The prevalence of colorectal cancer (CRC) is on a steady rise over the years, with the World Health Organization (WHO) reporting CRC as the fourth leading cause of cancer-related death worldwide. While treatment modalities may differ in accordance to the staging and severity of the disease itself, chemotherapy is almost unavoidable in most cases. Though effective in its mode of action, chemotherapy is commonly associated with undesirable side effects that negatively affects the patient in terms of quality of life, and in some cases may actually interfere with their treatment regimens, thus escalating to poor prognosis...

Polymethoxylated flavones (PMFs) have been recognized to inhibit colorectal cancer proliferation through various mechanisms, however most of these studies have been performed on cells grown as monolayers that present limitations in mimicking the 3D tumor architecture and microenvironment. The main aim of this study was to investigate the anticancer potential of an orange peel extract (OPE) enriched in PMFs in a 3D cell model of colorectal cancer. The OPE was developed by supercritical fluid extraction and the anticancer effect was evaluated in HT29 spheroids cultures in a stirred-tank based system...

The association between a Western Diet and colon cancer suggests that dietary factors and/or obesity may contribute to cancer progression. Our objective was to develop a new animal model of obesity and the associated pathophysiology to investigate human cancer independent of dietary components that induce obesity. A novel congenic rat strain was established by introducing the fa allele from the Zucker rat into the Rowett Nude rat to generate a "fatty nude rat". The obese phenotype was first characterized in the new model...

Breast cancer survivors often seek information about how lifestyle factors, such as diet, may influence their prognosis. Previous studies have reviewed evidence around single nutrients, individual foods or food groups. We reviewed studies examining relationships between overall dietary intake and prognosis in breast cancer survivors. A systematic search was conducted to identify studies, published until June 2016, which assessed associations between overall dietary intake (i.e., quality; score; pattern) and mortality and/or recurrence in breast cancer survivors...

Oral cancer is a common malignancy in both men and women worldwide; this cancer is characterized by a marked propensity for invasion and spreading to local lymph nodes. On the other hand, Elaeagnus angustifolia (EA) is a medicinal plant that has been used for centuries for treating many human diseases in the Middle East. However, the effect of EA plant extract on human cancers especially oral has not been investigated yet. Thus, first we examined the outcome of EA flower extract on angiogenesis, using the chorioallantoic membrane (CAM) of the chicken embryo; we found that EA extract reduces blood vessel development of the CAM...

Melanoma is the most deadly form of skin cancer, with about 48,000 deaths each year worldwide. Growing evidence suggests that individual nutrients or dietary patterns might have important roles in the prevention of melanoma. Considering that melanoma is a potentially life-threatening cancer, novel protective and adjuvant treatments are needed to improve its prognosis. Curcumin is a bioactive substance extracted from rhizome of Curcuma longa L. Its global market is expected to grow in the next few years, especially in the pharmaceutical industry, due to its numerous physiological and pharmacological properties...

We hypothesized that synergy between curcumin (CURC), trastuzumab (TZMB), and glutathione peroxidase-1 (GPX-1) accelerates breast cancer (BC) cell apoptosis which is inhibited by glial cell line-derived neurotrophic factor (GDNF). We measured survival of BC cell lines treated or cotreated with CURC and TZMB, and then with GDNF, before measuring expression levels of growth and apoptosis genes. These experiments were also repeated on SKBR3 cells transiently expressing GPX-1. CURC+TZMB cotreatment induced BC cell apoptosis more significantly than single treatment...

Observational studies on the association between fish and poultry intake and the risk of total cancer mortality have been reported with mixed results. Thus, we aimed to assess this association by conducting a meta-analysis of prospective studies. We performed a literature search on PubMed database through February 1, 2017 to identify relative prospective studies. A random-effects model was used to calculate the summary estimates. We identified fourteen prospective studies involving 2,378,204 participants and 96,712 cancer mortality events...

The aim of this study was to evaluate whether digestive tract mucositis is a predictive factor for body weight (BW) alterations during hematopoietic stem cell transplantation (HSCT). Data about characteristics of transplantation, initial nutritional conditions and gastrointestinal mucositis were collected from adult patients (n = 105) who underwent autologous and allogeneic HSCT. Oral mucositis (OM) was not a predictive factor for BW loss, but it was an independent factor for BW gain in autologous HSCT (β = 0...

Inconsistent results from epidemiologic studies of circulating fatty acids and prostate cancer risk may be partly due to use of blood concentrations as surrogate biomarkers of prostate tissue concentrations. To determine whether blood concentrations reflect prostate tissue fatty acid profiles, we evaluated associations between phospholipid fatty acid (PLFA) profiles measured in plasma and prostate tissue from 20 patients who underwent prostatectomy. For each patient, three prostate tissue specimens varying in size and location were collected...

Dietary phenolic compounds are plant metabolites with beneficial effects on the central nervous system. Thus, our aim was to identify anti-inflammatory compounds from South American plants on glia, which regulates neuro-immune response. The compounds were extracted from Lantana grisebachii (LG), Aspidosperma quebracho-blanco (AQB), and Ilex paraguariensis (IP) teas and identified by HPLC-DAD-MS. Extracts (0-200 µg/ml) were tested on human T98-G and rat C6 glioma lines. Cellular viability (by the resazurin assay), fatty acid profile (by gas chromatography) and pro-inflammatory interleukin-6 release (IL-6 by ELISA) were determined...

Patients with esophageal cancer are at high risk of developing malnutrition during neoadjuvant chemoradiation therapy (CRT), which in turn is associated with postoperative morbidity. The aim of the study is to explore whether parameters of a complete pre-treatment nutritional status may predict deterioration of nutritional status during CRT in patients with esophageal cancer. In this prospective cohort study, 101 patients with esophageal cancer treated with CRT were included. Data of patient characteristics, tumor classification, performance score, %weight change, body mass index, fat (free) mass index, phase angle, handgrip strength, energy- and protein intake, and use of (additional) dietary supplements were collected...

Systemic cytotoxic chemotherapy remains the mainstay of metastatic breast cancer; however, prognosis and overall survival is unfavorable due to inadequate treatment response and/or unacceptable toxicity. Natural compounds and their active metabolites receive increasing attention as possible adjuvant therapy with cancer chemotherapeutics to improve treatment response, survival rates, and quality of life of breast cancer patients. This study investigated the combination of flaxseed lignans (Secoisolariciresinol and Enterolactone) with classic chemotherapeutic agents (Docetaxel, Doxorubicin, and Carboplatin) with different mechanisms of action to determine whether flaxseed lignans could enhance the cytotoxic effect of such drugs in the metastatic breast cancer cell lines, SKBR3 and MDA-MB-231...
