Hypothesis
Is photodynamic therapy using YAG-OPO laser effective for treating superficial esophageal carcinoma?
Conclusion
Photodynamic therapy using PHE and YAG-OPO laser is effective as a curative therapy for superficial esophageal carcinoma.
Supporting Evidence
- All lesions showed a complete response after one session of PDT.
