Colocolic Fistula: A Rare Consequential Presentation Of Cecal Mucinous Adenocarcinoma, Jessica Rutyna, Paige Stratton, Rutwik Pradeep Sharma, Anthony V. Baratta Jr

Advances in Clinical Medical Research and Healthcare Delivery

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States. Relative to a 5-year survival rate, CRC patients diagnosed with localized disease accrue a 90% survival rate while those diagnosed with distant-stage disease maintain 14% survival. Mucinous adenocarcinoma (MAC) is a unique subtype of CRC characterized by the presence of extracellular mucin occupying 50% of tumor expansion. Fistula complications of colonic malignancy have rarely been reported and more commonly occur as complications of diverticulitis. Colocolic fistulae are atypical consequences of colon cancer, which have been rarely reported. We wish to report a unique case …

Implementation Of Standardized Patient Education To Improve Adherence With Colonoscopy For Colorectal Cancer Screening, Melissa Leal Hearn, Melissa M. Hessock, Tara L. Hahn

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

BACKGROUND: Colorectal cancer (CRC) is the third leading cause of cancer deaths among men and women in the U.S. CRC is preventable and manageable when detected early. Approximately 30% of average-risk Americans are overdue for colonoscopy screening. Colonoscopy screenings can reduce death by 67%. Current evidence suggests CRC screening education improves screening uptake among men and women at average-risk age.

LOCAL PROBLEM: The setting of this practice improvement project was a private colorectal surgery practice in South Texas, serving primarily Hispanic/Latino and Caucasian patients. Cancellation rates before colonoscopy were 16.8%, and there was no standardized education for CRC …

Periodontal Status And Inflammatory Markers In Gingival Crevicular Fluid Of Patients With Periodontitis And Colorectal Cancer, Sandu Râmboiu, Flavia Mirela Nicolae, Andrada Soancă, Dorin Nicolae Gheorghe, Dora Maria Popescu, Bogdan Silviu Ungureanu, Dragoș Nicolae Mărgăritescu, Adina Turcu-Știolica, Mihail Virgil Boldeanu, Valeriu Marin Șurlin, Dan Ionuț Gheonea, Petra Șurlin

Objectives. The present pilot study was carried out to evaluate the periodontal status, the levels of interleukin-6 and tumor necrosis factor alpha in gingival crevicular fluid on hospitalized patients with colorectal cancer. Materials and Methods. The sample of our study was represented by 74 patients with colorectal cancer. They were assigned to one of the two study groups, based on cancer’s stages, as follows: (i) stage III-IV: 51 patients (A-group); (ii) stage I-II: 23 patients (B-group). For each participant periodontal parameters were recorded and gingival crevicular fluid samples were collected and immunologically assessed. Results. Statistically significant differences were found between …

Braf D594a Mutation Defines A Unique Biological And Immuno-Modulatory Subgroup Associated With Functional Cd8+ T Cell Infiltration In Colorectal Cancer, Wenjing Li, Chenyi Zhao, Wenhui Li, Yang Gong, Kaili Ma, Yujie Lu, Xiaowei Liu, Lianjun Zhang, Feng Guo

Student and Faculty Publications

BACKGROUND: BRAF non-V600 mutation occupies a relatively small but critical subset in colorectal cancer (CRC). However, little is known about the biological functions and impacts of BRAF class III mutation in CRC. Here, we aim to explore how D594A mutation impacts on biological behaviors and immune related signatures in murine CRC cells.

METHODS: BRAF V600E (class I), G469V (class II) and D594A (class III) mutant cell lines were established based on MC38 cells. The biological behaviors of cells were evaluated in respect of cell growth, cell proliferation, cell apoptosis, cell migration and invasion by the methods of colony-forming assay, CCK-8 …

Matrix Gla Protein – A New Marker For Colorectal Cancer Detection? A Systematic Review, Mirela-Georgiana Perné, Lorena Ciumărnean, Olga-Hilda Orășan, Vasile Negrean, Teodora-Gabriela Alexescu, Mircea Vasile Milaciu, Ioana Roșca, Răzvan Dan Togănel, Gabriel Emil Petre, Lucia Procopcoiuc, Cristina Drugan, Alexandra Crăciun

Background. Colorectal cancer is a real public health issue, with high morbidity and severe impact on quality of life. Although mortality from this type of cancer is decreasing due to modern diagnostic and treatment methods, the understanding of its genetic and molecular mechanisms is important to develop a broader range of diagnostic and therapeutic approaches. Genetic therapy is an important strategy in cancer treatment, and the matrix Gla protein (MGP) gene expression has been described in numerous studies as increased in tumour pathology. In this article, we have summarized the currently available evidence on the connection between MGP and colorectal …

Colon Cancer Screening And The Association With Colon Cancer Incidence And Mortality Rates In Ethnic Minority Groups, Jovonne Smith

Student Scholar Showcase

Colorectal cancer (CRC) continues to be a public health burden and is the second leading cause of American cancer deaths. Strides have been made in the medical community, and there has been an overall decrease in CRC rates. This decrease is primarily due to a cumulative decline in late-onset colorectal cancer diagnosis (LOCRC), defined as CRC cancer in adults over the age of 50 years. CRC continues to burden American Indians and Alaska Natives (AIAN) and Non-Hispanic Black individuals (NHB) disproportionately. The incidence and mortality rates remain disproportionately higher than other ethnic groups, and the survival rate is lower than …

Targeted Exome-Based Predictors Of Patterns Of Progression Of Colorectal Liver Metastasis After Percutaneous Thermal Ablation, Iwan Paolucci, Yuan-Mao Lin, Yoshikuni Kawaguchi, Harufumi Maki, A Kyle Jones, Marco Calandri, Scott Kopetz, Timothy E Newhook, Kristy K Brock, Jean-Nicolas Vauthey, Bruno C Odisio

Student and Faculty Publications

BACKGROUND: Percutaneous thermal ablation is a curative-intent locoregional therapy (LRT) for selected patients with unresectable colorectal liver metastasis (CLM). Several factors have been identified that contribute to local tumour control after ablation. However, factors contributing to disease progression outside the ablation zone after ablation are poorly understood.

METHODS: In this retrospective study, using next-generation sequencing, we identified genetic biomarkers associated with different patterns of progression following thermal ablation of CLM.

RESULTS: A total of 191 ablation naïve patients between January 2011 and March 2020 were included in the analysis, and 101 had genomic profiling available. Alterations in the TGFβ pathway …
