Abstract
A significant therapeutic effect of photodynamic therapy (PDT) is shown in a patient with extensive vulvar cancer after ineffective surgical and chemoradiotherapy. During the year, three courses of local PDT with a photosensitizer based on chlorin e6 were carried out. The photosensitizer was administered intravenously three hours before irradiation at a dose of 1.2 mg/kg. For laser irradiation (662 nm) of the vulvar tumor, a light guide for external irradiation was used: the power density was 0.2 W/cm2, the light dose was from 100 to 250 J/cm2. As a result of treatment, tumor regression and stable remission are observed. The patient remains under observation.
