Hypothesis

Does a selective COX-2 inhibitor enhance the effects of radiotherapy on tumor growth and metastasis in a Lewis lung carcinoma model?

Conclusion

High dose celecoxib significantly inhibited tumor growth and reduced pulmonary metastases when combined with radiotherapy.

Supporting Evidence

  • Celecoxib treatment reduced tumor volume significantly compared to control.
  • High dose celecoxib led to fewer metastatic lung nodules.
  • Radiation combined with celecoxib showed a greater delay in tumor growth.

Takeaway

Giving a high dose of celecoxib helps shrink tumors and stop them from spreading when used with radiation treatment.

Methodology

Mice were injected with LLC cells and treated with different doses of celecoxib and radiation, then tumor growth and lung metastases were measured.

Limitations

The study was conducted in an animal model, which may not fully represent human responses.
