The aim of this study was to evaluate the role of ANAs as a prognostic factor in CLL. Methods: This study retrospectively analyzed clinical data from 216 newly diagnosed CLL subjects with ANAs test from 2007 to 2017. Multivariate Cox regression analyses were used to screen the independent prognostic factors related to time to first treatment (TTFT), progression free survival (PFS) and overall survival (OS). Receiver operator characteristic curves and area under the curve (AUC) were utilized to assess the predictive accuracy of ANAs together with other independent factors for OS. Results: The incidence of ANAs abnormality at diagnosis was 13.9%. ANAs positivity and TP53 disruption were independent prognostic indicators for OS. The AUC of positive ANAs together with TP53 disruption was 0.766 (95% confidence interval [CI]: 0.697-0.826), which was significantly larger than that of either TP53 disruption (AUC:0.706, 95% CI:0.634-0.772, P=0.034) or positive ANAs (AUC:0.595, 95% CI:0.520-0.668,P<0.001) in OS prediction. Besides, serum positive ANAs as one additional parameter to CLL-international prognostic index (IPI) obtained superior AUCs in predicting CLL OS than CLL-IPI alone. Conclusion: This study identified ANAs as an independent prognostic factor for CLL, and further investigations are needed to validate this finding.展开更多
