TET2 and angioimmunoblastic T-cell lymphoma: Although there was a trend that AITL patients with the pathogenic TET2 mutations detected in the BM/PB had a worse clinical outcome, no statistically significant differences in the second hematologic malignancy-free survival were observed (p-value=0.3273, stratified hazard ratio [HR] = 0.29), consistent with the literature (Lemonnier et al., 2012).
