Expert review of anticancer therapy

Brain metastases are a common site of metastasis from malignant melanoma, and are associated with a poor prognosis. Diagnosis of brain metastasis may also have significant implications for quality of life, and management can be difficult due to rapid progression of disease and resistance to conventional therapies. In this article, we will review the published evidence for treatment modalities for melanoma-induced brain metastases and outline future directions for research. ⋯ External-beam radiation alone appears effective in palliating symptoms. Chemotherapy alone is relatively ineffective, though combined chemotherapy with external-beam radiation is being investigated. Future directions include combined-modality therapy, the incorporation of novel agents, and careful consideration of the structure of clinical trials for this disease.

ReviewImmunotherapy against angiogenesis-associated targets: evidence and implications for the treatment of malignant glioma.
Angiogenesis, the growth of new blood vessels from previously existing vasculature, is a requirement for tumor growth and metastasis. The first US FDA-approved drugs targeting angiogenesis have shown potential in the treatment of malignant gliomas. Immunotherapy as a treatment modality lends itself well to specifically targeting angiogenesis in tumors and may represent a powerful tool in the treatment of malignant gliomas. This review focuses on developments in immunotherapy targeting angiogenesis and tumor-vascular-specific endothelial cells using a variety of immunotherapeutic strategies including monoclonal antibodies and conjugated immunotoxins, as well as cellular, peptide, DNA and dendritic cell vaccines.

ReviewProgress and challenges in the adjuvant treatment of stage II and III colon cancers.
Whereas the benefit of adjuvant 5-fluorouracil and leucovorin have been well established in resected stage III colon cancer, a significant benefit for patients with stage II disease has been more difficult to demonstrate. More recently, oxaliplatin-based chemotherapy with regimens such as oxaplatin plus 5-fluorouracil/leucovorin have been shown to improve disease-free and overall survival in these stage III patients. This review will discuss the development of adjuvant chemotherapy in colon cancer, focusing on recent progress and particular topical issues related to its use in this disease, such as the use of surrogate end points for overall survival in contemporary clinical trials.

Substantial progress has been made in understanding the pathogenesis of malignant melanoma at the cellular level, leading to the development of several new agents in the treatment of melanoma. The focus of this review is to summarize the emerging therapies and investigational agents in the treatment of melanoma over the last 5 years.
