Radiation induced fibrosis (RIF) is a common morbidity in patients being treated for cancer with radiation. Off-target effects result in intense inflammatory responses which ultimately results in the generation of extracellular matrix (ECM) producing myofibroblasts which mediate a progressive fibrosis resulting in scarring and organ and tissue dysfunction. Unfortunately, currently, there are no effective therapies to block the excess accumulation of ECM. We have previously reported on the use of trametinib, a MEK inhibitor, to essentially block the formation of abdominal adhesions in a mouse model of cecal abrasion. Using this drug in the mouse model, the complete trans-differentiation of precursor cells into ECM-producing myofibroblasts was blocked. Trametinib is a potentially powerful drug to thwart organ and tissue fibrosis in RIF because it has a potential dual function in that it may block RIF as well as prevent radiation-resistance. Given the intractability of RIF, trametinib should be considered for more extensive testing.

Breast cancer remains the second leading cause of cancer death among women and is the most commonly diagnosed cancer in women. Breast cancer risk assessment has been clinically available for nearly 30 years yet is under-utilized in practice for multiple reasons. Incorporation of polygenic risk as well as breast density measurements, promise to increase the accuracy of risk assessment. With that comes the hope that both prevention and screening become more personalized and thus more effective. Incidence rates have been static over the past 15 years and have even increased slightly in African American and Asian/Pacific Islander populations despite the robust data on breast cancer risk reduction measures that exist. Current challenges in reducing breast cancer incidence begin with robust data curation that allows for appropriate risk stratification across our multiethnic population and conclude with the implementation of prevention strategies within our fractured healthcare system.

Endocrine tumors of chromaffin cells are most frequent in the gastrointestinal tract. Moreover, they are the ones of best prognosis. Promising results have been recorded for liver transplantations in case of metastatic gastrointestinal neuroendocrine tumors. We exhibit a case report of a patient presenting dyspeptic and carcinoid syndrome, hepatic metastasis diagnosis and primary tumor of the ileum detected through scheduled hepatectomy. Liver transplantation was the chosen therapy given the impossibility of hepatectomy due to hepatic metastatic involvement. Liver transplantation is a healing therapeutic option for patients with gastrointestinal neuroendocrine tumor in case of unresectable hepatic metastases. It assures more than 50% survival within 5 years in case of primary tumors in the small intestine. Survival is longer in case of liver transplantation after primary tumor resection than in usual palliative treatments such as embolization and chemoembolization.

The article points out the importance of the therapeutic management of the neuroendocrine gastrointestinal metastatic tumor, with emphasis on performing liver transplantation as a possible curative treatment.

Introduction: Several studies have provided important information about health conditions and other challenges faced by women diagnosed with breast cancer and how they can improve their quality of life and reduce their risk of cancer recurrence. Although African American and Hispanic breast cancer patients have a poorer survival than their white counterparts, few studies have compared the experiences of African American, Hispanic, and non-Hispanic white breast cancer survivors.

Objectives: To facilitate collaborative studies on breast cancer survivorship in a multicultural population, including future intervention research on nutrition, and physical activity, and clinical substudies.

Methods: This cohort study consists of a postal survey of up to 1,000 women with a history of a breast cancer diagnosis who reside in Augusta-Richmond County, Georgia, USA, and a repeat survey in 4 to 5 years to obtain longitudinal data. The follow-up survey in 4 to 5 years will allow for longitudinal changes in health to be assessed.

Conclusion: The survey will provide a comprehensive picture of the health of breast cancer survivors, across the lifespan, in a large Southern city. A broad range of health issues will be addressed including physical activity, diet, nutrition, personal and family history of cancer, quality-of-life, psychosocial concerns, and beliefs about cancer recurrence risk reduction through lifestyle changes. Through its longitudinal design, the study will also provide important information about changes in physical and mental health as breast cancer survivors advance in age.

Many types of cancers require elevated levels of Reactive Oxygen Species (ROS) for uncontrolled proliferation. However, this also makes tumor cells more susceptible to ROS induced cell death by additional oxidative stress caused by external stimuli. By selectively targeting cancer cells and tumors that exhibit high levels of ROS with nanotechnology-based materials to trigger further elevation of ROS therapeutic possibilities become available. Specifically, light-activated treatment through Photodynamic Therapy (PDT) has been demonstrated as a feasible approach with Photophryn as the leading FDA approved sensitizer. However, such small molecule sensitizers do still have significant hurdles to overcome, including poor solubility, non-targeted delivery, and low absorption of light. In this mini review, recent advances in the development of Conjugated Polymer Nanoparticles (CP-NPs) solving these issues are discussed, including amplified ROS generation, tumor targeting, theranostic capabilities, and multimodal CP-NPs. We also give an outlook towards further needs in CP-NP development for clinical application.

Osteosarcoma is a rare but deadly cancer, predominantly affecting both adolescent and young adult populations. Osteosarcoma occurs when an aggressive malignant neoplasm arises from transformed cells of mesenchymal origin, which eventually produce a malignancy in the osteoid. Diagnosis of osteosarcoma typically results from symptoms of pain or swelling in the bone, which can be confirmed through laboratory testing of alkaline phosphatase and lactate dehydrogenase levels as well the detection of microscopic and macroscopic lesions. Pathogenesis of osteosarcoma is caused by a diverse set of factors including physical agents, radiation, chromosomal aberrations and viral infection which dysregulate cellular functions. Current research focuses on understanding how microRNAs play a role in osteosarcoma and other aggressive cancers. In this review, we discuss current treatments options including chemoresistant strategies and immunotherapies that show promise at combating osteosarcoma and other cancers.

Screening mammography is recommended by U.S. medical organizations for breast cancer screening in average risk women because of its demonstrated reductions in breast cancer mortality. However, significant disparities in breast cancer screening utilization and mortality remain among racial/ethnic minorities. Efforts have appropriately been directed at increasing engagement with screening services in these populations, however, there is a dearth of data regarding false-positive rates and overdiagnosis in minority patients engaged in breast cancer screening. We recently examined screening practices among a predominantly Hispanic population presenting to an academic medical center in New York, NY, and found that approximately 53% of women experienced at least one false-positive mammography result over a median of 8.9 years of screening. We also observed that Hispanic women were more likely to screen annually than white women despite recommendations to screen less frequently. In this review, we briefly review the benefits and harms of screening mammography in average-risk women, namely, false-positive results and breast cancer overdiagnosis, followed by a discussion of the disparities in breast cancer screening and mortality among racial/ethnic minority populations. We then present our own recent observations and propose that future interventions among Hispanic and other minority populations could include patient- and provider-centered educational programs that focus on providing a balanced discussion of benefits and harms of screening mammography.

With high morbidity and mortality, lung cancer has become the leading cause of cancer-related death worldwide, of which 85% are non-small-cell lung cancer (NSCLC). Most patients present with advanced disease at diagnosis and 5-year survival rate is no more than 30% due to lack of appropriate screening and early detection. In spite of tissue samples, ctDNA (circulating tumor DNA) is also widely used for molecular profiling to guide the treatment of NSCLC for lots of advantages. This review mainly focuses on the clinical and investigational applications of ctDNA detection in facilitating the personalized therapy of NSCLC.

Initially reported by Mandel et al. in 1948M1, cfDNA (cell-free DNA) refers to the acellular, free DNA fragments in circulation (plasma or serum) derived from somatic cells through mechanisms like necrosis, apoptosis and exosome secretion. ctDNA is cfDNA generated by tumor cells, which carries cancer-associated genetic alterations2,3. In 1977, Leon et al. first reported that the level of plasma ctDNA of patients with cancer was significantly higher than that of normal persons4, which was also confirmed in NSCLC5,6. In NSCLC patients, techniques for targetable genetic ctDNA detection have improved from traditional ARMS, HPLC, BEAMing, FISH to new generations of NGS (next generation sequencing), ddPCR and CAPP-Seq etc. Compared with traditional detection methods, NGS shows extraordinary advantages like massively parallel sequencing, lower-inputs, cost-effectivity, ultra-sensitivity and hyper accuracy7,8. The main applications of ctDNA detection in the personalized treatment of NSCLC patients will be discussed in this review.

Concurrent chemoradiotherapy plays a vital role in the treatment of locally advanced squamous cell carcinoma of the oropharynx (LA-OPC). Importantly, only 50-85% of patients undergoing this treatment are able to complete their prescribed chemotherapy courses due to treatment-associated morbidity. The significance of chemotherapy completion, or lack thereof, remains unknown in this setting. To further investigate if chemotherapy non-completion affects patient outcomes, a single institutional retrospective study was undertaken analyzing 73 patients undergoing definitive radiation for LA-OPC and revealed a near-significant trend toward improved overall survival on multivariable analysis (p=0.053) in those completing chemotherapy. We are presently providing a commentary on this manuscript in an attempt to provide context and further interpretation of the presented results as well as suggest areas in need of additional investigation.

Head and neck cancer (HNC) carry a high level of morbidity and mortality, but the impact of HNC on survivors differs widely among individuals, and a significant number of them suffer from negative psychological effects of the disease. However, some people report a significant positive effect of experiencing HNC and its treatment.

This review looks at demographic, clinical and psychological factors associated with positive psychological change (PPC) in HNC populations.

Eight quantitative manuscripts were identified as reporting on PPC in HNC. These studies were split between recruiting participants via cancer clinics and postal surveys, and the majority use a cross-sectional study design.

Demographic factors across the papers showed similar patterns of relationships across PPC; that higher education/qualification and cohabitation/marriage are associated with increased PPC. Limited research reported longitudinal patterns of change and showed that for people with lower stage tumours and those who only had a surgical intervention greater PPC developed over time. Multivariable modeling adjusting for psychosocial variables found that PPC had a quadratic relationship with time since diagnosis, increasing initially and leveling off after 18 months.

Further research would aid the identification of bio-psychosocial factors that influence the development of PPC and inform the development of rehabilitation interventions while enabling consideration of the natural development of the phenomenon.

Evasion of apoptosis is one of the typical hallmarks of cancer and a major mechanism for cancer development, tumor growth, and acquisition of resistance to chemotherapy. The anti-apoptotic Bcl-2 protein family, particularly MCL1 and BCL-XL, play an important role in acquisition of apoptosis evasion. MCL1 is a highly unstable protein that is constantly degraded by the ubiquitin-proteasome system. An increase in MCL1 protein has been reported in many cancers, including lung cancer, through high mRNA expression or impairment of its degradation systems. To date, much evidence has shown that MCL1 is important for cancer cell survival and drug resistance in lung cancers. In this review, we discuss the role and mechanism of high MCL1 expression in lung cancer.

Multiplexed immunofluorescence (IF) methods to detect simultaneously different molecules are revolutionizing immunohistochemistry (IHC) in the last years. These new technologies can be valuable for tumor examination in formalin-fixed paraffin-embedded (FFPE) specimens, and for improved new treatment discoveries and translational cancer studies. The aim of this mini-review is to highlight the recent methodologies that using multiplexed IF to study simultaneous proteins identification in FFPE tumor tissues to clinical research and potential translational analysis. Multiplexed IF methods, which permit the identification of up to 4 proteins at the same time, have been increased in the last years the abilities of study cells by cells and their spatial distribution in several tumor tissues. Although, most of the old platforms are not more used after the powerful multiplex IHC methods are continue growing, the basis of these old methodologies have helped to improve the new technologies. Associated with image analysis software’s these technologies can be improved to performance high throughput assay to study these specimens. Each multiplexed IF technique, detailed herein, is associated with important advantages in cancer study as well as translational research studies.

Lung cancer being one of the leading causes of cancer-related deaths around the world has significantly added to the global burden of disease. Late diagnosis, unavailability of definitive treatment and an unclear pathophysiological mechanism behind the role of various genes expressed in lung cancer make it a challenge that needs new techniques and better understanding of the underlying pathology and role of genetics. Long non coding RNAs, once considered insignificant, are now being elucidated to have major roles to play in the regulation and development of carcinogenesis. In this review, the ability of a lncRNA, lncRNA IGFBP4-1 to modulate cellular metabolic processes, eventually affecting lung cancer progression and consequently being a potential biomarker for lung cancer diagnosis has been discussed.

Regulatory CD4+T-cells have been recently classified as regulatory T helper (Th)-like cells according to the expression of specific transcription factors, cytokines and chemokine receptors that mirror effector Th lineages. In our report: “An Atlas of Human Regulatory T Helper-like Cells Reveals Features of Th2-like Tregs that Support a Tumorigenic Environment” we found that Th2-like Tregs were increased in the tumour microenvironment in comparison with Th1-like, Th17-like and Th1/Th17-like Tregs. In addition, despite similar expression of CCR4 between all Tregs subtypes, Th2-like Tregs migrated more toward CCL17 and CCL22, and expressed higher levels of CCR8 than the other Th-like Tregs. Other studies have characterised human tissue-infiltrating Tregs and demonstrated that CCR8 is the main chemokine receptor differentially expressed in Tregs isolated from malignant tissues in comparison with healthy tissues. Given that CCR8 is a marker of Th2 lineages it is possible that Th2-like Tregs and CCR8+ Tregs are the same population of cells involved in tumour progression. However, whether they are recruited or differentiated in situ by the tumour microenvironment is still unknown. In this mini review, we describe the role of the different Th subsets in health and cancer and we present the different hypotheses about the presence of Th2-like Tregs in the tumorigenic environments.

Cancer arises through the accumulation of genetic and epigenetic alterations. Comprehensive analyses of human cancer epigenomes over the past decade have revealed that chromatin and epigenetic aberrations induced by genetic, metabolic, and environmental stimuli play important roles in tumor initiation as well as progression. Among these aberrations, DNA hypermethylation at promoter regions is one of the major mechanisms to silence tumor suppressor genes in cancer, and has been studied in detail. For gastric cancer, for example, we and other groups have conducted genome-wide DNA methylation analyses, and classified gastric cancer into several DNA methylation epigenotypes. Gastric cancer with Epstein-Barr virus (EBV) infection exhibits the most extensive hypermethylation phenotype among all the human malignancies, and EBV infection itself is shown to cause aberrant DNA methylation induction. EBV infection also alters histone modifications, not only at promoter regions but also at enhancer regions. Epigenetic alteration at enhancers causes aberrant regulation of cancer-related genes together with epigenetic alteration at promoters, and it is known to contribute to tumorigenesis. We here review epigenetic aberration at enhancer regions in gastric cancer.

Prostate cancer (PCa) incidence is increasing due to the ageing worldwide population. In recent years, the unsuitability of prostate specific antigen (PSA) as a diagnostic biomarker has become apparent. Unnecessary treatment of men with non-lethal disease leading to significant quality-of-life reducing side-effects resulted in 2017 in the US Preventative Services Task Force (USPSTF) recommending selective and limited use of PSA testing for PCa. An immediate need exists for a test capable of accurate and early diagnosis of PCa. Critically, this test must differentiate between indolent and aggressive PCa to inform appropriate management of the disease. The key to predictive accuracy is the utilisation of combinations of diverse biomarkers and clinical data. A number of suitable new tests have emerged since 2013 but none of these have been implemented in the clinical setting. Extensive clinical validation of these tests is critical to address the chasm that now exists in PCa diagnostics. This mini review assesses current clinical issues for PCa diagnosis, evaluates currently available commercial tests and critically assesses next-generation diagnostic tools that could revolutionise PCa diagnostics.

The major theme throughout this paper was solving the problem of multidrug resistance (MDR) in chemotherapeutic remediation for breast cancer patients by an aptamer-labeled hybrid nanoparticle to enhance selective delivery of siRNA into tumor cells and produce an enhanced knock-down of P-glycoprotein (P-gp); which was detected mainly by western blot. The primary focus of this study was to know whether labeling nanoparticles with a cancer cell specific aptamer could enhance selective delivery of siRNA into tumor cells leading to enhanced knock-down of P-glycoprotein or P-gp as compared to non-labeled nanoparticles. The goal is to minimize cancerous gene expression by silencing its mRNA. Target specificity is not only key in completing this goal, but it is also necessary regarding, biodegradability, cytotoxicity and immune response. To accomplish this goal, the design methods had to be meticulous and carefully researched andapplied.

Pancreatic ductal adenocarcinoma (PDAC) is the fourth most lethal tumor around the world and stands out from many other cancers. Despite increasing research for better diagnostic and treatment strategies, there has hardly been a substantial improvement over the last decades in the 5-year survival. This is mainly because, at the time of diagnosis, the cancer cells have already migrated and invaded distant organs and tissues. At this stage, patients in most cases are ineligible for surgery and their response to conventional therapies, such as radiotherapy and chemotherapy, is also very poor.

Researchers have mainly been targeting the genetic alterations of the cancer cells, and these genetic therapies in pancreatic cancer have significantly failed to improve patient survival. It is true that the early stages of tumor formation are based on a combination of genetic and epigenetic alterations that activate oncogenes and/or inhibit tumor suppressor genes, but progress in PDAC is mainly orchestrated by microenvironmental factors. Recently, targeting tumor microenvironment components that play a prominent role in tumor progression (fibrous tissue, angiogenesis, hypoxia, tumor-associated macrophages, etc.) have begun to attract the focus of cancer researchers. In addition, immunotherapy, which has shown some success in other types of cancer, is now also emerging for pancreatic cancer for which the microenvironment possess specific challenges.

This review highlights current obstacles and opportunities in pancreatic cancer research and treatment (in vitro and in vivo (patient-derived tumor xenografts and genetic engineered mouse models)) and also indicates future directions to be explored as a potential strategy to improve patient outcomes.

The first clinical trials subdued optimistic forecasts of the rapid use of iPSC technology across a large spectrum of diseases. However, positive safety results originating from administration of differentiated ESCs to first patients can be treated as the promise to future of this regenerative medicine branch. Advances in non-viral methods for pluripotency induction, including episomal and mRNA strategies as well as microRNA switches robustly purifying heterogeneous differentiated PSCs may accelerate further progress. In the present decade the development of an effective genome editing including CRISPR/Cas9, novel therapeutic approach and intensive research in 3D in vitro culture systems including tissue engineering can further expand the potential of iPSCs. The herein mini-review article extends and updates the current approaches in state-of-the-art techniques of human embryonic stem cell and induced pluripotent stem cell derivation.
