Next, we analyzed the effects of BCL11B in combination with TCF1 on prognosis, compared with those who were TCF1highBCL11Bhigh, CLL patients who were TCF1lowBCL11Blow had a poorer TTFT and OS (Figures 4D, E, left panel) as well as shorter RMST (Figures 4D, E, right panel). The gene discussed is BCL11B; the disease is B-cell chronic lymphocytic leukemia.
