Topic: VA, Vets & CC Statistics
I recently came across an abstract from the 2008 Gastrointestinal Cancers Symposium. The abstract, "Intrahepatic versus extrahepatic cholangiocarcinoma: Is there a difference in survival?", speaks to survival stats of cc patients from Veterans Affairs (VA) Medical centers. The study queried the VACCR database for all diagnosed bile duct cancer cases between 1995 and 2005 & determined that a total of 825 cases of cholangiocarcinoma (including EHCC & IHCC) were identified. The analysis appears to speak to an exclusive VA patient base.
The same author was part of another presentation at the symposium which indicated that between 1973 and 2004 (~30 yrs) there were 13,676 cases of CC included in the NCI SEER database. Per the SEER population, there were 8,057 cases of cc diagnosed between 1995 & 2004. Moreover, an astounding ~40% of all diagnosed cases from 1973-2004 occured between 2000-2004... Suggesting that either the cancer or the diagnosis of it is on the rise perhaps.
It's not clear if the SEER stats are mutually exclusive of the VA stats.
