Abstract
The prognosis of pT2 gallbladder cancer correlates with whether appropriate surgery for the spread of cancer has been performed Therefore accurate preoperative T staging is especially important We carried out this study to evaluate the usefulness of serial examinations by endoscopic ultrasound EUS and angiography for the T staging of pT2 gallbladder cancerMethods Fortyeight patients with gallbladder cancer who underwent both EUS and surgery between 1983 and 1998 were included in this study The accuracy of serial examination by both EUS and angiography in T staging based on previously established diagnostic criteria was retrospectively evaluated First the presence or absence of subserosal tumor invasion was assessed by EUS alone Second in equivocal cases the depth of tumor invasion was further evaluated by angiographic findingsResults Twentyfour patients were correctly diagnosed as having other than pT2 cancer by EUS alone Angiographic findings were reviewed in 19 of the remaining patients who had pT1 pT2 or a small number of pT3 lesions The sensitivity specificity and overall accuracy in the T staging of pT2 gallbladder cancer was 818 906 and 884 respectively
