<b>Objective:</b> This study aimed to evaluate the prognostic value of the SUVmax-IPI composite score, generated by integrating the maximum standardized uptake value (SUVmax) derived from metastatic <sup>68</sup>Ga-PSMA PET/CT imaging with the inflammatory prognostic index (IPI), in predicting overall survival in patients with metastatic prostate cancer. This evidence concerns the gene FOLH1 and metastatic prostate carcinoma.
