Yes, he should get rituximab. His prolonged neutropenia is more likely due to the previous bendamustine than the rituximab, and I don’t think his risk will be increased much, if at all, if re-treated with rituximab in this scenario.

Regarding the neutropenia, I believe it’s most likely due to bendamustine, not rituximab, which can cause prolonged lymphopenia. Therefore, I would indeed restart rituximab as part of the new chemo regimen.

The prolonged neutropenia was more likely from the bendamustine, not the rituximab. I would have no hesitation in using rituximab again. Unlike bendamustine, rituximab is not a stem cell poison.

We reported, as an abstract, our experience with close to two dozen cases of rituximab neutropenia. Several patients received rituximab again (a couple again and again), and every patient relapsed (generally about 90 days). I am not aware of whether or not there would be cross-reactivity of this reaction with other anti-CD20 antibodies, but I suspect there would be.

I would use rituximab retreatment and combine with ifosfamide, carboplatin, and etoposide, and try to reach an autologous bone marrow transplant.
