e13027 Background: Intracranial germ cell tumors (GCTs) represent up to 11 percent of pediatric central nervous system (CNS) tumors in Asia. We compared the efficacy of radiotherapy alone (RT) with platinum-based chemotherapy (CT) in combination with dose-attenuated RT. Methods: We identified 61 patients treated at National Cancer Centre Singapore from 1995 to 2011. Patient’s demographics, histopathologic characteristics and survival data were collected. Median follow up was 39 months. Results: Forty-eight (79%) patients were male; mean age at diagnosis was 17 years. Most (87%) patients had pineal or suprasellar tumors. The distribution of pure germinomas, non-germinomatous tumors and mixed tumors was 54 (89%), 5 (8%) and 2 (3%) patients, respectively. Twenty patients had RT alone, 2 had CT alone, and 31 received a combination of CT and attenuated RT. There was no difference in overall survival (OS) between unifocal or multifocal disease (p = 0.81). Amongst the germinomas, there was no difference in OS between patients given RT alone and CT combined with attenuated RT (median OS not reached vs 145 months, respectively, p = 0.668). Conclusions: Treatment with CT followed by dose attenuated RT is an alternative to conventional craniospinal RT and did not compromise survival in patients with germinomas. This may represent a therapeutic modality with a more favorable long term toxicity profile in these patients who have excellent long term outcomes.

10063 Background: Intracranial germ cell tumors (iGCT) constitute 1% of all malignant neoplasms in children. The aim of this study is to evaluate the demographic characteristics, therapy, and long term outcome of children with iGCT in a single institution. Methods: 16 children (9 female, 7 male) with a median age of 11 years (10 months-18 yrs) treated for iGCT between 1990 and 2008 were evaluated retrospectively. They were treated according to our institutional protocol. Patients > 13 years old with germinomas recieved radiotherapy alone (2520 cGy craniospinal/1980 cGy local boost), patients <13 yrs old recieved 2 courses of etoposide, cisplatinum followed with cranial radiotherapy. Nongerminoma patients recieved 3 courses of bleomycine, etoposide, cisplatinum followed by 3600 cGy craniospinal / 1980 cGy local boost RT. Results: Presenting clinical features were diabetes insipidus (7), raised intracranial pressure (12), visual changes-oculomotor palsies (6), hypopituitarism (4). 8 had germinomas and 8 nongeminomatous GCT. Ten were suprasellar and 6 pineal. AFP and BHCG were evaluated at diagnosis and during therapy both in serum and CSF. Three had seeding in the spinal axis in MRI. One had widespead systemic metastasis. Three had a total resection, 12 had a biopsy, 1 was clinically/radiologically diagnosed, 5 had a shunt. Two nongerminamatous iGCT patients died: 1 of widespread disease in the intensive care unit at diagnosis, the other with progressive disease 18 months after diagnosis. Fourteen patients are alive at a median follow-up of 12 years (1–17 years) from diagnosis. One that had motor and mental retardation before diagnosis needs special care. All others have a moderate/good quality of life. One is married and has a child. Six are at school (2 in university). Five are employed. The patients are also followed up in the endocrinology clinic. One is recieving growth hormone. Conclusions: Cisplatin based chemotherapy and radiotherapy is successful and well tolerated in children with iGCT. The possibility of an early clinical diagnosis based on MRI and tumor markers and the use of modern neurosurgical techniques increases the chance of cure, gives a chance to reduce acute morbidity and further decrease late effects.

PURPOSE In men with metastatic germ cell tumors (GCTs), risk-directed treatment is determined, in part, by a distinction between seminoma and nonseminomatous GCT (NSGCT). The importance of NSGCT cell type is uncertain. We evaluated the long-term impact of teratoma on survival in patients with NSGCT. METHODS Prechemotherapy, primary tumors from patients who received platinum-based chemotherapy were studied, and the histology was confirmed by a genitourinary pathologist. The cumulative incidence of disease-related death (CIDD) was the primary end point, and a competing-risk analysis was performed. RESULTS Tumors were available from 232 patients, including 193 with NSGCT. An element of teratoma was present in 82 NSGCT primary tumors (42%). With a median follow-up of 17 years (range, 0.3 to 35 years), 58 patients with NSGCT died, 47 as a result of GCT and 11 as a result of other causes. Most GCT deaths occurred within the first 5 years and were associated with pretreatment risk status ( P < .001). Death as a result of other causes rose steadily after 15 years and was not associated with risk status ( P = .66). A higher CIDD was observed in patients who had NSGCT with teratoma than those with NSGCT without teratoma and seminoma (5-year CIDD rate, 27.4%, 17.4%, and 10.3%, respectively; P = .03). A higher CIDD was observed in patients who had NSGCT with mature teratoma compared with those with either NSGCT with immature teratoma or NSGCT without teratoma (5-year CIDD rate, 38.1%, 19.9%, and 17.4%, respectively; P = .01). CONCLUSION The presence of teratoma, particularly mature teratoma, in an NSGCT primary tumor is associated with a higher CIDD, consistent with the hypothesis that differentiation is associated with adverse outcomes. Death as a result of non-GCT causes is not associated with risk status and must be separated from GCT death when evaluating long-term survival.

e22526 Background: Survival rates for childhood cancer continue to rise, and there are now greater than 420,000 survivors in the United States. However, high cure rates come at the cost of short and long-term treatment-related toxicities. Endocrine disorders are among the most common late effects and are associated with poor health outcomes and lower quality of life. Survivors of pediatric intracranial germ cell tumors (iGCTs) are at high risk for endocrine disorders, particularly for growth hormone deficiency (GHD), due to their exposures to cranial radiation, chemotherapy, and brain surgery. To date, no long-term follow-up studies have explored the late effects experienced by survivors of iGCTs. Methods: Study participants were enrolled in the Germ Cell Tumor Epidemiology Study, which is a case-parent triad study conducted using the resources of the Children’s Oncology Group’s Childhood Cancer Research Network. Eligibility criteria included diagnosis with a germ cell tumor in any location at age 0-19 years in the years 2008-2015. The study population included 233 cases with a diagnosis of iGCT. We are currently following the cohort to evaluate outcomes and late effects of treatment, including medical record review to extract data on treatment characteristics and hormone deficiencies. This interim analysis includes chart review for 57 iGCT cases. Results: Of the 57 cases reviewed, there was a male predominance (73.7%) with the highest prevalence in non-Hispanic whites (80.4%). Cases of iGCTs can be subdivided into two main histologic subtypes, germinomas (36 cases) and non-germinomatous GCTs (NGGCT, 21 cases). The median age at diagnosis was 14.6 years for the germinomas and 10.5 years for NGGCTs. Data on growth hormone deficiency (GHD) was available for 42 of the 57 cases with a median follow-up of 7.4 years. Twenty-eight of the 42 cases (66.7%) had GHD; 19 in the germinoma group and 9 in the NGGCT group (p = 0.47). 17 of those with GHD were males (p = 0.10). There was no significant difference in prevalence of GHD by age of tumor diagnosis (p = 0.20). Conclusions: Survivors of iGCTs are at high risk for growth hormone deficiency. Identifying specific risk factors for developing GHD amongst these survivors can enhance the current guidelines for screening and management.

PURPOSE: To identify therapy-related or patient-related characteristics that predict response and long-term survival after failure of high-dose chemotherapy (HDCT) for germ cell tumors (GCT). PATIENTS AND METHODS: Between 1986 and 1997, 101 GCT patients relapsed after high-dose carboplatin and etoposide (VP-16) at Indiana University (Indianapolis, IN). Median time to relapse was 10 months (range, 1 to 17 months). HDCT was the first salvage treatment in 29 patients and second or later salvage treatment in 72 patients. RESULTS: Fifty-four of 101 patients received post-HDCT treatment. Of these, 47 received chemotherapy, alone (n = 35) or in combination with surgery (n = 12). Seven patients underwent surgery alone. There were only 12 objective responses (three complete and nine partial responses) for 66 chemotherapy regimens given to 47 patients, for an overall response rate of 18.2%. Fifteen patients received platinum-based chemotherapy, with only one objective response. Chemotherapy was discontinued in 17% of cases because of toxicity. A longer interval between HDCT and post-HDCT treatment was the only variable that was associated with response. Five patients (4.9%) are disease-free at 30, 53, 57, 85, and 93 months after relapse. Of these, three responded to oral VP-16 and underwent resection of residual mediastinal, retroperitoneal, and inguinal cancer, respectively. One had resection of residual mediastinal yolk sac tumor, followed by oral VP-16. One relapsed with teratoma and received thoracoabdominal resection without chemotherapy. CONCLUSION: Patients who experience disease progression after HDCT often receive further chemotherapy and/or surgery. Chemotherapy resulted in a response rate of less than 20%, with only three complete responses. All of the long-term survivors (4.9%) had surgery as a component of their post-HDCT regimen.

OBJECTIVEThe current study aimed to evaluate the treatment outcomes and toxicities of patients with intracranial germ cell tumors (GCTs).METHODSThis study retrospectively included 110 consecutive patients (70 patients in the germinomatous group and 40 patients in the nongerminomatous GCT [NGGCT] groups) receiving surgery, platinum-based chemotherapy, and radiotherapy for newly diagnosed primary intracranial GCTs. In the authors’ protocol, patients with GCTs were further divided into the following four groups: the germinomatous group and the NGGCT groups (mature teratoma, intermediate prognosis, or poor prognosis).RESULTSThe median overall survival (OS) and progression-free survival (PFS) rates of the patients in the germinomatous group were significantly higher than those in the NGGCT group (p < 0.001). The 5-, 10-, and 20-year OS rates in the germinomatous group were 97.1%, 95.7%, and 93.2%, respectively, with a median follow-up of 11.0 years. On the contrary, the 5-, 10-, and 20-year OS rates in the NGGCT group were 67.3%, 63.4%, and 55.4%, respectively. The 5-, 10-, and 20-year PFS rates were 91.4%, 86.6%, and 86.6%, respectively, in the germinomatous group, whereas those of the NGGCT group were approximately 67.4%, 60.2%, and 53.5%, respectively. Based on the four types of classification in our study, the 5-, 10-, and 20-year OS rates in the NGGCT intermediate prognosis group were 78.9%, 71.8%, and 53.8%, respectively. On the contrary, the 3- and 5-year OS rates in the NGGCT poor prognosis group were 42.9% and 34.3%, respectively. Moreover, toxicities with the treatment of intracranial GCTs were found to be tolerable in the present study population. The multivariate survival models for OS in the NGGCT intermediate prognosis and poor prognosis groups demonstrated that only the alpha-fetoprotein status was significantly associated with worsened OS (HR 3.88, 95% CI 1.29–11.66; p = 0.02).CONCLUSIONSThe authors found that platinum-based chemotherapy and radiotherapy result in favorable survival outcomes in patients with germinomatous GCTs. Clinical outcomes were still unfavorable in the NGGCT intermediate prognosis and poor prognosis groups; therefore, a new protocol that increases the survival rate of patients belonging in both groups should be considered.
