Abstract
The presence of brain metastases (BMs) from germ cell tumor (GCT) remains a rare situation. BMs predominantly occur among patients with testis primary tumor site, and are almost exclusively associated with non-seminomatous (NS) histologies. Two situations must be distinguished, which differ in terms of clinical presentation, overall prognostic and management. At diagnosis, BMs are almost systematically associated with extra-cerebral metastases and the cornerstone of treatment is chemotherapy, while the role of local treatment remains controversial. In the metachronous setting, BMs more frequently constitute an isolated site of relapse, the outcome is poorer, and the role of local treatment is more consensual. However, all these data widely come from old reports, with outdated radiation techniques. The recent advances in radiation oncology, especially the rising use of stereotactic radiotherapy, could lead to the reconsideration of ancient dogmas regarding the "radiosensitivity" of (NS)GCT and the role of radiotherapy among patients with BMs.

Abstract
Melanoma brain metastasis that develops as the isolated first visceral site challenges the current paradigm of tumor progression in which brain metastasis is regarded as the final stage. Here we test the hypothesis that melanoma patients who develop brain metastasis as the isolated first visceral site have distinct clinicopathological features at the time of primary melanoma diagnosis. Cutaneous melanoma patients enrolled in 2 prospectively collected databases were studied (Cohort 1: 1972-1982, Cohort 2: 2002-2009). Patients who developed brain metastasis as isolated first visceral site were compared with (1) all other patients, (2) patients who developed visceral metastasis: extracranial only or extracranial and brain, and (3) patients who progressed to other isolated visceral sites first. Two hundred seven of 2280 (9.1%) patients developed brain metastasis (median follow-up, 5.2 y). Seventy-four of 207 (35.7%) brain metastasis patients progressed to brain metastasis as the isolated first visceral site. These patients presented with primaries that were thinner and had no mitosis compared with all other visceral metastasis patients (Fisher's combined P = .02, .05, respectively), and there was a significant difference in American Joint Committee on Cancer stage distribution at initial melanoma diagnosis (combined P = .02). Post-visceral metastasis survival, however, was shorter in patients with brain metastasis as isolated first visceral site than in patients with visceral metastasis: extracranial and brain (combined P = .03). Brain metastasis as isolated first visceral site is a distinct clinicopathological entity. Studies are needed to better understand the biological factors driving this phenotype at the time of primary melanoma diagnosis and to determine its clinical implications.

Abstract
Brain metastases occur in approximately 10% of patients with advanced metastatic germ cell tumors. Patients with nonseminomatous histology, lung metastases, and high β-human chorionic gonadotropin levels are at higher risk for synchronous brain metastases at first diagnosis and for relapsing with brain metastases after successful cisplatin-based chemotherapy. Patients with brain metastases should undergo multimodal treatment strategies, including cisplatin-based combination chemotherapy plus radiotherapy or surgery. However, the optimal combination and sequence of these strategies remain unclear and may differ between subgroups. But in all cases, chemotherapy must be part of treatment, even in patients with isolated cerebral relapse without systemic disease.

Abstract
Brain metastasis occurs rarely in patients with testicular cancer in the modern era where cisplatin-based chemotherapy regimens are used. The occurrence of brain metastasis can be synchronous or metachronous (with or without concurrent systemic disease). Long-term survival can be achieved in some patients. The vast majority of testicular cancer cases with brain metastasis reported in the literature involve nonseminomatous germ cell tumor and this subtype will be the focus of this review. This article reviews the literature of the diagnosis and management of brain metastasis from nonseminomatous germ cell tumor of the testis.

Abstract
PURPOSE Germ cell tumors are uniquely chemosensitive and curable, even with advanced metastatic disease. Central nervous system recurrence can terminate a complete remission in other chemosensitive tumors, such as small cell lung cancer, because of the blood-brain barrier (BBB). We propose to document that the BBB is also relevant in germ cell tumors despite their dramatic chemosensitivity. METHODS AND MATERIALS We present five cases illustrating the concept of the BBB in patients with metastatic testicular cancer treated with chemotherapy. RESULTS In our large series of patients with metastatic testicular cancer treated with chemotherapy, we identified 5 unique patients. These patients were rendered free of disease only to experience relapse in the brain alone. This included 1 patient who initially had good-risk metastatic disease by means of the International Germ Cell Collaborative Group staging system at the onset of chemotherapy. CONCLUSIONS The BBB is relevant in patients with metastatic testicular cancer.

Abstract
Brain metastases from non-seminomatous germ cell tumors (NSGCTs) are rare and mainly occur in young men whose clinical condition is unimpaired. The records of 15 patients with brain metastasis from non-seminomatous germ cell tumors of the testis, who had been surgically treated between 1984 and 1998, were retrospectively reviewed. All of the patients had undergone surgery plus whole-brain radiotherapy (WBRT), and chemotherapy based on cisplatin. On admission they had a median age of 33 years and their mean Karnofsky performance scale (KPS) score was >70. Mean survival was 37.7 months. Eight patients had a survival period longer than 5 years. Five patients belonged to radiation therapy oncology group (RTOG) class I; all of them survived. There was a significant difference in survival time between patients in whom the brain metastasis was present at diagnosis (six survivors at 5 years; mean survival 53 months) and patients in whom the brain metastasis occurred during or after chemotherapy (two survivors at 5 years; mean survival 24 months) (P = 0.04). The presence of a trophoblastic component at histopathological analysis of the metastasis negatively influenced survival at univariate analysis. Multiple brain metastasis proved to be a significant risk factor at both univariate and multivariate analysis, while a metastatic residue with a diameter less than 2 cm after surgery did not negatively affect survival in our series. Prognosis is worst in patients with multiple brain metastases, in whom brain involvement occurred during or after cisplatin-based chemotherapy. Considering that these metastases are often both radiosensitive and chemosensitive, and mainly affect young men that are in very good clinical condition, we advocate aggressive treatment with surgery plus adjuvant radiotherapy and chemotherapy. This is mandatory in patients with large metastases (diameter >3 cm).

Abstract
To our knowledge, there are no published reports on the effectiveness of radiosurgery in the management of brain metastases from testicular nonseminomatous germ cell tumor. The authors evaluate the results of gamma knife (GK) treatment in three patients with these unusual intracranial lesions. Between April 1995 and July 2001, three patients with brain metastasis from testicular nonseminomatous germ cell tumor underwent adjuvant radiosurgery at our department. The primary tumor had been surgically removed in all cases. At diagnosis, one patient was stage IB and two were stage III poor risk. Chemotherapy and whole brain radiotherapy were administered before radiosurgery in all cases. Pre-GK radiotherapy was administered with a daily fraction dosage of 1.8-2.0 Gy. The indications for radiosurgery were tumor volume <20 cm3, microsurgery too risky, refusal of surgery. All the lesions were located in eloquent brain areas. Post-GK high-dose chemotherapy with autologous peripheral-blood stem-cell rescue was administered in two cases due to systemic recurrence of the disease. All patients are still alive with a median and mean follow-up period after radiosurgery of 63 and 68.3 mo, respectively. They had no neurological deficits at the latest examination. Neuroradiological follow-up invariably showed tumor growth control (complete response in two cases and partial response in one) with typically delayed post-radiosurgical imaging changes (transient in two cases and long-lasting in one). In conclusion, GK seems to be highly effective and safe in brain metastases from testicular nonseminomatous germ cell tumor. In cases with diffuse metastatic brain involvement, the whole brain radiotherapy preceding radiosurgery should be delivered with 1.8 Gy daily fraction to prevent the risk of long-lasting post-radiosurgical imaging changes.

Abstract
We report an unusual case of testicular cancer metastasized solely in the brain and spleen without retroperitoneal disease or other widespread metastasis. The patient initially presented with seizures and underwent craniotomy for presumed primary brain tumor, with a delayed diagnosis of testicular cancer as the true primary. This pattern of spread is highly unusual, and, to our knowledge, we report the first case of splenectomy performed for involvement by testicular cancer. At last follow-up, the patient was doing well, with no evidence of disease after 2 years.
