Would you consider retreatment with bendamustine/rituximab (BR) therapy in this patient?

 

Once chemoimmunotherapy has failed in a patient who has a very short period to next therapy, the use of chemoimmunotherapy produced rather low outcomes. Classically, it is said that the rate of response is always 50% of the one achieved as front-line. In this case, considering the short time to relapse, the use of chemoimmunotherapy is not recommended, but rather the use of BCR inhibitors, such as ibrutinib or idelalisib plus rituximab.

Case 2: Relapsed and Refractory CLL

James S. is a 67-year-old college professor from Ithaca, New York; he is a Vietnam veteran with a history of treatment for Agent Orange exposure; his history is also notable for prior smoking (15-pack year) and mild COPD.

  • In November 2013, he presented to his PCP for a routine physical; his examination showed mild lymphadenopathy and his CBC showed evidence of lymphocytosis (lymphocytes 6 x 109/L); he was referred to an oncologist for further diagnostic evaluation.

  • Differential diagnosis showed B-cell CLL, with absolute lymphocytosis (19,000/mm3) and flow cytometry positive for CD5 and CD23.

  • Interphase cytogenetic analysis showed no deletion of 17p.

  • The oncologist initiates treatment with bendamustine/rituximab (BR) and James shows improvement in hematologic parameters after 6 cycles.

  • James was out of the country at a meeting, and he failed to return for a scheduled follow-up appointment in January 2015.

In March 2015, he presented to his oncologist with symptoms of unintentional weight loss over the past 2 months (>10%), severe fatigue (interfering with work), and dyspnea; his CBC is consistent with worsening anemia and thrombocytopenia.

  • CT scan shows evidence of extensive abdominal lymph node recurrence.

  • At the time of his recurrence, James’s ECOG performance status was 2, and liver and kidney functioning were within normal limits.
