This after scientists from the Department of Biology at University of Texas in San Antonio claims they have developed a method that could wipe out cancerous tumours by killing the cancers cells.
A new method that wipe out cancerous tumours by killing it through suicide
In their study through The Journal of Clinical Oncology, lead researcher and associate professor Matthew Gdovin said that they patented the method that can tremendously help people with hard-to-reach or inoperable tumours , including young children with cancer.
Gdovin claims that their method involves a chemical compound called nitobenzaldehyde by injecting it in the tumour and allowing it to diffuse into the tissue. Once the chemical is in, they then aim a beam of light at the tissue that causes the cells to become acidic to the point that the cancer cell ‘commits suicide’ and dies.
In a matter of two hours, Gdovin said that up to 95% of the cancer cells die.
“Even though there are many different types of cancers, the one thing they have in common is their susceptibility to this induced cell suicide,” says Gdovin.
Successful animal testing
According to Gdovin, they initially tested the method against mice against triple negative breast cancer cells, which is one of the most aggressive of all cancer types and one of the most difficult to treat – often met with a poor prognosis for survival.
After only one round of treatment using the method, Gdovin said that they were able to stop the tumour dead in its tracks and doubles the test mice’s chances of survival.
“All forms of cancer attempt to make cells acidic on the outside as a way to attract the attention of a blood vessel, which attempts to get rid of the acid,” says Gdovin. “Instead, the cancer latches onto the blood vessel and uses it to make the tumour larger and larger.”
More precise than chemotherapy
While chemotherapy target all cells in the body and some therapies also involves keeping cancer cells acidic until they die re two of the main reasons why cancer patients start to lose hair and get sick.
This new method, however, aims to become a better alternative as it only targets the cancerous tumour without affecting other healthy cells in the body. It is also non invasive as the light wavelength that is used to activate the chemicals that are made up of nanoparticles that can pass through skin, flesh and bone until it reaches the targeted tumour cells.
Gdovin hopes that this non-invasive technique treat patients with tumours along problematic areas like the aorta, brain stem or spine and wipe out cancerous tumours without the need for surgery.
