AbstractBackground Since the beginning of the COVID-19 pandemic, multiple changes to the provision of cancer care has been introduced to maximize patient safety and protect staff. We aimed to identify factors influencing clinicians’ decision on treatment modification during the initial phase of the pandemic, and to assess its impact on outcomes in patients with colorectal cancer. Patients and Methods Electronic records of patients seen in a large United Kingdom tertiary cancer center was reviewed. The frequency and type of changes to systemic anticancer therapy , as well as the factors predicting clinicians’ decision were assessed. Results A total of 418 patients; mean age 63 ± 12 years and 57% male were included. More than half of the patients had modification to their treatment; with treatment delay (21%) or cancellation (10%), being the most common. Majority of patients on neoadjuvant treatment (97%) proceeded with treatment, with some form of treatment modification in 20%. Half of patients on adjuvant treatment had their treatment plan modified. Overall, a change in treatment was more likely in older patients (OR 1.028 [95% CI 1.010-1.047]; P = .002), and in patients who had already received higher number of cycles of systemic anticancer therapy (OR 1.040 [95% CI 1.016-1.065]; P = .001). A change in treatment was less likely further out of the first national lockdown (OR 0.837 [95% CI 0.758-0.925]; P < .001). Patients on third-line treatment were most likely to have alterations to their treatment plan (69%, n=33/48). Conclusion During the first wave of COVID-19 in the United Kingdom, clinicians adapted clinical practice in accordance to local and national guidance, especially amongst older patients and those on third-line treatment. Further real-world data are needed to document the important impact of changes to treatment on outcomes in patients with cancer.
