Abstract
TCL-1 expression is variable in CLL, and no study has examined its association with treatment response. We measured TCL-1 protein in CLL cells from 51 patients who then received pentostatin, cyclophosphamide, and rituximab. TCL-1 expression did not correlate with any pre-treatment characteristics. Lower TCL-1 levels were associated with higher probability of attaining flow cytometry-negative status post-treatment (52% versus 17%, p = 0.046). Trends toward improved complete remission rate (49% versus 19%, p = 0.064) and progression-free survival (medians: 33 versus 20 months, p = 0.199) were noted with lower TCL-1 expression. These data suggest TCL-1 expression may help predict treatment outcome in CLL patients following chemoimmunotherapy, and examination in larger studies is warranted.
