The epidermal growth factor receptor antibody cetuximab is an attractive option, if it is able to cross the blood-brain barrier. This might be proven with molecular imaging if the radiolabeled antibody is stable long enough to be effective. This study investigated the stability of radiolabeled cetuximab (Erbitux) ((131)I-Erbi) and potential synergistic effects with radiotherapy in vitro. Methods and Materials: Two cell lines were investigated, A431 with numerous epidermal growth factor receptors, and JIMT without epidermal growth factor receptors. We labeled 0.4 mg cetuximab with 50 MBq of [(131)I] iodide. Stability was determined for 72 h. The cell cultures were incubated with (131)I-Erbi or cold cetuximab for 72 h. Uptake and cell proliferation were measured every 24 h after no radiotherapy or irradiation with 2, 4, or 10 Gy. Results: The radiolabeling yield of (131)I-Erbi was always >80%. The radiochemical purity was still 93.6% after 72 h. A431 cells showed a (131)I-Erbi uptake about 100-fold greater than the JIMT controls. After 48 h, the A431 cultures showed significantly decreased proliferation. At 72 h after irradiation, (131)I-Erbi resulted in more pronounced inhibition of cell proliferation than the cold antibody in all radiation dose groups. Conclusion: (131)I-Erbi was stable for <= 72 h. Radiotherapy led to increased tumor cell uptake of (131)I-Erbi. Radiotherapy and (131)I-Erbi synergistically inhibited tumor cell proliferation. These results provide the prerequisite data for a planned in vivo study of whole brain radiotherapy plus cetuximab for brain metastases.

Patients, methods: In 91 consecutive patients with DTC UIE, measured as iodine/creatinine ratio, was determined before and after application of I-123 and I-131 for diagnostic or therapeutic purposes. Additionally, remnant volume (V) was determined prior to therapy. Group A consisted of 33 patients with supposed successful ablation of DTC. These patients received 370 MBq I-131 for diagnostic use and served as controls. 58 patients (group B) with remnants, relapses and metastases received 370 MBq I-123 for diagnostics prior to therapy with 1.5-22.2 GBq I-131. Factors influencing individual changes in urinary iodine excretion (Delta UIE) were investigated by using non-parametric tests. Results: In group A WE did not change significantly after application of I-131. As well, UIE remained unchanged after diagnostic application of I-123 in group B. In contrast, UIE increased significantly already 24 h after therapeutic application of I-131 in this group. In patients with small remnants (V < 2.5 ml) a significant but only moderate increase of WE could be observed (average increase: 47 mu g l/g crea). In patients with larger remnants, with relapses or metastases increase of UIE values was significant and more pronounced. Conclusions: It was confirmed that UIE increased significantly during radioiodine therapy in patients with DTC and radioiodine-accumulating tissue. The increase of WE after therapeutic administration of radioiodine can be explained by the disintegrated thyroid follicles in thyroid remnants. The radioiodine-induced iodine release may be one reason for thyroid \"stunning\" even after application of diagnostic amounts of I-131."],["dc.identifier.isi","000234213400004"],["dc.identifier.pmid","16400384"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/20291"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Schattauer Gmbh-verlag Medizin Naturwissenschaften"],["dc.relation.issn","0029-5566"],["dc.title","Diagnostic I-121 and I-131 activities and radioiodine therapy - Effects on urinary iodine excretion in patients with differentiated thyroid carcinoma"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Some days after application of I-131, the uptake of a subsequent administration of radioiodine was found to be reduced. In contrast, early after irradiation with high-energy photons glucose and amino acid uptake were observed to be increased. Effects of external irradiation on RIU of thyrocytes using high-energy photons have not been investigated so far. Material and Methods: Two different cell lines (FRTL-5 and ML-1 cells) derived from thyroid tissue were studied in vitro. Cell Lines were either incubated with I-131 only (controls) or additionally irradiated with single doses of 6 or 10 Gy of high-energy photons using a linear accelerator. Cell number and RIU were determined 24-96 h after I-131 application. RIU measurements were repeated after application of sodium perchlorate in excess to investigate specificity of the uptake. Statistical analyses were performed using non-parametric tests. Results: Incubation with radioiodine as well as irradiation with high-energy photons slowed down proliferation in investigated cell lines significantly. Irradiation with solely I-131 resulted in stable or slightly decreased iodide uptake. Compared to those cells, the RIU increased significantly in externally irradiated cells, i.e., additional irradiation with 10 Gy resulted in an almost threefold increase of RIU in FRTL-5 after 72 h. The increase of RIU after irradiation was dose-dependent in both cell lines and could be blocked by perchlorate excess. Conclusion: It could be demonstrated that external irradiation increases RIU in thyroid cell cultures early after irradiation. The increase was dose-dependent and specific, as it could be blocked by perchlorate. This effect appears to be similar to the increase of other actively transported substances after irradiation with high-energy photons. Therefore, the results of this study may contribute to the knowledge of a generalized irradiation-induced mechanism which causes the activation of different cellular transporters. The clinical impact of these findings on combined therapy concepts has to be investigated in further experiments."],["dc.identifier.doi","10.1007/s00066-006-1442-y"],["dc.identifier.isi","000234943400005"],["dc.identifier.pmid","16404518"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/46857"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Urban & Vogel"],["dc.relation.issn","0179-7158"],["dc.title","Increased radioiodine uptake of thyroid cell cultures after external irradiation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
