  • Patent number: 11585816
    Abstract: An automated method and system for determining the risk of developing a cancer in a subject, the method comprising preparing a tissue sample obtained from the subject for visually identifying at least one biological marker associated with the cancer, digitally scanning the prepared tissue sample, analyzing the scanned image of the tissue sample to identify regions of interest, quantifying at least one parameter associated with the marker, and executing an algorithm using the quantified parameter to calculate a risk score, wherein the risk score is representative of the risk of the individual developing the cancer.

  • Patent number: 6730514
    Abstract: The present invention is directed to a stable, continuous, human oral squamous cell carcinoma cell line from the floor of the mouth of a habitual tobacco consumer using a variety of growth supplements and complement mediated lysis to obtain a fibroblast free culture. This cell line has the ability to produce tumor in athymic nude mice. The cell line of the present invention constitutes a system that is suitable for detecting and screening for new and effective anti-cancer therapies. This cell line provides in vitro and in vivo (xenographts in athymic mice) oral tumor model which is useful for understanding molecular basis of oral cancer development, identifying targets for designing novel therapeutic strategies, testing new gene therapy approaches for oral cancer and testing novel synthetic retinoids for chemoprevention of oral cancer.
