A phase I clinical trial of single-dose intrapleural IFN-beta gene transfer for malignant pleural mesothelioma and metastatic pleural effusions: high rate of antitumor immune responses.

Purpose: This phase 1 dose escalation study evaluated the safety and feasibility of single-dose intrapleural IFN-beta gene transfer using an adenoviral vector (Ad.IFN-beta) in patients with malignant pleural mesothelioma (MPM) and metastatic pleural effusions (MPE).

Experimental Design: Ad.

Immunosurveillance and survivin-specific T-cell immunity in children with high-risk neuroblastoma.

Purpose: Tumor immunosurveillance influences oncogenesis and tumor growth, but it remains controversial whether clinical failure of immunosurveillance is a result of lymphocyte dysfunction or tumor escape. In this study, our goal was to characterize the physiology of tumor immunosurveillance in children with high-risk neuroblastoma (HR-NBL).

Patients And Methods: Immunohistopathologic studies were carried out on 26 tumor samples from a cohort of HR-NBL patients diagnosed at Children's Hospital of Philadelphia for the 2-year period from May 2003 to May 2005.

Interferon beta adenoviral gene therapy in a patient with ovarian cancer.

Background A 47-year-old woman with a history of ovarian cancer and a 6-year disease-free remission presented with dyspnea and increased abdominal girth. The patient was found to have ascites and a large left pleural effusion, both of which contained malignant cells consistent with recurrent ovarian cancer. Her disease progressed despite treatment with chemotherapeutic and hormonal agents.
