Abstract:
Objective To analyze the clinical features and prognostic factors of patients with malignant tumor complicated by acute kidney injury (AKI),and provide the basis for preventing AKI and improving the prognosis.Methods Malignant tumor patients complicated by AKI were screened with the electronic medical records system from January 2001 to December 2012 at the Affiliated Hospital of Qingdao University.The clinical characteristics in the 12 years were analyzed by statistical analysis and compared.The risk factors of the hospital mortality in malignancies tumor complicated by AKI were analyzed by Logistic regression analysis.Results A total of 100 patients with malignant tumor complicated by AKI were collected,accounting for 24.94％ of AKI patients and 1.66‰ of malignant tumor patients at the same period.Malignancies were consist of hematologic malignancies (11％),non-metastatic solid tumor (47％),metastatic solid tumor (42％).The most common factor leading to AKI for malignancies was post-renal obstruction (64％),followed by nephrotoxic drugs or contrast agents (24％),hypovolemia (18％).There was no significant change of the etiologies for AKI between the first six-year and the second six-year (P ＞ 0.05).The hospital mortality of patients with malignant tumor complicated by AKI was 25％,and multivariate Logistic regression analysis showed that multiple etiologies (OR=13.356),multiple organ failure (OR=222.256),and metastatic solid tumors (OR=8.497) were the independent risk factors for hospital mortality.Conclusions AKI is a common complication in patients with malignant tumors,and the most common factor leading to AKI is postrenal obstruction.The hospital mortality in malignancies with AKI is high,which should get the attention of clinicians.
