Malignant germ cell tumors in childhood: results of the first Italian cooperative study "TCG 91".
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…
Teratoma with a malignant somatic component in pediatric patients: The Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) experience
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…
