The impact of perioperative high-protein oral nutrition supplements on postoperative outcomes in primary lung cancer: the protocol of Russian prospective, randomised, multicenter study

Abstract

BACKGROUND: Nutritional support, including oral nutrition supplements, is an integral part of anticancer treatment, including during surgical treatment of non-small cell lung cancer. Existing evidence for the effectiveness of nutritional support in this cohort of patients is limited. We suggest that the perioperative administration of a balanced polymeric hypercaloric high-protein enteral nutritional formula by sipping as an additional nutrition can have a positive effect on the results of surgical treatment. AIMS: 1) to assess the impact of perioperative nutritional support with high-protein oral nutrition supplements on the risk of postoperative complications, postoperative recovery of respiratory functions, nutritional status and quality of life in patients with primary lung cancer; 2) identification of possible side effects and complications when using high-protein high-energy oral nutrition supplements in patients with non-small cell lung cancer. MATERIALS AND METHODS: Russian prospective, randomised, multicenter low-intervention study of perioperative effect of high-protein nutritional support on postoperative outcomes in the treatment of primary lung cancer with parallel groups, 1:1 randomization. The study will include 114 patients with primary non-small cell lung cancer who are scheduled for surgery. It is expected to provide nutritional support in the perioperative period for 14 days before surgery and for 14 days after it. CONCLUSION: The present study may become one of the first evidence-based studies confirming the effectiveness of perioperative nutritional support with high-protein mixtures in patients with non-small cell lung cancer and will allow further study of the strategy of nutritional support in this category of patients.
