Based on the abstracts received and accepted for oral presentation, general sessions 1-13 will be devoted to either specific subtypes of lymphoid neoplasia (e.g. mantle cell lymphomas, follicular lymphomas, T-cell lymphomas, etc), or to the presentation of laboratory and clinical research data grouped around a biologic topic (for example, microenvironment, signalling pathway, surface antigens). The latter sessions will be introduced by an expert summarising the topic.
