Detection of fms-like tyrosine kinase 3 (FLT3) and nucleophosmin 1 (NPM1) mutations from formalin fixed paraffin embedded marrow tissues in patients with myeloid neoplasms /
Acute myeloid leukemia (AML) and myeloproliferative neoplasms (MPN) are the most common entities of myeloid neoplasms. In AML, among the most frequent genetic alterations that carries both diagnostic and prognostic values are mutations in Nucleophosmin 1 (NPM1) and FMS-like tyrosine kinase 3 (FLT3)...

| 520 | |a Acute myeloid leukemia (AML) and myeloproliferative neoplasms (MPN) are the most common entities of myeloid neoplasms. In AML, among the most frequent genetic alterations that carries both diagnostic and prognostic values are mutations in Nucleophosmin 1 (NPM1) and FMS-like tyrosine kinase 3 (FLT3) genes. Nevertheless, their frequencies among AML patients in Kuantan, Pahang have not been studied. Additionally, published literatures on both of these mutations in MPN are scarce although they have been shown to confer MPN in animal model. This cross-sectional study therefore aimed to determine the proportion of FLT3-ITD, FLT3-D835 and NPM1 mutations among patients diagnosed with AML and MPN in Hospital Tengku Ampuan Afzan of Kuantan, Pahang from the year 2016 to 2019. A total of 56 cases were studied, of which 43 cases were AML and 13 cases MPN. Molecular methods employed were polymerase chain reaction-based assays for mutation detection, from the retrieved trephine biopsy tissue blocks. The mutation positivity was subsequently validated by Sanger DNA sequencing. Six of the 43 cases (14.0%) of AML were positive for FLT3-ITD and a similar proportion (6/43, 14.0%) were also positive for NPM1 mutations. FLT3-D835 mutation was identified in three of the AML cases (7.0%) while concurrent mutations of NPM1 and FLT3-ITD were seen in two of the mutation positive cases (4.7%). One of the 13 (7.7%) MPN cases was positive for FLT3-ITD. None of the MPNs cases were positive for either FLT-D835 or NPM1 mutations. When the mean haematological values were compared with the mutation status in AML cases, only the total white cell count was significantly higher with FLT3 mutations (p=0.001). In conclusion, the frequency of FLT3 mutations in the AML cases concurs with others, while the frequency of NPM1 mutations in our study was relatively lower as compared to other reports. The significance of the FLT3-ITD mutation positivity found in our series of MPN remains to be elucidated. | ||
