Prostate interventions in patients with mild haemophilia: Safe and feasible.

INTRODUCTION: To date, there is no specific recommendation or evaluation of the morbidity of prostate surgery in patients with haemophilia (PWH) although this surgery is common and at high risk of bleeding. AIM: To assess the post-operative morbidity of benign prostate hyperplasia (BPH) surgeries and of oncological prostate interventions in patients with mild haemophilia A or B. METHODS: We performed a monocentre, epidemiological, in real life study. Data were collected between 1 January, 1997 and 1 September, 2020 and focused on prostate biopsy, radical prostatectomy, prostate radiotherapy, simple prostatectomy, transurethral resection of prostate (TURP) and laser-vaporisation in patients with mild haemophilia A or B. RESULTS: Between 1 January, 1997 and 1 September, 2020, 51 interventions were performed on 30 patients with mild haemophilia. Haemophilia A represented 93.33% of the population and haemophilia B 6.67%. For prostate biopsies (n = 24), median length of hospitalisation was 4 days and only one patient needed a blood transfusion. No patient needed re-admission. For prostatectomy (n = 10), one patient presented with intra-operative and post-operative bleeding. Two patients required re-admission. The other patients did not present any significant haemorrhagic symptoms. For radiotherapy (n = 4), two patients presented a grade II complication (radiocystitis and radiorectitis). For BPH surgeries, during hospitalisation, laser-vaporisation (n = 5) was less haemorrhagic than TURP (n = 5) but after hospital discharge, 60% of patients presented a haemorrhagic complication with two readmissions and one surgical re-explorations. CONCLUSION: Performed in a specialised centre, prostate surgeries and interventions in patients with mild haemophilia is feasible with acceptable morbidity.

Prostate cancer detection by targeted prostate biopsy using the 3D Navigo system: a prospective study.

PURPOSE: The 3D Navigo™ system is a magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) fusion device for prostate targeted biopsies (TB). Our aim was to evaluate the clinically significant prostate cancer (CSC) detection rate of TB using the 3D Navigo™ system. METHODS: Patients who underwent TB with the 3D Navigo™ system in our center between June 2014 and May 2018 were prospectively included, excluding those who have previously received treatment for prostate cancer. A 3-Tesla MRI imaging was performed before biopsies; findings were reported according to the Prostate Imaging Reporting and Data System version 2 (PIRADS). CSC was defined by an ISUP score ≥ 2. RESULTS: 304 patients underwent TB. Median age was 66 years (51-84). Median PSA was 7.75 ng/ml (0.6-70.0). Median prostate volume was 45.0 ml (15.9-221.7). PCa and CSC were found in 70.4% (214/304) and 47.7% (145/304) of the patients, respectively. The proportion of patients diagnosed with CSC among those with PCa was 67.8% (145/214). There was a significant risk of having a CSC in case of PIRADS score ≥ 4 and 5 (OR 5.0, 95% CI [2.7-9.2], P < 0.001; OR 3.2, 95% CI [1.8-5.5], P < 0.001). PIRADS score was an independent risk factor of having a CSC (OR 4.19, 95% CI [2.49-7.05], P < 0.001). There was no significant difference between pathological outcomes of TB and RP in paired analysis (P = 0.892). There was a correlation between TB and RP specimens for PCa detection (r = 0.60, P < 0.001). CONCLUSION: Detecting CSC with MRI-TRUS fusion targeted biopsies using the 3D Navigo™ system is feasible and safe. We found a positive correlation between TB and RP for ISUP scores.

Erectile function after WST11 vascular-targeted photodynamic therapy for low-risk prostate cancer treatment.

Vascular-targeted photodynamic therapy (VTP) using padeliporfin is currently assessed as a low-risk prostate cancer (LRPCa) treatment. The aim of this study was to assess erectile function outcomes of VTP for LRPCa treatment. We prospectively included all patients treated with VTP for LRPCa. The primary endpoint was the post-treatment International Index of Erectile Function score (IIEF5 score) evolution (at 6 months, 12 months, and then every year for 5 years). Secondary endpoints were the need of erectile dysfunction (ED) treatment and its efficacy. Eighty-two men were included. The median follow-up was 68 (range: 6-89) months. There was a 3-point significant decrease in the median IIEF5 score between baseline and at 6 months post-VTP (23 [range: 1-25] vs 20 [range: 1-25], P = 0.005). There was a 1-point decrease at 1 year and 2 years post-VTP compared to baseline (22 [range: 2-25] and 22 [range: 0-25], P < 0.005). There was no significant difference at 3, 4, and 5 years compared to baseline. Twenty-seven (32.9%) patients received ED treatment: phosphodiesterase type-5 inhibitors (PDEI5; n = 18), intracavernous injections (ICI; n = 9), and intra-urethral gel (n = 1). The median IIEF5 score statistically significantly increased after ED treatment (7 [range: 0-24] vs 21 [range: 1-25], P < 0.001). ED treatment was efficient for 75% of the patients. There was no statistically significant difference between IIEF5 score at baseline and after ED treatment (P = 0.443). Forty-six patients were totally potent before VTP and among them, 13 needed ED treatment post-VTP with a success rate of 69.2%. VTP induced minimal changes in erectile function with a 3-point and a 1-point reduction in the IIEF5 score at 6 months and at 1 year, respectively. When required, ED treatment was efficient.
