Projected accrual: A total of 18-24 patients will be accrued for this study.
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.

Karnofsky, an American specialist in cancer chemotherapy.
A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
