Malignant germ cell tumors in childhood: results of the first Italian cooperative study "TCG 91".
2003
Background and Aims About 20% of patients with germ cell tumor (GCT) are still resistant to therapy. To investigate which features are present in resistant patients, a multicenter study on GCT in children was undertaken to correlate clinical and laboratory parameters with the outcome. Methods Patients aged less than 16 years, with histologically proven extracranial GCT were included. Results Ninety-five patients (median age 33 months, 45 males) were eligible. The site of the primary tumor was gonadal in 59, extragonadal in 36. The stage was I in 39; II in 5; IIIa (microscopic residue) in 7; IIIb (macroscopic residue) in 16; IIIc (unresectable) in 13; IV in 15. The treatment was surgery alon…
Bax mutation and overexpression inversely correlate with immature phenotype and prognosis of childhood germ cell tumors
2007
Primary childhood germ cell tumors (GCTs) represent a rare and heterogeneous group of tumors that varies in histologic differentiation, age of presentation and clinical outcome. In malignant neoplasms, apoptosis is a prognostic marker and a predictive factor of response to therapy. Therefore, the study of the expression and mutation of molecules involved in the regulation of apoptosis could be useful in order to both predict the clinical outcome and design self-tailored therapeutic approaches. We retrospectively analysed tissue samples of 54 childhood GCTs. The expression of p53 and BAX protein was assessed by immunohistochemistry (IHC). Moreover, we investigated the presence of mutations i…
Teratoma with a malignant somatic component in pediatric patients: The Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) experience
2010
Background Teratoma with a malignant somatic component (TMSC) is rare but described in adults, whereas information on pediatric presentation is sparse. Procedure The Associazione Italiana Ematologia Oncologia Pediatrica identified 14 cases of TMSC. Clinical files and pathology specimens were reviewed. Results The series (9 female, 5 male) showed the following disease: testis (2), sacrococcygeal (3), ovary (3), retroperitoneum (3), mediastinum (2), and foot soft tissue (1). Distribution of the somatic component was: carcinoma (4), pancreatic neuroendocrine tumor (1), neuroblastoma (3), rhabdomyosarcoma (3), rhabdomyosarcoma plus liposarcoma, chondrosarcoma, neurogenic sarcoma (1), chondrosar…
