Excerpt
Despite aggressive multi-modality therapy including image-guided surgical resection, maximum external beam radiation therapy, and prolonged cycles of adjuvant chemotherapy, the prognosis for patients diagnosed with malignant brain tumors remains poor [
1]. In patients with malignant brain tumors, the normal brain parenchyma is deeply infiltrated by invasive tumor cells. Therefore, treatments that specifically target cancer cells without harming the surrounding normal brain are critically needed. Immunotherapy targeting tumor-specific antigens is a modality that can meet this specificity by taking advantage of the exquisite precision of the human immune system in targeting cells for cytolytic destruction. Currently, studies have demonstrated the feasibility of activating the immune system to eliminate tumors [
2], and future efforts are aimed at identifying potential target antigens and maximizing the effectiveness of immunotherapy. Survivin was identified over a decade ago as an inhibitor of apoptosis that promotes tumorigenesis [
3], and has been used as an antigenic target for immunotherapy in a variety of cancers such as pancreatic, gastric, and lung cancer [
4‐
6]. However, immunotherapy efforts targeting survivin in patients with malignant brain tumors are relatively devoid despite considerable rationale for exploitation of this frequently over-expressed tumor antigen. In this review, we have summarized the data supporting the potential of survivin as an immunotherapeutic target antigen for adult and pediatric brain tumors. …
