Malignant ovarian germ cell tumors in pediatric patients: The AIEOP (Associazione Italiana Ematologia Oncologia Pediatrica) study.
2017
Objective Malignant ovarian germ cell tumors (MOGCT) carry an excellent prognosis, and the treatment aims to achieve results with the least possible treatment-related morbidity. The aim of this study was to assess the outcomes of pediatric patients with MOGCT. Methods Patients were treated according to their stage: surgery and surveillance for stage I; a modified bleomycin–etoposide–cisplatin (BEP) regimen for stages II (three cycles), III, and IV (three cycles) with surgery on residual disease. Results Seventy-seven patients were enrolled (median age 11.8 years), 26 with dysgerminoma (Dysg), 13 with immature teratoma and elevated serum alpha-fetoprotein levels (IT + AFP), and 38 with nondy…
Testicular tumors in childhood: a national report
1993
The authors report preliminary data of an Italian multicentric, retrospective study of primary testicular tumors (PTT) in childhood involving 20 Italian departments of pediatric surgery. Forty cases of PTT were observed during a 10-year period (1977–1987), with yolk-sac tumors being the most frequent (45%). Most testicular tumors were first perceived as a unilateral testicular mass. Scrotal ultrasonography represents the main diagnostic investigation, together with serum marker levels.
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…
IL TERATOMA ED IL CHIRURGO PEDIATRA. Considerazioni sull'approccio e valutazioni dalla Casistica Nazionale "TCG 91".
1996
Germ Cell Tumors (GCT) are rare in childhood, accounting for 2-4% of all solid neoplasms. Teratoma is the most frequent histological type (50%) of GCT and the most important neonatal tumors.. Authors analyze the results of the first Italian Multicentric Cooperative Study on GCTs in childhood (TCG 91). The role of surgical radical excision of the mass with thw coccyx in sacrococcygeal forms is streassed.
EXTRAGONADAL GERM CELL TUMORS: Results of AIEOP TCG 91/98 Protocols
2002
The aim of the Study: To analyze the outcome of patirnts with extragonadal (eg) GCT teated with TCG 91/98 Protocols. 45 pts were enrolled: 34 were females, 11 males; median age 17 months (range: 1-137 months)
THE ROLE OF SURGERY (s) IN THE TREATMENT OF GERM CELL TUMORS (GCT) IN CHILDHOOD. A Report from an Italian Multi-Istitutional Study (TCG-91)
1993
GCT account for about 3% of all solidi Neoplasms in children. Because of the confusion as to their classification, diagnostic apporoach and treatment, a multi-istitutional study was carried and a National Protocol for Diagnosis and treatment of CGT (TCG-91), approved by AIEOP, straded in January 1991.
MALIGNANT NON-SEMINOMATOUS GERM CELL TUMORS (MNSGCT) IN CHILDREN: Results of a Study of Italian Association Pediatric Oncology (AIEOP).
1995
The authors report the results of the Italian study on the treatment of non-seminomatous germ cell tumors in pediatric age and present the results of the diagnostic and therapeutic process in their experience
IL RUOLO DELLA CHIRURGIA NEL TRATTAMENTO DEI TUMORI GERMINALI IN ETA' PEDIATRICA: Analisi dello Studio Cooperativo "AIEOP TCG-'91.
1993
Authors analyze the preliminary results of the first multicentric cooperative study on Germ Celkl Tumors in childhood (TCG 91). The Authors discuss the role of primary surgical procedure on the treatment of benign forms and of resectable malignant tumors.
PEDIATRIC TESTICULAR GERM CELL TUMORS: the ASSOCIAZIONE ITALIANA ONCOLOGIA PEDIATRICA (AIEOP) study
2017
We describe the results of a therapeutic approach with a pediatric BEP regimen (bleomycin, etoposide, cisplatin) from the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) study on testicular germ cell tumors (TGCT).
Mature and immature teratoma: A report from the second Italian pediatric study
2015
Background. Teratomas demonstrate a benign clinical behavior, however they may recur with malignant components or as teratoma, and in a small group of patients prognosis could be fatal. After the ®rst Italian study, we collected cases of teratoma, alongside the protocol for malignant germ cell tumors. Procedure. Patients with teratoma were collected from 2004 to 2014. Teratomas were classi®ed according to the WHO classi®cations, as mature and immature. Patients with pathological aFP and/or bHCG, and those with a malignant germ cell component were not included. Results. The study enrolled 219 patients (150 mature, 69 immature teratomas) with a median age at diagnosis of 42 months. The primar…
