The Role of Genomics in Personalized Cancer Therapy

Chemotherapy is the most conventional and widely used approach to fighting cancer. But what if there is a personalized cancer treatment that suits you down to your every gene? Doctors use treatments that empower your genes to fight and defeat cancerous cells. Here’s where genomic cancer therapy transforms the possibility into precision care. It is designed to study the complete architecture of a cancer tumor for personalized treatment, evaluate drug response, and design new treatments. Understanding a tumor’s genetic changes allows oncologists to tailor treatments that hit cancer at its core, helping patients recover more effectively.

Where do Genomics come in?

Genomic profiling plays a pivotal role in targeted cancer therapy by identifying genetic mutations that fuel the tumor’s growth. It tailors drugs and doses for the destruction of the cancerous cells in the tumor. Genomic markers can predict the drug response of patients to a particular targeted drug. It categorizes cancerous tumors into different molecular subtypes, which leads to selecting specific treatment types. Genomic analysis helps analyze the resistance caused by certain targeted therapies, which can then be used to adjust the treatments. In simple terms, genomics ensures that every step of the treatment, from drugs to dosages, follows a unique genetic blueprint of the cancer tumor to make therapy more precise and effective.

Genomics and Cancer Treatment

Genomics provides targeted therapy, as it studies the mutation of cancer cells that results in the growth of the tumor. It provides treatment that has fewer side effects and improves the overall recovery rate. The following are a few benefits of why genomics is revolutionizing cancer treatment:

More Effective Treatments: Targeting the specific genetic drivers causing tumor growth, targeted therapies result in being more effective than conventional chemotherapy methods.

Fewer Side Effects: Because targeted therapy specifically attacks the cancerous cells, it is less likely to harm the healthy cells of the body. This results in fewer side effects and a balanced immune system for the patient.

Tailored Patient Care: Precision medicine enables the identification of genetic alterations in cancer cells, leading to the development of tailored treatments that suit an individual’s genetic profile for more precise care.

Barriers to Genomics in Cancer Treatment

Despite the performance and effectiveness of genomics in cancer care, it still faces hurdles in its total expansion. Genomics requires genome sequencing for creating the right and effective cancer treatment. While genome sequencing is gradually becoming less expensive, it can still be costly. This limits the access for some patients and leads to potential hindrance in cancer care. As genome sequencing requires specialized tools and generates tons of genetic data, there is still a lack of space for specialized labs and genetic test centers, which is a primary requirement for genomics. These challenges highlight that while genomics holds great potential, it can only be unlocked when affordability and infrastructure catch up with its progress.

How Genomics is Shaping Cancer Care

Technology is evolving with the times, and so is our cancer care, too. With genomics coming into the big picture, it has become more than just a science. By tailoring to the patient’s genetic profile, it not only improves the recovery rate but also shapes the future for a more patient-specific treatment.
