Prevalence of kidney disease in patients with different types of cancer or hematological malignancies: a cross-sectional study.

Abstract

This study investigated the prevalence and risk factors of acute kidney injury (AKI) and chronic kidney disease (CKD) in cancer patients with the aim of providing guidance for clinical treatment of cancer patients. A retrospective study was conducted on all cancer and hematological malignancy patients admitted to Xuanwu Hospital, Capital Medical University, from January 2018 to July 2023. The study population included patients aged 18-80years with a confirmed cancer or malignancy diagnosis. Chi-square tests, Spearman's correlation, and logistic regression were used to evaluate the relationships between demographic factors, comorbidities, cancer types, antitumor drugs and the prevalence of AKI/CKD. Among the 2438 participants, the prevalence rates of AKI and CKD were 3.69% and 7.88%, respectively. Patients with diabetes had higher prevalence of AKI/CKD than those without diabetes (OR = 1.66, 95% CI 1.01-2.68, p = 0.040; OR = 1.60, 95% CI 1.10-2.31, p = 0.012, respectively). In addition, a higher prevalence of CKD was observed in patients with hypertension (OR = 3.49, 95% CI 2.43-5.06, p < 0.001). Underweight patients were more likely to develop AKI (OR = 2.66, 95% CI 1.03-6.08, p = 0.029). Anthracyclines may contribute to a higher risk of AKI, and antimetabolites and immunomodulators may be associated with the development of CKD. Overall, patients with hematological malignancies had significantly higher rates of AKI/CKD than those with solid tumors. Among solid tumor patients, the prevalence of AKI/CKD was low in patients with lung and breast cancer. AKI and CKD prevalence varies across cancer types, influenced by factors, such as diabetes, hypertension, body weight, and antitumor drugs. Tailored treatment plans are essential for improving cancer patient outcomes.
