Abstract:
OBJECTIVE To investigate the prognostic value of serum creatinine-cystatin C ratio(CCR)for nasopharyngeal carcinoma(NPC).METHODS NPC patients who underwent consultation at the Army 72nd Group Military Hospital from January 2007 to December 2015 were retrospectively analyzed and divided into high-expression and low-expression groups according to whether the CCR was＜0.81(median),and the predictive variables of the high-expression and low-expression groups were compared.Kaplan-Meier survival analysis and Cox regression were used to analyze the effect of CCR on overall survival(OS),and clinical prediction models and column line diagrams were constructed and evaluated based on relevant predictive factors.RESULTS A total of 516 NPC patients were included.The percentage of elderly patients in the high-expression group(22.5%)was significantly lower than that in the low-expression group(32.6%),and the percentage of highly-differentiated patients(22.5%)was significantly higher(14.7%),and the percentage of patients with TNM stage Ⅰ and Ⅱ(40.7%)was significantly higher than that in the low-expression group(29.8%),and the differences of the above indexes were all statistically significant(P Kaplan-Meier survival analysis suggested that low-expression CCR was significantly associated with poorer OS,and multifactorial Cox regression analysis showed that age,CCR,pathologic grade,time from diagnosis to treatment,and TNM stage were significantly associated with OS(P＜0.05).The clinical prediction model constructed on the basis of the above predictive factors had higher AUC values than the traditional TNM staging model,and its column line graph predicted OS with good agreement with the actual.CONCLUSION CCR can be considered as a potentially useful prognostic factor for NPC patients.
