Predicting malignancy in thyroid nodules: molecular advances.
Over the last several years, a clearer understanding has developed of the genetic alterations underlying thyroid carcinogenesis. This knowledge can be used to tackle 1 of the challenges facing thyroidologists: management of the indeterminate thyroid nodule. Despite the accuracy of fine-needle aspiration cytology, many patients undergo surgery to diagnose malignancy and better diagnostic tools a...
متن کاملThyroid Nodules with Macrocalcification: Sonographic Findings Predictive of Malignancy
PURPOSE To analyze which sonographic features of thyroid nodules with macrocalcifications were predictable of thyroid malignancy. MATERIALS AND METHODS We reviewed sonographic findings of 854 macrocalcified thyroid nodules in patients who underwent fine needle aspiration biopsy between December 2009 and January 2011. There were 171 non-diagnostic aspirations, 34 nodules with category 3, 4, 5 ...
متن کاملClassification and Regression Tree (CART) Techniques
In certain research studies development of a reliable decision rule, which can be used to classify new observations into some predefined categories, plays an important role. The existing traditional statistical methods are inappropriate to use in certain specific situations, or of limited utility, in addressing these types of classification problems. There are a number of reasons for these diff...
متن کاملMalignancy Risk Assessment in Patients with Thyroid Nodules Using Classification and Regression Trees
Purpose. We sought to investigate the utility of classification and regression trees (CART) classifier to differentiate benign from malignant nodules in patients referred for thyroid surgery. Methods. Clinical and demographic data of 271 patients referred to the Sadoughi Hospital during 2006-2011 were collected. In a two-step approach, a CART classifier was employed to differentiate patients wi...
متن کاملPredicting malignancy in thyroid nodules: feasibility of a predictive model integrating clinical, biochemical, and ultrasound characteristics
BACKGROUND Although the majority of thyroid nodules are benign the process of excluding malignancy is challenging and sometimes involves unnecessary surgical procedures. We explored the development of a predictive model for malignancy in thyroid nodules by integrating a combination of simple demographic, biochemical, and ultrasound characteristics. METHODS Retrospective case-record review. We...
