Inflammatory Myofibroblastic Bladder Tumor in a Patient with Von Recklinghausen's Syndrome
Myofibroblastic tumor, also known as inflammatory pseudotumor or pseudosarcoma, is a benign tumor with mesenchymal origin. Bladder location is very uncommon. We report the case of a 58-year-old man with a history of von Recklinghausen's disease who complained for painless macroscopic hematuria 5 months after suprapubic prostatectomy. The radiograph evaluation revealed a bladder tumor, and the pathologic examination following a transurethral resection showed inflammatory myofibroblastic tumor of the bladder. The patient finally underwent a radical cystectomy due to the uncertain pathogenesis of inflammatory myofibroblastic tumor as well as the rarity of cases published on bladder tumors in Von Recklinghausen's patients
Diagnosis and management of intradiverticular bladder tumours: A pooled analysis of 498 cases
Objective: Intradiverticular bladder tumors (IDBT) are uncommon clinical entities. We reviewed the literature for clinical presentation, diagnosis and therapeutic options to establish recommendations for diagnostic and therapeutic management.
Methods: Bibliographic research was performed using PubMed from database inception until October 15, 2022. A pooled analysis was performed of 498 patients with IDBT presented in the literature. The evaluation included patient sex, age, diagnostic methods, symptoms, localization of the tumor, tumor staging, tumor histopathology, treatment, and the presence of recurrence. To express results, descriptive statistics were used appropriately.
Results: The mean age at diagnosis was 64.81 years (range 49 days to 84 years). The ratio between men and women was ≈ 24:1, suggesting a male predominance (85% male, 3.6% female). The most common presenting symptom was gross hematuria (60.88%). Most of the patients had cystoscopy (56.85%) and intravenous or computed tomography urography (52.01%). Regarding tumor staging, most of the patients were diagnosed with pT1 tumors. For the histopathology of IDBT, 87.95% of the specimens were transitional cell carcinomas and in 10.84% there were concomitant CIS. Regarding the treatment, radical cystectomy was chosen in 34.34%, partial cystectomy in 26.66%, diverticulectomy in 15.95% and transurethral resection of bladder tumour (TURBT) in 16.36% of the patients.
Conclusions: Most common diagnostic tool for IDBT seems to be cystoscopy followed by computerized tomography urogram. Due to the absence of muscle layer in the diverticulum and the highgrade histology of most of them at diagnosis, cystectomy is the first therapeutic choice. However, for patients that are not considered appropriate candidates or for those presenting with lowgrade and low volume tumors, TURBT is a good option
Current Options for Second-Line Systemic Therapy in Metastatic Renal Cell Carcinoma
Standard systemic therapy of advanced renal cell carcinoma (RCC) involves targeting angiogenesis, mainly through tyrosine kinase inhibitors (TKI) against the vascular endothelial growth factor receptor (VEGFR) pathway and targeting the immune checkpoints, namely, programmed death-1 (PD-1) or its ligand (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA4). With current strategies of combining these two approaches in the front-line setting, less is known about optimal selection of therapy upon development of resistance in the second and later lines of treatment for progressive disease. This review discusses currently available therapeutic options in patients who have progressive RCC after prior treatment with double immune check-point inhibitors (ICIs) or ICI-TKI combinations
Cytoreductive nephrectomy for synchronous metastatic renal cell carcinoma. Is there enough evidence?
Objective: To assess the role of Cytoreductive Nephrectomy for synchronous metastatic Renal Cell Carcinoma patients in the Systemic Therapy era and beyond regarding the Overall Survival, the optimal sequence between Systemic Therapy and Cytoreductive Nephrectomy and prognostic factors.
Methods: The systematic review was conducted in accordance with the PRISMA guidelines. Bibliographic search was performed in Medline (PubMed), ClinicalTrials.gov, and Cochrane Library-Cochrane Central Register of Controlled Trials (CENTRAL). Studies included were those indexed from 2005 in an attempt to limit those conducted in the cytokine era. Risk of bias assessment was performed by two authors (K.S and T.L) using the Cochrane Collaborative Risk of Bias tool for randomized trials, the Cochrane Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for nonrandomized studies.
Results: Cytoreductive nephrectomy was associated with improved overall survival in all but one of the observational studies. While in all of these studies the unvariable analysis showed improved overall survival in favor of the cytoreductive nephrectomy group in some studies the subgroup analysis showed no benefit. Regarding the optimal sequence, deferred cytoreductive nephrectomy demonstrated better results in more studies than upfront cytoreductive nephrectomy but a advantage was not clearly certain. In the analysis of possible prognostic factors for overall survival with cytoreductive nephrectomy, most common prognostic factors found were age (in 8 studies), tumor histology (in 7 studies), number of metastasis (in 6 studies), and T stage.
Conclusions: Cytoreductive nephrectomy can still play an important role in wisely selected patients, although the role of cytoreductive nephrectomy in the new immunotherapy era needs to be defined
Surgical techniques to preserve continence after robot-assisted radical prostatectomy
Radical prostatectomy significantly impacts the inherent anatomy of the male pelvis and the functional mechanisms of urinary continence. Incontinence has a considerable negative influence on the quality of life of patients, as well as their social and psychological wellbeing. Numerous surgical techniques have been demonstrated to support the preservation of continence during robot-assisted radical prostatectomy (RARP). In this in-depth analysis, we give a general summary of the surgical techniques used in RARP and their impact on incontinence rates
Obstruction-induced alterations within the urinary bladder and their role in the pathophysiology of lower urinary tract symptomatology
Benign prostatic hyperplasia (BPH) is considered a frequent cause of
bladder outlet obstruction (BOO) and lower urinary tract symptoms. This
review addresses the bladder response to BOO and focuses on the
alterations and biochemical adaptability of the bladder wall in the
presence of hypoxia. A literature review of published articles has been
performed, including both in vivo and in vitro studies on human and
animal tissue
A case of penile strangulation after placement of metallic rings
Penile strangulation following placement of metallic rings is a rare clinical entity that needs urgent attention to avoid potentially severe clinical consequences. Careful handling and occasionally a multidisciplinary approach are the keys to a successful outcome
Relugolix: A new kid on the block among gonadotrophin-releasing hormone antagonists
Androgen-deprivation therapy (ADT) is the cornerstone of metastatic
prostate cancer treatment. ADT can be achieved through surgical
castration, or it may be induced either by gonadotrophin-releasing
hormone (GnRH) agonists or GnRH antagonists. GnRH antagonists provide a
more rapid castration alongside with a safer profile regarding adverse
events. Degarelix is the sole GnRH antagonist used in clinical practice.
Injection site reactions are the commonest adverse events related to the
use of degarelix. Relugolix, a novel molecule, represents the first
orally administered United States Food and Drug Administration approved
GnRH antagonist, with clinical efficacy equal to that of the established
ADT regimens. The main advantages of relugolix are the avoidance of the
injection site reactions of GnRH antagonists such as degarelix alongside
its patient-friendly oral administration. The aim of the present review
article is to present novel data regarding the role of relugolix as ADT
for the treatment of prostate cancer
