Background: Hormone therapy is a front-line therapy for men with prostate cancer and is associated with adverse cardiovascular events. The utility of vascular calcification for cardiovascular risk stratification in men with prostate cancer is unknown. Methods: 211 consecutive patients who underwent 18F-fluciclovine positron emission tomography (PET)/computed tomography (CT) at a single institution for recurrent prostate cancer were retrospectively identified. Clinical and demographic data were obtained from the medical record. Coronary and aortic calcification were qualitatively assessed on non-gated CT scans using standardized scoring systems. The primary outcome was a composite of subsequent major adverse cardiovascular event (MACE; myocardial infarction, stroke, coronary or peripheral revascularization, heart failure hospitalization) or all-cause mortality. Results: Median age was 69 (IQR 64, 75) years and cardiovascular comorbidities were common (70% hypertension, 65% hyperlipidemia, 47% current or former smoking, 20% diabetes mellitus). Over a median of 16.5 months, 8 patients (4%) met the primary outcome. Patients with MACE or death were older and had higher prevalence of traditional cardiovascular comorbidities (risk ratio [RR] 1.3 for hypertension, 1.4 for hyperlipidemia, 1.3 for diabetes mellitus; p>0.05 for all). Coronary and aortic calcification were more common in patients with MACE or death. Severe coronary calcification (RR=6.1, 95% CI 1.6-23.2, p=0.008) and severe thoracic aortic calcification (RR=9.9, 95% CI 2.0-47.6, p=0.004) were associated with significantly increased risk of MACE or death. Conclusions: Coronary and aortic calcification on PET/CT imaging are associated with significantly increased risk of MACE or death in men with recurrent prostate cancer. Vascular calcification may have utility for cardiovascular risk stratification in men receiving hormone therapy for prostate cancer.

Background: Men who receive androgen deprivation therapy for prostate cancer may be at increased risk for cardiovascular events. Vascular calcification is predictive of coronary events in the general population. The prevalence of vascular calcification in men with prostate cancer is not known. Methods: 211 consecutive patients who underwent 18F-fluciclovine positron emission tomography (PET) /computed tomography (CT) at Washington University School of Medicine for recurrent prostate cancer were retrospectively identified. Clinical, demographic, and cardiac biomarker data were obtained from the medical record. Coronary and aortic calcification were qualitatively assessed on non-gated CT scans using standardized scoring systems. Results: Among 211 men with recurrent prostate cancer, median age was 69 (IQR 64, 75) years. Cardiovascular comorbidities were common (70% hypertension, 65% hyperlipidemia, 20% diabetes mellitus, 47% current or former smoking). 21% carried a clinical diagnosis of coronary artery disease while 6% had peripheral vascular disease. On CT imaging, 147 patients (70%) had coronary artery calcification of whom 29 (20%) had severe calcification. Additionally, 189 patients (90%) had aortic calcification on CT imaging of whom 48 (25%) had severe thoracic aortic calcification and 109 (58%) had severe calcification at the aortoiliac bifurcation. Conclusions: Coronary and peripheral vascular calcification are common on PET/CT imaging in men with prostate cancer. Vascular calcification on CT imaging may have utility for cardiovascular risk stratification and guiding implementation of cardiovascular therapies in men receiving androgen deprivation therapy.

Abstract Introduction Type-2 diabetes mellitus (T2DM) is associated with early and severe atherosclerosis. However, few biomarkers can predict cardiovascular events in this population. Methods We followed 964 patients with coronary artery disease (CAD), assessing at baseline galectin-3, monocyte chemoattractant protein-1 (MCP-1) and N-terminal fragment of brain natriuretic peptide (NT-proBNP) plasma levels. Secondary outcomes were acute ischemia and heart failure or death. Primary outcome was the combination of the secondary outcomes. Results Male patients were 75.0% in T2DM and 76.6% in the non-T2DM subgroup (p=0.609). Age was 61.0 (54–72) and 60.0 (51–71) years, respectively (p=0.092). 232 patients had T2DM. Patients with T2DM showed higher MCP-1 [144 (113–195) vs. 133 (105–173) pg/ml, p=0.006] and galectin-3 [8.3 (6.5–10.5) vs. 7.8 (5.9–9.8) ng/ml, p=0.049] levels. Median follow-up was 5.39 years (2.81- 6.92). Galectin-3 levels were associated with increased risk of the primary outcome in T2DM patients [HR 1.57 (1.07–2.30); p=0.022], along with a history of cerebrovascular events. Treatment with clopidogrel was associated with lower risk. In contrast, NT-proBNP and MCP-1, but not galectin-3, were related to increased risk of the event in non-diabetic patients [HR 1.21 (1.04–1.42); p=0.017 and HR 1.23 (1.05–1.44); p=0.012, respectively], along with male sex and age. Galectin-3 was also the only biomarker that predicted the development of acute ischemic events and heart failure or death in T2DM patients, while in non-diabetics MCP-1 and NT-proBNP, respectively, predicted these events. Conclusion In CAD patients, cardiovascular events are predicted by galectin-3 plasma levels in patients with T2DM, and by MCP-1 and NT-proBNP in those without T2DM.

Abstract Objective To investigate the impact of digital PET/CT on diagnostic certainty, patient-based sensitivity and interrater reliability. Methods Four physicians retrospectively evaluated two matched cohorts of patients undergoing [68Ga]Ga-PSMA-11 PET/CT on a digital (dPET/CT n = 65) or an analogue scanner (aPET/CT n = 65) for recurrent prostate cancer between 11/2018 and 03/2019. The number of equivocal and pathological lesions as well as the frequency of discrepant findings and the interrater reliability for the two scanners were compared. Results dPET/CT detected more lesions than aPET/CT (p < 0.001). A higher number of pathological scans were observed for dPET/CT (83% vs. 57%, p < 0.001). The true-positive rate at follow-up was 100% for dPET/CT compared to 84% for aPET/CT (p < 0.001). The proportion of lesions rated as non-pathological as a total of all PSMA-avid lesions detected for dPET/CT was comparable to aPET/CT (61.8% vs. 57.0%, p = 0.99). Neither a higher rate of diagnostically uncertain lesions (11.5% dPET/CT vs. 13.7% aPET/CT, p = 0.95) nor discrepant scans (where one or more readers differed in opinion as to whether the scan is pathological) were observed (18% dPET/CT vs. 17% aPET/CT, p = 0.76). Interrater reliability for pathological lesions was excellent for both scanner types (Cronbach’s α = 0.923 dPET/CT; α = 0.948 aPET/CT) and interrater agreement was substantial for dPET/CT (Krippendorf’s α = 0.701) and almost perfect in aPET/CT (α = 0.802). Conclusions A higher detection rate for pathological lesions for dPET/CT compared with aPET/CT in multiple readers was observed. This improved sensitivity was coupled with an improved true-positive rate and was not associated with increased diagnostic uncertainty, rate of non-specific lesions, or reduced interrater reliability. Key Points • New generation digital scanners detect more cancer lesions in men with prostate cancer. • When using digital scanners, the doctors are able to diagnose prostate cancer lesions with better certainty • When using digital scanners, the doctors do not disagree with each other more than with other scanner types.
