E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The study aims to evaluate the accuracy of PET / CT with 68Ga-FAPI in detecting the presence of disease in patients for whom, upon completion of the clinical and instrumental diagnostic procedures required by their normal care path, the diagnostic doubt remains: examination PET / CT with 18F-FDG resulted doubtful for the presence of oncological disease or inconclusive in satisfying this diagnostic question. |
Lo studio si propone di valutare l’accuratezza della PET/TC con 68Ga-FAPI nel rilevare la presenza di malattia in pazienti per i quali, al completamento delle procedure diagnostiche cliniche e strumentali previste dal loro normale percorso assistenziale, permanga il dubbio diagnostico: esame PET/TC con 18F-FDG risultato dubbio per la presenza di malattia oncologica o inconcludente nel soddisfare tale quesito diagnostico. |

E.5 End points |
E.5.1 | Primary end point(s) |
Accuracy of PET / CT with 68Ga-FAPI in detecting the presence of disease in patients for whom, upon completion of the clinical and instrumental diagnostic procedures required by their normal care pathway, the diagnostic doubt remains: PET / CT examination with 18F-FDG result doubt for the presence of oncological disease or inconclusive in satisfying this diagnostic question. The findings will be evaluated as positive (PET FAPI +) if the SUVmax of the radiopharmaceutical in a specific VOI that fully includes the lesion is> the SUVmean of the background (surrounding tissues) which will be calculated in a VOI of 1 cm 10 min after administration. The findings will be judged negative (PET FAPI-) if they do not show uptake of the radiopharmaceutical or an uptake lower than the surrounding background (SUVmax doubtful finding / SUVmean of the background =1. The results of the PET / CT survey with 68Ga-FAPI will be evaluated as TRUE POSITIVE / FALSE POSITIVE / TRUE NEGATIVE and FALSE NEGATIVE based on the result of the histological examination if available otherwise based on the comparison with the follow-up investigations over 12 months following the experimental investigation. The accuracy of PET / CT with 68Ga-FAPI will be calculated with the following statistical formula: (TRUE POSITIVE + TRUE NEGATIVE) / TOTAL PATIENTS |
Accuratezza della PET/TC con 68Ga-FAPI nel rilevare la presenza di malattia in pazienti per i quali, al completamento delle procedure diagnostiche cliniche e strumentali previste dal loro normale percorso assistenziale, permanga il dubbio diagnostico: esame PET/TC con 18F-FDG risultato dubbio per la presenza di malattia oncologica o inconcludente nel soddisfare tale quesito diagnostico. I reperti verranno valutati come positivi (PET FAPI+) se il SUVmax del radiofarmaco in una VOI specifica che include interamente la lesione è > del SUVmean del background (tessuti circostanti) che verrà calcolato in una VOI di 1 cm a 10 min dalla somministrazione. I reperti verranno giudicati negativi (PET FAPI-) se non presenteranno captazione del radiofarmaco ovvero una captazione inferiore al background circostante (SUVmax reperto dubbio/SUVmean del background =1. I risultati dell’indagine PET/TC con 68Ga-FAPI verranno valutati come VERI POSITIVI/ FALSI POSITIVI/ VERI NEGATIVI e FALSI NEGATIVI sulla base del risultato dell’ esame istologico se disponibile altrimenti sulla base del confronto con le indagini di follow up nei 12 mesi successivi all’indagine sperimentale. L’accuratezza della PET/TC con 68Ga-FAPI verrà calcolata con la seguente formula statistica: (VERI POSITIVI+VERI NEGATIVI)/TOTALE PAZIENTI |

Findings will be evaluated as positive (PET FDG-) if the radiopharmaceutical SUVmax in a VOI that fully includes the lesion is = 2.
The results of PET / CT investigations with 68Ga-FAPI and 18F-FDG will be evaluated as TRUE POSITIVE / FALSE POSITIVE / TRUE NEGATIVE and FALSE NEGATIVE based on the result of the histological examination if available otherwise based on the comparison with the follow up investigations in the 12 months following the experimental investigation. The accuracy of PET / CT with 68Ga-FAPI and with 18F-FDG will be calculated with the following statistical formula: (TRUE POSITIVE + TRUE NEGATIVE) / TOTAL PATIENTS The sensitivity of PET / CT with 68Ga-FAPI and with 18F-FDG will be calculated with the following statistical formula: TRUE POSITIVE / (TRUE POSITIVE + FALSE NEGATIVE) The specificity of PET / CT with 68Ga-FAPI and with 18F-FDG will be calculated with the following statistical formula: TRUE NEGATIVE / (TRUE NEGATIVE + FALSE POSITIVE) Then the accuracy, sensitivity and specificity calculated for PET / CT with 68Ga-FAPI and 18F-FDG PET / CT will be compared. |
