Inclusion Criteria
  • Patient must have biopsy proven high-grade (severe) dysplasia, carcinoma-in-situ or early stage adenocarcinoma;
  • Patient may have received prior therapy; e.g. Nd-YAG laser, radiation therapy or chemotherapy. At least one month must have elapsed between prior treatments and PDT.
  • Tumors can be primary or recurrent, Stage 0 or I, N0M (any).
  • Patients must have no contraindications to endoscopy.
  • Male or female patients must be 18 years old or older. Female patients must not be pregnant and must be practicing a medically acceptable form of birth control or be sterile or post-menopausal. A pregnancy test is required and must be negative.
  • Patients must sign an Informed Consent according to FDA guidelines and be acceptable to the RPCI IRB.
  • Patients must have a Karnofsky status 50 or above.
  • Operable patients are not excluded.
Exclusion Criteria
  • Patients with tumors of grade greater than T-1.
  • Porphyria or hypersensitivity to porphyrin or porphyrin-like compounds.
  • WBC <2,000; platelet count <50,000, prothrombin time 1.5 times above the upper normal limit.
  • Patients with impaired renal and/or hepatic function (total serum bilirubin >3.0 mg/d, serum creatinine >3 mg%, alkaline phosphatase (hepatic) or SGOT >3 times the upper normal limit.
  • Patients on concurrent chemotherapy or radiation therapy will be excluded as well as those having received prior treatment for the esophageal cancer within 4 weeks of enrollment.
  • If the patient has cancer other than non-melanoma skin cancer they must be deemed disease free by their treating physician.
