Three kinds of drug-eluting bead transarterial chemoembolisation for treating patients with unresectable non-small cell lung cancer

Figure 1 A 66-year-old woman with advanced squamous cell carcinoma treated using drug-eluting bead transarterial chemoembolization in the gemcitabine group. A: Chest computerized tomography examination revealed a malignant tumour (asterisk) in the right upper lung with a severe airway stricture (triangle arrow) and occluded superior vena cava (long arrow); B: A vascular stent was placed in the occluded superior vena cava; C: The right bronchial artery was embolised using gemcitabine-eluting beads; D: The lung tumour (asterisk) was found to shrink at the 2-month follow-up; E: At the 4-month follow-up, a reduction in the lung tumour (asterisk) was observed; F: Complete resolution occurred after 28 months, with an unobstructed superior vena cava (long arrow).
