Initial reporting from the prospective National Cancer Institute (NCI) COVID-19 in Cancer Patients Study (NCCAPS)

ABSTRACT

Background: Patients (pts) with cancer are at increased risk of SARS-CoV-2 infection and severe COVID-19 disease. Longitudinal followup is needed to characterize the severity, sequelae and outcomes in pts with cancer who develop COVID-19. Methods: NCCAPS is a prospective, longitudinal study (NCT04387656) aiming to accrue 2,000 pts with cancer undergoing active treatment or prior stem cell transplant for hematologic or solid tumor malignancy. Adult patients are eligible to enroll within 14 days of their first positive SARS-CoV-2 test;pediatric patients may also enroll retrospectively. Clinical data, patient-reported outcomes, blood specimens, and imaging are collected for up to 2 years. This abstract provides initial baseline and 2-month follow-up data. Results: As of Jan 22, 2021, 585 pts (552 adults and 33 pediatric pts) had complete baseline data and of these pts, 215 adults had 2 months of complete follow-up data. 23.4% of adults and 42.4% of pediatric pts were of nonWhite race and/or Hispanic/Latinx ethnicity. The most common cancer diagnoses were breast (19.6%), lung (9.9%) and multiple myeloma (8.9%) in adults and acute leukemia (AML/ALL;63.6%) in children. The most recent treatment was chemotherapy in 38.2%, immunotherapy in 9.6%, and radiation in 5.4%. Median time from positive SARS-CoV-2 test to study enrollment was 10.5 days in adults and 18 days in pediatric pts. Preliminary analysis of plasma cytokines will be presented. At enrollment, 84.6% of adults had COVID-19 symptoms. 55.9% reported symptoms 2 weeks after their positive SARSCoV-2 test;this fell to 39.0% at 1 month and 28.8% at 2 months (see Table). Of the 215 adults with complete data at 2 months, sequelae included pulmonary (n=22, 10%), cardiovascular (n=12, 6%) thromboembolic (n=9, 4%), bleeding (n=9, 4%) and gastrointestinal (n=11, 5%). 144 (67%) reported at least one cancer treatment disruption in the first 2 months, most commonly delayed therapy (n=98;46%).Of the 348 adults with baseline data and SARS-CoV-2 test date prior to Nov 23, 2020, 6.3% had died (median time from SARS-CoV-2 test to death 27 days), and 22.1% reported at least one hospitalization for COVID-19. No deaths were reported in the pediatric population. Conclusion: Cancer pts with COVID-19 report ongoing symptoms after acute infection and a substantial number develop sequelae. Cancer treatment disruptions are common in the initial months following SARS-CoV-2 infection. Longer follow-up will inform whether these treatment disruptions are associated with adverse outcomes.
