Currently, in the absence of information about the pathways in which lnc-IRF2-3 and lnc-KIAA1755-4 participate in CLL cells, as well as their potential interactions, it is hard to speculate whether the two lncRNAs affect TTFT and OS synergistically or independently of each other. This evidence concerns the gene KIAA1755 and B-cell chronic lymphocytic leukemia.
