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. Source: BCR — *Cancer in Belgium - metadata*, version 2, 2025-05-05.
Age of the patient at the time of incidence of the tumour, expressed in completed years.
Specific age category of the patient at incidence (BCR-defined classification).
Region of the official residence of the patient at the time of incidence of the tumour.
Most reliable method by which the diagnosis was made.
ICD-10 code of the histology, as a string.
ICD-10 expressed as a numeric code, derived by BCR from the registered topography/morphology combination because ICD-10 is not registered by the sources.
Organ or tissue from which the primary tumour originated (ICD-O-3 topography).
Histology of the tumour (ICD-O-3 morphology).
Behaviour of the tumour (ICD-O-3 behaviour code: benign, borderline, in situ, malignant, etc.).
Degree of resemblance of the tumour cells to the original tissue (differentiation grade).
Laterality of the tumour (e.g. left, right, bilateral, midline, not applicable).
Extent of the primary tumour based on evidence acquired before treatment (cT).
Absence or presence and extent of regional lymph node metastasis based on evidence acquired before treatment (cN).
Absence or presence of distant metastasis based on evidence acquired before treatment (cM).
Clinical prognostic stage group (cls_cg)
Combination of clinical TNM categories into prognostic groups.
Clinical main prognostic stage (cStadkort)
Combination of clinical TNM categories into main prognostic groups.
Indicates whether the patient has received neoadjuvant therapy prior to surgical / pathological staging.
Extent of the primary tumour based on evidence acquired before treatment, supplemented or modified by additional evidence acquired from surgery and pathological examination (pT).
Absence or presence and extent of regional lymph node metastasis based on evidence acquired before treatment, supplemented or modified by additional evidence acquired from surgery and pathological examination (pN).
Absence or presence of distant metastasis based on evidence acquired before treatment, supplemented or modified by additional evidence acquired from surgery and pathological examination (pM).
Pathological prognostic stage group (cls_pg)
Combination of pathological TNM categories into prognostic groups.
Pathological main prognostic stage (pStadkort)
Combination of pathological TNM categories into main prognostic groups.
Final, consolidated stage based on the clinical stage and the pathological stage.
Final, consolidated stage based on the first-level clinical stage and the first-level pathological stage.
International Classification of Childhood Cancer, third edition (Birch-Marsden categorical code).
Birch-Marsden classification expressed in numeric format.
Total malignant tumours of patient (totaltum)
Total number of malignant tumours of this patient.
Sequence place of this tumour (multiple)
Place of this tumour in the sequence of malignant tumours of the patient.
Breast tumour sequence indicator (borsttelling)
Indicates if the breast tumour is the first primary breast tumour of this patient or a subsequent breast tumour.
Indicates whether the patient is alive, deceased, or lost to follow-up.
Most recent date among the patient's vital-status dates (last alive date, date of death, lost-to-follow-up date).
Date on which it was last confirmed that the patient was alive.
Most recent value of the sample date(s), or the date the patient moved abroad.
