[이데일리 이순용 기자] The colorectal cancer team at Kangbuk Samsung Hospital (Radio Medicine Professor Hyun-Pyo Hong, Professor Ham Yeon-yeon, Surgery Professor Hyung-Wook Kim, Department of Hematology and Oncology Professor Dong-Hoe Koo) confirmed the effect of radiofrequency ablation therapy on patients with lung metastases from colorectal cancer.
In general, when lung metastasis occurs in colorectal cancer, surgical resection is performed in the case of a small number of lung metastases. However, if lung resection is performed, symptoms such as reduced 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 times of pulmonary radiofrequency ablation therapy performed on 31 patients with colorectal cancer with lung metastasis determined through multidisciplinary treatment. Most of the patients were hospitalized for a short period of 2 nights and 3 days and were treated with local anesthesia. The treatment outcome was 81% and 64% for 1-year 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% radiofrequency surgery success rate was recorded. Postoperative complications such as pneumothorax occurred in about 18%, but there were no cases that were clinically significant.
Professor Hong Hyeon-pyo said, “In the case of colorectal cancer lung metastasis radiofrequency ablation, it is difficult to perform and is not actively performed in Korea, but we have accumulated a lot of clinical experience by actively implementing it at our hospital. I will do my best,” he said.
Professor Koo Dong-hoe said, “Through this study, it was confirmed that radiofrequency ablation therapy can be an effective treatment for colorectal cancer lung metastasis. revealed
The study results were published in the latest issue of the Asia-Pacific Journal of Clinical Oncology.
