Pediatric nasopharyngeal cancer with repeated oligometastases involving the bone, liver and distant lymph nodes who achieved cure after radiotherapy

摘要

Systemic chemotherapy is a standard treatment for Stage IVc nasopharyngeal carcinoma (NPC). Stage IVc NPC patients with oligometastases have a better prognosis, and local therapy has an important role in further development of the disease. However, the efficacy of local therapy to the metastases in patients with multiple-site and/or multiple-organ metastases is limited due to the aggressive behavior of the tumor. We report a NPC case in a pediatric patient with repeated oligometastases involving the bone, liver and distant lymph nodes who achieved 10-year disease free status after initial chemotherapy and radiotherapy to all the metastases. This very rare case demonstrated that radiotherapy to oligometastatic lesions have a potential to cure repeated oligometastases which involved multiple-organ metastases in a pediatric NPC with stage IVc.
