Immunotherapy for Digestive Organ Cancer: A New Hope in Treatment


In the realm of cancer treatment, the breakthrough known as immunotherapy has garnered significant attention. It represents a powerful weapon in the fight against various cancers, including those affecting the digestive organs. In this article, we’ll explore what immunotherapy is, how it works, the types of immunotherapy drugs available, their specific side effects, and the response rates observed when treating digestive organ cancers.

What’s the Meaning of Immunotherapy?

Immunotherapy, in the context of cancer treatment, is a groundbreaking approach that harnesses the body’s own immune system to combat cancer cells.

Unlike traditional treatments such as chemotherapy and radiation, which directly target cancer cells, immunotherapy stimulates the immune system to identify and destroy cancerous cells more effectively.

How Does Immunotherapy Work?

Immunotherapy employs various strategies to enhance the body’s natural defenses against cancer:

  • Checkpoint Inhibitors: These drugs block proteins that prevent immune cells from attacking cancer cells. Common checkpoint inhibitors like Pembrolizumab and Nivolumab have shown remarkable results in digestive organ cancers.
  • CAR-T Cell Therapy: This approach involves genetically modifying a patient’s immune cells to target cancer. Although primarily used for blood cancers, it shows promise in solid tumors too.
  • Cytokines: Interleukins and interferons are types of cytokines used to boost the immune response against cancer cells.
  • Monoclonal Antibodies: These lab-engineered antibodies can identify and bind to specific proteins on cancer cells, flagging them for destruction by the immune system.

Types of Immunotherapy Drugs

Immunotherapy drugs can be classified into several categories:

  • Checkpoint Inhibitors: These include drugs like Pembrolizumab, Nivolumab, and Ipilimumab, which target immune checkpoint proteins.
  • Cytokines: Interferon-alpha and interleukin-2 are examples of cytokines used in cancer treatment.
  • Monoclonal Antibodies: Drugs like Rituximab and Trastuzumab are monoclonal antibodies tailored for specific cancer types.
  • Cancer Vaccines: These vaccines stimulate the immune system to recognize and attack cancer cells. Sipuleucel-T for prostate cancer is a notable example.

Drug-Specific Side Effects of Immunotherapy

While immunotherapy offers significant advantages, it’s essential to be aware of potential side effects, which can vary depending on the drug used.

Common side effects may include fatigue, skin rashes, diarrhea, and flu-like symptoms.

However, severe side effects are rare but can include lung inflammation, colitis, and hormonal imbalances.

Response Rates After Immunotherapy for Digestive Organs

Response rates to immunotherapy vary based on the type and stage of cancer, as well as individual patient factors.

In some cases, digestive organ cancers, such as certain types of liver or colon cancer, have responded exceptionally well to immunotherapy, leading to significant tumor shrinkage and prolonged survival.

However, not all patients experience the same response, making ongoing research and personalized treatment plans critical.



In conclusion, immunotherapy represents a promising frontier in the fight against digestive organ cancers.

It empowers the body’s immune system to recognize and attack cancer cells, offering new hope and improved outcomes for many patients.

As research continues and new immunotherapy drugs are developed, the future looks increasingly bright for those battling these challenging diseases.
