About this study
Peritoneal mesothelioma is a rare disease representing one third of all mesothelioma and nothing is known about molecular characteristics of this disease. As main cancers, genetic heterogeneity is probable. This genomic profiling associates Comparative Genomic Hybridization (CGH) array, BAP1 sequencing and gene expression in order to discover a biomarker that could be used in the treatment of this rare disease. Corresponding histopathological and immunohistochemical report as all clinical data are available. All data with be merged to underline a few genes of interest on which we will focus our next investigations. Depending of our preliminary results, BAP1 mutations are expected, as it was also described in pleural mesothelioma. Mutations in oncogenic drivers that could be targeted by specific therapy will be on particular interest in management of this rare disease with bad prognosis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
comparative genomic analysisGenetic
DNA and RNA extraction will be performed in Lyon University hospital (genomic platform) using commercially available kit. Percentage of tumors cells will be controlled by stained section before extraction. The CGH arrays will be realized on frozen samples in Lille (genomic platform). Pangenomic Agilent array will be used. Micro-array include 180000 probes. Analysis will be performed in Lille (genomic platform / department of BioInformatics) with Marie Brevet. Data will be processed from the log2 transformed data into normalization with the WACA method. Then copy number variation will then be identified with Circular Binary Segmentation. Copy number variations will be called as gain or deletion according to the log2 ratio distribution and the percent of tumoral cells. Using matched tumoral and normal DNA will eliminate Copy Number Polymorphisms. We will construct non supervised hierarchical analyses to study the classification of peritoneal mesothelioma based on copy number variation

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
BAP1 mutations (time frame: Day 0). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jul 2016.
