Abstract
Gut bacteria might contribute in early stage of colorectal cancer through the development and advancement of colon adenoma, by which exploring either beneficial bacteria, which are decreased in formation or advancement of colon adenoma and harmful bacteria, which are increased in advancement of colon adenoma may result in implementation of dietary interventions or probiotic therapies to functional means for prevention. Korean fermented kimchi is one of representative probiotic food providing beneficiary microbiota and exerting significant inhibitory outcomes in both APC/Min+ polyposis model and colitis-associated cancer. Based on these backgrounds, we performed clinical trial to document the changes of fecal microbiota in 32 volunteers with normal colon, simple adenoma, and advanced colon adenoma with 10 weeks of fermented kimchi intake. Each amplicon is sequenced on MiSeq of Illumina and the sequence reads were clustered into Operational Taxonomic Units using VSEARCH and the Chao Indices, an estimator of richness of taxa per individual, were estimated to measure the diversity of each sample. Though significant difference in α or β diversity was not seen between three groups, kimchi intake significantly led to significant diversity of fecal microbiome. After genus analysis, Acinobacteria, Cyanobacteria, Clostridium sensu, Turicibacter, Gastronaeophillales, H. pittma were proven to be increased in patients with advanced colon adenoma, whereas Enterococcua Roseburia, Coryobacteriaceau, Bifidobacterium spp., and Akkermansia were proven to be significantly decreased in feces from patients with advanced colon adenoma after kimchi intake. Conclusively, fermented kimchi plentiful of beneficiary microbiota can afford significant inhibition of either formation or advancement of colon adenoma.

Abstract
BACKGROUND AND OBJECTIVES Colonoscopy is the gold standard for detection of polyps and is preventive against colorectal cancers. Flat adenomas are small, superficial lesions and have a high rate of going undetected during conventional white-light endoscopy. This article adds to the scant body of literature in English regarding in vivo detection and diagnosis of flat adenomas using Fujinon intelligent color enhancement (FICE) system. In this study, we investigated the diagnosis of flat lesions via the FICE endoscopy system and in vivo histologic diagnostic estimations of flat lesions. METHODS This prospective study was conducted in patients who underwent colonoscopy that found flat adenomas. Lesions were classified morphologically with regard to the Paris Classification and sent for histopathologic examination after in vivo histologic diagnostic estimations were made according to Kudo's pit pattern classification. The positive predictive value (PPV), negative predictive value (NPV), specificity, sensitivity, and accuracy of in vivo endoscopic diagnostic estimations of flat lesions with the FICE system were analyzed. RESULTS A total of 217 flat lesions were identified in 137 patients. Of the lesions, 85.7% were Paris type 0-IIa, and 59.4% were Kudo pit pattern type III. When the FICE diagnostic estimations of flat lesions and final pathology results were considered, PPV was 68.5%, NPV value was 89.6%, sensitivity was 94.7%, specificity was 50.9%, and accuracy was 74.2%. CONCLUSIONS Biologic importance of flat lesions is obscure, as they are usually missed during colonoscopy. The use of novel endoscopic techniques may improve their detection and diagnosis rates.

Abstract
BACKGROUND The aim of this study was to identify stage II colon cancer patients with a high risk of recurrence. METHODS All patients who underwent surgery for stage II colon cancer (CC) were retrospectively enrolled and sub-grouped according to TNM staging (IIa-b-c) and stage IIa in high (IIaHR) and low risk (IIaLR) according to pathologic features. The primary outcomes measured were the 5-year overall survival (OS) and disease-free survival (DFS). RESULTS A total of 214 patients were reviewed. Only a maximum tumor diameter<4 cm in the IIaLR group was associated with a higher recurrence rate than a large tumor size (5-year DFS 71.7%vs.87.6%, p = 0.028). The DFS in the large IIaLR CC group was better than that in the IIaHR and IIb-c groups (5-year DFS: 92.7%vs.79.3%, p = 0.023). In contrast, the recurrence rate in the small IIaLR CC group was similar to that in the IIaHR, IIb-c stage CC group. CONCLUSIONS In stage IIa CC evaluation of the tumor size as a prognostic factor may help identify patients who could benefit from additional postoperative therapy.

Abstract
Colorectal cancer screening is useful not only in detecting colorectal cancer at an early stage, but also in finding people with precancerous conditions. Proper interference in precancerous patients is good for reducing the occurrence of cancer. The precancerous conditions vary from patient to patient, so is the risk of malignant transformation. However, the lack of clear definition and classification for precancerous colorectal conditions in China makes standard treatment and follow-up management of these people difficult. This review summarizes basic definition and classification for precancerous colorectal conditions, clarifies different risks among people, and introduces the latest progress in follow-up intervals worldwide.

Abstract
The mainstream carcinogenic processes involved within the gastrointestinal tract are characterized by phenotypic multistep progression cascades that eventually result in full-blown cancers. In this scenario, the understanding of the molecular dysregulations underlying the precancerous lesions is increasing but still remains incomplete. However, in recent years, the enthusiastic rise of innovative technologies (i.e., next-generation sequencing, high-throughput microarray analysis, mass spectrometry based proteomics) and the unexpected discovery of new classes of biomarkers (i.e., miRNA, long-noncoding RNAs) prompted new strength in the exploration of the accurate and comprehensive molecular characterization of premalignant and malignant neoplastic lesions. The challenge ahead lies in the reliable identification of disease progression-specific targets to enable molecular testing in the clinical management of the secondary prevention of gastrointestinal cancers.
