The impact of diabetes, hypercholesterolemia, and low-density lipoprotein (LDL) on the survival of cervical cancer patients

Abstract

Background Cervical cancer is a prevalent malignancy and an important health concern worldwide. Recent research has highlighted the potential impact of metabolic factors, such as hyperlipidemia and diabetes, on cancer progression, increased mortality, and patient outcomes. However, insufficient data have been reported regarding their relationship with cervical cancer. This study aimed to investigate the relationships between metabolic disorders, including dyslipidemia, dysglycemia, and metabolic syndrome, and survival in patients with cervical cancer. Methods We retrospectively analyzed demographic information, clinical characteristics, and metabolic health indicators of patients with cervical cancer. Patients were categorized into groups based on specific metabolic conditions: high triglyceride, high low-density lipoprotein, high cholesterol, and diabetes groups. Additionally, the presence of metabolic syndrome and other metabolic comorbidities was recorded. The log-rank test was used to compare survival rates between different patient groups and identify associated risk factors. Survival curves generated via the Cox proportional hazards model were used to evaluate the associations between metabolic parameters and survival. Results The Cox proportional hazards model was used to analyze data from 840 patients with cervical cancer between 28 and 72 years old who underwent surgery. The hazard ratio (HR) of mortality was 1.804 (95% CI 1.394–2.333, p < 0.001) in the high-density lipoprotein group, 0.758 (95% CI 0.558 to 1.030, p < 0.001) in the high-triglyceride group, 1.794 (95% CI 1.304–2.470, p < 0.001) in the high low-density lipoprotein group, and 0.011 (95% CI 0.005–0.025, p < 0.001) in the diabetes group. These factors were significantly associated with reduced survival in patients with cervical cancer, and these associations persisted after adjusting for age, cancer stage, treatment type, and the presence of metabolic syndrome or other comorbidities. Conclusion This study highlights the importance of metabolic health and the significance of controlling metabolic disorders, including hyperlipidemia, diabetes, and metabolic syndrome, to improve survival outcomes in patients with cervical cancer. Future research should explore the impact of managing multiple metabolic conditions on the prognosis of these patients.
