The purpose of this study is to determine the safety and maximum tolerated dose of Photocyanine injection in photodynamic therapy of malignant tumor (especially skin cancer and esophageal cancer).
Projected accrual: A total of 18-24 patients will be accrued for this study.

|Skin Cancer Esophageal Cancer||Procedure: Photodynamic therapy||Phase 1|
Photocyanine injection is a type of cyanine compound, which was invented in Fuzhou university by Professor Chen; it's maximum absorption wave is 670 nm. Patients receive intravenous injection of Photocyanine injection, and 24 hours later, patients undergo photodynamic therapy.
Cohorts of 3-6 patients receive escalating doses of Photocyanine Injection and photodynamic therapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 1 of 3 patients experiences dose-limiting toxicity. Three additional patients are treated at the MTD.
After completion of study therapy, patients are followed for up to 2 weeks.

|Official Title:||Safety Study of Photodynamic Therapy Using Photocyanine Injection in Treating Patients With Malignant Tumors|
|Study Start Date :||March 2009|
|Estimated Primary Completion Date :||March 2010|
|Estimated Study Completion Date :||April 2010|
Experimental: Photocyanine injection
Patients receive intravenous injection of Photocyanine injection from dosage of 0.1 mg/kg,0.2 mg/kg,0.33 mg/kg,0.5 mg/kg to 0.6 6mg/kg till the dose-limiting effect occur.
Procedure: Photodynamic therapy
patient undergo Photocyanine Injection via venous infusion followed by photodynamic therapy with 670nm diobe laser 24 hours later
- Maximum tolerated dose [ Time Frame: one month ]
- Treatment efficacy as measured by computed tomography (CT) or magnetic resonance imaging (MRI) and endoscopy exam 3 weeks after the start of study treatment according to the Response Evaluation Criteria In Solid Tumors (RECIST) standard [ Time Frame: six weeks ]
