Photodynamic therapy of early esophageal cancer

Summary In 1992–2006 at P.A. Hertsen Moscow Oncology Research Institute photodynamic therapy (PDT) was performed in 48 esophageal cancer patients (total 48 lesions). For PDT we used Russian photosensitizers (Photogem, Photosens, Radachlorin, Alasens), Russian diode lasers (Crystall) and endoscopic equipment. As a result of PDT complete regression was in 77% of esophageal cancer lesions, partial regression was in 23%. The follow-up period was 3–11 years. Median of survival was in 4.59 years of esophageal cancer patient.
