Objective To investigate the detection of malnutrition in patients with advanced cancer indicators for accuracy . Methods From January to September in 2014 ,100 patients with advanced Ⅲ‐Ⅳ stage cancer were treated in Hangzhou cancer hos‐pital .The clinical data of these patients were retrospectively reviewed ,the data including albumin ,hemoglobin ,total protein ,fasting blood‐glucose ,lactate dehydrogenase ,cholesterol ,triglycerides ,blood urea nitrogen and creatinine and other indicators .Patients′nu‐tritional status was evaluated by PG‐SGA scale and according to the result was graded into PG‐SGA grade A(n=70) ,B(n=8) and C(n=22) .Patients were divided into good nutrition ,moderate malnutrition(potential potentially malnutrition) ,severe malnutrition groups .Take PG‐SGA score as a standard ,evaluation of the above‐mentioned nutritional status of patients with hematology detec‐tion index evaluation accuracy .Results There were significant differences in patients with advanced malignant tumor in hemoglobin and serum albumin among PG‐SGA grade A ,B and C(P<0 .05) .Hemoglobin showed difference between patients of PG‐SGA grade A and C(P=0 .000) ,grade B and C(P=0 .025) .Albumin showed difference in patients between grade A and B(P=0 .003) ,grade A and C(P=0 .000) .Conclusion Hemoglobin ,and serum albumin can be used for evaluating nutritional status in patients with ad‐vanced cancer .
