The Role of Immunotherapy in Modern Oncology

Introduction

Cancer treatment has come a long way—from the use of surgery and chemotherapy to the introduction of radiation and targeted therapies. But perhaps the most groundbreaking advancement in recent years has been immunotherapy, a treatment that empowers the body’s own immune system to fight cancer.

This innovative approach is offering hope to millions of patients and is being hailed as the future of cancer care. According to Dr. Sumant Gupta, one of the best Medical oncologists in Faridabad and Senior Consultant & Head – Medical Oncology, Hematology & BMT at Metro Cancer Institute, Faridabad, “Immunotherapy has revolutionized how we think about cancer treatment—it’s not just about killing cancer cells, it’s about helping the body heal itself.”

What is Immunotherapy?

Immunotherapy is a type of biological therapy that uses the power of the body’s own immune system to detect, target, and eliminate cancer cells. Unlike traditional treatments that attack both cancerous and healthy cells, immunotherapy aims to enhance the body’s natural defense mechanisms with greater precision.

Types of Immunotherapy in Oncology

  1. Checkpoint Inhibitors
    These block immune checkpoints—proteins that keep immune responses in check—allowing T-cells to attack cancer more aggressively.

  2. CAR-T Cell Therapy (Chimeric Antigen Receptor T-cell Therapy)
    T-cells are collected from the patient, modified in a lab to better recognize cancer cells, and then reinfused into the patient.

  3. Cancer Vaccines
    Designed to initiate an immune response against cancer-specific antigens.

  4. Cytokine Therapy
    Uses proteins such as interleukins and interferons to boost immune cell growth and response.

  5. Monoclonal Antibodies
    Laboratory-made proteins that can bind to cancer cells and mark them for destruction by the immune system.

How Does Immunotherapy Work?

Immunotherapy trains your immune system to:

  • Recognize cancer cells as threats.

  • Enhance immune cell strength to attack tumors.

  • Remember cancer so it can prevent recurrence.

Dr. Sumant Gupta explains,

“Think of it like giving your immune system a high-tech weapon. It not only fights but also learns and adapts, which is crucial in cancers known for recurrence or metastasis.”

Cancers Commonly Treated with Immunotherapy

Immunotherapy has shown promising results in treating several types of cancers, including:

  • Lung cancer

  • Melanoma

  • Kidney cancer

  • Head and neck cancers

  • Bladder cancer

  • Liver cancer

  • Blood cancers (like lymphoma and leukemia)

Research is ongoing to expand its effectiveness in breast, colon, and ovarian cancers.

Benefits of Immunotherapy

✅ Fewer Side Effects:
Targets cancer cells more specifically than chemotherapy or radiation.

✅ Long-Lasting Remission:
Some patients achieve long-term remission even after stopping treatment.

✅ Boosts Natural Defenses:
It activates immune memory to prevent recurrence.

✅ Effective in Late-Stage Cancers:
Shows success even when other treatments fail.

Challenges of Immunotherapy

Despite its promise, immunotherapy isn’t a one-size-fits-all solution.

  • Not effective for all cancers or patients

  • Can cause autoimmune-like side effects (e.g., inflammation)

  • High cost and accessibility can be barriers in India

Dr. Sumant Gupta emphasizes the importance of individualized treatment planning,

“Every cancer is different. At Metro Cancer Institute, we perform detailed molecular and genetic testing before recommending immunotherapy.”
