[Evaluation of new style of drug delivery system for primary lung cancer: intermittent intra-arterial injection therapy with subcutaneous infusible port I.--Temporary changes in feeding arteries of lung cancer in processes of intra-arterial injection therapy].
Arterial injection therapy for lung cancers is concentrated on the bronchial arteries, because they are reported by the main feeders of lung cancers. In the present study, we attempted intermittent arterial injection therapy with implantable port system. In the cases of lung cancers, in the present study, tumors were mainly fed by bronchial arteries originating from intercostal-bronchial arteries in right lungs, and those directly originating from aorta in the left lungs. However, in the processes of BAI (Bronchial Arterial Injection Therapy), main feeders often were obstructed and the new feeders originated from branches of subclavian arteries, such as thyro-cervical truncks, internal mammary arteries, thoraco-acromial arteries and intercostal arteries. They formed networks surrounding the lungs. Adequate study of the feeding arteries should be performed in the course of arterial injection therapy of lung cancers.
