RESUMEN

Bladder cancer accounts for nearly 170,000 deaths worldwide annually. For over 4 decades, the systemic management of muscle-invasive and advanced bladder cancer has primarily consisted of platinum-based chemotherapy. Over the past 10 years, innovations in sequencing technologies have led to rapid genomic characterization of bladder cancer, deepening our understanding of bladder cancer pathogenesis and exposing potential therapeutic vulnerabilities. On the basis of its high mutational burden, immune checkpoint inhibitors were investigated in advanced bladder cancer, revealing durable responses in a subset of patients. These agents are now approved for several indications and highlight the changing treatment landscape of advanced bladder cancer. In addition, commonly expressed molecular targets were leveraged to develop targeted therapies, such as fibroblast growth factor receptor inhibitors and antibody-drug conjugates. The molecular characterization of bladder cancer and the development of novel therapies also have stimulated investigations into optimizing treatment approaches for muscle-invasive bladder cancer. Herein, the authors review the history of muscle-invasive and advanced bladder cancer management, highlight the important molecular characteristics of bladder cancer, describe the major advances in treatment, and offer future directions for therapeutic development.

RESUMEN

PURPOSE: Vaginal oestrogens can be used to treat genitourinary symptoms in women with early breast cancer. Studies evaluating vaginal oestrogens have commonly measured serum oestrogen levels as a surrogate marker of safety, but methods vary. We sought to summarise the data on serum oestrogen measurement in women with breast cancer using vaginal oestrogens to better understand the methods, levels and reliability. METHODS: We searched Medline, Embase, CENTRAL, SCOPUS and CINAHL from inception to October 2023 for clinical studies where serum oestrogen was measured in women with a history of early breast cancer using vaginal oestrogens. Studies with a reported testing methodology were included. RESULTS: Nine studies met the inclusion criteria for this systematic review. Methods used to measure oestradiol and oestriol in selected studies included mass spectrometry and immunoassays; several studies used more than one with variable concordance. Mass spectrometry detected oestradiol levels down to a lower limit between 1.0 pg/mL and 3.0 pg/mL. Immunoassays such as ELISA (enzyme-linked immunosorbent assay), ECLIA (enhanced chemiluminiscence immunoassay) and RIA (radioimmunoassay) had lower detection limits ranging between 0.8 pg/mL and 10 pg/mL. Studies were heterogeneous in testing techniques used, timing of testing, and the population including with subsequent varying results in the effect on oestrogens reported. CONCLUSIONS: Adopting consistent and standardised methods of measuring oestrogens in clinical trials involving women with early breast cancer on vaginal oestrogens is critical. Serum oestrogens are used as a surrogate marker of safety in this population, and good-quality data are necessary to enable clinicians and patients to feel confident in prescribing and taking vaginal oestrogens. Mass spectrometry, although more expensive, gives more reliable results when dealing with very low levels of oestrogens often found in women on aromatase inhibitors, compared to immunoassays.

RESUMEN

A small subset of testicular sex cord-stromal tumors, designated as Sertoli-stromal cell tumors (SSCTs), comprises a mixture of Sertoli, spindle, and/or Leydig cells. The clinicopathologic features of these tumors have not been studied in any detail, and their molecular features are unknown. We, therefore, assessed the morphologic and genomic features of 14 SSCTs, including 1 tumor with features similar to the ovarian Sertoli-Leydig cell tumor (SLCT) with retiform tubules. The median age of the patients was 24 years (range, 10-55 years), and the median tumor size was 2.3 cm (range, 0.7-4.7 cm). All tumors showed Sertoli-like sex cord cells arranged in variably developed tubular structures, typically also forming nests and cords. These imperceptibly blended with a neoplastic spindle cell stroma or, in the SLCT, vacuolated to eosinophilic Leydig cells. Genomic analysis demonstrated the presence of a hotspot loss-of-function DICER1 mutation in the SLCT (patient 1) and hotspot gain-of-function CTNNB1 mutations in the tumors of patients 2 and 3, with both CTNNB1 variants being interpreted as possible subclonal events. The mutations were the only relevant findings in the tumors of patients 1 and 2, whereas the tumor of patient 3 harbored concurrent chromosomal arm-level and chromosome-level copy number gains. Among the remaining 11 tumors, all of those that had interpretable copy number data (9 tumors) harbored multiple recurrent chromosomal arm-level and chromosome-level copy number gains suggestive of a shift in ploidy without concurrent pathogenic mutations. The results of the present study suggest that CTNNB1 mutations (likely subclonal) are only rarely present in SSCTs; instead, most of them harbor genomic alterations similar to those seen in testicular sex cord-stromal tumors with pure or predominant spindle cell components. A notable exception was a testicular SLCT with morphologic features identical to the ovarian counterpart, which harbored a DICER1 mutation.

RESUMEN

Cervical cancer (CC) is the fourth most common cancer among female patients. The primary cause of all types of cervical cancer is human papillomavirus (HPV), which was projected to account for 5,70,000 reported cases in 2018. Two HPV strains (16 and 18) account for 70 % of cervical abnormalities and precancerous cervical cancers. CC is one of the main causes of the 17 % cancer-related death rate among Indian women between the ages of 30 and 69 is CC. The side effects of the currently approved treatments for cervical cancer could endanger the lives of women affected by the illness. Thus, probiotics may be extremely important in the management of CC. Numerous studies on probiotics and their potential for use in cancer diagnosis, prevention, and treatment have been conducted. This review describes the enhancement of the immune system, promotion of a balanced vaginal microbiome, and decreased risk of secondary infections, which have anti-inflammatory effects on the body. Probiotics have the potential to reduce inflammation, thereby adversely affecting cancer cell growth and metastasis. During the course of antibiotic therapy, they support a balanced vaginal microbiome. Oncogenic virus inactivation is possible with probiotic strains. In postmenopausal women, the use of vaginal probiotics helps lessen menopausal symptoms caused by Genitourinary Syndrome of Menopause (GSM). The antitumor effects of other medications can be enhanced by them as potential agents, because they can both promote the growth of beneficial bacteria and reduce the quantity of potentially harmful bacteria. The development of tumors and the proliferation of cancer cells may be indirectly affected by the restoration of the microbial balance. Probiotics may be able to prevent and treat cervical cancer, as they seem to have anticancer properties. To identify probiotics with anticancer qualities that can supplement and possibly even replace traditional cancer treatments, further investigation is required, including carefully planned clinical trials.

RESUMEN

BACKGROUND: Female sexual dysfunction (FSD), defined as clinically distressing problems with desire, arousal, orgasm, or pain, affects 12% of US women. Despite availability of medications for FSD, primary care physicians (PCPs) report feeling underprepared to manage it. In contrast, erectile dysfunction (ED) is frequently treated in primary care. OBJECTIVE: To describe differences in patterns of FSD and ED diagnosis and management in primary care patients. DESIGN: Retrospective observational study. SUBJECTS: Primary care patients with an incident diagnosis of FSD or ED seen at a large, integrated health system between 2016 and 2022. MAIN MEASURES: Sexual dysfunction management (referral or prescription of a guideline-concordant medication within 3 days of diagnosis), patient characteristics (age, race, insurance type, marital status), and specialty of physician who diagnosed sexual dysfunction. We estimated the odds of FSD and ED management using mixed effects logistic regression in separate models. KEY RESULTS: The sample included 6540 female patients newly diagnosed with FSD and 16,591 male patients newly diagnosed with ED. Twenty-two percent of FSD diagnoses were made by PCPs, and 38% by OB/GYNs. Forty percent of ED diagnoses were made by PCPs and 20% by urologists. Patients with FSD were managed less frequently (33%) than ED patients (41%). The majority of FSD and ED patients who were managed received a medication (96% and 97%, respectively). In the multivariable models, compared to diagnosis by a specialist, diagnosis by a PCP was associated with lower odds of management for FSD patients (aOR, 0.59; 95% CI, 0.51-0.69) and higher odds of management (aOR, 1.52; 95% CI, 1.36-1.64) for ED patients. CONCLUSIONS: Primary care patients with FSD are less likely to receive management if they are diagnosed by a PCP than by an OB/GYN. The opposite was true of ED patients, exposing a gap in the quality of care female patients receive.

RESUMEN

BACKGROUND: Genitourinary sarcomas are rare in adults and few large-scale studies on adult genitourinary sarcoma are reported. We aimed to elucidate the clinical characteristics, survival outcomes, and prognostic factors for overall survival of adult genitourinary sarcoma in Japan. METHODS: A hospital-based cancer registry data in Japan was used to identify and enroll patients diagnosed with genitourinary sarcoma in 2013. The datasets were registered from 121 institutions. RESULTS: A total of 116 men and 39 women were included, with a median age of 66 years. The most common primary site was the kidney in 47 patients, followed by the paratestis in 36 patients. The most common histological type was liposarcoma in 54 patients, followed by leiomyosarcoma in 25 patients. The 5-year overall survival rates were 57.6%. On univariate analysis, male gender, paratestis as primary organ, and histological subtype of liposarcoma were predictive of favorable survival while primary kidney, bladder, or prostate gland location were predictive of unfavorable survival. On multivariate analysis, primary paratestis was an independent predictor of favorable survival while primary kidney, bladder, or prostate gland were independent predictors of unfavorable survival. CONCLUSIONS: This is the first report showing the clinical characteristics and survival outcomes of adult genitourinary sarcoma in Japan using a real-world large cohort database.

RESUMEN

PURPOSE OF REVIEW: The aim of this review is to focus on epidemiology, pathogenesis, risk factors, management, and complications of UTI in people with diabetes as well as reviewing the association of SGLT-2 inhibitors with genitourinary infections. RECENT FINDINGS: Individuals diagnosed with T2DM are more prone to experiencing UTIs and recurrent UTIs compared to individuals without T2DM. T2DM is associated with an increased risk of any genitourinary infections (GUI), urinary tract infections (UTIs), and genital infections (GIs) across all age categories. SGLT2 inhibitors are a relatively new class of anti-hyperglycemic agents, and studies suggest that they are associated with an increased risk of genitourinary infections. The management of diabetes and lifestyle modifications with a patient-centric approach are the most recognized methods for preventing critical long-term complications including genitourinary manifestations of diabetes. The available data regarding the association of SGLT-2 inhibitors with genitourinary infections is more comprehensive compared to that with UTIs. Further research is needed to better understand the mechanisms underlining the association between SGLT-2 inhibitors and genital infections and UTIs.

RESUMEN

INTRODUCTION/AIMS: Anecdotally, patients with facioscapulohumeral muscular dystrophy (FSHD) describe gastrointestinal (GI) and genitourinary (GU) symptoms. We explored the prevalence of GI and GU symptoms and their impact on quality of life (QOL) in people with FSHD compared to healthy household controls. METHODS: In this descriptive, cross-sectional study, we emailed a survey exploring GI and GU symptoms to all FSHD Society patient contacts (n = 3507). We invited those with FSHD and unaffected household controls to respond. Non-parametric statistics were used to compare symptom frequency and impact of symptoms between respondents with FSHD and household controls. Within the FSHD group, symptom frequency was assessed relative to measures of disease progression (need for ambulatory or respiratory support). RESULTS: Surveys from 701 respondents (652 with FSHD) ≥18 years old were included in analysis. Those with FSHD had symptoms affecting both GI and GU systems more frequently than controls using ordinal rating of symptom frequency. Within the FSHD group, more advanced disease was associated with increased symptom frequency. QOL was negatively impacted by the GI and GU symptoms. There was no difference between groups in use of medications to treat these symptoms. DISCUSSION: Recognition and treatment of GI and GU symptoms in people with FSHD, particularly those with more advanced disease, could improve QOL. Additional investigation is required to confirm these findings and understand the physiology.

RESUMEN

BACKGROUND: As the muscular and connective tissue components of the vagina are estrogen responsive, clinicians may recommend vaginal estrogen to optimize tissues preoperatively and as a possible means to reduce prolapse recurrence, but long-term effects of perioperative intravaginal estrogen on surgical prolapse management are uncertain. OBJECTIVE: This study aimed to compare the efficacy of perioperative vaginal estrogen vs placebo cream in reducing composite surgical treatment failure 36 months after native tissue transvaginal prolapse repair. STUDY DESIGN: This was an extended follow-up of a randomized superiority trial conducted at 3 tertiary US sites. Postmenopausal patients with bothersome anterior or apical vaginal prolapse were randomized 1:1 to 1-g conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally twice weekly for ≥5 weeks preoperatively and continued twice weekly for 12 months postoperatively. All participants underwent vaginal hysterectomy (if the uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The primary report's outcome was time to failure by 12 months postoperatively, defined by a composite outcome of objective prolapse of the anterior or posterior walls beyond the hymen or the vaginal apex descending below one-third the total vaginal length, subjective bulge symptoms, and/or retreatment. After 12 months, participants could choose to use-or not use-vaginal estrogen for atrophy symptom bother. The secondary outcomes included Pelvic Organ Prolapse Quantification points, subjective prolapse symptom severity using the Patient Global Impression of Severity and the Patient Global Impression of Improvement, and prolapse-specific subscales of the 20-Item Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire-Short Form 7. Data were analyzed as intent to treat and "per protocol" (ie, ≥50% of expected cream use per medication diary). RESULTS: Of 206 postmenopausal patients, 199 were randomized, and 186 underwent surgery. Moreover, 164 postmenopausal patients (88.2%) provided 36-month data. The mean age was 65.0 years (standard deviation, 6.7). The characteristics were similar at baseline between the groups. Composite surgical failure rates were not significantly different between the estrogen group and the placebo group through 36 months, with model-estimated failure rates of 32.6% (95% confidence interval, 21.6%-42.0%) and 26.8% (95% confidence interval, 15.8%-36.3%), respectively (adjusted hazard ratio, 1.55; 95% confidence interval, 0.90-2.66; P=.11). The results were similar for the per-protocol analysis. Objective failures were more common than subjective failures, combined objective and subjective failures, or retreatment. Using the Patient Global Impression of Improvement, 75 of 80 estrogen participants (94%) and 72 of 76 placebo participants (95%) providing 36-month data reported that they were much or very much better 36 months after surgery (P>.99). These data included reports from 51 of 55 "surgical failures." Pelvic Organ Prolapse Quantification measurements, Patient Global Impression of Severity scores, and prolapse subscale scores of the 20-Item Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire-Short Form 7 all significantly improved for both the estrogen and placebo groups from baseline to 36 months postoperatively without differences between the groups. Of the 160 participants providing data on vaginal estrogen usage at 36 months postoperatively, 40 of 82 participants (49%) originally assigned to the estrogen group were using prescribed vaginal estrogen, and 47 of 78 participants (60%) assigned to the placebo group were using vaginal estrogen (P=.15). CONCLUSION: Adjunctive perioperative vaginal estrogen applied ≥5 weeks preoperatively and 12 months postoperatively did not improve surgical success rates 36 months after uterosacral or sacrospinous ligament suspension prolapse repair. Patient perception of improvement remained very high at 36 months.

RESUMEN

BACKGROUND: Vulvovaginal atrophy (VVA) negatively affects the sexual well-being and quality of life of postmenopausal women, yet it is underreported and undertreated. AIM: The study sought to investigate the efficacy and safety of a nonablative, noncoagulative multipolar radiofrequency (RF) and pulsed electromagnetic field-based device (PEMF) in treatment of symptoms related to VVA. METHODS: Seventy-six women ≥19 years of age with symptoms associated with VVA were enrolled into this prospective, randomized, sham-controlled, multicenter clinical study. Subjects were randomized to receive 3 RF + PEMF treatments (active group) or sham treatments (sham group) delivered to vaginal tissue at monthly intervals. The Vaginal Health Index (VHI), along with the Female Sexual Function Index (FSFI), subject sexual satisfaction and vaginal laxity (VL) score, treatment-associated pain, and adverse events were assessed at 4 follow-up (FU) visits between 1 and 12 months after treatment. OUTCOMES: Changes from baseline VHI, pH, FSFI, VL, and sexual satisfaction scores between the active and sham groups were compared before and after treatment. RESULTS: Mean VHI scores in the active group were significantly better compared with the sham group after treatment at all but the last FU visit (P < .001). A greater decrease in pH (active over sham) was seen at 1 and 4 months after treatment (P < .05). FSFI improvement was shown in the active group; however, it was not significantly better than sham improvement at all FU visits. Subject sexual satisfaction in the active group showed better improvement over sham at all FU visits (P < .05), while VL evaluations saw greater improvement in the active group at 4, 6, and 12 months posttreatment (P < .05). Treatment satisfaction was greater in the active group and pain was minimal in both groups. No serious adverse effects were reported. CLINICAL IMPLICATIONS: As a noninvasive alternative to traditional surgical and topical procedures, 3 sessions of noninvasive combination RF/PEMF safely demonstrated improvement in symptoms related to VVA. STRENGTHS AND LIMITATIONS: This study was strengthened by the randomized, sham-controlled design; large sample size; and extended FU period. The study assessments were decreased at later FU visits due to the global COVID pandemic, and this was a key limitation to the study. CONCLUSION: Nonablative, noncoagulative multipolar RF/PEMF therapy was safe, improved symptoms associated with VVA, and improved female sexual function while yielding high subject satisfaction.

RESUMEN

BACKGROUND: Current practices in nephrostomy exchange are guided by institutional or societal expert-consensus rather than evidence-based recommendations. OBJECTIVE: To examine the temporal distribution of exchanges and assess whether the observed distributions align with institutional, or expert-recommended guidelines where routine exchanges would be expected to occur within 60-89 days. Non-routine exchanges would be expected to occur either after 60 days or after 89 days. METHODS: Data were collected from the Merative™ MarketScan Commercial Claims and Encounters Databases and included all patients who underwent a PCN exchange from 2009 to 2021. The dataset was queried using ICD-9/10 and CPT coding systems. Outpatient exchanges were classified as routine exchanges, whereas inpatient exchanges were classified as non-routine exchanges. Chi-Square Goodness-of-Fit tests were used to compare observed frequencies against expected distributions of routine exchanges within the 59-89 day window, and non-routine exchanges to occur after either 60 or after 89 days. RESULTS: There was a total of 19,689 exchanges: of those, 41% (n = 8,058) exchange encounters occurred within 29 days, 67% (n = 13,213) occurred within 59 days, and 81% (n = 15,899) occurred within 89 days. Routine exchanges accounted for 76% of total exchanges: of those routine exchanges, 39% (n = 5,863) of routine exchanges occurred within 29 days, 67% (n = 10,057) occurred within 59 days, and 82% (n = 12,256) occurred within 89 days. Non-routine exchanges account for 24% of all exchanges in the study cohort. Of all non-routine exchanges (n = 4,737), 46% (n = 2,035) of non-routine exchange encounters occurred within 29 days, 67% (n = 3,156) within 60 days, and 77% (n = 3,643) within 89 days. Chi-square tests indicated significant deviations from the expected distributions for both routine (p < 0.01) and non-routine (p < 0.01) exchanges. CONCLUSION: A significant proportion of routine exchanges occur outside a 60-89 day window, and with a majority of routine exchange observations occurring prior to 59 days. A significant proportion of non-routine exchanges occur prior to 60 days and prior to 89 days. CLINICAL IMPACT: Significant disparities between existing guidelines and clinical practice, underscoring the need for evidence-based guidelines to reduce complication rates, improve patient outcomes, and reduce the burden of cost on the healthcare system.

RESUMEN

OBJECTIVES: Whether vaginal estradiol use is associated with an increased risk of recurrent venous thromboembolism (VTE) in women with prior VTE is unknown. We sought to evaluate the association between vaginal estradiol use and recurrent VTE in women with prior VTE. METHODS: We performed a nationwide nested case-control study among 44 024 women aged ≥45 years who developed a first VTE without a history of vaginal estrogen use prior to VTE diagnosis. Cases with recurrent VTE were matched 1:2 on birth year with controls using incidence density sampling. Exposure to vaginal estradiol tablets was categorized into current use (0-2 months before index), prior use (2-24 months before index) and past use (more than 24 months prior to index). RESULTS: We identified 5066 cases and 10 127 age-matched controls. In fully adjusted analysis vaginal estrogen was not associated with recurrent VTE with a hazard ratio of 0.75, p = .07 for current use, 0.83, p = .13 for prior use, and 1.24, p = .06 for past use. CONCLUSION: Use of vaginal estradiol tablets in women with prior VTE was not associated with an increased rate of recurrent VTE. Our study indicates that vaginal estradiol therapy is unlikely to increase risk of recurrent VTE in women with prior VTE.

RESUMEN

INTRODUCTION: The American Urological Association guidelines recommend against the performance of ultrasound and other imaging modalities in the evaluation of patients with cryptorchidism before expert consultation. We aimed to examine our institutional experience with cryptorchidism and measure adherence to currently available guidelines. METHODS: An institutional review board-approved retrospective review of ultrasound utilization in the evaluation of patients with cryptorchidism was performed from June 1, 2016, to June 30, 2019, at a single tertiary level pediatric hospital. RESULTS: We identified 1796 patients evaluated in surgical clinics for cryptorchidism. Surgical intervention was performed in 75.2% (n = 1351) of the entire cohort. Ultrasound was performed in 42% (n = 754), most of which were ordered by referring physicians (91% n = 686). Of those who received an ultrasound, surgical intervention was performed in 78% (n = 588). Those 166 patients (22%) who did not undergo surgical intervention were referred with ultrasounds suggesting inguinal testes; however, all had normal physical examinations or mildly retractile testes at the time of consultation and were discharged from the outpatient clinic. There were 597 patients referred without an ultrasound, 81% (n = 483) were confirmed to have cryptorchidism at the time of specialist physical examination and underwent definitive surgical intervention, the remainder (19%, n = 114) were discharged from the outpatient clinics. CONCLUSIONS: Ultrasound evaluation of cryptorchidism continues despite high-quality evidence-based guidelines that recommend otherwise, as they should have little to no bearing on the surgeon's decision to operate or the type of operation. Instead, physical examination findings should guide surgical planning.

RESUMEN

Neuroendocrine (NE) cells comprise ~1% of epithelial cells in benign prostate and prostatic adenocarcinoma (PCa). However, they become enriched in hormonally treated and castration-resistant PCa (CRPC). In addition, close to 20% of hormonally treated tumors recur as small cell NE carcinoma (SCNC), composed entirely of NE cells, which may be the result of clonal expansion or lineage plasticity. Since NE cells do not express androgen receptors (ARs), they are resistant to hormonal therapy and contribute to therapy failure. Here, we describe the identification of glypican-3 (GPC3) as an oncofetal cell surface protein specific to NE cells in prostate cancer. Functional studies revealed that GPC3 is critical to the viability of NE tumor cells and tumors displaying NE differentiation and that it regulates calcium homeostasis and signaling. Since our results demonstrate that GPC3 is specifically expressed by NE cells, patients with confirmed SCNC may qualify for GPC3-targeted therapy which has been developed in the context of liver cancer and displays minimal toxicity due to its tumor-specific expression. © 2023 The Pathological Society of Great Britain and Ireland.

RESUMEN

BACKGROUND: Patients with type 2 diabetes (T2D) are at an increased risk of genital urinary (GU) infections, with the risk increasing with higher A1Cs. Given the broad adoption of sodium-glucose co-transporter 2 inhibitors (SGLT2is) in patients with T2D, both providers and patients need to be aware of common adverse effects associated with these medications, specifically GU infections. However trials involving SGLT2is looked at patients with an average A1C of less than 9%, and thus, the incidence of GU infections may not truly reflect the general diabetic population. OBJECTIVE: The purpose of this study is to assess the association between GU infections in patients started on SGLT2is and A1C levels. METHODS: A retrospective study was conducted on patients seen in an adult, primary care clinic, at New York City Health and Hospitals, South Brooklyn Health. Men and nonpregnant, nonlactating women >18 years old with a diagnosis of T2D who were initiated on an SGLT2i between January 2018 and January 2023 were included in the analysis. The primary endpoint is to compare the risk of GU infections in patients with T2D who were started on SGLT2is, regardless of dose, with hemoglobin A1C of >9% to those with hemoglobin A1C <9% at baseline. RESULTS: Three hundred and twenty-eight patients were eligible based on specified inclusion and exclusion criteria. Overall, there was a statistically significant difference in the number of GU infections that occurred in patients with a baseline A1C >9% compared with those with an A1C <9% (95% confidence interval [CI] = 1.05-2.88; P = 0.041). CONCLUSIONS AND RELEVANCE: Type 2 diabetes patients initiated on SGLT2is may experience an increased risk of GU infection, especially in those patients with an A1C of 9% or greater. Further research is necessary to validate and expand upon these findings.

RESUMEN

OPINION STATEMENT: Urothelial carcinoma is the predominant cancer of the urinary tract but when divergent and subtype histology (non-urothelial) are identified at time of pathologic diagnosis, therapeutic and diagnostic challenges transpire. To this end, pathologic review to confirm any non-urothelial histology is key since these subtypes can often be overlooked. Few prospective trials are dedicated to understanding these non-urothelial histologic types; however, current, and past trials did allow patients with these non-urothelial histologic types to enroll, and inferences can be made about treatment efficacy and survival. Existing treatment regimens for non-urothelial bladder cancers are akin to standard urothelial cancer regimens using surgical approaches for localized disease and platinum-based chemotherapy for advanced disease. The reported clinical trials, that will be discussed, center on non-urothelial histologic types. These studies, albeit limited, provide critical insight into tumor biology and response to standard platinum-based chemotherapy, immune checkpoint inhibitors, and antibody drug conjugates. The inclusion of non-urothelial histologic types will be essential for clinical trials in development to provide further therapeutic advances and provide essential efficacy data.

RESUMEN

OPINION STATEMENT: The treatment of oligometastatic genitourinary cancers is a rapidly advancing field with ablative radiotherapy as one of the critical treatment components. The oligometastatic disease state, which can be defined as 1-5 metastatic sites with a controlled primary, represents a distinct clinical state where comprehensive ablative local therapies may provide improved outcomes. Enhanced imaging has increased the number of patients identified with oligometastatic disease. Evidence for improved outcomes with metastasis-directed therapy (MDT) in oligometastatic genitourinary cancers is increasing, and previously published outcome data continues to mature with an increasing body of prospective data to inform the role of MDT in histology-specific settings or in the context of systemic therapy. In select patients, MDT can offer benefits beyond improved local control and allow for time off of systemic therapy, prolonged time until next therapy, or even the hope of cure. However, treatment decisions for locally ablative therapy must be balanced with consideration towards safety. There are exciting advances in technologies to target and adapt treatment in real-time which have expanded options for safer delivery and dose escalation to metastatic targets near critical organs at risk. The role of systemic therapies in conjunction with MDT and incorporation of tumor genetic information to further refine prognostication and treatment decision-making in the oligometastatic setting is actively being investigated. These developments highlight the evolving field of treatment of oligometastatic disease. Future prospective studies combining MDT with enhanced imaging and integrating MDT with evolving systemic therapies will enable the optimal selection of patients most likely to benefit from this "all-or-none" approach and reveal settings in which a combination of therapies could result in synergistic outcomes.

RESUMEN

Background: Sodium‒glucose cotransporter-2 (SGLT2) inhibitors offer glycaemic and cardiorenal benefits in the early stage of chronic kidney disease (CKD). However, the use of SGLT2 inhibitors may increase the risk of genitourinary tract infection (GUTI). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) may also cause deterioration of kidney function. The long-term follow-up of cardiorenal outcomes and GUTI incidence in patients with advanced CKD receiving SGLT2 inhibitors combined with ACEIs/ARBs should be further investigated. Methods: We analysed data from 5,503 patients in Taiwan's Taipei Medical University Research Database (2016-2020) who were part of a pre-end-stage renal disease (ESRD) program (CKD stages 3-5) and received ACEIs/ARBs. SGLT2 inhibitor users were matched 1:4 with nonusers on the basis of sex, CKD, and program entry duration. Results: The final cohort included 205 SGLT2 inhibitor users and 820 nonusers. SGLT2 inhibitor users experienced a significant reduction in ESRD/dialysis risk (aHR = 0.35, 95% CI = 0.190.67), and SGLT2 inhibitor use was not significantly associated with acute kidney injury or acute kidney disease risk. Among SGLT2 inhibitor users, those with a history of cardiovascular disease (CVD) had greater CVD rates. Conversely, those without a CVD history had lower rates of congestive heart failure, arrhythmia, acute pulmonary oedema, and acute myocardial infarction, although the differences were not statistically significant. Notably, SGLT2 inhibitor usage was associated with a greater GUTI incidence (aHR = 1.78, 95% CI = 1.122.84) shortly after initiation, irrespective of prior GUTI history status. Conclusion: Among patients with CKD stages 3-5, SGLT2 inhibitor use was linked to increased GUTI incidence, but it also significantly reduced the ESRD/dialysis risk without an episodic AKI or AKD risk. Clinical physicians should consider a personalized medicine approach by balancing GUTI episodes and cardiorenal outcomes for advanced CKD patients receiving SGLT2 inhibitors.

RESUMEN

INTRODUCTION AND HYPOTHESIS: Genitourinary fistula is a devastating ailment that has an impact on women's physical health, mental health, emotional health, and financial security. The management of genitourinary fistula depends on the type, size, and duration of fistula formation. The purpose of this study is to report the features of genitourinary fistula in Iranian women and our experience in the management of fistula. METHODS: Retrospective chart reviews of 283 patients were performed to determine the cause of the fistula, prior repairs, tissue interposition, and the success rate. The operation was considered successful if the patient did not have any urine leakage during the observation time. RESULTS: The mean (SD) age of women was 49.51 (19.39; range: 21-70) years, Of these, 137 (52.9%) had a history of previous genitourinary fistula surgery. The average fistula was 1.53 (0.041) cm in size. The median (interquartile range) operation lasted 70 (15) min. The success rate after fistula repair was 91.5%. The typical follow-up period lasted 13.26 (range: 1-88) months. Forty-three (15.2%) patients had a big fistula (>2.5 cm) and 4 patients (1.4%) had a history of pelvic radiation therapy, among other reasons for failure. After a second repair, all patients' initial failures were resolved. There were no significant complications, as classified by Clavien-Dindo class 2 or greater. Additionally, there were no bowel, ureteral, or nerve injuries. CONCLUSIONS: Our patients with genitourinary fistula had a successful outcome following repair techniques, without any significant morbidity or mortality.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The genitourinary syndrome of menopause (GSM), apart from symptoms related to vulvovaginal atrophy (VVA), also consists of lower urinary tract symptoms (LUTS). Based on the common embryological origin of the genital and lower urinary system, the presence of estrogen receptors, and the high prevalence of VVA and LUTS in the menopausal population, the two conditions can coexist. This study is aimed at investigating the prevalence and risk factors of LUTS in a sample of Greek peri- and postmenopausal women. METHODS: Four hundred and fifty (450) women, aged 40-70 years, attending three outpatient gynecology clinics for routine examination, completed a structured interview and responded to a validated questionnaire (International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms, ICIQ-FLUTS). RESULTS: Urinary urgency or frequency affected 51.6% and dysuria 43.6% of the participants. Mild urgency or frequency was described by 25.6%, moderate by 14.4%, and severe by 11.6% of the women. Mild dysuria was reported by 26.26%, moderate by 5.8%, and severe by 11.6%. Age, weight, BMI, and number of pregnancies and abortions correlated with a higher ICIQ-FLUTS score. Women with moderate/severe symptoms of VVA, such as irritation, a burning sensation, and pruritus of the vulva or vagina, had a higher ICIQ-FLUTS score than women without such symptoms (beta coefficient 2.42, CI 1.204, 3.635, p < 0.001). CONCLUSIONS: Lower urinary tract symptoms are very common among peri- and postmenopausal women and are linked to symptoms of VVA. Our data support the need for prompt evaluation of women transitioning to menopause, as these symptoms compromise the quality of life.
