Blood Counts May Remain Elevated in Polycythemia Vera Despite Treatment With Hydroxyurea
Real-world evidence—retrospective chart review
Treatment patterns among patients with PV in the United States were investigated in a retrospective chart review of 1309 patients.1
Elevated laboratory values for Hct, PLT count, and WBC count were assessed.1
More than 1/3 (40.3%) of patients with PV who were receiving HU had at least 2 elevated lab values.1

Hct, hematocrit; PLT, platelet; WBC, white blood cell.
aA retrospective chart review of 1309 patients with PV was conducted in the US between April 2014 and July 2014 by Incyte Corporation. The purpose was to investigate the treatment patterns among US patients with PV in a real-world setting. Hct ≥45%, WBC counts >10 × 109/L, and PLT counts >400 x 109/L were considered elevated values.
