  • Publication number: 20240069028
    Abstract: Provided are biomarkers for predicting the prognosis of cervical cancer. In the case of using the biomarkers of the present disclosure, it is possible to select patients into a high-risk group, an intermediate-risk group, or a low-risk group, and thus, it is possible to provide tailored treatment for each patient according to prognosis prediction.

  • Publication number: 20220291094
    Abstract: Disclosed herein are compositions for fixing tissue for cytologic, histomorphologic, and/or molecular analysis (e.g., DNA, RNA, and/or protein analysis). In some embodiments, the fixatives are aldehyde-free fixatives, for example, formaldehyde- or formalin-free fixatives. Particular disclosed compositions include buffered ethanol. The buffer is a phosphate buffer or phosphate buffered saline (PBS) in some examples. In further embodiments, the fixative includes additional components, such as glycerol and/or acetic acid.

  • Patent number: 11237169
    Abstract: Compositions, methods and kits are described for identifying biomolecules (e.g., proteins and nucleic acids) expressed in a biological sample that are associated with the presence, development, or progression of a disease (such as cancer), or more generally determination of the etiology or risk factors associated with a disease. Sample types analyzed by the disclosed methods include but are not limited to archival tissue blocks that have been preserved in a fixative, tissue biopsy samples, tissue microarrays, and so forth. The methods disclosed herein correlate expression profiles of biomolecules with various disease types, and allow for the determination of relative survival rates; in some embodiments, the methods permit determination of survival rates for a subject with cancer. In other embodiments, the disclosure relates to methods for evaluating therapeutic regimes for the treatment, such as treatment of cancer.

  • Patent number: 9714409
    Abstract: The invention may be broadly defined as the addition of Argon to FFPE procedures as an RNA stabilizing agent. Argon is an inert gas from the Noble gas group with low saturation concentrations in water. It is therefore highly surprising that Argon would have any effect on RNA stability in the presence of Formalin, or any other chemical. This property of Argon appears to be specific in that other inert gases fail to show any RNA stabilizing effect.

  • Publication number: 20170168059
    Abstract: A method for selecting treatment options for patients is provided. The method comprises a procedure for selecting patients that should not be placed on Active Surveillance (AS) but receive active treatment even though the morphologic analysis of the patient's biopsy may show a Gleason score that would traditionally have placed the patient in AS without any further treatment. In accordance with one embodiment, the patient is selected for active treatment if a biomarker associated with prostate cancer is detected. In yet a further embodiment, the patient is selected for additional treatment if the biomarker's concentration is determined to be higher in the benign section of the tissue sample than in the cancerous section. In another embodiment, biochemical recurrence is predicted identifying patients for treatment.
