Abstract Purpose: Diabetes Mellitus (DM) has been one of the well known risk factors of breast cancer (BC) development and also associated with adverse clinical outcomes of BC patients. Glucagon-like peptide-1 (GLP-1) receptor agonists have been used as antidiabetic therapeutic agents and recent epidemiological studies have reported their use to be correlated with increased BC risks. However, biological or pathological details have remained unknown. Therefore, in this study, we examined the status of GLP-1 receptor (GLP-1R) in BC with and without DM and correlated the findings with the clinicopathological factors of the patients to explore the possible involvement of GLP-1 in BC pathology.Methods: We immunolocalized GLP-1R in cancer and adjacent non-pathological breast tissues in BC patients with DM (125 cases) and without DM (58 cases). We then compared the status of GLP-1R with that of fibroblast growth factor 7 (FGF7) and fibroblast growth factor receptor 2 (FGFR2), Ki-67 labeling index (Ki-67 LI) and disease free survival (DFS) of the patients and also between cancerous and non-pathological breast tissues.Results: GLP-1R immunoreactivity was significantly higher (p=0.044) in the patients with DM than without in carcinoma tissues. However, this was detected only in invasive carcinoma (p<0.01) and not in non-invasive carcinoma nor non-pathological mammary glands. FGF7 was significantly correlated with the status of GLP-1R in BC (p=0.045). In addition, in ER positive BC cases, those with GLP-1R positive status tended to have higher Ki-67 LI of more than 14% (p=0.070).Conclusion: These findings all demonstrated the possible association between GLP-1R status and biological features of BC, especially of invasive BC in DM patients.

Due to the high efficiency of glucagon-like peptide-1 (GLP-1) receptor agonists therapy in only a part of patients, the search for predictors of response to the treatment is a relevant problem. Purpose. The purpose is to compare the efficacy of liraglutide and exenatide therapy in obese patients with type 2 diabetes mellitus (T2DM) and to evaluate the predictors of response to glycated hemoglobin (HbA1c), weight and lipids reduction. Material and methods. The study included 47 patients with type 2 diabetes and obesity who received GLP-1 receptor agonists therapy. 26 patients were treated with liraglutide, 21 patients were treated with exenatide. We measured the parameters of carbohydrate and lipid metabolism, the levels of hormones involved in glucose and lipids metabolism and in appetite regulation. Blood pressure was measured. These parameters were evaluated at baseline and after 24 weeks of treatment. Results. Patients receiving exenatide therapy showed a tendency towards more frequent HbA1c level reduction by 1% or more (60% versus 30.4%, p = 0.07). The effects of liraglutide and exenatide on weight and waist circumference were comparable. When assessing the predictors of response to the therapy, a more pronounced decrease in HbA1c level (by 1% or more) was in the patients with a higher initial HbA1c level (8.7 (8.2; 9.7) versus 8.2 (6.9; 8.7)%, p = 0.04), as well as with a higher initial GLP-1 level (0.12 (0.05; 0.17) versus 0.040 (0.01; 0.09) ng/ml.) A more significant decrease in the triglycerides (TG) level was detected in patients with a higher level of glucose-dependent insulinotropic peptide (GIP) before therapy (409 (316.0; 431.4) pg/ml in patients who reduced TG level by 30% or more and 331.5 (324.9; 367.1) pg/ml in patients with a lower decrease in TG level). Among the studied parameters, no predictors of body mass reduction were revealed. Conclusion. Measurement of HbA1c, GLP-1, GIP level may be useful to predict the efficacy of GLP-1 receptor agonists therapy.
