Description
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 (HGD/CIS or early adenocarcinoma) can be primary or recurrent, Stage 0 or I N0M (any)
- Patients must have no contraindication 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.
- Patients with early invasive adenocarcinoma will be included only if they are considered poor surgical risks, have failed or refused XRT/chemo, or refused surgery.
- If the patients has had cancer other than non-melanoma skin cancer, their treating physician must deem them disease-free.
Exclusion Criteria:
- Patients with tumors of grade greater than T-1.
- Porphyria or hypersensitivity to porphyrin or porphyrin-like compounds
- WBC<4000; platelet count<100,000; prothrombin times 1.5 times above 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.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Optimal Light Dose
Time Frame: 24 hours
|
Using toxicity to normal surrounding tissue as a determinant and using two HPPH doses of PDT in HGD, CIS or early adenocarcinoma in Barrett's esophagus, to determine the optimal light dose at each HPPH dose
|
24 hours
|
Secondary Outcome Measures
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Toxicity to normal surrounding tissue
Time Frame: 24 hours
|
To determine the tocixity to normal surrounding tissue of treating at approximately 24 hours(21-26hr) post injection of HPPH
|
24 hours
|
|
Comparing HPPH to Photofrin
Time Frame: 5 years
|
To determine the length of time of cutaneous photosensitivity of HPPH compared to historical data on Photofrin
|
5 years
|
|
Effect of injection
Time Frame: 24 hours
|
To determine the effect of a 24 hours interval between injection of HPPH and light treatment
|
24 hours
|
|
Efficacy of Treatment
Time Frame: 5 years
|
A secondary objective is to determine efficacy of treatment at each set of paraments, i.e. ability to completely resolve the CIS, HGD or early cancer.
|

|
Resolve Barrett's mucosa
Time Frame: 5 years
|
An Additional secondary objective is to determine ability of PDT to resolve the Barrett's mucosa
