Mini-nutrition assessment, malnutrition, and postoperative complications in elderly Chinese patients with lung cancer.

Purpose: To assist healthcare professionals in using the mini nutrition assessment (MNA) and its short-form (MNASF) for early identification of malnourished elderly lung cancer patients, conducting preoperative nutritional support, and improving patients' postoperative prognosis, quality of life, and survival.

Methods: The MNA with revised cut-off points to better suit the Chinese population was conducted on 103 elderly lung cancer Chinese patients aged 60 or above in the Tianjin Cancer Hospital prior to their scheduled surgery. Patient demographic data, anthropometric parameters, biochemical markers, and postoperative complications were collected and analysed.
