[Place of molecular imaging in the management of prostate cancer].

In the management of prostate cancer in recent years, innovative therapies have appeared requiring precise and reliable disease detection. In 2021, new generation imaging (PET/CT, multiparametric MRI, PET/MRI) have their place at all stages of the prostate cancer natural history to help target the lesion(s) and guide therapy and improve the results obtained. PSMA PET/CT is currently the leader in this type of imaging with a complete offer during the disease: both from diagnosis, to recurrence or in the oligo-metastatic and metastatic stage resistant to castration with a pivotal role in the PSMA theranostic approach.

ARRONAX Cyclotron: Setting up of In-House Hospital Radiopharmacy.

Whilst radiopharmaceuticals have an important role to play in both imaging and treatment of patients, most notably cancer patients, nuclear medicine and radiopharmacy are currently facing challenges to create innovative new drugs. Traditional radiopharmaceutical manufacture can be considered as either a routine hospital production or a large-scale industrial production. The gap between these two practices has meant that there is an inability to supply innovative radiopharmaceuticals for use at the local level for mono- or multicentric clinical trials with satisfactory quality and safety specifications.

Preliminary results of a Ga-PSMA PET/CT prospective study in prostate cancer patients with occult recurrence: Diagnostic performance and impact on therapeutic decision-making.

Background: In this prospective study (NCT03443609), we investigated the impact of 68Ga-PSMA-11 PET-CT on the treatment plan and therapeutic response obtained for patients with prostate cancer (PCa) presenting a recurrence with a low rising PSA.

Methods: One hundred thirty hormone-naive (PSA < 1.5 ng/mL) patients were enrolled.

68Ga-PSMA-11 PET-CT study in prostate cancer patients with biochemical recurrence and non-contributive 18F-Choline PET-CT: Impact on therapeutic decision-making and biomarker changes.

Background: In this retrospective study, we investigated the impact of Ga-PSMA-11 PET-CT (PSMA PET-CT) upon the treatment plan and therapeutic response obtained for Prostate Cancer (PCa) patients presenting an occult biochemical recurrence.

Methods: Forty-two patients with previously negative or doubtful 18F-Choline (FCH) were enrolled. PET images were recorded 1 h after injection of tracer.

Radioimmunoconjugates for treating cancer: recent advances and current opportunities.

Radioimmunoconjugates have been used for 30 years to diagnose and treat cancer. For many years, the use of these therapeutic tools has been limited to haematological disorders, such as non-Hodgkin's lymphoma, given that they have only had a moderate effect on solid tumours. Areas covered: Recently, several strategies have revived the potential therapeutic application for radioimmunoconjugates.
