10-40.0), only 2 as a result of non-liver-related death. The remaining 49 were alive after a median of 55 months (range, 0.7-69.0). Uni- and multivariable analysis for intervention-free
survival is detailed in Supporting Table 5. The Rotterdam score had an excellent prognostic value, and no further variable could significantly improve its prognostic ability. This validates the Rotterdam score as a useful prognostic tool in this post-therapeutic series of BCS. Supporting Fig. 2 shows survival curves for Rotterdam class I, II, and III. Because the Rotterdam score includes the INR, which could not be RG7204 order calculated in a substantial number of patients (already on oral anticoagulants), we performed a multivariable analysis without including scores or INR. Baseline ascites, bilirubin, and creatinine were independently associated with intervention or death (BCS-intervention-free survival prognostic score [BCIS score]: ascites
[yes = 1, no = 0]*1.675 + ln creatinine [umol/L]*0.613 + ln bilirubin [umol/L]*0.440). This data-driven new score showed an adequate discrimination BAY 80-6946 chemical structure (area under the curve [AUC] = 0.819), but it did not outperform the Rotterdam score (AUC, 0.821)9 (Supporting Fig. 3). The probability of intervention-free survival among different intervals of the BCIS score is shown in Supporting Table 7. Thirty-six patients (23%) died during the study. Median time to death was 10 months (range, 0.1-41.0). Main causes of death are reported in Table 2. Factors associated with mortality are shown in Supporting Table 6. The BCS-TIPS PI score was strongly associated with the risk of death, so that no other variable could improve its predictive capacity. Supporting
Table 8 shows survival among different ranges of BCS-TIPS PI scores. Because this score includes the INR, we performed a multivariable analysis excluding all scores and INR. Age, bilirubin, and creatinine were independently associated these with survival [BCSurvival score: age/10*0.370 + ln creatinine [umol/L]*0.809 + ln bilirubin [umol/L]*0.496). The discriminative capacity was comparable to that of the BCS-TIPS PI score and better than the Rotterdam score (Supporting Fig. 4). BCS is a rare, life-threatening disorder caused by obstruction of hepatic venous outflow. Until recently, most evidence regarding BCS was generated in small retrospective studies of patients diagnosed over long periods and managed using heterogeneous strategies.7, 9, 14 However, an international initiative, funded by the Fifth Framework Program of the European Commission, entitled the EN-Vie, was able to prospectively gather a large multicenter cohort of consecutive patients with BCS diagnosed and treated following homogeneous criteria.4 Previous retrospective studies evaluating prognosis in BCS showed that fatal events occur throughout the first 5 years after diagnosis.
