title: Hematoporphyrin derivative photochemotherapy of spontaneous animal tumors: clinical results with optimized drug dose.
abstract: Hematoporphyrin derivative (HpD) photochemotherapy was performed on 13 primary spontaneous tumors in dog and cat. The animals received an optimized drug dose of 5 mg/kg body wt i.v. 48 h before the first treatment with laser light at 631 nm. An evaluation of the clinical results is presented and discussed. Complete disappearance of the primary tumors was obtained in all cases with one or more light irradiations. Five cases presented recurrences that were cured with a further treatment. In 4 cases treated after surgical exeresis of the primary tumors, this therapy resulted in complete cure.
