[Reporter Ding Weijie/Chiayi Report] Mr. Wang, who lives in Alishan, Chiayi County, underwent surgical resection for lung cancer last year. Unfortunately, the tumor recurred this year. He was unable to undergo surgery due to his old age and poor lung function. After evaluation by Chiayi Hospital, he was arranged to receive five "stereotaxic radiotherapy" sessions, which accurately focus the radiation on the lesions and reduce the impact on surrounding normal tissues. Recent follow-up CT scans also showed that the tumor had disappeared, allowing Mr. Wang to regain his health.

"Aren't tumors fixed?" Many people don't know that when tumors appear in the lungs or liver, the tumors may move up and down with breathing, like a "moving bullseye" that keeps shaking. The Radiation Oncology Department of Geigy introduces a high-precision navigation curved knife, which combines image navigation and respiratory control technology to accurately focus radiation on the lesion while minimizing the impact on surrounding normal tissues, and tailor-made personalized radiation treatment strategies for patients.

Zhang Zhijia, director of the Department of Radiation Oncology at Geiji, said that for tumors that move with breathing, such as lungs and livers, SBRT (stereotactic body radiotherapy) can be used, combined with respiratory control and image navigation technology, to grasp the changes in tumor position during the treatment process and concentrate high-dose radiation on the target area. This type of treatment particularly emphasizes "precision", hoping to effectively control tumors while reducing the chance of normal tissue receiving unnecessary radiation.

In addition to tumors in the body, brain tumors can also be treated with high-precision radiation through SRS (stereotaxic radiosurgery). SRS is not a traditional surgical operation. Instead, it uses highly concentrated and precise radiation to treat brain tumors and reduce the impact on surrounding normal brain tissue. For some patients who are not suitable or do not need traditional surgery, doctors can evaluate whether they are suitable for this treatment method.

Geigy stated that some of the treatment items in this project are eligible for health insurance payment. Whether they are actually eligible for payment depends on the individual patient's condition and health insurance regulations, and will be explained by the doctor after evaluation. If you have any questions, you can confirm with the doctor.
