Lung chemoembolization

Lung chemoembolization is a new treatment option for lung cancer that is not responding to systemic therapy and cannot be cured with surgery or radiation. Rather than injecting chemotherapy into a vein, the chemotherapy is delivered directly into the tumor, which potentially reduces side effects and improves efficacy.

During the chemoembolization procedure, a small catheter is placed into the artery that supplies blood to the lung tumors. Chemotherapy is injected into the tumor-feeding artery, followed by small plastic beads to block off the blood supply to the tumors. Often, only a single outpatient treatment procedure is needed. Large tumors, or tumors in both lungs, can require 2-4 treatment procedures.

Lung chemoembolization is commonly performed in Europe and Asia, where studies have shown response rates of 48 - 78%, with no major complications reported. However, lung chemoembolization is considered experimental in the United States. Our group has the most experience with lung chemoembolization in the US, and we have now started a phase II research study to examine the safety and efficacy of lung chemoembolization for treating non-small cell lung cancer. We are currently the only site in the US offering this localized chemotherapy treatment.
