Role of ErbB family receptor tyrosine kinases in intrahepatic cholangiocarcinoma

World Journal of Gastroenterology 2008年第46期14卷 7033-7058页

作者： Alphonse E Sirica division of Cellular and molecular Pathogenesis Department of PathologyVirginia Commonwealth University School of Medicine

Aberrant expression and signaling of epidermal growth factor receptor (ErbB) family receptor tyrosine kinases, most notably that of ErbB2 and ErbB1, have been implicated in the molecular pathogenesis of intrahepatic cholangiocarcinoma. Constitutive overexpression of ErbB2 and/or ErbB1 in malignant cholangiocytes has raised interest in the possibility that agents which selectively target these receptors could potentially be effective in cholangiocarcinoma therapy. However, current experience with such ErbB-directed therapies have at best produced only modest responses in patients with biliary tract cancers. This review provides a comprehensive and critical analysis of both preclinical and clinical studies aimed at assessing the role of altered ErbB2 and/or ErbB1 expression, genetic modifications, and dysregulated signaling on cholangiocarcinoma development and progression. Specific limitations in experimental approaches that have been used to assess human cholangiocarcinoma specimens for ErbB2 and/or ErbB1 overexpression and gene amplification are discussed. In addition, current rodent models of intrahepatic cholangiocarcinogenesis associated with constitutive ErbB2 overexpression are reviewed. Select interactive relationships between ErbB2 or ErbB1 with other relevant molecular signaling pathways associated with intrahepatic cholangiocarcinoma development and progression are also detailed, including those linking ErbB receptors to bile acid, cyclooxygenase-2,interleukin-6/gp130, transmembrane mucins, hepatocyte growth factor/Met, and vascular endothelial growth factor signaling. Lastly, various factors that can limit therapeutic efficacy of ErbB-targeted agents against cholangiocarcinoma are considered.

Background:A central challenge in cancer research is to create models that bridge the gap between the molecular level on which interventions can be designed and the cellular and tissue levels on which the disease phenotypes are *** study was undertaken to construct such a model from functional annotations and explore its use when integrated with large-scale cancer genomics ***:We created a map that connects genes to cancer hallmarks via signaling *** projected gene mutation and focal copy number data from various cancer types onto this *** performed statistical analyses to uncover mutually exclusive and co-occurring oncogenic aberrations within this ***:Our analysis showed that although the genetic fingerprint of tumor types could be very different,there were less variations at the level of hallmarks,consistent with the idea that different genetic alterations have similar functional ***,we showed how the multilevel map could help to clarify the role of infrequently mutated genes,and we demonstrated that mutually exclusive gene mutations were more prevalent in pathways,whereas many co-occurring gene mutations were associated with hallmark ***:Overlaying this map with gene mutation and focal copy number data from various cancer types makes it possible to investigate the similarities and differences between tumor samples systematically at the levels of not only genes but also pathways and hallmarks.

Multilevel oblique corpectomies as an effective surgical option to treat cervical chordoma in a young girl

引用

World Journal of Clinical Cases 2014年第3期2卷 57-61页

作者： Roberto Delfini Daniele Marruzzo Roberto Tarantino Nicola Marotta Alessandro Landi Department of Neurology and psychiatry Division of Neurosurgery University of Rome "Sapienza"

Chordomas are malignant tumors arising from notochordal remnants. They are the most frequent tumors of the spine after plasmacytomas. Only 6% of chordomas are localized to the cervical level. In young patients, chordomas are rare and unpredictable. Despite this, the treatment of choice remains the total resection, as much as possible, followed by proton beam radiation. This case was managed using a precarotid and retrocarotid approach at the same time. The tumor was completely resected with the edges free from disease. The cervical spine was stabilized with an anterior plating C2-C4. Eighteen months after surgery the patient is still free from illness. Multilevel oblique corpectomies are an available and safe option for the treatment of upper cervical chordomas.
