Middle Ear Carcinoma

Cancer care for head and neck cancers is multidisciplinary and complex and knowledge on the rare ones is limited. There is a wide consensus that to support clinical research on rare cancers, clinical registries should be developed within networks specializing in rare cancers. Our hypothesis is that our head and neck cancer registry established in the framework of the European reference network on rare adults solid cancers will help to: describe the natural history of rare head and neck cancers; evaluate factors that influence prognosis; assess treatment effectiveness; measure indicators of quality of care. The registry is a prospective observational real-world registry. It collects data from already available registries/database and/or directly from expert health care providers (HCP). Information are prospectively collected on patient characteristics; exposure, outcomes and potential confounders (https://euracan.eu/research/starter/rare-head-and-neck-cancer-registry/#codebook). The registry if federated (i.e. data are stored by the data provider). Analyses will be performed using the federated learning approach which split computations into a local part and a central part.
