Background:
Pulmonary carcinoid tumors represent indolent neuroendocrine neoplasms for which surgery remains the standard of care. Patients ineligible for surgery or radiation have limited treatment options. Endoscopic pulsed-electric field (PEF) ablation via robotic-assisted and non-robotic assisted bronchoscopy platforms is emerging as a minimally invasive alternative for lung malignancies.
Methods:
A multicenter retrospective study of patients with pulmonary carcinoid lesions treated with bronchoscopic PEF ablation. ssRAB or EBUS were used to navigate to the target lesions and deliver PEF ablation via a 21-gauge needle, tool-in-lesion confirmed by mobile cone beam computed tomography (CT). Procedure details, intra- and post-procedural complications, and follow-up chest CT were assessed for tumor response and safety outcomes.
Results:
Ten carcinoid tumors from eight patients were successfully ablated. The mean tumor size reduction was 8.10 mm or an overall percentage reduction of 53.9%, range 25-100%. No major complications occurred. Three patients presented mild intraprocedural bleeding. The median follow-up time was 3.5 months (IQR 3-4.5). One patient underwent re-ablation due to tumor recurrence without complications, and two PPN showed complete resolution at follow-up.
Conclusions:
PEF ablation delivered via ssRAB and EBUS for pulmonary carcinoid tumors appeared feasible and safe, with promising short-term radiographic responses. This approach may provide a minimally invasive treatment option for patients who are not candidates for surgery or radiation.
