Abstract
Background: Breast cancer is frequently associated with activation of the hemostatic system and the extent of this activation correlates with a more advanced tumor stage. D-dimer is a biomarker that indicates the activation of hemostasis and fibrinolysis.Methods: This is a prospective, observational, analytical study in which we compare plasma D-dimer levels among three groups’ i.e., healthy subjects, benign patients and breast cancer patients. We have also evaluated plasma D-dimer levels in patients with lymphadenopathy and in those patients who did not have palpable lymph nodes. Plasma D-dimer levels were further characterized based on TNM classification in breast cancer patients where quantitative D-dimer levels were correlated with clinical stage grouping.Results: Through our study we have observed that D-dimer level is inexpensive and a convenient method for diagnosis and prognosis of breast cancer. We have used a control group so as to evaluate a more accurate result. Comparison between benign and malignant lesions was made and we have achieved a significant p value, which proved our study positive for raised D-dimer levels in cancer breast.Conclusions: D-dimer proves to be a safe, convenient and easily available biomarker which can be combined with conventional sentinel node biopsy in clinically node negative breast cancer to assess metastatic disease in axilla and reduce false negative results. Plasma D-dimer level was positively correlated with clinical stage of solid cancers.
