Ull block H E slides from 1013 colorectal carcinomas that had been (largely) part of a previously published collective were rescreened on full block slides at the starting of this study [4], where the carcinomas had been re-classified in accordance with all the subtypes listed inside the 2019 WHO classification of tumors on the digestive system. Tumors that had been not part of the preceding cohort but added for the collective had been classified as described previously [4]. The final investigated cohort comprised 1002 colorectal adenocarcinomas of many subtypes that showed no morphologic capabilities suggestive of a neuroendocrine carcinoma (Figure 1). Eleven colorectal cancers had been diagnosed as MANECs on complete block slides as they showed adenocarcinomas that were mixed using a tumor element 30 that was morphologically suggestive of a neuroendocrine carcinoma and that expressed synaptophysin (and Chromogranin A), in accordance with current WHO suggestions (Figure 2). These 11 colorectal MANECs had been applied as a statistical control group for additional analyses.Cancers 2021, 13, xCancers 2021, 13,5 of4 Cymoxanil Fungal ofFigure 1.
