Nonpharmacologic therapy »» surgery surgery is the primary treatment modality for all patients diagnosed with either bcc or scc. Full-thickness ablative procedure in the form of surgical excision of the tumor along with a margin of normal tissue surrounding the tumor is the preferred method for high-risk tumors. Obtaining negative surgical margins is critical for cure and decreasing the risk of tumor recurrence. A margin of 4 to 5 mm in well-defined bcc and scc ensures peripheral clearance in 95% of cases. Depending on the tumor size, degree of differentiation, and invasion of surrounding structures, larger margins of resection may be necessary. 46 the two most common surgical techniques used are electrodessication and curettage (ed&c) and mohs micrographic surgery (mms). The indications of each of these procedures are described below. Low-risk tumors defined as small, well-differentiated, and slow growing can be treated with superficial ablative techniques, including ed&c and cryotherapy. 46 ed&c is a simple, costeffective technique that uses repeated cycles of using a curette to cut through malignant tissue followed by electrodesiccation, which involves the application of high voltage, low current to the skin, causing drying or desiccation of the tissue. Ed&c is most appropriate for well-defined superficial lesions that are not located in areas with increased risk for metastasis. The disadvantage of this technique is that histologic confirmation of complete tumor removal is not possible. 48 this procedure is not recommended for treatment of recurrent disease, tumors of the face, and high-risk tumors. 48 chapter 93  |  skin cancer  1387 for high-risk nmsc or for tumors located in cosmetically or anatomically sensitive areas, mms is the procedure of choice. The goal of this therapy is complete removal of the cancer with preservation of as much surrounding normal tissue as possible. Mms involves careful dissection, staining of frozen sections, and anatomic mapping of the tumor specimen. Sections are assessed immediately under the microscope by the surgeon, and the process is repeated until a tumor-free margin is attained. Mms cures 93% of primary nmsc and 90% to 94% of recurrent disease compared with 92% and 77% cure rate with standard excision for primary and recurrent disease, respectively. 49 cure rates for all modalities decrease with the presence of high-risk features but are still superior with mms. 49 cryotherapy is a procedure used primarily for smaller, lowrisk nmscs with clearly defined margins. It involves delivering liquid nitrogen at subzero temperatures as a spray or with a supercooled metal probe to destroy the malignant tissue in a single cycle or multiple cycles. 48 this technique can achieve comparable results to conventional surgery for well differentiated, not too large, superficial tumors in older patients with bcc. 48 the procedure is contraindicated in the hair-bearing scalp, upper lip, and distal portion of lower leg because of delayed healing and high rates of recurrence. 48 »» radiation radiation is not standard therapy for the treatment of skin cancer. However, there are circumstances in which radiation may be preferred. It may be offered to patients in whom surgery is not possible because the tumor is inoperable or surgery would lead to unacceptable cosmetic or functional impairment. 49 radiation to the lip, ear, and nasal entrance for scc may provide the best cosmetic and functional result. On the other hand, some patients may develop dyspigmentation, radiodystrophy, or telangiectasia at the site of radiation, resulting in poorer cosmetic outcomes.
