Abstract
Background: In the metastatic setting, cancer patients may not benefit from standard care regimes and their diseases undergo drug resistance due to tumour cell heterogeneity and genomic landscape complexity. In recent years, there have been several attempts to personalise the diagnostic-therapeutic path and to propose novel strategies based on not only histological test results but also on each patient's clinical history and molecular biology. Profiling molecular tests allows physicians to investigate the single tumour genomic landscape and to promote targeted approaches. The Molecular Tumour Board (MTB) is a multidisciplinary committee dedicated to selecting individualised and targeted therapeutic strategies appropriate for patients suffering from diseases that present resistance to standard care. Materials and Methods: Our MTB settled in "Azienda Ospedaliero Universitaria delle Marche", Ancona (AN), Italy, and includes oncologists, molecular biologists, geneticists, and other specialists. Clinical cases are referred by physicians to the MTB, through the Cancer and Research Centre of the Marche Region (CORM), through a telemedicine platform. Four possible molecular profiles are available: FoundationOne(®) CDx e FoundationOne(®)Liquid CDx and two local Next Generation Sequencing (NGS) panels, with 16 DNA genes and 10 RNA genes respectively. The resulting genetic mutations and their analyses are evaluated by all the members of the Board and a report for each patient is provided with medical recommendations. Results: from June 2021 to May 2023, we collected data from 97 referral patients (M: 49, F: 48). The mean age was 60.6 years (range 22-83 years). 90 cases were approved for testing. Only seven patients were not eligible for genomic profiling. In two patients who were eligible, molecular profiling was not performed because a tissue sample was not available. Off-label therapy was recommended for three patients. 5% of cases (5/88) showed addressable driver mutations associated with an existing targeted therapy and were immediately enrolled. Conclusions: MTB presents a powerful tool for offering precise medical goals. Our Department of Clinical Oncology also takes advantage of the important role of multidisciplinary teams, through the establishment of CORM and MTB meetings, within which there is the chance to perform NGS-based analyses. It will be important in the future to implement the use of genomic profiling to improve personalised care and to guide the choice of suitable therapies and more appropriate management of patients.
