To highlight the role of azacytidine (AZA) in patients with myeloproliferative neoplasms developing blast phase (MPN-BP), we evaluated retrospectively 19 patients [M/F 15/4, median age 71.3 years, interquartile range (IQR) 64.5-77.7] reported in the database of our cooperative group. Median time from diagnosis to BP evolution was 52.7 months (IQR 11.2-181.8). All patients were treated with AZA at the standard dosage of 75mg/m(2). Two patients died early after 5-AZA initiation from pulmonary fungal infection and respiratory failure respectively, 4 patients had a disease progression, 4 patients a stable disease, 3 patients had an hematological improvement, 1 patient a partial response and 5 pts (26.3%) a complete response (CR) after 4, 4, 4, 5, and 12 months. The median cumulative survival from BP evolution was 9.9 months (95%CI 6.6-13.1): the comparison with an historical cohort of 72 patients with MPN-BP treated with approaches other than AZA (median cumulative survival 3.1 months, 95%CI 1.1-5.0) showed a significant advantage for patients treated with AZA (p=0.02). Our data confirm the relative efficacy and safety of AZA in this group of patients with otherwise dismal prognosis, underlining the possible achievement of long-lasting responses in a sizeable portion of them.

Abstract

To highlight the role of azacytidine (AZA) in patients with myeloproliferative neoplasms developing blast phase (MPN-BP), we evaluated retrospectively 19 patients [M/F 15/4, median age 71.3 years, interquartile range (IQR) 64.5-77.7] reported in the database of our cooperative group. Median time from diagnosis to BP evolution was 52.7 months (IQR 11.2-181.8). All patients were treated with AZA at the standard dosage of 75mg/m(2). Two patients died early after 5-AZA initiation from pulmonary fungal infection and respiratory failure respectively, 4 patients had a disease progression, 4 patients a stable disease, 3 patients had an hematological improvement, 1 patient a partial response and 5 pts (26.3%) a complete response (CR) after 4, 4, 4, 5, and 12 months. The median cumulative survival from BP evolution was 9.9 months (95%CI 6.6-13.1): the comparison with an historical cohort of 72 patients with MPN-BP treated with approaches other than AZA (median cumulative survival 3.1 months, 95%CI 1.1-5.0) showed a significant advantage for patients treated with AZA (p=0.02). Our data confirm the relative efficacy and safety of AZA in this group of patients with otherwise dismal prognosis, underlining the possible achievement of long-lasting responses in a sizeable portion of them.
