Abstract

During the Montebello Conference on malignant serosal tumours at Lillehammer, Norway, in June 2004, a group of 30 international experts addressed the biologic and genetic aspects of malignant tumours affecting serosal cavities in the human body. Three neoplasms were mainly dealt with: mesotheliomas arising locally, ovarian carcinomas developing in close proximity to the serosa, and breast tumours in which the spread came from some distance. New, important data on the tumour microenvironment and the process of carcinogenesis with progression and acquisition of invasive properties shed new lights on the mechanisms, including proliferative properties, alterations of signal transduction pathways, and tissue remodelling by proteolytic enzymes in the metastasizing cells. Several of these markers have considerable diagnostic and clinical interest. In addition, new aspects of morphologic and immunocytochemical characteristics of the cells as well as genetic markers may soon become powerful tools for practical use. The molecular fingerprint of the individual tumours may also give guidelines for chemotherapy as well as biologic therapies, including induction of apoptosis. The easy accessibility of tumours from serosal fluids and possibilities for specific discrimination of the neoplastic cells from admixed leukocytes and other cells are promising avenues for cytodiagnostics.
