 note = {Background: Nutritional status and tumor markers are important prognostic indicators for surgical decisions in pancreatic carcinoma. This study aimed to stratify the probability of surviving pancreatic carcinoma based on systematically chosen nonanatomic biomarkers. Methods: We included 187 consecutive patients that underwent surgical resections for pancreatic carcinoma. We performed multivariable analyses to evaluate prognostic indicators, including 4 blood-test indexes: the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, prognostic nutritional index, and the modified Glasgow prognostic score; and 4 body-composition indexes: the normalized total psoas muscle area, the normalized total elector spine muscle area, the psoas muscle computed tomography value, and the elector spine muscle computed tomography value. Results: Poor survival was associated with 2 independent risk factors: neutrophil-to-lymphocyte ratio ≥3.0 (hazard ratio, 1.54) and prognostic nutritional index <36 (hazard ratio, 1.60), and with high carbohydrate antigen 19-9 levels (≥37 IU/mL). The 2 indexes were not significantly associated with clinicopathological factors, including carbohydrate antigen 19-9. Patients with no risk factors had significantly better survival than those with 1 (P = .007) or 2 risk factors (P = .001), and survival was similar in the latter 2 groups (P = .253). A presurgical nonanatomic scoring system (range, 0−2) was constructed: 0 points for no risk factors, 1 point for 1 or 2 nutritional risk factors, and 1 point for carbohydrate antigen 19-9 ≥37 IU/mL. Survival rate at 3 years decreased with increasing scores (76% for score 0, 42% for score 1, and 21% for score 2; all P < .05). Conclusion: Neutrophil-to-lymphocyte ratio and prognostic nutritional index were independent prognostic risk factors in pancreatic carcinoma and integrating these indexes with carbohydrate antigen 19-9 levels could successfully stratify survival.},
