Lung Adenocarcinoma With Intratumoral Necrosis Induced by Bronchial Artery Embolization

Key Points

To investigate the effects of bronchial artery embolization on lung adenocarcinoma tumor behavior and pathology.
Patient presented with hemoptysis due to a solid tumor in the right upper lobe.
Bronchial artery embolization was performed using gelatin sponge to control bleeding.
Chest computed tomography was used to assess the tumor after two weeks, revealing a cavity.
Pathological staging was confirmed after right upper lobectomy.
The procedure successfully controlled bleeding and induced tumor necrosis and cavitation.
Fluorodeoxyglucose uptake showed no activity in the necrotic tumor but was present in the lymph node.
Patient remained recurrence-free for over 5 years after adjuvant chemotherapy.

Abstract

ABSTRACT A 70‐year‐old woman presented with hemoptysis due to a right upper lobe mass. Bronchial artery embolization (BAE) using gelatin sponge was successful in controlling bleeding. Two weeks later, chest computed tomography (CT) revealed that the solid tumour had been replaced by a 5.6 cm thin‐walled cavity without fluorodeoxyglucose uptake on positron emission tomography–computed tomography, although fluorodeoxyglucose accumulation was observed in the right hilar lymph node. Right upper lobectomy confirmed adenocarcinoma. The patient, confirmed with a pathological stage of IIIA, received adjuvant chemotherapy and has remained recurrence‐free for more than 5 years. This case suggests that BAE induced tumour necrosis and cavitation; however, viable tumour tissue remained. Further accumulation of similar cases is needed to clarify the therapeutic significance of BAE in lung cancer.
