Our aim was to assess the efficacy of photodynamic therapy in inoperable patients with small esophageal carcinoma. Eleven patients were treated for squamous cell carcinomas ranging in size from 1 to 3 cm2. Hematoporphyrin (between 3 and 5 mg/kg) was injected intravenously and then the tumor irradiated at endoscopy 72 hours later with a dye laser (630 nm) at an energy of 250 joules/cm2. Complete destruction of the lesion was obtained in 6 cases with negative biopsies at 1 month. In all 6 patients, no recurrence was seen after a median follow-up of 4 months (range: 2-38). Partial destruction of the tumor was obtained in 4 cases while treatment was a complete failure in the last patient. Two instances of mild cutaneous photosensitization occurred. Two patients treated for recurrence after radiotherapy, died of esophageal perforation directly related to the procedure. Photodynamic therapy appears to be a possible effective treatment for esophageal squamous cell carcinoma in inoperable patients when other curative treatment modalities are not possible. |
