Preferred Medicine Announces Presentation on Machine Learning-based Early Cancer Detections with Blood miRNAs at American Society of Clinical Oncology 2021

BURLINGAME, Calif. - June 3, 2021 - (updated on June 13th, 2021)

Preferred Medicine Inc., a joint venture between Preferred Networks Inc. (PFN) and Mitsui & Co., Ltd. (Mitsui), announced today that a joint research on machine learning-based cancer detections with circulating microRNA (miRNA) profiles in the blood will be presented at the 2021 annual meeting of American Society of Clinical Oncology (ASCO), to be held on June 4 - 8, 2021. The joint research was conducted in the U.S. by Preferred Networks America, Inc., Preferred Medicine and National Cancer Center Japan.

In the joint research, blood samples from patients with breast, colorectal, lung, stomach and pancreatic cancers, and non-cancer volunteers were collected through National Cancer Center Japan and other medical institutions. The entire miRNA expression profile was obtained with a next-generation sequencer and used to train machine learning models for cancer detection. The results will be presented at the ASCO poster session in the Developmental Therapeutics—Molecularly Targeted Agents and Tumor Biology track on June 4, 2021.
