Today just over three per cent of pancreatic cancer patients survive for at least five years, only a fraction more than the two per cent who survived that long in the early 1970s. Across all cancers, half of patients now survive at least twice that long. But most cases of pancreatic cancer go undetected until it is too late for surgery. …
Every year 8,800 people are diagnosed with the disease in the UK but survival rates remain very low, with only three per cent of people diagnosed with pancreatic cancer surviving their disease for five years or more after their diagnosis. Cancer Research UK has made pancreatic cancer research a priority, and has the bold ambition to more than double its annual spend of £6million on research into the disease over the next five years. The charity is investing in fundamental biology investigating how the cancer spreads as well as trials looking at boosting the effectiveness of the standard chemotherapy treatments in pancreatic cancer patients. While more research is needed to find better ways of diagnosing and treating the disease, there is evidence to suggest that some pancreatic cancers are linked to being overweight and to smoking — and almost four in 10 could be prevented by lifestyle changes to address this…

Researchers from the Perelman School of Medicine at the University of Pennsylvania have found that epigenetic factors play a role in senescence. Epigenetic factors act on the structures in which genes reside, called chromatin. They found that senescent cells appear to undergo changes in their chromatin and find similar changes in cells that are prematurely aging. Their observations take place deep within cells — inside the chromatin of a cell’s nucleus. …
