It has been agreed by the UKACR working group that ‘T-cell granular
lymphocytic leukaemia’ should remain as a malignant behaviour /3 when
ICDO-3 is implemented (not as listed in the ICDO-3 book). This is in
line with WHO and ENCR classifications.

All staff need to update their ICDO-3 book to reflect the change of behaviour in line with the above recommendation.
