Inflammation plays a central role in pancreatic cancer etiology and can be modulated by diet. We aimed to examine the association between the inflammatory potential of diet, assessed with the Dietary Inflammatory Index (DII®), and pancreatic cancer risk in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial prospective cohort. Our study included 101,449 participants aged 52 to 78 years at baseline who completed both baseline questionnaire and a diet history questionnaire. Energy-adjusted DII (E-DII) scores were computed based on food and supplement intake...

Human peritoneal mesothelial cells belong to a narrow group of somatic cells in which both the triggers and the mechanisms of senescence have already been well defined. Importantly, senescent mesothelial cells have been found in the peritoneal cavity in vivo. From a clinical point of view, peritoneal mesothelial cells have been recognized as playing a critical role in the intraperitoneal development of tumor metastases. The pro-cancerogenic behavior of mesothelial cells is even more pronounced when the cells exhaust their proliferative capacity and become senescent...

Chaperone-mediated autophagy (CMA) characterized by the selective degradation of target proteins has been linked with tumorigenesis in recent years. Here, we explored the function of sorting nexin 10 (SNX10), a protein involved in maintaining endosome/lysosome homeostasis, in mediating CMA activity and its impact on the progression of mouse colorectal cancer. Our results revealed that SNX10 deficiency increased the activation of CMA by preventing the degradation of lysosomal LAMP-2A. In SNX10 KO cells, we disclosed that p21Cip1/WAF1, a master effector in various tumor suppressor pathways, is a substrate of CMA, and decrease of p21Cip1/WAF1 caused by SNX10-mediated CMA activation contributes to HCT116 cell proliferation and survival...

The encroachment of a growing tumor upon the cells and structures of surrounding normal tissue results in a series of histopathological growth patterns (HGPs). These morphological changes can be assessed in hematoxylin-and-eosin (H&E) stained tissue sections from primary and metastatic tumors and have been characterized in a range of tissue types including liver, lung, lymph node and skin. HGPs in different tissues share certain general characteristics like the extent of angiogenesis, but also appropriate tissue-specific mechanisms which ultimately determine differences in the biology of HGP subtypes...

Ureterosigmoidostomy has largely been disregarded in recent times but has now seen a resurgence of interest because of its potential applicability to newer, minimally-invasive surgical techniques. The advantages of ureterosigmoidostomy over intestinal conduits are urinary continence (obviating the need for stoma and external appliances), ease and rapidity of performance as well as acceptance by patients. Ureterosigmoidostomy has been characterized by good continence outcomes and it offers good quality of life...

miRNAs are small regulatory RNA molecules involved in posttranscriptional gene silencing. Their biosynthesis results in the formation of duplex consisting of a leading and a passenger strand of mature miRNA. The leading strand exhibits the main activity but recent findings indicate a certain role of the passenger strand as well. Deregulated levels of miRNA were found in many types of cancers including colorectal cancer. miR-21 and miR-16 were indicated as possible markers of colorectal cancer, however, small attention to gender differences in their expression was paid so far...

We have successfully demonstrated that host-guest complex of carboxylated pillar[6]arene with oxaliplatin exhibits low cytotoxicity toward normal cells and displays higher anticancer bioactivity against colorectal cancer cells than oxaliplatin itself. Owing to higher binding affinity of carboxylated pillar[6]arene with spermine than that of with oxaliplatin, the oxaliplatin can be thoroughly released from its host-guest complex by the competitive replacement with spermine. This supramolecular chemotherapy works well both in vitro and in vivo for spermine-overexpressed cancers, such as colorectal cancer...

OBJECTIVE: To investigate the clinicopathological features and prognosis of colorectal synchronous multiple primary cancer(SMPC). METHODS: From January 2008 to June 2011, 51 patients diagnosed with colorectal SMPC underwent surgery at Department of General Surgery of Peking University First Hospital. Their clinicopathological features, diagnosis, treatment and prognosis were summarized and analyzed. SMPC was diagnosed according to the following criteria: each tumor must have a definite pathologic picture of malignancy; metastasis or recurrence from another colorectal cancer was excluded; tumors must be distinctly separated by at least 5 cm of all intact bowel wall from each other; SMPC has abnormal cells between tumor and normal mucosa and abnormal gland of transitional zone; each cancer is infiltrating carcinoma except the carcinoma in situ; all the cancers are detected at the same time or within 6 months...

Radical surgeries and(neo) adjuvant therapies have significantly prolonged survival of patients with colorectal cancer. Microinvasive surgery and function preservation become more important with the prerequisite of R0 resection. As for colorectal cancer, long term survival after laparoscopic curative surgery is proved non-inferior to its open counterpart. The new transanal approach of total mesorectal excision, while avoiding abdominal incision for extraction, may as well improve surgical quality. Local excision and the "watch and wait" strategy, though attractive for organ-preservation, are undermined by suboptimal clinical and radiographic assessment of lymph node and treatment response, respectively...

1) to evaluate efficiencies of gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) for preoperative assessment of liver metastases from colorectal carcinoma, and 2) to compare them with other diagnostic imaging modalities. The subjects of the analysis were outpatients with advanced colorectal cancer who are at risk of developing liver metastases (initial setting: pre-test probability=20%). At initial setting, we performed a decision analysis to calculate numbers of true positive (TP), false negative (FN), false positive (FP) and true negative (TN) test results per 1000 patients of Gd-EOB-MRI and other imaging modalities (conventional contrast agent-enhanced MRI, contrast-enhanced CT and 18F-FDG PET/CT)...
