Computational pathology systems and methods for early-stage cancer prognosis

ActiveUS20170270666A1Reduce computing costInformed choiceImage enhancementImage analysisComputational pathologyLow risk group
The subject disclosure presents systems and computer-implemented methods for providing reliable risk stratification for early-stage cancer patients by predicting a recurrence risk of the patient and to categorize the patient into a high or low risk group. A series of slides depicting serial sections of cancerous tissue are automatically analyzed by a digital pathology system, a score for the sections is calculated, and a Cox proportional hazards regression model is used to stratify the patient into a low or high risk group. The Cox proportional hazards regression model may be used to determine a whole-slide scoring algorithm based on training data comprising survival data for a plurality of patients and their respective tissue sections. The coefficients may differ based on different types of image analysis operations applied to either whole-tumor regions or specified regions within a slide.

Molecular lymphatic mapping of sentinel lymph nodes

The present invention describes a method for identification and labeling of sentinel lymph nodes (SLNs) and the presence or absence of lymph node metastases as an important diagnostic and prognostic factor in early stage cancers of all types. The method, know as Molecular Lymphatic Mapping, uses traditional dye / radioactive tracer based techniques in conjunction with a nucleic acid marker to identify and label the SLN, not only for current diagnostic methods, but for archival purposes. In addition, MLM can be used to deliver a therapeutic gene or genes to the SLN to activate tumor immunity to tumor cells, and / or to inhibit tumor metastases. The methods may be combined with therapeutic intervention including chemotherapy and radiotherapy.

Method of treatment for early stage cancer

This patent describes a method and materials to treat cancer diagnosed at an early stage, particularly breast cancer. It considers that metastatic breast cancer growth includes periods of dormancy, that surgery to remove a primary tumor can induce metastatic growth, and that women with Down Syndrome rarely get breast cancer. It elevates the level of an antiangiogenic drug produced by chromosome 21 preferably Endostatin in plasma preferably at least one day prior to surgery and kept at that high level preferably indefinitely. The therapy specifically excludes drugs that significantly inhibit the VEGF pathway since that is important for wound healing. This method will prevent results of surgery from stimulating tumor growth and angiogenesis of micrometastatic disease that is much easier to prevent than control after the fact. This can be done indefinitely since there is no acquired resistance that develops, as happens in most cancer therapies.

G-protein coupled receptor-associated sorting protein 1 as a cancer biomarker

A method for determining whether early stage cancer is present in a subject comprises detecting the expression level of GASP-1 in the subject by detecting the amount of GASP-1 peptide fragments present in a biological sample of the subject. Because cancer can be detected at an early stage, therapeutic targeting may be initiated before cancer reaches late stage (e.g., before the development of overt symptoms). A method for treating early stage cancer in a subject comprises administering to the subject an effective amount of a GASP-1 inhibitor to inhibit the progression of early stage cancer to late stage cancer. A Competitive ELISA capable of detecting GASP-1 peptide fragments at a concentration of less than 1 ng / ml was developed.

Phosphoproteins in Extracellular Vehicles as Candidate Markers for Breast Cancer

The state of protein phosphorylation and glycosylation can be key determinants of cellular physiology such as early stage cancer, but the development of phosphoproteins and / or glycoproteins in biofluids for disease diagnosis remains elusive. Here we demonstrate, for the first time, a strategy to isolate and identify phosphoproteins / glycoproteins in extracellular vehicles (EVs) from human plasma as potential markers to differentiate disease from healthy states. We identified close to 10,000 unique phosphopeptides in EVs by isolating from small volume of plasma samples. Using label-free quantitative phosphoproteomics, we identified 144 phosphoproteins in plasma EVs that are significantly higher in patients diagnosed with breast cancer than in healthy controls. Several novel biomarkers were validated in individual patients using Paralleled Reaction Monitoring for targeted quantitation. Similarly a group of glycoproteins in plasma EVs are identified. The study demonstrated that the development of phosphoproteins and / or glycoproteins in plasma EV as disease biomarkers is highly feasible and may transform cancer screening and monitoring.
