Identifying genetic risks for complications in childhood cancer patients in Switzerland

Genetic Risks for Childhood Cancer Complications in Switzerland

Observational University Hospital, Geneva · NCT04702321

This study is trying to find out if certain genetic differences can help explain the complications that childhood cancer patients in Switzerland might face after their treatment.

What this trial studies

The GECCOS project aims to identify genetic variants linked to complications arising from childhood cancer treatments by analyzing germline genetic samples and clinical data from Swiss childhood cancer patients. This observational study utilizes data from the Germline DNA Biobank for Childhood Cancer and Blood Disorders in Switzerland, focusing on understanding how genetic differences can influence the severity and type of complications experienced by these patients. By correlating genetic information with clinical outcomes, the project seeks to enhance personalized care for childhood cancer survivors. This nationwide analysis has not been previously conducted in Switzerland.

Who should consider this trial

Good fit: Ideal candidates for this study are childhood cancer patients registered in the Swiss Childhood Cancer Registry who have consented to participate in the biobank.

Not a fit: Patients who do not have a genetic predisposition to complications or those who have not consented to the biobank will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved personalized treatment strategies for childhood cancer patients, minimizing complications and enhancing their quality of life.

How similar studies have performed: While this approach is novel in Switzerland, similar studies in other countries have shown success in linking genetic variants to treatment complications in childhood cancer.
