Background The use of combined chemotherapy and radiation for gastrointestinal malignancies has several theoretical advantages, and clinical trials to determine the type and extent of clinical benefits have been performed. Methods The basic science and clinical trial data evaluating such combinations are reviewed, with an emphasis on the interactions between fluoropyrimidines and radiation. Results Improved outcomes from chemoradiotherapy have been demonstrated in patients with selected stages of anal, esophageal, rectal, and pancreatic cancer. Conclusion Despite these positive results, further work is needed to demonstrate even more effective and less toxic treatment regimens.

Assessment And Treatment

Background: The most common liver diseases are fibrosis, alcoholic liver disease, non-alcoholic fatty disease, viral hepatitis, and hepatocellular carcinoma. These liver diseases account for approximately 2 million deaths per year worldwide, with cirrhosis accounting for 2.1% of the worldwide burden. The most widely used liver function tests for diagnosis are alanine transaminase, aspartate transaminase, serum proteins, serum albumin, and serum globulins, whereas antivirals and corticosteroids have been proven to be useful for the treatment of liver diseases. A major disadvantage of these diagnostic measures is the lack of specificity to a particular tissue or cell type, as these enzymes are common to one or more tissues. The major adverse effect of current treatment methods is drug resistance. To overcome these issues, interleukins have been investigated. The balance of these interleukins determines the outcome of an immune response. Interleukins are considered interesting therapeutic targets for the treatment of liver diseases. In this review, we summarize the current state of knowledge regarding interleukins in the diagnosis, treatment, and pathogenesis of different acute and chronic liver diseases. Objective: To understand the role of interleukins in the assessment and treatment of different types of liver diseases. Methods: A literature search was conducted using PubMed, Science Direct, and NCBI with the following keywords: Interleukins, Acute Liver Failure, Alcoholic Liver Disease, Non-Alcoholic Fatty Liver Disease, Liver Fibrosis, Hepatocellular Carcinoma, Inflammation, Liver injury, Hepatoprotective effect. Clinical trial data on these interleukins have been searched on Clinicaltrials.gov. Results: Existing literature and preclinical and clinical trial data demonstrate that interleukins play a crucial role in the pathogenesis of liver diseases. Conclusion: Our findings indicate that IL-1, IL-6, IL-10, IL-17, IL-22, IL-35, and IL-37 are involved in the progression and control of various liver conditions via the regulation of cell signaling pathways. However, further investigation on the involvement of these interleukins is necessary for their use as a targeted therapy in liver diseases.

The Impact

479 Background: Gastrointestinal (GI) cancers are a heterogeneous group of cancers with varying underlying pathophysiology and distinct treatment paradigms. Immunotherapy (IO) is unique in each of the subtypes and biomarkers utility varies. With the expansion of IO in each cancer subtypes, education remains essential to optimize patient outcomes through integration of the latest evidence-based data at point of care. Through the partnership between Medscape Oncology and the Society for Immunotherapy of Cancer, 2 educational activities were designed to increase the knowledge and competence of oncologists surrounding the role of IO in patients with advanced GI cancers. Methods: The 2 educational activities included a text based online activity with 3 chapters focused on gastroesophageal cancers, colorectal cancers, and hepatocellular carcinoma (HCC) and a 30-minute online, video discussion with 3 faculty and synchronized slides on HCC. Educational effectiveness was assessed with repeated paired pre/post assessment where learners served as their own controls. A chi-square test was used to identify statistical significance in proportion of correct responses. The first activity launched 11/27/2019 and the second activity launched on 5/8/20. Data were collected and reported through 8/25/2020. Results: A total of 8433 learners, including 1543 oncologists, participated from 11/2019 through 8/2020. Participation in education resulted in significant relative improvements among oncologist learners on IO in GI cancers in (n = 641): 110%: role or eligibility of immune checkpoint inhibitors (ICIs) (p < .001) 38%: clinical trial data of ICIs (p < .001) Subsequent education on unresectable HCC demonstrated a significant relative improvement in both knowledge and competence for oncologist learners (n = 902): 19%: regarding clinical trial data in unresectable HCC (p = .073) 19%; competence identifying role of ICIs in unresectable HCC (p < .05) 59%: competence managing irAEs in unresectable HCC (p < .001). Conclusions: These 2 online CME-certified educational activities resulted in statistically significant gains in oncologist knowledge surrounding the use of IO in advanced GI cancers Follow-up education on HCC demonstrated the value and benefit of multi-modal and sequential activities on improving competence among oncologists caring for patients with unresectable HCC There remains a need for continuous education as more oncologists utilize IO in their practice while the understanding and availability of clinical data continues to expand and evolve in the varying GI cancer subtypes. More than 50% of learners continued to demonstrate a need in understanding the clinical trial data or role of IO in metastatic GI cancers with more than 40% of the learners demonstrating continued need on clinical trial data or role of IO in HCC specifically.

SummaryThe important role of the P2Y12 receptor in amplification of platelet activation and associated responses and the limitations associated with clopidogrel therapy have led to the development of novel inhibitors of this receptor. Three reversibly-binding P2Y12 inhibitors are in phase 3 development, ticagrelor, cangrelor and elinogrel. The pharmacology and clinical trial data for each of these inhibitors are discussed and compared with relevant data for the thienopyridines clopidogrel and prasugrel.

Increasing evidence supports the important role of nutrition in cancer prevention, including prevention of prostate cancer. In this review, we summarize data for some of the most consistently observed dietary associations for prostate cancer incidence, briefly consider possible postdiagnostic effects of nutrition on prostate cancer progression/survival, discuss new but limited data on diet-gene interactions, and comment on current areas of controversy for future research focus. Potential protective dietary elements include tomatoes/lycopene, other carotenoids, cruciferous vegetables, vitamin E, selenium, fish/marine omega-3 fatty acids, soy, isoflavones and polyphenols; whereas milk, dairy, calcium, zinc at high doses, saturated fat, grilled meats, and heterocyclic amines may increase risk. It is important to note that randomized clinical trial data exist only for vitamin E, calcium, beta-carotene, and selenium (all of which suggest inverse or no association). Several genes, such as MnSOD, XRCC1, and GST, may modify the association of specific nutrients and foods with prostate cancer risk; and further research is warranted to confirm these initial observed relationships. Until further clinical trial data are available on specific supplements and prostate cancer prevention, it would be prudent to emphasize a diet consisting of a wide variety of plant-based foods and fish; this is similar to what is recommended (and what is more well established) for the primary prevention of heart disease.

Technical Features

Background:Data management is an important, complex and multidimensional process in clinical trials. The execution of this process is very difficult and expensive without the use of information technology. A clinical data management system is software that is vastly used for managing the data generated in clinical trials. The objective of this study was to review the technical features of clinical trial data management systems.Methods:Related articles were identified by searching databases, such as Web of Science, Scopus, Science Direct, ProQuest, Ovid and PubMed. All of the research papers related to clinical data management systems which were published between 2007 and 2017 (n=19) were included in the study.Results:Most of the clinical data management systems were web-based systems developed based on the needs of a specific clinical trial in the shortest possible time. The SQL Server and MySQL databases were used in the development of the systems. These systems did not fully support the process of clinical data management. In addition, most of the systems lacked flexibility and extensibility for system development.Conclusion:It seems that most of the systems used in the research centers were weak in terms of supporting the process of data management and managing clinical trial's workflow. Therefore, more attention should be paid to design a more complete, usable, and high quality data management system for clinical trials. More studies are suggested to identify the features of the successful systems used in clinical trials.
