Novel parameter based on lipid indicators ratio improves prognostic value of plasma lipid levels in resectable colorectal cancer patients.

Background: At present, the value of lipid indicators in evaluating the prognosis of colorectal cancer is still relatively limited.

Aim: To evaluate the value of a novel parameter for colorectal cancer (CRC) prognosis scoring based on preoperative serum lipid levels.

Methods: Four key serum lipid factors, namely, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB), were detected.

Clinicopathological Features and Prognostic Value of KRAS/NRAS/BRAF Mutations in Colorectal Cancer Patients of Central China.

The incidence of colorectal cancer (CRC) is increasing in China, with high mortality. Here, we aimed to evaluate the latest clinicopathological features and prognostic value of the KRAS/NRAS/BRAF mutation status in CRC patients in Central China. The clinical data of 1549 CRC patients with stage I-IV disease diagnosed at Union Hospital, Tongji Medical College of Huazhong University of Science and Technology from 2015 to 2017 were collected and analyzed retrospectively.

The prognostic value of AGR2 expression in solid tumours: a systematic review and meta-analysis.

The prognostic value of anterior gradient-2 (AGR2) in tumours remains inconclusive. Here, we systematically reviewed the literature evidence and assessed the association between AGR2 expression and prognosis in solid tumours. The primary outcomes were overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS)/recurrence-free survival (RFS)/progression-free survival (PFS).

Clinicopathologic features and prognosis of primary gastrointestinal stromal tumor patients under 35 years of age: A 10-year retrospective study.

Objectives: To investigate gastrointestinal stromal tumor (GIST) clinicopathologic characteristics in young adults.

Methods: Clinicopathologic data from GIST patients under 35 years diagnosed at our hospital from January 2005 to December 2014 were retrospectively collected.

Results: Thirty-one (5.

Anatomical basis and clinical research of pelvic autonomic nerve preservation with laparoscopic radical resection for rectal cancer.

The clinical effect of laparoscopic rectal cancer curative excision with pelvic autonomic nerve preservation (PANP) was investigated. This study evaluated the frequency of urinary and sexual dysfunction of 149 male patients with middle and low rectal cancer who underwent laparoscopic or open total mesorectal excision with pelvic autonomic nerve preservation (PANP) from March 2011 to March 2013. Eighty-four patients were subjected to laparoscopic surgery, and 65 to open surgery respectively.

The Diagnostic Performance of Stool DNA Testing for Colorectal Cancer: A Systematic Review and Meta-Analysis.

This meta-analysis was designed to evaluate the diagnostic performance of stool DNA testing for colorectal cancer (CRC) and compare the performance between single-gene and multiple-gene tests.MEDLINE, Cochrane, EMBASE databases were searched using keywords colorectal cancers, stool/fecal, sensitivity, specificity, DNA, and screening. Sensitivity analysis, quality assessments, and performance bias were performed for the included studies.

Estrogen inhibits colon polyp formation by reducing angiogenesis in a carcinogen-induced rat model.

Objective. To study the effects of estrogen on colon polyp formation, proliferation, and angiogenesis on a rat model of colon cancer induced by dimethylhydrazine (DMH). Methods.

Transcriptional inactivation of ERbeta gene is mediated by the induction of promoter hypermethylation in a rat colonic epithelial cell model.

Background: To construct a primary rat colonic epithelial cell model for treatment with specific methylated oligonucleotides (MOs) and to determine whether the transcriptional inactivation of ERbeta mRNA is mediated by the induction of hypermethylation of the ERbeta gene promoter.

Methods: Suckling rat colonic epithelial cells were cultured in DMEM. Two methylated oligonucleotides complementary to the promoter regions of ERbeta were synthesized and applied to the cultured cells to induce promoter hypermethylation of the ERbeta gene.

Effects of carbon dioxide and nitrogen on adhesive growth and expressions of E-cadherin and VEGF of human colon cancer cell CCL-228.

Aim: To study the effects of carbon dioxide on the metastatic capability of cancer cells, and to compare them with that of nitrogen.

Methods: The colon cancer cell CCL-228 was treated with 100 % carbon dioxide or nitrogen at different time points and then cultured under normal condition. Twelve hours after the treatment, the survival rates of suspension cells and the expressions of e-cadherin and VEGF were examined.
