Abstract

Background: Germ cell tumors are neoplasms that originate from multi potential germ cells and can be intra or extra gonadal. According to pathologic classification, they have different subtypes. They account for 3% of pediatric malignancies and most commonly happen in children before the age of 15 years old. Epidemiologic evidence about pediatric germ cell tumors is scant in our region. Objectives: The aim of current study was to determine demographic characteristics, recurrence and survival rate of germ cell tumor patients under the age of 21 years. Patients and Methods: During a 10-year period (1996 - 2006), 106 patients under the age of 21 years suffering from germ cell tumor were admitted to our centers. We extracted the data needed for our study from patients’ medical records in the hospitals. Results: Thirty seven boys and 69 girls with a mean age of 8.4 ± 7.8 years were included. Most tumors were diagnosed before the age of one year (37%). The most common pathologic subtype was mature teratoma (44%). Ovary (35%) was the most common primary site. Surgery plus chemotherapy were used to treat 54 patients and BEP was the most common chemotherapy regimen. Metastasis and recurrent tumor were seen in 22% and 8% of cases, respectively. Four-year overall survival was 89%. Conclusions: Our study showed that demographic characteristics of GCT patients in our population are similar to patients of other geographic regions in the world. Primary tumor site, histologic subtype and metastasis were significant prognostic factors for survival. © 2015, Iranian Journal of Cancer Prevention.
