Popis: | Background. Wt1 expression is thoroughly studied in acute myeloblastic leukemia and widely used for disease response monitoring.Its role in MPN is less known. Aim. The aim of the study was to reveal the incidence of elevated Wt1 expression in PMF and secondary MF, as well as to find out clinical significance during ruxolitinib therapy. Patients and methods. 38 pts were included ( Primary Mf-31, post PV- and post ET Mf- 8, males - 12, females- 26). Wt1 expression in peripheral blood was studied by qPCR at diagnosis and during ruxolitinib treatment using Quiagen kit. Dynamics of Wt1 expression was studied in 20 pts treated by ruxolininib. Spleen size was measured in cm below costal margin. Results. Wt1 increased expression was found in 35/38 pts. Correlation of Wt1 expression and DIPSS was not found. The relation between blast cell and Wt1 expression was studied by dividing pts in 3 subgroups according to the number of blast cells in peripheral blood- 0, 1-2, >2. Wt1 expression was lowest in the 1st group, and the highest in the 3rd group((p Conclusion. Wt1 expression is elevated in the majority of pts with PMF as well as in secondary MF. Correlation was found with blast level and spleen size. Wt1 could be used for monitoring efficacy of ruxolitinib therapy Disclosures Konopleva: Reata Pharmaceuticals: Equity Ownership; Abbvie: Consultancy, Research Funding; Genentech: Consultancy, Research Funding; Stemline: Consultancy, Research Funding; Eli Lilly: Research Funding; Cellectis: Research Funding; Calithera: Research Funding. |
