Conclusion This study describes the development of a comprehensible and easy-to-use online patient decision aid for operable oropharyngeal cancer. Outcomes of the interviews state that functional outcome and side-effects are essential for decision making, and experiences of post-treatment patients would be helpful. Survival is found to be of less importance. The feasibility and satisfaction among newly diagnosed patients as well as doctors will need to be proven in clinical practice.

This anatomical location is exposed to a vast scale of microbes, and therefore, abundant colonization and infection may be present. Risk factors for sinonasal lymphomas are positive family history (for Hodgkin disease) and autoimmune disease, immunosuppressive conditions, infection with T-lymphotrophic virus and smoking (for non-Hodgkin disease). EBV has oncogenic potential and is strongly associated with Burkitt’s lymphoma and nasopharyngeal carcinoma, but is also associated with other lymphomas, such as Hodgkin lymphoma, B-cell lymphoma and extra-nodal NK/T-cell lymphoma, nasal type (ENKL). However, the etiological role of EBV remains unclear. In addition to these viruses, modern molecular biology techniques have enabled rapid progression in virus research and discovery. Newly found viruses, such as the protoparvoviruses Cutavirus (CuV),
