How do you interpret CSF pleocytosis in the context of significant leukocytosis on CBC?
There is no correction factor as there would be for CSF vs serum glucose, for example. A patient with leukocytosis in peripheral blood, for example, due to urosepsis would not always have elevated CSF WBC unless there were concomitant meningoencephalitis. I would consider 100 WBC abnormal for CSF re...
What is your strategy for optimizing hydroxyurea dosage in patients with symptomatic sickle cell disease, particularly for genotypes HbSS and HbS/Beta thal?
I am far, far more worried about underdosing than overdosing. Although HgF is the traditional lab parameter, it may not go up in all patients. I also look for a decrease in reticulocytes, LDH, indirect bili (less hemolysis), less inflammation (WBC and platelets), and a lowering of MCHC (i.e., fewer ...

How do you approach severe anemia and thrombocytopenia in an elderly patient whose bone marrow biopsy shows hypercellular marrow with mild dysplasia in erythroid and megakaryocytic lineage but normal cytogenetics and a negative NGS panel?
This is a really interesting case! Few things to consider: The presence of a small PNH clone suggests marrow injury however, the marrow is usually hypo rather than hypercellular in this scenario. It may be worthwhile to send HLA typing. The presence of HLA-B14:02, HLA-B40:02, and HLA-B07:02 alleles...

Which patients with smoldering myeloma do you treat?
Let me address the last comment regarding treatment of high risk smoldering myeloma. IF one thinks that the patient requires treatment for myeloma, why treat with a regimen that is NOT the preferred treatment for myeloma? For example, lenalidomide alone or lenalidomide/dexamethasone. If this were "a...

How do you evaluate a patient with MGUS and peripheral neuropathy?
When I see a patient with MGUS and peripheral neuropathy, I think about it in stages: Does the patient have an IgM-monoclonal gammopathy? If so, then I think about DADS-M. An EMG/NCS, anti-MAG antibody, PET scan, and bone marrow biopsy are generally all part of the workup. I try to do MYD88 testing...

For patients with metastatic poorly differentiated large cell neuroendocrine carcinoma of the lung, do you typically use NSCLC or SCLC regimens?
Earlier Studies have shown controversial results. Some show that small cell lung cancer-based regimen concluded better outcome; however, more recently, gemcitabine-platinum therapy in specific and NSCLC-based regimens led to a better outcome.We reported a retrospective study showing no statistically...
