Nutritional Care in Patients with Head and Neck Cancer during Chemoradiotherapy (CRT) and Bioradiotherapy (BRT) Provides Better Compliance with the Treatment Plan

SIMPLE SUMMARY: The nutritional status of patients with head and neck cancer (HNC) during concurrent chemoradiotherapy (CRT) with platinum derivatives or concurrent radiotherapy with cetuximab (bioradiotherapy, BRT) inevitably deteriorates during treatment. Malnutrition is responsible for increased treatment-related toxicity, an increased incidence of infectious complications, the risk of postponing or discontinuing therapy, reduced drug doses (platinum derivatives or cetuximab), deteriorating quality of life (QoL), worse outcome, and increased treatment costs. A nutritional care programme, which included prophylactic dietary counselling and early enteral nutrition, reduced the incidence of complications and prevented drug dose reduction and the deterioration of patients’ anthropometric and laboratory parameters. The study confirmed that nutritional care before and during CRT and BRT in patients with HNC is a determinant of therapeutic benefit. ABSTRACT: The treatment of locally advanced head and neck cancer (HNC) is based on extensive resections followed by concurrent chemoradiotherapy (CRT) with platinum derivatives or concurrent radiotherapy with cetuximab (bioradiotherapy; BRT). Malnutrition, which occurs in up to 60% of patients before treatment commencement, severely increases the risk of CRT/BRT drug dose reductions and the incidence of treatment-related adverse events. A prospective observational study was performed regarding the influence of nutritional care on nutritional status, compliance with the treatment’s planned regimen, and the incidence of treatment-related complications in patients with advanced HNC during CRT and BRT. The study population encompassed 153 patients compared with a retrospective control group of 72 patients treated before nutritional care was included in the standard of oncological care. Patients enrolled in the nutritional care programme received significantly higher doses of platinum derivatives or cetuximab than patients in the control group. A significant difference between the compared populations was observed in patients below 70 years of age (92.8% of the study population), after prior surgery, and with initial weight loss lower than 10%. Nutritional care reduced final weight loss and prevented a decline within the laboratory markers of nutritional status. Weight loss was comparable in both modes of treatment—CRT and BRT. The incidence of treatment-related complications was significantly higher in patients without nutritional support in the subgroups of patients under 70 years of age and after primary surgery. Nutritional care before and during CRT and BRT in patients with HNC is a determinant of therapeutic benefit, defined as preventing down-dosing, weight loss, and the incidence of complications. Platinum derivatives and cetuximab had comparable influence on weight loss.
