Hypothesis
The study evaluates the effectiveness of photodynamic therapy utilizing YAG-OPO laser for treating early stage lung cancers.
Conclusion
Photodynamic therapy using YAG-OPO laser is effective in achieving complete remission in early stage lung cancers.
Supporting Evidence
- Complete remission was achieved in 82.6% of the lesions treated.
- Partial remission occurred in 13.8% of the lesions.
- No change was observed in 3.4% of the lesions.
- Patients were treated with a YAG-OPO laser after receiving Photofrin.
- The study included patients with histologically proven early stage lung cancer.
- All cases were squamous cell carcinoma.
- The therapy was well tolerated with no serious adverse effects.
Takeaway
Doctors used a special light therapy to help patients with early lung cancer, and it worked really well for most of them.
