The impact of the COVID-19 pandemic on patients with pancreatic cancer.

BACKGROUND

It remains unclear today whether the poor prognosis of pancreatic ductal adenocarcinoma (PDAC) was further worsened by the COVID-19 pandemic and whether this may affect providers and patients, today. Hence, this study aimed to investigate the effect of COVID-19 on care delivery and outcomes of patients with PDAC in the United States.

METHODS

The National Cancer Database was queried for PDAC, between 2017 and 2020. Changes in the number of diagnoses and treatment patterns were compared annually for the entire cohort. Changes in surgical outcomes and median time from diagnosis to treatment were compared and analyzed. Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were performed.

RESULTS

Of 127,613 patients with PDAC, PDAC diagnoses from 2017 (30,573) to 2019 (33,465) increased but decreased in 2020 (31,218). The number of patients receiving surgery or radiotherapy was stable between 2017 to 2019 (21.75% ± 0.05% and 13.9% ± 0.3%, respectively) but decreased in 2020 (20.7% and 12.4% respectively). Although patients received chemotherapy with increasing frequently from 2016 (60.7%) to 2019 (63.5%), this trend stopped in 2020 (63%). Of 27,490 patients undergoing surgery, the mean time from diagnosis to surgery increased from 2017 (34 days) to 2019 (56 days), with an increase in delay in 2020 (81 days). Moreover, patients who were tested for COVID-19, had a longer median time from diagnosis to surgery even if tested negative (COVID+, 140 days; COVID-, 112 days; P < .001).

CONCLUSION

Although the oncologic quality of PDAC surgery remained the same during the pandemic, not only did the pandemic lead to an underdiagnosis of PDAC and care delays, but even the suspicion of COVID-19 in patients with a negative test adversely affected their care.
