Hypothesis
Is aryl hydrocarbon hydroxylase activity a new prognostic indicator for breast cancer?
Conclusion
High AHH activity in breast cancer tissue predicts a poor prognosis for the disease.
Supporting Evidence
- The median AHH activity was significantly lower in benign tumors compared to malignant ones.
- Patients with low AHH activity had a significantly higher survival rate than those with high AHH activity.
- AHH activity correlated positively with axillary lymph node status.
Takeaway
This study found that measuring a specific enzyme in breast cancer tissue can help predict how well patients will do.
Methodology
AHH activity was measured in breast tumors from 188 patients, and survival was followed for 4 years.
Limitations
The study had a small sample size for recurrent cancer patients, which may limit the generalizability of the findings.
Participant Demographics
Patients included 18 with benign tumors, 153 with primary breast carcinoma, and 17 with recurrent cancer.
