BACKGROUND The prognostic value and clinicopathologic significance of Ki-67 expression in gastric cancer patients was controversial. This meta-analysis was performed to clarify the prognostic value and clinicopathologic significance of Ki-67 expression in gastric cancer patients. MATERIALS AND METHODS Several electronic databases were searched for eligible studies. The pooled odds ratio (OR),...

OBJECTIVE To determine the accuracy of histopathologic diagnosis in distinguishing eosinophilic esophagitis (EE) from gastroesophageal reflux disease (GERD) in children with upper aerodigestive symptoms. DESIGN Masked review of esophageal biopsy findings and comparison with each child's established clinical diagnosis. SETTING A tertiary care multidisciplinary aerodigestive center. PATIENT...

Purpose: To determine expression levels of CD44 and ALDH1/2, known cancer stem cell (CSC) markers, in stomach adenocarcinomas and assess relationships with clinicopathologic parameters and prognosis. Methods: Eighty patients diagnosed with gastric cancer between the years 2011-2015 were included in this study of clinicopathologic characteristics, postoperative prognostic indexes and stem cell m...

BACKGROUND This study analyzes the clinicopathologic and radiologic characteristics of malignant serous cystic neoplasm (SCN) of the pancreas through systematic review and an institutional case report. METHODS A comprehensive literature search was performed in the MEDLINE database to identify studies on malignant SCNs of the pancreas that had detailed clinicopathologic and radiologic informat...

PURPOSE Small cell carcinoma of the urinary bladder is a highly aggressive malignancy with an average life expectancy of only a few months. Epidermal growth factor receptor (EGFR) has been implicated in the pathogenesis and progression of many malignancies. This study was done to investigate EGFR protein expression and gene amplification in a large series of small cell carcinomas of the urinary...

OBJECTIVE To identify epigenetic events in intestinal-type sinonasal adenocarcinoma (ITAC) and sinonasal squamous cell carcinoma (SNSCC) and to evaluate their relation to clinicopathologic features and follow-up data. STUDY DESIGN Retrospective study. SETTING Academic research hospital. SUBJECTS AND METHODS The methylation status of 23 genes in 50 ITACs and 32 SNSCCs was analyzed by methy...

Microsatellite instability (MSI) is an important factor in the development of various cancers as an identifier of a defective DNA mismatch repair system. The objective of our study was to define the association between microsatellite instability status and traditional clinicopathologic characteristics of endometrioid type adenocarcinoma. MATERIAL AND METHODS MSI status of endometrial cancer w...

Concurrent anti-glomerular basement membrane (GBM) nephritis and membranous nephropathy (MN) is rare previously addressed only in case reports or small series (≤12 patients)1-3. The target antigen(s) MN associated with anti-GBM are unknown. We report the clinicopathologic characteristics outcome of 28 patients this dual glomerulopathy, which were among 449 (6.2%) 5183 (0.5%) non-lupus cases dia...
