Introduction:

breast cancer has a high incidence; its characteristics and association with other comorbidities arouse the interest of the scientific community.

Objective:

to identify the relationship among clinical, tumoral and molecular characteristics with diabetes mellitus in patients with breast cancer.

Methods:

an observational, analytical and cross-sectional study was conducted in patients with breast cancer attended Tercer Congreso Cancer Treatment Center in the period 2016-2021. The target group consisted of 116 patients. The information was collected from the medical records.

Results:

an association was identified between the ages of 50 or older, the presence of hypertension and a history of ischemic heart disease with the incidence of diabetes mellitus (p<0,05). There was a predominance of patients with tumors between 2 and 5 cm (59,48 %), with a higher prevalence in diabetic women (90 %). The presence of diabetes mellitus was associated with tumor size (p<0,001), metastatic lymph node (p<0,001), with estrogen receptor and human epidermal growth factor receptor 2 subtypes. In diabetic patients the mean tumor diameter was 2,45 ± 0,7, higher than in non-diabetic patients.

Conclusions:

in patients with breast cancer, the presence of diabetes mellitus was associated with tumor size, metastatic lymph nodes, as well as with molecular subtypes related to estrogen receptor and human epidermal growth factor receptor 2. Diabetic patients had a larger tumor diameter.
