Are signal transducer and activator of transcription 3 ( STAT3 ) gene polymorphisms associated with treatment outcomes in acute myeloid leukemia? Context: In the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway, STAT3 is one of the most prominent prognosis factors for cancer and leukemia. STAT3 activation might promote cellular transformation and therefore have an important role in human tumors. This study aimed to investigate the relationship between STAT3 polymorphisms and treatment response of acute myeloid leukemia (AML) in the Chinese population. Three single-nucleotide polymorphisms (SNPs) were tested in 130 patients with AML. Genomic DNA was isolated from peripheral blood and assayed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The results of response to chemotherapy showed that there were strong relationships between unfavorable cytogenetics, partial remission (and even no remission), and GG genotype frequency in rs9909659 (P = 0.01 and 0.03). Patients younger than 45 years were associated significantly with GA/AA genotype (P = 0.01).

The results of this study suggest that the GG genotype in rs9909659 might confer increased resistance to standard chemotherapy. Final Decision: yes
