Significant difference between coagulation parameters and clinicopathological characteristics in breast cancer.

The purpose of this research is to investigate the correlation between coagulation parameters and survival on patients with breast cancer. A total of 244 patients with breast cancer and 84 patients with metastatic advanced breast cancer admitted to the Second Affiliated Hospital of Chongqing Medical University from January 2017 to February 2019 were selected as the research objects. Their age, tumor size, status of estrogen receptor and progesterone receptor status, status of Her-2 receptor and lymph node were evaluated. Additional 99 cases of benign breast tumors were selected as the control group. All patients were newly diagnosed. PTA, PT ratio, PT, APTT, APTT ratio, TT, TT ratio, PT-INR, FIB, and FDP were detected on all patients. There were significant differences in APTT, APTT ratio, FIB, TT, TT ratio, and FDP between breast cancer and benign tumor control group (P < 0.05). The changes of FIB were correlated with age (P = 0.007), PR status (P = 0.017), and Her-2 status (P = 0.008). The older the age, the higher the FIB level. The FIB level of Er negative state is higher than that of positive state, and the FIB level of PR negative state is also higher than that of positive state. Survival analysis showed that PR negative status, the elevated level of APTT, APTT ratio, TT increased, and TT ratio were the indicators affecting 3-year DFS of patients (P < 0.05). Multivariate COX regression analysis showed that APTT and TT were independent prognostic factors affecting 3 years DFS (P < 0.05). Blood hypercoagulable state in patients with breast cancer, abnormal coagulation system plays an important role in the progress of breast cancer.
