the Microbiota Are Associated With Iodine-131 Therapy and Hypothyroidism

Thyroid cancer is a common neck malignancy. Currently, total thyroidectomy or subtotal thyroidectomy is the main method for the treatment of thyroid cancer patients. However, some thyroid cancer may still have residual thyroid tissue after operation. Therefore, in the differentiated thyroid In the treatment of cancer, iodine 131 treatment is mainly used because iodine 131 can emit high-energy beta rays, destroying the residual tissue of thyroid cancer and achieving good therapeutic goals. However, in the treatment of iodine-131, certain salivary glands are inevitably damaged, and the patient will have dry mouth symptoms. After the same treatment with iodine-131, some patients will experience gastrointestinal reactions such as nausea and vomiting. The therapeutic efficacy of iodine-131 depends on the lesion's uptake of iodine-131, which requires an increase in serum TSH levels. All patients in this study had stopped taking thyroid hormone for 3-4 weeks before iodine 131 treatment, making serum The TSH level is greater than 30 mU/L. At this time, the patient is in hypothyroidism. People with hypothyroidism experience dry mouth, dry skin, constipation, pain, cold, poor memory, depression, and weight gain. Many studies have pointed out that some cancer treatments, such as chemotherapy and radiotherapy, also have an impact on the microbial flora. However, studies on the relationship between microecology, hypothyroidism and iodine-131 treatment, probiotics in the prevention of hypothyroidism and iodine-131 treatment The link between the effects of side effects remains unclear. Therefore, the team will conduct a correlation study between microbes and hypothyroidism, iodine-131 treatment.
