  v: Logical model of a single cancer case as published in the Belgian Cancer Registry (BCR) **research dataset** ("Cancer in Belgium"). This is the *exported, derived* dataset — patient demographics are pseudonymised, several fields are derived (numeric ICD-10, age categories, region, vital-status dates), and tumour-sequence variables are computed registry-wide. For the **submission form** that hospitals fill in for every new diagnosis, see `BCRCancerRegistrationForm` (Bijlage 55), which is the upstream source of most of the variables here.
