Retrospective Analysis of the Clinical Characteristics, Therapeutic Aspects, and Prognostic Factors of 18 Cases of Childhood Pineoblastoma.

Abstract:

BACKGROUND:Pineoblastoma is a rare malignant tumor of the pineal gland, which is more common in children. METHODS:We retrospectively reviewed 18 cases of pineoblastoma in children (10 girls), including general, clinical, and therapeutic information, and factors affecting prognosis. RESULTS:The median age of the children was 51.7 months (range, 19-156 months). Presenting symptoms included vomiting (64.70%), headache (47.06%), weak or unsteady walking (35.29%), and nausea (29.41%). Rarer symptoms (1 patient each) included limb rigidity, inability to speak, double vision, fever, and Parinaud syndrome. Five and 13 children, respectively, underwent subtotal and gross total resection; 5 and 13 children received adjuvant craniospinal irradiation therapy and chemotherapy. Two children received both craniospinal irradiation and chemotherapy. The 5-year overall survival of the patients was 27.8% (5/18). The survival rate of children older than 4 years (66.7%) was significantly higher than that of younger children (8.3%). The 5-year overall survival rate of boys (50.7%) was higher than that of girls (10.0%); that of children who underwent gross total resection (30.8%) was higher than that of children who underwent subtotal resection (20.0%); and that of children treated with adjuvant craniospinal irradiation (50.7%) was higher than that of those not given craniospinal irradiation (10.0%). However, in each of these 3 comparisons the differences were not significant. CONCLUSION:Pineoblastoma is rare but often fatal, especially in children younger than 4 years. Survival rates tend to be higher in boys, children undergoing gross total resection (rather than subtotal), and those given craniospinal irradiation.
