Background Using an updated dataset with more patients and extended follow-up, we further established cancer patient characteristics associated with COVID-19 death. Methods Data on all cancer patients with a positive reverse transcription-polymerase chain reaction swab for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) at Guy’s Cancer Centre and King’s College Hospital between 29 February and 31 July 2020 was used. Cox proportional hazards regression was performed to identify which factors were associated with COVID-19 mortality. Results Three hundred and six SARS-CoV-2-positive cancer patients were included. Seventy-one had mild/moderate and 29% had severe COVID-19. Seventy-two patients died of COVID-19 (24%), of whom 35 died <7 days. Male sex [hazard ratio (HR): 1.97 (95% confidence interval (CI): 1.15–3.38)], Asian ethnicity [3.42 (1. 59–7.35)], haematological cancer [2.03 (1.16–3.56)] and a cancer diagnosis for >2–5 years [2.81 (1.41–5.59)] or ≥5 years were associated with an increased mortality. Age >60 years and raised C-reactive protein (CRP) were also associated with COVID-19 death. Haematological cancer, a longer-established cancer diagnosis, dyspnoea at diagnosis and raised CRP were indicative of early COVID-19-related death in cancer patients (<7 days from diagnosis). Conclusions Findings further substantiate evidence for increased risk of COVID-19 mortality for male and Asian cancer patients, and those with haematological malignancies or a cancer diagnosis >2 years. These factors should be accounted for when making clinical decisions for cancer patients.
Background: The Coronavirus disease 2019 (COVID-19) pandemic continues to have a significant impact on the treatment of cancer patients. Understanding the clinical course, potential risk factors for severe infection and excess mortality, is essential to improve patient outcomes. We previously presented preliminary results from 156 SARS-CoV-2 positive cancer patients from Guy’s Cancer Center, which suggested that increased COVID-19 mortality was associated with a diagnosis of cancer for over 2 years, Asian ethnicity and being on palliative treatment. Herein, we present an updated analysis using data from Guy’s Cancer Centre and a partner Hospital Trust (King’s College Hospital), with an increased number of patients and an extended follow up. Methods: We performed an analysis of all cancer patients who had a positive RT-PCR nasal/throat swab for SARS-CoV-2 infection at our Centers between 29th February and 31st July 2020. Associations between patients’ demographics, clinical characteristics, and laboratory investigations with COVID-19 severity and mortality, were assessed using Logistic regression and Cox proportional hazards models. Results: 306 SARS-CoV-2 positive cancer patients were included in the analysis with a median follow up of 134 days (IQR 32-156). 184 (60%) were male and 217 (71%) were aged over 60 (mean age: 66). The most common malignancies were haematological (38%) and urological-gynaecological (20%). 218 (71%) had mild/moderate COVID-19 and 88 (29%) had severe disease. The overall COVID-related mortality rate was 24%; 19% in solid and 32% in haematological cancers. Male sex [OR: 1.84 (95%CI:1.08-3.13)], Asian ethnicity [3.86 (1.20-12.36)], haematological cancer type [2.16 (1.18-3.95)], being diagnosed with cancer for 2-5 years [3.74 (1.80-7.78)] or ≥5 years [3.06 (1.50-6.26)] and a ferritin > 1964 mcg/l [54.92 (5.90-511.33)] were all associated with a risk of developing severe COVID-19 disease. Similarly, male sex [HR:1.97 (95%CI:1.15-3.38)], Asian ethnicity [3.42 (1. 59-7.35)], haematological cancer type [2.03 (1.16-3.56)] as well as a cancer diagnosis for >2-5 years [2.81 (1.41-5.59)] or ≥5 years [2.13 (1.06-4.27)] and a ferritin > 1964 mcg/l [16.11 (3.81-68.17)] were associated with an increased risk of death from COVID-19. Age >60 [2.14 (1.15-3.98)] and a raised CRP [4.10 (1.66-10.10)] were also associated with COVID-19 death. An inverse relationship was observed between a raised albumin and COVID-19 related death [0.12 (0.03-0.51)]. Performance status and treatment paradigm were not associated with COVID-19 severity or mortality. Conclusions: This study further substantiates the evidence for an increased risk of severe COVID-19 infection and mortality for male and Asian patients with cancer, and those with haematological malignancies or with a diagnosis of cancer for over 2 years. These risk factors should be taken into account when making clinical decisions for cancer patients during the pandemic.

Introduction: Cancer patients have been considered a high-risk population in the COVID-19 pandemic. We previously investigated risk of COVID-19 death in COVID-19 positive cancer patients during a median follow-up of 134 days, and identified the following risk factors: male sex, age >60 years, Asian ethnicity, hematological cancer type, cancer diagnosis for >2.5 years, patients presenting with fever or dyspnea, and high levels of ferritin and C-reactive protein (CRP). Here, we further investigate which factors are associated with a COVID-19 related death within 7 days of diagnosis. Methods: Using data from Guy’s Cancer Centre and one of its partner trusts (King’s College Hospital), we included 306 cancer patients with a confirmed COVID-19 diagnosis (February 29th-July 31st 2020). 72 patients had a COVID-19 related death (24%) of whom 35 died within 7 days (50%). Cox proportional hazards regression was used to identify which factors were associated with a COVID-19 related death <7 days of diagnosis. Results: Of the 72 cancer patients who had a COVID-19 related death, the mean age was 72 years (Standard Deviation (SD) 14). A total of 53 (74%) patients were men. 37 (52%) had a hematological cancer type, 47 (65%) had stage IV cancer, and 42 (58%) had been diagnosed with cancer more than 24 months before COVID-19 related death. In the group of patients who died within 7 days of diagnosis (n= 35), mean age was 73 years (SD 13.96), 24 (68%) were men, 20 (57%) had a hematological cancer type, 26 (74%) had stage IV cancer, and 24 (68%) had been diagnosed with cancer >24 months before COVID-19 diagnosis. Factors associated with COVID-19 related death <7 days of diagnosis were: hematological cancer (Hazard Ratio (HR): 2.74 (95% Confidence Interval (CI): 1.21-6.22)), 2-5 yrs since cancer diagnosis (HR: 4.81 (95%CI: 1.47-15.69)), and >5 yrs since cancer diagnosis (HR: 4.41 (95%CI: 1.38-14.06)). Additionally, patients who presented with dyspnea had increased risk of COVID-19 related death <7 days compared to asymptomatic patients (HR: 5.25 (95%CI 2.14-12.89)). CRP levels in the third tercile (146-528 mg/L) as compared to the first were also associated with increased risk of an early death due to COVID-19. Conclusion: From all the factors identified in our previous COVID-19 related death analysis, only hematological cancer type, a longer-established cancer diagnosis (2-5 years and more than 5 years), dyspnea at time of diagnosis and high levels of CRP were indicative of an early COVID-19 related death (within 7 days of diagnosis) in cancer patients.

Background It is widely accepted that advancing age is associated with worse COVID-19 outcomes. However, there is insufficient data analyzing the impact of COVID-19 in the older cancer population. The aim of the study is to establish if age has an influence on severity and mortality of COVID-19 in cancer patients. Methods We reviewed 306 oncology patients with PCR-confirmed COVID-19 from Guy’s Cancer Centre and its partner Trust King’s College Hospital, between 29 February – 31 July 2020. Demographic and tumor characteristics in relation to COVID-19 severity and death were assessed with logistic and Cox proportional hazards regression models, stratified by age (≤65 and >65 years). Severity of COVID-19 was classified by World Health Organization (WHO) grading. Results A total of 135 patients were aged ≤65 years (44%) and 171 aged >65 (56%). Severe COVID-19 presentation was seen in 27% of those aged ≤65 and 30% of those aged >65. The COVID-19 mortality rate was 19% in those aged ≤65 and 27% in those aged >65. In the older cohort, there was an increased incidence of severe disease in Caucasian ethnicity compared to the younger cohort (55% vs 43%) and compared to severe disease in Black and Asian ethnicities. There were increased co-morbidities in the older cohort including hypertension (54% vs 32%), diabetes (30% vs 12%) with increased rate of poly-pharmacy (62% vs 40%) compared to the younger cohort. In terms of cancer characteristics in the older cohort, there was a higher rate of patients with cancer for more than 2 years (53% vs 32%) and performance status of 3 (22% vs 6%). In terms of severity, Asian ethnicity [OR: 3.1 (95% CI: 0.88-10.96) p=0.64] had greater association with increasing COVID-19 severity in those aged >65. Interestingly, there were no positive associations between number of co-morbidities, treatment paradigm or performance status with severity of disease in the older group. The risk of mortality was greater in the elderly cohort with hematological cancer types [HR: 2.69 (1.31-5.53) p=0.85] and having cancer for more than 2 years [2.20 (1.09-4.42) p=0.28] compared to the younger cohort. Conclusions In our study we demonstrate that severity and mortality of COVID-19 did not significantly differ between the two age cohorts except in regards to Asian ethnicity, hematological malignancies and having cancer for more than 2 years. As expected, the older population had more co-morbidities and polypharmacy. Despite this, the incidence of severe COVID-19 was similar regardless of age. Further analyses for other geriatric presentations are ongoing to understand their interaction with COVID-19 in the cancer population.
