Hypothesis

This study investigates the expression of cytochrome P4501A in human breast carcinoma.

Conclusion

The study found that 39% of breast cancer tumors expressed cytochrome P4501A, which was not present in adjacent non-neoplastic tissue.

Supporting Evidence

  • 39% of breast tumors showed positive immunoreactivity for cytochrome P4501A.
  • The expression was only found in invasive carcinoma areas.
  • There was no expression of cytochrome P4501A in adjacent normal breast tissue.

Takeaway

In some breast cancer cells, a special protein called cytochrome P4501A is found, which isn't in the normal breast tissue nearby.

Methodology

The expression of cytochrome P4501A was assessed using immunocytochemistry on breast carcinoma samples.

Limitations

The study did not perform oestrogen receptor assays on all tumors and lacked information on some patients' smoking habits.

Participant Demographics

Patients aged 31-80, with a mix of tumor grades and smoking statuses.
