Hypothesis

How do ELISA and immunohistochemistry compare in detecting components of the plasminogen activation system in tumor tissues?

Conclusion

The study found that while both methods can indicate protein levels, they are not directly interchangeable and may have different clinical values.

Supporting Evidence

  • The study compared 33 cancer lesions of various origins using both ELISA and IHC.
  • Spearman correlation coefficients between IHC and ELISA results ranged from 0.41 to 0.78.
  • Higher IHC scores were associated with increased median ELISA values.

Takeaway

The researchers looked at two ways to measure proteins in cancer tissues and found that they don't always give the same results.

Methodology

The study compared protein expression levels in cancer lesions using ELISA and immunohistochemistry on adjacent tissue samples.

Limitations

The relationship between ELISA and IHC results was ambiguous for individual tumor cases.

Participant Demographics

The study included cancer lesions from various origins, including breast, lung, colon, cervix, and melanoma.
