Exploration of the Value of PSMA PET/CT in Dynamic Monitoring of the Efficacy of Novel Endocrine Therapy in Patients With Metastatic Hormone Sensitive Prostate Cancer

1. Based on the treatment response and prognosis of mHSPC patients with novel endocrine therapy, a PSMA PET whole-body tumor burden classification was constructed to guide treatment and evaluate prognosis. 2. Based on the treatment response and prognosis of mHSPC patients with novel endocrine therapy, a multivariable model will be constructed using quantitative parameters of PSMA PET/CT imaging, pre-treatment gene status, PSA, GS/ISUP and other clinical pathological parameters to further achieve accurate patient classification, guide treatment, and evaluate prognosis.
