The authors previously reported a combination of a four\u2010risk factor model highly predictive of neoplasia and malignancy that included four cytologic features and nodule size. However, that model was based on a single cytopathologist (CP) review. The current study assessed the reproducibility of previous findings among several CPs in a larger separate patient cohort, correlated with molecular studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Four CPs independently evaluated cytologic features of 173 surgically confirmed OCP (24 AUS, 149 FN). Nodule size was recorded separately and incorporated into risk factor scores. A subset of 80 cases underwent molecular testing with Afirma or ThyroSeq. Univariable and multivariable logistic regression and ROC analyses were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Interobserver agreements were strong for high cellularity, moderate for isolated single cells, and poor for absent colloid and anisonucleosis. Risk factor scores demonstrated strong agreement, high specificity (77%\u201392%) and low sensitivity (6%\u201322%). Pathologist agreement did not better predict neoplasm or malignancy. Afirma and ThyroSeq molecular tests had similar performances with overall sensitivity, specificity, and false\u2010negative rates of 86%, 35%, and 13%\u201317%, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Cytologic evaluation of OCP was limited by wide interobserver variability and inconsistent associations with outcomes. Agreement of CPs on presence of specific cytologic features did not enhance prediction of neoplasm or malignancy. Molecular testing provided more objective performance displaying high sensitivity; however, specificity was low and FNR was elevated. Clinicians should be made aware of the greater limitations associated with cytology and molecular test results of OCP compared to those reported for their nononcocytic counterparts.<\/jats:p>\n
