Objective To analyze the risk factors of advanced triple-negative breast cancer (TNBC) and establish an effective prognostic nomogram. Methods Screening patients with advanced TNBC by searching the SEER (surveillance, epidemiology, and end results) database, using univariate and multivariate analysis to determine the independent prognostic factors of advanced TNBC, and constructing a nomogram based on it. Results A total of 4 687 patients with advanced TNBC were included. Compared with other types of breast cancer over the same period, TNBC had the worst prognosis. Univariate analysis found that age, gender, stage, surgery, chemotherapy, radiotherapy, and metastasis were associated with a better prognosis (P<0.05). Multivariate analysis found that age, gender, race, stage, surgery, chemotherapy, radiotherapy, and metastasis of the organs were independent factors affecting the prognosis of patients (P<0.05), and constructed a nomogram with a C-index of 0.75 ( 95% CI, 0.71～0.79). The calibration chart showed the best agreement between the predicted overall survival (OS) and the observed OS. Conclusion We analyzed the clinical features of advanced TNBC, provided some prognostic factors for the OS of TNBC patients, and developed a nomogram based on these prognostic factors to help clinicians manage risk and choose long-term survival strategies for TNBC patients.

Objective To investigate the risk factors of developing pulmonary embolism and its influence on the prognosis of lung cancer patients. Methods The following databases such as Wanfang Database, China National Knowledge Infrastructure (CNKI), Chinese Weipu Database, Medline Pubmed and EMBASE were searched to identify relevant articles which were published during January 2000 to March 2020. Statistical analysis was performed using RevMan 5.3 software. Results 9 controlled trials incorporating 1 179 patients were included in this study. The results showed that the overall survival of lung cancer patients complicated with pulmonary embolism was significantly lower than that of lung cancer patients without pulmonary embolism (HR=2.82, 95%CI[2.06,3.87], P<0.000 1). The analysis on risk factors of developing pulmonary embolism showed that adenocarcinoma had a higher risk of pulmonary embolism than non-adenocarcinoma with Odds Ratio (OR)=3.07 (P<0.000 1). Patients in stage III-IV encountered significantly higher risk of pulmonary embolism than those in stage I-II (OR=3.07,P<0.000 1). Furthermore, the risk of pulmonary embolism in patients with high level of D-dimer was 4.32 times higher than in normal patients (P<0.000 1), and 6.62 times higher than those with WBC ≤11×10⁹/L (P<0.000 1). Additionally, the history of chemotherapy and central venous catheterization significantly increased the risk of pulmonary embolism, with OR of 3.02 (P<0.000 1) and 2.30 (P<0.000 1), respectively. However, smoking, alcohol consumption, gender, diabetes, chronic obstructive pulmonary disease (COPD), cardiovascular disease, hypertension were not statistical correlated with the occurrence of pulmonary embolism in lung cancer patients. Conclusion The occurrence of pulmonary embolism significantly affects the prognosis of patients with lung cancer, and the related risk factors were pathological type, stage, chemotherapy, central venous catheterization, increased D-dimer level, and WBC>11×10⁹/L.
