PURPOSE Adoptive T-cell immunotherapy with tumor infiltrating lymphocytes or genetically-modified T cells has yielded dramatic results in some cancers. However, T cells need to traffic properly into tumors to adequately exert therapeutic effects. EXPERIMENTAL DESIGN The chemokine CCL2 was highly secreted by malignant pleural mesotheliomas (MPM; a planned(More)
INTRODUCTION Survival after pulmonary metastasectomy for soft tissue sarcoma (STS) has been lower than in osteosarcoma (14-40% versus 40-50%). With improved patient selection criteria and advanced chemotherapy agents, we hypothesized that survival after metastasectomy for STS has improved in recent years. METHODS Retrospective study of 48 patients(More)
Transforming growth factor (TGF)-β is a potent immunosuppressive cytokine necessary for cancer growth. Animal and human studies have shown that pharmacologic inhibition of TGF-β slows the growth rate of established tumors and occasionally eradicates them altogether. We observed, paradoxically, that inhibiting TGF-β before exposing animals to tumor cells(More)
Each year, more than 700,000 people undergo cancer surgery in the United States. However, more than 40% of those patients develop recurrences and have a poor outcome. Traditionally, the medical community has assumed that recurrent tumors arise from selected tumor clones that are refractory to therapy. However, we found that tumor cells have few phenotypical(More)
This year approximately 569,490 Americans, more than 1,500 people per day, are expected to die of cancer. Cancer has supplanted heart disease as the leading cause of death in the United States in men and women younger than age 85 years (American Cancer Society, Facts and Figures 2010). Cancer also has a major economic impact on the U.S. economy, with 2010(More)
BACKGROUND The virtual patient (VP) is a web-based tool that allows students to test their clinical decision-making skills using simulated patients. METHODS Three VP cases were developed using commercially available software to simulate common surgical scenarios. Surgical clerks volunteered to complete VP cases. Upon case completion, an individual(More)
Surgery is the most effective therapy for cancer in the United States, but disease still recurs in more than 40% of patients within 5 years after resection. Chemotherapy is given postoperatively to prevent relapses; however, this approach has had marginal success. After surgery, recurrent tumors depend on rapid neovascular proliferation to deliver nutrients(More)
Forkhead box P3 (Foxp3)(+) T regulatory (T(reg)) cells maintain immune homeostasis and limit autoimmunity but can also curtail host immune responses to various types of tumors. Foxp3(+) T(reg) cells are therefore considered promising targets to enhance antitumor immunity, and approaches for their therapeutic modulation are being developed. However, although(More)
PURPOSE Prolonged radiation treatment (RT) time (RTT) has been associated with worse survival in several malignancies. The present study investigated whether delays during RT are associated with overall survival (OS) in non-small cell lung cancer (NSCLC). METHODS AND MATERIALS The National Cancer Database was queried for patients with stage III NSCLC who(More)
Esophageal carcinoma is the most rapidly increasing tumor in the United States and has a dismal 15% 5-year survival. Immunotherapy has been proposed to improve patient outcomes; however, no immunocompetent esophageal carcinoma model exists to date to test this approach. We developed two mouse models of esophageal cancer by inoculating immunocompetent mice(More)
