Serum irisin levels in colorectal cancer patients

Abstract

OBJECTIVE: There are limited studies investigating the role of irisin in colorectal cancer, and the results are diverse. The role of irisin in colorectal cancer patients was investigated in this study. PATIENTS AND METHODS: This cross-sectional study included 53 patients diagnosed with colorectal cancer (CRC) and 87 healthy volunteers. Serum irisin, glucose, insulin, C-peptide, and whole blood hemoglobin A1c (HbA1c) levels were measured in venous blood samples taken from patients and the control group. RESULTS: The mean serum irisin levels were significantly lower in the patient group (23.97 ± 16.94 ng/mL) than in the control group (32.71 ± 17.26 ng/mL) (p = 0.004). Serum glucose levels were 96.58 ± 15.12 mg/dL in the patient group and 81.91 ± 11.24 mg/dL in the control group. Serum glucose levels were significantly higher in the patient group than in the control group (p < 0.01). In the patient group, there was no statistically significant difference between metastasis (+) patients and metastasis (-) patients in terms of serum irisin levels (27.53 ± 18.48 ng/mL and 21.23 ± 15.43 ng/mL, respectively; p = 0.182). CONCLUSIONS: Our study has provided new insights into the potential role of irisin in CRC. However, further studies, including in vitro, in vivo, and larger patient groups, are necessary to fully understand the potential of irisin as a biomarker or therapeutic target for CRC and other diseases. © 2023 Verduci Editore s.r.l.
