Clinical Approach of thyroid nodule

Ch. Daumerie Published in the journal : March 2016 Category : Session Pathologie Thyroïdienne

The new published guidelines on the management of the thyroid nodule have greatly improved the management of the disorder. Despite current guidelines, thyroid nodule management remains controversial and varies in different continents and countries. A difference between USA and Europe is in the iodine status and explains why the thyroid scintigraphy is more often prescribed in Europe than in USA. New recommendations are often applied in function of the easy access to complementary exams, the performance of other physicians, their personal experience and their medical habits. It is the reason why the guidelines are not always strictly followed.

The role of ultrasound in the management of thyroid nodules: the TI-RADS classification

D. Millon, E. Coche Published in the journal : March 2016 Category : Session Pathologie Thyroïdienne

Ultrasound plays a key role in the management of thyroid nodules, from diagnosis to follow-up. The Thyroid Imaging Reporting And Data System (TI-RADS) classification is a standardized system for analyzing and reporting thyroid ultrasound data in order to improve nodule management. This 6-grades score is based on ultrasound criteria (shape, contour, aspect, and structure) and aimed at categorizing and depicting carcinomas in a simple and reproducible way. Based on operator-dependent ultrasound examination, the TI-RADS classification has both strengths and limitations.

THE ROLE OF CYTOLOGY IN THE MANAGEMENT OF THYROID NODULES

A. Camboni Published in the journal : March 2016 Category : Session Pathologie Thyroïdienne

Cytology plays a key role in the management of thyroid nodules. This technique may prove to be a valuable diagnostic tool for differentiating benign lesions from malignant ones, enabling us to better select those nodules that warrant surgery. The middle cytology liquid allows us to complete this process by adding immunocytochemical or molecular biology tests, as necessary. In the event of nodules presenting atypia of undetermined significance, recent studies have revealed that genome sequencing for detecting BRAF or RAS mutations may permit to assess the risk for malignancy of these thyroid nodules. It should yet be mentioned that only a close collaboration with the clinicians in charge of the patient, in addition to a sound correlation with clinical-radiological data, allows the cytological thyroid examination to prove well-performing.
