[Non-invasive follicular thyroid neoplasm with papillary-like nuclear features].
Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced to cover a group of noninvasive encapsulated follicular-patterned thyroid lesions with very low malignant behavior. This nomination may have a great impact on the incidence of thyroid malignancy and the practice for endocrine pathologists. To demonstrate the proportion of the thyroid follicular ...
متن کاملSubclassification of Follicular Neoplasms Recommended by the Japan Thyroid Association Reporting System of Thyroid Cytology
Background. The Japan Thyroid Association recently published guidelines for clinical practice for the management of thyroid nodules, which include a diagnostic system for reporting thyroid fine needle aspiration cytology. It is characterized by the subclassification of follicular neoplasms, which is different from other internationally accepted reporting systems. Materials and Methods. This stu...
متن کاملHighly accurate diagnosis of cancer in thyroid nodules with follicular neoplasm/suspicious for a follicular neoplasm cytology by ThyroSeq v2 next-generation sequencing assay.
BACKGROUND Fine-needle aspiration (FNA) cytology is a common approach to evaluating thyroid nodules, although 20% to 30% of FNAs have indeterminate cytology, which hampers the appropriate management of these patients. Follicular (or oncocytic) neoplasm/suspicious for a follicular (or oncocytic) neoplasm (FN/SFN) is a common indeterminate diagnosis with a cancer risk of approximately 15% to 30%....
متن کاملImpact of NRAS Mutations on the Diagnosis of Follicular Neoplasm of the Thyroid
Background. Most patients with a preoperative diagnosis of thyroid follicular neoplasm (FN) undergo diagnostic surgery to determine whether the nodule is benign or malignant. Point mutations at NRAS codon 61 are the most common mutations observed in FN. However, the clinical significance of NRAS mutation remains unclear. Methods. From 2012 to 2013, 123 consecutive patients undergoing thyroidect...
متن کاملNoninvasive follicular thyroid neoplasm with papillary-like nuclear features: a single-institutional experience in Japan.
Noninvasive encapsulated follicular variant of papillary thyroid carcinoma (PTC) was reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). To date, no studies on NIFTP have been reported in Japan. This study aimed to evaluate the clinical, cytological, and pathological findings of 54 cases of NIFTP from a single center in Japan, and compare them w...
