Oral cavity cancers are the seventh tumor by diffusion worldwide with more than 90 % being diagnosed as oral squamous cell carcinomas (OSCCs). According to the latest WHO statistics, OSCC accounts for 5 % of the cancer deaths worldwide, being the eighth more lethal cancer entity. Early identification of cancer relapses would have the potentiality to improve the disease control and the patient survival. NeoMark is a European co-funded research project (Seventh Framework Program, Information and Communication Technologies: EU-FP7-ICT-2007- 2-22483-NeoMark) that has the objective to identify relevant biomarkers of OSCC recurrence. It integrates high-throughput gene expression analysis in tumor cells and IT-assisted imaging with traditional staging and follow-up protocols to improve the recurrence risk stratification and to obtain the earlier identification of locoregional relapses. The architecture of the project is based on the following key points: – Creation of a web application tool: a unified interface that helps the storage and management of all information – NeoMark database: the heterogeneous NeoMark data (demographics and risk factors; clinical, pathological, and immunohistochemical parameters; filtered and cleaned genomic and imaging data) are stored in a single database – the Integrated Health Record Repository (IHRR) – on a central NeoMark server. The server contains the marker definition functional environment (MDFE), a data analysis module. Based on the heterogeneous input data, it estimates the likelihood of a relapse and identifies OSCC risk factors. – Imaging biomarker extraction: several biomarkers are obtained from medical images such as CT and MRI scans (size, amount of necrosis from tumor and lymph nodes, etc.). To extract those features, a custom software tool – called the NeoMark Image Processing Tool – has specifically been developed. – Genomic data cleaning and filtering: extraction of genomic data and filtering of genes with low data quality and of those with high number of missing values. The NeoMark system was trained and initially validated in a multicenter pilot study (three European clinical centers involved: two in Italy and one in Spain) basing on 86 patients affected by OSCC with a minimum follow-up of 12 months. The clinicians recognized the usefulness of the disease bioprofile (or diseasespecific profile) identified by NeoMark to evaluate the risk of disease reoccurrence of a patient at diagnosis, to stratify patients affected by OSCC at baseline according to the risk of recurrence, and to reserve a “tailored therapy” to each case.
