CONTEXT Hormonal therapy (HT) when added to radiation therapy (RT) for treating unfavorable-risk prostate cancer leads to an increase in survival except possibly in men with moderate to severe comorbidity. However, it is unknown which comorbid conditions eliminate this survival benefit. OBJECTIVE To assess whether neoadjuvant HT use affects the risk of(More)
PURPOSE To compare prostate-specific antigen (PSA) outcomes in a cohort of men with high-risk prostate cancer based on the presence or absence of any Gleason Grade 5 component (primary, secondary, or tertiary). METHODS AND MATERIALS Our study cohort consisted of 312 men with T1c-T3N0M0 prostate cancer with Gleason Scores of 7 with tertiary Grade 5, 8, or(More)
Tumor endothelial marker 1 (Tem1; endosialin) is the prototypical member of a family of genes expressed in the stroma of tumors. To assess the functional role of Tem1, we disrupted the Tem1 gene in mice by targeted homologous recombination. Tem1(-/-) mice were healthy, their wound healing was normal, and tumors grew normally when implanted in s.c. sites.(More)
Tumor endothelial marker (TEM)8 was uncovered as a gene expressed predominantly in tumor endothelium, and its protein product was recently identified as the receptor for anthrax toxin. Here, we demonstrate that TEM8 protein is preferentially expressed in endothelial cells of neoplastic tissue. We used the extracellular domain of TEM8 to search for ligands(More)
PURPOSE To identify clinical factors associated with prostate cancer-specific mortality (PCSM), adjusting for comorbidity, in elderly men with intermediate-risk prostate cancer treated with brachytherapy alone or in conjunction with external beam radiation therapy. METHODS AND MATERIALS The study cohort comprised 1,978 men of median age 71 (interquartile(More)
PURPOSE OF REVIEW Targeting the endothelial cells that line tumor infiltrating blood vessels is a new anticancer strategy that has gained widespread support from biologists and clinicians. Here we highlight different approaches currently being used to target tumor endothelium and discuss new avenues for intervention that have been opened through the recent(More)
The mechanisms by which inhibition of the epidermal growth factor receptor (EGFR) sensitizes non-small cell lung cancer (NSCLC) cells to ionizing radiation remain poorly understood. We set out to characterize the radiosensitizing effects of the tyrosine kinase inhibitor erlotinib and the monoclonal antibody cetuximab in NSCLC cells that contain wild-type(More)
BACKGROUND Neoadjuvant hormone therapy (NHT) use is associated with an increased risk of all-cause mortality (ACM) in men with a history of coronary artery disease (CAD)-induced congestive heart failure (CHF) or myocardial infarction (MI). However, its effect in men with no or at least a single risk factor for CAD stratified by prostate cancer (PCa)(More)
Tumor endothelial marker (TEM)8 was uncovered as a gene expressed predominantly in tumor endothelium, and its protein product was recently identified as the receptor for anthrax toxin. Here, we demonstrate that TEM8 protein is preferentially expressed in endothelial cells of neoplastic tissue. We used the extracellular domain of TEM8 to search for ligands(More)
BACKGROUND We report the outcome of a phase I/II clinical trial of stereotactic body radiation therapy (SBRT) for low (LR) and select intermediate risk (IR) prostate cancer (PCa) patients. PATIENTS AND METHODS Eligible patients included men with prostate adenocarcinoma with Gleason score 6 with PSA ≤ 20 or Gleason 7 with PSA ≤ 15 and clinical stage ≤ T2b.(More)
