Comparative analysis of GOLPH3 expression in lymph node-positive prostate cancer: immunohistochemistry staining patterns and clinical significance

IntroductionProstate cancer (PCa) is the second most commonly diagnosed cancer in men worldwide. Lymph node metastasis is a poor prognostic factor for PCa. Previous studies have found that Golgi phosphoprotein 3 (GOLPH3) is overexpressed in various cancers, including PCa. We examined GOLPH3 expression in PCa cells from primary tumor and, as the first, also in metastatic lymph nodes to assess its potential as a new risk factor for PCa progression.MethodsThe study included 78 patients diagnosed with lymph node-positive PCa confirmed in the postoperative material. All the patients underwent radical prostatectomy (RP) with extended lymphadenectomy. The clinical data of the patients were retrospectively analyzed, and their histopathological specimens were selected for further analysis. Immunohistochemistry (IHC) staining was performed and the expression of GOLPH3 was assessed by an experienced uropathologist using an immunoreactive scale (IRS). A correlational analysis of the obtained data with the clinicopathological data of patients was performed.ResultsA positive IHC reaction for GOLPH3 was observed in all samples. IRS score for GOLPH3 expression was higher in the metastatic lymph nodes than in the prostate (not statistically significant; p=0.056). Several significant correlations were identified in connection with GOLPH3 expression levels in the prostate and metastatic lymph node tissues. No significant correlations were found between GOLPH3 expression and patient characteristics (e.g. BMI, EAU risk group, or preoperative PSA level), pathological features, or postoperative outcomes. However, we found that lymphovascular invasion (LVI) tended to be more common in patients with a higher percentage of GOLPH3-positive cells (p=0.02). We also found a positive association between the intensity of GOLPH3 staining in metastatic lymph nodes and the EAU classification. Finally, we found a significant negative correlation between the GOLPH3 expression and the efficacy of RP – the higher the expression of GOLPH3, the lower the efficacy of RP was (p<0.05).ConclusionGOLPH3 is expressed in both prostate and metastatic lymph nodes, with higher expression in metastatic lymph nodes. High GOLPH3 expression was associated with the occurrence of LVI, higher-risk group in the EAU classification, and lower efficacy of the RP, but there was no significant correlation with other pathological features or postoperative outcomes

Characteristics and Applications of Canine In Vitro Models of Bladder Cancer in Veterinary Medicine: An Up-to-Date Mini Review

Bladder cancer (BC) constitutes approximately 2% of all spontaneously occurring cancers in dogs. It is characterized by a devastating clinical course in most cases, which emphasizes a constant need for the development of novel methods of disease characterization and treatment. Over the past years, advances in cell engineering have resulted in the development of various canine in vitro models of BC, emerging as complements for in vivo research. In this article, we aimed to review the available data on existing in vitro models of canine BC, focusing primarily on their characteristics, applications in veterinary medicine, as well as advantages and disadvantages. The most commonly used in vitro models of canine BC comprise immortalized cell lines grown as adherent monolayers. They provide an unlimited supply of research material, however, they do not faithfully reflect the conditions prevailing in vivo, since the spatial cellular interactions are lost. The importance of the three-dimensional (3D) features of solid tumors in relation to carcinogenesis or drug response process has resulted in the development of the first canine 3D models of BC available for in vitro research. So far, results obtained with in vitro and in vivo research should be interpreted together. With the constantly growing complexity of in vitro models of BC cancer, animal-based research might be reduced in the future

Assessment of the Elastographic and Electromyographic of Pelvic Floor Muscles in Postmenopausal Women with Stress Urinary Incontinence Symptoms

Background. Shear wave elastography is an effective method for studying the condition of various musculoskeletal soft tissues. The primary aim of this study was the objective elastographic and electromyographic assessment of the pelvic floor during the rest and contraction of the pelvic floor muscles (PFM) in postmenopausal women. Methods. This was a prospective observational study that was carried out at the University Hospital in Wroclaw, Poland, between January 2017 and December 2019. Patients. The target group of the study included postmenopausal women with stress urinary incontinence. The primary outcomes were the features of the elastographic assessment of the pelvic floor during rest and contraction of the PFM obtained using shear wave elastography. Results. Based on the inclusion and exclusion criteria for the study, 14 patients took part in the measurements. There was a significant difference between the elastographic assessment of the pelvic floor during rest and contraction of the PFM at all locations in front of the urethra. No statistically significant correlation was found between the results of elastography and the bioelectrical activity of PFM. Conclusion. The elasticity of the periurethral structures is higher during active pelvic floor muscle contraction than at rest, it seems that shear wave elastography is an effective test that objectively assesses the strength of PFM contraction

Educational and Psychological Support Combined with Minimally Invasive Surgical Technique Reduces Perioperative Depression and Anxiety in Patients with Bladder Cancer Undergoing Radical Cystectomy

Radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) is an extensive and morbid operation, often associated with permanent alteration of body image and disability. Combined with the aggressive malignant potential of MIBC and considerable risk of complications, it poses a serious threat to the psychological well-being of patients. Educational deficiencies causing uncertainty and confusion aggravate surgery-related anxiety and may lead to depression along with further social disability. We conceived a preoperative supportive program named “Cystocare” held by urologists, psychologists, stoma therapists and cancer survivors to facilitate patients’ adaptation and coping. We aimed to evaluate whether participation in Cystocare meetings would alleviate emotional distress in patients undergoing RC. We included 95 consecutive patients who filled Hospital Anxiety and Depression Score questionnaires before RC and on discharge. The intervention arm (A) comprised 32 Cystocare participants. The remaining 63 patients who received standard preparation constituted the control arm (B). Whilst there were no differences in median anxiety and depression scores preoperatively, in postoperative measurement, the intervention arm showed a lower median depression score than controls: 3 vs. 8 points, p = 0.015. On multivariate analysis we confirmed lower risk of postoperative depression in Cystocare participants: OR = 0.215 (95%CI: 0.066–0.699), p = 0.011, along with lower odds of preoperative anxiety in patients undergoing laparoscopic RC: OR = 0.365 (95%CI: 0.136–0.978), p = 0.045, and higher risk of prolonged hospital stay in patients experiencing postoperative anxiety OR = 17.114 (95%CI: 1.283–228.234) p = 0.032. Preoperative educational and supportive intervention complements laparoscopic RC in the alleviation of surgery-related anxiety and depression. The support group meetings provide an attractive and cost-effective opportunity to moderate emotional response in patients undergoing RC, and as such, deserve widespread adoption

Diminishing the Gender-Related Disparity in Survival among Chemotherapy Pre-Treated Patients after Radical Cystectomy—A Multicenter Observational Study

There is a well-documented problem of inferior outcome of muscle-invasive bladder cancer (MIBC) after radical cystectomy (RC) in women. However, previous studies were conducted before neoadjuvant chemotherapy (NAC) was widely adopted to multidisciplinary management of MIBC. In our study, we assessed the gender-related difference in survival between patients who received NAC and those who underwent upfront RC, in two academic centers. This non-randomized, clinical follow-up study enrolled 1238 consecutive patients, out of whom 253 received NAC. We analyzed survival outcome of RC according to gender between NAC and non-NAC subgroups. We found that female gender was associated with inferior overall survival (OS), compared to males (HR, 1.234; 95%CI 1.046–1.447; p = 0.013) in the overall cohort and in non-NAC patients with ≥pT2 disease (HR, 1.220 95%CI 1.009–1.477; p = 0.041). However, no gender-specific difference was observed in patients exposed to NAC. The 5-year OS in NAC-exposed women in ≤pT1 and ≥pT2 disease, was 69.333% 95%CI (46.401–92.265) and 36.535% (13.134–59.936) respectively, compared to men 77.727% 95%CI (65.952–89.502) and 39.122% 95%CI (29.162–49.082), respectively. The receipt of NAC not only provides downstaging and prolongs patients’ survival after radical treatment of MIBC but may also help to diminish the gender specific disparity

The Influence of Lymph Node Count on Oncological Outcome of Radical Cystectomy in Chemotherapy Pre-Treated and Chemotherapy-Naïve Patients with Muscle Invasive Bladder Cancer

Radical cystectomy (RC) with pelvic lymph node dissection (PLND) remains the mainstay of treatment for muscle-invasive bladder cancer (MIBC). The extent of PLND and number of removed lymph nodes (LNs) have been associated with improved staging and survival outcomes in several series of RC patients. Neoadjuvant chemotherapy (NAC) has become standard of care for cisplatin-eligible patients qualified to RC, yet few studies on PLND stratified cases according to the receipt of NAC. We aimed to address this issue and reevaluate the prognostic value of PLND nodal yields in series of patients who underwent RC on the verge of the NAC era. This single-center, retrospective, clinical follow-up study enrolled 439 consecutive patients, out of whom 83 received NAC. We analyzed survival outcome of RC according to the number of removed nodes between NAC and non-NAC subgroups. We found PLND thresholds of 10 and 15 LNs prognostically meaningful in our study cohort, and this association was particularly pronounced in the non-NAC subgroup. Higher numbers of LNs provided a 25% reduction in risk of all-cause mortality and correspondingly correlated with up to a 14% increase in 3-year overall survival. The receipt of NAC diminished the benefit of adequate PLND, as the number of retrieved LNs was not associated with survival in the NAC-RC cohort. Given the limitations of our study, additional research is needed to verify these findings

Urological Manifestations of the Systemic Vasculitides—A Scoping Review

Background: Vasculitides are specific inflammations of the blood vessel wall that can take place in any organ system of the human body. They may occur as a primary process (primary systemic vasculitides, PSV) or may be secondary to another underlying disease. In general, in association with the specific type of vasculitis, affected vessels vary in size, type, and location. In the following scoping review, we present clinical characteristics and manifestations of PSV with reference to the genitourinary system. Materials and methods: A non-systematic search of the relevant literature was conducted using three electronic databases (PubMed, Embase, and Web of Science) up to 29 October 2021. Results: Urogenital manifestations of PSV are infrequent, with the most commonly reported findings as prostatic or testicular involvements. However, almost all other organs of the genitourinary system can be affected. Conclusions: Because of the clinical heterogeneity and non-specific symptoms, the proper diagnosis of PSV is often delayed and constricted. Fast identification of urological manifestations of vasculitides is essential in implementing appropriate therapy and avoiding unnecessary, harmful, and invasive surgery
