We observed highly significant differences regarding the frequency of TROP2‐positive CRCs between MSS (22.3%) and microsatellite unstable CRCs (9.7%), as TROP2 expression was significantly more frequent in MSS carcinomas (p < 0.001) and comparatively rare in microsatellite unstable CRC (Figure 2). The gene discussed is TACSTD2; the disease is colorectal carcinoma.
