| Summary: | Radiotherapy is often used to treat lentigo maligna. However, the long-term efficacy and safety of radiotherapy approaches have not been thoroughly evaluated. We aimed to evaluate the long-term efficacy and safety of ultrasoft X-ray/Grenz ray treatment in those patients. A total of 161 lesions from 159 patients received treatment with Grenz ray between 2005 and 2007. Follow-up of recurrence was performed 10 years after the final treatment. In the study setting, the cure rates were 97% for primary therapy with Grenz ray alone and 100% when Grenz ray was combined with partial or radical excision. The treatment is well tolerated, simple to perform, and has an excellent cosmetic outcome, with 94% of patients pleased with the results. Grenz ray is painless, effective, and safe for use when surgery is not feasible. Thus, Grenz ray can be considered as a standard treatment option for lentigo maligna. |
