Question: Are mutational status of KIT and PDGFRA and expression of PDGFRA associated with prognosis after curative resection of primary gastrointestinal stromal tumors ( GISTs )?

no

Question: Does presurgical transarterial chemoembolization increase biliary stricture incidence in orthotopic liver transplant patients?

These findings corroborate the safety of TACE in the treatment of hepatocellular carcinoma in potential OLT patients as a bridge to transplantation.
no
