Background: Altered lipid metabolism is a hallmark of cancer development. However, the role of specific lipid metabolites in colorectal cancer development is uncertain.
Methods: In a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), we examined associations between pre-diagnostic circulating concentrations of 97 lipid metabolites (acylcarnitines, glycerophospholipids and sphingolipids) and colorectal cancer risk. Circulating lipids were measured using targeted mass spectrometry in 1591 incident colorectal cancer cases (55% women) and 1591 matched controls. Multivariable conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between concentrations of individual lipid metabolites and metabolite patterns with colorectal cancer risk.
Findings: Of the 97 assayed lipids, 24 were inversely associated (nominally p < 0.05) with colorectal cancer risk. Hydroxysphingomyelin (SM (OH)) C22:2 (OR 0.60, 95% CI 0.47-0.77) and acylakyl-phosphatidylcholine (PC ae) C34:3 (OR 0.71, 95% CI 0.59-0.87) remained associated after multiple comparisons correction. These associations were unaltered after excluding the first 5 years of follow-up after blood collection and were consistent according to sex, age at diagnosis, BMI, and colorectal subsite. Two lipid patterns, one including 26 phosphatidylcholines and all sphingolipids, and another 30 phosphatidylcholines, were weakly inversely associated with colorectal cancer.
Interpretation: Elevated pre-diagnostic circulating levels of SM (OH) C22:2 and PC ae C34:3 and lipid patterns including phosphatidylcholines and sphingolipids were associated with lower colorectal cancer risk. This study may provide insight into potential links between specific lipids and colorectal cancer development. Additional prospective studies are needed to validate the observed associations.

Increased adiposity and chronic psychosocial stress (CPS) are plausible modifiable contributors of the recent increase in early-onset colorectal cancer (EOCRC). We conducted an 8-week randomized controlled pilot trial evaluating the feasibility and acceptability of time restricted eating (TRE) (daily ad libitum eating between 12-8pm) and Mindfulness ("Mindfulness for Beginners" course from the Calm app) among young adults. Participants were randomized to the following groups: TRE ( = 10); Mindfulness ( = 11); TRE & Mindfulness ( = 11); or Control ( = 11).

Importance: Patients with advanced cancer frequently receive broad-spectrum antibiotics, but changing use patterns across the end-of-life trajectory remain poorly understood.
Objective: To describe the patterns of broad-spectrum antibiotic use across defined end-of-life intervals in patients with advanced cancer.
Design, Setting, And Participants: This nationwide, population-based, retrospective cohort study used data from the South Korean National Health Insurance Service database to examine broad-spectrum antibiotic use among patients with advanced cancer who died between July 1, 2002, and December 31, 2021.

To evaluate the expression of hsa_circ_0077007 in the serum of colorectal cancer (CRC) patients and offer a foundational theory for the prognosis of CRC. The present study focuses on investigating the biological function and therapeutic target of hsa_circ_0077007 in colorectal cancer CRC. Retrieve the GEO database and use the GEO2R tool to analyze the GSE dataset (GSE223001 and GSE159669) to obtain aberrantly expressed circRNAs.

Colorectal cancer (CRC) is one of the most common and lethal malignancies worldwide, with treatment failure often attributed to chemoresistance and evasion of apoptosis. Cathayanon E (CE), a natural chalcone derivative isolated from Morus alba, has shown anticancer potential, but its role and mechanism in CRC remain largely unexplored. In this study, CE significantly inhibited CRC cell proliferation and induced apoptosis both in vitro and in vivo.
