Malignancy 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 کاملRisk of malignancy in fine-needle aspiration biopsy in patients with thyroid nodules.
INTRODUCTION Fine-needle aspiration biopsy (FNAB) is the cornerstone of thyroid nodule evaluation. In most cases, FNAB can discriminate between benign and malignant disease. In other cases, it is only indicative of malignancy and the results are considered "suspicious". In Denmark, thyroid FNAB results are categorised into six groups: "inadequate", "cystic", "inconclusive", "benign", "suspiciou...
متن کاملPreoperative Prediction of the Risk of Malignancy in Thyroid Nodules
Objective: This study aimed to propose a formula for predicting the biological nature of thyroid nodules, thus helping in clinical decision making and avoiding unnecessary surgery. Patients and methods: Prospective, longitudinal and observational study was conducted on 400 patients submitted to primary thyroid surgery at the Department of Surgery, University of Pisa, Italy, between April 1st an...
متن کاملRisk of Malignancy in Thyroid Nodules 4 cm or Larger
BACKGROUND Several authors have questioned the accuracy of fine-needle aspiration cytology (FNAC) in large nodules. Some surgeons recommend thyroidectomy for nodules ≥4 cm even in the setting of benign FNAC, due to increased risk of malignancy and increased false negative rates in large thyroid nodules. The goal of our study was to evaluate if thyroid nodule size is associated with risk of mali...
متن کاملthe evolution of a malignancy risk prediction model for thyroid nodules using the artificial neural network
background: clinically frank thyroid nodules are common and believed to be present in 4% to 10% of the adult population in the united states. in the current literature, fine needle aspiration biopsies are considered to be the milestone of a model which helps the physician decide whether a certain thyroid nodule needs a surgical approach or not. a considerable fact is that sensitivity and specif...
