A survey including the PG\u2010SGA and other questionnaires was completed by 34\u00a0071 adult hospitalized cancer patients with first cancer diagnosis or recurrent disease with any tumour comorbidities from the INSCOC study. Among them, 1558 patients were followed for 5\u00a0years after admission. Reliability and rank correlation were estimated to assess the consistency between PG\u2010SGA items and to select mPG\u2010SGA items. The external and internal validity, test\u2013retest reliability, and predictive validity were tested for the mPG\u2010SGA via comparison with both the PG\u2010SGA and abridged PG\u2010SGA (abPG\u2010SGA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After deleting items that more than 50% of professionals considered difficult to evaluate (Worksheet 4) and items with an item\u2010total correlation &lt;0.1, the mPG\u2010SGA was constructed. Nutritional status was categorized using mPG\u2010SGA scores as well\u2010nourished (0 points) or mildly (1\u20132 points), moderately (3\u20136 points), or severely malnourished (\u22657 points) based on the area under curve (0.962, 0.989, and 0.985) and maximal sensitivity (0.924, 0.918, and 0.945) and specificity (1.000, 1.000, and 0.938) of the cut\u2010off scores. The external and internal validity and test\u2013retest reliability were good. Significant median overall survival differences were found among nutritional status groups categorized by the mPG\u2010SGA: 24, 18, 14, and 10\u00a0months for well\u2010nourished, mildly malnourished, moderately malnourished, and severely malnourished, respectively (all\n                      <jats:italic>P<\/jats:italic>\n                      s\u00a0&lt;\u00a00.05).
