Mayo Clinic Cancer Center researchers report aggressive surgical removal of as much cancer as possible throughout the abdomen in ovarian cancer patients is the best option for most women. Results of the study are published in the January issue of Obstetrics & Gynecology.
"This study provides further evidence that surgery to remove as much tumor as possible at the initial operation is the best option for most patients," says William Cliby, M.D., Mayo Clinic gynecologic oncologist and lead investigator of the study. "It helps to define a topic that is often debated within our specialty -- the benefit of radical surgery for advanced ovarian cancer patients." Dr. Cliby says that data demonstrate many surgeons choose the more cautious route of less surgical intervention, and this results in shorter overall survival.
Dr. Cliby and his team of researchers found that aggressive surgery greatly improves survival rates for patients with the most severe disease spread. They also found similar five-year survival rates in most cases for patients undergoing radical and non-radical surgery, indicating to the researchers that aggressive surgery is not a significant risk factor, but instead aids in survival. In those patients with the highest volume of disease (carcinomatosis), the researchers found that radical surgery greatly improved the five-year survival rates (44 percent versus 17 percent).

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
