Radiation therapy is particularly useful in the management of patients with primary lesions that would otherwise require difficult or extensive surgery (e.g., lesions on the nose or ears).[22] Radiation therapy eliminates the need for skin grafting when surgery would result in an extensive defect. Cosmetic results are generally good, with a small amount of hypopigmentation or telangiectasia in the treatment port. Radiation therapy can also be used for lesions that recur after a primary surgical approach.[23]
Radiation therapy is avoided in patients with conditions that predispose them to radiation-induced cancers, such as xeroderma pigmentosum or basal cell nevus syndrome.
Evidence (radiation therapy):
As noted above, radiation therapy has been compared with excision in a randomized trial that showed better response and cosmesis associated with surgery.[14,15][Level of evidence B1]

In a single-center trial, 93 patients with BCC were randomly assigned to receive either EBRT (130 kV x-rays, dosimetry depending on lesion size) or cryotherapy (two freeze-thaw cycles with liquid nitrogen by spray gun). Patients with lesions on the nose or ear were excluded because the investigators felt that EBRT is the treatment of choice for tumors in these locations.[24][Level of evidence B3]

Radiation was superior to cryotherapy in local control at 2 years.

By 1 year, the recurrence rate was 4% in the radiation arm and 39% in the cryotherapy arm in a per-protocol analysis. The investigators did not perform a statistical analysis, but the authors of a systematic literature review calculated a relative risk of 0.11 in favor of radiation (95% CI, 0.03–0.43).[10][Level of evidence B3]
