Abstract:

Objective

To investigate the correlation between circulating insulin-like growth factor-1 (IGF-1) and clinicopathological factors in colorectal cancer.

Methods

A total of 113 patients with colorectal cancer diagnosed at our hospital from January 2016 to January 2017 were selected as an observation group. Another 100 healthy volunteers who underwent health examination at our hospital were selected as a control group. Demographic and clinical data for all subjects were collected, and serum IGF-1 levels were measured to explore the relationship between serum IGF-1 and clinicopathological factors in colorectal cancer.

Results

Compared with the control group, the proportion of subjects with histories of drinking, smoking, hypertension, and coronary heart disease, white blood cell count, blood glucose, and serum IGF-1 level were significantly higher and triglyceride level was significantly lower in the observation group (P<0.05). Multivariate analysis showed that smoking, hypertension, coronary heart disease, white blood cell count > the normal range, blood glucose > the normal range, and high serum IGF-1 were risk factors for colorectal cancer (P<0.05). High serum IGF-1 was significantly associated with larger tumor diameter, higher TNM stage, lower degree of differentiation, and lymph node metastasis in patients with colorectal cancer (P<0.05).

Conclusions

Circulating IGF-1 is high in patients with colorectal cancer, and it is associated with clinical stage, tumor differentiation, and lymph node metastasis and can be used as a biological index to predict the occurrence and development of colorectal cancer.
