Deep Learning Benefits Stomach Cancer Patients
In stomach cancer, deep learning was found to help predict the occult peritoneal metastasis, stated a new study published in the JAMA Network Open.
Stomach cancer, or gastric cancer, is a common gastrointestinal malignancy. Peritoneal //metastasis occurs in a majority of patients with advanced stomach cancer and is considered as an aggressive disease with poor outcomes.

Patients with peritoneal metastasis are typically not eligible for curative surgery. Therefore, preoperative detection and diagnosis of peritoneal metastasis are critical to inform treatment decision-making and avoid unnecessary surgery.

The study was conducted by Dr. XIE Yaoqin's group from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences, Dr. LI Ruijiang from Stanford University, Dr. LI Guoxin from Nanfang Hospital, and Dr. ZHOU Zhiwei from Sun Yat-sen University Cancer Center.

The researchers developed a deep learning model called Peritoneal Metastasis Network (PMetNet) to predict clinically occult peritoneal metastasis using preoperative computed tomography (CT) images in patients with stomach cancer.

Dr. JIANG Yuming from Stanford University, one co-first author of this study, explained that the proposed deep learning model may serve as a reliable noninvasive tool for the early identification of patients with clinically occult peritoneal metastasis.

"It can also inform individualized preoperative treatment decision-making and may avoid unnecessary surgery and complications," said Ph.D. candidate LIANG Xiaokun from SIAT, the other co-first author.
