The CUT score is a new cancer risk score for thyroid nodules suitable in any clinical setting.
The CUT is an acronym indicating Clinical, Ultrasonographic and Thyroid cytology aspects of a thyroid nodule. The CUT score has been created to help clinicians with thyroid nodule preoperative malignancy risk assessment.
This tool is intentionally developed on easily avalaible clinical data in order to allow physicians to apply the ‘‘CUT’’ score in any clinical setting using basic US technology.

In the CUT score, the sum of each clinical (C) and/or ultrasonographic (U) suspicious feature results in the C+U sum, ranging from 0 to 10. This sum along with the five-tiered score of the fine-needle aspiration results (T = 1–5) determines the final ‘‘CUT’’ score of the TN.

The C+U sum of the CUT score:
helps to select thyroid nodules requiring fine-needle aspiration (e.g., the thyroid nodule with the highest C+U score in a multinodular goiter)
when the thyroid cytology (T) is avalaible, allows to assess the risk of malignancy of the thyroid nodule in the final CUT score.

The CUT score is designated exclusively for medical use and is not intended to be directly used by the patient to take any medical decision without a doctor’s advice.

It has been created by the work of endocrinologists operating in the Policlinico Gemelli’s Division of Endocrinology. It’s a medical application derived from the following published studies:
