Investigation of a Polyphenol-rich Preparation as Support for Oncology Patients Undergoing Gastrointestinal Tumor Resection

Oncology patients undergoing the procedure are exposed to various postoperative complications. Nutridrink with a mixture of extracts with anti-inflammatory and antioxidative properties aims to provide the patient with essential nutrients and bioactive substances that can reduce the inflammatory state, protect cells from oxidative damage, and decrease the risk of complications while supporting tissue healing processes after the surgical procedure. The study group are oncology patients undergoing surgical resection of gastrointestinal tumour. During the study, the effects of the mixture on levels of oxidative stress and inflammation markers will be assessed, as well as the subjective evaluation of patients' quality of life and well-being after surgical surgical tumor resection.
