About this study
Official title: Swiss Childhood Cancer Survivor Study (SCCSS)
The SCCSS is designed to investigate which long-term effects childhood cancer and its treatment have on survivors, and includes those who were under 20 years when they were diagnosed. The SCCSS explores childhood cancer survivors' quality of life, the health care received by childhood cancer survivors during follow-up care, the effects of medication, somatic and psychosocial health issues, how childhood cancer survivors take care of their own health including health behaviors, and also collects demographic details like family background, education and profession. To learn more about these topics, the investigators send questionnaires to childhood or adolescent cancer survivors. The investigators use the results to inform physicians and patients, and to improve treatment of childhood cancer and follow-up.

The SCCSS is designed to investigate which long-term effects childhood cancer and its treatment have on survivors, and includes those who were under 20 years when they were diagnosed. The SCCSS explores childhood cancer survivors' quality of life, the health care received by childhood cancer survivors during follow-up care, the effects of medication, somatic and psychosocial health issues, how childhood cancer survivors take care of their own health including health behaviors, and also collects demographic details like family background, education and profession. To learn more about these topics, the investigators send questionnaires to childhood or adolescent cancer survivors. The investigators use the results to inform physicians and patients, and to improve treatment of childhood cancer and follow-up.
Background: Therapies have improved so much in the past decades that more than 80% of children and adolescents now survive cancer. This means that the population of long-term childhood cancer survivors is growing. Since cancer and its treatments may later have adverse effects, it is important to track and improve survivor health and quality of life. Comprehensive data on the burden of late effects of childhood cancer or risk factors for late effects was not available, and so Switzerland set up the SCCSS to increase knowledge and improve the quality of care and follow-up.
Objectives: The SCCSS investigates long-term outcomes of survivors of childhood and adolescent cancer, and the incidence and spectrum of various somatic and psychosocial outcomes including late mortality, second primary malignancies, somatic health and medication, mental health, educational achievements, health-related quality of life, and the association of these outcomes with risk factors like tumor, treatment modalities, and demographic characteristics. The SCCSS also investigates how health-care is provided, and how long-term childhood cancer survivors take care of their health inducing health behaviors.
Methods: All Swiss residents who were diagnosed with cancer at age <20 years, have survived at least 5 years since cancer diagnosis, received a detailed questionnaire. The investigators added data from general practitioners and hospital records. To compare survivors with the general population, they also send the questionnaire to the siblings of childhood cancer survivors. Since 2025 we ask participants of the SCCSS if they are interested in wearing an accelerometer for one week to track the amount of time they spend moving, sitting and sleeping (SCCSS-Activity).
Rationale and significance: The data collected by the SCCSS allows the investigators to study long-term outcomes of Swiss childhood cancer survivors. The SCCSS helps to learn more about the incidence of late effects and their risk factors. It also allows to summarize the current state of care in Switzerland. Since early diagnosis can prevent or mitigate many late effects, tracking them will help to improve the health of current and future childhood cancer survivors.
Current status of the SCCSS: From 2008-2026, the investigators have contacted 7867 childhood cancer survivors diagnosed between 1976-2019 and 2074 of their siblings. The investigators contact new 5-year childhood cancer survivors at regular intervals, and continuously analyse and publish data and findings. By 2022, the investigators have contacted 3443 childhood cancer survivors for a follow-up questionnaire and will continue with this at regular intervals.
Current status of the SCCSS-Activity: From 2025, the investigators have asked 369 participants of the SCCSS if they are interested in participating in the SCCSS-Activity.

What is being measured
The primary outcome is the main question the study is designed to answer.
Long-term outcomes of survivors of childhood and adolescent cancer
Incidence and spectrum of various somatic and psychosocial outcomes including describing the cause-specific long-term mortality, the number of patients with second primary malignancies and somatic health effects, and describe medication use, mental health status, educational achievements, and health-related quality of life of childhood cancer survivors as assessed by questionnaires and data from the Swiss Childhood Cancer Registry.
Measured: Baseline medical information and questionnaire data collection among those who survived at least 5 years, follow-up data collection at regular intervals (+/- every 5 years, 40 years) afterwards.
Secondary outcomes (1)
Risk factors of long-term outcomes of survivors of childhood and adolescent cancer
Association of long-term outcomes with risk factors like tumour, treatment modalities, and demographic characteristics as assessed by questionnaires and data from the Swiss Childhood Cancer Registry.
Measured: Baseline medical information and questionnaire data collection among those who survived at least 5 years, follow-up data collection at regular intervals (+/- every 5 years, 40 years) afterwards.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The SCCSS is designed to investigate which long-term effects childhood cancer and its treatment have on survivors, and includes those who were under 20 years when they were diagnosed. The SCCSS explores childhood cancer survivors' quality of life, the health care received by childhood cancer survivors during follow-up care, the effects of medication, somatic and psychosocial health issues, how childhood cancer survivors take care of their own health including health behaviors, and also collects demographic details like family background, education and profession. To learn more about these topics, the investigators send questionnaires to childhood or adolescent cancer survivors. The investigators use the results to inform physicians and patients, and to improve treatment of childhood cancer and follow-up.

What does the primary outcome measure?
Long-term outcomes of survivors of childhood and adolescent cancer (time frame: Baseline medical information and questionnaire data collection among those who survived at least 5 years, follow-up data collection at regular intervals (+/- every 5 years, 40 years) afterwards.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03297034, which also lists 76 linked publications.
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2026.
