ABSTRACT
OBJECTIVE@#To investigate the clinical characteristics of myelodysplastic syndrome (MDS) with TP53 mutant and the relationship between TP53 mutation and monosomal karyotype in MDS patients.@*METHODS@#The TP53 mutations in 102 patients with de nove MDS were retrospectively analyzed, and the clinical features of the TP53 mutation group and the non-mutation group were compared. The relationship between TP53 mutation and karyotype, especially monosomal karyotype was analyzed.@*RESULTS@#Fifty-two out of the 102 MDS patients were male and 50 were female, the median age was 59.5 (23-83) years old. The mutational frequency of TP53 was 12.7%, which mostly occurred in patients with MDS-EB. As compared with non-mutation group, the hemoglobin level and platelet count were lower (P=0.001, P=0.033), the LDH level and bone marrow blast ratio were higher in TP53 mutation group (P=0.002, P<0.001), but the statistical difference of alsolute count of neutrophils and levels of serum ferritin and β2-microglobulin between 2 groups was not found. The karyotype abnormality frequency of patients with TP53 mutation was 90.9%, among them 72.7% was monosomal karyotype. The incidence of monosomal karyotype in the TP53 mutation group was very significantly higher than that in the non-mutation group (P<0.001). MDS with TP53 mutation and monosomal karyotype appeared in the groups with high and very high IPSS-R risk.@*CONCLUSION@#MDS patients with TP53 mutation have unique clinical features and high incidence of monosomal karyotype, and their overall prognosis is poor.
