Despite the aforementioned study by Choschzick et al., other research efforts in this field also aim to detect ki-67 using deep learning models in breast cancer or cervical intraepithelial lesions, or to develop a virtual ki-67-stained slide based solely on regular hematoxylin/eosin staining of squamous cell carcinomas [73,74,75]. The gene discussed is MKI67; the disease is breast carcinoma.
