title: Nasopharyngeal cancer with neck recurrence at 8 years and a lung metastasis at 15 years after the first definitive radiotherapy: a case report.
abstract: We report a patient with nasopharyngeal cancer with long-term follow-up of more than 16 years after the first course of radiotherapy in 1981. He developed a lung metastasis in 1996 after having a second course of radiotherapy for neck recurrence in 1989. The patient was a 42-year-old man with a nasopharyngeal tumor and a fixed upper neck metastasis (T1N1M0), which was treated with definitive radiotherapy. He manifested regional recurrence, at the margin of the radiation portal, with an 8 year disease-free interval, which was treated successfully by definitive re-irradiation. He developed a solitary lung metastasis, which was treated by video-assisted thoracoscopic lung resection, 7 years disease-free after the second course of radiotherapy. For 20 months after the removal of the lung metastasis he has been generally well without any signs of recurrence of sequelae. This case indicates the efficacy of definitive re-irradiation for regional recurrence and the necessity for long-term observation after radiation therapy for nasopharyngeal cancer.
