Japanese, American scientists win Nobel Prize for breakthrough cancer treatment


Those discoveries sparked a revolution for specific cancer treatments.

"This important discovery has opened a whole new area of cancer treatment and we are proud of both Dr. Allison and Dr. Honjo's impactful research", said Janet Rossant, president and scientific director of the Toronto-based Gairdner Foundation.

One of Carter's treatments was a drug that blocked the immune-cell "brake" studied by Honjo.

The American and Japanese researchers discovered methods of removing the brakes on cells that fight invaders, paving the way for cancer immunotherapy, which has joined surgery, radiation and chemotherapy as a major weapon in the battle against cancer. "I didn't set out to study cancer, but to understand the biology of T cells, these incredible cells to travel our bodies and work to protect us".

"It's like your body uses your own army to fight cancer", she said. "A driving motivation for scientists is simply to push the frontiers of knowledge".

In 2012, a pivotal study demonstrated clear results for patients with different types of cancer.

"When I'm thanked by patients who recover, I truly feel the significance of our research", Honjo said during a news conference at the Japanese university, reports Grady for The New York Times. "I had lung cancer and I thought I was playing my last round of golf, but now I am able to play golf again".

The physics prize is to be announced Tuesday, followed by chemistry. In a key mouse experiment around Christmas 1994, Allison found that when mice with cancer were treated with CTLA-4-blocking antibodies, they were cured.

The discoveries led to the creation of a multibillion-dollar market for new cancer medicines.

The discovery led to effective treatments, specifically some called immune checkpoint blockade therapies.

Allison discovered the first of these built-in brakes, known as checkpoints, in the course of his immunology research in the early 1990s. This year, two leading immunologists with a formidable reputation in their respective fields, took home the title for their work in inhibiting negative immune regulations for the treatment of cancer.

"In some patients, this therapy is remarkably effective", Jeremy Berg, editor-in-chief of the Science family of journals, told the AP.

Allison said the biggest challenge with immunotherapy now is to learn why it helps some patients but not others - and how to combine it with traditional therapies to improve outcomes and reduce side effects. It was because of a sexual misconduct scandal that led to the decision was the Nobel assembly.

Other Nobel Prizes for 2018 will be announced from October 2 to October 8, 2018.

They winners will receive their prize from King Carl XVI Gustaf at a ceremony in Stockholm on December 10, the anniversary of the 1896 death of Alfred Nobel, who created the prizes in his last will and testament.
