Treatment Options for Papillary Thyroid Cancer – Surgery, Radioactive Iodine, Targeted Therapies, and More
Overview of Papillary Thyroid Cancer
Papillary thyroid cancer (PTC) is the most common type of thyroid cancer, accounting for about 80% of all thyroid cancer cases. It typically affects individuals between the ages of 30 and 50, and is more commonly found in women than in men.
PTC originates in the follicular cells of the thyroid gland and is characterized by the presence of papillary structures when viewed under a microscope. The cancer cells tend to grow slowly and are often well-differentiated, meaning they resemble normal thyroid cells to some extent.
Symptoms of Papillary Thyroid Cancer
- Presence of a lump or nodule in the neck
- Difficulty swallowing or breathing
- Hoarseness
- Neck pain
- Enlarged lymph nodes in the neck
Diagnosis of Papillary Thyroid Cancer
Diagnosis of PTC typically involves a physical examination, imaging tests such as ultrasound and CT scans, as well as a biopsy to confirm the presence of cancerous cells. Blood tests to measure thyroid hormone levels and thyroid function may also be performed.
Treatment of Papillary Thyroid Cancer
The treatment approach for PTC often involves surgery to remove the cancerous thyroid tissue, known as a thyroidectomy. Depending on the extent of the disease and the presence of metastasis, additional treatment modalities such as radioactive iodine therapy, targeted drug therapies, and radiation therapy may be recommended.
Prognosis of Papillary Thyroid Cancer
PTC has a generally favorable prognosis, with a high overall survival rate. The 5-year relative survival rate for localized PTC is estimated to be around 99%. However, the prognosis can vary depending on the stage of the cancer at diagnosis and the response to treatment.
