06). At 5 years, the recurrence rate in both groups was similar (12% versus 14%; P = 0.94). Table 2 shows the results of univariate analysis for prognostic factors of recurrence in each group separately (LDLT and DDLT). The predictive factors of recurrence were similar in both groups, and were related to a more aggressive tumor (i.e., number of nodules, diameter of largest nodule, preoperative AFP levels, presence of satellite nodules and vascular invasion by the tumor) and to selecting patients beyond established and validated selection criteria (Milan and UCSF). The numbers of recurrences were small in both groups (LDLT, n = 4; DDLT, n = 27), hence a separate multivariate

analysis could not be performed. However, because the pattern of recurrence http://www.selleckchem.com/products/nu7441.html in both groups was similar, multivariate analysis was performed combining the 2 groups (all 31 patients who had recurrence after LT). On multivariate analysis, among the preoperative variables, transplantation patients with tumors beyond UCSF criteria (P = 0.007) emerged as an independent predictive factor for recurrence (Table 3). Edmonson grade III-IV (P = 0.04) and presence of microscopic vascular invasion (P = 0.009) on the specimen were the other independent poor predictive factors for recurrence. We tested only UCSF criteria in multivariate analysis and not Milan criteria, number, or diameter of nodules

(all of which were significant on univariate analysis) to obviate colinearity. UCSF criteria essentially include the Milan criteria. Similarly, patients with macroscopic vascular JNK inhibitor datasheet invasion are already included in the larger group of patients with microscopic vascular invasion. The OS in the two groups (LDLT versus DDLT) after listing (intention-to-treat) and after transplantation (only for those patients with HCC confirmed on the explanted liver) were similar (P = 0.68 and P = 0.36, respectively) (Figs. 2A,B). On multivariate analysis, blood transfusion and microscopic vascular invasion emerged as independent poor prognostic factors for OS

on an intention-to-treat basis (data not shown). There was a trend toward 上海皓元 worse survival outcomes in those patients beyond Milan or UCSF criteria who underwent LDLT compared with those who underwent DDLT (P = 0.06 in both cases) (Figs. 3 and 4). There was no difference in the site of recurrence between the two groups (P = 0.77). In the LDLT group, of the four recurrences, two patients had extrahepatic recurrences (one in the lungs and one in the bony skeleton), one patient had an intrahepatic recurrence, and one patient had a recurrence in the liver, lungs, and suprarenal glands. In the DDLT group, of the 14 recurrences, six patients had an extrahepatic recurrence (four pulmonary, one in the bony skeleton, and one in the adrenal glands), six patients had intrahepatic recurrence, and two patients had both intrahepatic and extrahepatic recurrence.
