Specific Nutritional Supplement (Supportan<sup>®</sup>) in the Supportive Care of the Radio-Chemotherapy Treatment of Head and Neck Cancers: Biochemical Parameters. Preliminary Study

This is a preliminary study of a specific nutritional supplement -Supportan(®) - for the clinical support of patients with locally advanced head and neck (H&N) cancers who underwent treatment with concurrent radiochemotherapy (RT-CHT).Seven patients received nutritional supplement (Supportan(®)) plus habitual diet during a median time of treatment with RT on 7.8 weeks plus concurrent weekly CHT(S). Specific serum protein fractions as a potential useful tool to evaluate the nutritional status were determined. The main objective was to assess the compliance with the above-mentioned treatment.Patients completed the nutritional support, 5 / 7 patients via oral route and 2/7 patients through nasogastric tube. All studied patients, that completed treatment, had not severe mucositis -ulcera, hemrraghe and/ or infection. None of them had another severe toxicity by treatment nor had impairment of Pefomance Status. No differences in all specific sera proteins were observed between S and To.In this preliminary study of few patients, we have observed a potential usefulness of Supportan(®) in the compliance of concurrent RT-CHT in patients with H&N cancers; moreover, its administration was useful to maintain the initial biochemical nutritional profile.
