Cancer Immunotherapy Awareness Month

Empowering Immunity, Defeating Cancer

It is an impressive milestone to celebrate the 11th annual cancer immunotherapy awareness month in June 2023. The progress made in the field of cancer immunotherapy over the past decade has been remarkable and has transformed the landscape of cancer treatment. 

Cancer Immunotherapy Awareness Month 2023 Theme

Follow Effective Action With Quiet Reflection!

The theme for Cancer Immunotherapy Awareness Month 2023 underscores the call to action to raise awareness about cancer immunotherapy and its benefits, encouraging individuals to become informed, engaged and support this innovative technique for cancer treatment. It aims to increase public knowledge to drive further progress in improving cancer care outcomes through immunotherapeutic approaches.

Understanding Cancer Immunotherapy
 

Definition
 

Cancer immunotherapy is a type of treatment that controls the body's immune system to recognize and destroy cancer cells. It works by stimulating or enhancing the immune response to specifically target cancer cells while sparing healthy cells.
 

Principles
 

• Immune recognition: It identifies abnormal cancer cells as foreign or "non-self" due to the presence of specific molecules called antigens.
• Immune activation: Immune cells, such as T cells, are activated to recognize and attack cancer cells. This activation can be enhanced through various mechanisms.
• Immune memory: The immune system retains the memory of cancer cells it has encountered, allowing it to mount a more rapid and respond effectively upon re-exposure.
   

Different Types of Cancer Immunotherapy
 

There are several types of cancer immunotherapy, and each type strengthens the immune system's ability to combat cancer.
 

1. Monoclonal Antibodies: The antibodies are laboratory-produced molecules that recognize specific proteins in cancer cells. They can directly target cancer cells, trigger immune responses against them, or deliver toxins to cancer cells.
    
2. Checkpoint Inhibitors: The drugs that block the proteins known as immune checkpoints, such as PD-1 and CTLA-4, which regulate immune responses. By inhibiting these checkpoints, they help remove the blocks on the immune system, allowing it to attack cancer cells more effectively.
    
3. Adoptive Cell Transfer: It involves collecting a patient's immune cells, particularly T cells, and modifying or enhancing them in the laboratory to improve their cancer-fighting abilities. These modified cells are then reintroduced into the patient's body to target and eliminate cancer cells.
    
4. Cancer Vaccines: It stimulates the immune system to attack and recognize cancer cells. They can be composed of cancer-specific antigens, immune-stimulating substances, or genetically engineered viruses.
    
5. Cytokines: The proteins made naturally by the immune system. Immunotherapy can involve using cytokines, such as interleukins or interferons, to enhance immune cell activity and promote the destruction of cancer cells.
    

Strategies To Bring Out Awareness 
 

One of the key objectives of Cancer Immunotherapy Awareness Month is to increase public knowledge and understanding of cancer immunotherapy. Many people may not be aware of the existence or effectiveness of immunotherapy as a treatment option for cancer. By raising awareness, individuals can learn about immunotherapy's principles, benefits, and limitations, enabling them to make informed decisions about their healthcare or support loved ones who may be undergoing immunotherapy treatment.
 

Benefits And Limitations Of Cancer Immunotherapy
 

Cancer immunotherapy offers several benefits,
 

• Targeted Treatment: Immunotherapy specifically targets cancer cells while sparing healthy cells, thereby reducing side effects.
• Prolonged Responses: Some patients experience long-lasting responses and prolonged periods of remission.
• Improved Survival Rates: Immunotherapy has significantly improved survival rates for developing certain cancers.
   

There are also limitations to consider,
 

• Response Variability: Not all patients respond to immunotherapy, and response rates can vary depending on the type and stage of cancer.
• Side Effects: Immunotherapy can cause immune-related adverse events, such as inflammation of organs or autoimmune reactions.
• High Costs: Some immunotherapy treatments can be expensive and may not be accessible or affordable for all patients.
• Research and Development: Ongoing research is needed to optimize treatment strategies, identify predictive biomarkers, and overcome resistance mechanisms.
   

New Combination Regimen For Cancer Immunotherapy
 

Combination regimens in cancer immunotherapy involve combining different treatment modalities to enhance the effectiveness of immune system activation and improve patient outcomes. 
 

Here are some new and emerging combination approaches being explored:
 

• Immune Checkpoint Inhibitors (ICIs) with Targeted Therapies:

Combining ICIs with targeted therapies that specifically block certain molecular pathways implicated in cancer growth and survival. For example, combining ICIs with targeted drugs like BRAF inhibitors in melanoma or EGFR inhibitors in lung cancer has shown improved response rates and prolonged survival. 

• Dual Immune Checkpoint Blockade:

Simultaneously targeting multiple immune checkpoints to enhance immune activation. Combining antibodies against PD-L1 and CTLA-4, such as nivolumab and ipilimumab, can achieve synergistic effects and improved responses in melanoma and renal cell carcinoma.

• Immunotherapy with Chemotherapy:

Combining immunotherapy with traditional chemotherapy drugs. Chemotherapy can enhance immune responses by creating a more favourable tumor microenvironment for immunotherapy to work effectively. This combination has shown success in lung cancer, bladder cancer, and other malignancies.

• Immunotherapy with Radiation Therapy:

Combining immunotherapy with radiation therapy can enhance the immune response against tumors. Radiation can induce tumor cell death and release tumor antigens, which can prime the immune system for a more robust response when combined with immunotherapy.

• Novel Targeted Immunotherapies:

Developing new targeted immunotherapies that specifically address unique aspects of the tumor microenvironment or immune response pathways. Examples include bispecific antibodies, oncolytic viruses, and engineered immune cells with enhanced capabilities.
 

Advancements In Research And Development
 

The success and importance of cancer immunotherapy have driven increased research and development efforts in this field. Scientists and researchers continue to explore new immunotherapeutic strategies, develop novel drugs and delivery systems, and conduct clinical trials to expand the applications and effectiveness of immunotherapy.
 

It Only Takes One Person To Mobilize A Community Through Awareness
 

Cancer Immunotherapy Awareness Month 2023 focuses on an opportunity to recognize the advancements of immunotherapy in cancer patients. By increasing awareness, promoting research, and highlighting the importance of immunotherapy, this awareness month contributes to the continued progress and impact of cancer immunotherapy in improving patient outcomes and transforming cancer treatment.
