Regional lung chemotherapy techniques

Selective delivery of chemotherapy to an affected organ or region of the body promises improved drug efficacy for the targeted area while minimizing the systemic exposure and toxicity. Several intravascular surgical techniques to achieve targeted regional lung chemotherapy have been developed. Investigations have been carried out to determine the feasibility, safety, and efficacy of these techniques in the primary or adjuvant setting with the intent to palliate or cure. This overview describes the history, rationale, technical aspects, and clinical experience of four regional lung chemotherapy techniques delivered by vascular manipulations including bronchial artery infusion, pulmonary artery chemoembolization, isolated lung perfusion, and lung suffusion.
