Abstract
The incidence of skin cancer (e.g., squamous cell carcinoma, basal cell carcinoma, and melanoma) has been increasing over the past several years. It is expected that there will be a parallel demand for cutaneous tumor samples for biomedical research studies. Tissue availability, however, is limited due the cost of establishing a biorepository and the lack of protocols available for obtaining clinical samples that do not interfere with clinical operations. A protocol was established to collect and process cutaneous tumor and associated blood and saliva samples that has minimal impact on routine clinical procedures on the date of a Mohs surgery. Tumor samples are collected and processed from patients undergoing their first layer of Mohs surgery for biopsy-proven cutaneous malignancies by the Mohs histotechnologist. Adjacent normal tissue is collected at the time of surgical closure. Additional samples that may be collected are whole-blood and buccal swabs. By utilizing tissue samples that are normally discarded, a biorepository was generated that offers several key advantages by being based in the clinic versus the laboratory setting. These include a wide range of collected samples; access to de-identified patient records, including pathology reports; and, for the typical donor, access to additional samples during follow-up visits.
