Cancer immunotherapy wins the 2018 medicine Nobel Prize
10/01/2018 - 06:42 Physiology, CancerJames P. Allison of MD Anderson Cancer Center in Houston and Tasuku Honjo of Kyoto University in Japan have won the Nobel Prize in physiology or medicine for advances in harnessing the immune system to fight cancer.
All previous types of cancer therapy were directed at the tumor cell, but Allison’s and Honjo’s approach was to remove brakes that keep the immune system in check, unleashing...

There’s a new cervical cancer screening option
08/21/2018 - 11:00 Health, CancerFor cervical cancer screening, there’s a new option in town.
Women ages 30 to 65 can opt to have human papillomavirus, or HPV, testing alone every five years, according to new recommendations from the U.S. Preventive Services Task Force.
HPV testing alone joins two other alternatives that are still endorsed: an HPV test plus a Pap test every five years, or a Pap test alone every...

Cancer cells engineered with CRISPR slay their own kin
07/11/2018 - 14:00 Cancer, Biomedicine, GeneticsUsing gene editing, scientists have hoodwinked tumor cells into turning against their own kind.
Cancer cells circulating in the bloodstream have something of a homing instinct, able to find and return to the tumor where they originated. To capitalize on that ability, researchers engineered these roving tumor cells to secrete a protein that triggers a death switch in resident tumor cells...

Evidence grows that an HPV screen beats a Pap test at preventing cancer
07/03/2018 - 11:58 Health, Clinical Trials, CancerEvidence continues to grow that screening for human papillomavirus infection bests a Pap test when it comes to catching early signs of cervical cancer.
In a large clinical trial of Canadian women, pap tests more often missed warning signs of abnormal cell growth in the cervix than did HPV tests, researchers report July 3 in JAMA. As a result, at the end of a four-year period,...

How to make CAR-T cell therapies for cancer safer and more effective
06/27/2018 - 09:00 Cancer, Health, Clinical TrialsThis wasn’t 15-year-old Connor McMahon’s first time in the hospital. But the 107° fever he’d been running for three days had his dad frightened. The teen was hallucinating, talking gibberish and spouting curses.
“I thought he was going to die,” says Connor’s father, Don McMahon, who stayed close as his son received and recovered from an experimental treatment for leukemia. “It was really...
