Detection of high-risk #polyps at screening colonoscopy indicates risk for #liver and #biliary #cancer death

aledopress

Hepatobiliary cancers share risk factors with colorectal cancer (CRC), but there are no combined screening programs for these conditions.AimsThe aim of this study was to assess whether patients with high-risk colonic polyps are more likely to die from liver related tumors than patients with a negative colonoscopy.MethodsIn this retrospective analysis of mortality data, Austrian screening… Continue reading Detection of high-risk #polyps at screening colonoscopy indicates risk for #liver and #biliary #cancer death

Arid1a mutation suppresses TGF-β signaling and induces cholangiocarcinoma

aledopress

Activating KRAS mutations and functional loss of members of the SWI/SNF complex, including ARID1A, are found together in the primary liver tumor cholangiocarcinoma (CC). How these mutations cooperate to promote CC has not been established. Using murine models of hepatocyte and biliary-specific lineage tracing, we show that Kras and Arid1a mutations drive the formation of CC and tumor precursors from the biliary compartment,… Continue reading Arid1a mutation suppresses TGF-β signaling and induces cholangiocarcinoma
