Abstract
Although the usefulness of high-dose chemotherapy with peripheral blood stem cell transplantation for advanced germ cell tumor is still under evaluation in phase III randomized controlled studies, this approach is currently used as one treatment option for relapsed or advanced male germ cell tumor. Clinical outcomes of high-dose chemotherapy for a single institute from Japan are presented herein. We administered 63 courses of high-dose ifosfamide, carboplatin and etoposide chemotherapy (1250 mg/m carboplatin; 1500 mg/m etoposide; 7.5 g/m ifosfamide) to 34 men with germ cell tumors. Of these, 27 patients underwent high-dose ifosfamide, carboplatin and etoposide as first-line therapy after 2-3 courses of conventional bleomycin, etoposide and cisplatin chemotherapy, and seven patients underwent high-dose ifosfamide, carboplatin and etoposide for relapsed germ cell tumor. Peripheral blood stem cells were harvested during previous chemotherapy and sufficient CD34 cells were harvested for transplantation. Although all patients experienced grade 4 hemotoxicity, leukocyte counts recovered to above 1000/mul within 8-11 days after peripheral blood stem cell transplantation. No treatment-related deaths occurred. After a mean follow-up of 45 months (range 12-118 months), 23 of 34 patients (67.6%) remained disease-free. High-dose ifosfamide, carboplatin and etoposide could be performed safely, and could offer an effective means of treating advanced or refractory germ cell tumors in men.

Abstract
BACKGROUND Primary intramedullary spinal cord germinoma is very rare. We encountered 2 patients with primary intramedullary spinal cord germinoma. We describe herein our comprehensive management system for CNS germinoma, including intramedullary spinal cord germinoma, along with a review of the literature. This is the first report to describe successful application of ICE chemotherapy for intramedullary germinoma. CASE DESCRIPTIONS A 16-year-old adolescent girl (case 1) experienced lumbago and subsequently noticed gait disturbance that aggravated gradually. On admission, paraparesis and urinary retention were noted. Magnetic resonance imaging demonstrated marked cord swelling between T9 and T12, with slight enhancement in the spinal cord. Astrocytic tumor was initially suspected, and partial removal was performed. However, pathologic examination identified germinoma. Successful treatment with ICE chemotherapy and radiotherapy was implemented, with no evidence of recurrence apparent at 48 months postoperatively. A 34-year-old woman (case 2) presented with paraparesis and sensory disturbance. Magnetic resonance imaging demonstrated cord swelling between T8 and T10, with slight Gd-DTPA enhancement. Because the lesion did not respond to steroid pulse therapy, spinal cord tumor was suspected and biopsy was performed. Pathologic examination verified primary germinoma of the spine. Successful treatment with ICE chemotherapy and radiotherapy was implemented with no exacerbation of neurologic deficits. No evidence of recurrence was apparent at 36 months postoperatively. CONCLUSION Correct diagnosis of very rare primary intramedullary spinal cord germinoma is important, because these patients can be treated successfully using chemo- and radiotherapy without neurologic deterioration.

Abstract
OBJECTIVE Hyperglycosylated human chorionic gonadotropin (hCG-H) is a carbohydrate variant of hCG with double-sized oligosaccharide side chains. While hCG-H is produced exclusively by stem cytotrophoblast cells in gestational choriocarcinoma, by pregnancy cytotrophoblast at implantation and by the cytotrophoblast produced in testicular malignancies, regular hCG is produced only by differentiated syncytiotrophoblast cells. STUDY DESIGN hCG-H was measured using the Nichols Advantage hCG-H assay (Nichols Institute Diagnostics, San Clemente, California). RESULTS hCG-H has a function separate from regular hCG. hCG-H, but not regular hCG, acts in vivo and in vitro to promote invasion, whether invasion through membranes or tumor formation. Invasion or tumorigenesis is completely blocked by administration of specific antibody to hCG-H. The same hCG-H-modulated invasion mechanisms are observed in early pregnancy, gestational choriocarcinoma and testicular cancers. CONCLUSION hCG-H is a cytokinelike molecule, produced by cells different from those that make regular hCG and having a completely separate function. It appears to be the modulator of invasion as in implantation of pregnancy, gestational choriocarcinoma and testicular cancer malignancy.

Abstract
A 29-year-old man presented with diplopia, dysarthria, anisocoria, oculomotor nerve paralysis, abducens nerve paralysis, right facial palsy, and spastic hemiparetic gait. Magnetic resonance imaging (MRI) showed a homogenously enhanced mass in the midbrain. MRI-guided stereotactic biopsy was performed, and the histologic diagnosis was pure germinoma. The tumor disappeared after chemotherapy and radiotherapy. Germinoma should be included in the differential diagnosis of midbrain lesions in young adults. MRI-guided stereotactic biopsy provided a helpful diagnostic clue in a patient with a midbrain lesion.

Abstract
OBJECTIVE Evaluation of results of the neurofiberscopic biopsy of tumors of the pineal region and posterior third ventricle. METHODS From 2001 to 2004, 23 patients (mean age, 30.6 yr) with tumors located in the pineal region or posterior third ventricle underwent neurofiberscopic biopsy with simultaneous third ventriculostomy. The procedure was indicated for verification of the histological diagnosis of the neoplasm, which was planned to be treated by radiotherapy and/or chemotherapy without open surgery (eight patients), establishment of the pathological diagnosis for further choice of the most appropriate treatment strategy (11 patients), differentiation of the recurrent neoplasm and radiation necrosis (two patients), and decompression of the large tumor-associated cyst (two patients). In six previously shunted patients, substitution of the ventriculoperitoneal shunt on the third ventricle stoma was performed. RESULTS There was no postoperative mortality or permanent morbidity. In all cases, the obtained tissue sample was sufficient for pathological diagnosis. Transient postoperative complications included fever (15 patients), nausea and vomiting (three patients), and diplopia (one patient). On the long-term follow-up, delayed third ventricular stoma failure caused by tumor regrowth and scar formation was found in one patient, and dissemination of the malignant glioma through the subarachnoid space was found in another patient. CONCLUSION Neurofiberscopic biopsy represents a useful method for sampling of tumors of the pineal region and posterior third ventricle, which can be effectively used in both previously shunted and shunt-free patients.

Abstract
PURPOSE To investigate prognostic factors for pediatric extragonadal malignant germ cell tumors (PEMGCT). MATERIALS AND METHODS Between 1990 and 1996, patients with stage I through IV PEMGCT were eligible for a trial of cisplatin dose intensity. We retrospectively investigated prognostic factors for PEMGCT, including age, stage, primary site, treatment, and elevated alfa fetoprotein by univariate and multivariate analysis. RESULTS The 165 patients had a median age of 1.9 years (range, 3 days to 18.5 years); 109 were female; and 99 had alfa fetoprotein > or = 10,000. There were 30 stage I/II, 61 stage III, and 74 stage IV tumors; primary sites included 88 sacrococcygeal, 39 thoracic, and 38 others. The 5-year overall survival (OS) and event-free survival (EFS) rates with standard deviations were 83.4% +/- 3.7% and 79.0% +/- 4.1%, respectively. Univariate analysis identified age > or = 12 years as a highly significant prognostic factor for EFS (5-year EFS, 48.9% +/- 15.6% v 84.1% +/- 3.9%; P < .0001) and for OS (5-year OS, 53.7% +/- 14.9% v 88.5% +/- 3.4%; P < .0001), whereas treatment was of borderline significance (P = .0777). Multivariate Cox proportional hazards regression identified only age > or = 12 years as a significant prognostic factor for EFS (P = .0002). In multivariate Cox regression for OS, the combination of age and primary site was highly significant (P < .0001). Patients > or = 12 years of age with thoracic tumors had six times the risk of death compared with patients younger than 12 years with other primaries. CONCLUSION Age is the most predictive factor of EFS in PEMGCT. There is a significant interaction between age and primary site, suggesting that patients > or = 12 years of age with thoracic tumors are a biologically distinct group.

Abstract
OBJECTIVE To evaluate the impact of lymphadenectomy on the relapse and survival of malignant ovarian germ cell tumor (OGCT). METHODS The clinical data of 102 OGCT cases treated in Peking Union Medical College Hospital from June 1980 to June 2003 were analyzed retrospectively. All the data about lymphadenectomy during primary and secondary surgery were collected, and other factors related to prognosis were also collected at the same time. Chi-squared test was applied in the univariate analysis related to relapse of disease. Cox model was applied in multivariate analysis related to relapse and survival of disease. RESULTS Pelvic and paraaortic lymph node metastasis was not significantly related to prognosis in primary and secondary treated patients. Lymphadenectomy showed no significant impact on disease relapse and survival. In the primary treatment, International Federation of Gynecology and Obstetrics (FIGO) staging, chemotherapy regimen, residual tumor and lymphadenectomy were the significant factors related to the relapse. After being stratified for the chemotherapy regimen, lymphadenectomy was not significantly related to the relapse in bleomycin +etoposide +cisplatin or cisplatin +vincristine +bleomycin regimen group, and lymphadenectomy could prevent relapse in no chemotherapy or other chemotherapy regimen group. In relapsed patients, only residual tumor was significantly related to survival time after relapse. CONCLUSIONS Pelvic lymph node metastasis is not the significant risk factor related to prognosis. Lymphadenectomy may have a beneficial effect on survival, although such effect is not significant. Although lymphadenectomy provides important information for prognosis, they provide little benefit to those patients already requiring chemotherapy based on the original operative findings. Lymphadenectomy should be performed to primary or relapsed patients by an expert surgical team.

Abstract
BACKGROUND Studies of fertility in men treated for testicular cancer have mainly addressed serum follicle-stimulating hormone levels and sperm parameters. We assessed post-treatment paternity among long-term survivors of testicular cancer. METHODS Men (n = 1814) who had been treated for unilateral testicular cancer in Norway during 1980 through 1994 were invited to participate in a national multi-center follow-up survey in 1998 through 2002. The participants were allocated to five groups according to the treatment received after orchiectomy, including treatment at relapse (surveillance, retroperitoneal lymph node dissection, radiotherapy, low-dose chemotherapy [i.e., < or = 850 mg cisplatin], and high-dose chemotherapy [i.e., > 850 mg cisplatin]). Cox proportional hazards analysis was used to assess predictive factors for post-treatment paternity. Statistical tests were two-sided. RESULTS A total of 1433 men were assessable, of whom 827 were fathers at diagnosis. Post-treatment conception was attempted by 554 men, among whom the overall 15-year actuarial post-treatment paternity rate was 71% (95% confidence interval [CI] = 66% to 75%) without the use of cryopreserved semen. This rate ranged from 48% (95% CI = 30% to 69%) in the high-dose chemotherapy group to 92% (95% CI = 78% to 98%) in the surveillance group (P < .001). The median actuarial time from diagnosis to the birth of the first child after treatment was 6.6 years overall but varied according to treatment. Assisted reproductive technologies were used by 22% of the couples who attempted conception after treatment. Dry ejaculation, treatment group, pretreatment fatherhood, and marital status were statistically significant independent predictors for post-treatment fatherhood, with dry ejaculation as the most important negative factor. CONCLUSIONS Although the overall paternity rate after treatment for testicular cancer was high, the ability to conceive and the time to conception reflected the intensity of treatment. These data may help inform patients about their future ability to father biological children.

Abstract
OBJECTIVE GH replacement is widely used in the management of patients with adult-onset (AO)-GH deficiency (GHD). In most cases, AO-GHD arises as a result of pituitary/peripituitary tumours and/or their treatment, but the effect of GH replacement on recurrence/regrowth of these tumours is unknown. The aim of this study was to examine the effect of GH replacement in a group of patients with primary tumours of the parasellar region, many of which (e.g. craniopharyngioma, glioma or germ cell tumours) might be anticipated to have a higher recurrence rate than secretory and nonsecretory anterior pituitary tumours. PATIENTS AND DESIGN We report here our experience of prospective imaging in 50 consecutive patients (21 males; mean age 45.9 years) with nonanterior pituitary parasellar tumours treated with GH. All had severe GHD (peak serum GH 9 mU/l or less on dynamic testing) and were treated with an identical dose-titration regimen to maintain serum IGF-I concentrations between the median and upper end of the age-adjusted normal range. The primary diagnoses were: craniopharyngioma (28), germ cell tumour (8), arachnoid cyst (4), meningioma (4), glioma (4) and mensenchymal tumour (2). External pituitary irradiation had been given to 37 (74%) of patients. Measurements Surveillance imaging (magnetic resonance imaging (MRI) 70%, computed tomography (CT) 16%, both 14%) was performed at baseline (prior to GH), at 6--12 months, and then again yearly or as clinically indicated. Median follow-up was 36 months (range 7--129 months). All images were reviewed by the same radiologist. RESULTS Four patients had an apparent increase in tumour volume but in only one patient was it considered necessary to abandon GH replacement. In two of the four cases marginal increases in cystic parasellar tumours were not progressive; and in the fourth case apparent recurrence of a suprasellar germ cell tumour was shown to be acellular fibrous tissue only on biopsy. In all other cases either the appearances were unchanged or the amount of tissue was reduced during long-term follow-up on GH. CONCLUSIONS Overall, GH appears safe with respect to tumour recurrence over this time period in this patient group. Comparison with similar prospective series in patients not receiving GH replacement is desirable.

Abstract
Optimal management of intracranial germinomas remains controversial. Focal irradiation to the primary tumor followed by prophylactic craniospinal radiotherapy represents the traditional treatment resulting in excellent long-term survival but potential late effects. To decrease late effects related to extensive fields of radiotherapy, combined chemotherapy and irradiation has been tested with reduced volumes and doses of radiation therapy. We report our experience about four patients successfully treated by neoadjuvant chemotherapy with carboplatin and etoposide followed by radiotherapy delivering 26 to 36 Gy to the whole brain and 36 to 50 Gy to the initial tumor volume.

Abstract
BACKGROUND The current study assessed the contribution of spinal irradiation to the treatment outcome of patients with intracranial germinoma. METHODS Clinical data from 180 patients with intracranial germinoma, who were treated with radiotherapy and/or chemotherapy from 1980 to 2001, were collected from 6 institutions. The patients' median age was 16 years (range, 1-47 yrs), and the male-to-female ratio was 133:47. Pathologic verification was obtained in 88 patients. A solitary tumor was seen in 129 patients, and multifocal or disseminated tumors were detected in 51 patients. The median tumor size was 2.5 cm (range, 0.6-7.0 cm). Local field and/or whole brain irradiation was performed in 114 patients, and craniospinal irradiation was performed in 66 patients. Fifty-five patients were treated with chemotherapy. The median follow-up time was 89 months (range, 3-297 mos). RESULTS Eight-year overall and event-free survival rates were 91% and 89%, respectively. The 8-year recurrence rates at the primary site, intracranial space, and the spinal space were 1%, 6%, and 6%, respectively. Cox regression analysis showed that spinal irradiation (hazard ratio, 1.050; 95% confidence interval [CI], 0.355-3.170) did not contribute to a favorable event-free survival. CONCLUSIONS Spinal irradiation did not contribute to favorable event-free survival in patients with intracranial germinoma.

Abstract
Purpose Patients with clinical stage I nonseminomatous germ cell tumors (NSGCTs) have been managed with surveillance, chemotherapy, or retroperitoneal lymphadenectomy (RPLND) with similar survival outcomes. Cost factors influencing the choice of therapy were evaluated using computer-based decision analysis. Methods A detailed model was developed that integrates projected costs for more than 60 possible treatment outcomes. It incorporates primary, adjuvant, and salvage chemotherapy, primary and postchemotherapy RPLND, and both laparoscopic and open surgical approaches. Starting values and probabilities were derived from a comprehensive meta-analysis of the last 25 years of testes cancer literature. Hypothesis testing was performed using sensitivity analysis. Results The model predicts a cost premium for both primary chemotherapy (18.7%) and RPLND (51.7%) compared with surveillance. If laparoscopic RPLND was practiced, the cost premium for primary surgery (29.1%) approached that of chemotherapy (26.4%). Open RPLND was 1.25× as costly as laparoscopic RPLND, primarily because of longer hospitalization. The choice of open RPLND yielded a 6.9% cost premium for a surveillance program in this model. For such a program, primary chemotherapy became cost advantageous when the probability of recurrence during surveillance was more than 46%. Conclusion This model allows a variety of treatment cost hypotheses to be tested. Primary RPLND is never cost advantageous over surveillance or primary chemotherapy. Surgical costs can significantly increase the overall cost of a surveillance program. In stage I patients with high-risk tumor characteristics, primary chemotherapy may have a cost advantage over surveillance.

Abstract
Klinefelter syndrome occurs in approximately 1 in 1000 males. A 4-year-old boy presented with precocious puberty and an anterior mediastinal mass. Serum alpha-fetoprotein and human chorionic gonadotropin levels were mildly increased. Computed tomography revealed a germ cell tumor (GCT) of the mediastinum. Complete resection of the tumor was performed. Histologic analysis revealed an immature teratoma. Males with Klinefelter syndrome develop GCTs at a rate 50 times higher than unaffected males. This case report calls attention to the need to rule out Klinefelter syndrome in boys who present with precocious puberty and a mediastinal GCT.

Abstract
INTRODUCTION The increasing number of childhood cancer survivors has resulted in a growing interest in the late effects, which depend on type of treatment. Frequently, a brain tumour and its therapy in children are endocrinologically devastating. AIM OF STUDY The aim of study was to compare growth and pubertal development in children after brain tumour therapy treated or not treated with recombinant growth hormone (rGH). MATERIAL AND METHODS 18 children were included in this study. Group I - (12/18) not treated with rGH, after total resection of brain tumour: craniopharyngeoma (8/12), astrocytoma (2/12) ependymoma (1/12), germinoma (1/12). Mean time of remission was 5,0yrs (+/- 0,9). Group II - (6/12) treated with rGH, after subtotal resection of craniopharyngeoma (4/6), ependymoma (1/6), medulloblastoma (1/6) and cranial irradiation with mean total doses 46,5 Gy (+/- 5,65). Children were qualified for rGH replacement according to deceleration of growth and lower growth hormone secretion (< 10 ng/ml) in stimulating tests. Mean time of remission was 6,5 yrs (+/- 2,41). Growth, height in centimeters converted to standard deviation score--SDS, body mass index (BMI), pubertal status and hormonal tests, were also evaluated. RESULTS All patients were treated with surgery with no cranial irradiation in prepubertal age. 100% children of group I needed substitution because of secondary hypothyreosis, 83% due to secondary adrenal insufficiency and 53% of diabetes insipidus. Mean height after brain tumour surgical treatment in group I was - 1,24 SDS (+/- 0,85) and did not significantly change in the time of observation. Two girls needed hormonal substitution for hypogonadotropic hypogonadism. Mean BMI after total resection of brain tumour was 18,09 (+/- 4,20) and significantly increased to 23,73 (+/- 2,82). In group II - all children presented multihormonal pituitary insufficiency. Mean deviation score of height before rGH treatment was - 3,84 SDS (+/- 2,87) and after mean time of rGH therapy of 1,5 yrs (+/- 1,2) decreased to 2,6 (+/- 1,06). Mean BMI before treatment with rGH 18, 06 (+/- 4,4) increased to 22,41 (+ 0,74) in the time of observation and decreased to 18,5 (+/- 2,87) after 1,5 years (+/- 1,2) of rGH treatment. CONCLUSIONS 1. Children treated with surgery for brain tumour need substitution for secondary hypothyroidism, part of then need treatment for secondary adrenal and gonadal insufficiency and diabetes incipidus. 2. Children who were treated with surgery and/or cranial irradiation developed multihormonal pituitary insufficiency, growth failure and replacement rGh therapy was needed. 3. Total resection of brain tumour without chemo- and radiotherapy did not impair growth in first years after surgery.

Abstract
BACKGROUND Although the aim of chemosensitivity tests is to predict the efficacy of anticancer agents for individual patients, no generally accepted assay has been established. METHODS A chemosensitivity test was conducted for solid tumors with an organ culture system using collagen gel matrix (CGM). Seventy-five samples of transitional cell carcinoma (TCC), 20 of germ cell tumor (GCT) and 13 of renal cell carcinoma (RCC) were used for the chemosensitivity test, and 20 patients were treated with anticancer drugs on the basis of the test results. RESULTS Positive rates of anticancer drugs for the 75 TCC samples were 64.9% for carboplatin, 63.4% for cisplatin, 32.1% for etoposide, 19.7% for THP-adriamycin, 16.7% for vinblastine, and 12.3% for methotrexate, indicating that positive rates of the latter three agents consisting of an MVAC regimen were unexpectedly low. The GCT had higher positive rates than the other cancers while RCC had the lowest. In 20 eligible patients (seven patients with bladder tumors and 13 with GCT), the true positive and true negative rates were 42% (5/12) and 75% (6/8), respectively, and the sensitivity and specificity were 71% (5/7) and 46% (6/13), resulting in a 55% (11/20) accurate predictive value. CONCLUSION Although predictive accuracy was moderate when combination chemotherapy was used, information about chemosensitivity may have some beneficial effect on the treatment of patients with invasive bladder cancer or advanced GCT, because insensitive drugs detected by the test could be deleted or replaced with more sensitive ones.

Abstract
A 21-year-old man with a 5-month history of diplopia caused by isolated vertical ocular misalignment had normal laboratory studies, including brain magnetic resonance imaging (MRI). Eight months after the onset of diplopia, he reported dry mouth, polydipsia, polyuria, and absent sweating. Examination now disclosed light-near dissociation of the pupillary responses, convergence-retraction nystagmus, and upgaze palsy. MRI revealed enhancing suprasellar and pretectal masses presumed to be germinomas. Two years after brain irradiation and systemic chemotherapy, no lesions are apparent on MRI and hypothalamic dysfunction has partially resolved. In a young patient with isolated vertical diplopia and normal brain imaging, one should consider an early pretectal syndrome and inquire after manifestations of hypothalamic dysfunction.

Abstract
Testicular germ cell tumours (TGCT), including seminomas, embryonal carcinomas, teratomas and yolk sac tumours, have a common precursor, the carcinoma in situ (CIS) cell. Recent gene expression studies displaying close similarity of CIS cells to embryonic stem cells support the longstanding theory that CIS most likely originates in utero from fetal gonocytes. The clinical association between the testicular dysgenesis syndrome components (TGCT, cryptorchidism, genital malformations, some forms of decreased spermatogenesis) also implies a prenatal origin. Despite high cure rates of TGCT, efforts should be made to obtain diagnosis at the CIS stage, as intervention is possible before an invasive tumour develops, thus reducing the necessity for intensive therapy. CIS may be suspected in patients with an assumed extragonadal GCT or cryptorchidism, and in intersex patients and selected cases with infertility (presenting with atrophic testes and ultrasonic microlithiasis). Surgical testicular biopsy seems the only reliable diagnostic method. The management of choice of unilateral CIS is orchidectomy, or localised irradiation in bilateral cases. At least 5% of TGCT patients present with contralateral CIS; therefore, contralateral biopsy is recommended at the time of orchidectomy. Further research is warranted to identify causal factors explaining the increasing incidence of TGCT and to obtain a method of non-invasive CIS detection.

Abstract
The Late Effects Study of the Canadian Childhood Cancer Surveillance and Control Program was designed to assess psychosocial and physical health outcomes among survivors of childhood cancer compared to general population controls. The objectives of this paper are to describe the design and methodology of the multi-centre, retrospective cohort study, present clinical characteristics of the survivor population, and evaluate the representativeness of study controls. Response rates were 63% for surivors (n = 2,152) and 49% for controls (n = 2,432). Survivors with germ cell turmours and carcinomas were slightly under-represented among participants as were those who received more intense or multiple series of therapy. Study controls were similar to Census individuals based on marital and work status but did have a slightly higher level of education and income. Otherwise, no large or systematic differences were found. Thus, these long-term survivors and population controls can be validly studied to evaluate whether and to what extent survivors experience an excess of psychosocial or physical health problems compared to similarly aged Canadians who have never had cancer.
