E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Prostate adenocarcinoma accounts for 11% of all malignancies, with a total 2.6 million new cases / year estimated in Europe. Mortality rate is 30.6 / 100,000 persons/year. Prostate cancer generally evolves relatively slow and as a result of local growth, the tumor may infiltrate the closest pelvic structures ; besides the frequent metastatic involvement of pelvic lymph nodes, this cancer can metastasize through the bloodstream, with a marked preference for the skeleton. |
L’adenocarcinoma prostatico rappresenta l’11% di tutte le neoplasie maligne, con un’incidenza assoluta che in Europa viene stimata in 2,6 milioni di nuovi casi/anno e con una mortalità pari a 30,6/100 000 soggetti/anno. Il tumore della prostata ha in genere un’evoluzione relativamente lenta e può infiltrare le strutture pelviche adiacenti, oltre al frequente interessamento metastatico dei linfonodi pelvici, la metastatizzazione avviene per via ematogena con spiccata preferenza per lo scheletro. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
In this study we aim to evaluate sensitivity and specificity of [11C]-choline PET / CT in identifying the bone involvement in prostate cancer patients and to compare it with that of conventional imaging most largely used for this purpose (bone scan with technetium-99m oxidronate and/or CT scan). |
In pazienti con diagnosi di carcinoma prostatico, sia in fase di stadiazione che di sospetta ripresa di malattia, lo studio si propone di valutare sensibilità e specificità della [11C]-colina PET/TC nell’identificare il possibile coinvolgimento osseo e confrontarle con quello dell’imaging convenzionale routinariamente impiegato a questo scopo (scintigrafia ossea con tecnezio-99m ossidronato e/o TC). |

E.3 | Principal inclusion criteria |
Patients included must meet the inclusion criteria as follow:
we will enroll adult patients (aged>18years) with prostate cancer and suspected skeletal metastasis referring us at the “Nuclear Medicine Unit, IRCCS AOU San Martino - IST for specialist evaluation and that have signed the informed consent for study participation. |
I pazienti inseriti dovranno soddisfare i criteri di inclusione come segue:
verranno inclusi nello studio soggetti adulti (età>18anni) affetti da carcinoma prostatico con sospette secondarietà scheletriche giunti per consulto specialistico presso l’ Unità Operativa di Medicina Nucleare dell’IRCCS AOU San Martino – IST e che avranno firmato il consenso informato per la partecipazione allo studio. |
|
E.4 | Principal exclusion criteria |
The present study will not include healthy volunteers. Likewise, patients affected by conditions requiring emergency treatment, underage, mentally incapable or those who refuse to sign the informed consent will be excluded from the study. |
Saranno esclusi dallo studio volontari sani, minori, soggetti in situazioni di emergenza o non in grado di intendere e di volere, pazienti che si rifiutano di firmare il consenso informato. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
For each patient, the study provides three distinct moments (hereinafter time 1, time 2, time 3).
At Time 1 patients matching inclusion criteria are enrolled, sign informed consent, and consequently undergo PET / CT with [11C]-choline and convention imaging procedure (the time elapsed between the two examinations must not be greater than 30 days).
At time 2 results of PET / CT with [11C]-choline and conventional imaging are evaluated.
The time 3 provides, for each patient, the comparison of the results obtained by the two methods performed. In this study, each patient is the control of himself. |
Per ciascun paziente, lo studio prevede tre distinti momenti (di seguito denominati tempo 1, tempo 2, tempo 3).
Tempo 1: viene arruolato il paziente che soddisfa i criteri di inclusione, viene richiesta la firma del consenso informato e conseguentemente vengono eseguiti gli esami PET/TC con [11C]-colina e gli esami di imaging convenzionalmente eseguiti a questo scopo (il tempo intercorso tra i due esami non deve essere superiore a 30 giorni).
Tempo 2: avviene la valutazione dell’ esame PET/CT con [11C]-colina e quello dell’imaging convenzionale.
Tempo 3: confronto dei risultati ottenuti dalle due metodiche eseguite. In questo studio ogni paziente è controllo di se stesso. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The time elapsed between the two examinations must not be greater than 30 days. The comparison between the methods will be after the second examination. Duration of the study 2 years. |
Il tempo intercorso tra i due esami non deve essere superiore a 30 giorni. Il confronto tra le due metodiche applicate seguirà il secondo esame. Lo studio verrà valutato per 2 anni. |
