Conditions
Summary
This is a prospective, open-label, single-center clinical study targeting renal cell carcinoma. Sixty patients with a high clinical suspicion of renal cell carcinoma were included. Qualified subjects will undergo 68Ga-NOTA-RCCB6 PET/CT examination. The aim is to establish the optimal imaging protocol; evaluate the distribution characteristics and correlations of physiological and pathological positive uptake, and using pathological results as the gold standard, assess the diagnostic efficacy of 68Ga-NOTA-RCCB6 PET/CT in renal cell carcinoma.
Eligibility
Inclusion Criteria4
- \- The subject or legal guardian/caregiver must voluntarily sign the informed consent form.
- Ages 18 to 75 years old. Patients with suspected renal cell carcinoma based on conventional imaging studies, and who undergo 68Ga-PSMA PET/CT scanning.
- Patients with suspicious lymph nodes or distant metastases detected by conventional imaging or 68Ga-PSMA PET/CT.
- Willing and able to follow the study protocol.
Exclusion Criteria4
- \- Patients who have received anti-tumor treatment prior to PET/CT scan. Suffer from severe other neurological diseases, or gastrointestinal, cardiovascular, liver, kidney, blood system, respiratory system, immunodeficiency and other serious diseases.
- Alternative subjects have contraindications to PET/CT scanning. Including but not limited to: those who cannot tolerate repeated intravenous injections; those who may be allergic to the drug and its components (including those with a history of severe allergies or allergic reactions, especially those with allergies to the tested drug); claustrophobia.
- In the past year, diagnosed with other malignant tumors; alternative subjects have undergone major surgery in the past 3 months; received experimental drug or device treatment with unclear effects or safety within the past month, or have participated in other interventional clinical trials.
- Pregnant or lactating women. Patients who are lost to follow-up. Other conditions that, in the researcher's assessment, may affect the study or make the subject unsuitable for participation in the study.
Interventions
The imaging agent 68Ga-NOTA-RCCB6 used in this project is synthesized following the standards for radiopharmaceutical production, with reference to the Chinese Pharmacopoeia (quality standards for 18F-FDG). The pH value is between 5.0 and 8.0; the radiochemical purity is not less than 95%, and the bacterial endotoxin content in each milliliter of solution is less than 15EU; the radioactive concentration is not less than 37 MBq/mL; the solvent residues comply with the regulations. Specification: 185\~1850 MBq/ml Characteristics: Clear, colorless, no visible particles. Radioactive physical half-life: 68Ga is 68 minutes. Expiry: Calculated from the time of labeling, stable for 3 half-lives. Administration method: Intravenous injection. Dosage: 0.05-0.1mCi/kg, flush with 5 mL of saline after injection. The maximum mass dose of CD70 should not exceed 240ug, and the maximum volume of administration should not exceed 5 mL.
