BACKGROUND In the past two decades, the incidence of breast cancer in young Taiwanese females has been rapidly increasing, approaching the risk level of western countries. As a first step to investigate the possible etiology, we examined the molecular subtypes of female breast cancer in Taiwan. METHODS This study included 1,028 consecutive patients with(More)
Traditional serrated adenoma is one type of colorectal serrated neoplasm and a precursor of colorectal cancer. We evaluated the pathologic and molecular features of 60 traditional serrated adenomas with cytologic dysplasia and/or invasive carcinoma. On the basis of morphological features, 16 cases (27%) were categorized as traditional serrated adenoma with(More)
Telomerase activation and alternative lengthening of telomeres are two major mechanisms of telomere length maintenance. Soft tissue sarcomas appear to use the alternative lengthening of telomeres more frequently. Loss of α-thalassemia/mental retardation syndrome X-linked (ATRX) or death domain-associated protein 6 (DAXX) expression has been implicated in(More)
Annexin A10 (ANXA10) is a member of the ANX family that is normally expressed in gastric mucosa. ANXA10 was recently observed to be upregulated in sessile serrated adenoma, a precursor to microsatellite-unstable colorectal cancer. We investigated the use of ANXA10 in diagnosing colorectal carcinoma. In an immunohistochemical analysis, the intensity and(More)
OBJECTIVE We studied tau and excision repair cross-complementing 1 expression to evaluate their predictive values in advanced breast carcinoma patients. METHODS Patients treated with paclitaxel and cisplatin as the first-line chemotherapy for locally advanced or metastatic breast cancer were enrolled. The expression levels of tau and excision repair(More)
AIMS Moesin belongs to the ERM (ezrin, radixin and moesin) family. Recent in-vitro studies have shown the possible involvement of moesin in epithelial-mesenchymal transition (EMT), but correlating in-vivo evidence is lacking. METHODS AND RESULTS To study the biological significance of moesin, we used immunohistochemistry to investigate the in-situ(More)
Intraductal papillary neoplasms of the bile duct (IPN-Bs) share clinicopathologic features with intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. Approximately two thirds of IPMNs have activating point mutations of GNAS at codon 201. The role of GNAS mutation is unclear in IPN-B. In this study, we evaluated 41 patients diagnosed with IPN-B(More)
Leiomyosarcoma is an aggressive soft tissue sarcoma with poor patient survival. Recently, it was shown that 53% to 62% of leiomyosarcomas use the alternative lengthening of telomeres (ALT) as their telomere maintenance mechanism. The molecular basis of this mechanism has not been elucidated. Studies of pancreatic neuroendocrine tumor have suggested that the(More)
According to cytogenetic aberrations, sarcomas can be categorized as complex or simple karyotype tumors. Alternative lengthening of telomeres is a telomere-maintenance mechanism common in sarcomas. Recently, this mechanism was found to be associated with loss of either α-thalassemia/mental retardation syndrome X-linked (ATRX) or death domain-associated(More)
Hemangioblastoma of the kidney is a rare, newly recognized tumor with morphological features similar to its cerebellar counterpart. There have been only 4 cases reported in the literature in English, all of them occurring in middle-aged to elderly patients. Here, we report a case of renal hemangioblastoma in a young adult without clinical evidence of von(More)
