The primary sites of lung metastases often originate from malignant tumors such as the breast, lung, head and neck, colorectal, and liver. Most patients cannot tolerate surgical resection due to poor underlying lung function, advanced age, and other reasons. With the development of minimally invasive interventional techniques, cryotherapy has become an effective means of local tumor treatment for patients with unresectable lung metastases and has been widely used in clinical practice.
Many patients with tumor recurrence cannot tolerate traditional surgery. These patients generally have poor physical condition, significantly decreased cardiopulmonary function, and other issues, leaving them with only systemic palliative treatment options. Cryotherapy (lung metastases) has become a new method for controlling oligometastatic lesions. By using high-pressure argon gas, which rapidly absorbs the surrounding heat during expansion, the temperature of the surrounding tissues drops drastically, causing tumor cell death and tumor blood vessel rupture, thereby achieving tumor control.
Cryosurgery for lung cancer adopts advanced imaging technology to monitor the ablation range of the tumor in real-time. During the procedure, doctors can clearly see the freezing area, ensuring the precision of the treatment process. In contrast, traditional therapies often struggle to precisely control the treatment range, potentially leading to inadequate or excessive treatment.
Cryotherapy for lung metastases has a minimal impact on lung function because the freezing process mainly targets tumor tissue and has limited damage to the surrounding normal tissue. Traditional therapies such as surgical resection and chemotherapy may significantly impact lung function, causing symptoms such as breathing difficulties. The advantage of cryotherapy allows patients to recover lung function more quickly after treatment, thus improving their quality of life.
During cryoablation lung cancer treatment, the low-temperature stimulation of tumor tissue causes numbness, thereby reducing the patient's pain sensation. Rapid freezing can block nerve pathways and disrupt pain conduction, resulting in an analgesic effect, which serves as a natural anesthetic and minimizes treatment pain, simplifying pain management (only local anesthesia is needed). This allows patients to adapt and recover well, thus it can also be used for cancer pain treatment, intraoperative, and postoperative analgesia in tumor patients.
Cryotherapy for lung metastases has achieved considerable results both in short-term efficacy and long-term control. Compared to other local treatments, cryotherapy has the advantages of real-time monitoring of the ablation range, minimal impact on lung function, and good analgesic effects. Therefore, image-guided cryoablation is a highly advantageous, safe, and effective treatment option for patients with unresectable lung metastases.
