Background: MM is the second most common hematologic malignancy, which despite significant therapeutic advancements, remains incurable. The complexity of MM and its intricate management creates substantial informational demands for patients navigating their care.

Methods: A cross-sectional survey study (Mayo Clinic IRB # 25-004671) was conducted to assess MM patients’ awareness about disease basics. A voluntary English language survey (47 questions) encompassing multiple domains of patient MM awareness was administered (REDCap) via the patient EMR portal (Mayo Clinic) and MM support groups nationally. Responses were analyzed using descriptive and inferential statistics (R; Bluesky Statistics, V 10.3.4). Multiple model logistic regression was used for multivariate analysis using age (≤70 or >70 yrs), gender, education (high school or less vs bachelor's and above), income (≤$74999 vs ≥$75000) and insurance status (private vs public).

Results: The survey was completed by 2353 patients (pts) with 2177 MM (83.4% active, 16.6% smoldering) and 176 MGUS. Among MM pts median age was 63 yrs with 52.5% males, 91.5% white and 95.7% non-Hispanic. 17.5% had a prior diagnosis of MGUS and 20.2% of smoldering MM prior to MM, and 79.5% were not aware of MM prior to their own diagnosis. Majority (77%) depended most on their doctors to gain MM information but 24.3% reported not having sufficient discussion about MM at diagnosis. 31.2% were not sure what type of MM they had, 22.9% could not correctly report the cell of MM origin (plasma cell), 40.6% did not receive MM stage information at diagnosis, 45.4% were either unsure or reported wrong risk factors for MM and 22% were unsure or mistaken about MM symptoms. Majority (62.9%) did not understand genetic risk categories of MM, 32.3% did not report adequate understanding of MM tests and 31.9% did not understand the difference between response and remission. 57.5% reported not understanding about MRD status and 57.1% never had MRD testing. Majority (86.8%) felt they got adequate opportunity to participate in treatment decisions but only 54.2% felt confident in managing MM with their current knowledge and 28.2% had not discussed their prognosis although 77.7% wanted to know about it. Majority (64.4%) felt they had knowledge gaps about MM and its management. Multivariate analysis showed that females were less likely (OR 0.67) while those with public insurance were more likely (OR 1.35) to report receiving adequate information at diagnosis. Older pts (OR 0.55), males (OR 0.43), with lower education (OR 0.5), lower income (OR 0.5) and public insurance (OR 0.72) were less likely to identify the cell of MM origin correctly. These same groups were significantly less likely to be aware of types of MM as well. Older pts (OR 0.73), with lower education (OR 0.6), lower income (OR 0.77) and public insurance (OR 0.76) were less likely to be aware of MM genetic risk categories. Females (OR 0.81), with lower education (OR 0.68) and lower income (OR 0.63) were less likely to understand MM lab tests. Females and those with lower income were significantly less likely to report receiving adequate information about treatment options. Females reported that they did not get adequate opportunities to participate in treatment decisions (OR 0.65). Older pts, and those with lower income, lower education or public insurance were less likely to understand minimal residual disease (MRD) and all these groups were less likely to have had MRD testing. Those with lower income (OR 0.75) and lesser education (OR 0.72) felt less confident in managing MM with current knowledge. Older pts, females and those with lesser education, lower income and public insurance were also significantly less likely to have discussed about MM prognosis.

Conclusion: This study demonstrates substantial basic knowledge deficits integral to managing and prognosticating MM among patients. Patients from unfavorable sociodemographic-economic groups were more likely to have awareness gaps and report lack of information which is integral to having adequate understanding of MM being provided to them. These findings highlight the critical need for structured, comprehensive educational interventions that address fundamental disease concepts to empower pts, overcome healthcare disparities, and engage pts in shared decision-making.
