Immunotherapy has revolutionized cancer treatment by harnessing the power of the immune system to fight cancer. Unlike traditional chemotherapy that directly kills cancer cells, immunotherapy helps your immune system recognize and destroy cancer more effectively.
**Types of Immunotherapy**
Checkpoint Inhibitors - Block proteins that prevent immune cells from attacking cancer (e.g., Keytruda, OPDIVO, Tecentriq)
Monoclonal Antibodies - Target specific proteins on cancer cells (e.g., trastuzumab, rituximab)
Antibody-Drug Conjugates - Deliver chemotherapy directly to cancer cells (e.g., ADCETRIS, Enhertu)
CAR T-Cell Therapy - Genetically modified immune cells that target cancer
Cancer Vaccines - Stimulate immune response against cancer cells
**How Immunotherapy Works**
Your immune system normally identifies and destroys abnormal cells. Cancer cells develop ways to hide from or suppress the immune system. Immunotherapy removes these disguises or boosts immune function, enabling your body to fight cancer naturally.
**Cancers Treated with Immunotherapy**
Melanoma, Lung cancer (NSCLC, SCLC), Kidney cancer, Bladder cancer, Head and neck cancers, Lymphomas (Hodgkin and non-Hodgkin), Breast cancer (triple-negative, HER2+), Liver cancer, Gastric/esophageal cancer, Colorectal cancer (MSI-H), and many others.
**Benefits of Immunotherapy**
Durable responses - Some patients achieve long-lasting remissions. Fewer side effects than chemotherapy in many cases. Treats multiple cancer types. Can work after other treatments fail. Potential for combination with other therapies.
**Common Side Effects**
Immune-related adverse events can include fatigue, skin reactions, diarrhea/colitis, pneumonitis, hepatitis, endocrine disorders, and arthritis/joint pain. Most are manageable with proper monitoring and early intervention.
**Who Is a Good Candidate?**
Biomarkers help predict response: PD-L1 expression (for checkpoint inhibitors), tumor mutational burden (TMB), microsatellite instability (MSI-H/dMMR), HER2 status (for targeted antibodies), and specific genetic mutations.
**Treatment Process**
Biomarker testing first, then intravenous infusion (typically 30-90 minutes), treatment schedules vary (every 2-6 weeks), duration ranges from months to 2+ years, and regular monitoring for side effects.
**Cost and Access**
Immunotherapies are expensive but most insurance plans cover FDA-approved indications. Patient assistance programs available from manufacturers. Clinical trials provide access to newer therapies.
**Questions to Ask Your Doctor**
Which immunotherapy is right for my cancer type? What biomarker tests do I need? What are the expected benefits and risks? How will treatment affect my quality of life? Are there clinical trials available?
