Parenteral nutrition in cancer patients outside of oncologic treatment: Bioethical perspective.

BACKGROUND AND AIMS: The medical care of a patient with an end-stage disease focus on the pursuit of the patient's quality of life. Many treatments can be used to achieve this goal. In this study, the benefits, and burdens of providing parenteral nutrition to patients diagnosed with end-stage cancer were reviewed and analyzed from a bioethical perspective with the aim of issuing a useful recommendation for decision making.

METHODOLOGY: A qualitative convergent study through interviews and a multiple case study was performed. The study is on the decisions to provide parenteral nutrition as an end-of-life treatment for terminal cancer patients treated in Mexico City. Eight physicians specialized in Oncology and Palliative Care were interviewed and 10 clinical records of patients diagnosed with terminal cancer, who were out of oncologic treatment, who received palliative care and were prescribed parenteral nutrition at the end of life were analyzed.

RESULTS: The physicians considered parenteral nutrition as an advanced life-sustaining medical treatment and, therefore, susceptible to not being initiated or being withdrawn, according to the patient's clinical situation. Minor complications secondary to parenteral nutrition were found in all the records reviewed, all these patients died in hospital instead of at home.

CONCLUSION: When death is certain in the short term and cannot be avoided, the role of feeding and nutrition becomes questionable, especially in cancer patients at the end of life, where parenteral nutrition causes more burden than benefit.
