Hypothesis

Is the concentration of group II phospholipase A2 in breast cancer tissues associated with their malignant potential?

Conclusion

Higher levels of M-PLA2 in breast cancer tissues are linked to worse survival outcomes.

Supporting Evidence

  • M-PLA2 concentration was significantly higher in patients with distant metastasis.
  • Patients with high M-PLA2 concentrations had shorter disease-free and overall survival.
  • M-PLA2 was found to be an independent prognostic factor for disease recurrence and death.

Takeaway

This study found that a certain enzyme in breast cancer tissues can help predict how aggressive the cancer is.

Methodology

M-PLA2 concentrations were measured in tissue extracts from breast cancer patients using a radioimmunoassay.

Limitations

The study may have optimistic results due to using the same dataset to determine the cut-off point.

Participant Demographics

Patients who underwent mastectomy for breast cancer between 1982 and 1987.
