Results of a Multicenter Retrospective Study on Pediatric Brain Tumors in Italy

This retrospective study was undertaken to evaluate the clinical characteristics, course and treatment of children (0–14 years of age) diagnosed with a primary CNS tumor during the period 1976–1982 in Italy. Four hundred and sixty-two patients (263 males and 199 females) were followed by 18 various neurosurgical and pediatric oncology centers. The histologic types most frequently reported were: medulloblastoma (23 %), astrocytoma (16 %), ependymoma (11 %) and spongioblastoma (11 %). Of the 388 patients who underwent surgery, radical excision was reported in 42 %, partial excision in 32 %, biopsy only in 6 %, and unqualified surgery in 4 %; 19 % had no surgery. Radiotherapy and chemotherapy combined were administered in 61 % of the 143 patients followed at pediatric oncology centers; 19 % received radiotherapy alone, 3 % chemotherapy alone, and 17 % neither treatment. Forty-six percent of the patients were reported alive, 40 % dead, and 14 % lost to follow-up. Performance status was identified for 62 patients. The investigation revealed marked differences in the therapeutic treatment administered, thus precluding valid data analysis. This emphasizes the need to coordinate efforts among the institutions and the disciplines involved in the treatment of this form of childhood cancer.
