INRTODUCTION : The International Myeloma Working Group (IMWG) developed the frailty index (IMWG-FI) to predict the toxicity and mortality risk faced by elderly patients with multiple myeloma. However, due to the time-consuming nature and subjectivity of IMWG-FI, alternative frailty assessment tools have been developed to reduce subjectivity and enhance the ability to identify frailty. O BJECTIVE (S) To assess the consistency of various frailty assessment tools in elderly patients with multiple myeloma and their predictive efcacy for patients survival. M ETHOD (S) We systematically assessed 84 newly diagnosed multiple myeloma patients aged≥60 years old using various frailty assessment tools, including the IMWG frailty index (IMWG-FI), Mayo frailty score, simplied IMWG frailty index(IFM), and British Myeloma Research Alliance Risk (MRP) score. We compared progression-free survival (PFS) and overall survival (OS) outcomes based on these different assessment tools. For the purpose of analysis, we combined patients categorized as Fit or Intermediate Fit into a single group called Non-Frail.
