Jun 15, 2023 · The ccLS is 3 (intermediate likelihood of ccRCC), with a differential diagnosis of oncocytoma based on the presence of SEI. On the basis of the patient’s age, comorbidities, and probable need for radical rather than partial nephrectomy, the patient was actively surveilled with stability of the mass over 18 months of follow-up.

A clear cell likelihood score (ccLS) based on a Likert scale (1-very unlikely, 2-unlikely, 3-equivocal, 4-likely, and 5-very likely) for interpretation of mpMRI examinations has been reported as an approach to noninvasively detect ccRCC.

Dec 14, 2021 · The clear cell likelihood score (ccLS) derived from multiparametric MRI is useful in noninvasively identifying the clear cell subtype, the most common and aggressive form of kidney cancer. Herein, a review of the ccLS is presented, including a step-by-step guide for image interpretation and additional guidance for its implementation in clinical ...

Feb 19, 2025 · Early characterization of subcentimeter (≤1 cm) renal lesions is crucial for effective clinical management. This study aims to validate the diagnostic performance of the multiparametric MRI (mpMRI) clear cell likelihood score (ccLS) category in diagnosing subcentimeter clear cell renal cell carcinoma (ccRCC).

Key points: • The positive predictive value of the clear cell likelihood score (ccLS) for detecting clear cell renal cell carcinoma was 5% (ccLS1), 6% (ccLS2), 35% (ccLS3), 78% (ccLS4), and 93% (ccLS5). Sensitivity of ccLS ≥ 4 and specificity of ccLS ≤ 2 were 91% and 56%, respectively.

The clear cell likelihood score (ccLS) system was devised in recent years to create a systematic approach for assessing the MRI features of SRMs and assigning a ccRCC likelihood score (3–6). Comprehensive SRM assessment includes integrating many contributing imaging features, which can make inter-pretation challenging.

Calculate the Clear Cell Likelihood Score (ccLS) for solid renal masses on MRI to assess the risk of clear cell renal cell carcinoma (ccRCC).

The ccLS is a 5-tier classification that denotes the likelihood of a mass representing a clear cell carcinoma: 1, very unlikely; 2, unlikely; 3, equivocal; 4: likely; and 5, highly likely. First, reviewer must exclude the presence of macroscopic fat (i.e. ccLS is not applicable to masses with macroscopic fat), which would be diagnostic of ...
