Intraindividual comparison between 68Ga-PSMA-PET/CT and mpMRI for intraprostatic tumor delineation in patients with primary prostate cancer: a retrospective analysis in 101 patients

Purpose Accurate delineation of intraprostatic gross tumor volume (GTV) is mandatory for successful fusion biopsy guidance and focal therapy planning of prostate cancer (PCa). Multiparametric magnetic resonance imaging (mpMRI) is the current gold standard for GTV delineation; however, prostate-speci...

description Purpose Accurate delineation of intraprostatic gross tumor volume (GTV) is mandatory for successful fusion biopsy guidance and focal therapy planning of prostate cancer (PCa). Multiparametric magnetic resonance imaging (mpMRI) is the current gold standard for GTV delineation; however, prostate-specific membrane antigen positron emission tomography (PSMA-PET) is emerging as a promising alternative. This study compares GTV delineation between mpMRI and 68 Ga-PSMA-PET in a large number of patients using validated contouring approaches. Methods One hundred one patients with biopsy-proven primary PCa who underwent mpMRI and 68 Ga-PSMA-PET within 3 months before primary treatment were retrospectively enrolled. Clinical parameters (age, PSA, Gleason score in biopsy) were documented. GTV based on MRI and PET images were delineated; volumes measured and laterality determined. Additionally, biopsy data from 77 patients was analyzed. Univariate and multivariate binary logistic regression analyses were performed using concordance in laterality as the endpoint. Results In total mpMRI and 68 Ga-PSMA-PET detected 151 and 159 lesions, respectively. Median GTV-MRI (2.8 ml, 95% CI 2.31–3.38 ml) was significantly ( p

Median GTV-MRI (2.8 ml, 95% CI 2.31–3.38 ml) was significantly ( p  &lt; 0.0001) smaller than median GTV-PET (4.9 ml, 95% CI 3.9–6.6 ml). 68 Ga-PSMA-PET detected significantly more bilateral lesions than mpMRI (71 vs 57, p  = 0.03). Analysis of patients with bilateral lesions in biopsy showed a significant higher concordance of laterality in 68 Ga-PSMA-PET ( p  = 0.03). In univariate analysis, PSA level and volume of GTV-MRI had an impact on concordance in laterality ( p  = 0.02 and p  = 0.01), whereas in multivariate analysis, only GTV-MRI volume remained significant ( p  = 0.04). Conclusion MpMRI and 68 Ga-PSMA-PET detect a similar amount of PCa lesions. However, GTV-PET had approximately twice the volume (median 4.9 ml vs 2.8 ml) and detected significantly more bilateral lesions than mpMRI. Thus, 68 Ga-PSMA-PET gives highly important complementary information. Since we could not find any strong evidence for parameters to guide when 68 Ga-PSMA-PET is dispensable, it should be performed additionally to MRI in patients with intermediate and high-risk PCa according to D’Amico classification to improve GTV delineation.</description><identifier>ISSN: 1619-7070</identifier><identifier>EISSN: 1619-7089</identifier><identifier>DOI: 10.1007/s00259-020-04827-6</identifier><identifier>PMID: 32342192</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Antigens ; Biopsy ; Cardiology ; Computed tomography ; Contouring ; Delineation ; Emission analysis ; Imaging ; Lesions ; Magnetic resonance imaging ; Medicine ; Medicine &amp; Public Health ; Multivariate analysis ; Nuclear Medicine ; Oncology ; Oncology – Genitourinary ; Original ; Original Article ; Orthopedics ; Parameters ; Patients ; Positron emission ; Positron emission tomography ; Prostate cancer ; Radiology ; Tomography ; Tumors</subject><ispartof>European journal of nuclear medicine and molecular imaging, 2020-11, Vol.47 (12), p.2796-2803</ispartof><rights>The Author(s) 2020</rights><rights>The Author(s) 2020.
