BACKGROUND: @entity33 ( @entity33 ) and photodynamic therapy have been proposed as treatments for early stage @entity5 . @entity33 is limited by its focal nature whereas photodynamic therapy is dependent on precise staging. The combination of @entity33 and photodynamic therapy were studied in the treatment of superficial @entity5 in @entity1 with @entity355 . METHODS: Seventeen consecutive nonsurgical @entity1 with superficial @entity5 underwent @entity33 followed by photodynamic therapy with a @entity7170 photosensitizer. Photoradiation was performed at 630 nm for a total dose of 200 J/cm of diffuser. RESULTS: Seventeen @entity1 (15 @entity1 ; mean age 69 +/- 13 years) underwent @entity33 . The mean diameter of mucosal resection was 1 cm. The margins were involved by @entity5 in 3 cases. @entity33 improved staging in 8 @entity1 (47%). Sixteen (94%) @entity1 remained in remission (median follow-up 13 months). Complications included @entity548 after @entity33 in 1 @entity1 (6%), stricture in 5 (30%), cutaneous @entity6337 in 2 (12%), and @entity4710 in 1 @entity1 (6%). CONCLUSIONS: Combined @entity33 and photodynamic therapy appears to be an effective and safe therapy for superficial @entity418 within @entity355 . This combination improves @entity5 staging, removes the superficial @entity5 , and eliminates remaining mucosa at risk for @entity5 development.
