The World On arirang

In 2015, former U.S. President Jimmy Carter was in critical condition after a tumor developed in his brain from skin cancer.
But thanks to immunotherapy, which utilizes our immune cells to battle cancer, he was cured.

"Immune cells treat cancer by attacking cancer cells. Cancer cells send signals to prevent immune cells from fighting back. That's called "PD-L1." The treatment serves as a counter to the signals, enabling immune cells to attack cancer cells."

Currently used to treat multiple cancers of the head, nose, liver, lungs, skin, and kidney,immunotherapy is considered a method that can unlock effective ways to treat more severe cancer patients.

A bio company in South Korea has developed a type of artificial intelligence technology that has deep-learned over one million cancer cell images.
It runs thorough analyses based on various criteria from immunostimulatory to immunodeficiency levels which allows it to drastically increase the odds of finding more patients eligible for immunotherapy.

"As for lung cancer, roughly forty percent of the patients are known to be treatable with immunotherapy while it doesn't work on the other sixty. But more among that sixty percent are reactive to the treatment. We found twenty more eligible patients out of sixty subjects by increasing the AI's precision."

Published in "Journal of Clinical Oncology" in March this year, the technology was recently certified as a medical device in Europe.
Developers also plan to earn FDA approval for use in U.S. within the next three years.
