Methods: A retrospective collection and analysis of clinical data from 169 prostate cancer patients were conducted. Based on the results of bone scans supplemented by MRI, patients with or without pelvic bone metastasis were divided into the prostate cancer bone metastasis group (80 cases) and the non-bone metastasis group (89 cases). All patients underwent MRI examination prior to surgery, and serum levels of PSA, ALP, D-dimer, and FIB were quantitatively measured. Kappa consistency tests were used to analyze the agreement between different imaging indicators and the results of prostate cancer bone metastasis. Uni- and multivariable logistic regression analyses were performed to evaluate the value of mpMRI, ALP, D-dimer, FIB, and other clinical indicators in the diagnosis of prostate cancer bone metastasis. The clinical application value of mpMRI, ALP, D-dimer, FIB, and their combined indicators in diagnosing prostate cancer bone metastasis was assessed using receiver operating characteristic (ROC) curves. Results: The Kappa values comparing T1WI, T2WI fat suppression, DWI, and mpMRI with the results of prostate cancer bone metastasis were 0.536, 0.470, 0.629, and 0.691, respectively (P < 0.001). Compared to the non-bone metastasis group, the serum levels of ALP, D-dimer, and FIB in the bone metastasis group were significantly higher (P < 0.001). Multivariable logistic regression analysis indicated that mpMRI, ALP, D-dimer, and FIB are independent risk factors for prostate cancer bone metastasis (P < 0.05). The combined indicators showed the best performance, followed by the individual indicators of D-dimer, mpMRI, ALP, and FIB, all of which demonstrated good diagnostic value (P < 0.05). Conclusion: mpMRI, ALP, D-dimer, and FIB all demonstrate certain diagnostic efficacy for prostate cancer bone metastasis. The combined use of these indicators can further enhance diagnostic value, suggesting that they should be considered for broader application in clinical practice.展开更多
