Article
Molecular assignment of tissue of origin in cancer of unknown primary may not predict response to therapy or outcome: A systematic literature review
(2009)Background: Gene expression profiling platforms were recently shown to accurately assign cancer of unknown primary (CUP) to a primary tissue of origin, with unknown impact on patient outcome. We examined chemotherapy ...

Mutational profiling of the RAS, PI3K, MET and b-catenin pathways in cancer of unknown primary: a retrospective study of the Hellenic Cooperative Oncology Group
(2014)Cancer of unknown primary origin (CUP) had a poor prognosis, determined by clinico-histological characteristics, partly due to the lack of insights on its biology. We screened tumour DNA from 87 patients with CUP for CTNNB1 ...

Novel microRNA-based assay demonstrates 92% agreement with diagnosis based on clinicopathologic and management data in a cohort of patients with carcinoma of unknown primary
(2013)Background: Cancer of unknown or uncertain primary is a major diagnostic and clinical challenge, since identifying the tissue-of-origin of metastases is crucial for selecting optimal treatment. MicroRNAs are a family of ...

Article
Optimal therapeutic management of patients with distinct clinicopathological cancer of unknown primary subsets
(2012)Cancer of unknown primary sites (CUP) is a compilation of various malignant entities-the majority of which behave aggressively and carry poor prognosis. CUP is classified into two different clinicopathological groups: the ...

Original article: Subsets of tumors responsive to cisplatin or carboplatin combinations in patients with carcinoma of unknown primary site: A hellenic cooperative oncology group study
(1992)Summary: In this retrospective analysis 48 patients with metastatic undifferentiated carcinoma, adenocarcinoma and epidermoid carcimona of unknown origin were studied. The purpose of this analysis was to evaluate both the ...

Article
Overexpression of C-myc, ras and C-erb B-2 oncoproteins in carcinoma of unknown primary origin
(1995)The role of oncogenes in carcinoma of unknown primary site (CUP) has not yet been elucidated. In the present study the expression of the c-myc p62, ras p21 and c-erb B p185 oncoproteins were studied by a 3-step immunoperoxidase ...

Article
Perspectives for targeted therapies in cancer of unknown primary site
(2006)Cancer of unknown primary site (CUP) ranks as the fourth most common cause of cancer deaths. Regression of the primary, early development of systemic metastases and resistance to therapy are hallmarks of this heterogeneous ...

Article
Prognostic significance of WNT and hedgehog pathway activation markers in cancer of unknown primary
(2015)Background: Cancer of unknown primary (CUP) possesses distinct biology and peculiar natural history, in which the roles of the winged and hedgehog signalling pathways are unclear. Materials and methods: We constructed ...

Article
Prognostication in cancer of unknown primary (CUP): Development of a prognostic algorithm in 311 cases and review of the literature
(2013)Background: CUP represents a heterogeneous population of patients with systemic malignancy and variable outcomes. Identification of clinical, pathologic and laboratory parameters with prognostic utility could contribute ...

Article
Switching benchmarks in cancer of unknown primary: From autopsy to microarray
(2007)Introduction: Cancer of unknown primary (CUP) is associated with unknown biology and dismal prognosis. Information on the primary site of origin is scant and has never been analysed. We systematically reviewed all published ...
