1688P Outcome of older cancer patients infected with COVID-19 at Gustave Roussy Cancer Center

Abstract

Background: The SARS-CoV-2 outbreak significantly affected Gustave Roussy cancer center Here, we report the Gustave Roussy experience on older patients (OP) with cancer during the SARS-CoV-2 outbreak Methods: Cancer pts with suspected SARS-CoV-2 infection were admitted at Gustave Roussy starting March, 12th Screening indications have been adapted over time All the COVID-19 pts positively tested and managed at Gustave Roussy between March 14th and April 15th have been included in a redcap database Pts and underlying oncological and COVID-19 diseases characteristics have been collected Cancer and COVID-19 managements, and outcomes have been assessed The primary endpoint of this analysis was the clinical deterioration, defined as the need for O2 supplementation of 6l/min or more, or death of any cause Results: Among the first 137 cancer pts diagnosed with SARS-CoV-2, 36 patients were aged 70 years old or over (26%) Most of them were female (61%) with a median age of 75 5 years old Most frequent underlying cancers were solid tumors (92%) including GI (19%), lung (17%), GYN (14%) and head and neck (14%) Most OP (36%) were ECOG Performans status 2 versus 24% in younger patients (YP) The diagnosis of SARS-CoV-2 infection was made by RT-PCR or thoracic CT scan alone in 97% and 3% of the cases, respectively in OP and in 92% and 8% in YP Most OP experienced symptoms prior to testing (92%) compared to YP (80%) Symptoms differed according to age with more cough with sputum production in OP (14% versus 5%), dyspnea (39% versus 31%), diarrhea (17% versus 9%), shivers (8% versus 0%), sore throat (8% versus 4%) and no anosmia nor agueusia The majority of OP was hospitalized (81%) compared to 72% of YP and treated with HCQ/AZI (15;52%) compared to 25 (35%) YP with inclusion in the ONCOVID trial (EudraCT: 2020-01250-21) They did not receive any IL-6 inhibitor Only one OP was admitted in the ICU (3%) Clinical deterioration occurred in 10 OP (29%) There was no impact of age on clinical worsening (HR=1 157;95%CI 0 55-2 42;p=0 7) However age was associated with worse overall survival (OS) (HR=2 45 95%CI 1 02-5 92;p=0 0463) Results will be updated at the meeting Conclusions: OP with cancer had a different disease presentation, same rate of clinical worsening but worse OS in SARS-CoV-2 infection Legal entity responsible for the study: The authors Funding: Has not received any funding Disclosure: All authors have declared no conflicts of interest
