Background: Adjuvant radiation therapy is proven to reduce local recurrence in patients with early stage breast cancer. To reduce toxicity, improve geographic accuracy, and reduce treatment time, IOERT can be utilized as an alternative to external beam radiation therapy. The study’s objective was to determine the short term toxicity and cosmesis profile of single fraction IOERT given as definitive treatment in a community setting. Materials and Methods: From Mar 2012 to Jul 2014, 84 patients (3 bilateral), ages 45-91 y.o. with stage 0-II were treated with IOERT (Mobetron, IntraOp Medical, Sunnyvale, CA). A single 21 Gy fraction was administered to …

Kiss1r Signaling Promotes Breast Cancer Metastasis, Cameron G-F Goertzen
Electronic Thesis and Dissertation Repository
Kisspeptins, peptide products of KISS1, are endogenous ligands for KISS1R, a G protein-coupled receptor. In numerous cancers, KISS1 acts as a metastasis suppressor. However, studies have revealed that patients with elevated KISS1 and KISS1R breast tumor expression have increased tumor grade, increased lymph node metastases and poor survival. We hypothesize that depletion of KISS1R inhibits breast cancer cell metastasis. In order to assess the role of KISS1R in breast cancer metastasis, we used a pre-clinical orthotopic xenograft mouse model using MDA-MB-231 breast cancer cells for breast tumor establishment. We discovered that depletion of KISS1R decreased primary tumor growth and …
Imbalance Between Neutrophil Elastase And Elafin Promotes Breast Cancer Growth And Progression, Joseph Anthony Caruso
Imbalance Between Neutrophil Elastase And Elafin Promotes Breast Cancer Growth And Progression, Joseph Anthony Caruso
Dissertations & Theses (Open Access)
Elafin, an endogenous serine protease inhibitor, is a critical component of the epithelial barrier against neutrophil elastase (NE) activity. The central hypothesis examined in this dissertation was that elafin has tumor suppressive properties in breast cancer. In support of this hypothesis, immunohistochemical (IHC) analysis revealed that elafin was downregulated in the majority of invasive breast tumors and a subset of pre-invasive ductal carcinoma in situ (DCIS) compared to elafin expression in the normal mammary epithelium. To understand the role of elafin in the mammary epithelium and the impetus for its downregulation during breast tumorigenesis, primary and immortalized human mammary epithelial …
