Journal ArticleDOI
Immunohistochemical expression of epidermal growth factor receptor (EGFR) and p53 in Gliomas and correlation with clinicopathological parameters
TL;DR: There was positive and negative correlation with expression of both EGFR & p53 in higher grades low grades of tumors, and both the markers were 100% positive in Grade III and Grade IV tumors.
Journal ArticleDOI

Jillian R. Gunther,Denise De La Cruz,David Boyce-Fappiano,Annette Eakes Ponnie,Letericia Smith,Emma B. Holliday,Andrew J. Bishop,Albert C. Koong,Prajnan Das,Chelsea C. Pinnix +9 more
TL;DR: Alternative virtual elective experiences allow MSs to informally evaluate medical subspecialties and could be offered even if formal elective opportunities are available.
Journal ArticleDOI

TL;DR: In this article , the authors utilized a novel digital spatial profiling technology on pretreatment anal cancer specimens to identify biomarkers associated with recurrence after chemoradiation, and found that the higher baseline expression of immune checkpoint biomarkers, together with markers of MAPK and PI3K/Akt activation (phospho-Akt) are associated with the recurrence following chemordiation for patients with localized squamous cell cancer of the anus.
Journal ArticleDOI

Derek J. Erstad,Mariela A. Blum,Jeannelyn S. Estrella,Prajnan Das,Bruce D. Minsky,Jaffer A. Ajani,Paul F. Mansfield,Brian D. Badgwell,Naruhiko Ikoma +8 more
TL;DR: In this article, the authors evaluated the prognostic markers for disease recurrence and survival in a cohort of node-negative gastric cancer patients (ypT0-4N0M0).
Journal ArticleDOI
Patient-Reported Outcomes After Chemoradiation in Patients With Anal Cancer: A Qualitative Analysis
Kelsey L. Corrigan,Brian De,Michael K. Rooney,Ethan B. Ludmir,Prajnan Das,Grace L. Smith,Cullen M. Taniguchi,Bruce D. Minsky,Eugene J. Koay,Albert C. Koong,Emma B. Holliday +10 more
TL;DR: In this paper , the authors conducted a survey study with qualitative analysis of free-text responses to explore themes of patient perceptions of their QOL during and after pelvic chemoradiation therapy to inform future interventions, reform patient education, and improve outcomes.
