Proliferation Index and Karyometric Features of Pancreatic Intraductal Proliferative Lesions
The increasing frequency and poor prognosis in pancreatic cancer prompt us to search for morphological lesions being a substrate for its development. Studies of autopsy and surgically resected material as well as recent molecular studies have proved that one of the possible pathways of pancreatic neoplasia is the intraepithelial proliferation--dysplasia--cancer sequence. In the present paper we...
متن کاملApplication of Neural Networks to the Classification of Pancreatic Intraductal Proliferative Lesions
The aim of the study was to test applycability of neural networks to classification of pancreatic intraductal proliferative lesions basing on nuclear features, especially chromatin texture. Material for the study was obtained from patients operated on for pancreatic cancer, chronic pancreatitis and other tumours requiring pancreatic resection. Intraductal lesions were classified as low and high...
متن کاملIntraductal Proliferative Lesions of the Breast—Terminology and Biology Matter: Premalignant Lesions or Preinvasive Cancer?
Morphological criteria for the diagnosis of intraductal proliferative lesions of the breast have been an object of research and much controversy, and its terminology is rather confusing. Knowledge of the molecular aspects of this disease probably necessitates further research to clarify if these entities can be identified as breast cancer precursors or as a malignant preinvasive disease. These ...
متن کاملExpression pattern and methylation of estrogen receptor α in breast intraductal proliferative lesions
Intraductal proliferative lesions of the breast including usual ductal hyperplasia (UDH), atypical ductal hyperplasia (ADH) and ductal carcinoma in situ (DCIS) are associated with increased risk, albeit of greatly different magnitudes, for the subsequent development of invasive carcinoma. Estrogen receptor α (ERα) has been widely accepted as a prognostic marker and a predictor for endocrine the...
متن کاملApoptotic Index and Proliferative Index in Premalignant and Malignant Squamous Cell Lesions of the Oral Cavity
BACKGROUND Oral squamous cell lesions are most commonly diagnosed lesions in India. Both premalignant and malignant lesions are frequently encountered. In this study, we evaluated the role and significance of apoptotic indices (AI) and proliferative indices (PI) in premalignant and malignant squamous cell lesions of the oral cavity. MATERIALS AND METHODS A total of 62 histologically proven ca...
