Abstract
Methods for diagnosing prostate cancer (PCa) are developing in the direction of imaging. Advanced ultrasound examination modes include micro-Doppler, computerized-transrectal ultrasound, elastography, contrast-enhanced ultrasound and microultrasound. When two or more of these modes are used in PCa diagnosis, the combined technique is called multiparameter ultrasound (mp-US). Mp-US provides complementary information to multiparameter magnetic resonance imaging (mp-MRI) for diagnosing PCa. At present, no study has attempted to combine the characteristics of different ultrasound modes with advanced classification systems similar to the PIRADS system in mpMRI for the diagnosis of PCa. As an imaging method, mp-US has great potential in the diagnosis of PCa.

Neurobehavioral and Biochemical Evidences in Support of Protective Effect of Marrubiin (Furan Labdane Diterpene) from Marrubium vulgare Linn. and Its Extracts after Traumatic Brain Injury in Experimental Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4457973. [PMID: 35656476 PMCID: PMC9155918 DOI: 10.1155/2022/4457973] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/27/2022] [Accepted: 05/06/2022] [Indexed: 02/05/2023]
Abstract
Traumatic brain injuries due to sudden accidents cause major physical and mental health problems and are one of the main reasons behind the mortality and disability of patients. Research on alternate natural sources could be a boon for the rehabilitation of poor TBI patients. The literature indicates the Marrubium vulgare Linn. and its secondary metabolite marrubiin (furan labdane diterpene) possess various pharmacological properties such as vasorelaxant, calcium channel blocker, antioxidant, and antiedematogenic activities. Hence, in the present research, both marrubiin and hydroalcoholic extracts of the plant were evaluated for their neuroprotective effect after TBI. The neurological severity score and oxidative stress parameters are significantly altered by the test samples. Moreover, the neurotransmitter analysis indicated a significant change in GABA and glutamate. The histopathological study also supported the observed results. The improved neuroprotective potential of the extract could be attributed to the presence of a large number of secondary metabolites including marrubiin.

Abstract
Prostate biopsy is the definitive investigation to diagnose prostate cancer. The ideal procedure would be one that offers fast and efficient results safely as an outpatient procedure. Historically, transrectal ultrasound (TRUS) biopsy is considered the gold standard but transrectal biopsy can under-sample the anterior and apical regions of the prostate and is associated with a risk of prostate biopsy-related sepsis, which may require intensive care admission. Transperineal (TP) biopsy addresses the inefficient sampling of TRUS biopsy but historically has been done under general anaesthetic, which makes it difficult to incorporate into timed diagnostic pathways such as the National Health Service (NHS) 2-week cancer pathway. TRUS biopsy has remained the mainstay of clinical diagnosis because of its simplicity; however, the recent development of simpler local anaesthetic transperineal techniques has transformed outpatient biopsy practice. These techniques practically eliminate prostate biopsy-related sepsis, have a shallow learning curve and offer effective sampling of all areas of the prostate in an outpatient setting. The effectiveness of TP biopsy has been enhanced by the introduction of multiparametric MRI prior to biopsy, the use of PSA density for risk stratification in equivocal cases and combined with more efficient targeted and systematic biopsies techniques, such as the Ginsburg Protocol, has improved the tolerability and diagnostic yield of local anaesthetic TP biopsies, reducing the risk of complications from the oversampling associated with transperineal template mapping biopsies. Areas where the literature remains unclear is the optimum number of cores needed to detect clinically significant disease (CSD) in patients with a definable lesion on MRI, in particular, whether there is a need for systematic biopsy in the face of equivocal MRI findings to ensure no CSD is missed. The Covid-19 pandemic has had a profound impact on prostate cancer referrals and prostate biopsy techniques within the UK; prior to the pandemic 65% of all prostate biopsies were TRUS, since the pandemic the proportions have reversed such that now over 65% of all prostate biopsies in the NHS are transperineal.

A systematic review and meta-analysis of Histoscanning™ in prostate cancer diagnostics. World J Urol 2021; 39:3733-3740. [PMID: 33825986 DOI: 10.1007/s00345-021-03684-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 03/24/2021] [Indexed: 10/21/2022] Open
Abstract
CONTEXT The value of Histoscanning™ (HS) in prostate cancer (PCa) imaging is much debated, although it has been used in clinical practice for more than 10 years now. OBJECTIVE To summarize the data on HS from various PCa diagnostic perspectives to determine its potential. MATERIALS AND METHODS We performed a systematic search using 2 databases (Medline and Scopus) on the query "Histoscan*". The primary endpoint was HS accuracy. The secondary endpoints were: correlation of lesion volume by HS and histology, ability of HS to predict extracapsular extension or seminal vesicle invasion. RESULTS HS improved cancer detection rate "per core", OR = 16.37 (95% CI 13.2; 20.3), p < 0.0001, I2 = 98% and "per patient", OR = 1.83 (95% CI 1.51; 2.21), p < 0.0001, I2 = 95%. The pooled accuracy was markedly low: sensitivity - 0.2 (95% CI 0.19-0.21), specificity - 0.12 (0.11-0.13), AUC 0.12. 8 of 10 studiers showed no additional value for HS. The pooled accuracy with histology after RP was relatively better, yet still very low: sensitivity - 0.56 (95% CI 0.5-0.63), specificity - 0.23 (0.18-0.28), AUC 0.4. 9 of 12 studies did not show any benefit of HS. CONCLUSION This meta-analysis does not see the incremental value in comparing prostate Histoscanning with conventional TRUS in prostate cancer screening and targeted biopsy. HS proved to be slightly more accurate in predicting extracapsular extension on RP, but the available data does not allow us to draw any conclusions on its effectiveness in practice. Histoscanning is a modification of ultrasound for prostate cancer visualization. The available data suggest its low accuracy in screening and detecting of prostate cancer.

Abstract
The diagnosis of prostate cancer (PCa) can be challenging due to the limited performance of current diagnostic tests, including PSA, digital rectal examination and transrectal conventional US. Multiparametric MRI has improved PCa diagnosis and is recommended prior to biopsy; however, mp-MRI does miss a substantial number of PCa. Advanced US modalities include transrectal prostate elastography and contrast-enhanced US, as well as improved B-mode, micro-US and micro-Doppler techniques. These techniques can be combined to define a novel US approach, multiparametric US (mp-US). Mp-US improves PCa diagnosis but is not sufficiently accurate to obviate the utility of mp-MRI. Mp-US using advanced techniques and mp-MRI provide complementary information which will become even more important in the era of focal therapy, where precise identification of PCa location is needed.

Abstract
OBJECTIVE To perform a state of the art about indications and limits of ablative therapies for localized prostate cancer. METHODS A review of the scientific literature was performed in Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of keywords. Publications obtained were selected based on methodology, language and relevance. After selection, 107 articles were analysed. RESULTS The objective to combine reduction of side effects and oncological control has induced recent development of several ablative therapies. Beyond this heterogeneity, some preferential indications appear: unilateral cancer of low risk (but with significant volume, excluding active surveillance) or intermediate risk (excluding majority of grade 4); treatment targeted the index lesion, by quarter or hemi-ablation, based on biopsy and mpMRI. In addition, indications must considered specific limits of each energy, such as gland volume and tumor localization. CONCLUSION Based on new imaging and biopsy, ablative therapies will probably increased its role in the future in management of localize prostate cancer. The multiple ongoing trials will certainly be helpful to better define their indications and limits.

Abstract
BACKGROUND Prostate HistoScanning (PHS) is a tissue characterization system used to enhance prostate cancer (PCa) detection via transrectal ultrasound imaging. OBJECTIVE To assess the impact of supplementing systematic transrectal biopsy with up to three PHS true targeting (TT) guided biopsies on the PCa detection rate and preclinical patient assessment. DESIGN, SETTING, AND PARTICIPANTS This was a prospective study involving a cohort of 611 consecutive patients referred for transrectal prostate biopsy following suspicion of PCa. PHS-TT guided cores were obtained from up to three PHS lesions of ≥0.5cm3 per prostate and only one core per single PHS lesion. Histological outcomes from a systematic extended 12-core biopsy (Bx) scheme and additional PHS-TT guided cores were compared. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Comparison of PHS results and histopathology was performed per sextant. The χ2 and Mann-Whitney test were used to assess differences. Statistical significance was set at p<0.05. RESULTS AND LIMITATIONS PHS showed lesions of ≥0.5cm3 in 312 out of the 611 patients recruited. In this group, Bx detected PCa in 59% (185/312) and PHS-TT in 87% (270/312; p<0.001). The detection rate was 25% (944/3744 cores) for Bx and 68% (387/573 cores) for PHS-TT (p<0.001). Preclinical assessment was significantly better when using PHS-TT: Bx found 18.6% (58/312) and 8.3% (26/312), while PHS-TT found 42.3% (132/312) and 20.8% (65/312) of Gleason 7 and 8 cases, respectively (p<0.001). PHS-TT attributed Gleason score 6 to fewer patients (23.4%, 73/312) than Bx did (32.4%, 101/312; p=0.0021). CONCLUSIONS Patients with a suspicion of PCa may benefit from addition of a few PHS-TT cores to the standard Bx workflow. PATIENT SUMMARY Targeted biopsies of the prostate are proving to be equivalent to or better than standard systematic random sampling in many studies. Our study results support supplementing the standard schematic transrectal ultrasound-guided biopsy with a few guided cores harvested using the ultrasound-based prostate HistoScanning true targeting approach in cases for which multiparametric magnetic resonance imaging is not available.

Abstract
INTRODUCTION The local inflammatory process after prostate biopsies can have a negative impact on functional outcomes of radical prostatectomy. There is no evidence in literature demonstrating its impact on radical prostatectomy. OBJECTIVES To evaluate the impact of the number of TRUS core biopsies in the surgical morbidity and rate of positive margin on robot assisted radical prostatectomy (RARP). MATERIAL AND METHODS A prospectively maintained database of 2,054 RARPs in a single institution. Patients were further grouped into 2 groups based on the number of TRUS biopsy cores (G1≤12 cores; G2>12 cores). Multivariable logistic regression model was applied to analyze the impact of number of cores on complications. RESULTS A total number of 1,042 patients in the group 1 (≤12 cores) and 1,012 patients in the group 2 (>12 cores) were included. The rate of perioperative complications increased with higher number of biopsies (G1 6.4 vs. G2 8.5%; P=.03), but high grade complication (Clavien 3-4) were similar (G1 1.4 vs. G2 2.2%; P=.16). Positive surgical margin rates were similar in both groups (G1 11.8 vs. 9.98%; P=.2). At the multivariable logistic regression analysis shown that G2 had a 39% (OR 0.645) higher rate to experience perioperative complications during RARP. CONCLUSION Higher number of TRUS biopsy cores (>12) is associated to higher blood loss and perioperative complications during RARP. Careful preoperative evaluation for those patients underwent multiple biopsies or saturation protocols is mandatory. Application of longer intervals (>6 weeks) between biopsy and surgery may be advisable to minimize potential risks of surgical complications in patients may benefit from RARP. Further studies are still necessary to confirm these results.

Abstract
BACKGROUND The technique of prostate biopsy has evolved a long way since its inception to being a safe diagnostic procedure. The principles of the biopsy technique continue to improvise with the knowledge about prostate cancer and availability of newer treatment options like active surveillance and focal therapy. Currently, we depend on accurate cancer information from the biopsy more than ever for deciding the ideal treatment option. AIM The aim of this review is to present the major milestones in prostate biopsy technique evolutions and its impact on the prostate cancer management. ACQUISITION OF EVIDENCE We performed a detailed non-systematic literature review to present the historical facts on the transformations in prostate biopsy techniques and also the direction of present research to improve accurate cancer detection. SUMMARY OF EVIDENCE There is a clear change in trend in biopsy technique before and after the introduction of transrectal ultrasound and prostate specific antigen. In the earlier era, the biopsies were aimed at palpable nodules and obtaining adequate prostatic tissue for diagnosis while the later era has moved towards detection of non-palpable and early prostate cancer. Recently, there is an increasing trend towards image guided targeted biopsies to extract maximum cancer information from minimum biopsy cores. CONCLUSION Prostate biopsy techniques have seen major changes since its inception and have a major impact on prostate cancer management. There is a great potential for research which can further support the newer treatment options like focal therapy.

Abstract
PURPOSE To verify the reliability of HistoScanning™-based, true targeting (TT)-derived prostate biopsy. METHODS We relied on 40 patients suspicious for prostate cancer who underwent standard and TT-derived prostate biopsy. Sensitivity, specificity, positive predictive value, negative predictive value and the area under the curve (AUC) were assessed for the prediction of biopsy results per octant by HistoScanning™, using different HistoScanning™ signal volume cutoffs (>0, >0.2 and >0.5 ml). RESULTS Overall, 319 octants were analyzed. Of those, 64 (20.1 %) harbored prostate cancer. According to different HistoScanning™ signal volume cutoffs (>0, >0.2 and >0.5 ml), the AUCs for predicting biopsy results were: 0.51, 0.51 and 0.53, respectively. Similarly, the sensitivity, specificity, positive predictive and negative predictive values were: 20.7, 78.2, 17.4 and 81.6 %; 20.7, 82.0, 20.3 and 82.3 %; and 12.1, 94.6, 33.3 and 82.9 %, respectively. CONCLUSIONS Prediction of biopsy results based on HistoScanning™ signals and TT-derived biopsies was unreliable. Moreover, the AUC of TT-derived biopsies was low and did not improve when additional signal volume cutoffs were applied (>0.2 and >0.5 ml). We cannot recommend a variation of well-established biopsy standards or reduction in biopsy cores based on HistoScanning™ signals.
