Pancreas Cancer

Hi Cirel, I think CA19-9 is not elevated in all pancreatic cancer patients. If you go to the FAQ above, then go to 'how is pancreatic cancer diagnosed' then the link to CA19-9, under accuracy it states 'CA19-9 is elevated in the blood of 50-75% of individuals with CA19-9 is elevated in the blood of 50-75% of individuals with PC. Other blood tests such as CEA are not as accurate. Supplemental imaging studies and tissue samples are required with CA19-9 levels for a definitive diagnosis.'

From the number of people here on this board for whom CA19-9 is an indicator, I would have guessed the percentage of people with pancreatic cancer for whom the CA19-9 is elevated would have been higher. I guess this is another reason that pancreatic cancer is so hard to diagnose.

Take care, Diane
