ABSTRACT
Background:
Transcatheter bladder arterial chemoembolization (TACE) is an alternative treatment used to control bladder cancer (BC) with bleeding, especially in older adult patients with comorbidities. This retrospective observational study evaluated the effect and prognostic factors of transcatheter drug-eluting bead (DEB) embolization in patients with advanced BC.Methods:
We assessed 39 patients diagnosed with BC with hemorrhage who were either inoperable or unwilling to undergo surgery at our hospital between January 2018 and October 2022. All patients underwent TACE by DEB loaded with epirubicin and imaging scans after 2 months to evaluate the curative effect according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST) standard to determine treatment. Re-examination and follow-up were performed every 3-6 months to observe hematuria recurrence and the curative effect.Results:
A total of 95 interventional treatments were performed in 39 patients, and all participants achieved complete hemostasis within 5 days after the first intervention. Computed tomography or magnetic resonance imaging showed that the total effective rate [complete response (CR) + partial response (PR)] was 64.1%, and the disease benefit rate (CR +PR + stable disease) was 79.5%. A total of 30 patients (76.9%) had no hematuria recurrence. Logistic regression analysis indicated that the type of blood supply in BC may relate to whether the patients benefited from the intervention. Hematuria recurrence was significantly associated with the total number of tumors and the type of blood supply (P<0.05).Conclusions:
Superselective embolization of bladder arteries with DEB can be used to treat BC with hemorrhage. However, hypovascular tumor blood supply may result in poor postoperative efficacy and hematuria recurrence. Additionally, multiple bladder tumors may be a risk factor for hematuria recurrence.
