Abstract

BACKGROUND: Neoadjuvant chemoradiotherapy (CRT) in esophageal cancer (EC) patients may increase the formation of thromboembolic events (TEEs). We analyzed the incidence and impact of TEEs in EC patients treated with platinum-based CRT.

METHODS: A total of 336 patients with EC underwent an esophagectomy, of which 110 patients received neoadjuvant CRT (41.4 Gy with concurrent Carboplatin/Paclitaxel). Patients were matched based on pre- and perioperative characteristics.

RESULTS: Preoperatively, 9 (8.2%) patients with neoadjuvant CRT (P = .004) were diagnosed with TEEs. Despite delay until surgery (P = .021), the postoperative course did not differ. In multivariate analysis, a history of deep vein thrombosis (P = .005) and neoadjuvant CRT (P = .004) were identified as risk factors. Postoperatively, there were no differences in TEEs (P = .560) observed. In multivariate analysis, a history of pulmonary embolism (P = .012) was identified as a risk factor for postoperative TEEs.

CONCLUSIONS: Preoperatively, EC patients treated with neoadjuvant CRT have an increased risk to develop a TEE, especially those with a previous history of TEE. After surgery no increased incidence was observed. We recommend secondary prophylaxis during neoadjuvant treatment in this high-risk group. (C) 2014 Elsevier Inc. All rights reserved.
