Recent systematic reviews highlighted increasing use of cadaveric models in the surgical training, but reports on the characteristics of the models and their impact on training are lacking, as well as standardized recommendations on how to ensure the quality of surgical studies. The aim of our survey was to provide an easy guideline that would improve the quality of the studies involving cadavers for surgical training and research. After accurate literature review regarding surgical training on cadaveric models, a draft of the CACTUS guidelines involving 10 different items was drawn. Afterwards, the items were improved by questionnaire uploaded and spread to the experts in the field via Google form. The guideline was then reviewed following participants feedback, ergo, items that scored between 7 and 9 on nine-score Likert scale by 70% of respondents, and between 1 and 3 by fewer than 15% of respondents, were included in the proposed guideline, while items that scored between 1 and 3 by 70% of respondents, and between 7 and 9 by 15% or more of respondents were not. The process proceeded with Delphi rounds until the agreement for all items was unanimous. In total, 42 participants agreed to participate and 30 (71.4%) of them completed the Delphi survey. Unanimous agreement was almost always immediate concerning approval and ethical use of cadaver and providing brief outcome statement in terms of satisfaction in the use of the cadaver model through a short questionnaire. Other items were subjected to the minor adjustments. 'CACTUS' is a consensus-based guideline in the area of surgical training, simulation and anatomical studies and we believe that it will provide a useful guide to those writing manuscripts involving human cadavers.

Prostate cancer is the most common cancer in men. Diagnosis of prostate cancer poses a significant challenge, due to several different key parameters that need to be evaluated, such as age, history of prostate specific antigen (PSA), clinical exami...

Continuous increase of the cost of medical services around the world has become a major topic in the world today. Multiparametric prostate MRI has recently become a new standard in prostate cancer detection, especially in repeated biopsy settings. The method, although superior in cancer detection rates, is costly and requires additional training and equipment. The purpose of our study was to determine the costs and benefits that arise when introducing this method in prostate cancer diagnostics. Repeated prostate biopsy was performed in 101 consecutive patients in the period from 1 October 2016 to 1 July 2017. Patients were divided into two groups based on whether prostate mp-MRI was performed or not. The prices of specific procedures were obtained from the billing service of the Sestre milosrdnice University Hospital Center and patient models were created to determine financial costs and benefits. The cost of the entire diagnostic process per patient in the non-MRI group was HRK 1.931,05 and HRK 1.848,42 in the mpMRI group, or 4.28% less. Prostate mpMRI and subsequent mpMRI guided biopsies can reduce the overall cost in prostate cancer diagnostics despite the procedure itself being an additional cost. This is achieved by omitting prostate biopsies in patients with low malignancy risk.

The aim of this prospective clinical study was to determine the detection rate of prostate cancers by multiparametric magnetic resonance and transrectal ultrasound (mpMRI-TRUS) cognitive fusion biopsies in patients with a previously negative TRUS-guided biopsy. Between 1 October 2016 and 1 July 2017, in 101 consecutive patients with elevated antigen (PSA) and/or positive digital rectal examination and after a negative first TRUS biopsy, a second, repeated prostate biopsy was performed. In 24 patients, cognitive fusion mpMRI-TRUS biopsy of the prostate with 8-10 system cores and 1-3 target biopsies was performed, in line with the European Association of Urology guidelines. In 77 patients, only a classic, repeated TRUS guided biopsy was performed. In patients with mpMRI, the detection rate according to PIRADS-v2 reporting system was: PIRADS 1, n = 0; PIRADS 2, n = 0; PIRADS 3, n = 0; PIRADS 4, n = 6/8 (75%); and PIRADS 5, n = 2/3 (67%). In the group of patients with MR-TRUS cognitive fusion biopsy, the prostate cancer detection rate was 8/24 (33%), while in the control group the detection rate was 12/77 (16%), which was statistically significant (t test, p = 0.037, CI 95% is 0.01 to 0.37). Patients with PIRADS ≤ 3 (54%) could have avoided the biopsy.
