Introduction:

The thyroid nodule is a frequent health problem, which has increased with the increased availability of diagnostic ultrasound in primary care. An adequate system of stratification of the risk of malignancy would reduce the overload of health systems, especially in the Cuban context. A review was carried out in the Cumed, Lilacs, PubMed / MEDLINE, Web of Science and Scopus bases, with the descriptors: thyroid nodule, ultrasonography and clinical practice guideline as subject; In Spanish and English. The therapeutic guidelines published in the last 10 years were selected, which would provide a stratification system of risk of malignancy of the thyroid nodules by ultrasound.

Objectives:

To identify the stratification systems of the risk of malignancy of nodular thyroid lesions, based on the ultrasound examination; recognize their coincidences, divergences and value their implementation in the Cuban context.

Development:

All systems recognize the same ultrasound risk characteristics: hypo-echoic solid nodules, irregular or spiculated margins, taller than wide (anteroposterior diameter greater than transverse) and the presence of micro calcifications; although none of them alone is pathognomonic for thyroid cancer. However, they use different nomenclatures and number of stages and most importantly, the decision to perform or not a fine needle biopsy differs depending on which one is used.

Conclusions:

It is necessary to apply in Cuba some of these systems in an extended way and even better, generate your own, based on Cuban patients.
