Abstract

Background: We evaluated the incidence and effect of thromboembolic events (TEEs) in patients with muscle-invasive bladder cancer treated with preoperative chemotherapy (POC) and radical cystectomy (RC) with pelvic lymph node dissection (PLND). Patients and Methods: We performed a retrospective review of all patients who had undergone POC followed by RC plus PLND for muscle-invasive bladder cancer from June 2000 to January 2013 (n = 357). The chemotherapy type (neoadjuvant vs. induction), incidence and timing of TEE diagnosis (preoperatively vs. ≤ 90 days postoperatively), and effect of TEEs on clinical outcomes were recorded. Results: Overall, 79 patients (22%; 95% confidence interval [CI], 18%-27%) experienced a TEE: 57 (16%) occurred during POC and 22 (6.2%) were diagnosed postoperatively. Forty patients (11%; 95% CI, 8.1%-15%) required an inferior vena cava filter. We found no significant differences in neoadjuvant versus induction chemotherapy and the risk of TEEs (difference, 3.3%; 95% CI, -5% to 12%; P = .5). No significant difference were found in the rates of POC completion according to the presence of a TEE (difference, 1.0%; 95% CI, -11% to 13%; P = .9). The occurrence of TEE did not significantly affect other perioperative outcomes. The risk of recurrence and overall survival were not associated with TEE on multivariable analysis. Conclusion: We found a high incidence of TEEs (22%) in patients undergoing POC before RC plus PLND, with a 16% incidence in the preoperative period. TEEs in the POC setting leads to invasive procedures; however, we did not find a significant effect on POC completion or postoperative complication risk. Further research is required to determine whether preventative TEE measures during POC can improve clinical outcomes.
