After surgery, how long can I last with 40 iodine particles, and then put it a second time

I am a victim of radioactive particles, in 2013 I had a tumor on the back and outside of my right thigh, rhabdomyosarcoma, (Beijing 301 Hospital diagnosed and operated) at the same time as removing the part of the muscle bundle with the tumor, the radioactive particles were placed during the operation, less than three months after the operation, the manifestations of nerve damage began to appear, and the progressive aggravation finally the doctor said that the particles may have migrated and damaged the nerves, and a detective operation was done one year after the operation, and some of the particles were removed. During the operation, I saw that the surrounding tissues of each particle were edematous, hard and inelastic, and now the tumor has no tendency to deteriorate, but the damage caused by the implantation of radioactive particles (right sciatic nerve injury) has seriously affected my life and quality of life, and I have lost my love of work and normal life and posture (neuralgia caused by nerve damage, muscle atrophy) In the past 5 years, I have been suffering from endless torture caused by nerve damage. Is life important or quality of life important?

The half-life of i125 is 60 days, which means that it will decay by half in 2 months. To disappear, it will take a long time to take it out if you feel that ** is up to expectations. However, the killing radius of I125 is very small, so the nuclide of I125 is selected.

Implantation of iodine particles only treats the metastatic tumor lesions that can be found on the image, but does not treat the lesions that have not yet formed to the point where the image can be seen, so it is necessary to inhibit the growth of the cancer that is still forming a large lesion in order to prolong the survival time of the patient. If you want to extend this aspect, you can give specific advice.

This is a method of implanting a radioactive source inside the tumour and allowing it to continuously release rays to destroy the tumor. Particle implantation** technology involves radioactive sources, the core of which is radioactive particles. As long as you don't come into contact with particles for a long time, there is not much of a barrier.

Particle Meaning: Particle refers to the smallest component of matter that can exist in a free state. The first particles to be discovered were atoms, electrons, and protons, and in 1932, neutrons were discovered, confirming that atoms are composed of electrons, protons, and neutrons, which are more basic components of matter than atoms, so they are called elementary particles.

In the future, more and more such particles have been discovered, and the cumulative number has exceeded hundreds, and there is a trend of increasing. In addition, some of these particles have not been found to have an internal structure in experiments so far, and some particles have been shown to have obvious internal structure. It seems that these particles do not belong to the same level, so the term elementary particles has become history and are now collectively referred to as particles. Particles are not concrete substances that actually exist such as neutrons and protons, but they are collectively referred to as a model.

Radioactive particle implantation technology mainly relies on the stereotactic system to accurately implant radioactive particles into the tumor, and emits continuous, short-distance radiation through a miniature radioactive source, so that the tumor tissue suffers maximum damage, while the normal tissue is not damaged or only slightly damaged. Experts believe that compared with other tumor technologies, radioactive seed implantation technology itself is not high in technology and is not very difficult. However, since it is directly implanted in the human body and is a radioactive source, it is necessary to strictly grasp the indications.

During the period of seed implantation, colds should be avoided, the daily diet should be light, and more attention should be paid to the nutritional value of food, and patients should choose fresh fruits and vegetables with rich vitamin content to eat. Lung cancer patients can take traditional Chinese medicine ginseng RG3 during the seed implantation period, which is taken from the precious ginseng essence extract, which has high nutritional value, and for tumor patients, it also has an anti-vascular effect.

Seed implantation** dates back to the beginning of the last century. As early as 1909, the Radium Radiation Biology Laboratory in Paris, France, used a catheter to insert radium with a cladding into the prostate, completing the first case of close-up prostate cancer. However, due to improper dosage control, the early technique can cause serious damage to the rectum of patients, so it is not widely used.

It wasn't until 1931 that Swedish researchers came up with the concept of proximity and invented a method for calculating doses, which reduced the risk of complications. In the 70s of the last century, the Memorial Hospital of New York in the United States pioneered the implantation of prostate cancer through retropubic interstitial iodine particles, forming the foundation of today's prostate cancer. Radioactive seed implantation of early prostate cancer has become a standard means in the United States and other countries, and its concept has gradually been recognized in China.

Particles can also damage other cells in the body, causing damage to other functions.

Thank you and good luck soon**! Under the guidance of the doctor, I was determined to choose the low-risk seed implant for my father, but now I am afraid of making the wrong choice.

"Particles" are special particles made of radioactive substances that are implanted into tumors for "internal radiotherapy". In recent years, due to the successful development of "particles" and the continuous progress of speculum technology, the technology of radioactive particles for close-up tumors has been rapidly developed. At present, the application of seed implantation at home and abroad has achieved encouraging results in the treatment of lung, liver, pancreas, prostate, lymph nodes, breast and other tumors, and many inoperable patients have been effective.

1. Life-threatening: some tumor patients may have a decrease in hematopoietic function after anti-tumor**, if the prediction is not accurate, after taking iodine-125 particles implanted**, it may cause worse hematopoietic function, and the patient unknowingly, the white blood cells, red blood cells, and platelets in the blood will be significantly reduced, and in severe cases, it will be life-threatening;

2. Particle shedding: If the particles fall off or are lost, it will cause great damage to the surrounding objects and life. The use of iodine-125 particles in hospitals requires the ingestion of these substances through isotopes.

Therefore, only hospitals with isotope particle storage and transportation qualifications can apply iodine-125 particle implantation**.

First of all, scientific research has confirmed that there are no injurious injuries. In the end, it should be said that there is no harm, as long as people have ray damage in the universe, this cannot be identified for particles; It takes three factors to decide: time, dose, and distance. But you can rest assured.

It's okay to contact it for a short time.

There will be an impact, but it is uncertain whether it can cause harm, because the radiation effect has individual differences and linear domainless characteristics, so it is better to have less exposure!

It is best for pregnant women not to go to see it, and to stay away from the patient (implant site) to see it, and try to spend as little time as possible. But in general, the probability of being hurt is still very low, so don't worry even if you go. Radioactivity is everywhere, and environmental radiation accumulates a lot, so going to the hospital will not increase the radiation dose.

In short, pregnancy, especially in the first trimester, should be less exposed to radiation, but there is no fear because the dose estimate is still very small.

Description of the condition (onset time, main symptoms, hospital, etc.): The specific onset time is not clear, and the disease felt a dull pain in the left abdomen in November last year. Ever ** situation and effect:

After feeling pain, I always thought it was a problem in the stomach, and the natural ** effect was not good. Until the sixteenth day of the first month of this year, I went to the county people's hospital for examination, including CT and B-ultrasound. A tumor in the spleen is found, and doctors consider it a spleen hemangioma or lymphoma.

After the operation, a pathological analysis report was made, and the result was inflammatory malignant fibrous histiocytoma of the spleen. In addition, during the operation, it was found that there was a tumor in the abdominal cavity near the spleen or on the surrounding glands, and the doctor said that it could not be removed. Last month, I had an iodine particle implantation operation at the Jiangxi Provincial Cancer Hospital, and the doctor looked at the situation inside:

In the back and lower part of the pancreas, in front of the left renal hilum saw a lump of about the size, the lump was very hard, and there were many lymph nodes wrapped outside, the doctor said that it could not be pulled out at all, so it could only be implanted with particles, and the doctor said that the implantation effect would be rechecked after a month, but when he was discharged, the doctor said that the prognosis effect may not be ideal, because the lymph nodes around it and the intestine have adhesions, in order to avoid intestinal fistula and pancreatic fistula, so the position of the particles is not very ideal. How can I get help: I would like to ask Dr. Yang:

If my dad's tumor is found to have unsatisfactory results in the re-examination, can I still undergo radiofrequency ablation? Last time, I also consulted you, you said that you can use radio frequency to cooperate with ** when implanting particles, I don't know if Jiangxi Provincial Cancer Hospital did not carry out or how, did not use radio frequency cooperation**.

The value of 125 iodine particles is suitable for cancer patients who are suitable for radiotherapy**, such as head and neck tumors, can be considered for this ** if they follow the doctor's advice. In order to alleviate the risk of the drug, patients can take ginseng Baiyi during the medication, which can reduce the adverse reactions of the drug and improve the patient's immunity. It still has obvious advantages for some patients with tumors with ** or limited metastasis after surgery.

1.Tumor iodine 125 particle implantation is advanced in technology, good in efficacy, and small; 2.At the same time of chemotherapy, iodine 125 particles can be implanted, chemotherapy covers the "surface", iodine 125 particles are implanted to highlight the "point", and the "point, surface" are combined for synthesis**; or color ultrasound guidance, percutaneous puncture of iodine 125 particles implantation**, which can achieve the effect of bladeless surgery, but the trauma is small, and the patient can be discharged 2 days after surgery; 4.

Intraoperative iodine-125 particle implantation** can expand the scope of surgery and obtain better curative effect; 5.Iodine-125 particle implantation** is the best choice for patients who do not respond to chemoradiotherapy**; 6.Although iodine-125 particles are radioactive, the range of iodine-125 particles does not need to consider environmental pollution and protection issues; 7.

This technique is complex and needs to be carried out jointly by the Department of Nuclear Medicine and the Department of Interventional Medicine (Radiology), Surgery, Magnetic Resonance, Ultrasound and Endoscopy.

Iodine-125 particle implantation has rarely been reported for the treatment of lung cancer. Be cautious, and those who listen too much will regret it.
