Article Synopsis
  • Gallium-68-labeled FAPI-46 has emerged as a new PET imaging agent for diagnosing various cancers, creating a high demand due to encouraging clinical trial results.
  • Current labeling protocols struggle with processing multiple elutions from gallium-68 generators, hindering production scalability.
  • The proposed automated radiosynthesis method optimizes prepurification to achieve over 89% radiochemical yield while maintaining high purity, making it compatible with different generator brands.

Objectives: The risk of chronic exposure to antineoplastic agents in hospitals, mainly by skin contact with contaminated surfaces, is well established. The aim of this study was to assess indirectly the risk of occupational exposure to antineoplastics drugs at two hospitals by using an environmental monitoring, and to suggest ways of improving the exposure to healthcare workers.

Methods: An observational study of care practices on both sites was carried out.

The radiochemical purity (RCP) determination of radiopharmaceuticals is routinely done with radio-thin layer chromatography (r-TLC). These methods are usually transposed and adjusted from the summary product characteristics without any analytical validation. The r-TLC method is simple but manually-performed steps could lead to RCP misinterpretation.

Objectives: In France, dispensation is defined by the validation of a prescription associated with a pharmaceutical analysis, preparation of medication and provision of information necessary for proper use. There are very few data available in the literature that describe prescription analysis modality in radiopharmacy. The aim was to secure a place for paediatric prescription analysis in radiopharmacy by designing a flow chart validated by experts.

A patient enrolled in a clinical trial (NCT02802969) with suspicion of chordoma underwent an [F]FAZA PET/CT, a radiolabeled nitroimidazole analog of hypoxia PET imaging. The patient's images showed a different tumor profile compared to those observed in other hypoxic or nonhypoxic chordoma patients. The motivation for using [F]FAZA pharmacokinetic imaging was to compare this profile with histologically confirmed cases of chordoma.

The main objective of the present work was to ensure quality of radiopharmaceuticals syringes withdrawn with a "Spinal needle/obturator In-Stopper" system. Visual examinations and physicochemical tests are performed at T0 and T+4h for [Tc]albumin nanocolloid and T+7h for [Tc]eluate, [Tc] HydroxyMethylene DiPhosphonate and [Tc]Human Serum Albumin. Microbiological validation was performed according to European pharmacopoeia.

Purpose: The purpose of this pilot study was to assess whether outcome in metastatic or recurrent breast cancer patients is related to metabolic response to endocrine therapy determined by (18)F-FDG PET/CT.

Methods: The study group comprised 22 patients with breast cancer (age 58 ± 11 years, mean ± SD) who were scheduled to receive endocrine therapy. They were systematically assessed by PET/CT at baseline and after a mean of 10 ± 4 weeks for evaluation of response after induction.

Hybrid systems associating the sharpness of anatomic images coming from computed tomography (CT) and radionuclide functional imaging (SPET or PET) are opening a new era in oncology. This multimodal imaging method is now routinely used for the diagnosis, extent, follow up, treatment response and detection of occult disease in different types of malignancies with a significant impact on the treatment strategy leading for a change for more than 68% of all investigated patients.

Background: Breast cancer recurrence is often suspected on tumor marker rising in asymptomatic patients. The value of fluorine-18 fluorodeoxyglucose (18FDG)-positron emission tomography/computed tomography (PET/CT) imaging to detect recurrence and its subsequent impact on patient management were retrospectively assessed.

Methods: PET/CT scans were performed on 228 asymptomatic patients (mean, 60.
