A method for diagnosing or differentially diagnosing a cancer characterized by the presence of cancer cells in the pleural fluid of a mammalian subject, the method comprising contacting a sample of pleural fluid of the subject with colloidal magnetic particles coupled to a ligand which binds to a determinant on a cancer cell, but does not bind above a baseline threshold to other cellular and non-cellular components in pleural fluid; subjecting the pleural fluid-magnetic particle mixture to a magnetic field to produce a cell fraction enriched in ligand coupled-magnetic particle-bound cancer cells, if present in the pleural fluid; and analyzing the enriched fraction for the number of cancer cells in the pleural fluid. In certain aspects, this method involves preparing the pleural fluids for the above-noted method steps by, e.g., dilution of unprocessed pleural fluid. In certain aspect, the pleural fluid is subjected to the diagnostic method within 24 hours of withdrawal from the subject. This method has advantages to present diagnostic procedures for identifying malignant pleural effusions. The tumor cells present in pleural fluid can be characterized with cellular and molecular markers to determine prognostic and predictive factors.

Compositions, systems, and methods comprising circulating endothelial cells (CECs) are provided. The compositions described herein utilize isolated CECs, including compositions in a form that allows analysis of the CECs. The systems described herein utilize isolated CECs and an analytical tool or an output from an analytical tool. The methods described herein are related to the use of isolated CECs and analytical tools for providing information, to a health care provider or the CEC donor, that is relevant to the cardiovascular health of the CEC donor. Thus, the compositions, systems and methods described herein involve both a transformation (e.g., non-isolated CECs to isolated CECs, or isolated CECs to analyzed CECs) and a machine (e.g., isolation tools and analytical tools).

Methods for the detection, enumeration and analysis of circulating tumor cells expressing insulin-like growth factor-1 receptors (IGF-1R) are disclosed. These methods are useful for cancer screening and staging, development of treatment regimens, and for monitoring for treatment responses, cancer recurrence or the like. Test kits that facilitate the detection, enumeration and analysis of such circulating tumor cells are also provided.

The present invention provides a method of identifying origin of a metastasis of unknown origin by obtaining a sample containing metastatic cells; measuring Biomarkers associated with at least two different carcinomas; combining the data from the Biomarkers into an algorithm where the algorithm normalizes the Biomarkers against a reference; and imposes a cut-off which optimizes sensitivity and specificity of each Biomarker, weights the prevalence of the carcinomas and selects a tissue of origin determining origin based on highest probability determined by the algorithm or determining that the carcinoma is not derived from a particular set of carcinomas; and optionally measuring Biomarkers specific for one or more additional different carcinoma, and repeating the steps for additional Biomarkers.

Methods are disclosed for the identification of gene sets that are differentially expressed in PBMCs of patients diagnosed with a pre-diabetic disease state and overt type II diabetes. 3 gene and 10 gene signatures are shown to accurately predict a diabetic disease state in a patient. The application also described kits for the rapid diagnosis of diabetic disease states in patients at a point of care facility.

The disclosed method rapidly identifies with desired accuracy AML patients, including elderly AML patients, likely to respond to treatment with a combination of a farnesyltransferase inhibitor and one or more of etoposide, teniposide, tamoxifen, sorafenib, paclitaxel, temozolomide, topotecan, trastuzumab and cisplatinum. In an embodiment, the improvements include the use of whole blood rather than the customary bone marrow sample, thus making the assay more accurate, rapid, less intrusive, less expensive as well as less painful. The method includes evaluation of a two-gene expression ratio (RASGRP1:APTX), which with a corresponding threshold, provides sufficient accuracy for predicting the response to the combination treatment. In the preferred embodiment the combination treatment combines tipifarnib (R115777, ZARNESTRA) with etoposide. Further, the elderly AML patients identified as being likely responsive to the combination treatment with tipinifarb and etoposide have a complete recovery rate comparable to the best therapy available for younger patients.

Methods are disclosed for the identification of gene sets that are differentially expressed in PBMCs of patients diagnosed with a pre-diabetic disease state and overt type II diabetes, 3 gene and 10 gene signatures are shown to accurately predict a diabetic disease state in a patient. The application also described kits for the rapid diagnosis of diabetic disease states in patients at a 5 point of care facility.
