Objective  To investigate the relationship between the level of serum-insulin like growth factor-1
( IGF-1) and the nut ritional status of cancerous cachexia. Methods  Colon cancer CT-26 cells were implanted subcutaneously to 30 liver2specified IGF-1 gene deleted (L ID) C57BL/ 6 mice to establish cancerous cachexia model and the
other 30 C57BL/ 6 mice were included as cont rol group. The serum levels of IGF-1 , cytokine TNF-αand IL-6 , blood
glucose , albumin and t riglyceride were detected respectively on day 14 , 18 and 22 af ter the plantation of tumor. The
body weight of mice , tumor weight and the weight af ter tumor removed in two group s were measured respectively.
Results  Af ter the plantation , the levels of IGF-1 in L ID group at different times were all significantly lower than
those in cont rol group ( P lt; 0. 05) . The serum levels of TNF-α, IL-6 , blood glucose and t riglyceride were ascending
gradually over time ( P lt; 0. 05) , but weight s af ter tumor removed and the level of albumin were descending in two
group s ( P lt; 0. 05) . Compared with the cont rol group , the serum levels of IL-6 , TNF-α, blood glucose and t riglyceride in L ID tumor-bearing mice were all significantly higher at different time point s ( P  lt; 0. 05) . On day 18 and 22 ,
the weight s af ter tumor removed and the amount of ingestion in L ID group were significantly lower than those in the
cont rol group ( P lt; 0. 05) . Conclusion  Compared with the low level of IGF-1 in cancerous cachexia , normal level of
serum IGF-1 may represent lower degree of cancerous cachexia2related cytokines and better nut ritional state , which
may provide a novel idea of the therapy of cancerous cachexia.
