Prevention of thromboembolic events after radical prostatectomy in patients with hereditary thrombophilia due to a factor V Leiden mutation by multidisciplinary coagulation management.

Objective: To examine the perioperative impact of factor V Leiden mutation on thromboembolic events' risk in radical prostatectomy (RP) patients. With an incidence of about 5%, factor V Leiden mutation is the most common hereditary hypercoagulability among Caucasians and rarer in Asia. The increased risk of thromboembolic events is three- to seven-fold in heterozygous and to 80-fold in homozygous patients. Methods: Within our prospectively collected database, we analysed 33 006 prostate cancer patients treated with RP between December 2001 and December 2020. Of those, patients with factor V Leiden mutation were identified. All patients received individualised recommendation of haemostaseologists for perioperative anticoagulation. Thromboembolic complications (deep vein thrombosis and pulmonary embolism) were assessed during hospital stay, as well as according to patient reported outcomes within the first 3 months after RP. Results: Overall, 85 (0.3%) patients with known factor V Leiden mutation were identified. Median age was 65 (interquartile range: 61-68) years. There was at least one thrombosis in 53 (62.4%) patients and 31 (36.5%) patients had at least one embolic event in their medical history before RP. Within all 85 patients with factor V Leiden mutation, we experienced no thromboembolic complications within the first 3 months after surgery. Conclusion: In our cohort of patients with factor V Leiden mutation, no thromboembolic events were observed after RP with an individualised perioperative coagulation management concept. This may reassure patients with this hereditary condition who are counselled for RP.

Increasing the attractiveness of surgical disciplines for students: Implications of a robot-assisted hands-on training course for medical education.

Background: Structured implementation of robot-assisted surgery in the field of medical education is lacking. We assessed students' interest in robot-assisted surgery and tested if the implementation of a hands-on robotic course into the curriculum could increase the interest to join a surgical discipline in general and especially in female students, since women are clearly underrepresented in surgical disciplines. Methods: After a prostate cancer focused seminar, 100 students were 1:1 randomized into two groups. Group B: Baseline characteristics and professional interest were assessed prior and after a hands-on robotic course, using a da Vinci® console with simulator (da Vinci® Surgical training, Intuitive Surgical Inc., USA). Group A served as post-interventional consistency control group, received the questionnaire only once after the hands-on training. Results: The male to female ratio of students was 54% and 46%. The interest to turn into urology/surgery, categorized as yes", "no", "maybe" changed from 18 to 16%, 36 to 30% and 46 to 54% respectively after the hands-on robotic course (p < 0.001). Also, the positive attitude towards the surgical field significantly increased (20 vs. 48%; p < 0.001). Comparing male and female students, virtually identical proportions (23 vs. 23%) opted for joining urology or surgery as a discipline, whereas rejection (45 vs. 25%) and perchance (32 vs. 50%) of that notion differed between genders (p = 0.12). Conclusion: Our results demonstrate great demand for implementing robotic training into medical education for an up-to-date curriculum. Although the decision process on career choice is widely multifactorial, stereotypes associated with surgical disciplines should be eliminated. This could have a particularly positive effect on the recruitment of female medical students since women are clearly underrepresented in surgical disciplines although currently and with increasing proportions, more female students are enrolled in medical schools then male.

Pan-segmental intraprostatic lesions involving mid-gland and apex of prostate (mid-apical lesions): assessing the true value of extreme apical biopsy cores.

OBJECTIVE: When considering increased morbidity of apical biopsies, the added diagnostic value of separate targeting of mid-gland and apical segment of the pan-segmental mid-apical mpMRI prostate cancer (PCa) suspicious lesions was assessed. MATERIALS AND METHODS: A total of 420 patients with a single mpMRI PCa-suspicious PI-RADS ≥ 3 intraprostatic lesion extending from the mid-gland to the apical segment of the gland underwent transrectal MRI-targeted (TBx) and systematic prostate biopsy. Clinically significant PCa (CsPCa) was defined as Gleason Score (GS) ≥ 3 + 4. PCa detection rates of TBx cores were assessed according to targeted anatomical segments. Finally, the diagnostic values of two theoretical TBx protocols utilizing 1-core (A) vs. 2-cores (B) per anatomical segment were compared. RESULTS: TBx within the pan-segmental mid-apical lesions yielded 44% of csPCa. After stratification into mid- vs. apical segment of the lesion, csPCa was detected in 36% (mid-gland) and 32% (apex), respectively. Within the patients who had no csPCa detection by mid-gland sampling (64%, n = 270), extreme apical TBx yielded additional 8.1% of csPCa. Comparison of extreme apical TBx strategy B vs. overall PCa detection in our cohort revealed corresponding similar rates of 49 vs.50% and 31 vs.32%, respectively. CONCLUSION: Separate analyses of both segments, mid-gland and apex, clearly revealed the diagnostic contribution of apical TBx. Our findings strongly suggest to perform extreme apical TBx even within pan-segmental lesions. Moreover, our results indicate that a higher number of cores sampled from the mid-gland segment might be avoided if complemented with a two-core extreme apical TBx.
