The revised International Prognostic Scoring System (IPSS-R) was developed in a cohort of untreated myelodysplastic syndromes (MDS) patients. A French Prognostic Scoring System (FPSS) was recently reported to identify differential survival among azacitidine-treated patients with high-risk MDS. We applied the FPSS and IPSS-R to 150 patients previously randomized to azacitidine monotherapy or a combination of azacitidine with entinostat (a histone deacetylase inhibitor). Neither score predicted response but both discriminated patients with different overall survival (OS; median OS, FPSS: 9·7, 14·7, and 25·3 months, P = 0·018; IPSS-R: 12·5, 11·3, 20·8, and 36 months, P = 0·005). Statistical analysis suggested no improvement in OS prediction for the FPSS over the IPSS-R in azacitidine-treated patients.
修订后的国际预后评分系统(IPSS-R)是在一组未经治疗的骨髓增生异常综合征(MDS)患者中开发的。最近有一项法国预后评分系统(FPSS)报告称,它可以识别接受阿扎胞苷治疗的高危 MDS 患者的生存差异。我们将 FPSS 和 IPSS-R 应用于 150 名先前随机分配至阿扎胞苷单药或阿扎胞苷联合恩替诺特(一种组蛋白去乙酰化酶抑制剂)治疗的患者。这两个评分都不能预测反应,但都能区分总生存期(OS)不同的患者(中位 OS,FPSS:9.7、14.7 和 25.3 个月,P = 0.018;IPSS-R:12.5、11.3、20.8 和 36 个月,P = 0.005)。统计分析表明,FPSS 不能改善阿扎胞苷治疗患者的 OS 预测。
