The study covered in this summary was published on ResearchSquare.com as a preprint and has not yet been peer reviewed.

Key Takeaway

  • This study reported that patients with visceral adiposity, including patients with diabetes and metabolic syndrome, were found to have high incidence of colorectal cancer and colorectal adenoma compared with a control group of patients without neoplastic disease.

Why This Matters

  • The study provides insight on potential physical exam and laboratory predictors of colorectal cancer.

  • These metabolism-related routine laboratory tests and anthropometric measurements may be used to screen high-risk patients for colorectal cancer to promote early detection and treatment.

Study Design

  • This retrospective, case-control study selected a cohort of 80 patients with colorectal cancer, 80 patients with colorectal adenoma, and 80 patients with non-neoplastic disease from one nursing unit between April 2017 and April 2019. Patients with non-neoplastic disease were matched to patients with colorectal cancer on the basis of sex and age.

  • Exclusion criteria included a history of cancer, incomplete colonoscopy, inflammatory bowel disease, history of familial adenomatous polyposis syndrome, evident edema, seroperitoneum, and incomplete data.

  • Waist, hip, and neck circumferences were measured using bony anatomy structures.

  • Laboratory measures of hemoglobin, albumin, and plasma glucose and lipid profile were collected by standard methods after overnight fasting.

Key Results

  • The study reported a higher prevalence of diabetes (P = .016) among patients with colorectal cancer compared with patients without neoplastic disease.

  • Patients with diabetes, metabolic syndrome, and high waist-to-neck ratio were found to have a high incidence of colorectal cancer and colorectal adenoma.

  • Metabolic syndrome, high waist-to-neck ratio (odds ratio [OR], 2.795), and high waist-to-height ratio (OR, 3.009) were associated with an increased risk for colorectal cancer in male patients.

  • In female patients, only high waist-to-hip ratio was found to be a high-risk factor (multivariable adjusted OR, 3.354).

  • Anemia, hypoproteinemia, and self-reported weight loss were associated with a higher incidence of colorectal cancer compared with colorectal adenoma.

Limitations

  • Selection bias may be present owing to the retrospective design of the study.

  • The study was a single-center study with a small number of patients with colorectal cancer; thus, results will need to be further evaluated in multiple-center research.

  • Only hospitalized individuals were included in this study, and so results cannot be generalized to a social normal population.

Disclosures

  • The study was supported by the Exceptional Young Talents Fostering Foundation 2021 of the Tianjin Fourth Central Hospital (tjdszxyy20210013).

  • The authors declared no competing interests.
