Photochemical Tissue Bonding
Summary
The broad aim of this study is to evaluate the efficacy of photochemical tissue bonding (PTB) for the closure of skin excisions. We will test the hypothesis that full thickness skin excisions treated with PTB can heal with less scarring than those treated with the conventional suture closure method.
Description
Hypertrophic scarring is a frequent endpoint after traditional surgical excision of skin cancers of the chest. These scars create significant long-term morbidity to the patient. There is a clinical need for an alternative treatment that would reduce factors associated with hypertrophic and possibly keloid scar formation by providing minimal tension, low infection risk and an absence of foreign body material. This would result in a normal appearing and healed scar without associated patient morbidity. Photochemical tissue bonding may provide this alternate treatment. PTB differs from sutures by continuously joining the tissue surfaces on a molecular level rather than only at discrete suture points. In addition, PTB does not incite foreign body reactions nor create tissue injury during passage of the needle and tying a knot, injuries that may initiate scarring.

Medical and Biotech [MESH] Definitions
Mohs Surgery
A surgical technique used primarily in the treatment of skin neoplasms, especially basal cell or squamous cell carcinoma of the skin. This procedure is a microscopically controlled excision of cutaneous tumors either after fixation in vivo or after freezing the tissue. Serial examinations of fresh tissue specimens are most frequently done.
Carcinoma, Merkel Cell
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
Carcinoma, Basosquamous
A skin carcinoma that histologically exhibits both basal and squamous elements. (From Dorland, 27th ed)
Basement Membrane
A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers.
Carcinoma, Non-small-cell Lung
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
