About this study

Official title: COVID-19 and Childhood Cancer - Diagnostic Delay, Survival, and COVID-19 Susceptibility

The investigators will first examine the impact of the COVID-19 pandemic on childhood cancer patients in Sweden and Denmark, both regarding susceptibility to severe COVID-19 among long-term childhood cancer survivors, and, for those diagnosed with childhood cancer during the pandemic, whether the path through primary care to cancer diagnosis as well as short-term survival has changed. Second, the investigators will study childhood cancer incidence before, during and after the pandemic with the particular aim to test the hypothesis regarding an infectious disease etiology for acute lymphoblastic leukemia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT06482281
Study groupRoleWhat they receive
Childhood cancer survivorsChildhood cancer cases (0-19 years old) reported to the national cancer registers from 1971 in Sweden and Denmark, who were alive five years after the cancer diagnosis
Matched comparisonsFive general population comparisons were randomly selected and matched to the childhood cancer survivors by sex and year of birth
SiblingsAll siblings of the childhood cancer survivors
Childhood cancer casesChildhood cancer cases (0-19 years old) reported to the national cancer registers from 2015 in Sweden and Denmark. They will then further divided in three groups: before the pandemic (2015-2019), during the pandemic (2020-2022), and after the pandemic (2022-)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Severe COVID-19

    Defined as:

    • death with COVID-19 listed as a cause of death
    • hospitalization, or admission to intensive care unit, because of COVID-19 (main diagnosis) or respiratory problems (main diagnosis) AND COVID-19 as secondary diagnosis

    Measured: Up to 3 years

  2. Childhood cancer survival

    Overall survival after a childhood cancer diagnosis

    Measured: After three and twelve months after the cancer diagnosis and three years after cancer diagnosis

  3. Number of contacts before childhood cancer diagnosis

    Number of healthcare contacts (including primary care) the year before the cancer diagnosis

    Measured: One year before cancer diagnosis

  4. Childhood cancer incidence

    Age standardized incidence rates for childhood cancer and cancer subtypes (particularly acute lymphoblastic leukemia) in Sweden and Denmark during and after the pandemic and compare it to the 5 years preceding the pandemic

    Measured: From 2015

What does the primary outcome measure?

Severe COVID-19 (time frame: Up to 3 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
