Brief Summary:
Thyroid cancer (TC) is the most common endocrine malignancy. The association between inflammation and cancer is well established but the association between thyroiditis (inflammation of thyroid gland) especially Hashimoto's thyroiditis (HT) and thyroid cancer remains controversial. Chronic inflammation leads to a repeated cycle of cellular damage and subsequent healing which contributes to inappropriate cell proliferation and subsequent neoplastic transformation. One of the most common forms of Thyroiditis is Hashimoto's thyroiditis which is a chronic autoimmune inflammatory disease affects almost 5% of the population and is more common in women. For the first time, Dailey and Lindsay reported in 1955 an increased association between Hashimoto's Thyroiditis (HT) and thyroid cancer. They reported 35 thyroid cancers in 278 patients with Hashimoto's Thyroiditis, a prevalence of 17.7% which they considered higher than the general population . Since then, various studies have been done, some studies have reported an increased risk of malignancy in Hashimoto's thyroiditis; others have failed to find an association. Most of the studies that have been done to identify the association between Hashimoto's thyroiditis and thyroid cancer are retrospective. The purpose of this pilot case-control study is to identify the association of Hashimoto's thyroiditis and thyroid cancer, to determine if the presence of Hashimoto's thyroiditis has any affect on the complication of thyroidectomy and prognostic factors of thyroid cancer.
Detailed Description:
AIM1: To identify the association between Hashimoto's Thyroiditis and thyroid cancer by comparing the prevalence of thyroid cancer in patients with Hashimoto's Thyroiditis and patients without Hashimoto's Thyroiditis who undergoing Thyroidectomy for a variety of indications in UTMB in 12 months period of the study.
AIM2: Compare Ultrasound (US) characteristics preoperatively in two groups of patients with thyroid cancer and Hashimoto's thyroiditis and patients with thyroid cancer but without Hashimoto's thyroiditis.
AIM3: compare prognostic factors including tumor diameter, vascular and capsular invasion, extra thyroid invasion, lymph node metastasis, distant metastasis in two groups of patients including patients with thyroid cancer and Hashimoto's thyroiditis and patients with thyroid cancer but without Hashimoto's thyroiditis.
AIM4: Compare the complication of surgery in patients with thyroid cancer and Hashimoto's Thyroiditis and patients with thyroid cancer but without Hashimoto's thyroiditis.
AIM5: Compare inflammatory factors in two group of patient with thyroid cancer and Hashimoto's Thyroiditis and patients with thyroid cancer but without Hashimoto's thyroiditis.
Coordinator in the ear, nose and throat (ENT) clinic will notify the assigned investigator about any patient admitted to UTMB for thyroidectomy. The investigator will meet and interview the patient to obtain the consent and fill out a data collection sheet which will include demographic data, history of thyroid disease, history of thyroid medications, history of radiotherapy of head and neck or radioactive iodine therapy, family history of thyroid disease or thyroid cancer. Patients meeting the inclusion criteria will be given the opportunity to participate in the study. All patients will have blood drawn. Blood samples will be stored in Endocrinology lab to measure Anti-TPO, Ca, PTH and inflammatory factors at the end of study. A chart review of all enrolled patients will be performed to obtain details of the preoperative thyroid U/S characteristics including echogenicity, texture, calcification, vascularity and TSH and Free T4 level. Postoperative histopathology evaluation will be done by a pathologist experienced in thyroid pathology. The diagnosis of Hashimoto's thyroiditis (HT ) will be made based on histopathology finding and AntiTPO level. The histopathology criteria for Hashimoto's thyroiditis (HT) must be seen in a normal region of the thyroid gland, distinct from the site of thyroid cancer. UTMB Subjects will be divided to two groups, subjects with Hashimoto's Thyroiditis and subjects without Hashimoto's Thyroiditis (control group).The prevalence of thyroid cancer will be compared in these two groups.
