Hypothesis
Is there a relationship between mdrl RNA expression in leukaemic cells and response to chemotherapy in acute leukaemia?
Conclusion
The expression of mdrl RNA is common in acute untreated leukaemia, but it does not significantly increase the proportion of leukaemic cells that express it after chemotherapy.
Supporting Evidence
- 20 out of 44 patients with de novo untreated AML had detectable mdrl RNA.
- 12 of 18 patients with detectable mdrl RNA levels achieved complete remission.
- Remission duration tended to be longer among patients with undetectable mdrl RNA.
Takeaway
This study looked at how much of a certain gene, called mdrl, is found in leukaemia cells. They found that many leukaemia patients have this gene, but it doesn't really help them get better with treatment.
Methodology
The study used a quantitative RNA-RNA solution hybridisation method to measure mdrl RNA transcripts in leukaemic cells.
Limitations
The study included patients treated with different chemotherapy protocols, which may affect the interpretation of results.
Participant Demographics
The study included 76 patients with acute leukaemia, with a median age of 66 years.
