It usually carries a dismal prognosis and represents an unmet need for novel therapeutic interventions. We report a case of an 80-year-old male who developed double-hit (DH) RT with translocations of MYC and BCL6 after 5 years of watchful waiting for standard-risk CLL. He was treated with induction therapy consisting of 4 cycles of anthracycline-based chemoimmunotherapy (CIT) and 2 cycles of platinum-based CIT with intrathecal methotrexate for CNS prophylaxis followed by continuous maintenance therapy with ibrutinib. He achieved complete remission after the induction therapy. At the time of writing, four and a half years after the diagnosis with DH-RT, he remains in complete remission without evidence of RT or CLL. The novel therapeutic approach used in successful treatment of this patient should be further explored.Keywords: Richter transformation, RT, chronic lymphocytic leukemia, CLL, double hit lymphoma, ibrutinib maintenance |
