The risk factors on the prognosis of pulmonary embolism in tumor patients after the thoracic and abdominal surgery

Background: We studied the clinical profiles and the risk factors on the prognosis of tumor patients with pulmonary embolism (PE) after the thoracic and abdominal surgery Methods: We retrospectively screened patients who underwent the thoracic and abdominal surgery at the Peking University Cancer Hospital from January 1, 2007 to January 1, 2020. Among them, 115 patients who were diagnosed with PE were enrolled in our study. Cox regression was performed for multivariate adjusted factor analyses. Results: The 90-day overall mortality rate was 11.3% in our study. Univariate analysis showed that gender, MPV, shock, oxygenation index and the APACHE II score within 24 hours after diagnosis of PE were statistically significant in the prognosis of PE after the thoracic and abdominal surgery. In multiple cox regression analysis, we found that patients with shock and the APACHE II score within 24 hours after diagnosis of PE were independent risk factors on the prognosis of PE after the thoracic and abdominal surgery (P values of 0.020 and 0.014, respectively). Conclusions: Shock and the APACHE II score within 24 hours after diagnosis of PE were independent risk factors on the prognosis of PE, after the thoracic and abdominal surgery; however, the study power was limited.
