The variables are different according to the type of tumour that is registered. Here is an overview of the available variables. The lists for each type of tumour are available for download in the section "National histology protocols" in the source website link.

PALGApatiëntnr Ascending patient number that is recreated for each request. The concept of 'patient' is based on equality of name (first 4 letters), date of birth, and gender.
PALGAexcerptnr Chronological numbering of excerpts within a patient.
Selectie Method of selecting the excerpts (most common example: 1 = target selection excerpt, 3 = history excerpt).
Kans_admin_meerling The likelihood that excerpts assigned the same PALGA patient number are not from the same patient (ranging from none to present-real, and depending on the amount of available information per excerpt).
Datum ontvangst Date of receipt of PA material at the PA department.
Soort onderzoek Type of examination (T=histology, C=cytology, B=population cytology, S=autopsy).
Geslacht Gender of patient.
Leeftijd Age of patient at the time of receipt of PA material at the PA department.
