RESUMO
Objective To investigate the clinical significance of monitoring the serum levels of Thyroglobulin (Tg) and Thyroglobulin Autoantibody (TgAb) in the 131I ablation therapy for patients with differentiated thyroidcarcinoma (DTC).Methods 102 patients with DTC treated by 131I ablation therapy in our hospital from May 2014 to July 2016 were selected.The serum levels of Tg and TgAb were detected by radioimmunoassay before 131I ablation therapy,6 months after I 13 1I ablation therapy and 12 months after 131I ablation therapy.The body imaging were performed at seventh days after 1311 ablation therapy.Results The serum levels of Tg and TgAb at 6 months and 12 months after surgery were significantly lower than those before operation,and the difference were statistically significant (t =9.260,17.507,2.534,4.797,P ＜ 0.05).The serum levels of Tg and TgAb in metastasis group were higher than that in non-metastasis group (t =10.257,7.353,P ＜0.05).The serum levels of Tg and TgAb in the effective group were lower than those in the ineffective group,and the difference were statistically significant (t =7.325,4.978,P ＜ 0.05).The positive rate of Tg combined with TgAb was similar with 131I-WBS screening methods and the difference was not statistically significant (P ＞ 0.05).The positive rate of Tg screening method and the positive rate of TgAb were higher than that of 131I-WBS screening method,but the difference was not statistically significant (P ＞ 0.05).Conclusions The level of serum Tg and TgAb is an important reference index for the efficacy,metastasis and recurrence of DTC after operation,and Tg combined with TgAb has a higher accuracy in the screening prognosis of DTC after operation.
RESUMO
Objective To analyze the clinical effects of internal radiation of iodine-125 seed implantation in the treatment of advanced pancreatic carcinoma.Methods 22 patients with unresectable and advanced pancreatic carcinoma were treated by the internal and interstitial radiation using iodine-125 seed implantation.Results Survival of 20 months was observed in 5 patients,10 ～ 20 months in 9 patients,2 ～10 months in 8,patients with an average of (13.47 ± 8.12) months.Among the 22 patients,complete response was obtained in 5 patients,partial response in 8 patients,no response in 7 paticnts,and the other showing PD.The response rate( CR + PR) was 59％.Conclusions Intra - operative internal radiation by iodine - 125 seed implantation does show some therapeutic effects for advanced pancreatic carcinoma.
