Abstract

Since 1981, more than fifty spontaneous tumors of dogs and cats were treated by photodynamic therapy with hematoporphyrins in the surgery department of the University of Milan. Therapeutic results proved to be successful and promising in certain forms of cancer and will be compared in the future with the effectiveness of other photosensitizer drugs like phatolocyanines derivatives. Applied hematoporphyrins phototherapy methods included: (1) injection of hematoporphyrins derivative (HpD) and irradiation with laser light at 631 nanometers, using a Rhodamine B dye laser; (2) injection of the active component of hematoporphyrin derivative (DHE) and irradiation with a Rhodamine B dye laser; and (3) injection of DHE and irradiation with laser light at 628 nanometers using a gold vapor laser. More frequently treated tumor sites were oral and nasal cavities. Other localizations were mucous membranes of the glans and stomach. Nineteen histological types were diagnosed in treated tumors.
