Why this matters
While trying to avoid COVID-19 infection, patients ultimately diagnosed with multiple myeloma may have delayed interactions with healthcare professionals and consequently delayed their cancer diagnosis.
Researchers collected data on newly diagnosed patients with multiple myeloma from January 2019 until July 2021 across five institutions (three universities and two hospitals) in England. In total, 323 patients with multiple myeloma were identified.
Patients were divided into two groups: those diagnosed between Jan. 1, 2019, until Jan. 31, 2020, or pre-COVID, and those diagnosed from Feb. 1, 2020, to July 31, 2021, or post COVID.
Among all patients, 80 (24.8%) were diagnosed with smoldering multiple myeloma and 243 (75.2%) were diagnosed with multiple myeloma requiring treatment.
Significantly more patients in the post-COVID group were diagnosed with myeloma through the emergency route (45.5% post COVID vs. 32.7% pre-COVID; P = .03).
Clinical complications leading to emergency admission prior to a myeloma diagnosis also differed between the two cohorts:accounted for most emergency admissions in the pre-COVID cohort while skeletal-related events, including spinal cord compression, were the major causes for diagnosis through the emergency route in the post-COVID cohort.
Patients who were diagnosed with symptomatic myeloma pre-COVID were more likely to be treated with a triplet rather than doublet combination compared with those diagnosed in the post-COVID period (triplet pre-COVID 79.1%, post COVID 63.75%; P = .014).
Overall survival at 1 year was not significantly different between the pre-COVID and post-COVID groups: 88.2% pre-COVID, compared with 87.8% post COVID.
Overall, the authors concluded that the COVID pandemic “resulted in a shift in the symptomatology, disease burden, and routes of diagnosis of patients presenting with myeloma” and “this may have significant consequences” over the long term.
The study does not provide a clear time frame of delays in diagnosis.
The study authors did not report any conflicts of interest.
