Hypothesis

Is there a correlation between HER-2/neu and VEGF expression in colon cancer?

Conclusion

HER-2/neu and VEGF are not important prognostic markers of colon cancer.

Supporting Evidence

  • HER-2/neu expression was positive in 15.5% of samples.
  • VEGF expression was positive in 55.5% of samples.
  • HER-2/neu was correlated with tumor size and distant metastases.
  • VEGF was correlated with tumor size, stage, and metastases.
  • No significant correlation was found between HER-2/neu and VEGF expression.

Takeaway

This study looked at two proteins, HER-2/neu and VEGF, in colon cancer to see if they could help predict how the cancer behaves. It found that they don't really help with that.

Methodology

Immunohistochemical analysis of HER-2/neu and VEGF expression in tumor samples from 317 colon cancer patients.

Potential Biases

Potential biases in scoring immunohistochemical results.

Limitations

The study may not account for all variables affecting cancer prognosis.

Participant Demographics

317 patients, 187 men and 130 women, aged 21-86 (mean 57.8 years).
