PALO ALTO, Calif.--(BUSINESS WIRE)-- Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, announced today it will present new data at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting from June 3-7 in Chicago. Among the 19 abstracts are oral presentations highlighting the use of real-world data to identify resistance to early treatment in advanced breast cancer and the use of enhanced biomarker analysis to evaluate progression-free survival data in metastatic breast cancer therapy.

“We look forward to sharing an array of robust data at ASCO that demonstrate the utility of our blood tests to help healthcare professionals optimize care for patients at all stages of the disease—from detecting early-stage cancers to identifying the presence of residual disease and delivering insights that inform treatment to improve outcomes,” said Helmy Eltoukhy, Guardant Health co-CEO. “We’ll be presenting data from retrospective and real-world analyses that show how blood-based tests provide critical insights at every step of a patient’s treatment journey, and analytics that contribute to the broader scientific community’s understanding of some of the most challenging cancers.”
