Predictors of treatment response and survival outcomes in patients with advanced cardiac AL amyloidosis.

ABSTRACT: Patients with advanced cardiac immunoglobulin light chain (AL) amyloidosis have a poor prognosis. Early hematologic and cardiac responses can prolong survival, but predictors of these outcomes have yet to be clarified. We report on 142 patients with newly diagnosed stage IIIb AL amyloidosis. After a median follow-up of 60 months, the median overall survival (OS) was 9 months. Independent baseline factors associated with shorter OS were symptom onset to diagnosis >6 months (hazard ratio [HR], 1.94; P = .003); bone marrow plasmacytosis ≥ 10% (HR, 1.98; P = .01); troponin I > 0.635 ng/mL (HR, 1.62; P = .04); New York Heart Association class III or IV (HR, 1.67; P = .04); and 6-minute walk test distance < 200 m (HR, 1.85; P = .01). Early hematologic (within 1 month) and cardiac (within 3 month
