A deep learning system for prostate cancer diagnosis and grading in whole slide images of core needle biopsies

Abstract: Gleason grading, a risk stratification method for prostate cancer, is subjective and dependent on experience and expertise of the reporting pathologist. Deep Learning (DL) systems have shown promise in enhancing the objectivity and efficiency of Gleason grading. However, DL networks exhibit domain shift and reduced performance on Whole Slide Images (WSI) from a source other than training data. We propose a DL approach for segmenting and grading epithelial tissue using a novel training methodology that learns d… Show more

“…Jiang et al categorize the implementation of computational pathology in oncology into five purposes, which are tumor diagnosis, subtyping, grading, staging, and prognosis [30]. Thus, we can find applications of these five purposes for breast cancer [30,[105][106][107][108], lung cancer [30,[109][110][111], colorectal cancer [30,[112][113][114][115], gastric cancer [30,116,117], prostate cancer [30,118,119], and thyroid cancer [30,120,121]. Another set of applications of computational pathology lies in the automatic analysis for the identification of rejection in organ transplantation.…”

“…Both CNNs attained similar results with mean and standard deviation accuracy of 61.17±7for AlexNet and for GoogleNet results of 60.9±7.4. Other studies adopted more sophisticated approaches as in Singhal et al study (Singhal et al 2022). A multi step iterative system is developed where pathologists first annotate the images, then active learning-based data labeling is performed on datasets.…”

“…As for the global AI competition, the Prostate cANcer graDe Assessment (PANDA) challenge, a group of AI Gleason grading algorithms developed during a global competition generalized well to intercontinental and multinational cohorts with pathologist-level performance [10]. Other works [23,[28][29][30][31][32][33][34] have also looked into developing deep learning algorithms to classify prostate cancer Gleason scores based on histopathological images.…”
