Treatment of Multiple Myeloma: ASCO-Ontario Health (Cancer Care Ontario) Living Guideline.

Abstract

To provide updated guidance regarding the therapy for multiple myeloma. ASCO and Ontario Health (Cancer Care Ontario) convened a joint Expert Panel and conducted an updated systematic review of the literature. The updated review identified a total of 161 relevant randomized trials. Daratumumab therapy may be offered to patients with high-risk smoldering myeloma. Quadruplet therapy with daratumumab or isatuximab, combined with bortezomib, lenalidomide, and dexamethasone, should be offered as initial therapy for transplant eligible patients. They should also be offered at least lenalidomide maintenance, with or without daratumumab, carfilzomib, and/or dexamethasone. Quadruplet therapy with daratumumab or isatuximab, combined with bortezomib, lenalidomide, and dexamethasone, should be offered as therapy for suitable transplant-ineligible patients. Patients with relapsed or refractory multiple myeloma should be offered triplet therapy or T-cell redirecting therapies according to a set of recommended principles.Additional information is available at www.asco.org/hematologic-malignancies-guidelines.
