Clinical features and prognosis of intracranial embryonal tumors in children / 中国肿瘤临床

ABSTRACT

Objective: To investigate the clinical features and prognosis of intracranial embryonal tumors in children. Methods: Clinical data of 27 patients with intracranial embryonal tumors who were admitted to Beijing Shijitan Hospital, Capital Medical University be-tween May 2011 and December 2018 were retrospectively analyzed. Results: The study included 27 patients, comprising 17 male and 10 female children, with a median age of 7 years. Twelve patients underwent gross total resection, and 15 patients underwent subto-tal resection. After surgery, all 27 patients underwent craniospinal irradiation. The dose of craniospinal irradiation was 27-30.6 Gy, and the dose of the tumor bed was 55.8-60 Gy. Twenty-two patients underwent chemotherapy regimen composed of irinotecan, vtncris-tine, etoposide, nedaplatin after radiotherapy. The median follow-up period was 22 (4-93) months. Nine patients are alive without lo-cal or distant recurrence. Eighteen patients died; the causes of death were intracranial recurrence and spinal cord metastasis. The 1-, 3-, and 5-year survival rates were 79.4%, 50.2%, and 36.5%, respectively. Conclusions: Intracranial embryonal tumors in children are rare and malignant and can metastasize along the neuroaxis. Surgery, adjuvant radiotherapy, and chemotherapy are important for pa-tients with intracranial embryonal tumors. Moreover, the prognosis is poor.
