ABSTRACT
INTRODUCTION AND OBJECTIVE: In 2018, The US Preventive Services Task Force (USPSTF) changed its recommendations for prostate specific antigen (PSA) screening from "non-recommended" to "shared decision-making among men aged 55-69". Thereafter, COVID-19 Pandemic disrupted cancer care with evidence suggesting overall reduced access to and utilization of health care services including preventive screening. We aim to examine the impacts of both events on PSA screening for men aged 55-69. METHOD(S): We analyzed 2013, 2015, 2018, 2019, and 2021 National Health Interview Survey data. Men >54 who reported PSA testing within 12 months preceding survey were considered to have undergone screening. Adjusted difference in differences (DID) analyses were performed to compare changes in screening in men aged 55-69 with reference to men >70 between 2015 and 2019 (pre- and post- 2018 USPSTF recommendation) and between 2019 and 2021 (pre- and post-Pandemic). RESULT(S): A total of 24,308 men were included. PSA screening prevalence was 35.4% (95%CI: 33.7%, 37.1%), 32.1% (95%CI: 30.3%, 33.9%), 33.3% (95%CI: 31.6%, 34.9%), 37.2% (95%CI: 35.7%, 38.8%), and 34.9% (95%CI: 33.3%, 36.5%) respectively for included years. From 2015 to 2019, PSA screening increased 4.6% among men aged 55-69 (95%CI: 1.7, 7.5%) and increased 6.5% among men >70 (95% CI: 2.7, 10.4%). From 2019 to 2021, PSA screening decreased 3.1% among men aged 55-69 (95%CI: 0.58%, 5.8%);PSA screening also decreased 0.8% among older men but did not reach significance (95% CI: -2.6%, 4.2%). DID analysis did not show difference in changes between men aged 55-69 in reference to men >70 from both 2015 to 2019 (DID=-1.9%, 95%CI, -6.7%, 2.9%) and 2019 to 2021 (DID =-2.3%, 95%CI, -6.5%, 1.9%). CONCLUSION(S): We saw an increase in PSA screening after 2018 USPSTF recommendations among its target population e men aged 55-69 and also among older men >70. In contrast, the period from 2019 to 2021 saw a significant decrease in PSA screening in those aged 55-69. The lack of significant DID between groups as well as the downward trend of PSA screening in men >70 together suggest an overall trend of decrease in PSA screening post-Pandemic.
ABSTRACT
INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic placed a significant burden on the US healthcare system. Moreover, many healthcare systems triaged cases based on the severity of disease. Therefore, we assessed the impact of the COVID-19 pandemic on prostate cancer management according to the International Society of Urological Pathology (ISUP) grade groups. METHOD(S): We retrospectively analyzed the National Cancer Database (NCDB) for patients with prostate cancer between 2018- 2020. We divided our cohort into "Pre-Pandemic" (2018/2019) and "Pandemic" (2020) periods. Men were classified according to their ISUP grade group at diagnosis. Hospital characteristics and patient-level clinical and sociodemographic variables were extracted. Our primary outcome was the utilization of definitive treatment (surgery or radiation) versus expectant management (active surveillance, watchful waiting, or no treatment). We performed multivariable logistic regressions to predict the type of management for each ISUP grade group across the two periods adjusting for clinical and socioeconomic covariates. RESULT(S): A total of 398,719 men with a diagnosis of prostate cancer were reported during the "Pre-Pandemic" (70.6%) and "Pandemic" (29.4%) periods. Overall, 24.5% had an ISUP 1, 30.6% an ISUP 2, 18.2% an ISUP 3, 13% ISUP 4, and 13.8% ISUP 5 disease (Table 1). Treatment was less likely during the "Pandemic" compared to the "Pre-Pandemic" period for ISUP grade group 1 (aOR 0.80;95% CI 0.77 - 0.83;p-value <0.001), for ISUP grade group 2 (aOR 0.85;95% CI 0.81 - 0.89;p-value <0.001) and for ISUP grade group 3 (aOR 0.87;95% CI 0.80 - 0.96;p-value <0.003). However, no differences in treatment trends were found for ISUP grade groups 4 and 5 across the two time periods. CONCLUSION(S): During the COVID-19 pandemic, patients with prostate cancers ISUP grade groups 1, 2, and 3 were more likely to receive expectant management than definitive treatment;however, this was not true for patients with more aggressive diseases. This finding suggests a high capacity of facilities to appropriately risk stratify and prioritize higher-risk cases during a public health emergency. A limitation of our study is the inability to assess the treatment trends of men diagnosed in the last 2020 quarter due to the lack of follow-up.
ABSTRACT
INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic likely affected the healthcare system's ability to deliver prostate cancer care services. Herein, we sought to evaluate prostate cancer's stage and grade migration resulting from the COVID-19 pandemic. METHOD(S): We retrospectively analyzed the National Cancer Database (NCDB) for men with prostate cancer between 2018-2020. We divided our cohort into the "Pre-Pandemic" (2018/2019) and "Pandemic" (2020) periods. Stage and grade of prostate cancer were stratified according to the severity of disease: PSA value (<=20 vs. >20), clinical T stage (cT1-T2 vs. cT3-T4), clinical M stage (cM0 vs. cM1), International Society of Uropathology (ISUP) grade group (ISUP 1-2-3 vs. ISUP 4-5), and D'Amico risk classification (low risk vs. intermediate & high risk). Pearson's chi-square test was used to assess differences in the distribution of stage and grade across the two periods. We performed multivariable logistic regressions to estimate the effect of the "Pandemic" period on stage and grade distribution adjusting for clinical and socioeconomic covariates. RESULT(S): A total of 398,719 men were diagnosed with prostate cancer during the "Pre-pandemic" (70.6%) and "Pandemic" (29.4%) periods (Table 1). On univariable comparisons, an increase in stage/ grade across the two periods was demonstrated (all p<0.001). After adjusting for covariates, compared to the "Pre-pandemic", the "Pandemic" period was associated with increased odds of PSA >20 levels (aOR 1.06;95% CI 1.03 - 1.08;p-value <0.001), cT3-4 stages (aOR 1.12;95% CI 1.08 - 1.16;p<0.001), cM1 stage (aOR 1.15;95% CI 1.12 - 1.18;p<0.001), ISUP grade group 4 or 5 (aOR 1.03;95% CI 1.01 - 1.05;p=0.003) and D'Amico Intermediate & High risk groups (aOR 1.15;95% CI 1.13 - 1.18;p<0.001). CONCLUSION(S): The COVID-19 pandemic was associated with significant changes in the distribution of both stage and grade of prostate cancer. Possible explanations for this migration include a better selection of patients for prostate biopsy during the pandemic or changes in prostate cancer screening patterns.
