A colorectal cancer lung metastasis patient confirmed the effect of radiofrequency ablation

[이데일리 이순용 기자] The colon and rectal cancer team at Kangbuk Samsung Hospital (Professor of Radio Medicine Hyun-Pyo Hong, Professor Ham Yeon-yeon, Professor of Surgery Hyung-Wook Kim, Department of Hemato-Oncology Professor Dong-Hoe Koo) confirmed effect of radiofrequency ablation therapy on patients with lung metastases from colorectal cancer.

In general, when lung metastases occur in colorectal cancer, surgical resection is performed in the case of a small number of lung metastases. However, if a lung resection is performed, symptoms such as decreased lung function may occur after surgery. In addition, when radiation treatment and chemotherapy are performed, there is a possibility of side effects at the radiation treatment site. Accordingly, as one of the ways to overcome this problem, Professor Hong’s team conducted a study to confirm the effect of high frequency thermal therapy for metastatic lung cancer.

Radiofrequency thermal therapy for lung cancer is a technique that treats tumors by generating heat after inserting a surgical instrument into the lesion inside the lung through a safe route under the guidance of radiology equipment such as CT and ultrasound. Radiofrequency ablation, one of the local treatments, is recognized as an alternative treatment for malignant tumors of the liver, lungs and kidneys, which are difficult to operate.

The research team at Kangbuk Samsung Hospital analyzed 48 sessions of pulmonary radiofrequency ablation in 31 colorectal cancer patients with lung metastases determined by multidisciplinary treatment. Most of the patients were in hospital for a short period of 2 nights and 3 days and were treated with local anaesthesia. Treatment outcome was 81% and 64% for 1- and 2-year local recurrence-free survival, respectively, and 98% and 97% for overall survival, respectively.

In particular, as a method of reconstructing 3D tomographic images, the target was precisely targeted with cone beam CT, and a 90% success rate of radiofrequency surgery was recorded. Post-operative complications such as pneumothorax occurred in approximately 18%, but there were no clinically significant cases.

Professor Hong Hyeon-pyo said, “In the case of colorectal cancer lung metastases radiofrequency ablation, it is not actively performed in Korea due to the difficulty of the treatment, but we have accumulated a lot of experience clinical by implementing it in our hospital. .” I will do my best,” he said.

Professor Koo Dong-hoe said, “Through this study, it has been confirmed that radiofrequency ablation therapy can be an effective treatment for colorectal cancer lung metastases.”

The results of the study were published in the latest issue of the Asia-Pacific Journal of Clinical Oncology.
