What this trial studies

The SCCSS-FollowUp is a national, multicenter cohort study aimed at investigating the late effects experienced by childhood cancer survivors in Switzerland. This observational study collects data through clinical examinations, laboratory tests, functional assessments, and questionnaires to understand the prevalence and risk factors associated with these late effects. By standardizing follow-up care and assessing survivors longitudinally, the study seeks to minimize chronic diseases and improve the quality of life for this population. The findings will help inform healthcare strategies for managing the long-term health of childhood cancer survivors.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals who were diagnosed with cancer at age 0-20 years, have completed their treatment, and are currently residing in Switzerland.

Not a fit: Patients who are in a palliative or relapsed situation where no follow-up examinations are planned will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of late effects in childhood cancer survivors, enhancing their quality of life.

How similar studies have performed: Other studies have successfully investigated late effects in childhood cancer survivors, indicating that this approach is both relevant and necessary.
