PURPOSE

Unlike most childhood cancers, therapy for ALL includes a prolonged maintenance phase during which children typically resume regular activities. Physicians need data regarding the persistent impact of COVID-19 in this population to help guide families after the pandemic.

METHODS

The Pediatric Oncology COVID-19 Case Report (POCC) collects deidentified data (sociodemographics, clinical data [cancer, COVID-19 course]) on children, adolescents, and young adults with cancer and COVID-19 from 104 US pediatric oncology institutions. The analysis presented here compares children (≤21 years) with ALL in maintenance (ALL-MTN) with all other children with cancer and COVID-19. Multivariable analyses adjust for age, race/ethnicity, insurance, absolute neutrophil count at the time of infection, vaccination, and comorbidities.

RESULTS

Compared with other children reported to POCC (n = 1,190), those in ALL-MTN (n = 481) were less often hospitalized (23%
v
29%,
P
= .01) or admitted to the intensive care unit (ICU: 3%
v
5%,
P
= .01); these findings persisted in multivariable analysis (hospitalization: odds ratio [OR], 0.7 [95% CI, 0.6 to 0.9]; ICU: OR, 0.5 [95% CI, 0.2 to 0.8]). However, cancer-directed therapy was changed more often for children in ALL-MTN (50%
v
33%,
P
≤ .01; OR, 2.0 [95% CI, 1.6 to 2.5[). Vaccination was an independent prognostic factor in our multivariable model, decreasing odds of hospitalization (OR, 0.7 [95% CI, 0.5 to 0.9]).

CONCLUSION

Children in ALL-MTN required fewer hospitalizations and ICU admissions but more therapy modifications than other children with cancer. Vaccination against COVID-19 reduced the odds of hospitalization.
