| Outline of Final Research Achievements |
The purpose of was to determine the independent factors predicting the prognoses of biliary cancer. We conducted a retrospective study of 56 patients of biliary cancer. As FDG uptake parameters, SUVmax, SUVpeak, MTV, and TLG were calculated.The expression of KRAS, BRAF, EGFR, Ki-67, VEGFA and HIF-1 were measured by RT-PCR methods. Statistically significant shorter OS were noted in patients with FDG parameters higher than cut-off value, SUVmax (≧5),SUVpeak (≧4), and TLG (≧30) by univariate analysis, In addition, the poorly differentiated adenocarcinoma group had a significant shorter OS. However, oncogene expression were not significant independent factors. Regarding as the expression of oncogenes, it was not statistically significant.The multivariate analysis showed that the value of SUVmax, SUVpeak and the histopathological differentiation were independent prognostic factors. In the prediction of long-term prognosis, both SUVmax and SUVpeak are reliable prognostic factors.
