risks and benefits of immunotherapy in each case to determine its suitability. In PCMC, Dr. Pokharkar uses a thorough diagnostic approach to assess patient eligibility and guide treatment decisions effectively.
The Future of Cancer Treatment
The future of immunotherapy is promising, with ongoing research leading to better drugs, combination therapies, and more precise targeting of cancer cells. Scientists are exploring:
-
Combining immunotherapy with chemotherapy or radiation
-
Using artificial intelligence to predict treatment responses
-
Expanding immunotherapy to pediatric and rare cancers
-
Personalized immunotherapy based on individual tumor genomics
These advancements are expected to make immunotherapy accessible to more patients and increase its effectiveness.
