RB1 (13q14 del) is found in about 50% of CLL/SLL cases and is usually associated with a predominantly mutated IgVH gene status and a favorable response to chemotherapy. IGH/CCND1 t(11;14) stratifies patients as likely mantle cell lymphoma (MCL) and is usually associated with an unfavorable response to chemotherapy. p53 (17p13) monosomy is usually associated with an unfavorable response to chemotherapy.
