Trend of circulating CD34⁺ cells in patients with myelofibrosis: Association with spleen response during ruxolitinib treatment.

ABSTRACT: We evaluated CD34⁺ cells in a single-centre series of 49 consecutive patients with myelofibrosis (MF) at baseline and during ruxolitinib therapy and examined any association with spleen response. The median (range) absolute number of circulating CD34⁺ cells was 0.0835 (0.001-1.528) × 10⁹ /L at diagnosis, and 0.123 (0.002-1.528) × 10⁹ /L at ruxolitinib start. With the exception of a transient increase after 3 months of ruxolitinib therapy, a progressive reduction in CD34⁺ cells count was documented, down to a minimum of 0.063 × 10⁹ /L after 36 months. We then assessed the association between spleen diameter expressed as the distance from the left costal margin (outcome) and log(CD34⁺ ) cells count using random-inte
