Positive treatment results when using the immunotherapy drug Pembrolizumab (Keytruda) is a good sign for cancer patients, especially those with advanced, metastatic cancer. As one of the first hospitals in Vietnam to use Keytruda immunotherapy for cancer treatment, Vinmec is perfecting a multimodal cancer treatment model, opening up a lot of hope in the fight against cancer.
Immunotherapy: A new direction in the fight against cancer
The main cancer treatment methods include surgery, chemotherapy, radiation therapy.. In which, surgery and radiation therapy play an important role in the treatment of some cancers at an early stage, when the tumor is still localized (in situ, in the region).
Unfortunately, there is still a large percentage of patients who are found to have cancer at a late stage, or the disease has recurred and metastasized and is no longer able to undergo surgery or radiation therapy. At this time, chemotherapy is the main treatment. However, the results of chemotherapy are still limited and the side effects of chemotherapy often make it difficult for patients to continue long-term treatment. The birth of Keytruda immunotherapy has solved the above disadvantages, helping to increase the effectiveness of other therapies when combining treatment while minimizing unwanted side effects. This is the "revolutionary" discovery that brought the 2018 Nobel Prize in medicine to two scientists, Tasuku Honjo, 76 years old, from Japan, and James P. Allison, from the US.
How does the immune drug Keytruda affect cancer cells?
The body's immune system has the function of recognizing and destroying foreign cells. However, some cancer cells have the ability to make the immune system unable to recognize and destroy. Keytruda immunotherapy has been shown to be able to "neutralize" this ability of cancer cells, thereby helping immune cells recognize attacking cancer cells and destroy them.
According to Assoc. Prof. Dr. Nguyen Tuyet Mai - Head of Internal Oncology Department, Vinmec Times City International Hospital: “Keytruda immunotherapy only kills malignant cells without affecting normal cells. As a result, this therapy helps to minimize unwanted side effects and improve treatment results. On the other hand, treatment with Keytruda has a much higher response rate than conventional cancer chemotherapy. Elderly patients or patients with advanced disease such as metastatic cancer, .. can still hope in Keytruda”.
Indications for the use of immunosuppressant Keytruda
Since June 2019, the US Food and Drug Administration (FDA) has approved Keytruda for the following indications:
*TPS (total positive score): percentage of tumor cells (alive) positive for PD-L1; CPS (combined positive score): percentage of cells (including: tumor cells, lymphocytes, macrophages,... infiltrating the tumor) positive for PD-L1.

The whole country responded completely to treatment.
From those initial successes, Vinmec Hospital plans to expand the use of immunotherapy drugs to treat many other malignancies. Along with using Keytruda, patients will be combined with other therapies depending on the location of the lesion, such as combining autologous immune-boosting therapy, thermogenic therapy... to improve results. treatment.
