Abstract
Introduction: Thrombocytosis and type 2 diabetes have negative effect on the survival of tumor patients. Previously, their joint effect has not been studied in breast cancer. Aim: The aim of our retrospective study was to investigate the occurrence and effects of thrombocytosis and/or type 2 diabetes in breast cancer patients who attended the 2nd Department of Internal Medicine or the 1st Department of Surgery, Semmelweis University, between 2014 and 2017. Laboratory and anamnestic data were compared at the time of tumor diagnosis between diabetic and non-diabetic groups. Survival analysis was performed to study the effects of thrombocytosis and/or type 2 diabetes. Method: 274 study participants were followed until 31 December 2018, or until their last appearance at the University, or until their death. Results: 5% of the patients had elevated platelet counts (over 400 G/L), and 52 were diabetics. Diabetics were significantly older (non-diabetics: 56.8 ± 13.8 years, diabetics: 67.8 ± 11.0 years, p<0.0001). Triple negative subtype (p = 0.0366), and T1 stage (50%) were present more often in non-diabetics. Stage T2 was more common in diabetic patients (51.9%). Type 2 diabetes was associated with a shorter survival time (p = 0.0032). Thrombocytosis did not affect patient survival. Conclusion: At the diagnosis of breast cancer, existing type 2 diabetes is associated with a more severe clinicopathological stage and shorter survival. We recommend that during routine diabetes controls, women should be made aware of the importance of mammography screening. Moreover, diabetes should be considered as a risk factor; after 30 years of age, diabetics should be screened at least every two years. Orv Hetil. 2019; 160(51): 2012-2020.
