FGF-21 Level is higher in patients with breast cancer, a candidate for a new biomarker?

Abstract

Aims: Fibroblast Growth Factor 21 (FGF-21) is a member of the FGF family involved in biological processes such as embryonic development. cell growth. morphogenesis. tissue repair. tumour growth and invasion. with mitogenic and cytogenetic activity at 19q13.33.Breast cancer is a deadly and increasing disease in women. and recent studies have shown a relationship between some cancers. including breast cancer. and hormones secreted from adipose tissue.The aim of the present study was the measurement of FGF-21 levels in patients with breast cancer and its association with breast cancer. Methods: The study included 39 patients with newly diagnosed breast cancer and 39 healthy controls. During the patients’ routine blood tests. a venous blood sample was taken and the serum levels of FGF-21 were determined by ELISA. Results: Demographic and laboratory data were compared between the newly diagnosed breast cancer group and the control group. The control group consisted of 39 participants with a mean age of 52.49 ± 7.02 years. In the patient group. 39 participants with a mean age of 52.15 ± 6.21 years were included in the study. there was no statistical difference regarding age(p>0.05).In the control group. the mean FGF-21 level was 121.35 ± 88.4 pg/ml. while the mean FGF-21 level in the patient group was 171 ± 117.45 pg/ml. a statistically significant difference was detected(p value=0.036). Conclusion: FGF-21 is thought to have significant and beneficial effects on glucose. lipid and energy metabolism. as well as slowing the growth of cancer cells. and may later be used as a biological marker for breast cancer.
