Background:
This study aims to investigate the effect of lipid metabolism disorder on liver function in patients with malignant tumors after chemotherapy.
Method:
A total of 428 patients with malignant tumors with normal liver function in our hospital between May 2013 to June 2018 were divided into an observation group (lipid metabolism disorder, n = 265) and control group (normal lipid metabolism, n = 163). The lipid metabolism levels and liver damage of the two groups were compared before and after chemotherapy.
Results:
No significant differences in age, gender, body mass index, tumor types, history of surgery, levels of alanine aminotransferase (ALT; an indicator of liver function), and chemotherapy regimen were observed between the two groups. However, the observation group showed increased levels of total cholesterol (P = 0.000), triglycerides (P = 0.000), and low-density lipoprotein (P = 0.01), as well as decreased levels of high-density lipoprotein (P = 0.000) before chemotherapy compared with the control group. Furthermore, patients with lipid metabolism disorders were more likely to develop abnormal liver function after chemotherapy. Moreover, mixed lipid metabolism disorder was more likely to cause severe liver damage after chemotherapy. Additionally, the number of patients with lipid metabolism disorders after chemotherapy (n = 367) was significantly increased compared with before chemotherapy (n = 265) (P < 0.01), indicating that chemotherapy might induce or aggravate an abnormal lipid metabolism.
Conclusions:
After receiving chemotherapy, patients with malignant tumors presenting lipid metabolism disorders are more prone to liver damage and lipid metabolism disorders than patients with a normal lipid metabolism.

Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...
