Objective: To review the worldwide studies on natural history models among colorectal cancer (CRC), and to inform building a Chinese population-specific CRC model and developing a platform for further evaluation of CRC screening and other interventions in population in China. Methods: A structured literature search process was conducted in PubMed and the target publication dates were from January 1995 to December 2014. Information about classification systems on both colorectal cancer and precancer on corresponding transition rate, were extracted and summarized...

Transmembrane C-X-C chemokine receptor 4 (CXCR4) and its ligand C-X-C motif chemokine 12 (CXCL12) came into focus in many solid cancers, allowing a more fundamental diagnostic and therapeutic approach by modulating the immune response against cancer cells. CXCR4 and CXCL12 mediate cell proliferation, migration, and metastatic outgrowth in head and neck squamous cell carcinoma (HNSCC) and are strongly associated with cancer recurrence and patient survival. Despite recent advances in molecular imaging and cancer therapy in lymphoma using CXCL12 analogues, clinical trials evaluating the diagnostic and therapeutic impact on HNSCC are missing...

Thyroid cancer derived from follicular cells (TCDFC) comprises well-differentiated (papillary and follicular) carcinoma, poorly differentiated carcinoma, and anaplastic carcinoma. Papillary thyroid carcinoma is the most common endocrine cancer, and its incidence is steadily increasing. Lethality and aggressiveness of TCDFC is inversely correlated with differentiation degree. In this review, an emphasis has been put on molecular markers involved in tumorigenesis of thyroid carcinoma with a focus on aggressive histotypes and the role of such biomarkers in predicting thyroid cancer outcome...

PURPOSE: We examined the expression, clinical correlation and functional mechanisms of endogenous microRNA-424 (miR-424) in human non-small cell lung cancer (NSCLC). METHODS: Expression pattern of endogenous miR-424 was examined by qRT-PCR in clinical samples obtained from 233 NSCLC patients. Correlations between differential miR-424 expression level (low vs. high) and NSCLC patients' clinicopathological parameters or survival were statistically examined. In in vitro NSCLC H596 and SW900 cells, miR-424 was either upregulated or downregulation by lentiviral transduction...

PURPOSE OF REVIEW: The purpose of this review is to recapture recent advances in cachexia-related diseases, mainly cancer cachexia, and treatment using genomic, transcriptomics, proteomic, and metabolomics-related techniques. RECENT FINDINGS: From recent studies in the cancer cachexia field it is clear that the tumor has a direct effect on distant organs via its secretome. The affected pathways on the other hand were largely known from earlier studies with changes in energy-related pathways (mainly lipid metabolism) and the protein degradation pathways...

Glioblastoma Multiforme (GBM) is a highly malignant primary brain cancer that is associated with abysmal prognosis. The median survival of GBM patients is ∼15 months and there have not been any significant advance in therapies in over a decade, leaving treatment options limited. There is clearly an unmet need for GBM treatment. Immunotherapies are treatments based on usurping the power of the host's immune system to recognize and eliminate cancer cells. They have recently proven to be a successful strategy for combating a variety of cancers...

Beans, peas, and lentils are all types of pulses that are extensively used as foods around the world due to their beneficial effects on human health including their low glycemic index, cholesterol lowering effects, ability to decrease the risk of heart diseases and their protective effects against some cancers. These health benefits are a result of their components such as bioactive proteins, dietary fibers, slowly digested starches, minerals and vitamins, and bioactive compounds. Among these bioactive compounds, γ-aminobutyric acid (GABA), a non-proteinogenic amino acid with numerous reported health benefits (e...

BACKGROUND: Current data on the utility of port-site excision (PSE) during re-resection for incidentally discovered gallbladder cancer (IGBC) in the US are conflicting and limited to single-institution series. METHODS: All patients with IGBC who underwent curative re-resection at 10 institutions from 2000 to 2015 were included. Patients with and without PSE were compared. Primary outcome was overall survival (OS). RESULTS: Of 449 pts with GBC, 266 were incidentally discovered, of which 193(73%) underwent curative re-resection and had port-site data; 47 pts(24%) underwent PSE, 146(76%) did not...

REVIEW
Kaixian Zhang, Qianqian Yuan
Lung cancer continues to be a major health problem and the most common cancer-related mortality worldwide with about 80%-85% patients suffering from nonsmall cell lung cancer (NSCLC). More than 80% of NSCLC cases are often diagnosed as advanced stage and harbor epidermal growth factor receptor (EGFR) activating mutation. Although great success in initial response to EGFR-tyrosine kinase inhibitors (EGFR-TKIs) are found in EGFR-mutant NSCLC patients, acquired resistance usually occurs on the continuous treatment...

INTRODUCTION: Pain is a common symptom experienced by cancer patients, especially in those with advanced disease. Our aim was to describe pain intensity in advanced cancer patients, referred to the palliative care unit, the factors underlying moderate to severe pain and its prognostic values. MATERIAL AND METHODS: This was a prospective observational study. All patients with mestastatic solid tumors and with no specific oncologic treatment were included. Pain intensity was accessed using the pain scale from Edmonton Symptom Assessment Scale, rated from 0 to 10 on a numerical scale, where zero = no pain and 10 = worst possible pain...

REVIEW

Prostate cancer is the second leading cause of cancer deaths in the USA. The challenge in managing castration-resistant prostate cancer (CRPC) stems not from the lack of therapeutic options but from the limited duration of clinical and survival benefit offered by treatments in this setting due to primary and acquired resistance. The remarkable molecular heterogeneity and tumor adaptability in advanced prostate cancer necessitate optimization of such treatment strategies. While the future of CRPC management will involve newer targeted therapies in deliberately biomarker-selected patients, interventions using current approaches may exhibit improved clinical benefit if employed in the context of optimal sequencing and combinations...

Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall, usually forming an abnormally long common channel. In PBM, since the long common channel defeats the effect of the sphincter of Oddi, pancreatobiliary reflux frequently occurs, resulting in high rates of biliary tract cancers. We present the case of a 68-year-old female with advanced gallbladder cancer concomitant with bile duct cancer associated with PBM without biliary dilatation that had an extremely rare configuration showing a connecting duct without a long common channel...

BACKGROUND: Cholangiocarcinoma (CCA) is the second most common primary liver cancer, being characterized by its late diagnosis and fatal outcome. Recent epidemiological reports indicate an increasing worldwide incidence of intrahepatic CCA but a decreasing incidence of extrahepatic CCA. METHODS: In this review, we present an overview of the incidence and epidemiology of CCA and possible strategies for screening and surveillance. RESULTS: Efficient strategies for the screening and surveillance of CCA have not been established so far...

BACKGROUND: The aim of this pilot study was to measure changes in physical activity level (PAL) variables, as well as sleep duration and efficiency in people with locally advanced rectal cancer (1) before and after neoadjuvant chemoradiotherapy (CRT) and (2) after participating in a pre-operative 6-week in-hospital exercise training programme, following neoadjuvant CRT prior to major surgery, compared to a usual care control group. METHODS: We prospectively studied 39 consecutive participants (27 males)...

BACKGROUND: Neuroendocrine carcinoma is an uncommon histology for breast cancer. CASE REPORT: Our patient underwent right quadrantectomy for a neuroendocrine carcinoma in 1984 and had a bone relapse 30 years later. After thorough pathological and immunohistochemical analysis the diagnosis was confirmed and HER2 amplification was observed. Here we discuss the management, rationale and results of HER2-targeted therapy in advanced neuroendocrine breast carcinoma.
