This lecture will address topics about Home Parenteral Nutrition (HPN) in palliative oncological patients, often hypo- aphagic or in whom oral nutrition is contraindicated because mechanical intestinal obstruction. In fact, in patients with cancer, parenteral nutrition is controversial, although many studies have shown it is able to slow the loss of weight, restore the heritage protein, enhance and prolong survival. According to the main guidelines and evidences, in incurable malnourished cancer patients, palliative home parenteral nutrition should be start if the probability to die from starvation is superior to that of dying from tumor spread, if expected survival is longer than two/three months, if Karnofsky Performance score is more than 50 (patients capable of self-care), if the intake of nutrients by mouth drops to about 60% for a period equal to or more than 10 days and if enteral nutrition is not feasible. The aim is not the rehabilitation, but to guarantee the functionality of vital organs and to improve the quality of life, by reducing physical, psychological and spiritual distress, even thanks to a performance status recovery. The decision to utilize parenteral nutrition in patients with advanced cancer is difficult not only because it assumes the existence of clinical requirements, but also the availability of its management by the patient and family. Data about a study conducted in my clinical nutrition unit on HPN duration in oncological patients will be presented and some consideration on indications of starting or stopping, if already started, an oncological HPN will be done.
