Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
2. Research background Prostate cancer is the most common malignant tumor of the urinary system. Current diagnostic tools for prostate cancer include serum prostate-specific antigen (PSA) test, transrectal prostate aspiration biopsy, etc. However, these tools are often invasive. When a patient's PSA rises again after radical prostatectomy for prostate cancer, conventional CT, MRI, and bone scintigraphy do not have a high detection rate (11%); Although multiparametric magnetic resonance imaging (mpMRI) is of undisputed importance in the T-staging of tumors, it has limited diagnostic accuracy when applied alone and is less sensitive in the diagnosis of local lymph node metastases. Currently, PET/CT has been gradually applied to different types and stages of prostate cancer. With the popularity of integrated PET/MR imaging, combining the higher resolution and morphological performance of MR imaging with the N-staging and M-staging of PET, the specificity of primary prostate cancer diagnosis can be greatly improved.
Currently, the commonly used targeted tracers for PET examination of prostate cancer include 18F-fluorodeoxyglucose (18F-FDG), and 18F-/11C-acetate, etc., but their imaging effects are not up to the ideal level. PSMA is located in prostate epithelial cells and is converted to a membrane-bound protein in prostate cancer, and PSMA expression is approximately 100 to 1000 times higher in prostate cancer tissue compared to normal prostate tissue. PSMA is expressed at high levels in 95% of prostate cancer patients and is upregulated in castration-resistant prostate cancer (CRPC) and metastatic prostate cancer. PSMA expression was also increased after androgen deprivation therapy (ADT). The use of 68Ga-labelled PSMA small molecule inhibitors can be specifically combined with prostate cancer cells, and it is important for the diagnosis of prostate cancer and its metastatic foci through PET/CT and PET/MR visualization. 68Ga-PSMA 617 was first applied to prostate cancer patients in 2015, Afshar-Oromieh et al. conducted the first evaluation of the human biological distribution, radiation dose of this contrast agent and found that there was uptake in the kidney and salivary glands, and the detection rate of prostate cancer lesions was 73.7% (14/19). The best imaging results were obtained 2-3 h after injection, with an average radiation dose of about 0.021 mSv/mbq.
3. Research purpose This study is expected to be used for prostate cancer occurrence and recurrence, early specific identification and localization of tumor foci at the molecular level, and evaluation of patient prognosis. Not only can it accurately stage first-time intermediate- and high-risk prostate cancer patients, but it can also detect recurrent lesions in biochemically recurrent patients. Those who develop metastases are restaged to assess tumor load and ultimately assist in determining a personalized treatment plan.
4. Type of study design, method of randomization and level of blinding Type of study design: observational study (prospective study)

10. Subject screening numbers, subject numbers, and case report forms are maintained Participant Screening Number: a 1-sequential number, e.g., 1-1 for the first participant; participant Number: a sequential number, e.g., 001 for the first participant; Case report form retention: information is entered into the CRF form by the project leader or other authorized investigator, and only medically qualified investigators are allowed to complete the original clinical assessment/safety data. Any changes made to the CRF form by the project leader or other authorized researchers after the original data has been entered need to be documented. Any modification of data that has been endorsed will require the name of the researcher or other authorized researcher who made the modification, the date of the modification, and the reason for the modification (if the change is minor).
11. Documentation of adverse events and methods of reporting serious adverse events, management measures, modalities, timing and regression of follow-up visits.
11.1 Adverse events Adverse Event (AE) is an unfavorable medical event that occurs during a clinical trial. Clinical trial Any adverse event that occurs during the implementation should be faithfully recorded and analyzed for reasons. Both anticipated and unanticipated adverse events should be be recorded and reported truthfully. Adverse events should be included as outcome variables in the statistical analysis of clinical trials.
11.2 Serious adverse event A serious Adverse Event (SAE) is a clinical trial event that results in death or serious deterioration of health, including fatal illness or injury, permanent defects in body structure or function, hospitalization or prolonged hospitalization, or the need for medical or surgical intervention to avoid permanent defects in body structure or function. Events that result in fetal distress, fetal death, or congenital anomalies or congenital defects.
11.3 Reporting procedures 11.3.1 Reporting time frames In the event of AE or SAE in this clinical trial, the investigator shall immediately take appropriate therapeutic measures for the participant, notify the principal investigator, and report in writing to the appropriate authorities within 24 hours once SAE has been determined.
11.3.2 Reporting Sector The office of the clinical trial organization to which it belongs, the sponsor, our Ethics Committee, as well as the drug supervision and management department of the province, autonomous region, and municipality directly under the central government where the clinical trial organization is located, and the competent department of health and wellness.
11.3.3 Reporting methods If an SAE occurs, the investigator completes the Adverse Event Record Form and files the original Adverse Event Record Form in the investigator's file folder.
11.3.4 Processing and recording When an SAE or suspected SAE occurs, the investigator immediately stops the trial and takes appropriate therapeutic measures, notifies the principal investigator and the sponsor; the principal investigator makes a judgment about the relevance of the SAE to the trial and records the occurrence, development, and treatment of the SAE in as much detail as possible on the Adverse Event Record Form, which is documented on the Case Report Form, signed and dated.
11.3.5 follow-up If SAE is determined, the event must be followed until it appears to improve, stabilizes, or, in the judgment of the principal investigator, does not require follow-up.
12. Statistical analysis plan, definition, and selection of data sets for statistical analysis 12.1 General approach SPSS software was used for statistical analysis of data. If the data were normally distributed, they were expressed as mean ± standard deviation and compared using a two-sample t-test and one-way ANOVA. If the data were not normally distributed, they were expressed as M(P5, P95) and compared using the Mann-Whitneyu and Kruskal-WallisH rank sum tests. P\<0.05 is considered a statistically significant difference.
12.2 Analysis of primary and secondary study endpoints Survival analysis was performed using the Kaplan-Meier method to plot survival curves, and the log-rank test was used to compare survival differences between groups.
13. Data management and confidentiality of information 13.1 Data entry and modification Data entry and modification will be done by the Department of Nuclear Medicine, and data collection will be performed by clinical researchers under the supervision of the person in charge, who will be responsible for the accuracy, completeness, and timeliness of the reported data. All data should be clear to ensure accurate interpretation and to guarantee its traceability. Clinical data will be maintained in a database, which should be password-protected, and a logical proofreading process should be in place when the database is created.
The Data Manager is responsible for reviewing and managing the entered data. In case of doubt about the existence of data, the data manager will send the appropriate query to the researcher, who will respond to the query sent by the data manager in a timely manner, and the data manager will be able to re-question the data if necessary.
13.2 Confidentiality Program for Research Participant Information Participants' personal information follows the principle of confidentiality. The investigator will replace the participants' identifying information with a code name that does not contain his/her name.
