Immunohistological studies can give more information. Need more info like blood cell counts. ...Read more

Chronic anemia: The main reason to repeat the marrow biopsy would be if there was a change in your disease- more refractory, more wbc, lower plts, etc. If the underlying chronic disease cannot be treated or is unknown, then using EPO to treat and monitoring hgb is quite reasonable management. But it sounds like you may wish to have more explanation. Making and apmt to talk or ask questions is OK, or consult here. ...Read more

Bone marrow biopsy/aspiration (chronic cytopenias/fatigue) f/u appt delayed 4 karyotyping. Is that usually to check CML or what else is possible? Thx

Bone marrow biopsy/aspiration (chronic cytopenias/fatigue) f/u appt delayed 4 karyotyping. Is that usually to check CML or what else is possible? Thx

Karyotype important: There are many things that cause low counts. CML isn't one of them - that causes high counts. Getting the genetic testing is very important for making an accurate diagnosis no matter what the diagnosis. I always make my patients wait for that before they come in for their follow-up appointment. I know it's hard to wait, but it's better to get the full and accurate picture all at once. ...Read more
