ABSTRACT
Objective:
To analyze the risk factors of thrombosis in patients with JAK2V617F mutation positive myeloproliferative neoplasms (MPN).Methods:
A total of 223 MPN patients with JAK2V617F mutation in the Second Hospital of Tianjin Medical University from September 2017 to May 2023 were retrospectively enrolled, including 111 males and 112 females, aged [M(Q1,Q3)] 57(21,66) years. According to the presence or absence of thromboembolism during follow-up, the patients were divided into thrombosis group (n=102) and non-thrombosis group (n=121). The clinical characteristics, laboratory characteristics, cytogenetics and other disease progression and survival of the two groups of patients were analyzed. As of March 31, 2023, the follow-up period [M (Q1, Q3)] was 6 (3, 10) years. The influencing factors of thrombosis in JAK2V617F positive MPN patients were analyzed by using the Cox risk model.Results:
Among 223 JAK2V617F positive MPN patients, 144 were polycythemia vera (PV), 51 were essential thrombocythemia (ET) and 28 were primary myelofibrosis (PMF). The mutation rates of ASXL1 and BCORL1 genes in the thrombosis group were 19.6% (20/102) and 6.9% (7/102), respectively, which were higher than those in the non-thrombosis group [9.1% (11/121) and 0.8% (1/121)] (both P<0.05). The proportion of monocytes, C-reactive protein (CRP), interleukin-1ß (IL)-1ß, IL-8 and tumor necrosis factor-ß (TNF-ß) increased in the thrombosis group were higher than those in the non-thrombosis group (all P<0.05). Multivariate analysis showed that age≥60 years (HR=2.132, 95%CI 1.376-3.303, P=0.001), history of thrombosis (HR=3.636, 95%CI 2.121-6.202, P<0.001), ASXL1 mutation positive (HR=2.245, 95%CI 1.093-3.231, P=0.022) and elevated TNF-ß (HR=2.009, 95%CI 1.113-3.624, P=0.021) were risk factors for thrombosis in JAK2V617F positive MPN patients.Conclusions:
In addition to age, history of thrombosis and positive ASXL1 mutation, elevated TNF-ß is also an influencing factor of thrombosis in JAK2V617F positive MPN patients. Intervention of inflammation may have a certain effect on the prevention and treatment of thrombosis.
