Although 18 F-FDG PET/CT is widely used in clinical practice, its diagnostic performance is limited in detecting small primary lesions, nodal metastasis, liver metastasis, and peritoneal carcinomatosis. Gallium-68 Fibroblast Activation Protein Inhibitor (FAPI) PET/CT is a novel imaging technology that targets cancer-associated fibroblasts, which are abundant in the desmoplastic stroma characteristic of biliary tract cancers. Early evidence suggests that FAPI PET/CT may provide improved lesion detectability and tumor-to-background contrast compared to FDG PET/CT.\n\nThis prospective observational study will evaluate the clinical utility of Ga-68 FAPI PET/CT for initial staging and suspected recurrence in patients with biliary tract cancers. Diagnostic performance metrics (sensitivity, specificity, PPV, NPV, and semi-quantitative PET parameters such as SUVmax and metabolic volume) will be assessed and compared with FDG PET/CT and/or follow-up imaging or histopathology as the gold standard. The study aims to determine the incremental diagnostic contribution of FAPI PET/CT and its potential impact on clinical decision-making.\n\nFindings from this research may help define the role of FAPI PET/CT as a complementary or alternative imaging modality in staging and restaging of biliary tract cancers and may support future prospective multicenter trials.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The study population will include adult male and female patients (≥18 years) with suspected or confirmed biliary tract cancers, including intrahepatic cholangiocarcinoma (iHCC) and gallbladder cancer (GBC).

It targets Fibroblast Activation Protein (FAP), which is highly expressed on cancer-associated fibroblasts within the tumor microenvironment in many epithelial malignancies, including biliary tract cancers. Ga-68 FAPI PET/CT provides high tumor uptake and improved tumor-to-background contrast, which may enhance detection of primary tumors, nodal disease, and distant metastases. It has demonstrated potential advantages over 18F-FDG PET/CT in sensitivity and diagnostic accuracy for staging and recurrence assessment.'}]}, 'contactsLocationsModule': {'locations': [{'zip': '400012', 'city': 'Mumbai', 'state': 'Maharashtra', 'status': 'RECRUITING', 'country': 'India', 'contacts': [{'name': 'Dr. Shraddha Patkar', 'role': 'CONTACT', 'email': 'drshraddhapatkar@gmail.com', 'phone': '+91 9820074818'}, {'name': 'Dr. Mahesh Goel', 'role': 'CONTACT', 'email': 'drmaheshgoel@gmail.com', 'phone': '+91 9820504492'}], 'facility': 'Dr.Shraddha Patkar', 'geoPoint': {'lat': 19.07283, 'lon': 72.88261}}], 'centralContacts': [{'name': 'Dr.Shraddha Patkar', 'role': 'CONTACT', 'email': 'drshraddhapatkar@gmail.com', 'phone': '+91 9820074818'}], 'overallOfficials': [{'name': 'Dr.Shraddha Patkar', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Tata Memorial Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Tata Memorial Centre', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
