Introduction:
In recent years much progress has been made in the therapy of chronic lymphocytic leukaemia, as the new innovative medicine proved to be effective in managing patients carrying TP53 abnormalities. To identify all these patients, it is essential to screen for both forms of TP53 defects, including both 17p deletions and TP53 mutations.
Aim:
The aim of this study was to determine the frequency of TP53 mutations and their association with 17p deletions in a large Hungarian cohort of 196 patients suffering from chronic lymphocytic leukaemia.
Method:
We performed mutation analysis of TP53 (exons 3-10) using Sanger sequencing.
Results:
TP53 mutations were present in 15.8% of patients, half of which were associated with 17p deletion. By analysing both forms, TP53 defect was identified in 25.4% of the patients.
Conclusions:
Our study demonstrates that by performing a TP53 mutation analysis, an additional 10% of high-risk patients can be detected. Orv. Hetil., 2017, 158(6), 220-228.
