BACKGROUND A few uterine cervical low-grade squamous intraepithelial lesions (LSILs) are known to progress with high-risk human papillomavirus (hrHPV). METHODS One hundred and thirteen patients were classified into four groups according to their cervical cytology, hrHPV infection, and follow up. Cytology samples were examined for aberrant DNA methylation(More)
OBJECTIVE The aim was to develop a more efficient molecular detection system than histological examination (HE) for lymph node (LN) metastasis. METHODS Cytokeratin (CK) 19 mRNA copy numbers of 5 colon carcinoma cell lines (Lovo, DLD1, WiDr, Colo201 and Colo320) were calculated and compared by one-step nucleic acid amplification (OSNA) and conventional(More)
Objective. To estimate the prevalence and genotypes of high-risk human papillomavirus (HPV) focusing HPV 16, 18, 52, and 58 in Japan. Methods. Liquid-base cytology specimens were collected from Japanese women (n = 11022), aged 14-98. After classifying cytodiagnosis, specimens were analyzed for HPV DNA by the multiplex polymerase chain reaction method, where(More)
Conventional Papanicolaou smear method is still commonly used for cervical cancer screening in Japan, despite the liquid-based cytology (LBC) that has become a global tendency in the world recently. One of the obstacles in the way of popularization of this method seems to be the confusion as to diagnosis upon cervical glandular lesions. We performed(More)
Diagnosis. A VS800 (OLYMPUS, Tokyo, Japan) in a WSI system and an AS-400 (KURABO, Tokyo, Japan) for the ASP systemwere used. Up to 100 slides consisting of biopsy, endoscopic mucosal resection (EMR), or endoscopic submucosal dissection (ESD) specimenswere scanned and stored digitally in one set and the digital images were viewed on a monitor in a separate(More)
Currently, the therapeutic strategy for a breast cancer patient is designed according to their histopathological, immunohistochemical and molecular findings. These findings are obtained through the collected efforts of many individual pathologists or medical technologists (MTs) and are, thus, limited by intra-observer error and potentially subjective(More)
1543 Background: In recent years, molecular biology has firmly established a causal relationship between persistent infection with high-risk human papillomavirus (HPV) genotypes and cervical cancer. While HPV 16 is the most prevalent type in the world, it has been reported that the frequency of other high-risk HPV types varies by region. We estimate the(More)
