Hypothesis
Are p53 mutations present at relapse in acute leukaemia and can they be detected at presentation?
Conclusion
The study found that p53 mutations are present in some patients at relapse of acute lymphoblastic leukaemia and can be detected in a minor clone at presentation.
Supporting Evidence
- p53 mutations were found in 7 out of 55 cases at relapse.
- The frequency of p53 mutations was higher in relapsed acute lymphoblastic leukaemia compared to acute myeloblastic leukaemia.
- In 5 out of 7 cases, presentation samples were available for analysis.
Takeaway
This study looked at whether a specific gene mutation is present when leukemia comes back, and found that it can sometimes be seen even before the leukemia relapses.
Methodology
Bone marrow samples from 55 patients were analyzed for p53 mutations using direct sequencing and allele-specific PCR.
Participant Demographics
The study included both adults and children with relapsed acute leukaemia.
