1693P - Accurate triage may be efficacious in selecting patients who could safely continue anticancer therapy during SARS-CoV-2 pandemic

Background

During the SARS-COV-2 pandemic, cancer patients (pts) who are infected may develop severe disease if their systemic treatment is not temporarily stopped. Nasopharyngeal swab was not extensively available to screen cancer pts for SARS-COV-2 infection in northern Italy, the most area in the country most affected by the pandemic. From the beginning of the outbreak onwards, all pts admitted to the Medical Oncology Unit at Spedali Civili Hospital, Brescia, underwent a triage investigating the presence of symptoms and signs suggestive of SARS-COV-2 infection. Triage results were used to decide which pts should continue antineoplastic treatments.

Methods

All consecutive cancer pts being admitted for systemic treatment from February 24^th to April 21^st 2020 were considered. Triage, performed by a trained nurse, consisted of questions regarding the presence of fever, cough, dyspnea, anosmia, dysgeusia, headache, nasal congestion, conjunctival congestion, sore throat, diarrhoea, nausea and vomiting, measurement of body temperature and pulse oximetry. All enrolled pts were followed-up for overt SARS-COV-2 development until May 18^th.

Results

Overall, 1180 pts were included, 54% female and median age 65 years. Most represented primary malignancies were breast (32%), gastroenteric (18%) and lung (16.5%). Thirty-one (2.5%) presented with clinically evident SARS-COV-2 disease and infection was proven by positive nasopharyngeal swab and/or radiological imaging. The triage identified 69 (6%) “grey zone” pts, with suspicious symptoms (i.e. fever 41%, cough 30%, dyspnea 19%). The nasopharyngeal swab was negative in 48% of them and was not performed in the remaining 52% of pts, as well as in all pts who were triage negative. Both SARS-COV-2 positive and “grey zone” pts did not receive treatment and were addressed to hospitalisation or home quarantine. All the 1080 pts (91.5%) who resulted negative at triage continued their antineoplastic therapy as scheduled, none of them presenting symptoms of SARS-COV-2 infection during the follow-up.

Conclusions

Accurate triage allowed safe continuation of anticancer treatment in 91.5% of pts during the SARS-COV-2 outbreak.
