Descrição detalhada
This study will utilize tissue specimens and clinical follow-up data from prostate cancer patients, integrating HE/WSI pathological images, spatial transcriptomics, spatial proteomics, whole-exome sequencing (WES), and single-cell transcriptomics to systematically characterize the cellular composition, spatial proximity relationships, molecular expression profiles, and genomic alterations within the perineural invasion (PNI) microenvironment of prostate cancer.
Specifically, this study aims to delineate the spatial multi-omics differences among PNI-positive regions, PNI-negative tumor regions, and adjacent-normal regions; to screen for candidate molecular markers associated with PNI burden, local tumor aggressiveness, and poor postoperative outcomes; and to explore the establishment of a PNI classification and prognostic risk assessment model based on spatial multi-omics features, thereby providing a foundation for individualized risk stratification and future mechanistic investigations in prostate cancer.

Descrição
Inclusion Criteria:
（1）Age >18 years and <85 years. （2）Histopathologically confirmed prostate cancer, including prostatic acinar adenocarcinoma, ductal adenocarcinoma, intraductal carcinoma, or other pathological types deemed suitable for inclusion by the investigator.
（3）Have undergone radical prostatectomy, prostate biopsy, or other clinical diagnostic or therapeutic procedures, and have prostate tissue specimens obtained and available for research purposes.
（4）Tissue specimens meet the basic quality requirements for HE pathological assessment, spatial transcriptomics, spatial proteomics, whole-exome sequencing (WES), or single-cell transcriptome sequencing.
（5）Have available basic clinical data, pathological data, treatment information, and follow-up data, including PSA levels, pathological grade, pathological stage, margin status, perineural invasion (PNI) status, and postoperative re-examination information.
（6）For prospectively enrolled new patients, written informed consent must be voluntarily signed. For archived leftover specimens and medical records obtained during prior clinical care, a waiver of informed consent or waiver of documentation of informed consent may be applied for, provided that ethical requirements are satisfied.
Exclusion Criteria:
（1）Insufficient tissue sample quantity, severe disruption of tissue architecture, excessively low tumor cellularity, or nucleic acid/protein quality that fails to meet the requirements for the intended assays.
（2）Severe deficiency in clinicopathological data, precluding the determination of perineural invasion (PNI) status, major pathological parameters, or key follow-up outcomes.
（3）Concurrent other malignancies that, in the investigator's judgment, may significantly affect the prognostic assessment of prostate cancer.
（4）The patient explicitly refuses to allow their samples or clinical information to be used for scientific research.
（5）Other conditions deemed unsuitable for inclusion in this study by the investigator.

Biochemical Progression-Free Survival (bPFS)
Prazo: From treatment initiation until biochemical progression or last follow-up, assessed every 3 months (+1 month) for up to 24 months.
|
Time from initiation of ADT plus ARPl therapy to biochemical progression or deathfrom any cause, whichever occurs first.
Biochemical progression is defined as a PSA rise to a0.2ng/mL after having reached an undetectable level, confirmed by a second measurement at least 2weeks apart.
Participants without an event will be censored at the date of last follow-up.

From treatment initiation until biochemical progression or last follow-up, assessed every 3 months (+1 month) for up to 24 months.
