Expanding The Capacity Of Rural Cancer Care With Teleoncology, Jason Semprini

Online Journal of Rural Research & Policy

Background: In the United States, 6 of the 25 leading causes of death stem from site-specific cancers, resulting in over 1.7 million deaths annually. Yet, this burden is not evenly distributed. While the incidence of cancer is significantly higher in urban areas, rural regions face higher rates of cancer mortality. Identifying the factors contributing rural cancer disparities can facilitate more effective and feasible policy solutions.’

Problem Definition: Rural Americans are geographically isolated from high-quality cancer services and face systemic barriers to NCI designated comprehensive cancer centers. Given this disparity, rural Americans have failed to fully realize the benefits of ...

Black Women Survive Breast Cancer With Community-Based Care, Shelley I. White-Means, Jill Dapremont, Barbara D. Davis, Tronlyn Thompson

Faculty Presentations

PURPOSE Community-based breast cancer support agencies who address non-medical, social determinants of health needs that serve as barriers to maximizing breast health outcomes may play a vital role in mitigating breast cancer mortality. They share a common emphasis on addressing social, economic, and psychological needs of breast cancer survivors and those at risk of breast cancer. This paper is third in a series of papers exploring why the rate of breast cancer mortality is two times higher for African American women than white women in Memphis. We sought insights from community-based breast cancer support agencies because they have a close-up ...

Swimming Pool Environment And Respiratory Health Issues Experienced By Masters Swimmers: Results From A Literature Review And Survey Of United States Masters Swimming Clubs, Jody C. Gan, Julia Snegg, William Harder

International Journal of Aquatic Research and Education

After three members of a Masters adult swim club died of lung cancer, both a literature review and survey were conducted with representatives from 746 United States Masters Swimming clubs to explore a possible relationship between swimming and cancers of the respiratory tract. Six other clubs reported known cancers of the respiratory tract among club members, but none of the other 740 clubs reported a similar cluster of lung cancer. More clubs reported cases of chronic respiratory infections and widespread complaints about air quality. While no studies exploring a relationship between swimming and lung cancer could be found in the ...

How Can We Stop Cancer?, Joseph R. Current

The Review: A Journal of Undergraduate Student Research

Cancer is a disease that humans have been struggling to combat for centuries. It originates from the accumulation of several mutations over the life of a cell that causes it to evade cell death and multiply rapidly. It can affect any tissue in the body and can spread to other parts of the body through metastasis. Cancer comes in numerous shapes and sizes with different levels of aggression, growth speeds, and health risks. Many treatments for cancer exist today, three of the most popular being surgery, chemotherapy, and radiation therapy, which can be used in combinations with other treatments to ...

Cervical Cancer Recurrence In The Colon, Samantha A. Erb Do, Shreyash Pandya Md, Johnny Johnson Md

West Florida Division Virtual Research Day

Cervical cancer is the fourth leading cancer worldwide in women, ranking only after breast cancer, colorectal cancer, and lung cancer. Because it is typically diagnosed at a younger age compared to other major cancer types, it leads to a proportionally greater loss in life-years. Most cancers occur in squamo-columnar junction, the transition point between squamous and columnar cells; squamous cell carcinoma accounts for approximately 70% of cervical cancer cases. Treatment options vary depending on the stage at diagnosis and include surgery (conization or hysterectomy), radiation, chemotherapy, targeted therapy, and immunotherapy. Prognosis is affected by stage, tumor volume, age and performance ...

West Florida Division Virtual Research Day

In the U.S., excluding melanoma, lung cancer is the leading cause of cancer-related deaths.¹
Cigarette smoking is the number one risk factor and is linked to 80-90% of lung cancer deaths.²
Low-dose Computerized Tomography has been shown to reduce lung cancer deaths by 20% in randomized control trials and observational studies.⁴
The U.S. Preventative Task Force recommends annual screening for lung cancer with low-dose computerized tomography (LDCT) in adults ages 55-80 years of age who:

• Have a 30 pack-year smoking history and
• Currently smoke or
• Have quit within the past 15 years.

Malignant Degeneration Of Spiradenoma Of The Eyebrow, Christopher White Do, Kristin Witfill Do, Richard Miller Do

West Florida Division Virtual Research Day

Spiradenocarcinoma is a malignancy of eccrine origin, with only 120 reported cases in the literature.¹ Elderly males and females are equally affected.² Benign spiradenomas along with their malignant counterpart are more frequent in patients with Brooke-Spiegler syndrome or familial eccrine spiradenoma, owing to the increased incidence of folliculosebaceous-apocrine tumors seen with these entities.³

A Rare Case Of Primary Cutaneous Mucoepidermoid Carcinoma, Hassie Cooper Do, Maheera Farsi Do, Richard Miller Do, Pay Kamrani, Dudith Pierre Victor

West Florida Division Virtual Research Day

Mucoepidermoid carcinoma (MEC) is a well-documented malignant tumor commonly found in the salivary glands. Cutaneous involvement is very rare, especially when presenting as a primary cutaneous neoplasm. Gallagher first described primary cutaneous MEC in 1959 and since then, to the best of our knowledge, there have been approximately 20 reports published in the literature. Here we present a very rare case of primary cutaneous mucoepidermoid carcinoma.

Acral lentiginous melanoma (ALM), named for its location and histological growth pattern, is a rare variant of melanoma. ALM presents on palms, soles, or in association with the nail unit.1 While ALM accounts for approximately 5% of melanomas diagnosed each year, it is the most commonly diagnosed subtype of melanoma in non-Caucasian patients.

Dgat Activity Is Dispensable For Myeloma Cell Proliferation, C S. Murphy, H Campbell, V Demambro, M Farrell, S Costas, C Vary, M R. Reagan

Costas T. Lambrew Research Retreat 2020

Multiple myeloma (MM) is the third most common blood cancer and is defined by the clonal expansion of malignant plasma cells in the bone marrow (BM). MM remains incurable due to the development of resistance to current chemotherapies; therefore, it is paramount to investigate novel treatments and the mechanisms of drug resistance in multiple myeloma cells. Recently, changes in both catabolic and anabolic lipid metabolism have been shown to support the proliferation, migration and the development of drug resistance in breast, prostate, and ovarian cancer. However, the role of lipid metabolism in myeloma cells has been understudied. Given the data ...

Association Of Race/Ethnicity And Population Density With Disparities In Timeliness Of Rectal Cancer Therapy, Susanna S. Hill

GSBS Dissertations and Theses

Objective:

Access to care is key to effective rectal cancer treatment. We hypothesized that ethnic/racial minorities living in high population density areas would have the greatest delays in cancer care compared to whites living in medium population density areas.

Methods:

Using 2004-2016 National Cancer DataBase data, we identified stage I-III patients with invasive rectal adenocarcinoma who underwent surgery. The data were analyzed by race/ethnicity (whites, blacks, or Hispanics) and population density (metropolitan or urban/rural). Multivariable ANCOVA was performed to evaluate the duration of time from diagnosis to surgery.

Results:

The study population consisted of 76,131 patients ...

Data Analysis Of A National Health And Nutrition Examination Survey (Nhanes) To Identify The Relationship Between Obesity And Cancer, Reyhaneh A. Yazdi, Ramona Stone

Objective: To examine the relationship of cancer and obesity using BMI and Waist Circumference (WC) as indicators using the National Health and Nutrition Examination Survey (NHANES) dataset.

Method: NHANES (2013-2014) dataset was used to obtain information on BMI, Waist Circumference (WC), and cancer (presence or absence) among the participants. The prevalence of obesity and cancer was tested with Pearson λ^2 test and the relationship of these two with education (5 levels) was ...

Can Magnetic Resonance Imaging Predict Pathologic Findings For Endometrioid Endometrial Cancer?, Elizabeth L. Dickson Michelson, Jessica J. F. Kram, Kayla Heslin, David Baugh, Vikram Bamra, Jiahao Hu, Abhishek Shukla, Scott A. Kamelle

Journal of Patient-Centered Research and Reviews

This pilot study aimed to assess the feasibility of precisely measuring tumor diameter and myometrial invasion in patients with endometrioid endometrial cancer (EEC) using preoperative contrast-enhanced magnetic resonance imaging (MRI). Adult patients with confirmed diagnosis of complex hyperplasia with atypia or EEC were included. Three radiologists separately measured tumor diameter and myometrial invasion. Basic descriptive statistics were used to describe patient characteristics and to compare radiology- and pathology-measured tumor diameter and myometrial invasion. Using the pathology results for tumor diameter as the gold standard for comparison, at least 1 radiologist was able to predict largest tumor diameter within 5 mm ...

Genetic Relationships And Therapeutic Options For Relapsed Acute Lymphoblastic Leukemia, Hailie Shertzer

Senior Honors Theses

Acute lymphoblastic leukemia (ALL) is the most common form of cancer among children and can be lethal to the adult population. Though 80% of patients with ALL reach complete remission after treatment, about 20% of those diagnosed fail to remain cancer-free. Genetic rearrangements are the hallmark of relapsed ALL, but the mechanism by which these rearrangements occur is still unclear. Recent research suggests these mutations may be detectable during initial diagnosis. If researchers are able to accurately assess the probability of relapse during diagnosis by analyzing the genome of the leukemic cells, the likelihood of administering effective therapy would increase ...

BACKGROUND: Racial and socioeconomic disparities in breast cancer mortality persist. In Boston, MA, Black, Non-Hispanic women and Medicaid-insured individuals are 2-3 times more likely to have delays in treatment compared to White or privately insured women. While evidence-based care coordination strategies for reducing delays exist, they are not systematically implemented across healthcare settings.

METHODS: Translating Research Into Practice (TRIP) utilizes community engaged research methods to address breast cancer care delivery disparities. Four Massachusetts Clinical and Translational Science Institute (CTSI) hubs collaborated with the Boston Breast Cancer Equity Coalition (The Coalition) to implement an evidence-based care coordination intervention for Boston residents ...

A Unique Presentation Of Cutaneous Diffuse Large B-Cell Lymphoma, Mary Awad, Erik Holzwanger, Sandeep Jubbal

Open Access Articles

Cutaneous B-cell lymphomas (CBCL) are rare heterogeneous neoplastic diseases composing about 22.5% of all cutaneous lymphomas. These diseases can be divided into primary and secondary cutaneous variants with primary cutaneous B-cell lymphoma (PCBCL) divided into three distinct entities including primary cutaneous marginal zone lymphoma, primary cutaneous follicle center lymphoma, and primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT). Secondary cutaneous diffuse large B-cell lymphoma (CDLBCL) and PCDLBCL, LT are more aggressive neoplasms compared to the aforementioned CBCL with survival rates of 37% and 50% after 5 years, respectively. CDLBCL can present as cutaneous or subcutaneous nodules, papular ...

Atrx Loss In Pediatric Glioma Results In Epigenetic Dysregulation Of G2/M Checkpoint Maintenance And Sensitivity To Atm Inhibition, Brendan Mullan, Tingting Qin, Ruby Siada, Carla Danussi, Jacqueline Brosnan-Cashman, Drew Pratt, Taylor Garcia, Viveka Nand Yadav, Xinyi Zhao, Meredith Morgan, Sriram Venneti, Alan Meeker, Alnawaz Rehemtulla, Pedro Lowenstein, Maria Castro, Carl Koschmann

Medical Student Research Symposium

ATRX is a histone chaperone protein recurrently mutated in pediatric glioma. The mechanism which mediates the proliferative advantage of ATRX loss in pediatric glioma remains unexplained. Recent data revealed a distinct pattern of DNA binding sites of the ATRX protein using ChIP-seq in mouse neuronal precursor cells (mNPCs). Using the ATRX peaks identified in p53^-/- mNPCs, we confirmed that ATRX binding sites were significantly enriched in gene promoters (p < 0.0001) and CpG islands (p < 0.0001) compared with random regions. Gene set enrichment (GSE) analysis identified that cell cycle and regulation of cell cycle were among the most significantly enriched gene sets (p=2.52e-16 and 1.61e-9, respectively). We found that ATRX loss resulted in dysfunction of G2/M checkpoint maintenance: (1) ATRX-deficient pediatric glioblastoma (GBM) cells exhibited a seven-fold increase in mitotic index at 16 hours after sub-lethal radiation, and (2) murine GBM cells with ATRX knockdown demonstrated impaired pChk1 signaling on western blot at multiple time points after radiation compared to controls (p=0.0187). Notably, the ATM signaling (pChk2) remained intact in those cells, suggesting a potential therapeutic target. ATRX-deficient mouse cells were uniquely sensitive to ATM inhibitors at 1 uM alongside 8 Gy radiation compared to controls with intact ATRX (AZD0156: p=0.0027 and AZD01390: p=0.0436). Mice intra-cranially implanted with ATRX-deficient GBM cells showed improved survival (n=10, p=0.0018) when treated with AZD0156 combined with radiation. Our findings suggest that ATRX loss in glioma results in unique sensitivity to ATM inhibition via epigenetic dysregulation of G2/M checkpoint maintenance.

Medical Student Research Symposium

INTRODUCTION AND OBJECTIVE: Ductal adenocarcinoma is considered a rare histological variant of prostate adenocarcinoma (PCa). Given the rarity of this subtype, optimal treatment strategies for men with nonmetastatic ductal PCa is largely unknown. We aimed to describe the impact of surgery, radiotherapy, and systemic therapy on overall survival (OS) in men with nonmetastatic ductal PCa.

METHODS: We retrospectively selected 2209 cases of ductal PCa, diagnosed between 2004 and 2015, within the National Cancer Database (NCDB). Exclusion of metastatic patients yielded a total sample of 1993 individuals. Cox regression analysis tested the impact of treatment (surgery, radiotherapy, systemic therapy and no ...
