Study Summary

The purpose of this study is to study 50 patients with multiple Basal Cell Carcinoma (BCC) who will be receiving Photodynamic Therapy (PDT) as treatment for their tumors. This study wants to establish the optimal conditions for treating BCC tumors with PDT. Previous research suggests that taking Vitamin D prior to the start of PDT could help improve the effectiveness of the treatment in eliminating the BCC. Overall, this study will help establish oral Vitamin D3/PDT as a new combination therapy for skin cancer (BCC). Photodynamic Therapy (PDT) is an investigational (experimental) technique that works by combining a photosensitizing topical agent and an intense light source to kill tumor cells. PDT is currently approved for the treatment of BCC in Europe, Canada, and Australia. However, it is experimental in the United States because it is not approved by the Food and Drug Administration (FDA).

Primary Outcome

Change in tumor diameter per month. For each participant, the investigators will analyze the difference in tumor clearance between treatments, one with neoadjuvant D3+PDT, the other with PDT alone, and the other with or without D3 in order to establish a D3 replete state. The order of the first two treatments is randomized in case the assumption of a linear tumor clearance rate is incorrect The statistical significance of the difference in Delta-T after D3+PDT versus the difference in Delta-T a
