Soporte nutricional durante el tratamiento con radiaciones ionizantes en pacientes con tumores de cabeza y cuello en estadios avanzados

malnutrition in the patient with advanced cancer favors immunosuppresion and implies a low karnofsky index, poor tolerance and response to the oncospecific curative or palliative treatments, high susceptibility to infections and, as a result, a decline of the quality of life. patients with head and neck tumors in advanced stages (iii-iv) are one of the groups of high risk for malnutrition due to the reduction of the intake of nutrients, anorexia, alterations of the deglution mechanism, and mechanical obstruction of the upper digestive tract, among other causes.numerous studies show the convenience of the nutritional supplement in these patients during the oncospecific treatment. a prospective study that included 15 patients with head and neck neoplasias in advanced stages, and with clinical signs of malnutrition, was conducted in order to evaluate the necessary calorie-energy supplement. all of them were administered an oral nutritional supplement (adn-22 %) during the radiation treatment to assess the possibility of improving their tolerance and response to the treatment. of the 15 studied cases, 13 presented complications in connection with the treatment, but most them were mild, and they did not affect in a significant way the time of duration and the total dose of treatment. there was a favorable response in relation to the tumor.
