Singapore researchers develop AI tool for liver cancer recurrence

The TIMES system predicts risk with 82% accuracy.

Researchers from A*STAR Institute of Molecular and Cell Biology (A*STAR IMCB) and Singapore General Hospital (SGH) have developed an AI-powered scoring system to predict the recurrence of hepatocellular carcinoma, the most common form of liver cancer.

The system, entitled the Tumour Immune Microenvironment Spatial (TIMES) score, predicts recurrence risk with about 82% accuracy by analysing the precise spatial distribution of ‘natural killer’ cells and five specific genes in liver tumour tissues.

“In Singapore, up to 70% of liver cancer patients experience recurrence within five years,” Joe Yeong, Principal Investigator at A*STAR IMCB and Principal Investigator, Department of Anatomical Pathology, SGH, said.

The researchers validated the TIMES system using samples from 231 patients across five hospitals.

They have also made the technology accessible via a free web portal for research use, with plans to integrate TIMES into routine clinical workflows.

Moreover, the team is planning further validation studies at SGH and the National Cancer Centre Singapore, scheduled to start later this year.

Discussions are ongoing with diagnostic partners to develop the system into a clinically approved diagnostic test kit.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
