The predict value of serum CA125 in epithelial ovarian cancer,fallopian tube cancer and peritoneal cancer chemotherapy reactivity / 重庆医学

ABSTRACT

Objective To investigate the changes of CA125 level with intra-abdominal tumor(epithelial ovarian cancer ,fallopian tube cancer and peritoneal cancer ) before and after chemotherapy serum and their effect on the prognosis of patients and their the clinical predictive value .Methods 174 cases(107 cases of epithelial ovarian cancer ,35 cases of fallopian tube cancer ,and 32 cases of peritoneal cancer) with peritoneal cancer patients were selected from January 2007 to January 2008 .The percentage decrease of ser-um CA125 were calculated after 3 courses of chemotherapy and CA125 decreased level of sensitivity with chemotherapy were ana-lyzed .The different levels of CA125 of median survival time and median survival time were compared .Results After chemothera-py ,CA125 decreased ≥ 75% in 42 cases ,decreased from 51% to 75% in 62 cases ,decreased from 25% to 50% in 32 cases ,and de-creased less than 25% in 38 cases .In CA125 decreased ≥ 75% group ,the chemotherapy effects was better than the other groups (P<0 .05) .Univariate analysis showed that the decrease proportion of CA 125 was positively correlated with chemotherapy effect (r=0 .396 ,P=0 .000) .Using the Kaplan-Meier method ,the patient's survival rate and median survival time were caculated and it showed that the 5 years survival and median survival time were significantly better in group CA 125 decline ≥ 75% than the other groups(P<0 .05) .Univariate analysis shows that the CA125 decline proportion of patients and long term efficacy was positively correlated(r=0 .412 ,P=0 .000) .The COX risk model analysis showed that FIGO stage ,CA125 level and the effect of chemothera-py were independent prognostic risk factors .Conclusion The level of CA125 is the independent risk factor of epithelial ovarian cancer ,fallopian tube cancer and peritoneal cancer prognosis .CA125 decline proportion could be used to know the effect of chemo-therapy and long term treatment ,and be the prognosis indicators for patients with intra abdominal tumor .
