CEUS Targeted Biopsies Compared to mpMRI Targeted and Systematic Biopsies for the Detection of Prostate Cancer

2016-07-14 00:38:22 | BioPortfolio

Summary

The current standard for Prostate Cancer (PCa) detection remains taking 10-12 systematic biopsies of the prostate. This approach leads to overdiagnosis of insignificant PCa on the one hand and underdiagnosis and undergrading of significant PCa on the other. multiparametric Magnetic Resonance Imaging (mpMRI) has seen an increasing uptake in the clinics for biopsy targeting, but the value in biopsy naive patients remains controversial. With Contrast Enhanced UltraSound (CEUS) cancer induced neovascularisation can be visualised with the potential to improve ultrasound imaging for prostate cancer detection and localisation significantly. The past years numerous studies have been performed with CEUS, all basing their results on subjective judgement of the investigator. To overcome these difficulties CEUS quantification techniques have been used with encouraging first results. These imaging techniques have been proposed to improve the yield of prostate biopsies and possibly replacing systematic biopsies.

In this trial mpMRI imaging and CEUS + quantification are performed before primary biopsy. Using a fusion device, targeted biopsies are taken from predefined MRI lesions and CEUS lesions, together with standard systematic biopsies in the same patients by separate blinded clinicians. The main outcome measure is the per-patient (significant) prostate cancer detection rate for each of the biopsy regimens.

Medical and Biotech [MESH] Definitions

Radiotherapy where cytotoxic radionuclides are linked to antibodies in order to deliver toxins directly to tumor targets. Therapy with targeted radiation rather than antibody-targeted toxins (IMMUNOTOXINS) has the advantage that adjacent tumor cells, which lack the appropriate antigenic determinants, can be destroyed by radiation cross-fire. Radioimmunotherapy is sometimes called targeted radiotherapy, but this latter term can also refer to radionuclides linked to non-immune molecules (see RADIOTHERAPY).

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.

Clinically atypical nevi (usually exceeding 5 mm in diameter and having variable pigmentation and ill defined borders) with an increased risk for development of non-familial cutaneous malignant melanoma. Biopsies show melanocytic dysplasia. Nevi are clinically and histologically identical to the precursor lesions for melanoma in the B-K mole syndrome. (Stedman, 25th ed)

A mitochondrial encephalomyopathy characterized clinically by a mixed seizure disorder, myoclonus, progressive ataxia, spasticity, and a mild myopathy. Dysarthria, optic atrophy, growth retardation, deafness, and dementia may also occur. This condition tends to present in childhood and to be transmitted via maternal lineage. Muscle biopsies reveal ragged-red fibers and respiratory chain enzymatic defects. (From Adams et al., Principles of Neurology, 6th ed, p986)
