ROMs for other categories were: Thy1\/T1 (9% vs 6.7%), Thy2\/T2 (5.1% vs 0%), Thy3\/T3 (17.5% vs 18.4%) and Thy4\/T4 (73.3% vs 100%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The proportion of cases in each RCPath Thy category has remained relatively stable during the 9-year study period, with the exception of the Thy3a category, which has increased over time. This finding is in line with other more recent reports in the literature and the proportion of T3 cases in the CNB group. The proportion of Thy2\/Thy2c cases has also reduced over time, reflecting a local change in the triaging protocol for probable benign lesions.
