ASH 2020: Mayo’s Dr. Vincent Rajkumar Chooses His Top 5 #ASH20 Myeloma Abstracts

Each year a group of the top myeloma specialists review the abstracts presented at the American Society of Hematology and pick their favorites.  This has been so helpful to all those of us who attend this annual meeting.  It is so overpowering for a patient, patient advocate, or health care professionals to whittle down the avalanche of information into manageable segments which are most relevant to the myeloma care community.  

And each year Dr. Mike Thompson has been so kind as to tabulate the picks from the myeloma specialists into a easily understandable table.  Dr. Thompson will be completing this work in next few days, and at that time Myeloma Crowd will be publishing this document. In addition, some of these myeloma specialists have gone the extra step, and provided an excellent explanation as to why they have chosen their most important TOP FIVE.  

Dr. Vincent Rajkumar has been doing this for several years, and he has again this year.  Each year he has chosen to list his favorites, but only those abstracts which have not been reported on previously.  This is his list of the most significant new initiatives for #ASH20.  As in the past, he left out many great studies where similar results were already presented or published before. And his focus was for clinical relevance, impact, and methodology.
