"Why is TSH Level Elevated After a Partial Thyroidectomy for Thyroid Cancer?"

TSH and Its Elevation After Thyroid Cancer Hemithyroidectomy

TSH stands for Thyroid Stimulating Hormone. Thyroid cancer hemithyroidectomy refers to the surgical removal of half of the thyroid gland. An elevated TSH level post-surgery may be attributed to postoperative hypothyroidism, tumor recurrence, or a stress response. It is recommended to seek targeted treatment under the guidance of a physician.

1. Postoperative Hypothyroidism

After hemithyroidectomy for thyroid cancer, the surgical procedure may affect thyroid hormone secretion, leading to insufficient production and thus an elevated TSH level. Treatment options include taking levothyroxine sodium tablets or thyroid tablets as prescribed by a doctor.

2. Tumor Recurrence

If cancer cells are not completely removed during hemithyroidectomy or if postoperative care is inadequate, leading to new lesions, tumor recurrence may occur. This can stimulate the body to produce more TSH, resulting in an elevated TSH level post-surgery. Chemotherapy, radiotherapy, and targeted therapy can be considered to control disease progression.

3. Stress Response

Post-hemithyroidectomy, patients with thyroid cancer may experience a stress response due to factors such as weakness, excessive psychological pressure, or financial strain. This can lead to an elevated TSH level. The stress response can be alleviated through proper rest and psychological counseling.

4. Other Factors

Excessive administration of radioactive iodine-131 after surgery may damage thyroid tissue cells, resulting in an elevated TSH level. It is recommended to avoid high-dose exposure of iodine-131 in a single session during treatment. If patients experience an elevated TSH level post-hemithyroidectomy for thyroid cancer, they should consult a specialist in oncology at a reputable hospital for further assessment through blood tests and ultrasounds.
