Abstract 1481P

Background

Reportedly up to 30% of lung cancer patients will develop hemoptysis and 10% will experience massive hemoptysis. Bronchial artery embolization (BAE) is routinely performed in patients with hemoptysis secondary to neoplasm, while associated with a high failure rate and increased mortality. The aim of this study was to compare the efficacy of drug-eluting microspheres BAE (DEM-BAE) with blank microspheres BAE (BM-BAE) for hemoptysis in NSCLC patients.

Methods

DEM-BAE was performed in 25 patients with hemoptysis with one vial of 300-500μm Callispheres drug-eluting beads (Gemcitabine 100mg). The BM-BAE group consisted of 25 patients who were treated with blank microspheres of 300-500μm. We categorized the results as technical and clinical success, and also included the mid-term results. Technical success was defined as the complete cessation of the target artery as confirmed by digital subtraction angiography (DSA). Clinical success was defined as the cessation of hemoptysis within 24 h of BAE. Technical success was compared immediately after the procedure. The clinical success and mid-term results (percentage of patients who were free of hemoptysis) were compared at 1 and 6 months after the procedure, respectively.

Results

There was no significant difference for technical success rates (DEM-BAE group: 90%, BM-BAE group: 85%, P>0.05). However, the clinical success rates (DEM-BAE group: 83.3%, BM-BAE group: 68%, P<0.01) and the mid-term results (DEM-BAE group: 71.4%, BM-BAE group: 64%, P<0.01) showed a significant difference. Moreover, Disease control rate (CR+PR+SD) was higher in DEM-BAE group than control group (DEM-BAE group: 78.5%, BM-BAE group: 48%, P<0.01). The procedure-related complications included mild cough and mild chest pain. There was no special management required for these complications.

Conclusions

DEM-BAE appeared to be the more optimal modality to improve the mid-term clinical efficacy compared to blank microspheres BAE for hemoptysis in NSCLC patients. Further studies were warranted.
