Key clinical point: Transgluteal CT-guided biopsy identified prostate cancer lesions in men without rectal access with no major complications reported.
Major finding: A total of 4 lesions were targeted using anatomic landmarks and 5 were targeted using contrast enhancement. All biopsies using transgluteal CT were technically successful and identified as prostate cancer. A total of 3 biopsies showed Gleason 6 cancer, and 6 biopsies showed clinically significant prostate cancers with Gleason 7 or above; a total of 7 patients underwent definitive treatment with surgery or radiation.
Study details: The data come from a retrospective study of 9 prostate cancer patients without rectal access who underwent transgluteal CT-guided biopsy between May 2016 and February 2021. The two targeting techniques were localizing with anatomic landmarks or localizing with contrast enhancement.
Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
