Metastatic prostate cancer is lethal and lacks effective strategies for prevention or treatment, requiring novel therapeutic approaches. Interleukin-6 (IL-6) is a cytokine that has been linked with prostate cancer pathogenesis by multiple studies. However, the direct functional roles of IL-6 in prostate cancer growth and progression have been unclear. In the present study, we show that IL-6 is produced in distant metastases of clinical prostate cancers. IL-6-activated signaling pathways in prostate cancer cells induced a robust 7-fold increase in metastases formation in nude mice. We further show that IL-6 promoted migratory prostate cancer cell phenotype, including increased prostate cancer cell …

Dimarino

Department of Medicine Faculty Papers

The ultimate goal of antiviral therapy for chronic hepatitis B (CHB) is prevention of hepatocellular carcinoma (HCC). Earlier we reported favorable effects of antiviral therapy on survival of HCC patients following curative tumor ablation (Int J Cancer online 14 April 2010; doi: 10.1002/ijc.25382). It was the first observation made in the United States. We now report 12 year follow-up of this patient group. CHB patients with no prior antiviral therapy with a single HCC (≤ 7 cm) were studied. All patients underwent local tumor ablation as their first option. Patients diagnosed before 1999 received no antiviral treatment while those diagnosed …

Feasibility Of Pulsed Proton Induced Acoustics For 3d Dosimetry, Fahed M. Alsanea

Open Access Theses

Proton therapy has the potential to deposit its energy in tissue with high conformity to the tumor and significantly reduced integral dose to normal tissue compared to conventional radiation, such as x-rays. As a result, local control can be enhanced while reducing side-effects and secondary cancers. This is due to the way charged Particles deposit their energy or dose, where protons form a Bragg peak and establish a well-defined distal edge as a function of depth (range). To date, the dose delivered to a patient from proton therapy remains uncertain, in particular the positioning of the distal edge of the …

The Cancer Care Workforce In Nebraska, Aastha Chandak, Fausto R. Loberiza Jr., Marlene Deras, James O. Armitage, Julie M. Vose, Jim P. Stimpson

Reports: Center for Health Policy

Although cancer is the leading cause of death in Nebraska, the adequacy of Nebraska’s cancer care workforce to care for the cancer population is unknown. Therefore, we used workforce survey data for 2008-2012 from the Health Professions Tracking Service to analyze the cancer care workforce supply in Nebraska. We found that from 2008 to 2012, the cancer care workforce for adults outpaced cancer prevalence. We outline several policy options to improve Nebraska’s cancer care workforce capacity, and we consider the effect the Affordable Care Act may have on Nebraska’s cancer care workforce

A Novel Curcumin Analog (H-4073) Enhances The Therapeutic Efficacy Of Cisplatin Treatment In Head And Neck Cancer, Bhavna Kumar, Arti Yadav, Kalman Hideg, Periannan Kuppusamy

Dartmouth Scholarship

Chemotherapy constitutes the standard modality of treatment for localized head and neck squamous cell carcinomas (HNSCC). However, many patients fail to respond and relapse after this treatments due to the acquisition of chemo- resistance. Therefore, there is an urgent need to develop novel drugs that could reverse the resistant phenotype. Curcumin, the constituent of the spice turmeric has been shown to have anti-inflammatory, anti-oxidant and anti-proliferative properties in several tumor types. However, use of curcumin has been limited due to its poor bio-absorption. Recently, a novel class of curcumin analogs, based on diarylidenylpiperidones (DAP), has been developed by incorporating a …

Characterization Of Iron Response In Gynecological Cell Lines, Kyle A. Bauckman

USF Tampa Graduate Theses and Dissertations

Ovarian carcinoma afflicts over 22,000 women each year with a 5 year survival rate of only 18% for stage IV patients [23]. Current treatment options are limited due to high rates of drug resistance and recurrence. Further, the identity of "precursor lesions" which give rise to various subclasses of epithelial ovarian cancer has been evasive. This is due to discovery of the cancer at already an advanced stage. Interestingly, endometriosis a benign but invasive gynecological disease has been described as a "precursor lesion" in the development of specific subtypes of ovarian cancer. Endometriotic cyst development involves the accumulation of "old …

Redox-Mediated And Ionizing-Radiation-Induced Inflammatory Mediators In Prostate Cancer Development And Treatment, Lu Miao, Aaron K. Holley, Yanming Zhao, William H. St. Clair, Daret K. St. Clair

Toxicology and Cancer Biology Faculty Publications

SIGNIFICANCE: Radiation therapy is widely used for treatment of prostate cancer. Radiation can directly damage biologically important molecules; however, most effects of radiation-mediated cell killing are derived from the generated free radicals that alter cellular redox status. Multiple proinflammatory mediators can also influence redox status in irradiated cells and the surrounding microenvironment, thereby affecting prostate cancer progression and radiotherapy efficiency.

RECENT ADVANCES: Ionizing radiation (IR)-generated oxidative stress can regulate and be regulated by the production of proinflammatory mediators. Depending on the type and stage of the prostate cancer cells, these proinflammatory mediators may lead to different biological consequences ranging from …

Microbiota, Oral Microbiome, And Pancreatic Cancer, Dominique S. Michaud, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Only 30% of patients diagnosed with pancreatic cancer survive one year post-diagnosis. Progress in understanding the causes of pancreatic cancer has been made, including solidifying the associations with obesity and diabetes, and a proportion of cases should be preventable through lifestyle modifications. Unfortunately, identifying reliable biomarkers of early pancreatic cancer has been extremely challenging, and no effective screening modality is currently available for this devastating form of cancer. Recent data suggest the microbiota may play a role in the disease process, but many questions remain. Future studies focusing on the human microbiome, both etiologically and as a marker of disease …

If you or your patients wish to consider Cryo Surgery, be sure to discuss this option with an urologist who performs Cryo Surgery of the prostate. Many urologists have not observed or been trained in the performance of this procedure. Prostate cancer allows you time to carefully consider all treatment options. Make an educated decision!

Metabotropic Glutamate Receptor-1 As A Novel Target For The Antiangiogenic Treatment Of Breast Cancer, Cecilia L. Speyer, Ali H. Hachem, Ali A. Assi, Jennifer S. Johnson, John Austin Devries, David H. Gorski

Department of Surgery

Metabotropic glutamate receptors (mGluRs) are normally expressed in the central nervous system, where they mediate neuronal excitability and neurotransmitter release. Certain cancers, including melanoma and gliomas, express various mGluR subtypes that have been implicated as playing a role in disease progression. Recently, we detected metabotropic glutamate receptor-1 (gene: GRM1; protein: mGluR1) in breast cancer and found that it plays a role in the regulation of cell proliferation and tumor growth. In addition to cancer cells, brain endothelial cells express mGluR1. In light of these studies, and because angiogenesis is both a prognostic indicator in cancer correlating with a poorer …

Introduction: Currently there are several advanced guiding techniques for pathoanatomical diagnosis of incidental solitary pulmonary nodules (iSPN): Electromagnetic navigation (EMN) with or without endobronchial ultrasound (EBUS) with miniprobe, transthoracic ultrasound (TTUS) for needle approach to the pleural wall and adjacent lung and computed tomography (CT)-guidance for (seldom if ever used) endobronchial or (common) transthoracical approach. In several situations one technique is not enough for efficient diagnosis, therefore we investigated a new diagnostic technique of endobronchial guided biopsies by a Cone Beam Computertomography (CBCT) called DynaCT (SIEMENS AG Forchheim, Germany). Method and Material: In our study 33 incidental solitary pulmonary nodules …

Oncology Faculty Publications

Malignant pleural mesothelioma (MPM) is an asbestos-related thoracic malignancy that is characterized by late metastases, and resistance to therapeutic modalities. The toxic side-effects of MPM therapies often limit their clinical effectiveness, thus necessitating development of new agents to effectively treat and manage this disease in clinic. CARP-1 functional mimetics (CFMs) are a novel class of compounds that inhibit growth of diverse cancer cell types. Here we investigated MPM cell growth suppression by the CFMs and the molecular mechanisms involved. CFM-1, -4, and -5 inhibited MPM cell growth, in vitro, in part by stimulating apoptosis. Apoptosis by CFM-4 involved activation of …

School of Medicine Faculty Publications

Kaposi's sarcoma-associated herpesvirus is the causative agent of primary effusion lymphoma (PEL), which arises preferentially in the setting of infection with human immunodeficiency virus (HIV). Even with standard cytotoxic chemotherapy, PEL continues to cause high mortality rates, requiring the development of novel therapeutic strategies. PEL xenograft models employing immunodeficient mice have been used to study the in vivo effects of a variety of therapeutic approaches. However, it remains unclear whether these xenograft models entirely reflect clinical presentations of KSHV(+) PEL, especially given the recent description of extracavitary solid tumor variants arising in patients. In addition, effusion and solid tumor cells …

Journal of Patient-Centered Research and Reviews

The development and regulatory approval of vemurafenib and dabrafenib for metastatic melanoma patients with activating BRAF mutations has demonstrated that personalized targeted therapy strategies can provide significant clinical benefit in this highly aggressive disease. However, these agents are not beneficial in patients who do not have activating BRAF mutations, representing over half of all melanoma patients. Recent studies have demonstrated that melanomas have the highest rate of somatic mutations among the major cancers. Based on this information, additional personalized treatment strategies are now in various stages of clinical development and testing. These efforts are being guided by the lessons learned …

Sentinel Lymph Node Biopsy In Head And Neck Melanoma: A Review, Martin Corsten, Stephanie Johnson-Obaseki

Journal of Patient-Centered Research and Reviews

The incidence of melanoma in the United States continues to rise. Head and neck melanomas comprise approximately 20% of all primary cutaneous melanomas. Sentinel lymph node (SLN) biopsy (SLNB) has become the standard of care for staging in melanoma. It has a number of advantages, including the addition of prognostic information, accurate staging, and the potential to add completion lymph node dissection (CLND) or adjuvant therapy when indicated. Furthermore, it may allow for the identification of patients who would benefit from inclusion in clinical trials; this advantage may be amplified based on the introduction of novel targeted therapies.
