Clinical Application of 68Ga-FL-031 PET in the Diagnosis and Staging of Malignant Tumors

Summary

The project's objective is to recruit patients with clinically confirmed or suspected small cell lung cancer, breast cancer, nasopharyngeal carcinoma and other tumours for 68Ga-FL-031 PET imaging and 18F-FDG PET imaging. The histopathology of biopsy or surgical specimens was taken as the final diagnostic criteria, and the presence or absence of tumour lesions was confirmed by the aforementioned imaging. The location and nature of the lesion, and the presence or absence of metastasis, were then judged. The objective was to analyse and clarify the diagnostic efficacy of 68Ga-FL-031 PET imaging for the aforementioned malignant tumours. The objective of this study is to analyse the correlation between the 68Ga-FL-031 PET imaging tumour tissue uptake value and the tumour tissue immunohistochemical staining SSTR2 target expression.

3. Adult patients (aged 18 years or older), irrespective of gender
4. Patients with a clinical suspicion or confirmed diagnosis of small cell lung cancer, breast cancer, nasopharyngeal carcinoma, and other tumours (for which supporting evidence is provided in the form of serum-related tumour markers, ultrasound, CT, MRI and other image data, and histopathological examination)
5. The patient is generally in good condition
6. It is mutually agreed upon by all parties involved that the designated specimen shall be utilised for the purposes of this study.

Exclusion Criteria:
