Analysis of clinical data in breast cancer patients with type 2 diabetes

Abstract

Objective To investigate differences of ctinicopathologic features in breast cancer patients with or without Type 2 Diabetes Mellitus(DM).Methods The general conditions and elinicopathologic features of the hospitalized breast cancer patients with or without type 2 diabetes were analyzed using a case-control study.Results The average age,fasting blood-glucose,BMI and TG were(58.4 ± 7.80),(8.15 ± 2.80)mmol/L,(27.72 ± 3.47)mmol/L and(2.36 ± 1.18)mmol/L in patients with DM,and(51.6 ± 9.90),(5.13 ±0.63)mmol/L,(24.15 ± 4.95)mmol/L and(1.32 ± 0.59)mmol/L in patients without DM.There were significantdifference between the two groups(t =2.968,P =0.004; t =5.757,P ＜ 0.001 ; t =3.235,P =0.002; t =4.330,P ＜0.001,respectively).HDL-C in patients with DM was(1.39 +0.20)mmol/L,which was significantly lower than that of(1.50 ± 0.24)mmol/L in patients without DM(t =2.000,P =0.05).TC and LDL-C was(4.89 ± 1.16)mmol/L and(3.02 ±0.90)mmol/L in patients with DM,which were not significantly different with those of(4.79 ±0.85)mmol/L and(2.97 +0.61)mmol/L in patients without DM(t =0.396,P =0.693,and t =0.255,P =0.800,respectively).More patients were in the menopausal status in breast cancer patients with Type 2 DM compared to the other group(x2 =11.835,P =0.001).The expression of Her-2 was 76.7％(23/30)in breast cancer patients with Type 2 DM,which was significantly higher than that of 50.8％(33/65)in patients without DM(x2 =5.689,P =0.017).Conclusion The average age was higher in breast cancer patients with Type 2 DM and most of them were in their menopausal status,furthermore the higher body mass index and worse prognosis were observed in this group,so the breast cancer patients with diabetes should choose the more reasonable treatment.
