Thyroid cancer (TC) is the most common endocrine tumor, with an annual incidence of 3.4% all cancers. An increasing described in recent years probably due to improved diagnostic techniques. It crucial identify type and stratify its risk. Among TC, papillary thyroid indolent best overall prognosis. However, there are some aggressively behaving TC that need be detected treated early. These includ...
Thyroid cancer accounts for approximately 3% of all new diagnoses per year globally.1 Papillary thyroid carcinoma (PTC) is the most common type, followed by follicular (FTC).1 Recently, simultaneous appearance different histological variants in same patient has been reported, being called combined pattern cancer, mixed tumors, hybrid tumors or compound gland.2 Epidemiologically, reported less t...
Background and purpose: Multinodular goiter is a benign enlargement of thyroid gland and papillary thyroid carcinoma is the most common type of thyroid cancer. Today, immunohistochemical markers can be used in diagnosis and prognosis of tumors. The aim of this study was to compare the expression of CD117 in multinodular goiter and papillary thyroid carcinoma and its association with prognostic...
In Taiwan, thyroid cancer is the most common endocrine gland malignancy and the incidence of thyroid cancer has increased four-fold in the past two decades. Fine-needle aspiration is an accurate and cost-effective method of evaluating thyroid nodules and has been the gold-standard diagnostic tool for thyroid tumors in Taiwan since the 1980s. This article reviews the history, current practice, r...
Several oncogenes and tumor-suppressor genes are involved either as early or late event in thyroid gland carcinogenesis. Human FHIT (fragile histidine triad) gene is highly conserved gene whose loss of function may be important in the development and/or progression of various types of cancer. We undertook this study to analyze FHIT and p53 gene status in different benignant and malignant thyroi...
Laboratory procedures available for aid in the differential diagnosis of thyroid tumors include serum hormone measurements, a variety of thyroid scanning procedures, ultrasonography and needle biopsy of the thyroid. Serum calcitonin measurements appear to be highly reliable indicators of the pres ence of medullary carcinoma of the thyroid gland. Thyroid scans using isotopes of iodide or techne...
