Hypothesis

Can fine needle aspiration (FNA) accurately assess p53 protein expression in breast cancer compared to resected tissue?

Conclusion

FNA provides sufficient protein for Western blotting studies and can be used to monitor p53 activity in breast cancer during treatment.

Supporting Evidence

  • FNA was shown to provide adequate protein for up to 5 Western blot studies.
  • p53 expression and phosphorylation did not differ significantly pre- and post-operatively.
  • The study confirmed that cancer cells accounted for the protein expression detected on Western blots.

Takeaway

Doctors can use a small needle to take samples from breast cancer patients to check how well the cancer is responding to treatment.

Methodology

The study compared paired samples of breast cancer FNAs with tissue samples from surgical resection using Western blotting.
