Tempus to Present Six Abstracts Accepted at the 2026 Connective Tissue Oncology Society Annual Meeting

CHICAGO--(BUSINESS WIRE)--Tempus AI, Inc. (NASDAQ: TEM) today announced that six abstracts (including three oral presentations) will be presented at the 2026 Connective Tissue Oncology Society (CTOS) Annual Meeting taking place November 18–21 in Seoul. At this year’s meeting, Tempus will present clinical research on rare mesenchymal tumors, highlighting how advances in molecular diagnosis and classification are unlocking new treatment options.

This research leverages Tempus’ expansive, de-identified multimodal library, which includes a cohort of 45,085 real-world patients across 615 rare and ultra-rare cancer types. Within this comprehensive repository, sarcomas are among the most well-represented cancer types. This deep data foundation directly enabled the clinical findings being presented at CTOS, demonstrating the power of comprehensive multimodal profiling—including DNA matched tumor/normal sequencing, whole transcriptomic analysis, and digital pathology informatics—to reveal actionable insights.

“In rare diseases, such as sarcoma, small patient datasets make uncovering insights exceptionally challenging, which is where Tempus’ robust dataset brings critical value," said Ezra Cohen M.D., Chief Medical Officer of Oncology at Tempus. “Importantly, Tempus is dedicated through its Orphan Disease Program to providing solutions to the inherent barriers in rare cancers, and to helping physicians develop and tailor therapies more precisely.”
