Advanced strain elastography is a reliable approach for prostate cancer detection in patients with elevated PSA levels. Sci Rep 2024; 14:2917. [PMID: 38316992 PMCID: PMC10844258 DOI: 10.1038/s41598-024-53440-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 01/31/2024] [Indexed: 02/07/2024] Open
Abstract
This study aimed to examine the validity and reproducibility of strain elastography (SE) for detecting prostate cancer (PCa) in patients with elevated prostate-specific antigen (PSA) levels. The study included 107 patients with elevated PSA levels. All eligible patients underwent transrectal ultrasound (TRUS) with real-time elastography (RTE) to detect suspicious lesions. Two readers independently evaluated the lesions and assigned a strain ratio and elastography score to each lesion. Histopathology was used as a reference standard to estimate the validity of RTE in predicting malignant lesions. An intraclass correlation (ICC) was performed to detect reliability of the strain ratios and elastography scores. TRUS-guided biopsy detected malignancies in 64 (59.8%) patients. TRUS with RTE revealed 122 lesions. The strain ratio index (SRI) cut-off values to diagnose malignancy were 4.05 and 4.35, with sensitivity, specificity, and accuracy of 94.7%, 91.3%, and 93.4%, respectively. An elastography score > 3 was the best cut-off value for detecting malignancy. According to readers, the sensitivity, specificity, and accuracy were 91.3-94.7%, 89.5-93.4%, and 91.3-90.9%, respectively. Excellent inter-reader agreement was recorded for SRI and elastography scores, with ICC of 0.937 and 0.800, respectively. SE proves to be an efficient tool for detecting PCa with high accuracy in patients with elevated PSA levels.

A Novel Modality Enables New Evidence-Based Individual Risk Stratification That Can Potentially Lead to Decisive Management and Treatment Decisions in Prostate Cancer. Diagnostics (Basel) 2023; 13:diagnostics13030424. [PMID: 36766529 PMCID: PMC9914539 DOI: 10.3390/diagnostics13030424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 01/16/2023] [Accepted: 01/21/2023] [Indexed: 01/26/2023] Open
Abstract
A key step in providing management/treatment options to men with suspected prostate cancer (PCa) is categorizing the risk in terms of the presence of benign, low-risk, intermediate-risk, or high-risk disease. Our novel modality brings new evidence, based on the long-known hallmark characteristic of PCa-decreased zinc (Zn), which is the most direct metabolic sign of malignancy and its aggressiveness. To date, this approach has not been adopted for clinical use for a number of reasons that are described in this article, and which have been addressed by our approach. Zn has to be measured on fresh samples, prior to fixating in formalin; therefore, samples have to be scanned during the biopsy session. As Zn depletion occurs in the glands where the tumors develop, estimation of the glands' levels in the scanned tissue, along with their compactness, are essential for accurate diagnosis. Combined with the Zn depletion, this facilitates a reliable assessment of disease aggressiveness. Data gathered in the clinical study described here indicate that, in addition to improving the biopsy quality by real-time interactive guidance, a malignancy score can now be established for the entire prostate, allowing higher granularity personalized risk stratification and more decisive treatment decisions for all PCa patients.

Clinically significant prostate cancer (csPCa) detection with various prostate sampling schemes based on different csPCa definitions. BMC Urol 2021; 21:183. [PMID: 34949183 PMCID: PMC8697444 DOI: 10.1186/s12894-021-00949-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 12/16/2021] [Indexed: 11/20/2022] Open
Abstract
Background Combining targeted biopsy (TB) with systematic biopsy (SB) is currently recommended as the first-line biopsy method by the European Association of Urology (EAU) guidelines in patients diagnosed with prostate cancer (PCa) with an abnormal magnetic resonance imaging (MRI). The combined SB and TB indeed detected an additional number of patients with clinically significant prostate cancer (csPCa); however, it did so at the expense of a concomitant increase in biopsy cores. Our study aimed to evaluate if ipsilateral SB (ipsi-SB) + TB or contralateral SB (contra-SB) + TB could achieve almost equal csPCa detection rates as SB + TB using fewer cores based on a different csPCa definition. Methods Patients with at least one positive prostate lesion were prospectively diagnosed by MRI. The combination of TB and SB was conducted in all patients. We compared the csPCa detection rates of the following four hypothetical biopsy sampling schemes with those of SB + TB: SB, TB, ipsi-SB + TB, and contra-SB + TB. Results The study enrolled 279 men. The median core of SB, TB, ipsi-SB + TB, and contra-SB + TB was 10, 2, 7 and 7, respectively (P < 0.001). ipsi-SB + TB detected significantly more patients with csPCa than contra-SB + TB based on the EAU guidelines (P = 0.042). They were almost equal on the basis of the Epstein criteria (P = 1.000). Compared with SB + TB, each remaining method detected significantly fewer patients with csPCa regardless of the definition (P < 0.001) except ipsi-SB + TB on the grounds of D1 (P = 0.066). Ten additional subjects were identified with a higher Gleason score (GS) on contra-SB + TB, and only one was considered as significantly upgraded (GS = 6 on ipsi-SB + TB to a GS of 8 on contra-SB + TB). Conclusions Ipsi-SB + TB could acquire an almost equivalent csPCa detection value to SB + TB using significantly fewer cores when csPCa was defined according to the EAU guidelines. Given that there was only one significantly upgrading patient on contra-SB, our results suggested that contra-SB could be avoided.

[PMID: 31754091 PMCID: PMC6883763 DOI: 10.12659/msm.917344] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Accepted: 08/21/2019] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND The present study aimed to assess the correlation between prostate volume and prostate cancer (PCa) detection by strain elastography (SE)-guided targeted biopsy (TB) compared with conventional transrectal ultrasound (TRUS)-guided systematic biopsy (SB). MATERIAL AND METHODS This retrospective study enrolled 357 patients suspected to have PCa. All patients received TRUS-guided 10-core SB and SE-guided TB. The sensitivity for PCa detected by SE-guided TB was compared with that by TRUS-guided SB, in combination with prostate biopsy pathology. The correlation between the prostate volume and the detection rate of SE-guided TB was investigated. RESULTS PCa was pathologically confirmed in 151 out of 357 patients. The by-patient detection rate of TRUS-guided SB was 72.8% (110/151). Subsequently, a further increase of 6.6% (10/151) in PCa determination was obtained by the SE-guided TB. The sensitivity of SE-guided TB for patients with prostate volume <30 ml, 30-50 ml, 51-80 ml, and >80 ml was 91.7% (44/48), 80.3% (53/66), 70.4% (19/27), and 40.0% (4/10), respectively (p=0.002). For patients with a prostate volume less than 30 ml, SE-guided TB (91.7%) had a higher sensitivity than SB (62.5%) (p<0.007). CONCLUSIONS SE-guided TB has a higher detection rate of PCa in comparison with TRUS-guided SB. There was also a negative correlation between prostate volume and SE-guided TB. Therefore, use of SE-guided TB may complement use of conventional SB, especially for patients with smaller prostate volume.
