Brainstem metastases offer a unique challenge in cancer treatment, yet stereotactic radiosurgery (SRS) has proven to be an effective modality in treating these tumors. This report discusses the clinical outcomes of patients with brainstem metastases treated at Indiana University with Gamma Knife (GK) radiosurgery from 2008 to 2016. 19 brainstem metastases from 14 patients who had follow-up brain imaging were identified. Median tumor volume was 0.04 cc (range: 0.01-2.0 cc). Median prescribed dose was 17...

Development of immunotherapy has dramatically changed poor prognosis of metastatic malignant melanoma (MM). Inhibition of immune checkpoints represents a new effective treatment. Monoclonal antibodies against CTLA-4 ipilimumab and against PD-1 (programme death 1) nivolumab and pembrolizumab prolong progression free survival and overall survival (OS) in patients with advanced metastatic MM. Both achieved significant improvement in relapse-free survival and OS also in adjuvant setting. It looks like the efficacy of the combined immunotherapy of ipilimumab with anti-PD-1 antibodies is superior to the monotherapy, but combined therapy is accompanied by higher toxicity...

BACKGROUND: For patients with a brain metastasis (BM), systemic therapy is usually administered after the completion of radiotherapy, especially in cases of multiple BMs. However, the role of systemic therapy in patients with a limited number of BMs is not clear. Therefore, we conducted a retrospective study to explore this question. METHODS: Consecutive patients with a pathologically confirmed malignancy and 1-3 intracranial lesions that had been documented within the last decade were selected from the databases of three hospitals in China...

Brain metastasis is an increasing problem in non-small cell lung cancer (NSCLC) patients. Tyrosine kinase inhibitors (TKIs), including gefitinib, erlotinib, and icotinib, are reported to be effective in patients with brain metastases. However, direct comparative studies of the pharmacokinetics and efficacy of these three drugs in treating brain metastases are lacking. In the present investigation, we found that gefitinib penetrated the blood-tumor barrier and was distributed to brain metastases more effectively than erlotinib or icotinib in a nude mouse model...

Background: Management of brain metastases typically includes radiotherapy (RT) with conventional fractionation and/or stereotactic radiosurgery (SRS). However, optimal indications and practice patterns for SRS remain unclear. We sought to evaluate national practice patterns for patients with metastatic disease receiving brain RT. Methods: We queried the National Cancer Data Base (NCDB) for patients diagnosed with metastatic non-small cell lung cancer, breast cancer, colorectal cancer, or melanoma from 2004 to 2014 who received upfront brain RT...

An atypical type A thymoma is a newly added entity to the last World Health Organization (WHO) histological classification [2015] of uncertain prognosis. The conventional type A and AB thymomas are usually locally aggressive neoplasms that rarely metastasize with distant metastases to the central nervous system (CNS) occurring extremely exceptionally. We present a history of a woman with a mediastinal tumor originally considered to be a Masaoka-Koga stage II "mixed thymoma with well-differentiated thymic carcinoma component" according to the historic Müller-Hermelink nomenclature...

Background: Esophageal cancer is the eighth most common cancer worldwide. The prognosis of esophageal cancer patients is dismal, especially those with distant organ metastasis. However, there are few studies describing the patterns of distant metastasis in esophageal cancer systematically. Methods: We gathered the data from Surveillance Epidemiology and End Results (SEER) database between 2010 and 2013. Categorical variables were analyzed by the Pearson Chi square test, and continuous variables were analyzed by the two-sample t test...

OBJECTIVE Myxopapillary ependymoma is a benign WHO Grade I tumor most commonly located in the conus-cauda equina region of the spine. Although this tumor is defined by an overall excellent survival, dissemination throughout the whole neuraxis occurs frequently. The current study evaluated the clinical characteristics and significance of myxopapillary ependymoma metastases. METHODS Patients who underwent surgery from 2005 to 2015 for treatment of spinal myxopapillary ependymoma were included in the study. Charts were reviewed for primary tumor symptoms and initial treatment, local recurrence, response to salvage therapy, and presence and behavior of distant metastases...

Patients treated with stereotactic radiosurgery (SRS) for brain metastases (BM) are at increased risk of distant brain failure (DBF). Two nomograms have been recently published to predict individualized risk of DBF after SRS. The goal of this study was to assess the external validity of these nomograms in an independent patient cohort. The records of consecutive patients with BM treated with SRS at Levine Cancer Institute and Emory University between 2005 and 2013 were reviewed. Three validation cohorts were generated based on the specific nomogram or recursive partitioning analysis (RPA) entry criteria: Wake Forest nomogram (n = 281), Canadian nomogram (n = 282), and Canadian RPA (n = 303) validation cohorts...

Purpose: The optimal treatment strategy following local recurrence after stereotactic radiosurgery (SRS) remains unclear. While upfront SRS has been extensively studied, few reports focus on outcomes after retreatment. Here, we report the results following a second course of SRS for local recurrence of brain metastases previously treated with SRS. Methods: Using institutional database, patients who received salvage SRS (SRS2) following in-field failure of initial SRS (SRS1) for brain metastases were identified...

Alveolar soft part sarcoma (ASPS) is a rare malignant tumor that generally occurs in adolescents and young adults. It progresses slowly, but lung and brain metastases often occur in the early phase of the clinical course, and chemotherapy has been reported as not being effective for ASPS. Pazopanib is a multitargeted tyrosine kinase inhibitor that has been clinically available from November 2012 in Japan. This is a case report of a patient presented with multiple lung metastases and unresectable primary abdominal ASPS...

Brain metastases are common and are usually detected by magnetic resonance imaging (MRI). Diffusion tensor imaging (DTI) is a derivative MRI technique which can detect disruption of white matter tracts in the brain. We have matched preoperative DTI with image-guided sampling of the brain-tumor interface in 26 patients during resection of a brain metastasis and assessed mean diffusivity (MD) and fractional anisotropy (FA). The tissue samples were analysed for vascularity, inflammatory cell infiltration, growth pattern, and tumor expression of proteins associated with growth or local invasion such as Ki67, S100A4, and MMP2, 9, and 13...

BACKGROUND: The retina is an uncommon site for metastases, in particular from solid tumors. Some authors have reported a recent increase in the incidence of metastases in infrequent sites, such as brain or bone, probably due to the expanded treatment options and the resulting improved survival. Choroidal metastasis is the most common type of intraocular malignancy. The most common primary sites associated with choroidal metastasis are breast cancer in women and lung cancer in men. Treatment options are limited, but they must be discussed and adapted to the patient profile...

Brain metastases from NSCLC are associated with a poor prognosis, and local radiotherapy is the most effective therapeutic strategy. The oncofetal protein IMP3 has been studied extensively, and evidence suggests that its expression is related to shorter overall survival and a more aggressive phenotype in solid malignancies. Here, the prognostic role of IMP3 was investigated in a cohort of patients with NSCLC brain metastases in correlation with survival and tumor histotype. A series of 42 NSCLC brain metastases samples was analyzed by tissue microarray and immunohistochemical staining for IMP3...

BACKGROUND: Prophylactic cranial irradiation (PCI) reduces the risk of overt brain metastases in patients with small-cell lung cancer (SCLC) and is currently recommended in guidelines for both limited and extensive disease. Given the concerns about the greater frequency of neurologic side effects in elderly patients, we studied the association among age, PCI usage, and survival for SCLC patients in the Netherlands. PATIENTS AND METHODS: Data from the Netherlands Cancer Registry for patients diagnosed with SCLC from 2009 to 2013 were queried...

Purpose: Stereotactic radiosurgery (SRS) in combination with immunotherapy (IMT) or targeted therapy is increasingly being used in the setting of melanoma brain metastases (MBMs). The synergistic properties of combination therapy are not well understood. We compared the distant intracranial failure rates of intact MBMs treated with SRS, SRS + IMT, and SRS + targeted therapy. Methods and materials: Combination therapy was defined as delivery of SRS within 3 months of IMT (anti-CTLA-4 /anti-PD-1 therapy) or targeted therapy (BRAF/MEK inhibitors)...
