Journal ArticleDOI
Photodynamic therapy of cancer: An update†‡
Patrizia Agostinis,Kristian Berg,Keith A. Cengel,Thomas H. Foster,Albert W. Girotti,Sandra O. Gollnick,Stephen M. Hahn,Michael R. Hamblin,Michael R. Hamblin,Asta Juzeniene,David Kessel,Mladen Korbelik,Johan Emelian Moan,Johan Emelian Moan,Pawel Mroz,Dominika Nowis,Jacques Piette,Brian C. Wilson,Jakub Golab,Jakub Golab +19 more
TL;DR: The photodynamic therapy (PDT) is a clinically approved, minimally invasive therapeutic procedure that can exert a selective cytotoxic activity toward malignant cells as discussed by the authors, which can prolong survival in patients with inoperable cancers and significantly improve quality of life.
Journal ArticleDOI
Radiation and dual checkpoint blockade activate non-redundant immune mechanisms in cancer

TL;DR: Major tumour regressions are reported in a subset of patients with metastatic melanoma treated with an anti-CTLA4 antibody and radiation and reproduced this effect in mouse models, showing that PD-L1 on melanoma cells allows tumours to escape anti- NCTLA4-based therapy, and the combination of radiation, anti- CTLA4 and anti-PD-L 1 promotes response and immunity through distinct mechanisms.
Journal ArticleDOI
National Institutes of Health State-of-the-Science Conference Statement: Diagnosis and Management of Ductal Carcinoma In Situ September 22–24, 2009

TL;DR: The primary question for future research must focus on the accurate identification of patient subsets diagnosed with DCIS, including those persons who may be managed with less therapeutic intervention without sacrificing the excellent outcomes presently achieved.
Journal ArticleDOI
Hypoxia is important in the biology and aggression of human glial brain tumors.
Sydney M. Evans,Kevin Judy,Isolde Dunphy,W. Timothy Jenkins,Wei-Ting Hwang,Peter T. Nelson,Robert A. Lustig,Kevin Jenkins,Deirdre P. Magarelli,Stephen M. Hahn,Ruth A. Collins,M. Sean Grady,Cameron J. Koch +12 more
TL;DR: A correlation between more rapid tumor recurrence and hypoxia was demonstrated with EF5 binding, but this relationship was not predicted by Eppendorf measurements.
Journal ArticleDOI
Inhibition of oxygen-dependent radiation-induced damage by the nitroxide superoxide dismutase mimic, Tempol
James B. Mitchell,William DeGraff,Dwight Kaufman,Murali Krishna,Amram Samuni,Eli Finkelstein,Min S. Ahn,Stephen M. Hahn,Janet Gamson,Angelo Russo +9 more
TL;DR: Tempol represents a new class of non-thiol-containing radiation protectors, which may be useful in elucidating the mechanism(s) of radiation-induced cellular damage and may have broad applications in protecting against oxidative stress.
