Abstract

Abstract:

Objective To investigate the role of atypical cells（ATYP. C）in urine analysis and blood-related inflammatory indicators in the auxiliary diagnosis of bladder cancer and MTHFR gene typing. Methods Totally，207 patients with bladder cancer（bladder cancer group）and 56 non-tumor subjects（control group）were enrolled from Shanghai Cancer Center of Fudan University. The clinical data were collected，and blood routine test，urea，creatinine（Cr），uric acid（UA），MTHFR genotype and ATYP. C were performed and determined. The neutrophil-to-lymphocyte ratio（NLR），monocyte-to-lymphocyte ratio（MLR），platelet-to-lymphocyte ratio（PLR）were calculated. Logistic regression analysis（forward：LR）was used to evaluate the influencing factors of bladder cancer occurrence. Receiver operating characteristic（ROC）curve was used to evaluate the efficacy of ATYP. C in diagnosing bladder cancer. Results The proportion of urinary tract infection，urea，NLR，MLR，PLR and ATYP. C in bladder cancer group were higher than those in control group（P<0.05），while UA，white blood cell（WBC）count，the absolute value of mid-sized cells（MID#），the absolute value of basophils（BASO#） and the absolute value of lymphocytes（LYMPH#） were lower than those in control group（P<0.05）. There was no statistical significance in Cr，platelet（PLT）count，the absolute value of neutrophils（NEUT#）and the absolute value of eosinophils（EO#）（P>0.05）. ATYP. C and PLR abnormalities were independent risk factors for bladder cancer occurrence（P<0.01）. The areas under curves（AUC）of ATYP. C，PLR，NLR and MLR for diagnosing bladder cancer were 0.898，0.734，0.753 and 0.647，respectively. Regardless of the presence or absence of urinary tract infection，ATYP. C was an independent risk factor for bladder cancer occurrence（P<0.05）. The abnormal rate of ATYP. C in patients with TT genotype（93.62%）was higher than those in patients with CC genotype（76.19%） and CT genotype（83.33%）（P=0.016）. Conclusions ATYP. C is related to the occurrence of bladder cancer and the MTHFR gene C677T polymorphism，and it may be one of the indicators for the auxiliary diagnosis of bladder cancer.
