The application of artificial intelligence in pathology reveals new insights into endometrial cancer diagnostics
December 16, 2022
Research at the pathology department of Leiden University Medical Center (LUMC) shows the power of artificial intelligence (AI) applied to microscopic images of endometrial cancer. Dr. Tjalling Bosse’s group offers new insights that could improve the diagnosis and treatment of uterine cancer. Their results have been published in The Lancet’s digital health.
Endometrial cancer is the most common cancer of the gynecological tract. Both clinical trials and translational research are conducted at the LUMC to improve care for these patients. In recent years, the LUMC has taken a leading role in the development of a new cancer classification system based on molecular alterations, which has resulted in four subtypes of endometrial cancer. Would it be possible to predict these molecular classes, based only on microscope images?
Thousands of images
Bosse and colleagues applied artificial intelligence on microscopic images of thousands of endometrial cancer images from patients who participated. His team developed a model that reliably predicts the four molecular classes of endometrial carcinomas based on an image of a stained microscope slide (hematoxylin and eosin), which is the standard histological stain used in diagnostics for assessing tumor classification and histological subtype.
This model was not “a black box,” but through reverse engineering the researchers were able to show which features of the image were relevant to its predictions. The model has provided the team with important new insights that can be used in future studies to further improve the diagnostics, prognosis and management of endometrial cancer patients.
Emerging application of AI
“The application of AI in pathology is emerging. In this project, we studied the morphology of tumors that shared the same molecular alteration to better understand the effect these changes have on tumor appearance. With this work, the computer model it directed us to the areas inside and outside the tumor that are important,” notes Bosse.
“In cancer diagnostics, the number of variables (molecular, tumor morphology, patient data) has increased exponentially and made predicting patient prognosis more complex. Through training unbiased AI models, AI predictions they can also teach pathologists in return, for example, by identifying new morphological parameters details on microscope slide images with prognostic value,” says Sarah Fremond.
