In this paper, we propose to adapt to immunohistochemistry (IHC) some methods proposed to normalize images from histological slices stained with hematoxylin-eosin (H&E). Our final aim is to provide a coherent quantitative characterization of IHC biomarkers across different IHC batches with possible staining variations. In contrast to H&E, IHC staining strongly varies with the tissue analyzed...
Purpose To evaluate the efficiency of the UCA1 test as a diagnostic tool for the detection of bladder cancer. Methods Between October 2009 and December 2011 the UCA1 test was performed on collected urine samples from 162 patients divided into screening and follow-up groups, based on the absence or presence of prior bladder cancer. The test performance was then evaluated in each group and compared...
Whole‐slide scanners allow the digitization of an entire histological slide at very high resolution. This new acquisition technique opens a wide range of possibilities for addressing challenging image analysis problems, including the identification of tissue‐based biomarkers. In this study, we use whole‐slide scanner technology for imaging the proliferating activity patterns in tumor slides based...
Glioblastomas are very aggressive cerebral tumors which are characterized by strong proliferative activity which is often assessed using the Ki-67 staining method. We propose a novel clustering method that exhibits high performance to detect Ki-67 hot-spots on immunohistochemical slides of glioblastomas.
