Stereotactic Radiotherapy Boost in Treatment of Persistent Periocular Sebaceous Carcinoma after Surgery

Sebaceous carcinoma is a rare malignancy that should be treated with surgical resection. Nonetheless, a dynamic and aggressive course of the disease may disqualify a patient from this treatment. Applying radiotherapy with the escalation dose using a stereotactic boost is worthy of consideration as a radical treatment. In this paper, we present the case study of a young patient with a tumor localized in the periocular area. The patient was treated with operation two times without a satisfactory effect. Conventional radiotherapy, 60 Gy in 30 fractions, combined with chemotherapy based on cisplatin 40 mg/m(2) and the addition of a stereotactic radiosurgery boost were administered. The tolerance of this treatment was acceptable. During the 2-year follow-up, local and distant recurrences were not diagnosed. The presented case shows the usefulness of an individualized approach in the radical treatment of sebaceous carcinoma with the use of the stereotactic radiotherapy boost. This is a subsequent example of the implementation of the boost in head and neck carcinoma, which yields a positive result.
