Intracellular signalling via the AKT axis and downstream effectors is active and prognostically significant in cancer of unknown primary (CUP): a stu…
2012
Background: Hypothesising that cancer of unknown primary (CUP) may harbour unique characteristics, we present a translational study of the immunohistochemical expression and clinical correlation of key PTEN/AKT pathway molecules. Patients and methods: We collected 100 paraffin-embedded CUP tissue blocks. We studied using tissue microarrays the expression of PTEN, phospho-AKT, Cyclin D1, p21, phospho-RPS6. From the percentage of staining tumour cells and the literature, we selected cut-offs to classify the expression of each biomolecule. We correlated IHC expression with clinical data. Results: PTEN, pAKT, and pRPS6 showed frequent expression. At univariate analysis, high IHC expression of p…
Pathology of Breast and Ovarian Cancers among BRCA1 and BRCA2 Mutation Carriers: Results from the Consortium of Investigators of Modifiers of BRCA1/2…
2012
Abstract Background: Previously, small studies have found that BRCA1 and BRCA2 breast tumors differ in their pathology. Analysis of larger datasets of mutation carriers should allow further tumor characterization. Methods: We used data from 4,325 BRCA1 and 2,568 BRCA2 mutation carriers to analyze the pathology of invasive breast, ovarian, and contralateral breast cancers. Results: There was strong evidence that the proportion of estrogen receptor (ER)-negative breast tumors decreased with age at diagnosis among BRCA1 (P-trend = 1.2 × 10−5), but increased with age at diagnosis among BRCA2, carriers (P-trend = 6.8 × 10−6). The proportion of triple-negative tumors decreased with age at diagnos…
Sorafenib: from literature to clinical practice
2013
Sorafenib is considered the standard systemic therapy for hepatocellular carcinoma (HCC), in patients with well-preserved liver function (Child-Pugh A class) and advanced-stage HCC (BCLC-C) or in patients with HCC progressing after locoregional therapies, with a high grade of recommendation. The approval of sorafenib for this indication was grounded on the efficacy and the safety results reported by two international randomized, controlled trials, the SHARP and the Asia-Pacific studies. In addition, the efficacy and the safety of sorafenib in clinical practice are addressed by several field-practice experiences, including the multinational GIDEON study and the SOFIA study. Finally, further …
Ovarian cancer susceptibility alleles and risk of ovarian cancer in BRCA1 and BRCA2 mutation carriers
2012
Germline mutations in BRCA1 and BRCA2 are associated with increased risks of breast and ovarian cancer. A genome-wide association study (GWAS) identified six alleles associated with risk of ovarian cancer for women in the general population. We evaluated four of these loci as potential modifiers of ovarian cancer risk for BRCA1 and BRCA2 mutation carriers. Four single-nucleotide polymorphisms (SNPs), rs10088218 (at 8q24), rs2665390 (at 3q25), rs717852 (at 2q31), and rs9303542 (at 17q21), were genotyped in 12,599 BRCA1 and 7,132 BRCA2 carriers, including 2,678 ovarian cancer cases. Associations were evaluated within a retrospective cohort approach. All four loci were associated with ovarian …
CD133 as a target for colon cancer.
2012
INTRODUCTION: Recent evidence based on cancer stem cell (CSC) models, is boosting the progress of translational research and providing relevant clinical implications in many tumour types, including colorectal cancer. The current failure of standard therapies is attributed to a small fraction of the primary cell population with stem-like characteristics, such as self-renewal and differentiation. Identification of CSCs is based on two different criteria of selection: stemness-selective conditions and direct isolation based on putative stem cell markers expression. CD133, a transmembrane glycoprotein, was associated with tumor-initiating cells derived from several histological variants of tumo…
Precision Medicine in Oncology: Glossary of Relevant Scientific Terms
2021
The conventional oncological approach was defined in the past as “one size fits all” and the tumors were treated according to the localization and the histopathological features. One of the future challenges in the field of oncology is the integration of translational research and technology innovation, in order to clarify unexplored aspects of the biology and the genetics of tumors, to develop a personalized treatment based on the molecular characteristics of the patient and his disease, that is the principle of precision medicine. New multidisciplinary teams are needed to ensure the integration of different professional profiles, including oncologists, pharmacologists, geneticians, and pa…

Functional categories of TP53 mutation in colorectal cancer: results of an International Collaborative Study.
2006
Item does not contain fulltext BACKGROUND: Loss of TP53 function through gene mutation is a critical event in the development and progression of many tumour types including colorectal cancer (CRC). In vitro studies have found considerable heterogeneity amongst different TP53 mutants in terms of their transactivating abilities. The aim of this work was to evaluate whether TP53 mutations classified as functionally inactive (< or=20% of wildtype transactivation ability) had different prognostic and predictive values in CRC compared with mutations that retained significant activity. MATERIALS AND METHODS: TP53 mutations within a large, international database of CRC (n = 3583) were classified ac…
Interlingual translation of the International Financial Reporting Standards as institutional work
2017
The International Financial Reporting Standards (IFRS) have been widely adopted well beyond English-speaking jurisdictions. Using the Finnish translation of the IFRS as a primary object of investigation, this article analyses the way in which the standards are translated into another language. Drawing on interviews with translators and translation review committee members and on an analysis of archival materials, it provides an empirically grounded understanding of practical problems of linguistic equivalence, and the institutional work required to maintain the IFRS as a global, translingual institution. Accordingly, the article highlights the constructed and negotiated nature of the lingui…
