what is the genetic marker that allows immunology as treatment for cancer

Full Answer

What are biomarkers in cancer immunotherapy?

In the context of cancer immunotherapy, biomarkers can provide insights into each patient’s individual cancer—its genetic makeup, its behavior, and its interactions with the immune system—which doctors can then use to determine the approach most likely to benefit a particular person. What types of biomarkers are there?

How is genetic testing used to diagnose cancer?

A different type of genetic testing, called tumor DNA sequencing, is sometimes done to determine if cancer cells of people who have already gotten a cancer diagnosis have genetic changes that can be used to guide treatment. Although some of these cancer cell changes may be inherited, most occur randomly during a person’s lifetime.

What is genomic biomarker testing for cancer?

Doctors usually suggest genomic biomarker testing (also called genomic profiling) for people with cancer that has spread or come back after treatment (what’s called advanced cancer ).

Biomarkers in the clinic

Already, several biomarkers have been incorporated (to varying degrees) into clinical practice, while others’ value has only recently been recognized and is still being explored. Some of the most promising biomarkers today in the context of immunotherapy include:

Biomarkers Moving Forward

Ultimately, there is unlikely to be a single, perfect biomarker that will apply in all cases because the importance of various biomarkers is likely to depend on what type of cancer a patient has as well as what type of immunotherapy he or she receives.
