Treatment of Multiple Myeloma: ASCO-OH (CCO) Living Guideline

Dr. Lisa Hicks and Dr. Joseph Mikhael discuss the updated guideline from ASCO and Ontario Health (Cancer Care Ontario) on the treatment of multiple myeloma. They cover recommendations for therapeutic options across smoldering multiple myeloma, transplant eligible multiple myeloma, transplant ineligible multiple myeloma, and relapsed or refractory multiple myeloma. They highlight the importance of shared decision making and patient-centric care. They comment on the explosion of new treatment options in this space and the impetus for this guideline becoming a living guideline, which will be updated on an ongoing, regular basis.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I am interviewing Dr. Lisa Hicks from St. Michael's Hospital and University of Toronto, and Dr. Joseph Mikhael from the Translational Genomics Research Institute, an affiliate of City of Hope Cancer Center, co-chairs on "Treatment of Multiple Myeloma: American Society of Clinical Oncology-Ontario Health (Cancer Care Ontario) Living Guideline."

Thank you for being here today, Dr. Hicks and Dr. Mikhael.

Dr. Lisa Hicks: Thanks so much.

Dr. Joseph Mikhael: It is a pleasure to be with you, Brittany. Thank you.

Brittany Harvey: Before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Hicks and Dr. Mikhael who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

Dr. Joseph Mikhael: It is amazing when we think back in myeloma years, 2019 actually seems a very, very long time ago because really so much has changed in myeloma over these last six to seven years. Indeed, there have been over 150 randomized controlled trials that we didn't have at the prior guideline that we reviewed for this. Myeloma is a disease that has really changed so dramatically over these last several years. Multiple new agents have been introduced. We now have CAR-T cell therapy, bispecific antibodies, and multiple other agents that were not available at the time.

Furthermore, with this growing complexity, it is becoming more important than ever to be able to provide practical advice and guidelines to the oncology community. For most oncologists, they have less than 5% o
