Hyaluronan (HA) is a naturally occurring polysaccharide. “HA is secreted in excessive amounts in many pancreas cancers into the interstitium,” said Sunil R. Hingorani, MD, PhD, of the Fred Hutchinson Cancer Research Center in Seattle.

The subsequent decrease in fluid pressures can improve blood flow, allowing better drug delivery to the tumor bed. Read more . . .
