In multivariate analysis, malnutrition(PG-SGA SF\u2009&gt;\u20095) was significantly associated with worse OS (HR: 1.47,95%CI:1.29\u20131.68), affects the quality of life, and was related to more frequent nutrition impact symptoms. During a median follow-up of 4.5\u2009years, 1176 death occurred. The mortality risk was 41.10% for malnutrition during the first 12\u2009months and led to a rate of 323.98 events per-1000-patient-years. All nutritional assessment tools were correlated with each other (PG-SGA SF vs. PG-SGA: r\u2009=\u20090.98; PG-SGA SF vs. GLIM[Global Leadership Initiative on Malnutrition]: r\u2009=\u20090.48, all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05).
