Impact of COVID-19 on pancreatic cancer outcomes in Florida

ABSTRACT

Introduction: Pancreatic cancer (PC) is currently the third-leading cause of cancer deaths in the United States. African Americans with PC have an increased incidence and worse survival outcome when compared to other racial groups. During the COVID-19 pandemic, there is evidence that hospital resources were allocated to treating immediate life-threatening conditions. Some of the daily highest case numbers were reported in the state of Florida with several peaks throughout 2020 and 2021. Additionally, the state of Florida has the second-highest rate of new cases of PC within the United States with an incidence of 4860/100,000. Our specific aim is to define the impact of COVID-19 between race, age, income, and gender on the survival time of newly diagnosed patients with pancreatic cancer in Florida. Material(s) and Method(s) Patients with pancreatic adenocarcinoma diagnosed from January 1st, 2017 to October 31st, 2020 were identified through the statewide clinical research and network database called OneFlorida Clinical Consortium by using the ICD10 diagnosis code for pancreatic cancer. Patients were then placed into 3 cohorts based on date of pancreatic cancer diagnosis pre-pandemic (01/01/2017- 09/30/2019), transition (10/01/2019-02/28/2020), and pandemic (03/1/2020-10/31/2020). Patients with a diagnosis of neuroendocrine carcinoma were excluded. Patients were followed for at least one year unless a death occurred. Summary statistics were reported for demographic variables (age, sex, income, gender). Kaplan-Meier analysis with log-rank test was performed to compare the difference in overall survival time among groups. Result(s) This retrospective study had a total of 934 unique patients available for analysis. Of the 934 patients, 81.3% were in the pre-pandemic cohort (n= 759), 8.2% transition cohort (n=77), and 10.5% pandemic cohort (n=98). There was a decrease in the rate of diagnosis from the pre-pandemic (23 per month) to pandemic cohort (12.2 per month). The demographic distribution of the sample was 23.4% Black, 68.7% White and 7.9% Other. The median age was 67 years (27-89). There were 49.8% women and 50.2% men. The median income was $52,915 ($23,704-$124,821). The differences in overall survival time were not significant for age and gender across the 3 cohorts. Income <;$53,000 had significantly lower survival time across the 3 cohorts. African Americans had significantly lower survival time for pre-pandemic and transition cohort (p<;.005), but Caucasians had the lowest survival time for the pandemic cohort (p <;.005). When stratified for stage, the mean survival (in months) for White vs. Black populations was 37.8 vs. 26.1 for stage I, 37.6 vs. 27.3 for stage II, 28.5 vs.18.77 for stage III, and 20.7 vs. 21.7 for stage IV. Discussion(s) This study demonstrated a decrease in diagnosis & survival rate during the COVID-19 pandemic in Florida. Dissemination of resources should target these disparities in income and race.
