ROR1 is, however, expressed in hematologic malignancies and solid tumors, such as chronic lymphocytic leukemia (CLL) [10,11], mantle cell lymphoma (MCL) [12], diffuse large B-cell lymphoma (DLBCL) [13,14,15], melanoma [16,17,18,19,20,21,22], and NSCLC [17,23]. This evidence concerns the gene ROR1 and mantle cell lymphoma.
