Seksuele disfunctie en relatieproblemen na prostaatkankerbehandeling: De gewenste zorg vanuit het oogpunt van patiënt en partner

Erectile dysfunction (ED) is one of the most common side effects of prostate cancer (PC) treatment and may lead to changes in a relationship. The aim of this study was to identify sexual and/or relational problems and to investigate what kind of supportive care is preferred by patients and their partners. A cross-sectional survey was performed among men diagnosed with PC enrolled in active surveillance or treated with laparoscopic radical prostatectomy, brachytherapy, intensity-modulated radiotherapy or hormonal therapy. If possible, partners were included as well. Out of 250 patients, 80,5% suffered from moderate to severe erectile complaints. Half of them (53,7%) was treated for ED and a great part was partially (30,7%) up to not satisfied (25,7%). Out of 168 partners, 50,6% found it difficult to cope with changes around sexuality. The majority of men (74,7%) preferred a standard consultation with a urologist-sexologist three months after treatment to discuss sexuality

Cribriform architecture in radical prostatectomies predicts oncological outcome in Gleason score 8 prostate cancer patients

The Gleason score is an important parameter for clinical outcome in prostate cancer patients. Gleason score 8 is a heterogeneous disease including Gleason score 3 + 5, 4 + 4, and 5 + 3 tumors, and encompasses a broad range of tumor growth patterns. Our objective was to characterize individual growth patterns and identify prognostic parameters in Gleason score 8 prostate cancer patients. We reviewed 1064 radical prostatectomy specimens, recorded individual Gleason 4 and 5 growth patterns as well as presence of intraductal carcinoma, and evaluated biochemical recurrence- and metastasis-free survival. Gleason score 8 disease was identified in 140 (13%) patients, of whom 76 (54%) had Gleason score 3 + 5, 46 (33%) 4 + 4, and 18 (13%) 5 + 3 disease. Invasive cribriform and/or intraductal carcinoma (n = 87, 62%) was observed more frequently in Gleason score 4 + 4 (93%) than 3 + 5 (47%; P < 0.001) and 5 + 3 (44%; P < 0.001) patients. Gleason pattern 5 was present in 110 (79%) men: as single cells and/or cords in 99 (90%) and solid fields in 32 (29%) cases. Solid field pattern 5 coexisted with cribriform architecture (23/32, 72%) more frequently than nonsolid pattern 5 cases (36/78, 46%, P = 0.02). In multivariable analysis including age, prostate-specific antigen, pT-stage, surgical margin status, and lymph node metastases, presence of cribriform architecture was an independent parameter for biochemical recurrence-free (hazard ratio (HR) 2.0, 95% confidence interval (CI) 1.0–3.7; P = 0.04) and metastasis-free (HR 3.5, 95% CI 1.0–12.3; P = 0.05) survival. In conclusion, invasive cribriform and/or intraductal carcinoma occurs more frequently in Gleason score 4 + 4 prostate cancer patients than in Gleason score 3 + 5 and 5 + 3, and is an independent parameter for biochemical recurrence and metastasis. Therefore, cribriform architecture has added value in risk stratification of Gleason score 8 prostate cancer patients

Cationic amphiphilic drugs as potential anticancer therapy for bladder cancer

More effective therapy for patients with either muscle-invasive or high-risk non-muscle-invasive urothelial carcinoma of the bladder (UCB) is an unmet clinical need. For this, drug repositioning of clinically approved drugs represents an interesting approach. By repurposing existing drugs, alternative anticancer therapies can be introduced in the clinic relatively fast, because the safety and dosing of these clinically approved pharmacological agents are generally well known. Cationic amp
