OBJECTIVES Brain metastases (BM) cause significant morbidity and mortality in patients with melanoma. We aimed to identify prognostic factors for overall survival (OS) in patients undergoing stereotactic radiosurgery (SRS) for BM from melanoma. METHODS We identified 135 patients treated with SRS at Emory University between 1998 and 2010 for BM from(More)
The aim of this study was to compare outcomes of postoperative whole brain radiation therapy (WBRT) to stereotactic radiosurgery (SRS) alone in patients with resected brain metastases (BM). We reviewed records of patients who underwent surgical resection of BM followed by WBRT or SRS alone between 2003 and 2013. Local control (LC) of the treated resected(More)
PURPOSE To investigate the relationship between the conformality index (CIn), heterogeneity index (HIn), and gradient index (GIn) and the development of toxicity in patients treated with Gamma Knife radiosurgery (GKRS) for intracranial meningiomas. METHODS AND MATERIALS Treatment records of patients treated from 1997 to 2009 with at least 6 months of(More)
The incidence of melanoma is rising in the United States, leading to an estimated 68,720 new diagnoses and 8,650 deaths annually. The natural history involves metastases to lymph nodes, lung, liver, brain, and often to other sites. Primary treatment for melanoma is surgical excision of the primary tumor and affected lymph nodes. The role of adjuvant or(More)
Conflicting clinical evidence regarding the possible association between androgen deprivation therapy (ADT) with heart failure in men with prostate cancer is reviewed, including 2 population-based registries showing such an association, and 1 showing no association. Studies of the effects of androgens on cardiomyocyte contractility at the molecular level,(More)
We retrospectively compared the outcomes and toxicities of melanoma brain metastases (MBM) patients treated with BRAF inhibitors (BRAFi) and stereotactic radiosurgery (SRS) with SRS alone. We identified 87 patients with 157 MBM treated with SRS alone from 2005 to 2013. Of these, 15 (17.2%) patients with 32 MBM (21.4%) received BRAFi therapy: three (20.0%)(More)
Centers in Japan and the United States are extending boron neutron capture therapy (BNCT) to the treatment of malignant melanoma (MM). Positron emission tomography (PET) has been used to image glioblastoma multiforme with18F-boronophenylalanine (18F-BPA) for the purpose of generating10B distribution maps. These distribution maps can be used to improve the(More)
Melanoma is an aggressive malignancy with a deplorable penchant for spreading to the brain. While focal therapies such as surgery and stereotactic radiosurgery can help provide local control, the majority of patients still develop intracranial progression. Novel therapeutic combinations to improve outcomes for melanoma brain metastases (MBM) are clearly(More)
Metastatic melanoma is difficult to treat, and often portends a grim prognosis. For patients with cerebral metastases, the prognosis is even more dire. Systemic immunotherapy and targeted agents are emerging as the mainstay of treatment for metastatic melanoma. Although immunotherapy has been shown to prolong relapse-free survival and long-term control of(More)
The incidence of melanoma is rising. The primary initial treatment for melanoma continues to be wide local excision of the primary tumor and affected lymph nodes. Exceptions to wide local excision include cases where surgical excision may be cosmetically disfiguring or associated with increased morbidity and mortality. The role of definitive or adjuvant(More)
