This study revisited the Dohner prognostic hierarchy in a cohort of 1585 well-documented patients with chronic lymphocytic leukaemia. The duration of both time to first treatment (TTFT) and overall survival (OS) were significantly longer than observed previously, and this is at least partly due to improved therapeutic options. Deletion 13q remains the most favourable prognostic group with median TTFT and OS from fluorescence insitu hybridization (FISH) testing of 72months and >12years, respectively. Deletion 11q had the poorest median TTFT (22months) and 17p deletion the poorest median OS (5years). The percentages of abnormal nuclei were significantly associated with differential TTFT for the trisomy 12, 13q and 17p deletion cohorts but not for the 11q deletion cohort. From the date of the first FISH study, patients with >85% 13q deletion nuclei had a notably shorter TTFT (24months). Patients with 20% 17p deletion nuclei had longer median TTFT and OS from the date of the first FISH study (44months and 11years), and were more likely to be IGHV mutated.
