The Dietary Inflammatory Index and Human Health: An Umbrella Review of Meta-Analyses of Observational Studies.

Adv Nutr 2021 Apr 19. Epub 2021 Apr 19.

Deakin University, Institute for Mental and Physical Health and Clinical Translation (IMPACT), Food & Mood Centre, School of Medicine, Barwon Health, Geelong, Victoria, Australia.

Numerous observational studies have investigated the role of the Dietary Inflammatory Index (DII®) in chronic disease risk. The aims of this umbrella review and integrated meta-analyses were to systematically synthesize the observational evidence reporting on the associations between the DII and health outcomes based on meta-analyses, and to assess the quality and strength of the evidence for each associated outcome. This umbrella review with integrated meta-analyses investigated the association between the DII and a range of health outcomes based on meta-analyses of observational data. Read More

Pre-diagnosis alcohol intake and metachronous cancer risk in cancer survivors: a prospective cohort study.

Int J Cancer 2021 Apr 19. Epub 2021 Apr 19.

Cancer Epidemiology Division, Cancer Council Victoria, 615 St Kilda Road, Melbourne, Victoria, Australia.

Alcohol consumption is a known cause of cancer, but its role in the etiology of second primary (metachronous) cancer is uncertain. Associations between alcohol intake up until study enrollment (pre-diagnosis) and risk of metachronous cancer were examined in 9,435 participants in the Melbourne Collaborative Cohort Study who were diagnosed with their first invasive cancer after enrollment (1990-94). Follow-up was from date of first invasive cancer until diagnosis of metachronous cancer, death or censor date (February 2018), whichever came first. Read More

Multistage Rectal Polypectomy: An Alternative to Proctectomy in Patients with Familial Adenomatous Polyposis.

Dis Colon Rectum 2021 Apr 13. Epub 2021 Apr 13.

Sanford R. Weiss M.D. Center for Hereditary Colorectal Neoplasia, Cleveland Clinic Foundation, Cleveland, Ohio.

Introduction: When patients with familial adenomatous polyposis have a severely affected rectum it is usually assumed that endoscopic control is impossible or unwise. The standard approach is proctectomy with either an end ileostomy, or an ileal pouch anal anastomosis. Here we show that application of aggressive, multistage snare polypectomy to this situation can be effective and allow the patient to avoid surgery, at least in the short term. Read More

High-throughput microscopy reveals the impact of multifactorial environmental perturbations on colorectal cancer cell growth.

Gigascience 2021 Apr;10(4)

Lawrence J. Ellison Institute for Transformative Medicine, University of Southern California, Los Angeles, CA 90064, USA.

Background: Colorectal cancer (CRC) mortality is principally due to metastatic disease, with the most frequent organ of metastasis being the liver. Biochemical and mechanical factors residing in the tumor microenvironment are considered to play a pivotal role in metastatic growth and response to therapy. However, it is difficult to study the tumor microenvironment systematically owing to a lack of fully controlled model systems that can be investigated in rigorous detail. Read More

Mutated DNA Damage Repair Pathways Are Prognostic and Chemosensitivity Markers for Resected Colorectal Cancer Liver Metastases.

Front Oncol 2021 31;11:643375. Epub 2021 Mar 31.

Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), Hepatopancreatobiliary Surgery Department I, Peking University Cancer Hospital, Beijing, China.

Deficiency of the DNA damage repair (DDR) signaling pathways is potentially responsible for genetic instability and oncogenesis in tumors, including colorectal cancer. However, the correlations of mutated DDR signaling pathways to the prognosis of colorectal cancer liver metastasis (CRLM) after resection and other clinical applications have not been fully investigated. Here, to test the potential correlation of mutated DDR pathways with survival and pre-operative chemotherapy responses, tumor tissues from 146 patients with CRLM were collected for next-generation sequencing with a 620-gene panel, including 68 genes in 7 DDR pathways, and clinical data were collected accordingly.

PeerJ 2021 5;9:e11219. Epub 2021 Apr 5.

The First Clinical Medical College, Lanzhou University, Lanzhou, Gansu, China.

Colorectal cancer (CRC) is one of the most prevalent and fatal malignancies, and novel biomarkers for the diagnosis and prognosis of CRC must be identified. RNA-binding proteins (RBPs) are essential modulators of transcription and translation. They are frequently dysregulated in various cancers and are related to tumorigenesis and development. Read More

PeerJ 2021 7;9:e10851. Epub 2021 Apr 7.

Department of Medicine, Therapeutic Protein Engineering Lab, College of Medicine, Chung-Ang University, Seoul, South Korea.

Immunization with thetumor-associated antigen GA733 glycoprotein, which is highly expressed in colorectal cancer, is considered to be a promising strategy for cancer prevention and treatment. We cloned a fusion gene of GA733 and immunoglobulin Fc fragment (GA733-Fc), and that of GA733-Fc and an endoplasmic reticulum retention motif (GA733-FcK) into the Cowpea mosaic virus (CPMV)-based transient plant expression vector, pEAQ-. (LBA4404) transformed with the vectors pEAQ--GA733-Fc and pEAQ--GA733-FcK was infiltrated into the leaves of plants. Read More

License to kill: microsatellite instability and immune contexture.

Oncoimmunology 2021 Apr 2;10(1):1905935. Epub 2021 Apr 2.

Laboratory of Integrative Cancer Immunology, INSERM, Paris, France.

Colorectal cancers (CRCs) with microsatellite instability (MSI) are due to a defect in the DNA mismatch repair (MMR) system resulting in an accumulation of frame-shift mutations. They are characterized by a tumor microenvironment richer in cytotoxic CD8 T-cells (CTLs) and a better prognosis compared to microsatellite stable (MSS) CRCs. The mechanisms by which defective MMR system may influence tumor-infiltrating immune cells and their impact on patient survival were still unclear. Read More

Impact of EGFR and EGFR ligand expression on treatment response in patients with metastatic colorectal cancer.

Oncol Lett 2021 Jun 7;21(6):448. Epub 2021 Apr 7.

Department of General, Visceral and Transplantation Surgery, University of Heidelberg, D-69120 Heidelberg, Germany.

Up to 50% of patients with colorectal cancer (CRC) have either synchronous or metachronous hepatic metastases in the course of their disease. Patients with metastatic CRC (mCRC) whose tumors express wild-type KRAS benefit from treatment with monoclonal antibodies (such as cetuximab or panitumumab) that target the epidermal growth factor receptor (EGFR). However, the therapeutic response to these antibodies is variable, and further predictive models are required. Read More

Characterization and clinical evaluation of microsatellite instability and loss of heterozygosity in tumor-related genes in gastric cancer.

Oncol Lett 2021 Jun 30;21(6):430. Epub 2021 Mar 30.

School of Basic Medical Sciences, Capital Medical University, Beijing 100069, P.R. China.

Microsatellite instability (MSI) detection is widely used in the diagnosis and prognosis evaluation of colorectal cancer. However, for gastric cancer (GC), there is no standard panel of microsatellites (MSs) used in clinical guidance. The present study aimed to identify useful predictors of the clinical features and for the prognosis of GC, based on an investigation of MSI and loss of heterozygosity (LOH) in tumor-related genes.
