Abstract:
Objective:To investigate the association between metabolic factors,such as obesity,blood pressure,blood glucose,serum lipid profile,and the histopathological characteristics of renal cell carci-noma.Methods:The medical records of 382 consecutive renal cell carcinoma patients who underwent radical or partial nephrectomy at Peking University People’s Hospital from January 2009 to January 2015 were retrospectively reviewed.Metabolic factors were collected from the records,including weight,body mass index,waist circumstance,blood pressure,fasting blood glucose,serum total triglyceride,serum total cholesterol,serum low-density lipoprotein-cholesterol and serum high-density lipoprotein-cholesterol. The patients were divided into different groups according to tumor grade,stage and diameter.Statistics analysis,such as t test,Mann-Whitney U test and Logistic analysis,were performed to investigate the as-sociation between metabolic factors and grade,stage and tumor diameter of renal cell carcinoma.Re-sults:A total of 80 (20.94%)of the tumors were classified as high grade disease,63 (16.49%)were classified as advanced disease and 153 (40.05%)tumor diameter more than 4 cm.The patients in high grade group were found to have lower high-density lipoprotein-cholesterol level than in low grade group (P =0.015),body mass index,total cholesterol and high-density lipoprotein-cholesterol were found to be lower in advanced disease than in localized disease (P =0.022,P =0.005 and P =0.006,respec-tively),and low-density lipoprotein-cholesterol was found to be lower in larger tumors (P =0.030). Other factors were comparable between the different groups.The results of Logistic analyses showed that, body mass index (OR =0.906,95%CI:0.852 -0.986,P =0.023)and total cholesterol (OR =0.660,95%CI:0.492 -0.884,P =0.005)were associated with the tumor stage,high-density lipopro-tein-cholesterol level was significantly associated with tumor grade (OR =0.293,95% CI:0.108 -0.797,P =0.016)and stage (OR =0.204,95%CI:0.065 -0.635,P =0.006),and low-density lipoprotein-cholesterol level was significantly associated with tumor diameter (OR =0.756,95% CI:0.586 -0.975,P =0.031).Conclusion:The results of our study indicate that metabolic factors,espe-cially obesity and serum lipid profile,are closely related with the histopathological characteristics of renal cell carcinoma.
