A Prospective Study Based on Spatial Multi-omics to Predict the Efficacy of ADT Combined With Second-generation Novel Hormonal Agents in Metastatic Hormone-sensitive Prostate Cancer.
2026年8月26日 更新者:Sheng Tai、Anhui Medical University
A Prospective Study Based on Spatial Multi-Omics for Predicting the Efficacy of Androgen Deprivation Therapy Combined With Second-Generation Novel Endocrine Therapeutic Agents in Metastatic Hormone-Sensitive Prostate Cancer.
This study plans to enroll patients with newly diagnosed metastatic hormone-sensitive prostate cancer (mHSPC) and conduct a prospective, single-center, observational study.
By performing whole-exome sequencing (WES), Xenium spatial transcriptomics, and PhenoCycler-Fusion spatial single-cell proteomics (PCF analysis) on tumor tissue samples, we aim to comprehensively delineate the molecular landscape of patients with different spatial multi-omic profiles in the real-world setting.
We will investigate the associations between these molecular features and differential treatment responses to various therapeutic regimens, and further construct predictive models of treatment response.
Ultimately, this will enable precise evaluation of treatment outcomes across distinct molecular subtypes and provide evidence to support individualized precision diagnostics and therapeutics for patients with mHSPC.

詳細な説明
1、Baseline sample collection: Tumor tissues will be collected via prostate biopsy from enrolled patients.
The specimens will be tripartite: one aliquot for standard histopathology, one for WES, and one for spatial multi-omic profiling (Xenium and PhenoCycler-Fusion).2、Follow-up: Patients will be assessed every 3 months during therapy, with CBC, biochemistry, sex hormones, and serum PSA.
Prostate mpMRI will be repeated every 3 months.
PSA testing frequency may be modified if PSA progression occurs.
Follow-up continues until CRPC development or death.3、(1)Primary:
Build a prognostic model integrating Xenium, WES, and PCF data.(2)Secondary:
bPFS and OS.(3)Progression: PSA rise to ≥0.2 ng/mL confirmed on repeat testing after prior undetectable levels.

実験的:Newly diagnosed mHSPC patients who meet the inclusion criteria
Eligible patients will be enrolled after providing written informed consent.
Individualized therapy (ADT plus abiraterone or other ARPIs) will be prescribed by the investigators according to each patient's financial situation, drug availability, and clinical needs, with regular follow-ups performed following routine real-world practice
|
The spatial heterogeneity of the tumor microenvironment in mHSPC-encompassing immune cell infiltration patterns, tumor-stroma interface features, and the regional activation status of critical signaling pathways-is intimately linked to clinical outcomes with ADT plus ARPI therapy.
Through comprehensive spatial multi-omic profiling, these spatial attributes can be systematically dissected to uncover pivotal predictive biomarkers, facilitate the development of accurate response prediction models, and ultimately guide personalized therapeutic strategies for patients with mHSPC
