title: [Current therapy options in recurrent head and neck cancer].
abstract: Recurrent disease is one of the main reasons for the persistently poor prognosis of squamous cell carcinoma of the head and neck (HNSCC; European 5-year survival, 42%). The main treatment option for primary and secondary malignancy as well as recurrent disease is surgical therapy. If R0 resection (resection margin >5 mm) for a primary tumor is not viable, survival probability is reduced by 50%. In recurrent or secondary tumors with R1- or -2 resection or in the presence of non-resectable metastases, a palliative situation results in more than 80% of cases. In the case of surgery following radiotherapy or radiochemotherapy, attention should be paid to the criteria for salvage surgery (tissue perfusion, fibrosis, wound healing) and the procedure adapted to focus on functionality. In the case of relapse, primary surgery can potentially be supplemented with adjuvant therapy protocols such as (re-) irradiation, as well as possibly with chemotherapeutic agents or targeted therapies. Interdisciplinary collaboration and case discussions should take place in the context of a tumor board.
