Uncle Wang is 70 years old, has a history of smoking for more than 40 years, this time because of the blood in the sputum to the hospital for examination, found that there is a nearly 3cm lump in the lungs, after bronchoscopy, pathology suggests lung squamous cell carcinoma. However, Uncle Wang has chronic obstructive pulmonary disease, lung function is relatively poor, can not tolerate anesthesia and surgery, what to do? Family members heard that there is an advanced treatment device called "beam knife" and asked patients online if they could be treated with this kind of knife.
"Beam knife" is strictly speaking, not a "knife", but a new type of stereotactic radiotherapy, the full name is the whole body stereo positioning radio wave surgery platform. Also known as "network knife" or "computer knife", it is the world's latest systemic stereotactic radiosurgery treatment equipment. Some people say that the radiation knife to treat tumors can be said to be "knife without marks". Since the development of the beam knife, there has been a sixth generation of equipment in clinical use.
The radiation knife can treat tumors in various parts of the body, and the tumors with good effect include: intracranial tumors, orbital tumors, lung cancer, liver tumors, pancreatic cancer, posterior peritoneal tumors, vertebral tumors, prostate cancers, pelvic tumors, kidney cancers, adrenal metastases, bone metastases and so on. The radio knife generally only needs 3-5 times of irradiation, can kill the tumor tissue, no wound, no pain, no bleeding, no anesthesia, short recovery period, the patient can go home after surgery, the whole process is carried out in a sober, painless state.
When it comes to treating lung cancer, the Beam Knife is now an ideal radiotherapy option. Because of the characteristics of synchronous breathing tracking of the beam knife, even if the tumor is breathing with the patient, the beam knife can accurately guide and tightly clamp the tumor to completely kill the tumor.
For early-stage primary lung cancer, radiotherapy stereotactic radiotherapy has shown good efficacy. Therefore, at present, the radio knife is one of the preferred treatment methods for primary early lung cancers that cannot be operated on or refused surgery, such as advanced age and poor cardiopulmonary function.
For inoperable central lung cancer, radiotherapy stereotactic radiotherapy is also a hot topic for current treatment. As long as the appropriate cases are screened, the appropriate treatment dose and the number of treatments are used, and the efficacy and safety are guaranteed. With the emergence of the new sixth-generation beam knife, the treatment mode of central lung cancer has changed from the traditional conventional segmentation to the large segmentation mode.
For the oligostasis of the lungs that occur in other malignant tumors, the radiation knife also tracks the advantage, and then adds a single oversized tumor killing dose to completely kill the tumor. The control rate of the radiation knife for lung tumors is more than 95%, and it is very rare for the lung metastasis to recur after radiation knife treatment.
To sum up, the advantages of the radiation knife in the treatment of lung cancer are reflected in two aspects:
1. More accurate The use of tumor tracking and positioning system during treatment can completely reduce the side effects of the radiation knife in the treatment of lung cancer, and the total clinical error of the irradiation range does not exceed 1mm, which can greatly protect normal tissues.
2. Suitable for a wide range of people with lung cancer
The treatment process of the beam knife is not limited by the age and physical condition of lung cancer patients, is not affected by underlying diseases such as heart disease, diabetes, and hypertension, and has few contraindications to treatment, especially suitable for patients with early peripheral lung cancer who are not suitable for surgical treatment.
It needs to be clarified that no matter how many advantages the beam knife has, it is ultimately a kind of radiotherapy, which belongs to local treatment, and has a great advantage for small lesions that need to be accurate, especially lesions under 4cm. For large lesions, a wide range of multiple lesions, is not suitable. The disadvantage is that the cost is very high, with a single cost of close to 10,000.
