The SOFT-score, P-SOFT-score, SALT-score and labMELD-score have been applied for the prediction of survival of liver transplant recipients after transplantation. We analysed the value of these scores for the prediction of short-term survival in high-risk liver transplant recipients with a labMELD-score ≥30.
MATERIAL/METHODS: Retrospective single-centre analysis including 88 consecutive liver transplants in adults between 01.01.2007 and 31.12.2010 with a pretransplant labMELD-score ≥30 and follow-up until the 31.12.2011. Combined and living-related liver transplants were excluded. ROC-curve analysis was used to calculate sensitivity, specificity and overall model correctness of prognostic models.
The P-SOFT-score demonstrated a significant influence on 1-year patient survival (p=0.045, Mann-Whitney-U test). Multivariate Cox regression analysis showed a significant influence of the P-SOFT-score on patient (p=0.013; Exp(B)=1.050; 95%CI: 1.010-1.091) and on graft survival (p=0.023; Exp(B)=1.042; 95%CI: 1.006-1.080). ROC-curve analysis showed areas under the curve (AUROCs) <0.5 for the SOFT-score, P-SOFT-score, SALT-score and the labMELD-score ≥30 for the prediction of 3-month patient and graft survival as well as 1-year patient and graft survival.
Our results imply that the SOFT-score, P-SOFT-score, SALT-score and labMELD-score ≥30 all have a sensitivity, specificity and overall model correctness that is unable to discriminate short-term survivors from non-survivors in a collective of high-risk liver transplant recipients sufficiently in order to guide clinical decision making in the current German transplant situation with decreasing numbers of deceased liver donors, decreasing donor organ quality and increasingly sick transplant candidates.
SOFT评分、P-SOFT评分、SALT评分和实验室MELD评分已用于预测肝移植受者移植后的生存情况。我们分析了这些评分对实验室MELD评分≥30的高风险肝移植受者短期生存预测的价值。
材料/方法:回顾性单中心分析,纳入2007年1月1日至2010年12月31日期间连续88例成年肝移植患者,移植前实验室MELD评分≥30,并随访至2011年12月31日。排除联合肝移植和活体亲属肝移植。采用ROC曲线分析计算预后模型的敏感性、特异性和整体模型正确性。
P-SOFT评分对患者1年生存率有显著影响(p=0.045,Mann-Whitney-U检验)。多因素Cox回归分析显示,P-SOFT评分对患者生存率(p=0.013;Exp(B)=1.050;95%CI:1.010-1.091)和移植物生存率(p=0.023;Exp(B)=1.042;95%CI:1.006-1.080)有显著影响。ROC曲线分析显示,SOFT评分、P-SOFT评分、SALT评分以及实验室MELD评分≥30用于预测3个月患者和移植物生存率以及1年患者和移植物生存率时,曲线下面积(AUROCs)<0.5。
我们的结果表明,在德国目前肝移植供体数量减少、供体器官质量下降以及移植候选者病情日益严重的移植情况下,SOFT评分、P-SOFT评分、SALT评分和实验室MELD评分≥30的敏感性、特异性和整体模型正确性均不足以充分区分高风险肝移植受者群体中的短期生存者和非生存者,从而指导临床决策。
