AKT Activation in Breast Cancer and Its Impact on Treatment Outcomes
Author Information
Author(s): Pérez-Tenorio G, Stål O
Primary Institution: Linköping University
Hypothesis
The study aimed to determine whether the expression and activation of Akt-1 are related to prognostic markers and survival in breast cancer patients treated with endocrine therapy.
Conclusion
The activation of Akt may have prognostic relevance in breast cancer, as pAkt positive patients were more prone to relapse with distant metastasis.
Supporting Evidence
- pAkt was associated with lower S-phase fraction (P=0.001).
- pAkt positive patients were more prone to relapse with distant metastasis (P=0.004).
- Heregulin β1 was found mainly in oestrogen receptor negative cases (P=0.026).
- Heregulin β1 expression was inversely associated with lymph node status (P=0.005).
Takeaway
This study found that a protein called pAkt can help predict if breast cancer patients will have a relapse after treatment.
Methodology
The study analyzed the expression and activation of Akt-1 in breast cancer patients using flow cytometry and immunohistochemistry.
Limitations
The study may be undersized to detect significant differences in some associations due to the small number of tumors overexpressing erbB-2.
Participant Demographics
Patients were aged 35-49 years and treated with tamoxifen and/or goserelin.
