Researcher develops non-invasive method to kill cancer cells in two hours
30 June 2016 Current Affairs GK: Matthew Gdovin, an associate professor in the University of Texas at San Antonio (UTSA) Department of Biology, developed a newly patented method to kill cancer cells.

Gdovin’s research was published on 27 June 2016 in The Journal of Clinical Oncology.

The discovery may help people with inoperable or hard-to-reach tumours.

Discovered the  method :  The research involved injecting a chemical compound, nitrobenzaldehyde, into the tumour and allowing it to diffuse into the tissue.

A beam of light was aimed at the tissue, which caused the cells to become very acidic inside. It forced the cells to commit suicide.

Thereafter, it was estimated that up to 95 percent of the targeted cancer cells were dead within two hours.

Effectiveness of the method : Gdovin tested the method against triple negative breast cancer, which is one of the most aggressive types of cancer and one of the hardest to treat.

The prognosis for triple negative breast cancer is usually very poor.After one treatment in the laboratory, he was able to stop the tumour from growing and double chances of survival in mice.
