Abstract
While monoclonal antibody-based targeted therapies have substantially improved progression-free survival in cancer patients, the variability in individual responses poses a significant challenge in patient care. Therefore, identifying cancer subtypes and their associated biomarkers is required for assigning effective treatment. In this study, we integrated genotype and pre-treatment tissue RNA-seq data and identified biomarkers causally associated with the overall survival (OS) of colorectal cancer (CRC) patients treated with either cetuximab or bevacizumab. We performed enrichment analysis for specific consensus molecular subtypes (CMS) of colorectal cancer and evaluated differential expression of identified genes using paired tumor and normal tissue from an external cohort. In addition, we replicated the causal effect of these genes on OS using validation cohort and assessed their association with the Cancer Genome Atlas Program data as an external cohort. One of the replicated findings was WDR62, whose overexpression shortened OS of patients treated with cetuximab. Enrichment of its over expression in CMS1 and low expression in CMS4 suggests that patients with CMS4 subtype may drive greater benefit from cetuximab. In summary, this study highlights the importance of integrating different omics data for identifying promising biomarkers specific to a treatment or a cancer subtype.

Cancer Metab 2023; 11:15. [PMID: 37705114 PMCID: PMC10500936 DOI: 10.1186/s40170-023-00315-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 08/22/2023] [Indexed: 09/15/2023] Open
Abstract
Hypercholesterolemia is often correlated with obesity which is considered a risk factor for various cancers. With the growing population of hypercholesterolemic individuals, there is a need to understand the role of increased circulatory cholesterol or dietary cholesterol intake towards cancer etiology and pathology. Recently, abnormality in the blood cholesterol level of colon cancer patients has been reported. In the present study, we demonstrate that alteration in cholesterol levels (through a high-cholesterol or high-fat diet) increases the incidence of chemical carcinogen-induced colon polyp occurrence and tumor progression in mice. At the cellular level, low-density lipoprotein cholesterol (LDLc) and high-density lipoprotein cholesterol (HDLc) promote colon cancer cell proliferation by tuning the cellular glucose and lipid metabolism. Mechanistically, supplementation of LDLc or HDLc promotes cellular glucose uptake, and utilization, thereby, causing an increase in lactate production by colon cancer cells. Moreover, LDLc or HDLc upregulates aerobic glycolysis, causing an increase in total ATP production through glycolysis, and a decrease in ATP generation by OXPHOS. Interestingly, the shift in the metabolic status towards a more glycolytic phenotype upon the availability of cholesterol supports rapid cell proliferation. Additionally, an alteration in the expression of the molecules involved in cholesterol uptake along with the increase in lipid and cholesterol accumulation was observed in cells supplemented with LDLc or HDLc. These results indicate that colon cancer cells directly utilize the cholesterol associated with LDLc or HDLc. Moreover, targeting glucose metabolism through LDH inhibitor (oxamate) drastically abrogates the cellular proliferation induced by LDLc or HDLc. Collectively, we illustrate the vital role of cholesterol in regulating the cellular glucose and lipid metabolism of cancer cells and its direct effect on the colon tumorigenesis.

Abstract
A high-fat diet plays a key role in the pathogenesis of colorectal cancer, and this effect on the gut can also occur in the offspring of mothers with a high-fat diet. In this review, we discuss the role of a high-fat diet in the pathogenesis of colorectal cancer and summarize the effects of a maternal high-fat diet on the activation of inflammation and development of colorectal cancer in offspring. Studies have found that a maternal high-fat diet primarily induces an inflammatory response in the colorectal tissue of both the mother herself and the offspring during pregnancy. This leads to the accumulation of inflammatory cells in the colorectal tissue and the release of inflammatory cytokines, which further activate the NF-κb and related inflammatory signaling pathways. Research suggests that high levels of lipids and inflammatory factors from mothers with a high-fat diet are passed to the offspring through the transplacental route, which induces colorectal inflammation, impairs the intestinal microecological structure and the intestinal barrier, and interferes with intestinal development in the offspring. This in turn activates the NF-κb and related signaling pathways, which further aggravates intestinal inflammation. This process of continuous inflammatory stimulation and repair may promote the uncontrolled proliferation of colorectal mucosal cells in the offspring, thus increasing their susceptibility to colorectal cancer.

Abstract
OBJECTIVE To analyze the gastrointestinal function and prognostic value of tumor markers (TMs) in patients with laparoscopic radical resection of colorectal cancer (LRRCC). METHODS The research population of this retrospective study comprised 141 patients with CC who received treatment in the Zhongshan Hospital of Xiamen University between July 2017 and August 2018, including 74 cases (observation group, OG) treated with LRRCC and 67 cases (control group, CG) undergoing open surgery (OS). Postoperative gastrointestinal function and complications were recorded. Besides, alterations in serum TMs carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), and the 3-years survival of patients were observed. Receiver operating characteristic (ROC) curves were used to determine the prognostic value of TMs. Risk factors affecting the prognosis of LRRCC patients were analyzed by the Cox regression model. RESULTS Significantly higher levels of motilin (MOT) and gastrin (GT) were determined in OG compared with CG. The two groups showed no notable difference in the postoperative complication rate. Postoperative serum CEA and CA199 levels were obviously lower in OG as compared with CG. A higher 3-year survival rate was determined in OG. The areas under the receiver operating characteristic (ROC) curve (AUCs) of CEA and CA19-9 levels in predicting patients' 3-year survival were 0.826 and 0.867, respectively. According to the Cox regression analysis, tumor diameter, lymph node involvement, TNM staging, vascular invasion, CEA, and CA19-9 were independent risk factors for poor prognosis of LRRCC patients. CONCLUSIONS LRRCC is well-tolerated by patients with CC and contributes to favorable outcomes. Besides, CEA and CA19-9, the two TMs, may be candidate prognostic markers for patients undergoing LRRCC.

High levels of triglycerides, apolipoprotein B, and the number of colorectal polyps are risk factors for colorectal polyp recurrence after endoscopic resection: a retrospective study. J Gastrointest Oncol 2022; 13:1753-1760. [PMID: 36092331 PMCID: PMC9459209 DOI: 10.21037/jgo-22-491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 07/12/2022] [Indexed: 11/06/2022] Open
Abstract
Background The recurrence of polyps after endoscopic treatment is a difficult problem and there may be an association between blood lipid levels and colorectal polyps, but this is controversial and the aim of this study is to explore the risk factors for colorectal polyp recurrence. Methods A total of 357 patients who underwent intestinal polypectomy from January 1, 2019 to June 1, 2020 in Sichuan Provincial People's Hospital were included in this retrospective study to analyze the potential association between blood indices and recurrence risk. Polyp recurrence was defined as the detection of 1 or more polyps at any time after polypectomy, regardless of site. Follow-up was performed through the electronic medical record system. Patients' age, gender, tobacco and alcohol liking, duration of follow-up, body mass index (BMI), polyp size, number, type of pathology, and lipid profiles (triglycerides, cholesterol, apolipoprotein B, and apolipoprotein A) were collected. Results Triglycerides (1.54±0.95 vs. 1.25±1.01, P=0.036) and apolipoprotein B (0.87±0.26 vs. 0.79±0.16 mL, P=0.001) were significantly different in both the recurrence and non-recurrence groups. Binary logistic regression identified 3 independent risk factors for recurrence: triglycerides [odds ratio (OR): 1.763, 95% confidence interval (CI): 1.003 to 3.098, P=0.049], apolipoprotein B (OR: 5.438, 95% CI: 1.411 to 20.961, P=0.014), and the number of polyps (OR: 2.540, 95% CI: 1.649 to 3.911, P<0.001). Conclusions High levels of triglycerides, apolipoprotein B, and the number of colorectal polyps are risk factors for colorectal polyp recurrence after endoscopic resection. Therefore, for patients at high risk of polyp recurrence, we recommend aggressive control of triglyceride and apolipoprotein B levels.

Dyslipidaemia Is Associated with Severe Disease Activity and Poor Prognosis in Ulcerative Colitis: A Retrospective Cohort Study in China. Nutrients 2022; 14:nu14153040. [PMID: 35893893 PMCID: PMC9330762 DOI: 10.3390/nu14153040] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 07/21/2022] [Accepted: 07/21/2022] [Indexed: 01/27/2023] Open
Abstract
Background: Clinical data on the correlation of dyslipidaemia with the long-term outcomes of ulcerative colitis (UC) are limited. This study aimed to evaluate the impact of lipid levels on disease activity and prognosis in UC. Methods: The retrospective data of UC patients who had detailed lipid profiles were collected from January 2003 to September 2020. All patients were followed-up to 30 September 2021. The long-term outcomes were UC-related surgery and tumorigenesis. Results: In total, 497 patients were included in the analysis. Compared to patients with normal lipid levels, those with dyslipidaemia commonly presented with more serious disease activity. Low high-density lipoprotein cholesterol (p < 0.05) levels were associated with higher risks of severe disease activity in UC. Regarding the long-term outcomes, patients with persistent dyslipidaemia were at higher risks of UC-related surgery (HR: 3.27, 95% CI: 1.86−5.75, p < 0.001) and tumorigenesis (HR: 7.92, 95% CI: 3.97−15.78, p < 0.001) and had shorter surgery- and tumour-free survival (p < 0.001) than patients with transient dyslipidaemia and normal lipid levels. Low levels of high-density lipoprotein cholesterol (p < 0.001) and apolipoprotein A1 (p < 0.05) were associated with higher risks of surgery and tumorigenesis. Conclusion: Persistent dyslipidaemia was associated with a higher risk of serious disease activity and worse long-term outcomes among patients with UC. Lipid patterns should be assessed to improve the management of high-risk patients with UC in the early phase.
