Metvix PDT in Participant With "High Risk" Basal Cell Carcinoma

Prospective, open, multicenter study. The high risk BCC lesions were treated with Metvix cream. A biopsy confirming the diagnosis of each BCC lesion should have been taken within 6 months prior to treatment. The participants was receive one or two treatment cycles each consisting of two Metvix PDT treatments 7 days apart (Lesions that did not respond completely after three months received a second PDT treatment cycle). The primary end-point was the histologically confirmed complete response rate within a participant (No BCC cells in the biopsy taken 3 months after the last treatment).
