Immunotherapy in Pancreatic Cancer- Harness your Immune System for Treatment

Immunotherapy in Pancreatic Cancer- Harness your Immune System for Treatment

Pancreatic cancer is one of the most challenging cancers to diagnose and treat. The reason being that the cancer is typically detected at an advanced stage, with a five-year survival rate of less than 10%. Traditional treatment methods like surgery, chemotherapy, radiation therapy, and immunotherapy in pancreatic cancer have limited effectiveness in this disease.

However, recent breakthroughs in cancer research have given rise to a promising development: immunotherapy. This innovative approach seeks to leverage the body’s immune system to combat cancer. In this blog, we will explore the role of immunotherapy in pancreatic cancer treatment, focusing on its application across different stages of the disease. We’ll also discuss the various immunotherapies available and the ongoing research and challenges in this field.

Understanding the Stages of Pancreatic Cancer

Pancreatic cancer typically progresses through several stages, which include:

Stages of pancreatic cancer

Stages of Pancreatic Cancer

Pancreatic Cancer – Stage 0

Also known as carcinoma in situ, cancer cells are confined to the top layers of the pancreatic duct lining and have not invaded nearby tissues or spread to other organs.

Pancreatic Cancer – Stage 1

At this stage, cancer is localised to the pancreas. It may involve either the head or body/tail of the pancreas.

Pancreatic Cancer – Stage 2

The cancer has typically spread to nearby lymph nodes but is still limited to the pancreas.

Pancreatic Cancer – Stage 3

Cancer has spread to major blood vessels near the pancreas and may also involve nearby lymph nodes.

Pancreatic Cancer – Stage 4

At this advanced stage, the cancer has metastasized to distant organs, such as the liver, lungs, or peritoneum.

Immunotherapy in Different Stages of Pancreatic Cancer

Immunotherapy offers a glimmer of hope at all stages of pancreatic cancer, but its effectiveness can vary depending on the disease’s progression.

Early-Stage Pancreatic Cancer (Stage 0 and 1)

In the early stages, surgery is the primary treatment option if the cancer is operable. However, immunotherapies can play a role in improving the outcomes of surgery by targeting any remaining cancer cells or reducing the risk of recurrence. Therapeutic vaccines and immune checkpoint inhibitors are being explored as potential adjuvant treatments in these cases.

Locally Advanced Pancreatic Cancer (Stage 2 and 3)

For locally advanced pancreatic cancer, where surgery may not be an option, immunotherapy can be used in combination with chemotherapy or radiation therapy to enhance the body’s immune response against the tumor. Clinical trials are underway to evaluate the efficacy of immune checkpoint inhibitors, such as pembrolizumab and nivolumab, in combination with standard treatments.

Advanced Pancreatic Cancer (Stage 4)

In cases of advanced pancreatic cancer, where the disease has metastasized, immunotherapy can help manage the cancer and improve the patient’s quality of life. Immune checkpoint inhibitors, targeted therapies, and CAR T-cell therapy are being explored as potential treatment options. These therapies aim to slow down the progression of the disease and alleviate symptoms.

Immunotherapy in Pancreatic Cancer – Challenges and Ongoing Research 

Immunotherapy, while promising, faces several challenges in the treatment of pancreatic cancer:

Immune Suppression

 Pancreatic cancer can create an immunosuppressive microenvironment that hinders the body’s natural immune response, making it difficult for immunotherapies to be effective.

Patient Selection

Identifying which patients most likely benefit from immunotherapies is a critical challenge. Personalised medicine approaches are being developed to tailor treatments to individual patients.

Combination Therapies

Researchers are actively investigating immunotherapy combinations with chemotherapy, radiation, or other targeted therapies to enhance the overall response rate.

Clinical Trials

Ongoing clinical trials are essential to gather data on the long-term benefits and potential side effects of immunotherapies in different stages of pancreatic cancer.

Take a look at “What You Need To Know About Immunotherapy


Immunotherapy has emerged as a beacon of hope in the treatment of pancreatic cancer, a disease known for its aggressiveness and limited treatment options. As our understanding of the immune system, cancer biology, and personalised medicine advances, immunotherapy is becoming an increasingly significant part of the treatment landscape for pancreatic cancer. While challenges persist, ongoing research and clinical trials offer optimism for the development of more effective and tailored treatments that harness the power of the immune system to combat pancreatic cancer at all stages of the disease.


1. What is immunotherapy, and how does it work in the context of pancreatic cancer?

Immunotherapy is a treatment approach that harnesses the body’s immune system to identify and destroy cancer cells. In pancreatic cancer, it aims to enhance the immune response against cancer cells, either by removing the “brakes” that inhibit immune activity or by training the immune system to target specific proteins on cancer cells.

2. Is immunotherapy a suitable treatment option for all stages of pancreatic cancer?

Yes, but its effectiveness varies. It may be used in combination with surgery, chemotherapy, or radiation therapy in the early stages. In contrast, in advanced stages, it can help manage the disease and improve a patient’s quality of life.

3. What are some common types of immunotherapy used in pancreatic cancer treatment?

Common types of immunotherapy for pancreatic cancer include immune checkpoint inhibitors (e.g., pembrolizumab and nivolumab), CAR T-cell therapy, and therapeutic vaccines.

4. Are there any specific immunotherapies that have shown promise in clinical trials for pancreatic cancer?

Immune checkpoint inhibitors, such as pembrolizumab and nivolumab, have shown potential in clinical trials for advanced pancreatic cancer. However, ongoing research is exploring other therapies and combinations.

5. What challenges does immunotherapy face in treating pancreatic cancer and are there any side effects?

Pancreatic cancer can create an immunosuppressive microenvironment, making it difficult for immunotherapies to be effective. Identifying which patients will benefit from these treatments and developing effective combination therapies are ongoing challenges.

Like any medical treatment, immunotherapy can have side effects. The nature and severity of these side effects may vary, but they are typically manageable and can include fatigue, skin rashes, and autoimmune reactions. Patients need to discuss potential side effects with their healthcare team.

6. How can I find out if immunotherapy is a suitable option for my pancreatic cancer treatment?

To determine whether immunotherapy is suitable for your specific case, consult with your oncologist or healthcare team. They will consider your cancer stage, overall health, and other factors before recommending treatment.

7. Are there ongoing clinical trials for immunotherapy in pancreatic cancer?

Yes, numerous clinical trials are exploring various immunotherapies and combinations for pancreatic cancer. If you’re interested in participating in a clinical trial, discuss this option with your healthcare provider.

8. What is the future outlook for immunotherapy in pancreatic cancer treatment?

As our understanding of the immune system and cancer biology advances, and with ongoing research and clinical trials, we can expect more effective and personalized treatments that leverage the immune system to combat pancreatic cancer.
