Abstract
Background: Germ cell tumor (GCT) account for approximately 2-3% of all malignancies in childhood. About 20% of patients with GCT are still resistant to therapy.
Methods: This study was undertaken on 57 patients with Germ cell tumor who were admitted to Ali Asghar Children’s Hospital during 1990-2004. Through this study, information about sex, age type of pathology, clinical sign, treatment and survival (5-year period) was gathered in order to have better treatment and follow up. This study was carried out as across-sectional survey and the obtained data was analyzed via Spss 10 soft ware.
Results: The findings showed that the mean age of patients was 4/9 ± 0/1 (1mo -14y), male 54%, female 46%, male/female, ratio=1/1. Site of tumor: saccrococcygeal 57/8 %( 33), gonadal 42% (24). Pathological type is yolk sac 61/4% (35), dysgerminoma 12/2% (7), malignant teratoma 14% (8), embryonal carcinoma 10/5% (6). The most common clinical sign were buttock mass 31/5% (18), abdominal pain 10/5% (6), abdominal mass 17/5%(10), testicular mass 28% (16). All of the patients were treated with chemotherapy (bleomycine, vinblastin, cisplatinum) mean of duration follow up were 48/4 months. In all of patients 31/5% (18) of the cases were alive and 70% (40) of patients were relapse and 15/7% (9) no information, 52/6% (30) of cases were expired. Five years survival of patients was 62%.
Conclusion: The analysis of the patients treated shows that extragonadal location of primary tumor (specially sacrococcygeal), level of AFP above 10 ng/ml in patients ,6 or more months of age and metastatic disease were the most unfavorable factors for overall survival.
