Abstract

Aim: Essential thrombocythemia (ET) patients exhibit higher mean platelet volume (MPV) values compared to the healthy individuals. However, the association of degree of bone marrow fibrosis with either MPV or platecrit (PCT) has not been evaluated previously. The aim of this study was to investigate MPV and PCT values as predictive markers for evaluating bone marrow fibrosis (BMF) in ET patients. 

Methods: We conducted a retrospective cohort study to analyze the data of ET patients, who were followed in out-patient clinic of our hematology department, between January 2015 and December 2016. Patients older than 18 years, who had bone marrow biopsy, CBC, biochemistry tests and an abdominal sonography performed at the time of diagnosis, JAK2 test ordered and were BCR-ABL negative were included in the study. The patients were divided into two groups according to the presence of BMF as “the BMF group” and “the non-BMF group”. The cut-off value for MPV and PCT was determined according to the median value. Fisher’s exact test and χ2 were used for comparative statistical analysis.

Results: There were 22 males and 26 females with a median age of 56 years (range, 28–81). The BMF group included 35 (73%) patients while the non-BMF group included 13 (27%) patients. The median MPV was 8.8 fL (6.6-11.5) and median PCT was 0.69% (0.42-2.26), which was considered as the cut-off values for these parameters. There was no significant difference between the groups in patients with MPV ≤8.8 fL and MPV >8.8 fL (p=0.104) and also in patients with PCT ≤0.69% and PCT >0.69% (p=0.616).

Conclusion: There is no association between the BMF and MPV and PCT in ET patients. However this is the first study investigating the role of both MPV and PCT in BMF in ET patients.
