[Improvement of the nutritional status and quality of life of cancer patients through a protocol of evaluation and nutritional intervention].

Objective: to apply a protocol that facilitates the detection of malnutrition in cancer patients during their treatment of radiotherapy or chemotherapy, selecting those that could benefit from a specific nutritional intervention.

Methodology: malnutrition was assessed with the Malnutrition Screening Tool (MST). Patients at malnutrition risk were evaluated with patient generated subjective-global assessment (PG-SGA) and a subgroup of the sample studied was also assessed with a quality of life (CV) using the EORTC QLQ-C30 questionnaire.
