Non-surgical oncology - Guidelines on Parenteral Nutrition, Chapter 19

Area of Science:

• Oncology
• Clinical Nutrition
• Metabolism

Background:

• Reduced nutritional status negatively impacts cancer patient outcomes and quality of life.
• Active cancer often leads to inadequate food intake and altered metabolic pathways.
• Tumors can trigger systemic inflammation affecting metabolic processes.

Purpose of the Study:

• To stabilize nutritional status in cancer patients to prevent weight loss.
• To maintain or improve patients' quality of life.
• To enhance the effectiveness and reduce side effects of antitumor therapies.

Main Methods:

• Nutritional support via oral, enteral, or parenteral nutrition (PN).
• Preference for oral/enteral nutrition when feasible, with combined approaches if needed.
• PN indications similar to benign conditions, with specific considerations for cancer patients.

Main Results:

• PN is indicated for severe radiogenic enteritis or post-transplant gastrointestinal damage.
• PN is not generally recommended as an adjunct to standard radiotherapy or chemotherapy.
• No PN is advised during the terminal phase of illness.

Conclusions:

• Nutritional support is crucial for managing cancer patients' well-being and treatment outcomes.
• Parenteral nutrition is a valuable tool when other methods are insufficient or not feasible.
• Careful consideration of PN indications and risks is essential in oncology care.
