We evaluated various prognostic factors and non\u2010curative surgical factors using multidetector computed tomography (MDCT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively analyzed 71 patients who underwent MDCT preoperatively and were scheduled for surgical resection of biliary cancer. For MDCT diagnosis, we used MDCT\u2010based classification equivalent to the surgical and pathological classification of the Japanese Society of Biliary Surgery. We evaluated MDCT\u2010related prognostic factors and non\u2010curative surgical factors and compared these factors with pathological results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>MDCT\u2010diagnosed category T (primary tumor invasion) included both prognostic factors and non\u2010curative surgical factors but not category N (lymph node metastasis). Multivariate analysis identified MDCT\u2010based suspected arterial invasion as an independent prognostic factor. In patients suspected of arterial invasion by MDCT, the 3\u2010year overall survival rate was only 39% and the curative resection ratio was only 33%, because of the high positive surgical dissected margin.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>MDCT\u2010based suspected arterial invasion is a predictor of poor prognosis after surgery for biliary cancer and represents a non\u2010curative surgical factor associated with positive dissected margin.
