What is Immunotherapy?

Immunotherapy is a type of treatment that enhances or modifies the body’s immune system to fight diseases such as cancer, autoimmune disorders, and chronic infections. It works by boosting the natural defenses of the immune system, either by stimulating it to work harder or by providing it with additional components like antibodies.

Procedure Classification

Therapeutic Procedure – Immunotherapy is a therapeutic treatment designed to boost or regulate the immune system for the management of diseases such as cancer, allergies, and autoimmune conditions.

Immunotherapy Statistics

• Immunotherapy is increasingly used in cancer treatment. In the UK, around 40% of cancer patients receive some form of immunotherapy.
• Checkpoint inhibitors and monoclonal antibodies are among the most common forms of immunotherapy.
• The global immunotherapy market is projected to grow significantly, reflecting its importance in modern medicine.

Types of Immunotherapy

1. Monoclonal Antibodies: Target specific proteins on cancer cells or immune cells.
2. Checkpoint Inhibitors: Help the immune system recognize and attack cancer cells.
3. Cancer Vaccines: Boost the body’s response to cancer-specific antigens.
4. Adoptive Cell Therapy: Uses modified immune cells, such as CAR T-cells, to attack cancer.
5. Cytokines: Proteins like interferons and interleukins that help regulate immune responses.
6. Allergy Immunotherapy: Reduces sensitivity to allergens through gradual exposure.

Anatomy and Physiology

Immunotherapy interacts with the immune system and affects various organs and tissues:

• Lymphatic System: Including lymph nodes and lymph vessels, it plays a crucial role in immune response.
• Bone Marrow: Produces immune cells such as lymphocytes.
• Thymus: Where T-cells mature and learn to recognize foreign invaders.
• Spleen: Helps filter blood and manage the immune response.
• Targeted Organs: In cancer immunotherapy, the therapy targets specific organs with cancer cells.

Who Needs Immunotherapy?

Immunotherapy may be suitable for people with:

• Certain types of cancer (e.g., melanoma, lung cancer, lymphoma)
• Allergies that are unresponsive to standard treatments
• Autoimmune diseases such as multiple sclerosis or rheumatoid arthritis
• Chronic viral infections such as hepatitis B or HIV

Costs & Coverage

In the UK, immunotherapy treatments are available on the NHS for certain conditions, particularly cancer. However, some newer immunotherapy options may only be accessible privately. Costs can range from £5,000 to £100,000+ depending on the type and duration of treatment. Private insurance may cover some immunotherapy treatments.

Health Symptoms & Illnesses

Immunotherapy is commonly associated with the treatment of:

• Cancer (melanoma, lung cancer, leukemia, etc.)
• Allergies (pollen, dust mites, venom, etc.)
• Autoimmune conditions (rheumatoid arthritis, lupus, multiple sclerosis)
• Chronic infections (HIV, hepatitis B)

Health Professionals

• Oncologist: Specializes in cancer treatment, including immunotherapy.
• Allergist/Immunologist: Focuses on allergies, immune disorders, and immunotherapy.
• Rheumatologist: Treats autoimmune diseases with immunotherapy options.
• Hematologist: Manages blood disorders, some of which involve immunotherapy.
• Nurse Practitioner: Provides patient education, assists in the administration of immunotherapy, and monitors side effects.

Questions to Ask

• Is immunotherapy the right treatment for my condition?
• What are the possible side effects?
• How long will I need to continue treatment?
• How will we monitor the effectiveness of the therapy?
• Are there any lifestyle changes I should make during treatment?

Immunotherapy Process

Before the Procedure

• Initial consultation and diagnosis.
• Assessment of the patient’s medical history and overall health.
• Blood tests and imaging studies to determine treatment suitability.

During the Procedure

• Administered through various methods (intravenous infusion, injections, pills, or topical application).
• Sessions can last 30 minutes to several hours, depending on the type of therapy.
• Monitored for adverse reactions during and after treatment.

After the Procedure

• Regular follow-ups to assess treatment response.
• Monitoring for delayed side effects.
• Blood tests and imaging to track progress.

Recovery Process

Recovery time varies depending on the type of immunotherapy and the patient’s condition. Some patients experience mild fatigue, while others may require more extended recovery periods.

Preparation

Nutrition Dos and Don’ts

Dos:

• Eat a balanced diet rich in fruits, vegetables, and lean protein.
• Stay hydrated.
• Consume foods high in antioxidants.

Don’ts:

• Avoid processed foods and excessive sugar.
• Limit alcohol consumption.
• Refrain from taking supplements without consulting your doctor.

Lifestyle Dos and Don’ts

• Stay physically active as recommended.
• Follow your doctor’s advice regarding work and daily activities.

Don’ts:

• Avoid exposure to infections and sick individuals.
• Refrain from smoking.
• Do not skip follow-up appointments.

Results

The time frame for seeing results varies. In cancer immunotherapy, some patients respond within weeks, while others may take months. Regular tests and imaging help monitor progress. Allergy immunotherapy may take several months to show full effectiveness.

Diagnosis

Immunotherapy is not primarily used for diagnosis but helps monitor and manage chronic diseases. For instance, response to cancer immunotherapy can indicate the progression of the disease.

Risks and Benefits

Risks

• Flu-like symptoms (fever, chills, fatigue)
• Allergic reactions
• Autoimmune responses

• Fewer long-term side effects compared to chemotherapy.
• Can provide long-lasting protection.

Alternatives

• Chemotherapy
• Radiation Therapy
• Targeted Therapy
• Surgery
• Traditional Allergy Treatments

Health Monitoring

Regular blood tests, imaging studies, and clinical assessments are essential to monitor the patient’s response. Health professionals watch for any adverse reactions and adjust treatment as necessary.
