Has the combination of daratumumab, bortezomib, and dexamethasone been tried for the treatment of plasma cell leukemia?
Do you ever discontinue ibrutinib in patients with CLL who have a good response?
For patients who are responding well to ibrutinib and tolerating the drug well, I do not discontinue ibrutinib. The clinical trials of single agent BTK inhibitors have all continued therapy indefinitely, which is a logical approach considering that very few will attain minimal residual disease negat...
Does rituximab + lenalidomide have a role in advanced follicular lymphoma?
There has been much interest in replacing traditional chemo-immunotherapy (generally R-bendamustine, R-CHOP or R-CVP) with noncytotoxic therapy such as rituximab plus lenalidomide in patients with previously untreated advanced stage follicular lymphoma. Studies in relapsed/refractory patients have s...
Is there any role for post chemotherapy (R CHOP x 6) radiation therapy after a splenectomy for a stage IE diffuse large B-cell lymphoma involving only the spleen?
Quite an interesting presentation in terms of extranodal site and age. I would say no for consolidative RT here. For Lugano PET CR after R-CHOPx6, the added benefit of ISRT in a young patient is low and counterbalanced by a real long term 2nd malignacy risk. Other than bulky >7.5cm sites, 'special' ...
What is the optimal regimen for advanced stage Nodular Lymphocyte Predominant Hodgkin Lymphoma?
I do not believe that there is an "optimal" chemotherapy regimen for advanced nodular lymphocytic predominant Hodgkin lypmhoma. The most commonly used regimen is probably ABVD +/- rituximab. CHOP-R might be a good choice when the question of early transformation to diffuse large B-cell lymphoma is s...
What is the preferred regimen for testicular lymphoma with de novo symptomatic CNS involvement and systemic disease at the time of presentation ?
I often consider treating with high dose methotrexate alternating with R-CHOP in such cases. At the end of treatment, I consider radiation to the contralateral testicle. Others have treated similar patients with Hyper-CVAD (Park et al. Am J Hematology 2007)
For multiple myeloma patients with vertebral lesions requiring palliative radiation (e.g. 20-30 Gy in 10fx), do you treat concurrently with modern systemic myeloma agents such as lenalidomide and bortezomib?
We found in an institutional retrospective experience that patients with MM can safely be treated with lenalidomide, bortezomib, and cytotoxic therapy with palliative xrt.https://www.ncbi.nlm.nih.gov/pubmed/25176474
How would you approach a chronic phase CML patient who is responding to second generation TKI but not yet in molecular remission and is now pregnant?
If the patient is now pregnant, I would stop the TKI immediately, and initiate therapy with interferon. If that is not tolerable, I'd recommend hydroxyurea, although it will likely not control relapse into overt chronic phase.
For male patients in chronic phase CML on a TKI and not yet in a MMR, is there a preferred amount of time spent in a MMR before discontinuing TKI therapy to conceive or bank sperm ?
Hard to answer this one. My preference would be that the patient be in MMR confirmed by two readings three months apart before experiencing a dose interruption.
What is your approach to the upfront treatment of anaplastic large cell lymphoma, ALK positive, with low IPI score in a young person?
ALK positive ALCL is the most responsive of the aggressive PTCL’s to chemotherapy, and the majority of young patients can be cured with an anthracycline containing chemotherapy regimen. Either CHOP or CHOEP (ie CHOP plus etoposide) are frequently used. In a young healthy patient I favor CHOEP based ...
