Medical Dosimetry | Year: 2014
Radiotherapy for epithelioid hemangioendothelioma (EHE) using volumetric intensity-modulated arc radiotherapy (VMAT). A 48-year-old woman was referred for curative irradiation of a vertebral EHE after failure of surgery. A comparison between VMAT and conventional conformal tridimensional (3D) dosimetry was performed and potential advantage of VMAT for sparing critical organs from irradiation[U+05F3]s side effects was discussed. The total delivered dose on the planning target volume was 54Gy in 27 fractions. The patient was finally treated with VMAT. The tolerance was excellent. There was no acute toxicity, including no increase in pain. With a follow-up of 18 months, no delayed toxicity was reported. The clinical response consisted of a decrease in the dorsal pain. The Dmax for the spinal cord was reduced from 55Gy (3D-radiotherapy [RT]) (which would be an unacceptable dose to the spine because of the risk of myelopathy) to 42.8Gy (VMAT), which remains below the recommended dose threshold (45Gy). The dose delivered to 20% of organ volume (D20) was reduced from 47Gy (3D-RT) to 3Gy (VMAT) for the spinal cord. The study shows that VMAT allows the delivery of curative treatment for vertebral EHEs because of critical organ sparing. © 2014 American Association of Medical Dosimetrists.

The incidence of brain metastases (BM) has increased due to the improvement of therapeutics and diagnostic imaging, but also to an aging population. The initial symptoms may develop suddenly or insidiously over weeks or months. The symptoms depend on the location of the BM and related complications (hydrocephalus, tumor hemorrhage, cerebral herniation). Headaches are the most frequent symptoms (50%); they are related to intracranial hypertension. Cognitive deficits are commonly described at diagnosis (67 to 90.5%). Cognitive assessment is essential because of its impact on patients' prognosis and quality of life. Nevertheless, these deficits remain underestimated. The Karnofsky Perfomance Scale and the Mini Mental State Examination (MMSE) seem inadequate. A short battery was proposed and internationally validated, assessing seven domains: attention (Digit Symbol Test WAIS-III), episodic memory (Hopkins Verbal Learning Test [HVLT]), working memory (Digit Span Test WAIS-III), verbal fluency (Controlled Oral Word Association Test [COWA]), fine motor dexterity (Grooved Pegboard Test), information processing speed (Trail Making Test [TMT] A) and executive functions (TMT B). This battery is relevant, feasible and associated with a good compliance. These cognitive tests are currently recommended to assess cognitive functions in patients with BM. © John Libbey Eurotext.

Background: Risk prediction models for prostate cancer (PCa) have become important tools in reducing unnecessary prostate biopsies. The Prostate Health Index (PHI) may increase the predictive accuracy of such models. Objectives: To compare two PCa risk calculators (RCs) that include PHI. Design, setting, and participants: We evaluated the predictive performance of a previously developed PHI-based nomogram and updated versions of the European Randomized Study of Screening for Prostate Cancer (ERSPC) RCs based on digital rectal examination (DRE): RC3 (no prior biopsy) and RC4 (prior biopsy). For the ERSPC updates, the original RCs were recalibrated and PHI was added as a predictor. The PHI-updated ERSPC RCs were compared with the Lughezzani nomogram in 1185 men from four European sites. Outcomes were biopsy-detectable PC and potentially advanced or aggressive PCa, defined as clinical stage >T2b and/or a Gleason score ≥7 (clinically relevant PCa). Results and limitations: The PHI-updated ERSPC models had a combined area under the curve for the receiver operating characteristic (AUC) of 0.72 for all PCa and 0.68 for clinically relevant PCa. For the Lughezzani PHI-based nomogram, AUCs were 0.75 for all PCa and 0.69 for clinically relevant PCa. For men without a prior biopsy, PHI-updated RC3 resulted in AUCs of 0.73 for PCa and 0.66 for clinically relevant PCa. Decision curves confirmed these patterns, although the number of clinically relevant cancers was low. Conclusion: Differences between RCs that include PHI are small. Addition of PHI to an RC leads to further reductions in the rate of unnecessary biopsies when compared to a strategy based on prostate-specific antigen measurement. Patient summary: Risk prediction models for prostate cancer have become important tools in reducing unnecessary prostate biopsies. We compared two risk prediction models for prostate cancer that include the Prostate Health Index. We found that these models are equivalent to each other, and both perform better than the prostate-specific antigen test alone in predicting cancer. Prostate-specific antigen screening reduces prostate cancer mortality but leads to many unnecessary prostate biopsies and overdiagnosis. Inclusion of the Prostate Health Index results in an equivalent increase in predictive ability for both the Lughezzani and the updated European Randomized Study of Screening for Prostate Cancer models. © 2015 European Association of Urology.

The authors, through various testimonials from writers who almost died during the wars of the twentieth century, show how the psychological trauma and its effects on memory can be elaborated mainly by the work of writing. Writing is perceived as a weaving of the spatio-temporal fracture directly caused by the psychological trauma. © 2015 Elsevier Masson SAS.

Objectives To prospectively test the diagnostic accuracy of the percentage of prostate specific antigen (PSA) isoform [-2]proPSA (%p2PSA) and the Prostate Health Index (PHI), and to determine their role for discrimination between significant and insignificant prostate cancer at initial and repeat prostate biopsy in men aged ≤65 years. Patients and Methods The diagnostic performance of %p2PSA and PHI were evaluated in a multicentre study. In all, 769 men aged ≤65 years scheduled for initial or repeat prostate biopsy were recruited in four sites based on a total PSA (t-PSA) level of 1.6-8.0 ng/mL World Health Organization (WHO) calibrated (2-10 ng/mL Hybritech-calibrated). Serum samples were measured for the concentration of t-PSA, free PSA (f-PSA) and p2PSA with Beckman Coulter immunoassays on Access-2 or DxI800 instruments. PHI was calculated as (p2PSA/f-PSA × √t-PSA). Uni- and multivariable logistic regression models and an artificial neural network (ANN) were complemented by decision curve analysis (DCA). Results In univariate analysis %p2PSA and PHI were the best predictors of prostate cancer detection in all patients (area under the curve [AUC] 0.72 and 0.73, respectively), at initial (AUC 0.67 and 0.69) and repeat biopsy (AUC 0.74 and 0.74). t-PSA and %f-PSA performed less accurately for all patients (AUC 0.54 and 0.62). For detection of significant prostate cancer (based on Prostate Cancer Research International Active Surveillance [PRIAS] criteria) the %p2PSA and PHI equally demonstrated best performance (AUC 0.70 and 0.73) compared with t-PSA and %f-PSA (AUC 0.54 and 0.59). In multivariate analysis PHI we added to a base model of age, prostate volume, digital rectal examination, t-PSA and %f-PSA. PHI was strongest in predicting prostate cancer in all patients, at initial and repeat biopsy and for significant prostate cancer (AUC 0.73, 0.68, 0.78 and 0.72, respectively). In DCA for all patients the ANN showed the broadest threshold probability and best net benefit. PHI as single parameter and the base model + PHI were equivalent with threshold probability and net benefit nearing those of the ANN. For significant cancers the ANN was the strongest parameter in DCA. Conclusion The present multicentre study showed that %p2PSA and PHI have a superior diagnostic performance for detecting prostate cancer in the PSA range of 1.6-8.0 ng/mL compared with t-PSA and %f-PSA at initial and repeat biopsy and for predicting significant prostate cancer in men aged ≤65 years. They are equally superior for counselling patients before biopsy. © 2015 BJU International.
