OBJECTIVE Since well-differentiated adenocarcinoma cells of the lung (G1 cancer cells) show mild atypia, their differentiation from benign columnar epithelial cells (benign cells) is often difficult based on morphology. We performed discriminant analysis to distinguish benign from malignant cells by measuring 3-dimensional (3D) changes in nuclear luminance.(More)
OBJECTIVES The aims of this study were to determine whether the altered L-type amino acid transporter 1 (LAT1) expression is related to clinicopathologic factors, expressions of Ki-67, p53, estrogen receptor, and progesterone receptor and clarify the significance of LAT1 as a prognostic factor and the novel possibility of using it to treat endometrial(More)
OBJECTIVE To increase the accuracy of the diagnosis of atypical squamous cells of undetermined significance (ASC-US), ASC-US were divided into high-risk human papillomavirus (HPV HR+) and non-high-risk HPV (HPV HR-) cases to analyze the significance of binucleated cells with compression. STUDY DESIGN ThinPrep specimens of ASC-US were examined. This study(More)
OBJECTIVE The cytological diagnosis of coelomic fluid is essential for examining malignant mesothelioma (MM). However, reactive mesothelium (RM), caused by various factors, is morphologically similar to MM and thus often complicates the differential diagnosis. Here, nuclear luminance and steric alterations were assessed for the discriminant analysis of MM(More)
OBJECTIVE Morphological discrimination between malignant mesothelioma (MM) and reactive mesothelium (RM) is often difficult. Stereological analysis of nuclear luminance using centrifuged smear samples from coelomic fluid and discriminant analysis based on Mahalanobis distance may help to more accurately discriminate between MM and RM. In the present study,(More)
OBJECTIVE The Bethesda System (TBS) of uterine cervical cytology is a classification method that can improve accuracy in management and it includes descriptions on adequate specimens, human papillomavirus (HPV) involvement and estimated lesions. However, the judgment of atypical squamous cells of undetermined significance (ASC-US) using TBS features(More)
