Important advance made with new approach to 'control' cancer, not eliminate it (eg. ovarian cancer)

Researchers have created a new drug delivery system that could improve the effectiveness of an emerging concept in cancer treatment - to dramatically slow and control tumors on a long-term, sustained basis, not necessarily aiming for their complete elimination.
The approach, called a "metronomic dosage regimen," uses significantly lower doses of but at more frequent time intervals. This would have multiple goals of killing , creating a hostile biological environment for their growth, reducing toxicity from the and avoiding the development of resistance to the being used.
A system just published in Chemistry of Materials by a group of researchers from Oregon and the United Kingdom offers an even more effective way to deliver such drugs and may be able to greatly improve this approach, scientists say. Further testing is needed in both animals and humans for safety and efficacy.
"This new system takes some existing therapy drugs for , delivers both of them at the same time and allows them to work synergistically," said Adam Alani, an associate professor in the Oregon State University/Oregon Health & Science University College of Pharmacy, and lead author on the new study.
"Imagine if we could manage cancer on a long-term basis as a chronic condition, like we now do high blood pressure or diabetes. This could be a huge leap forward."
This approach is still in trial stages, Alani said, but shows promise. In some prior work with related systems in animal tests, OSU and collaborating researchers have been able to completely eradicate tumors.....
