摘要： Systems and methods relating to a cell-based pattern recognition tool for microscopy images from tissue sections are described, wherein cell features are extracted and a classifier is built in accordance with a particular application using an interactive training tied to a computerized platform, the result is an application-specific classifier that further processes images in accordance with the specific application, thereby tuning an automated process for cell based pattern recognition.

摘要： The present invention provides diagnostic methods for predicting the effectiveness of treatment of a cancer patient with an EGFR kinase inhibitor. These methods are based on the surprising discovery that the effectiveness of treatment with an EGFR kinase inhibitor is predicted by whether a patient's tumor cells express a high or a low level of the biomarkers vimentin and E-cadherin, such that patients whose tumors express a high level of at least one of the biomarkers vimentin and E-cadherin have a longer overall survival and progression free survival than patients whose tumors express a low level of both vimentin and E-cadherin. The present invention further provides a method for treating tumors or tumor metastases in a patient, comprising the steps of diagnosing a patient's likely responsiveness to an EGFR kinase inhibitor by assessing whether tumor cells express a high level of at least one of the biomarkers vimentin and E-cadherin, and administering to said patient a therapeutically effective amount of an EGFR kinase inhibitor (e.g. erlotinib), particularly when effectiveness of the inhibitor is predicted.
