Comorbidities predict worse prognosis in patients with primary myelofibrosis

Comorbidities have been shown to play an important role in the prognostic assessment of several hematologic conditions; however, the role of comorbidities in primary myelofibrosis has not been studied. The objective of the current study was to evaluate the prevalence and impact of comorbidities in patients with primary myelofibrosis (PMF) using the Adult Comorbidity Evaluation‐27 (ACE‐27).
