Abstract
Background To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) with 131iodine-doxorubicin-eluting gelatin microspheres (131I-DEM TACE) compared with conventional TACE (cTACE) with polyvinyl alcohol foam (PVA) embolization microspheres. Methods A total of 22 patients diagnosed with hepatocellular carcinoma were equally divided into 2 groups. The patients who underwent TACE with 131I-DEM (25.7×107 Bq of 131iodine and 10 mg of doxorubicin) were compared to controls who received cTACE with PVA embolization microspheres. Therapeutic effects were evaluated by the tumor regression rates, levels of alpha-fetoprotein in serum, survival rates, and complications. Results The operative complications of the 2 groups were not significantly different (P=0.753). The radioactivity ratio of the tumor to the liver was approximately 4.1:1 for the 131I-DEM TACE group. In the 131I-DEM TACE group, 54.5% of patients achieved tumor regression of more than 50%, compared to 36.6% of patients in the cTACE group. AFP levels in serum declined in 100% of patients in the 131I-DEM TACE group and 50% of patients in the cTACE group. The median survival time of the patients was 12.0±3.3 months for the 131I-DEM TACE group and 10.0±3.3 months for the cTACE group. There were no significant differences in survival between the 2 groups (P=0.414). Conclusions 131I-DEM may become a potential radiochemoembolization agent to treat patients with unresectable hepatocellular carcinoma through TACE.

Abstract
Chimeric antigen receptor (CAR) T cell therapies, and adoptive cell therapy (ACT) in general, represent one of the most promising anti-cancer strategies. Conditioning has been shown to improve the immune homeostatic environment to enable successful ACT or CAR-T engraftment and expansion in vivo following infusion, and represents potential point of intervention to decrease serious toxicities following CAR-T treatment. In contrast to relatively non-specific chemotherapy-derived lymphodepletion, targeted lymphodepletion with radioimmunotherapy (RIT) directed to CD45 may be a safer and more effective alternative to target and deplete immune cells. Here we describe the results of preclinical studies with an anti-mouse CD45 antibody 30F11, labeled with two different beta-emitters 131Iodine (131I) and 177Lutetium (177Lu), to investigate the effect of anti-CD45 RIT lymphodepletion on immune cell types and on tumor control in a model of adoptive cell therapy. Treatment of mice with 3.7 MBq 131I-30F11 or 1.48 MBq 177Lu-30F11 safely depleted immune cells such as spleen CD4+ and CD8+ T Cells, B and NK cells as well as Tregs in OT I tumor model while sparing RBC and platelets and enabled E. G7 tumor control. Our results support the application of CD45-targeted RIT lymphodepletion with a non-myeloablative dose of 131I-30F11 or 177Lu-30F11 antibody prior to adoptive cell therapy.

Abstract
Our previous studies demonstrated the cytogenetic effects in the peripheral blood lymphocytes of a 34-year-old male patient who received ablative radioactive 131iodine therapy (RIT) on two different occasions in 1992 and 1994. Assessment of RIT-induced chromosomal damage by the cytokinesis-blocked micronucleus assay (CBMN) showed the persistence of elevated micronucleus frequency in this patient for more than two decades since the first RIT. Subsequent cytogenetic analysis performed in 2012 revealed both stable and unstable aberrations, whose frequencies were higher than the baseline reported in the literature. Here, we report the findings of our recent cytogenetic analysis peformed in 2015 on this patient using the multicolor fluorescence in situ hybridization (mFISH) technique. Our results showed that both reciprocal and non-reciprocal translocations persisted at higher frequencies in the patient than those reported in 2012. Persistence of structural aberrations for more than two decades indicate that these aberrations might have originated from long-lived T-lymphocytes or hematopoietic stem cells. Our study suggests that the long-term persistence of chromosome translocations in circulating lymphocytes can be useful for monitoring the extent of RIT-induced chromosomal instability several years after exposure and for estimating the cumulative absorbed dose after multiple RITs for retrospective biodosimetry purposes. This is perhaps the first and longest follow-up study documenting the persistence of cytogenetic damage for 21 years after internal radiation exposure.

Abstract
(131)Iodine is used both to ablate any residual thyroid tissue or metastatic disease and to obtain whole-body diagnostic images after total thyroidectomy for differentiated thyroid cancer (DTC). Even though whole-body scan is highly accurate in showing thyroid residues as well as metastases of DTC, false positive results can be found, possibly leading to diagnostic errors and unnecessary treatments. This paper reviews the physiological and pathological processes involved as well as the strategy to recognize and rule out false positive radioiodine images.

Abstract
BACKGROUND The effect of feeding a limited iodine diet on radioactive iodine uptake in the thyroid glands of hyperthyroid cats is unknown. OBJECTIVES To determine how feeding limited dietary iodine affects radioactive iodine uptake by the thyroid glands of hyperthyroid cats. ANIMALS Eight geriatric cats with spontaneous hyperthyroidism. METHODS Prospective study of eight client owned hyperthyroid cats fed a commercially available iodine limited diet for 6 months. Clinical signs were evaluated and TT4 and fT4 were measured during consumption of the diet. Uptake of (123)I was determined before and 8-16 weeks after exclusive consumption of the diet. RESULTS Clinical signs of hyperthyroidism resolved in all cats, but there was no significant increase in body weight. TT4 and fT4 decreased into the reference range by 8-16 weeks in all cats. Mean TT4 before consumption of the diet was 9.7 μg/dL (SD 5.2) and after consumption of the diet was 3.1 μg/dL (SD 0.9). Scintigraphy revealed unilateral uptake of isotope in 5 cats and bilateral uptake in 3 cats. Mean percentage uptake of (123)I by the thyroid gland at 8 hours after isotope administration was 16.2 (SD 11.8) before diet consumption and 34.6 (SD 11.7) 8-16 weeks after exclusive consumption of the diet. The percentage increase was variable between cats (38-639%). CONCLUSIONS AND CLINICAL IMPORTANCE Limited iodine diets increase iodine uptake in the autonomous thyroid glands of hyperthyroid cats. Further studies are necessary to determine if consumption of a limited iodine diet changes sensitivity of the thyroid gland to (131)I treatment.

Abstract
A 48-year-old woman undergoing surgery could not be intubated because of an oropharyngeal mass. CT and MRI revealed a 3 cm possible lingual thyroid mass, confirmed by Iodine-123 SPECT/CT. The patient underwent successful Iodine-131 ablation and has done well on thyroid hormone-replacement therapy. This case also demonstrates how modern cross-sectional imaging like SPECT/CT can appropriately be used in the patient diagnosis and management, and is of additional interest for including pre- and post-therapy MRI documenting efficacy morphologically.

Abstract
The aim of this study was to evaluate the radioprotective effect of turmeric extract (40 mg/kg body weight) and vitamin E (α- tocopherol acetate, 400 IU/kg body weight) supplementation on lipid peroxidation, reduced glutathione and antioxidant defense enzymes in various organs like liver, kidney and salivary glands at 24 h in adult Swiss mice. (131)Iodine exposure significantly increased lipid peroxidation in kidney and salivary glands in comparison to control animals. Pre supplementation with turmeric extract for 15 days showed significant lowering of lipid peroxidation in kidney. On the other hand vitamin E pre supplementation showed marked reduction in lipid peroxidation in salivary glands. Reduced glutathione levels decreased significantly in liver after radiation exposure. However, pre supplementation with turmeric extract and vitamin E did not improve glutathione levels in liver. In conclusion, we have observed differential radioprotective effect of turmeric extract and vitamin E in kidney and salivary glands. However, Vitamin E seems to offer better radioprotection for salivary glands which is known to be the major site of cellular destruction after radioiodine therapy in patients.
