#ISA2020 Yesterday: Plenery Session on Diagnosis and Management of AL #amyloidosis chaired by @awechalekar and Stefan Schönland. Here is my take home message @AmyloidosisSupp @Amyloidosisfdn @Amyloidosis_ARC @AmyloidC @MayoAmyloid @amyloid_papers
@ADispenzieri talked about Diagnosis and work-up. Fat pad biopsy and bone marrow biopsy are able to determine the diagnosis of AL in 50-79%. In those cases an organ biospy is not necessary 
@ADispenzieri at #ISA2020: 10 % of patients with Congo Red+ amyloid detection have TTR Amyloidosis and elevated FLC--> you need to determine the diagnosis by mass spec or IHC
@ADispenzieri at #ISA2020: Clinical presentation of AL is very heterogenous --> look for the "Doors to amyloidosis diagnosis" with symptoms such as spinal stenosis, hepatomegaly or pseudoclaudication
Dr Hegenbart at #ISA2020 pointed out RED FLAGS 🚩for AL #amyloidosis and suggested NT-proBNP for all patients with MGUS and elevated Free Light Chins. NT-proBNP can detect cardiac involvement before symptoms of heart failure occur in 20% of patients.
Dr Kastritis presented at #ISA2020 data to use Growth Differentiation Factor-15 (GDF-15) as an independent prognostic marker for survival and renal outcomes in (AL) Amyloidosis
Dr Schönland at #ISA2020 t(11;14) is a negative prognostic marker for AL patients treated with bortezomib but a positive prognostic marker for patients receiving ASCT 🤔ASCT for all patients with t(11;14)?
Dr Schönland at #ISA2020 cytogenetic aberration impact prognosis in AL --> 1q21 gain has poorer prognosis in AL similar to MM. In t(11;14)consider venetoclax ASAP
Dr Palladini at #ISA2020 stated that decrease in IVS does not correlate with OS--> and should not ne used for organ response!
Dr Palladini at #ISA2020 summarised the goal for hematologic response--> Goal should be dFLC 10 or iFLC 20. Do not use FLC ratio in AL Amyloidosis
