A population based pediatric oncology registry in Southern Sweden: the BORISS registry

Abstract

A population based registry, with the acronym BORISS, was established. It contains all individuals (0–18 years of age at diagnosis) diagnosed with cancer from 1970–01–01 until 2016–12–31 in Southern Sweden. The treatment data has been entered into the registry after confirmation of the diagnosis by the Swedish national cancer registry and updates on vital status from the Swedish population registry. The number of individuals with a pediatric cancer diagnosed during these 46 years are 2928. Of these, 2065 are currently alive and 1882 individuals are 5-year survivors. Data on treatment and malignancy of the 5–year survivors has been collected from medical records and entered into the database. Treatment data contains surgical procedure, target organ of radiation therapy including dose and fractionation, and cytostatic treatment with dose (mg) per body surface area (m²) for all cytostatic agents. Data on individuals receiving stem cell treatment is included. The database is unique in that it is population based, contains all individuals and detailed treatment data on all 5-year survivors after childhood cancer in Southern Sweden since 1970. The database has contributed to several academic theses in the field of late effects after childhood cancer. BORISS also supports the Late Effect Clinic at Skåne University Hospital in Lund, Sweden with treatment details enabling a stratified surveillance.
