As tumors grow, they acquire mutations, some of which create neoantigens that influence the response of patients to immune checkpoint inhibitors. We explored the impact of neoantigen intratumor heterogeneity (ITH) on antitumor immunity. Through integrated analysis of ITH and neoantigen burden, we demonstrate a relationship between clonal neoantigen burden(More)
Eighteen patients who developed cutaneous reactions to red tattoos were studied to identify the chemicals responsible for the reactions to modern red tattoo pigments. Biopsies from the tattoos were examined histologically and the chemical composition of the red pigments was analysed by X-ray microanalysis. A variety of metallic elements including aluminium,(More)
The presence of multiple subclones within tumors mandates understanding of longitudinal and spatial subclonal dynamics. Resolving the spatial and temporal heterogeneity of subclones with cancer driver events may offer insight into therapy response, tumor evolutionary histories and clinical trial design.
Hypoxia contributes to the aggressive and treatment-resistant phenotype of pancreatic ductal adenocarcinoma. Oncolytic vaccinia virus has potential as an anti-tumour agent, but the ability to lyse hypoxic tumour cells is vital for clinical efficacy. We hypothesized that unique aspects of the poxvirus life cycle would protect it from attenuation in hypoxic(More)
PURPOSE The goal of this study was to explore the perspectives and practice of radiation oncologists who treat breast cancer patients who have had breast reconstruction. METHODS In 2010, an original electronic survey was sent to all physician members of the American Society of Radiation Oncology, National Cancer Research Institute-Breast Cancer Studies(More)
A patient with sarcoidosis who presented with a granulomatous tattoo reaction is described. Although tattoo granulomata usually represent a local hypersensitivity reaction to tattoo pigments, they can be a manifestation of systemic sarcoidosis. In this case the lesions were confined to the red areas of tattoos suggesting that tattoo sarcoid may be more than(More)
PURPOSE Vascular endothelial growth factor (VEGF) is an important hypoxia-inducible pro-angiogenic protein that has been linked with an adverse survival outcome after radiotherapy in other cancer types: we hypothesized that this may also occur in prostate cancer. A retrospective study was, therefore, carried out to evaluate the potential of tumor VEGF(More)
BACKGROUND AND AIMS Metastasis accounts for the poor outcome of patients with pancreatic cancer. We recently discovered PRSS3 to be over-expressed in metastatic human pancreatic cancer cells. This study aimed to elucidate the role of PRSS3 in the growth and metastasis of human pancreatic cancer. METHODS PRSS3 expression in human pancreatic cancer cell(More)
Vaccinia virus (VV) is an enveloped DNA virus from the poxvirus family and has played a crucial role in the eradication of smallpox. It continues to be used in immunotherapy for the prevention of infectious diseases and treatment of cancer. However, the mechanisms of poxvirus entry, the host factors that affect viral virulence, and the reasons for its(More)
