Success Rate of Immunotherapy: Here’s all you need to know

Immunotherapy has emerged as a groundbreaking approach in the field of cancer treatment.

But what is the success rate of immunotherapy? What does it depend on? And what is the future of this promising treatment?

By using the power of the immune system, immunotherapy aims to boost the body’s natural defenses against cancer cells.

The effectiveness of this innovation varies across different types of cancer and individual patients. But it has shown remarkable success rates in certain cases.

In this article, we will explore the success rate of immunotherapy and the factors influencing it. We will learn about its potential side effects of immunotherapy and its future advancements.

What is immunotherapy?

Simply put, immunotherapy is a treatment that boosts the power of the immune system to target and destroy cancer cells. It increases the body’s natural defense mechanisms to fight against cancer.

In recent years, the field of cancer treatment has witnessed significant advancements. Traditional treatments like chemotherapy or radiation therapy directly target cancer cells. But immunotherapy focuses on empowering the immune system to recognize and end cancer cells. This revolutionary approach has demonstrated promising results. It has improved outcomes for many cancer patients.

Understanding Immunotherapy

Before delving into the success rate of immunotherapy, it’s important to understand the basics of it. This form of treatment works by leveraging the body’s immune system to fight cancer. It uses different strategies to either stimulate the immune response or remove barriers that prevent the immune system from recognizing cancer cells.

Types of Immunotherapy

Immunotherapy involves many kinds of treatment approaches. Each of them have their own unique mechanisms. Different types of immunotherapy includes Monoclonal Antibodies, Immune Checkpoint Inhibitors, Adoptive Cell Transfer, Therapeutic Vaccines and CAR-T Cell therapy and more. It’s important to understand these types because the success of immunotherapy depends highly on this.

1. Monoclonal Antibodies: These laboratory-produced antibodies target specific proteins on cancer cells. Then they flag them for destruction by the immune system.
2. Immune Checkpoint Inhibitors: By blocking specific proteins called checkpoints, these inhibitors let the immune system recognize and attack cancer cells more effectively.
3. Adoptive Cell Transfer: This therapy involves extracting immune cells and modifying and multiplying them in a laboratory. Then they are reinfused into the patient’s body to increase the immune response.
4. Therapeutic Vaccines: These vaccines are designed to stimulate the immune system’s response against cancer cells. They are trained to recognize and destroy them.
5. CAR-T cell therapy: This approach involves modifying a patient’s T cells in a laboratory to express chimeric antigen receptors (CARs) that recognize and destroy cancer cells when infused back into the patient.

Mechanism of Action

The success of this treatment lies in its ability to activate the immune system’s response against cancer cells. It works by either boosting the immune system’s ability to target cancer cells directly or by enhancing the recognition and elimination of cancer cells.

Does Immunotherapy work on all types of cancers?

Immunotherapies have shown promising results in various types of cancer, including but not limited to:

• Melanoma
• Lung cancer
• Bladder cancer
• Kidney cancer
• Lymphoma
• Leukemia

The success rate can also vary depending on the specific cancer type and individual patient factors.

Immunotherapy Success Rate

To talk numbers, the overall success rate of immunotherapy is recorded to be between 20-50%. But, immunotherapy success rate is influenced by several factors. This includes: cancer type, Tumor characteristics, Patient’s Immune System and Combination Therapies.

• Cancer Type: Some types of cancer are more responsive to this treatment than others. For example, this therapy has shown exceptional results in metastatic melanoma and certain forms of lung cancer.
• Tumor Characteristics: The presence of specific molecular markers on cancer cells can indicate whether this therapy will be effective. Tumors expressing these markers are often more susceptible to these treatments.
• Patient’s Immune System: The patient’s overall health, immune function, and genetic makeup can impact the effectiveness of this therapy.
• Combination Therapies: Immunotherapy can be combined with other treatments like chemotherapy or radiation therapy to enhance its effectiveness. The success rate may vary depending on the chosen combination approach.

Clinical Trials

Clinical trials play a crucial role in determining the success rate of immunotherapies. These trials assess the effectiveness and safety of new treatments, helping researchers gather data and refine therapeutic approaches. The insights gained from clinical trials contribute to improving the success rate of this hopeful innovation and expanding its applications.

Real-Life Success Stories

Immunotherapy has transformed the lives of numerous patients, providing them with new hope and extended survival rates. Real-life success stories of individuals who have experienced significant benefits from this therapy highlight its potential and the impact it can have on cancer treatment outcomes.

One such inspiring story is that of Bob Carlson, 71, a stage 4 lung cancer patient. He endured the debilitating effects of chemotherapy until he discovered a clinical trial for a promising therapy drug called MPDL3280A. This drug, belonging to a class of checkpoint inhibitors, unleashed his immune system’s power to combat cancer.

After 16 months of starting this therapy, Bob’s tumors had shrunk, and he started responding well to the treatments. He now advocates for continued research funding and faster dissemination of research breakthroughs, hoping that more patients can access these life-saving treatments. Bob’s success story showcases the transformative potential of this approach in fighting cancer.

Immunotherapy Side Effects

While immunotherapy has shown tremendous promise, it is not without limitations and potential side effects.
This form of therapy can lead to side effects as it activates the immune system to target cancer cells. The specific side effects vary depending on the type of therapy, dosage, and individual factors.

Common side effects include fatigue, skin reactions at the injection site, flu-like symptoms, diarrhea, and nausea. Some people may experience more severe side effects. This could include organ inflammation, heart palpitations, fluid retention, sinus congestion, or infections. Severe reactions are rare. But it’s important to communicate any signs of side effects to healthcare professionals for appropriate management.

Future of Immunotherapy

The future of immunotherapy is incredibly promising. Researchers are continuously exploring novel approaches and combinations to improve its success rate further. Advancements in precision medicine and the development of personalized treatments hold immense potential for enhancing outcomes and expanding the application of this revolutionary treatment.
