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.
