Value of skeletal muscle index combined with interleukin-6 and activin A in predicting early-stage pancreatic cancer cachexia
Objective To investigate the value of L3 skeletal muscle index(L3-SMI)combined with interleukin-6(IL-6)and activin A in predicting early-stage pancreatic cancer cachexia.Methods A total of 74 patients with pancreatic cancer who were diagnosed in Hebei Medical University Forth Hospital from July 2020 to July 2023 were enrolled,and according to the presence or absence of cachexia after admission,the patient were divided into cachexia group with 58 patients and non-cachexia group with 16 patients.The levels of L3-SMI,IL-6,and activin A were observed within 48 hours after admission.The independent-samples t test was used for comparison of normally distributed continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.A multivariate Logistic regression analysis was used to investigate the influencing factors for pancreatic cancer cachexia;the receiver operating characteristic(ROC)curve was used to analyze the value of L3-SMI,IL-6,and activin A alone or in combination in predicting pancreatic cancer cachexia,and the Z test was used for comparison of the area under the ROC curve(AUC).Results Compared with the non-cachexia group,the cachexia group had a significantly higher level of L3-SMI and significantly lower serum levels of IL-6 and activin A(t=8.649,3.049,and 8.100,all P＜0.05).The multivariate logistic analysis showed that L3-SMI(odds ratio[OR]=0.266,95%confidence interval[CI]:0.103-0.683,P＜0.05),serum IL-6(OR=4.158,95%CI:1.368-12.333,P＜0.05),and activin A(OR=5.124,95%CI:1.550-16.939,P＜0.05)were influencing factors for pancreatic cancer cachexia.L3-SMI,IL-6,and activin A alone had a significantly lower AUC than the combination of the three indicators in predicting pancreatic cancer cachexia(0.851/0.752/0.791 vs 0.946,Z=-2.841,-2.552,and-2.647,all P＜0.001),and the combination of the three indicators had the highest sensitivity(90.9%),specificity(87.8%)and Youden index(0.788).Conclusion L3-SMI combined with serum IL-6 and activin A has a good value in predicting early-stage pancreatic cancer cachexia.
