Tethis and Sheba Medical Center announce research collaboration to advance AI-powered liquid biopsy in rectal cancer

"Working with Sheba represents a significant step in expanding the applications of our liquid biopsy platform," states Dr. Holger Neecke, CEO of Tethis. "Our See.d instrument, combined with our nanocoated SmartBioSurface slides, enables standardized preparation of cytology specimens containing immune and tumor cells, suited for sequential multiplexing and interpretation with artificial intelligence, while collecting plasma for cell free DNA analysis."  "Working with Sheba represents a...

"Working with Sheba represents a significant step in expanding the applications of our liquid biopsy platform," states Dr. Holger Neecke, CEO of Tethis. "Our See.d instrument, combined with our nanocoated SmartBioSurface slides, enables standardized preparation of cytology specimens containing immune and tumor cells, suited for sequential multiplexing and interpretation with artificial intelligence, while collecting plasma for cell free DNA analysis." 

"This collaboration exemplifies Sheba's commitment to advancing precision medicine through innovative technologies," says Prof. Iris Barshack, Head of the Pathology Institute. "By combining Tethis' cutting-edge liquid biopsy platform with our extensive clinical expertise in oncology, we aim to develop more effective strategies for monitoring treatment response in rectal cancer patients."

"The analysis of the cytology specimens using bright field multi-staining immunohistochemistry and AI-powered algorithms builds upon our successful proof-of-concept studies with model cells, advancing the field of digital cytology in liquid biopsy applications," says Dr. Nadia Prisant, Head of the Liquid Biopsy Laboratory. "The ability to prepare high-quality cytology slides at the point of blood collection may provide valuable insights into disease progression and help guide treatment decisions for our patients."

"With Tethis See.d instrument we can retrieve the entire population of nucleated cells, including inflammatory cells, histocytes and CTCs from the bloodstream. This gentle collection method enhances the pathologist's ability to detect CTC clusters and single cells, displayed in a unique cellular micro-environment. Through multiplexing of colorectal carcinoma-specific antibodies and localizing the membranous, cytoplasm and nuclear proteins, we expect to enhance CTC detection even in very early-stage patients and evaluate the immunoprofile of the inflammatory background cells to guide immunotherapy," adds Prof. Ruth Katz, Professor of Pathology.

The See.d^® instrument and SmartBioSurface^® slides are for Research Use Only and are not intended for use in diagnostic procedures.
