ABSTRACT

Objective To study the value of SCCAg,CYFRA21-1 and TPS in the diagnosis and prognostic evaluation of patients with cell cervical cancer (SCC).Methods The levels of serum SCCAg,CYFRA21-1and TPS from 160 SCC patients and 60 health women were detected by means of ELISA.Results ( 1 ) The levels of serum SCCAg,CYFRA21-1and TPS in SCC were significantly higher than those of normal group ( P ＜0.001 ).The median values of normal group0.43 μg/L,0.43 μg/L,26 U/L,the median values of cervical cancer group1.96 μg/L,2.29 μg/L,149.1 U/L ( 2 ) The specificity of SCCAg,CYFRA21-1 and TPS in diagnosing SCC were both 100％.The sensitivity of SCCAg,CYFRA21-1 and TPS in diagnosing SCC was 53.42％,40.68％ and 83.95％,respectively.The sensitivity of TPS was obviously different from SCCAg and CYFRA21-1 ( P ＜0.001 ).The sensitivity of SCCAg plus CYFRA21-1 and three markers together were 69.23％and 92.31％,respectively.(3)The expressing of SCCAg,CYFRA21 -1 and TPS in FIGO stages Ⅲ plus Ⅳ was significantly higher than in stages Ⅰ plus Ⅱ (P ＜ 0.05 ),and all markers were not related to the degree of histological differentiation.SCCAg was correlated strongly with tumor size,growth type,lymph node metastasis and age( P ＜ 0.05 ),but CYFRA21-1 was not correlated with all these factors.TPS level was significantly associated with tumor size and lymph node metastasis( P ＜0.05 ),but not with growth type and age.(4)A total of 78 patients were followed up.The pretreatmental serum levels of SCCAg and CYFRA21-1 in patients with recurrence were significantly higher than those without recurrence( P ＜0.05 ).The same trend was not found for TPS.Compared with the normal control,the patients with elevated SCCAg before treatment has shorter intervals before recurrence and metastasis occurred.Also,the survival of patients with elevated SCCAg before treatment was shorter than the normal control ( P ＜ 0.05 ).Conclusion SCCAg,CYFRA21-1 and TPS serum levels are valuable markers for the diagnosis of SCC.Meanwhile,SCCAg and CYFRA21-1 are chnically significant pridictors for the prognosis of SCC.
