Data collection and management will include a case record form (CRF) and electronic data management. The CRF will be used to record sample codes, sample type, number of tissue sections, laboratory assays, IHC/mIF results, image analysis results, and the minimum necessary clinicopathological information relevant to this study, including Gleason score, tumor stage, metastatic status, PSA level, lesion extent, or histological subtype. All samples and data will be coded or de-identified, and direct identifiers such as patient name, identification number, telephone number, or address will not be used in the research dataset. Electronic data will be managed using encrypted spreadsheets or an institutional secure data storage system. Data entry, verification, storage, and backup will be performed by designated research personnel. Access to the dataset will be restricted to authorized study members only, and the data will not be used beyond the approved scope of this study.
