RESUMEN

Malignant peritoneal mesotheliomas (MPM) are rare, accounting for approximately 8% of cases of mesothelioma in France. We performed comparative genomic hybridization (CGH) on frozen MPM samples using the Agilent Human Genome CGH 180 K array. Samples were taken from a total of 33 French patients, comprising 20 men and 13 women with a mean (range) age of 58.4 (17-76) years. Asbestos exposure was reported in 8 patients (24.2%). Median (range) overall survival (OS) was 39 (0-119) months. CGH analysis demonstrated the presence of chromosomal instability in patients with MPM, with a genomic pattern that was similar to that described for pleural mesothelioma, including the loss of chromosomal regions 3p21, 9p21, and 22q12. In addition, novel genomic copy number alterations were identified, including the 15q26.2 region and the 8p11.22 region. Median OS was associated with a low peritoneal cancer index (P=.011), epithelioid subtype (P=.038), and a low number of genomic aberrations (P=.015), all of which constitute good prognostic factors for MPM. Our results provide new insights into the genetic and genomic background of MPM. Although pleural and peritoneal mesotheliomas have different risk factors, different therapeutics, and different prognosis; these data provide support to combine pleural and peritoneal mesothelioma in same clinical assays.

RESUMEN

It presents a commentary about alternatives ways to develop diagnostic tools for the infection diseases, neglected diseases, especially malaria, but the long list of diseases with no field-adapted diagnostic tools includes leishmaniasis, shigella, typhoid and bacterial meningitis. It approaches the needs and the Doctors without Borders’s action. Document in PDF format, required Acrobat Reader.
