[Effect of S-1 in a patient with metastatic eyelid sebaceous carcinoma].

We report a 68-year-old female with a history of repeated right cervical lymph node metastasis secondary to eyelid sebaceous carcinoma. She had undergone right neck dissection due to lymph node metastasis at the department of surgery in an other local hospital. After the orbital exenteration, she underwent multiple operations, including 2 right partial parotidectomy and then total parotidectomy, 4 right cervical lymph node excisions and 1 left upper neck dissection due to lymph node metastasis. Adjuvant chemotherapy with S-1(at a dose of 80 mg per day)alone was applied as tumor dormancy therapy on an outpatient basis. Any adverse events during S-1 medication were observed. New metastatic lesions were not found until 29 months after the beginning of chemotherapy with S-1 alone. Although the effectiveness of S-1 for eyelid sebaceous carcinoma has not been demonstrated, S-1 might be useful in patients with recurrent eyelid sebaceous carcinoma based on our patient's recurrence-free survival.
