1533 Background: At the outset of the COVID-19 pandemic, concerns for the safety of patients receiving anti-cancer treatment coupled with pressures on healthcare services prompted review of standard clinical care pathways in the UK. Revised consensus treatment guidelines were generated. Individual patient-level data regarding actual treatment modifications implemented in clinical practice are lacking. Methods: All anti-cancer treatment plans of patients with breast, lung, renal, hepatopancreatobiliary, CNS cancers and melanoma attending a single academic cancer centre in the UK between 16 March and 31 May 2020 were reviewed and any modifications to standard practice were documented. The effect of patient (age, ECOG performance status [PS], sex) and cancer (site, stage, treatment intent) characteristics on likelihood of treatment modifications were analysed using univariable and multivariable models. Results: Treatment plans for 925 patients were reviewed: median patient age was 63 (range 19-97); 66% were female; 73% were PS 0-1; 45% were on a curative pathway. Overall, 47% of all patients had one or more modifications made to their treatment plans: 53% of surgeries (primarily being delayed); 41% of radiotherapy (primarily reduced fractions delivered); 39% of systemic therapy prescriptions. 96-100% of all systemic therapy modifications resulted in treatment de-escalation, excluding endocrine therapy used as a bridge to defer primary breast cancer surgery. Biological therapy was predominantly interrupted (49%), immunotherapy was mostly omitted entirely (36%), and chemotherapy varied between interruptions (39%) or omissions (31%). Relative to the likelihood of modification to chemotherapy, surgery was significantly more likely to be modified (OR 1.69 95%CI 1.20-2.38). Chemotherapy, radiotherapy, biological therapy and immunotherapy were all modified to a similar degree. Multivariate analysis identified PS ≥2 (OR 1.79, 95% CI 1.18–2.75), but not patient age, as a predictor of treatment modification. Some tumour types were less likely to undergo any modification: stage 1-3 lung (OR 0.13, 95%CI 0.04-0.37), stage 4 lung (OR 0.26 95%CI 0.24–0.60) and stage 4 renal cancer (OR 0.22 95%CI 0.09-0.52). Conclusions: This single centre analysis demonstrated almost half of cancer patients had their treatment modified, the overwhelming majority resulting in treatment de-escalation. The impact of the treatment modifications on overall cancer patient outcomes remains to be determined.
