OBJECTIVE: Given that the onset of diseases including colorectal cancer precursors is affecting younger individuals and that obesity is an important risk factor for early-onset, we conducted a study to explore the biochemical profile of differences in serum between early-onset patients and late-onset colorectal precancerous lesions.
METHODS: A total of 1447 patients, including 469 early-onset patients and 978 late-onset patients, were enrolled from the First Affiliated Hospital of Nanchang University (FAHNU), of which there were 311 sessile serrated adenoma/polyps (SSA/P) and 1136 normal adenomas. The distribution of the included categorical variables was compared via Pearson's chi-squared test, whereas continuous variables were compared by using the nonparametric Kruskal-Wallis test and ANOVA.
RESULTS: Compared with late-onset patients, the levels of total bilirubin and HDL-C were lower (p < 0.05), whereas triglyceride and uric acid levels were higher, in early-onset patients. Interestingly, in the subgroup analysis, triglyceride and uric acid levels remained at higher levels, whereas HDL-C remained at lower levels, in early-onset patients than in late-onset patients. Other characteristics, such as LDL-C, drinking, γ-GT, and the N/L ratio, were similar between the two groups. An additional analysis of the association of tumor size with markers showed that lower levels of HDL-C and higher levels of uric acid were associated with increased tumor size (p < 0.05).
CONCLUSIONS: Early-onset CRC precursor cases exhibit higher levels of triglycerides and lower levels of HDL-C than late-onset cases. Additionally, levels of HDL-C are negatively associated with tumor size, whereas uric acid was positively correlated with tumor size.
