ABSTRACT

Objective:To investigate the clinical features of patients with recurrent or metastatic differentiated thyroid carcinoma(DTC)after 131I therapy. Methods:From December 2000 to December 2017, a total of 40 patients[14 males amd 26 females, median age 48(29-60)years] with recurrent or metastatic DTC after 131I therapy in Tianjin Medical University General Hospital were reviewed. We analyzed the clinical pathological features of the patients receiving the initial 131I ablation to screen the relevant factors affecting the time of recurrence or metastasis, the dynamic serological changes, imaging characteristics and the iodine uptake in the lesion at diagnosis. Chi- square test, Mann- Whitney U test and Kaplan- Meier analysis were used to compare the differences between the two groups. Results:The time of recurrence or metastasis of DTC after 131I therapy was not statistically different in the patient′s age, gender, multifocal cancer, lymph node metastasis, the interval between the initial 131I therapy and the operation, stimulated thyroglobulin(Tg)levels before the initial ablation and last 131I therapy, and times of 131I therapy( P > 0.05), but associated with the T-stage of in-situ tumor, soft tissue metastasis and initial therapeutic dose of 131I. Patients with the T4-stage of in-situ tumor( P=0.033), soft tissue metastasis( P=0.008)and tumor initial dose≤3.7 GBq( P=0.002)were more prone to early recurrence or metastasis. From termination of 131I therapy to the diagnosis of tumor recurrence or metastasis, Tg [Tg antibodys(TgAb)negative] and TgAb(TgAb positive)showed a gradually increasing trend. Recurrent or metastatic lesions were mostly located in the cervical lymph nodes, and most of them were multiple. Among the 40 patients with recurrent or metastatic DTC, only 3 patients had iodine-avid lesions. Conclusion:The T-stage of in-situ tumor, soft tissue metastasis and initial therapeutic dose of radioiodine are important factors affecting the time of recurrence or metastasis after 131I therapy in DTC patients. Most of the recurrent or metastatic lesions don′t ever concentrate radioiodine, so it′s difficult to benefit from continued 131I therapy.

ABSTRACT

Objective To compare the ablation efficacy and therapy response with 1. 1 GBq and 3. 7 GBq 131I in postoperative patients with low- and intermediate-risk differentiated thyroid carcinoma (DTC). Methods A total of 190 patients (43 males, 147 females, age:(45.8±11.1)years) were enrolled from July 2016 to July 2017. Among them, 96 patients received 1.1 GBq 131I and 94 were given 3.7 GBq 131I. Diagnostic whole-body scan was performed 6 months after 131 I ablation for treatment response evaluation, and the successful rate of 131I ablation was calculated. χ2 test or Fisher's exact test was used for data analysis. The cut-off value of 99 Tcm-pertechnetate uptake for predicting the successful rate of remnant thyroid ablation in 1.1 GBq group was determined by receiver operating characteristic ( ROC) curve analysis. Results The successful ablation rates in 1.1 GBq and 3.7 GBq groups were 79.2%(76/96) and 81.9%(77/94), respec-tively (χ2=0.229, P>0.05). There was no significant difference in the therapy response between the two groups (χ2=1.371, P>0.05) . The successful ablation rate in 3.7 GBq group was higher than that in 1.1 GBq group for patients with stageⅢ(5/6 vs 1/7, P=0.029). Moreover, for patients with 5μg/L<preablative-stimula-ted thyroglobulin (ps-Tg)≤10μg/L, the ablation rate in 1.1 GBq group was lower than that in 3. 7 GBq group ( 3/11 vs 10/13, P=0.038) . ROC curve analysis showed the cut-off value of 99 Tcm-pertechnetate uptake for prediction of the successful ablation rate in 1.1 GBq group was 0. 0615. Conclusion The low- and inter-mediate-risk DTC patients with stageⅢdisease, 5μg/L<ps-Tg≤10μg/L or higher 99 Tcm-pertechnetate up-take of remnant thyroid should be given 3.7 GBq other than 1.1 GBq 131I to obtain a better ablation efficacy.

ABSTRACT

Objective To investigate the influence of different time discontinuation of compound iodine solution on 131Ⅰ uptake and curative effect of 131Ⅰ therapy in patients with Graves disease (GD).Methods A total of 1 585 patients (415 males,1 170 females;age range:17-62 years) treated with 131Ⅰ therapy for the first time between January 2012 and November 2016 were enrolled in this retrospective study.All patients were divided into preliminary treatment group (n =85) and control group (no iodine solution taking,n =1 500).Preliminary treatment group including 4-7 d discontinuation subgroup (group A,n=35),8-14 d discontinuation subgroup (group B,n=28) and 15-30 d discontinuation subgroup (group C,n=22).The high-est radioactive iodine uptake (RAIU),effective half-life,free triiodothyronine (FT3) and free thyroxine (FT4) levels before 131Ⅰ therapy were compared,and curative effects were evaluated.One-way analysis of variance,Ridit analysis and x2 test were used to analyze the data.Results The highest RAIU in group A,group B,group C and control group was (64.86 ± 13.20) %,(67.40 ± 9.10) %,(73.46 ± 4.65) % and (74.14±9.87) %,respectively (F =1.658,P> 0.05).No significant difference was found in the effective half-life among 4 groups (F=0.651,P>0.05).FT3 level in group A and group B ((11.90±4.85) and (15.51±2.95) pmol/L) was significantly lower than that in control group ((23.98±4.98) pmoL/L) and group C ((22.08±2.31) pmol/L;F=13.972,t values:6.57-12.08,all P<0.05).FT4 level in group A and group B ((25.65±11.95) and (32.33±6.25) pmol/L) was obviously lower than that in control group ((73.65±21.55) pmol/L) and group C ((68.41±13.94) pmo]/L;F=21.238,t values:36.09-48.00,all P<0.01).The overall curative effect of preliminary treatment group and that of control group were not statistically significant (u=0.397,P>0.05),and no significant difference was found in the complete remission rates among 4 groups (x2 =1.169,P>0.05).Conclusions If pretreatment with compound iodine solution is used before 131Ⅰ therapy in GD,it is feasible to carry out 131Ⅰ therapy within 2 weeks after withdrawal.In order to avoid the possibility of severe hyperthyroidism after 131Ⅰ therapy,it is recommended that radioiodine treatment should be carried out after discontinuation for 4-7 d.

ABSTRACT

Objective To investigate the radioactivity distribution of 131 I-bovine serum albumin ( BSA )-mesoporous silica nanoparticles ( MSNs )-anti-vascular endothelial growth factor receptor 2 (VEGFR2) in anaplastic thyroid carcinoma (ATC) and to explore its antitumor efficacy in ATC-bearing nude mouse models. Methods 131 I-BSA-MSNs-anti-VEGFR2 and 131 I-BSA-MSNs were constructed. FRO tumor xenografts were established and the SPECT/CT images of tumor-bearing mice were acquired at differ-ent time points after intratumoral injection with 131 I-BSA-MSNs-anti-VEGFR2 ( targeting group) , 131 I-BSA-MSNs ( non-targeting group) , Na131 I ( Na131 I group) and saline ( control group) , respectively. The changes of body mass and tumor volume in each group were recorded. Two-sample t test and log-rank test were used to analyze the data. Results After incubation for 3 h, the fluorescence intensity in targeting group was higher than that in non-targeting group (345.26±16.35 vs 280.61±9.65;t=5.90, P<0.05). After injection for 1-3 weeks, the radioactivity detected by SPECT/CT in targeting group was obviously stronger than that in non-targeting group ( t values:7.060-12.780, all P<0.05) . At the end of the observation, the tumor vol-ume of Na131I group, control group, non-targeting group and targeting group increased to (278.3±19.3)%, (296.6±24.2)%, (198.7±13.2)% and (103.7±6.2)% of the original volume, respectively. The body mass of the first 2 groups decreased to (88.6±3.0)% and (86.2±3.1)% of the original body mass respec-tively, while that of the latter 2 groups increased to (102.1±3.1)% and (116.2±3.4)% of the original body mass respectively. Survival analysis showed that the median survival time in targeting group ( 38 d) was sig-nificantly longer than that in non-targeting group (34 d;χ2=8.05, P<0.05). Conclusion 131I-BSA-MSNs-anti-VEGFR2 can effectively inhibit the tumor growth of ATC and prolong the survival of tumor-bearing nude mice, which gives a good suggestion for the treatment and prognosis evaluation of ATC.

ABSTRACT

Objective To analyze the stimulated thyroglobulin (sTg) level and variation tendency before and after 131I therapy in papillary thyroid carcinoma (PTC),and evaluate the predictive value of sTg for the efficacy of 131I therapy.Methods From January 2013 to September 2016,a total of 178 PTC patients (53 males,125 females;average age (44.1±11.4) years) without distant metastases who received 131I treatment in Tianjin Medical University General Hospital were reviewed.The patients were divided into two groups:group 1 (n=23) with residual thyroid detected by 131I whole body scan (WBS) and group 2 (n=155) without residual thyroid.Both thyroid stimulating hormone (TSH) and sTg were measured and defined as TSH1,sTg1 before 131I therapy,and TSH2,sTg2 after 131I therapy.Data of the two groups were compared with two-sample t test,x2 test and Mann-Whitney u test.The receiver operating characteristic (ROC) curve and diagnostic critical point (DCP) were used to evaluate the predictive value of sTg in radioiodine ablation efficacy.Results There were no significant differences in age (t=1.007),gender (x2 =1.419),tumor diameter (u=1 385),multifocal cancer (x2 =0.371),extrathyroidal extension (x2 =0.020) or lymph node metastasis (x2=0.391,all P>0.05) between group 1 and group 2.The levels of sTg1 and sTg2 of group 1 were 6.3(2.0,16.9) and 1.7(0.8,4.2) μg/L,which were higher than those of group 2 (2.7(0.6,6.4) and 0.3(0.2,1.3) μg/L;u=1 118.5,817.0,both P<0.01).△sTg and △sTg/△TSH showed no statistical differences between the two groups (u =1 359.5,1 195.0,both P>0.05).The area under ROC curve,DCP,sensitivity,specificity,positive predictive value,and negative predictive value of sTg1 were 0.686,4.435 μg/L,60.9%(14/23),67.7%(105/155),21.9% (14/64) and 92.1%(105/144),respectively.Meanwhile,the parameters of sTg2 were 0.771,0.460 μg/L,91.3% (21/23),58.1% (90/ 155),24.4%(21/86) and 97.8%(90/92),respectively.Conclusions The level of sTg could be used to predict the efficacy of 131I therapy in PTC patients.Preablative sTg1 (<4.435 μg/L) or postablative sTg2 (< 0.460 μg/L) holds high negative predictive value in identifying the efficacy of single 131I therapy.

ABSTRACT

Objective To investigate the correlation between external dose equivalent rate (EDER)and residual radioactivity in DTC patients after 131I therapy.Methods A total of 70 DTC patients (15 males,55 females;average age (45.7±12.8) years) who received 131I therapy from January 2015 to May 2015 were reviewed.Patients were divided into remnant ablation group (Group 1,43 patients) and the group of therapy for persistent disease (Group 2,27 patients).The determination of dose equivalent rate at 1,2 and 3 m from the patients was performed at 1,6,18,24,30,42,48,54,66 and 72 h after the administration of 131 I.Simultaneously,the residual radioactivity was estimated through collecting their urine and monitoring the excretion of radioactivity.The correlation between EDER and residual radioactivity was analyzed.Results The functions of standard EDER (μSv · h-1 · MBq-1) at 1 m from the patients of Group 1 and Group 2 were H=0.044 77e-0.063 8t +0.015 04e-0.396t.and H=0.039 71e-0.0629t +0.014 12e-0.325t,respectively.And the functions of residual radioactivity (MBq) of the two groups were A =A0(0.84e-0.061 7t+ 0.16e-0.158 4t)and A =Ao(0.69e-0.087 7t+ 0.31e-0.047 3t),respectively.There was a positive correlation between EDER and residual radioactivity in DTC patients after the administration of 131I (r=0.95,P<0.001).The fitting function of the dose equivalent rate at 1 m from the patients was H(μSv/h)=0.048A (MBq).Conclusions The residual radioactivity in DTC patients after 131 I therapy can be estimated by determining the EDER.The dose equivalent rate at 1 m from the patients of lower than 19.2 μSv/h can be used as the limitation of radiation isolation.

ABSTRACT

Objective Liver dysfunction is a common complication of hyperthyroidism [ mainly Graves’ disease(GD)], that may restrict the choice as well as affect the ultimate outcome of treatment. The purpose of this study was to describe the clinical and biochemical patterns in patients suffering from Graves’ disease and liver dysfunction and to determine influential factors. Methods A total of 1 928 patients received radioactive iodine, 131 I treatment. Before 131 I therapy, 24 h radioactive iodine uptake of thyroid(24 h RAIU), serum free triiodothyronine (FT3 ), free thyroxine( FT4 ), sensitive thyroid-stimulating hormone( sTSH), anti-thyrotrophin receptor antibody (TRAb), thyroglobulin antibody(TgAb), anti-thyroid peroxidase antibody(TPOAb), and serum hepatic function parameters etc were performed. Data were analyzed by the unpaired t-test, the independent samples t-test, the χ2 test, logistic regression, and Pearson bivariate correlation. Results Ages, the course of Graves’ disease, the weight of thyroid, FT4 , TPOAb, and TRAb in Graves’ disease patients complicated with liver dysfunction were higher than those in patients with normal hepatic function, as shown in table 1. The influential factors including age, course of Graves’ disease, heart rate, weight of thyroid, FT4, 24 h RAIU, TgAb, TPOAb, and TRAb. 24 h RAIU were the protecting factors. Age, course of Graves’ disease, heart rate, weight of thyroid, FT4 , TRAb, and TPOAb were the risk factors. Conclusion The risk of liver dysfunction in patients with Graves’ disease was increased in the following cases: age over 45 years, heart rate above 90 bpm, weight of thyroid more than 35 g, course of Graves’ disease longer than 3 years, FT4 greater than 70. 5 pmol/ L, TPOAb above 360 IU/ ml, and TRAb above 15 IU/ L. In these coses 131 I therapy will be recommended.

Objective To investigate the efficacy and influential factors of 131I treatment for lung metastases from DTC.Methods Fifty patients (18 males,32 females;age (40.8±13.2) years) with lung metastases from DTC who underwent 131I treatment from October 2007 to December 2012 were retrospectively analyzed.The efficacy of 131 I treatment was assessed using 131I imaging and determination of serum Tg level after 6 months.The possible factors affecting efficacy included patients' age,gender,operation method,pathological classification,the diagnostic time of pulmonary metastasis,serum Tg level at diagnosis,131I uptake pattern,characteristics of other imaging modalities,cervical lymph node metastases and extrapulmonary distant metastases (assign 1 for metastases,0 for no metastases).Univariate and multivariate analyses (Student t test,Fisher exact test and logistic regression) were performed to investigate the factors.Results The rates of complete remission,partial response and invalid of 131I treatment were 20% (10/50),74% (37/50) and 26% (13/50) respectively.Univariate analysis showed that age(t =2.019,P<0.05),gender (P =0.032),serum Tg level at diagnosis (t =2.646,P< 0.05),findings of other imaging modalities (P =0.039),and extrapulmonary distant metastases(P=0.023) were the factors influencing outcome of 131I treatment.Multivariate logistic regression analysis showed that the influential factors included age,serum Tg levels and extrapulmonary distant metastases.The regression equation was as follows:logit P =2.127-0.056× age-0.163×Tg level-1.280×extrapulmonary distant metastasis (x2=10.484,P<0.001).Aged patients,a significant increase of Tg level and extrapulmonary distant metastases indicated a poor prognosis.Conclusions 131I treatment is an effective method for lung metastases from DTC.The patients with younger age,lower Tg levels,no other distant metastases had good response to 131I treatment.

ABSTRACT

Objective Midkine ( MK ) and nuclear factor-kappa B ( NF-kB ) play pivotal roles in tumorigenesis, which are considered as promising cancer biomarkers. The efficacy of MK and NF-kB as markers for diagnosis and prediction of synchronous metastasis in papillary thyroid cancer ( PTC ) was the aim of present investigation. Methods Seventy six cases of PTC and seventy cases of multi-nodular goiter ( MNG ) were retrieved. The PTC group was further divided into subgroup 1 (16 cases with synchronous metastasis) and subgroup 2 (60 cases without metastases). A retrospective review of clinical information, radiological examinations,131 I treatments and post-131 I-therapy scans were done. Immunohistochemistry of MK, NF-kB p65, and Ki-67 was performed on paraffin-embedded specimens and results were quantified. Diagnostic values of the parameters were conducted by receiver operating characteristic (ROC) curves. Diagnostic sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were determined. Protein levels of MK and NF-kB p65 were then confirmed by Western blot. Results Immunoreactivities of MK and NF-kB p65, and positive percentage of Ki-67 were significantly higher in PTC group than in MNG group (all P<0. 01). ROC showed good differential diagnostic capabilities of all three parameters with diagnostic accuracies of 82. 192% , 80. 137% , and 84. 091%respectively. Moreover, all three parameters were significantly higher in subgroup 1 than those in subgroup 2 (all P<0. 01). ROC showed good predicting efficacies in synchronous metastasis of all three parameters with diagnostic accuracies of 82. 895% , 80. 263% , and 76. 316% respectively. By one-way analysis of variance, Western blot showed that MK and NF-kB p65 protein levels in lesions from subgroup 1 were significantly higher than those from subgroup 2, both were significantly higher than those in MNG lesions ( P<0. 01). Conclusion MK and NF-kB immunohistochemistry can potentially be used for differential diagnosis between PTC and MNG, and for prediction of synchronous metastases.

ABSTRACT

Interdigitating dendritic cell sarcoma (IDCS)is a rare malignant tumor of the dendritic cell, derived from the hematopoietic tissue.The major clinical manifestation of IDCS is superficial lymphadenopathy, and the enlarged lymph nodes may appear in some atypical ereas,such as the lung,kidney,bladder and the pleura,etc.With the development of the pathological diagnosis and the application of immunohistochemical staining and electron microscopes,the case detection rate is apparently improved.With the high degree of malignant,rapid progress and poor prognosis of the disease,currently,surgical therapy is still the main approach to the treatment of IDCS.

ABSTRACT

<p><b>BACKGROUND</b>The prevalence of sleep disorders has been shown to be high in patients with chronic dialysis patients and may contribute to impaired quality of life and higher mortality in this population. However, there are few data on the relationship of sleep disorders and their risk factors in chronic dialysis patients. The aim of this study was to evaluate the relationship of sleep disorders and their risk factors in chronic dialysis patients.</p><p><b>METHODS</b>A total of 42 continuous ambulatory peritoneal dialysis (CAPD) patients were involved in this cross-sectional study. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Restless legs syndrome (RLS) was diagnosed according to the criteria of the International Restless Legs Syndrome Study Group. And depression was assessed by Hamilton depression scale. General information and laboratory data were collected.</p><p><b>RESULTS</b>The prevalence of sleep disorders was 47.6% in the CAPD patients. According to the PSQI, the 42 CAPD patients were divided into sleep disturbance group and non-sleep disorders group. There were no significant differences in age, gender, dialysis duration, hemoglobin, serum creatinine, urea nitrogen, β2-microglobulin, parathyroid hormone, calcium, and phosphorus between CAPD patients with sleep disorders and those without sleep disorders. But the level of serum albumin (Alb) in CAPD patients with sleep disorders was significantly lower than that in CAPD patients without sleep disorders (31.3 ± 1.4 vs. 34.3 ± 3.7, t = 3.603, P = 0.001) . And the prevalence of RLS and depression was significantly higher than that in CAPD patients without sleep disorders (RLS: 11/22 vs. 1/20, χ(2) = 10.395, P = 0.001; depression: 7/22 vs. 1/20, χ(2) = 4.886, P = 0.027). In CAPD patients with RLS, the prevalence of sleep disorders was significantly higher than that in CAPD patients without RLS (11/22 vs. 11/30, χ(2) = 10.395, P = 0.001). And in CAPD patients with depression, the prevalence of sleep disorders was significantly higher than that in CAPD patients without depression (7/8 vs. 15/34, χ(2) = 4.886, P = 0.027). In CAPD patients, bivariate correlation analysis showed that sleep disorders was negatively correlated with serum Alb (r = -0.606, P = 0.000) and positively correlated with RLS (r = 0.497, P = 0.001) and depression (r = 0.341, P = 0.029). Multivariate regression analysis revealed that the odds ratio of RLS, depression, and low serum Alb was 22.900, 42.209, and 0.597, respectively.</p><p><b>CONCLUSIONS</b>The prevalence of sleep disorders was relatively high in CAPD patients. RLS, depression, and low serum Alb were the risk factors for CAPD patients with sleep disorders.</p>

ABSTRACT

DTC in pediatric and adolescent patients has lower incidence and is generally reported to have better prognosis.However,compared with DTC in adults,it is more aggressive and the recurrence rate is higher.Surgery and adjuvant radioiodine therapy can minimize the risk of recurrence.Total or near total thyroidectomy combined with central compartment lymph node dissection is the preferred surgical procedure for most of these patients.Radioiodine therapy for ablation of thyroidal remnant or residual disease is recommended in order to reduce the risk of tumor recurrence,but there is slight chance of increased risk of a sec ond primary malignancy (SPM).Long-term follow-up is therefore recommended for the pediatrics and adolescents with DTC after treatment.Multi-disciplinary collaborative management is needed to optimize treatment efficacy and to minimize adverse effects.
