Why does someone need to have iodine-131 treatment after surgery? Iodine-131 therapy is also a kind of adjuvant treatment for thyroid cancer, and there is a difference between those who need it and those who do not. For example, if the tumor has metastasized to the lymph nodes, after the thyroid gland is cut out and the lymph nodes are cleared, there may still be invisible thyroid cells and lymph nodes that exist, and these are potentially risky to kill. Iodine-131 has an affinity with thyroid cells like a missile, which is equivalent to having the thyroid cells eat iodine-131 food with missile properties and then blow up. Iodine-131 treatment is mainly for patients who are clinically considered to have a high probability of recurrence, a high risk of potential metastasis or already have metastasis. Do I need radiotherapy and chemotherapy after thyroid cancer surgery? Generally speaking, papillary thyroid cancer does not require chemotherapy and radiotherapy, but Iodine-131 followed by medication. For undifferentiated and hypofractionated cases, some radiotherapy and chemotherapy are needed. The probability of radiotherapy and chemotherapy for thyroid cancer is relatively low. Most of the patients are treated by surgery plus medication, and then some patients need to do iodine-131 treatment. Many patients are concerned whether they need to take medication for the rest of their lives after thyroid cancer surgery. Thyroid cancer needs to take Eugenol for the rest of your life after surgery. It has two purposes, one is to keep the remaining thyroid tissue from developing, if it is not supplemented half of the thyroid gland is cut and the other half is likely to increase by proxy. Secondly, it has a certain effect of inhibiting recurrence and metastasis. This medicine is taken at the right dose, and as long as the dose is right the side effects are very small, almost no side effects, and it allows you to return to normal levels. Now we believe that taking the drug should also take into account the patient’s situation, there are some heart disease patients take the drug after the heart rate increases, so the dose should be slightly smaller. We have to adjust according to the degree of malignancy of the patient, for example, is easy to relapse easy to metastasize, these people dose slightly larger, of course, in a certain allowable range. If the patient’s lesions are small and the incision is clean, the dose can be a little less. If the patient has a heart condition that does not allow it, you can relax a little and add cardiac drugs. The dose should be individualized and analyzed on a case-by-case basis under the overall decision. In addition, we surgeons should not only think about surgery, but also combine the drugs of internal medicine doctors and ultrasound auxiliary departments to determine whether the patient has recurrence, whether there is metastasis, and whether the drugs are appropriate to eat, through multidisciplinary collaboration to make a comprehensive judgment. Many people are concerned about whether there are any specific requirements for postoperative diet, and whether swallowing affects wound healing. After the surgery, it is recommended that the patient eat a liquid diet, after all, swallowing will be painful. However, we should pay attention to the situation that we should reduce the local activities at the beginning, but we should increase the activities after a period of time, such as a few weeks and a month later, so that we can’t be afraid to swallow at the beginning and become more and more afraid later, and we are afraid to move even if the local neck is swollen. After the operation, you still have to slowly move around and slowly return to a normal state. If you want to do iodine-131, then try to reduce the intake of iodine-containing food and do not eat thyroxine tablets one month before doing it. These iodine-containing food and thyroid tablets will affect the effect of iodine-131, because they both compete, the residual thyroid cells eat thyroxine tablets or even iodine-containing food and are full, and iodine-131 comes in and does not want it. The treatment will be done for nothing. After the surgery, how often do patients care about the review and what are the main items to be checked? Ultrasound is recommended to be done three to six months after surgery, not just one month after surgery, because the local tissues are edematous and the structure is not clear, so the ultrasound is not very clear at this time. It is more reasonable to check again in three to six months.
