    Purpose: Early comorbidity detection has been reported to be associated with treatment-related outcomes in several diseases. Two main goals of the present study were to investigate both the impact of comorbidities and transfusion frequencies on the survival and quality of life of patients with myelodysplastic syndromes (MDS). Methods: One hundred and four MDS patients with a median International Prognostic Scoring System (IPSS) score of 0.5 (range: 0-3) were included in the study. Almost half of the patients had more than one comorbidity. Results: Median short form health surveys (SF)-36 mental and physical scores were 42.1 (range: 20.6-66.1) and 38.7 (range: 18-59.7), respectively. Mean scores of the Eastern Cooperative Oncology Group (ECOG) performance scales at diagnosis and during recruitment were 1.0 (1.4 +/- 1.0) and 2.0 (1.8 +/- 1.1), respectively. The mean Charlson Comorbidity Index (CCI) score was 1.0 (1.4 +/- 1.5). In the model that was constructed using variables with a p value < 0.100 in the univariate analysis, factors that predicted death were refractory anemia with excess blasts (RAEB) and ECOG scores at recruitment. When ECOG was removed from the model, RAEB and CCI at diagnosis moved to the forefront as mortality predictors. Conclusion: This study demonstrated that both CCI and ECOG performance status had an impact on survival in MDS patients who had low IPSS scores. ECOG stood out as a better and more practical predictor of survival than CCI, especially after considering its (ECOG) ease of use.
