Patients diagnosed with prostate cancer during the first year of the COVID-19 pandemic in the United States were more likely to have higher-risk disease and less likely to receive definitive treatment than patients diagnosed before the pandemic, according to the findings of separate studies presented at the American Urological Association’s 2023 Annual Meeting.
“The COVID-19 pandemic was associated with significant changes in the distribution of both stage and grade of prostate cancer,” Edoardo Beatrici, MD, of Brigham and Women’s Hospital in Boston, Massachusetts, and colleagues concluded in a poster presentation. “Possible explanations for this migration include a better selection of patients for prostate biopsy during the pandemic or changes in prostate cancer screening patterns.”1
Using the National Cancer Database, the investigators identified 398,719 men diagnosed with prostate cancer from 2018 to 2020. The patients were divided into a pre-pandemic (2018-2019) group (n=281,602) and a pandemic (2020) group (n=117,117).

Compared with the pre-pandemic group, the pandemic group had 15% higher odds of metastasis, 3% higher odds of grade group 4 or 5 disease, and 15% higher odds of D’Amico intermediate- and high-risk disease after adjusting for multiple variables. In addition, the pandemic group had 6% higher odds of having PSA levels above 20 ng/mL and 12% higher odds of cT3-4 stage disease.
In a separate study of the same patient populations, Dr Beatrici and colleagues compared the likelihood of definitive treatment between the study periods according to grade group.2 Among patients with grade group 1 and 2 disease, patients in the pandemic cohort had 20% and 15% lower odds of treatment, respectively, compared with their counterparts in the pre-pandemic cohort in adjusted analyses.
Among patients with grade group 3 disease, those in the pandemic cohort had 13% lower odds of treatment. The investigators found no significant difference between the cohorts among patients with grade group 4 or 5 disease.
During the first year of the pandemic, patients with grade groups 1, 2, and 3 prostate cancer were more likely to receive expectant management (such as active surveillance or watchful waiting) than definitive treatment, although this was not the case for patients with more aggressive disease.
“This finding suggests a high capacity of facilities to appropriately risk stratify and prioritize higher-risk cases during a public health emergency,” the investigators wrote.
