Therapy of cancer with radiolabeled monoclonal antibodies has produced impressive results in preclinical experiments and in clinical trials conducted in radiosensitive malignancies, particularly B-cell lymphomas. Two "first-generation," directly radiolabeled anti-CD20 antibodies, (131)iodine-tositumomab and (90)yttrium-ibritumomab tiuxetan, were FDA-approved more than a decade ago but have been little utilized because of a variety of medical, financial, and logistic obstacles. Newer technologies employing multistep "pretargeting" methods, particularly those utilizing bispecific antibodies, have greatly enhanced the therapeutic efficacy of radioimmunotherapy and diminished its toxicities...

BACKGROUND Bridging treatments are employed in liver transplant waitlist patients with hepatocellular carcinoma (HCC) because of the risk of tumor progression during the waiting time. Radioembolization is mostly employed in the control of large or multifocal HCCs when other locoregional treatment modalities cannot be applied because of the number or size of lesions. The purpose of this study was to evaluate our experience with the use of radioembolization as a bridge to transplantation and its effect on tumor recurrence and survival after liver transplantation...

Brachytherapy is a type of radiotherapy wherein titanium capsules containing therapeutic radioisotopes are implanted within tumor tissues, enabling high-dose radio-irradiation to tumor tissues around the seeds. Although marked therapeutic effects have been demonstrated, brachytherapy needs complicated implantation technique under general anesthesia and the seeds could migrate to other organs. The aim of this study is to establish a novel brachytherapy using biocompatible, injectable thermo-responsive polymers (polyoxazoline; POZ) labeled with yttrium-90 ((90)Y), which can self-aggregate above a specific transition temperature, resulting in long-term intratumoral retention of radioactivity and therapeutic effect...

Selective internal radiation therapy (SIRT or radioembolisation) by intraarterial injection of radioactive yttrium-90 ((90) Y)-loaded microspheres is increasingly used for the treatment of patients with liver metastases or primary liver cancer. The high-dose beta-radiation penetrates an average of only 2.5 mm from the source so that its effects are limited to the site of delivery. However the off-target diversion of (90) Y microspheres to tissues other than the tumor may lead to complications. The most prominent ones include: radiation gastritis and gastrointestinal (GI) ulcers, cholecystitis, radiation pneumonitis, and radioembolisation-induced liver disease (REILD)...

Intrahepatic cholangiocarcinoma is increasing in frequency worldwide, but radical surgical treatment is practicable in 30-40% of cases. The median survival without therapy is about 8 months, increased to 12 months in combination with systemic chemotherapy. Therefore, locoregional therapies, such as, radiofrequency ablation or transarterial chemoembolization have been employed. Radioembolization with yttrium-90 microspheres ((90)Y-TARE) is a novel intrarterial treatment which could be included in the armamentarium of treatment options, having shown higher median survival (up to 22 months) and low complication rates...

OBJECTIVE: Studies investigating long-term health conditions in patients with craniopharyngioma are limited by short follow-up durations and do generally not compare long-term health effects according to initial craniopharyngioma treatment approach. In addition, studies comparing long-term health conditions between patients with childhood- and adult-onset craniopharyngioma report conflicting results. The objective of this study was to analyse a full spectrum of long-term health effects in patients with craniopharyngioma according to initial treatment approach and age group at craniopharyngioma presentation...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems...
