Concomitant radio-chemotherapy has become a standard therapy for advanced squamous cell carcinomas of head and neck. Local side effects caused by chemotherapy, like mucositis, increase in combination with radiotherapy. Mucositis, as a painful inflammation and ulceration of the oral mucosa, limits patient´s treatment plan. Studies showed that one third of the patients discontinued Chemotherapy because of the side effects. Accordingly to these side effects, patients eating habits get limited. This requires an increase of pain medication, mostly an opioid derivate, which causes side effects too, which requires other symptomatic medication. This requires a change of nutrition from hard to pappy food and at further impairing, liquid food is needed. A central vein catheter has to be done for parental nutrition and a gastrostomy for enteral nutrition, which means risk of haemorrhage and increased risk of bacteraemias and sepsis for the patient. This would mean a decrease of general condition and a dose reduction or treatment stop is needed. Accordingly, the results are treatment delay and prolongation of hospital stay.
