Abstract

Solitary fibrous tumor (SFT) is an uncommon neoplasm tipically located on the pleura (Chick et al., 2013 Mar). Althought prostatic cancer tend to be adenocarcinoma, prostatic solitary fibrous tumor might be a rare cause of prostatic growth. They usually are asymptomatic although they can produce lower urinary tract symptoms (LUTS). Diagnosis is anatomopathological although Magnetic Resonance (MRI) can be useful to evaluate local and metastatic involvement (Liu et al., 2019). An adequate treatment is the most important prognostic factor and it involves complete surgical resection. We report an 85-year-old male that had an enormous SFT with LUTS treated with surgery which was delayed because of COVID-19 pandemic.

Abstract

Background: A definition of the best strategy is necessary to optimize the follow-up of patients with previous negative transrectal guided ultrasound biopsy (TRUS-GB) and the persistence of raised prostate-specific antigen (PSA).The purpose of this study was to evaluate the prostate cancer (PCa) diagnostic rate of targeted transperineal ultrasound guided biopsy (TPUS-GB) with cognitive multiparametric magnetic resonance imaging (mpMRI) registration with concurrent systematic biopsy in patients with previous negative systematic TRUS-GB and persistently elevated PSA levels. Materials and methods: In this prospective study conducted at the University Infanta Sofia Hospital from April 2016 to November 2017, patients with one previous negative systematic TRUS-GB and persistently high PSA levels were referred for mpMRI prostate scans. All patients underwent systematic TPUS-GB and those patients with suspicious findings on mpMRI scans, Pirads 3 and 4-5, underwent a subsequent cognitive guidance mpMRI-TPUS-GB. Results: In total, 71 patients were included in this study. Suspicious findings on mpMRI scans prior to TPUS-GB were found in 50 patients (70.4%). 16 patients were diagnosed with prostate cancer (22.5%), of whom 14 (87.5%) had a mpMRI scan with Pirads 3 or Pirads 4-5. Patients with Pirads 3, 4 or 5 showed negative results in almost all cores taken by concurrent systematic TPUS-GB. Conclusions: Cognitive mpMRI-TPUS fusion biopsy is a useful tool to diagnose PCa in patients with previous negative prostate biopsy. The samples obtained from the suspicious areas in the mpMRI detect more cases of intermediate and high risk PCa compared to the samples obtained at random or from non-suspicious areas.

Abstract

Background: To evaluate the diagnostic efficacy in cancer prostate (PCa) of Multiparametric prostate magnetic resonance imaging (mp-MRI) targeted biopsy compared to standard systematic transrectal ultrasound-guided biopsy (TRUSGB) in biopsy-naïve patients. Methods: A total of 168 biopsy-naïve men with clinical suspicion of PCa due to elevated PSA levels and/or an abnormal digital rectal examination were consecutively enrolled from July 2011 to July 2014. All patients underwent TRUSGB. Patients with equivocal (Pi-rads 3) or suspicious lesion (Pi-rads 4-5), were additionally biopsied using two cores, by the same operator (cognitive technique). Results: Among the 168 cases, mp-MRI was equivocal for PCa (Pi-rads 3) in 46 subjects (27.4%) and suspicious (Pi-rads 4, 5) in 40 cases (23.8%). Of the 69 patients with PCa, standard TRUSGB showed Gleason ≥7 in 75% of patients with Pirads 3 and 77.8% in cases with Pirads 4-5 on mp-MRI. Among the 40 patients with Pi-rads 4-5 lesion on the MRI, cognitive mp-MRI-guided biopsy (MRCGB) detected a higher number of cases of PCa with a Gleason score equal or superior to 7 (90%) with a higher negative predictive value (97.5%) than cases with Pi-rads 3 lesion or subjects with TRUSGB alone. Conclusions: mp-MRI followed by selective biopsy seems to be a valuable tool to improve the diagnosis of intermediate and high risk PCa compared to standard TRUSGB.
