Various systems for predicting the prognosis of patients with myelodysplastic syndromes (MDS) have been developed. However, associations between performance status (PS) and prognosis of MDS require further investigation. To objectively assess the impact of PS on survival, we examined laboratory findings associated with PS, including serum levels of C-reactive protein (CRP), albumin (ALB), and total cholesterol (CHOL). Patients (n = 123; male 86, female 37; median age 74 yrs.) diagnosed with MDS or myelodysplastic/myeloproliferative neoplasms at Kanazawa Medical University Hospital between 2010 and 2020 were enrolled and grouped by cutoff values determined by receiver operating characteristic analysis: 0.44 mg/dL for CRP, 4.0 g/dL for ALB, and 120 mg/dL for CHOL. The median follow-up period was 17.6 months. Kaplan-Meier analysis revealed that overall survival (OS) in the high CRP, low ALB, and low CHOL groups was significantly shorter than in the low CRP, high ALB, and high CHOL groups, respectively. Multivariable analysis revealed that elevated serum CRP was an independent prognostic risk factor independent of gender, bone marrow blast percentage, and cytogenetics.
