Oncological outcome and complications of post-chemotherapy retroperitoneal surgery in non-seminomatous germ cell tumours - a systematic review.

INTRODUCTION: Post-chemotherapy surgery constitutes an integral part of the management of patients with non-seminomatous germ-cell tumours with a residual mass in the retroperitoneum. Published data on recurrence rates and complications to bilateral retroperitoneal lymph node dissection (RPLND), unilateral template RPLND, and resection of residual mass only according to different surgical techniques (open, laparoscopic, and robotic surgery) were reviewed. MATERIAL AND METHODS: PubMed/Medline, Embase, and the Cochrane databases were searched systematically. The risk of bias was assessed with the Newcastle Ottawa Scale. RESULTS: In total, 28 studies were included. Eight studies reported on open surgery with the bilateral template, seven on the unilateral template, and three on resection of mass only. Median follow-up was 39, 39, and 70 months, respectively. Recurrences were found in 11, 12, and 14%, respectively. Major complications (Clavien-Dindo III or more) were observed in 18, 8, and 17%, respectively. Two studies reported on laparoscopic bilateral surgery, eight on unilateral, and two on residual mass only. A total of Median follow-up was 52, 29, and 55 months, respectively. Recurrences were found in 0, 1, and 9%, respectively. Major complications were not documented for bilateral but were observed in 4% for unilateral and 0% for resection of tumour only. Four studies on robotic bilateral surgery, three on unilateral and two on resection of tumour only were included. Follow-up was 18, 35, and 30 months, respectively. Recurrences were found in 0, 0, and 2%, respectively. Major complications were observed in 0, 10. and 2%, respectively. CONCLUSIONS: When patient selection is made, recurrence rates for the open unilateral template are comparable to the bilateral template. The risk of complications is highest after an open bilateral template. Laparoscopic and robotic surgery should not be used as a standard procedure. More studies are required with larger patient populations and longer follow-up.

Postchemotherapy Retroperitoneal Lumpectomy in Patients with Nonseminoma Testicular Cancer: A Nationwide Study.

BACKGROUND AND OBJECTIVE: Optimal treatment outcomes in patients with metastatic nonseminoma testicular cancer are achieved with chemotherapy and subsequent surgery in cases with residual tumor. In Denmark, postchemotherapy retroperitoneal lumpectomy (RPLP) is performed in patients with residual tumors >1 cm. There is a need to clarify whether this surgical method provides acceptable treatment results. Our objective was to describe morbidity and oncological outcomes of postchemotherapy RPLP. METHODS: This was a retrospective population-based multicenter study including patients with nonseminoma testicular cancer and postchemotherapy RPLP performed in Denmark between 1990 and 2015. A total of 219 patients were eligible, with median follow-up of 19 yr. Postoperative complications were evaluated according to the Clavien-Dindo classification. The cumulative incidence of recurrence inside or outside the borders of a bilateral surgical template, progression-free survival (PFS), and overall survival estimates were calculated using the Kaplan-Meier method. KEY FINDINGS AND LIMITATIONS: After median follow-up of 19 yr, 31/219 patients (14%) experienced a surgical complication, of which 5% were Clavien-Dindo grade ≥III. In total, 37 patients experienced a recurrence. The 5-yr, 10-yr, and 20-yr cumulative risk of recurrence inside a bilateral template was 4.3%, 5.9%, and 5.9%, respectively. The 10-yr PFS rate was 83% and the 10-yr overall survival rate was 96%. The main limitation of the study is the retrospective design. CONCLUSIONS AND CLINICAL IMPLICATIONS: With few patients experiencing a major postoperative complication and a 10-yr cumulative rate of 5.9% for recurrence inside a bilateral surgical template, postchemotherapy RPLP appears to be a safe alternative to template surgery for disseminated nonseminoma. PATIENT SUMMARY: We looked at minimal surgery to remove tumor tissue remaining after chemotherapy in patients with testicular cancer. We found a low frequency of complications, tumor recurrence, and death.

Pheochromocytoma with spontaneous retroperitoneal bleeding.

In Denmark, the incidence of pheochromocytoma is 6.6 per million person-years. This case report describes a 33-year-old woman with a life-threatening adrenal bleeding. For some years prior to the incident she had suffered from hypertension, headache, palpitations, rapid increase of weight, oligomenorrhoea and hirsutism. The treatment was acute arterial embolisation. Subsequently, due to a persistently elevated level of methoxynoradrenaline she was diagnosed with pheochromocytoma. She was endocrinologically optimised, and the adrenal gland was removed laparoscopically.

Testicular cancer / Testicular cancer.

Testicular cancer is the most frequent solid tumour in young men and accounts for 1% of newly diagnosed malignant tumours. Tumours are divided into seminomas and non-seminomas. Approximately 50% of patients are cured by orchiectomy alone, while the other half in addition will need chemotherapy or radiotherapy for metastatic disease. Survival in patients treated for metastatic disease depends on prognostic criteria. Patients treated with systemic therapy have an increased risk of subsequent cancer and cardiovascular disease, as argued in this review.

Lower urinary tract injuries in patients with pelvic fractures at a level 1 trauma center - an 11-year experience.

BACKGROUND: Urological injuries can occur in patients with pelvic fractures. Treatment recommendations lack solid evidence and is often pragmatical. There is a continuous need to describe short- and long-term morbidity following lower urinary tract trauma. OBJECTIVE: To describe incidence, diagnosis, treatment, and morbidity following lower urinary tract injuries in pelvic fractures. PATIENTS AND METHODS: Retrospective study including patients with pelvic, including acetabular, fractures admitted to a Level I Trauma Centre covering 2.8 million citizens between 2009 and 2020. Outcome measurements comprised primary management, treatment trajectory, short- and long-term complications and outcomes. RESULTS: A total of 39 (5%) patients with pelvic fractures had concomitant urethral and/or bladder injuries, and one patient with an acetabular fracture had a bladder injury. The management of urethral injuries varied vastly, and complete urethral ruptures were associated with severe short- and long-term complications. Only one patient with bladder injury experienced severe long-term complications. CONCLUSIONS: Management of lower urinary tract injuries in patients with major pelvic fractures remains a major challenge. Special attention should be focused on urethral injuries where we uncovered an unsystematic treatment and follow-up even in a highly experienced centre, although this is also attributed to complicated multidisciplinary patient trajectories. There is a continuous need to reduce long-term complications following urethral trauma which should be addressed in multicenter studies.

Urethral pressure reflectometry; a novel technique for simultaneous recording of pressure and cross-sectional area: a study of feasibility in the prostatic urethra.

UNLABELLED: What's known on the subject? and What does the study add? In the 1980s and 1990s, a method for direct measurement of pressure and cross-sectional area in women and men was developed. It was successful in terms of obtaining meaningful results in several studies. But the technique, which was based on the field gradient principle, was never implemented in the clinical setting because of technical limitations. In 2005, urethral pressure reflectometry was introduced as a new technique in female urodynamics. The technique has been shown to be more reproducible than conventional urethral pressure profilometry, when measuring incontinence in women. In 2010 it was also introduced as a new measuring technique in the anal canal. This study, adds a new and interesting technique to the field of male urodynamics. For the first time, sound waves have been used to measure pressure and cross-sectional area simultaneously, directly in the prostatic urethra. The results from this first trial with urethral pressure reflectometry are promising, in terms of obtaining meaningful physiological parameters. Our hope is that, future trials will help us to be able to identify specific areas of obstruction or rigidity in the prostatic urethra, making treatment more direct and side effects from surgery less severe. However, further studies are needed to evaluate the technique with regards to clinical usefulness in men with benign prostatic obstruction. OBJECTIVE: Urethral Pressure Reflectometry (UPR) was introduced in 2005, and it has since been used in the female urethra for simultaneous measurement of pressure (P) and cross-sectional area (CA). It has shown to be more reproducible than conventional pressure measurement and reintroduced direct measurement of pressure and elastance in the urethra as important parameters when assessing incontinent women. To test the feasibility of UPR in the prostatic urethra. PATIENTS AND METHODS: We tested the technique in ten male patients, median age 73 and range 51-91. Measurements were performed in the supine position, with less than 50 ml of urine in the bladder. The UPR valuables measured were opening and closing pressure, opening and closing elastance and hysteresis. RESULTS: The PVC tube was easy to insert to the same degree as a normal KAD. Opening pressure and opening elastance were measured on all patients. The sphincter area was easily identified during measurements. UPR provides results compatible with previous techniques. A standardized method for measurements was developed. CONCLUSION: UPR has been shown feasible in the prostatic urethra. Further studies on healthy volunteers and patients with lower urinary tract symptoms and benign prostatic obstruction (BPO) are needed, to determine if UPR has a future role in urodynamic diagnostics of male patients with BPO.

Outcome and prognosis after adrenal metastasectomy: nationwide study.

BACKGROUND: Data regarding adrenal metastasectomy are limited. Here, clinical outcomes, safety, and prognostic factors in patients undergoing adrenal metastasectomy were evaluated in a large nationwide study. METHODS: Patients undergoing adrenal metastasectomy between 2000 and 2018 were identified in the Danish National Pathology Registry. Medical records were reviewed to confirm eligibility and to collect clinical data. The primary outcome was overall survival (OS). Cox multivariable regression analyses were? adjusted for baseline factors. RESULTS: In total, 435 patients underwent adrenal metastasectomy; the primary cancer origins were renal (n = 195, 45 per cent), lung (n = 121, 28 per cent), colorectal (n = 50, 11 per cent), and other (n = 69, 16 per cent). The median (interquartile range; i.q.r.) age was 66 (59-71) years, and 280 (64 per cent) were men. The 5-year OS was 31 per cent. The 30-day mortality was 1.8 per cent. Complications were more frequent and severe in patients who underwent open surgery compared with laparoscopic surgery (Clavien-Dindo III-V, 31.5 per cent versus 11.8 per cent respectively, P < 0.001). Factors associated with poor survival included non-radical pR2 resection (hazard ratio (HR) 3.57, 95 per cent c.i. 1.96 to 6.48), tumour size more than 50 mm (HR 1.79, 95 per cent c.i. 1.26 to 2.52), lung cancer origin (HR 1.77, 95 per cent c.i. 1.31 to 2.40), open surgical approach (HR 1.33, 95 per cent c.i. 1.04 to 1.71), presence of extra-adrenal metastases (HR 1.31, 95 per cent c.i. 1.01 to 1.71), and increasing Charlson co-morbidity index factors (HR 1.14 per one-point increase, 95 per cent c.i. 1.03 to 1.27). CONCLUSION: Adrenal metastasectomy is safe and may result in long-term survival in a subset of patients. Non-radical resection, large tumour size, lung cancer origin, open approach, presence of extra-adrenal metastases, and co-morbidity were associated with inferior outcomes.

DaPeCa-4: outcome in penile cancer patients with N3 disease due to extra nodal extension treated with surgery and chemo-irradiation.

Objective: The role of pelvic lymph node dissection (PLND) is still debated in patients with N3 stage penile cancer. In Denmark this subgroup of patients is in general managed with an inguinal lymphadenectomy (ILND) and adjuvant chemoradiation and PLND is not offered as a standard. The objective of this study was to report treatment outcomes of this regimen and compare this with existing literature.Materials and methods: We retrospectively reviewed records of patients with pT1-T4, N3, M0 penile cancer diagnosed between 1st January 2010 and 31th December 2014 in Denmark and treated with curative intend.Results: 21 patients were identified with a median follow up of 74 months (CI 54-94). Management of the penile lesion was local resection in 5 (23.8%), partial penectomy in 10 (47.6%), and total penectomy in 6 (28.6%) of patients. Regarding the most extensive lymph node (LN) surgery: 4 patients (23,8%) went directly to oncological treatment from sentinel node biopsy with no further LN dissection, 6 patients (28.6%) were treated with unilateral ILND, 10 patients (47.6%) with bilateral ILND and a single patient (4.8%) was treated with ILND and PLND. In the adjuvant setting patients were treated with external beam therapy of involved regions and cisplatin-based chemotherapy. Median overall survival was 84 months (CI 0-176). The 5-year probability of surviving penile cancer was 57.1% (CI 36.0-78.3).Conclusion: Treatment with surgery and chemo-irradiation in this national cohort does not show inferior survival outcomes compared to historical cohorts.

Urethral pressure reflectometry, a novel technique for simultaneous recording of pressure and cross-sectional area in the prostatic urethra: testing in men without bothersome lower urinary tract symptoms.

OBJECTIVE: Urethral pressure reflectometry (UPR) was introduced in 2005, for simultaneous measurement of pressure and cross-sectional area in the female urethra. It has shown to be more reproducible than conventional pressure measurement. Recently, it has been tested in the anal canal and the prostatic urethra. The primary aim of this study was to describe UPR in men without bothersome lower urinary tract symptoms. MATERIAL AND METHODS: The study investigated 18 men, median age 59 (range 50-77) with UPR and pressure-flow analyses (PQ), the International Prostate Symptom Score and the Danish version of Prostate Symptom Score, flow rate, residual urine measurements, transrectal ultrasound, urethral pressure profilometry and visual analogue scale (Discomfort). UPR parameters measured were opening and closing pressure, opening and closing elastance and hysteresis, from the bladder neck to the sphincter region. RESULTS: All UPR parameters increased significantly from the bladder neck to the sphincter region, except for the opening pressure between the prostate and the sphincter region. Seven men were obstructed according to PQ, but with no significant differences in any other standard urodynamic parameters. The hysteresis in the sphincter region was significantly lower in the obstructed group (p = 0.005). Discomfort was significantly lower with PQ compared to UPR (p = 0.04). Nine men had slight bleeding from the urethra during measurement with UPR. CONCLUSIONS: The increase in all parameters from the bladder neck to the sphincter region is consistent with previous studies measuring the same parameters. The hysteresis may explain why seven men were obstructed according to PQ.
