Background The indirect impact of the COVID-19 pandemic on cancer outcomes is of increasing concern. However, the extent to which key treatment modalities have been affected is unclear. We aimed to assess the impact of the pandemic on radiotherapy activity in England. MethodsIn this population-based study, data relating to all radiotherapy delivered for cancer in the English NHS, between Feb 4, 2019, and June 28, 2020, were extracted from the National Radiotherapy Dataset. Changes in mean weekly radiotherapy courses, attendances (reflecting fractions), and fractionation patterns following the start of the UK lockdown were compared with corresponding months in 2019 overall, for specific diagnoses, and across age groups. The significance of changes in radiotherapy activity during lockdown was examined using interrupted time-series (ITS) analysis. FindingsIn 2020, mean weekly radiotherapy courses fell by 19•9% in April, 6•2% in May, and 11•6% in June compared with corresponding months in 2019. A relatively greater fall was observed for attendances (29•1% in April, 31•4% in May, and 31•5% in June). These changes were significant on ITS analysis (p<0•0001). A greater reduction in treatment courses between 2019 and 2020 was seen for patients aged 70 years or older compared with those aged younger than 70 years (34•4% vs 7•3% in April). By diagnosis, the largest reduction from 2019 to 2020 in treatment courses was for prostate cancer (77•0% in April) and non-melanoma skin cancer (72•4% in April). Conversely, radiotherapy courses in April, 2020, compared with April, 2019, increased by 41•2% in oesophageal cancer, 64•2% in bladder cancer, and 36•3% in rectal cancer. Increased use of ultra-hypofractionated (26 Gy in five fractions) breast radiotherapy as a percentage of all courses (0•2% in April, 2019, to 60•6% in April, 2020; ITS p<0•0001) contributed to the substantial reduction in attendances.Interpretation Radiotherapy activity fell significantly, but use of hypofractionated regimens rapidly increased in the English NHS during the first peak of the COVID-19 pandemic. An increase in treatments for some cancers suggests that radiotherapy compensated for reduced surgical activity. These data will assist health-care providers in understanding the indirect consequences of the pandemic and the role of radiotherapy services in minimising these consequences.

AimsRadiotherapy is an important treatment modality in the multidisciplinary management of rectal cancer. It is delivered both in the neoadjuvant setting and postoperatively, but, although it reduces local recurrence, it does not influence overall survival and increases the risk of long-term complications. This has led to a variety of international practice patterns. These variations can have a significant effect on commissioning, but also future clinical research. This study explores its use within the large English National Health Service (NHS).Materials and methodsInformation on all individuals diagnosed with a surgically treated rectal cancer between April 2009 and December 2010 were extracted from the Radiotherapy Dataset linked to the National Cancer Data Repository. Individuals were grouped into those receiving no radiotherapy, short-course radiotherapy with immediate surgery (SCRT-I), short-course radiotherapy with delayed surgery (SCRT-D), long-course chemoradiotherapy (LCCRT), other radiotherapy (ORT) and postoperative radiotherapy (PORT). Patterns of use were then investigated.ResultsThe study consisted of 9201 individuals; 4585 (49.3%) received some form of radiotherapy. SCRT-I was used in 12.1%, SCRT-D in 1.2%, LCCRT in 29.5%, ORT in 4.7% and PORT in 2.3%. Radiotherapy was used more commonly in men and in those receiving an abdominoperineal excision and less commonly in the elderly and those with comorbidity. Significant and substantial variations were also seen in its use across all the multidisciplinary teams managing this disease.ConclusionDespite the same evidence base, wide variation exists in both the use of and type of radiotherapy delivered in the management of rectal cancer across the English NHS. Prospective population-based collection of local recurrence and patient-reported early and late toxicity information is required to further improve patient selection for preoperative radiotherapy.

Introduction: Between 1987 and 1994 three randomised phase III trials demonstrated that

Immune checkpoint inhibitors (CPIs) have radically changed outcomes for patients diagnosed with metastatic melanoma globally in the last 10 years, based on evidence of overall survival (OS) benefits generated from international randomised controlled trials (RCTs). Since RCTs do not always reflect real-world prescribing, we interrogated established national databases to track prescribing of CPIs approved for first line treatment of metastatic melanoma patients in England since 2014 and determined patient outcomes associated with OS, as well as treatment-related toxicity. Between April 2014 and March 2018, 5465 melanoma patients were diagnosed and treated with systemic anticancer therapy (SACT), 2322 of which received first-line CPIs. There was good 3-year OS concordance with RCT outcomes for ipilimumab (32%), ipinivo (56%) and nivolumab (51%), but OS was lower than expected for pembrolizumab (40%). Comparing patients prescribed ipinivo with those prescribed pembrolizumab, ipinivo-treated patients were younger (88% vs 49% patients <70 years, P < .001) and fitter (60% vs 38% patients with Eastern Cooperative Oncology Group [ECOG] performance status 0, P < .0001). Emergency hospital admission rates from the earliest and last treatment dates were higher for patients prescribed ipinivo (37% and 55%) compared to those prescribed pembrolizumab (17% and 29%). The 30-day mortality rates favoured ipinivo patients (3.8% ipinivo, 9.1% pembrolizumab, P < .0001) and likely reflected marked differences in median treatment durations: 63 (range 7-440) days for ipinivo and 192 (range 5-943) days for pembrolizumab. The dominant treatment-related condition linked to hospital admission was colitis, recorded for 25% of patients prescribed ipinivo compared to 4% of patients prescribed pembrolizumab. Our population data has demonstrated that RCT outcomes can be achieved in routine care settings with careful patient selection.

55 Background: Population-based research provides real world information about prescribing trends, as well as benefits and harms associated with new interventions first evaluated in randomized clinical trials (RCTs). The national health service in England has comprehensive databases which we used to track prescribing of checkpoint inhibitors (CPIs) approved for 1st line use in metastatic melanoma and determine patient outcomes associated with survival and treatment toxicity. Methods: National Cancer Registration and Analysis Services (NCRAS) datasets were used to identify metastatic melanoma patients (pts) prescribed 1st line CPIs and calculate survival outcomes. The HES (Hospital Episode Statistics) database was used to identify emergency attendances and emergency hospital admissions. Results: 5465 melanoma pts were registered between April ‘14 and March ‘18. 2322 pts received 1st line CPIs: 1174 pembrolizumab (pem), 724 ipilimumab (ipi), 52 nivolumab (nivo), 372 ipinivo. Prescribing reflected national access, with ipi starting in July ‘14 and dropping rapidly on approval of pem in Nov ’15. Ipinivo prescriptions increased annually since July ’16. There was good 3yr OS concordance with RCT outcomes for ipinivo (56%), nivo (51%), pembro (40%) and ipi (32%). Pts treated with ipinivo were significantly younger (88% vs 49% <70 years, P<0.001) and fitter (60% vs 38% ECOG PS 0, P<0.0001) than pts treated with antiPD1. 30-day mortality from last SACT was 3.8% for ipinivo, 9.1% for antiPD1 and 9.4% for ipi. 30-day rates of emergency hospital admissions/A&E emergency attendances from the earliest SACT and last SACT treatment dates were significantly higher for ipinivo (37%/16% and 55%/19%) compared with antiPD1 (17%/8% and 29%/14%) and ipi (24%/9% and 40%/15%), P<0.01. 25% of ipinivo-, 4% of antiPD1- and 15% of ipi-treated pts had a hospital admission for colitis. Conclusions: This largest real world dataset demonstrated rapid uptake of CPIs and survival outcomes similar to RCTs. Use of emergency services varied by regimen, with colitis dominating hospitalization after ipi+/-nivo. Pt selection appeared to differ for different regimens, the consequences of which warrant further research.
