ABSTRACT
Background: The SARS-CoV-2 pandemic has had an unprecedented impact on healthcare systems, and cancer patients were amongst the most vulnerable. CONTACT is a national multidisciplinary study assessing the impact of the SARS-CoV-2 pandemic upon diagnostic and treatment pathways among patients with pancreatic ductal adenocarcinoma (PDAC). Method(s): A novel, mixed prospective and retrospective design, with retrospective case identification of both cohorts, and trainee-performed data collection. The treatment of consecutive patients with newly diagnosed PDAC from a pre-COVID cohort (07/01/ 2019-03/03/2019) were compared to a cohort diagnosed during the first wave of SARS-CoV-2 in the UK ('COVID' cohort, 16/03/2020-10/05/ 2020), with 12-month follow-up. Result(s): Among 984 patients (pre-COVID: N=483, COVID: N=501), across 96 hospitals, the COVID cohort were less likely to receive staging investigations other than CT scan (148/501, 29.5% vs 180/486, 37.2%;p=0.01). Among patients treated with curative intent, there was a reduction in the proportion of patients recommended surgery (42/77, 54.5% vs 72/94, 76.6%, p=0.001) and increase in the proportion recommended neoadjuvant therapy (35/77, 45.5% vs 22/94, 23.4%, p=0.002). Among patients within a non-curative pathway, fewer patients were recommended (201/424, 47.4% vs 223/389, 57.3%, p=0.004) or received palliative therapy (87/424, 20.5% vs 103/389, 26.5%, p=0.045). Ultimately, fewer patients in the COVID cohort underwent resection surgery (29/501, 6.4% vs 45/483, 9.3%, OR 0.64, 95%CI: 0.37- 0.97, p=0.036), whilst more patients received no treatment whatsoever (347/ 501, 69.3% vs 286/483, 59.2% p=0.009). There was no difference in median survival between the COVID and pre-COVID cohorts, (105 days, IQR: 86-124 vs 130 days, IQR: 108-157, p=0.093). Conclusion(s): The CONTACT study confirms alarming reduction in the staging and treatment provided to patients with PDAC diagnosed during the SARS-CoV-2 pandemic. Restoration of cancer services to pre-pandemic standards must be urgently addressed.
