1 The impact of nutrition intervention in cancer patients Paula Ravasco Unidade de Nutrição e Metabolismo Instituto de Medicina Molecular Faculdade de Medicina da Universidade de Lisboa deterioration is multifactorial clinical evidence on complex interactions between cancer and/or treatment-related variables & factors, all exerting a combined effect on patients wasting: protein/energy intake deficits were determinant for deterioration; cancer location was the dominant factor influencing the wasting pattern and/or progression; tumour burden for the host was the most significantly associated with worse status.
