Prognostic Significance of Fine-Needle Aspiration Cytology Features in Papillary Thyroid Carcinoma
The purpose of this study is to investigate the relationship between prognosis and fine needle aspiration cytology character of papillary thyroid cancer.
Papillary thyroid carcinoma is the most common thyroid malignancy worldwide. The influence of clinicopathologic features on prognosis has been examined, but the relationship between cytologic features obtained by fine-needle aspiration (FNA) and prognosis has been minimally studied. We retrospectively studied the cytologic features with computerized morphometry in 83 patients with usual-type papillary thyroid cancer and followed them for more than 10 years except for one with metastasis at diagnosis. The cytologic features of FNA and recurrence of cancer were examined statistically.

Medical and Biotech [MESH] Definitions
Tumors or cancer of the THYROID GLAND.
Autoantibodies that bind to the thyroid-stimulating hormone (TSH) receptor (RECEPTORS, THYROTROPIN) on thyroid epithelial cells. The autoantibodies mimic TSH causing an unregulated production of thyroid hormones characteristic of GRAVES DISEASE.
A condition characterized by the presence of rudimentary THYROID tissue at the base of the TONGUE. It is due to failed embryonic development and migration of thyroid tissue to its normal location. The lingual thyroid usually cannot maintain adequate hormone production thereby resulting in HYPOTHYROIDISM.
A hypermetabolic syndrome caused by excess THYROID HORMONES which may come from endogenous or exogenous sources. The endogenous source of hormone may be thyroid HYPERPLASIA; THYROID NEOPLASMS; or hormone-producing extrathyroidal tissue. Thyrotoxicosis is characterized by NERVOUSNESS; TACHYCARDIA; FATIGUE; WEIGHT LOSS; heat intolerance; and excessive SWEATING.
Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE.
Thyroid nodules are common (prevalence of 12.7% in women), but are malignant in only 5% of cases. International experts agree that a preliminary cytological examination by fine needle aspi...
The purpose of this study is to evaluate how common gene mutations are in benign and malignant thyroid lesions.
Needle size from22 to 25 were used for fine needle aspiration of palpable breast lumps. In this study we choose one, randomly, and fallow the result of cytologic evaluation regarding speci...
RATIONALE: Measuring changes in the thyroid gland after radiation exposure may help doctors learn about the long-term effects of radiation exposure and help the study of thyroid cancer and...
RATIONALE: Gathering information about patients with thyroid cancer or thyroid nodules may help the study of thyroid cancer in the future. PURPOSE: This study is gathering information and...
Thyroid fine needle aspiration (FNA) is a safe, cost effective, and relatively accurate method for guiding the initial management of a thyroid nodule. The popularity of thyroid FNA is reflected in the...
OBJECTIVES: To retrospectively compare the accuracy of fine-needle aspiration (FNA) and core-needle biopsy (CNB) for the diagnosis of thyroid malignancy METHODS: We evaluated the results of FNA and CN...
The Bethesda System for Reporting Thyroid Cytopathology is largely based on data from adult studies. Although thyroid nodules in children are rare, the rate of malignancy is high. The authors' aim was...
Objectives The purpose of this study was to determine the importance of nondiagnostic fine-needle aspiration biopsy results for post-thyroidectomy bed lesions in patients with thyroid cancer. Methods...
PURPOSE: Our institution routinely utilizes needle core biopsy (NCB), instead of fine needle aspiration, in the evaluation of pediatric thyroid nodules. This practice initially arose from limited cyto...
