Brief Summary

The Young Survivors at Kantonsspital Aarau project assesses the prevalence and severity of late effects in survivors of childhood and adolescent cancer according to the modified CTCAE criteria prospectively. The clinical data are generated during regular follow-up care visits, the collection starts directly after completion of treatment and is longitudinally.

Detailed Description

Background:

Around 250-300 children and adolescents below the age of 21 years are newly diagnosed with cancer in Switzerland every year. Research led to remarkable progress in survival in the last decades. The 10-year survival rate in Switzerland is currently 87%. Previous research showed that, depending on the treatment exposure, a high proportion of these survivors suffer from chronic medical conditions, so called late effects.

Many studies on late effects in former childhood cancer patients are based on retrospective data. However, this type of study design has unavoidable limitations, such as missing data, different coding and grading of severity of late effects, and the assessment at different time points. Therefore, we need prospectively collected data, including severity coding in a standardized way, to overcome these limitations.

Objectives:

The overarching aim of "Young Survivors at Kantonsspital Aarau, Switzerland" is to assess late effects in childhood cancer survivors prospectively and in a standardized way. These data will contribute to the increasing knowledge on long-term outcomes and late effects in the future. This new knowledge is important in order to be able to adapt and improve long-term follow-up care. In the longer term, survivors will benefit from this extensive and prospective data collection.

Methods:

"Young Survivors at Kantonsspital Aarau" has a registry-like design. Data produced during regular follow-up visits are collected in a comprehensive database and in a standardized way. We collect all information generated prospectively from start of the study onwards and retrospectively until January 2016. From 2016 onward, all medical records are kept electronically. We classify and grade the severity of late effects according to the modified National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE v4.03). The outcome variables correspond to results from risk-stratified organ examinations, which are performed according to the Children's Oncology Group guidelines v5.0. The exposure variables correspond to information from the patients' medical history, including detailed information on cancer diagnosis and treatment. The data will be analyzed in an exposure- or organ system-driven approach. We start recruitment with patients diagnosed and treated at the Kantonsspital Aarau. The design of the study allows the inclusion of other clinics in the future.

Research and significance:

Research on late effects of former childhood cancer patients often relies on retrospective data collection, which is associated with unpreventable limitations. "Young Survivors at Kantonsspital Aarau" overcomes these limitations and additionally grades the severity of late effects in a standardized way. This allows us to analyze changes in severity of late effects over time, within and between survivors. This information will increase our knowledge on late effects and contribute to long-term follow-up care.
