RESUMEN

OBJECTIVE: To develop performance metrics that objectively define a reference approach to a transurethral resection of bladder tumours (TURBT) procedure, seek consensus on the performance metrics from a group of international experts. METHODS: The characterisation of a reference approach to a TURBT procedure was performed by identifying phases and explicitly defined procedure events (i.e., steps, errors, and critical errors). An international panel of experienced urologists (i.e., Delphi panel) was then assembled to scrutinise the metrics using a modified Delphi process. Based on the panel's feedback, the proposed metrics could be edited, supplemented, or deleted. A voting process was conducted to establish the consensus level on the metrics. Consensus was defined as the panel majority (i.e., >80%) agreeing that the metric definitions were accurate and acceptable. The number of metric units before and after the Delphi meeting were presented. RESULTS: A core metrics group (i.e., characterisation group) deconstructed the TURBT procedure. The reference case was identified as an elective TURBT on a male patient, diagnosed after full diagnostic evaluation with three or fewer bladder tumours of ≤3 cm. The characterisation group identified six procedure phases, 60 procedure steps, 43 errors, and 40 critical errors. The metrics were presented to the Delphi panel which included 15 experts from six countries. After the Delphi, six procedure phases, 63 procedure steps, 47 errors, and 41 critical errors were identified. The Delphi panel achieved a 100% consensus. CONCLUSION: Performance metrics to characterise a reference approach to TURBT were developed and an international panel of experts reached 100% consensus on them. This consensus supports their face and content validity. The metrics can now be used for a proficiency-based progression training curriculum for TURBT.

RESUMEN

PURPOSE OF THE REVIEW: Genital mutilation in males can range from minor injuries (cuts from a blade) to severe urological emergencies (testicular or penile amputation). Due to the rarity of these events, there is a lack of extensive reports, as most of the available literature is regarding single cases. Genital mutilation has been associated with psychotic and non-psychotic causes, psychiatric conditions, drug consumption, sexual practices, or even cultural or religious beliefs. It is crucial to perform a psychiatric evaluation of these patients to obtain the best therapeutic approach. This manuscript serves as a review of the currently available knowledge regarding male genital mutilation. RECENT FINDINGS: A great variety of reasons have been associated with genital mutilation. Previous authors have distinguished between those that present with a clear mental health precursor from cases with no psychotic background. Nevertheless, sometimes, it is difficult to make this distinction. Recently, reconstructive techniques for amputation cases have moved towards a microsurgical approach in order to improve outcomes. A holistic therapeutic approach must be performed to increase the chances of effective treatment. Close collaboration between urologists, psychiatrists, and emergency doctors is essential to ensure the best care for patients performing genital mutilation. Future publications must evaluate differences in treatment options and the impact that these have on the long-term well-being of patients undergoing genital self-mutilation.

RESUMEN

Rectourethral fistula (RUF) is an infrequent but severe complication of the treatment of prostate cancer. Herein, we describe a new surgical approach used successfully in 3 patients that incorporates a partially de-epithelialized mid-perineal scrotal flap (MPSF), used as interposition flap, that can be used in almost every patient with RUF after radiotherapy, regardless of having or not a concomitant posterior urethra or bladder neck stricture or contracture that might require a simultaneous urethroplasty. The interposition flap includes well vascularized subcutaneous fat tissue by distal vascular branches of the internal pudendal vessels that reaches without tension the deep perineum up to the posterior bladder neck. The MPSF is a time efficient procedure that allows excellent access to the bulbar urethra and to the surgical plane between rectum and prostate and it does not require a separate incision for the flap harvesting procedure when required.

RESUMEN

Chlamydia trachomatis infection is an important public health problem. Our objective was to assess the dynamics of the transmission of this infection, analysing the distribution of circulating ompA genotypes and multilocus sequence types of C. trachomatis in Spain as a function of clinical and epidemiological variables. During 2018 and 2019, we genetically characterized C. trachomatis in tertiary hospitals in six areas in Spain (Asturias, Barcelona, Gipuzkoa, Mallorca, Seville and Zaragoza), with a catchment population of 3.050 million people. Genotypes and sequence types were obtained using polymerase chain reaction techniques that amplify a fragment of the ompA gene, and five highly variable genes (hctB, CT058, CT144, CT172 and pbpB), respectively. Amplicons were sequenced and phylogenetic analysis was conducted. We obtained genotypes in 636/698 cases (91.1%). Overall and by area, genotype E was the most common (35%). Stratifying by sex, genotypes D and G were more common among men, and genotypes F and I among women (p < 0.05). Genotypes D, G and J were more common in men who have sex with men (MSM) than in men who have sex with women (MSW), in whom the most common genotypes were E and F. The diversity index was higher in sequence typing (0.981) than in genotyping (0.791), and the most common sequence types were ST52 and ST108 in MSM, and ST30, ST148, ST276 and ST327 in MSW. Differences in genotype distribution between geographical areas were attributable to differences in population characteristics. The transmission dynamics varied with sexual behaviour: the predominant genotypes and most frequent sequence types found in MSM were different to those detected in MSW and women.

RESUMEN

Von Hippel-Lindau (VHL) syndrome is a rare inherited cancer disease where the lack of VHL protein triggers the development of multisystemic tumors such us retinal hemangioblastomas (HBs), CNS-HBs, and clear cell renal cell carcinoma (ccRCC). Since standard therapies in VHL have shown limited response, leaving surgery as the only possible treatment, targeting of the ß2-adrenergic receptor (ADRB2) has shown therapeutic antitumor benefits on VHL-retinal HBs (clinical trial), VHL-CNS HBs, and VHL-ccRCC (in vitro and in vivo). In the present study, we wanted to look deep into the effects of the ADRB2 blockers propranolol and ICI-118,551 on two main aspects of cancer progression: (i) the changes on the inflammatory response of ccRCC cells; and (ii) the modulation on the Warburg effect (glycolytic metabolism), concretely, on the expression of genes involved in the cell reactive oxygen species (ROS) balance and levels. Accordingly, in vitro studies with primary VHL-ccRCC and 786-O cells measuring ROS levels, ROS-expression of detoxifying enzymes, and the expression of p65/NF-κB targets by RT-PCR were carried out. Furthermore, histological analyses of ccRCC samples from heterotopic mouse xenografts were performed. The obtained results show that ADRB2 blockade in ccRCC cells reduces the level of oxidative stress and stabilizes the inflammatory response. Thus, these data further support the idea of targeting ADRB2 as a promising strategy for the treatment of VHL and other non-VHL tumors.

RESUMEN

Patients with relapsed or refractory multiple myeloma (RRMM) have limited treatment options and poor survival outcomes. The increasing adoption of lenalidomide-based therapy for frontline treatment of multiple myeloma has resulted in a need for effective regimens for lenalidomide-refractory patients. This phase 1b study evaluated daratumumab plus carfilzomib and dexamethasone (D-Kd) in patients with RRMM after 1 to 3 prior lines of therapy, including bortezomib and an immunomodulatory drug; lenalidomide-refractory patients were eligible. Carfilzomib- and daratumumab-naïve patients (n = 85) received carfilzomib weekly on days 1, 8, and 15 of each 28-day cycle (20 mg/m2 initial dose, escalated to 70 mg/m2 thereafter) and dexamethasone (40 mg/wk). Of these, 10 patients received the first daratumumab dose as a single infusion (16 mg/kg, day 1 cycle 1), and 75 patients received a split first dose (8 mg/kg, days 1-2 cycle 1). Subsequent dosing was per the approved schedule for daratumumab. Patients received a median of 2 (range, 1-4) prior lines of therapy; 60% were lenalidomide refractory. The most common grade 3/4 treatment-emergent adverse events were thrombocytopenia (31%), lymphopenia (24%), anemia (21%), and neutropenia (21%). Infusion-related reactions were observed in 60% and 43% of single and split first-dose patients, respectively. Overall response rate was 84% (79% in lenalidomide-refractory patients). Median progression-free survival (PFS) was not reached; 12-month PFS rates were 74% for all treated patients and 65% for lenalidomide-refractory patients. D-Kd was well tolerated with low neutropenia rates, and it demonstrated deep responses and encouraging PFS, including in patients refractory to lenalidomide. The trial was registered at www.clinicaltrials.gov as #NCT01998971.

RESUMEN

BACKGROUND: To use the European Association of Urology Research Foundation (EAURF) registry data to determine the proportion of contemporary Lower Urinary Tract Symptoms associated with Benign Prostatic Enlargement (LUTS/BPE) patients prescribed phytotherapy, and to determine their subjective quality of life and clinical progression responses. METHODS: This was a prospective multicenter multinational observational registry study, conducted over 2 years. Men ≥ 50 years seeking LUTS/BPE were divided at baseline into two cohorts, presently/recently untreated patients (PUP) commencing pharmacotherapy at baseline and presently/recently treated patients (c-PTP) continuing previously received pharmacotherapy, with 24-month follow-up (FU). RESULTS: Overall, 2175 patients were enrolled with 1838 analyzed. Of the PUP cohort (n = 575), 92 (16%) received phytotherapy and 65 (71%, n = 65/92) completed 24-month FU, with France prescribing 34% (n = 30/89) the highest proportion of phytotherapy among all LUTS/BPE medications. In the c-PTP group (n = 1263), only 69 (5%) patients were using phytotherapy, falling to n = 35/69 (51%) at 24-month FU (highest in France 20% (n = 43/210)). Though defined disease progression occurred in ≤ 20%, with only 1% proceeding to surgical intervention, in both groups, clinically meaningful improvement was lower and symptom persistence was higher in PUP but similar in the treated (c-PTP) patients on phytotherapy compared to the other LUTS/BPE medication. CONCLUSION: Low heterogeneous prescribing rates for phytotherapy were reported in both PUP and c-PTP cohorts over the 24-month FU. Although phytotherapy led to subjective improvements, healthcare practitioners should prescribe them with caution until higher quality evidence and guideline recommendations supporting its use are available.

RESUMEN

PURPOSE: To assess the impact of perioperative chemotherapy on survival in cN+ BCa patients and analyze it according to the pN status. METHODS: A retrospective analysis was conducted on 639 BCa patients with cTanyN1-3M0 BCa treated with radical cystectomy (RC) and bilateral lymph node dissection (LND) with or without perioperative chemotherapy in ten tertiary referral centers from 1990 to 2017. Selected cN+ patients received induction chemotherapy (IC), whereas adjuvant chemotherapy (ACT) was delivered to selected pN+ patients. Univariable and multivariable Cox regression analyses were used to predict overall mortality (OM) after surgery, adjusting for clinicopathological confounders. Kaplan-Meier analyses assessed OM according to the treatment modality. RESULTS: Overall, 356 (56%) patients were treated with surgery alone, 155 (24%) with IC followed by surgery, and 128 (20%) with ACT following surgery. Over a median follow-up of 25 months, 316 deaths were recorded. At univariable analysis, patients treated with IC and surgery had lower OM both considering cN+ [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.49-0.87, p = 0.004] and cN+pN- patients (HR 0.61, 95% CI 0.37-0.99, p = 0.05) compared to those treated with surgery alone. cN+pN+ patients treated with ACT experienced lower OM compared to those treated with IC or surgery alone at multivariable analysis (HR 0.40, 95% CI 0.22-0.74, p = 0.003). CONCLUSION: Patients with cTany cN+ cM0 BCa benefit more in terms of OS when treated with IC followed by RC + LND compared to RC + LND alone, regardless of LNMs at final histopathology examination. More data are needed to assess the role of ACT in the management of cN+ patients.

RESUMEN

This paper studies the problem of the dynamic scaling and load balancing of transparent virtualized network functions (VNFs). It analyzes different particularities of this problem, such as loop avoidance when performing scaling-out actions, and bidirectional flow affinity. To address this problem, a software-defined networking (SDN)-based solution is implemented consisting of two SDN controllers and two OpenFlow switches (OFSs). In this approach, the SDN controllers run the solution logic (i.e., monitoring, scaling, and load-balancing modules). According to the SDN controllers instructions, the OFSs are responsible for redirecting traffic to and from the VNF clusters (i.e., load-balancing strategy). Several experiments were conducted to validate the feasibility of this proposed solution on a real testbed. Through connectivity tests, not only could end-to-end (E2E) traffic be successfully achieved through the VNF cluster, but the bidirectional flow affinity strategy was also found to perform well because it could simultaneously create flow rules in both switches. Moreover, the selected CPU-based load-balancing method guaranteed an average imbalance below 10% while ensuring that new incoming traffic was redirected to the least loaded instance without requiring packet modification. Additionally, the designed monitoring function was able to detect failures in the set of active members in near real-time and active new instances in less than a minute. Likewise, the proposed auto-scaling module had a quick response to traffic changes. Our solution showed that the use of SDN controllers along with OFS provides great flexibility to implement different load-balancing, scaling, and monitoring strategies.

RESUMEN

Castleman's disease (CD) is an uncommon type of lymphoproliferative disorder. Its etiology and prevalence are unclear. The retroperitoneum is a very rare site for presentation of the unicentric variant, where it mimics malignant tumors. A 59-year-old man is referred to the urology outpatient clinic for the study of microhematuria found in a routine analysis. CT scan of the abdomen identified a solid, circumscribed mass, measuring 28 × 30 × 31 mm in the left para-aortic zone, with homogeneous contrast enhancement. Excisional surgery and regional lymphadenectomy were performed via laparoscopy. Postoperative course concurred without incidences. Histological diagnosis confirmed unicentric CD, hyaline-vascular type. CD is a rare entity, and the unicentric type presents as an asymptomatic mass. Retroperitoneum is a rare localization, where initial imaging diagnosis is unclear and surgical resection is the preferred treatment.

RESUMEN

OBJECTIVES: To assess time to progression to castrate-resistant prostate cancer (CRPC) and factors influencing longer-term outcomes in patients receiving androgen-deprivation therapy (ADT) in an extension to the Triptocare study (NCT01020448). This is pertinent as the Triptocare study did not show that urinary prostate cancer antigen-3 (PCA3) score was a reliable marker of cancer stage in advanced prostate cancer and was not useful for assessing response 6 months after initiation of ADT with triptorelin 22.5 mg. PATIENTS AND METHODS: An international, multicentre, non-interventional, observational, longitudinal, prospective study involving patients from the Triptocare study. CRPC status of patients was collected for up to 3 years from ADT initiation. Patient treatment and assessments were at the investigator's discretion. Co-primary endpoints were rate of CRPC at 3 years after initiating ADT and the median time to CRPC. An exploratory endpoint was the association of Triptocare baseline variables (including TMPRSS2-ERG and PCA3 scores) and PCA3 score at Triptocare last value available with CRPC onset. RESULTS: Of the 325 patients in the Triptocare study safety population, 180 patients were enrolled in the Triptocare LT study (102 received continuous and 78 received intermittent ADT). CRPC rates at 3 years were 24/102 (23.5%) and 6/78 (7.7%) patients in the continuous and intermittent ADT groups, respectively. The median time to CRPC was not reached for either group. PCA3 score status at baseline was the only variable associated with a higher risk of progression to CRPC in both the intermittent and continuous ADT groups; compared with a baseline PCA3 score of ≥35, a PCA3 score below the level of quantification had a hazard ratio (HR) of 20.04 ([95% confidence interval (CI) 2.71-148.34] and a HR of 9.44 [95% CI 2.39-37.27], respectively). Baseline metastatic disease and testosterone level were additionally associated with progression to CRPC in the continuous ADT population (HR 5.20, 95% CI 1.68-16.06 and HR 0.995, 95% CI 0.991-0.999, respectively). CONCLUSION: In men with locally advanced or metastatic prostate cancer, a PCA3 score of ≥35 at the time of initiating ADT may predict a lower risk of developing CRPC in the following 3 years.

RESUMEN

PURPOSE: To describe the perioperative and oncology outcomes in a series of laparoscopic or robotic partial nephrectomies (PN) for renal tumors treated in diverse institutions of Hispanic America from the beginning of their minimally invasive (MI) PN experience through December 2014. METHODS: Seventeen institutions participated in the CAU generated a MI PN database. We estimated proportions, medians, 95 % confidence intervals, Kaplan-Meier curves, multivariate logistic and Cox regression analyses. Clavien-Dindo classification was used. RESULTS: We evaluated 1501 laparoscopic (98 %) or robotic (2 %) PNs. Median age: 58 years. Median surgical time, warm ischemia and intraoperative bleeding were 150, 20 min and 200 cc. 81 % of the lesions were malignant, with clear cell histology being 65 % of the total. Median maximum tumor diameter is 2.7 cm, positive margin is 8.2 %, and median hospitalization is 3 days. One or more postoperative complication was recorded in 19.8 % of the patients: Clavien 1: 5.6 %; Clavien 2: 8.4 %; Clavien 3A: 1.5 %; Clavien 3B: 3.2 %; Clavien 4A: 1 %; Clavien 4B: 0.1 %; Clavien 5: 0 %. Bleeding was the main cause of a reoperation (5.5 %), conversion to radical nephrectomy (3 %) or open partial nephrectomy (6 %). Transfusion rate is 10 %. In multivariate analysis, RENAL nephrometry score was the only variable associated with complications (OR 1.1; 95 % CI 1.02-1.2; p = 0.02). Nineteen patients presented disease progression or died of disease in a median follow-up of 1.37 years. The 5-year progression or kidney cancer mortality-free rate was 94 % (95 % CI 90, 97). Positive margins (HR 4.98; 95 % CI 1.3-19; p = 0.02) and females (HR 5.6; 95 % CI 1.7-19; p = 0.005) were associated with disease progression or kidney cancer mortality after adjusting for maximum tumor diameter. CONCLUSION: Laparoscopic PN in these centers of Hispanic America seem to have acceptable perioperative complications and short-term oncologic outcomes.

RESUMEN

OBJECTIVE: To assess prostate cancer antigen-3 (PCA3) and TMPRSS2-ERG scores in patients with advanced and metastatic prostate cancer at baseline and after 6 months of treatment with triptorelin 22.5 mg, and analyse these scores in patient-groups defined by different disease characteristics. PATIENTS AND METHODS: The Triptocare study was a prospective, open-label, multicentre, single-arm, Phase III study of triptorelin 22.5 mg in men with locally advanced or metastatic prostate cancer, who were naïve to androgen-deprivation therapy (ADT). The primary objective was to model the urinary PCA3 change at 6 months, according to baseline variables. Other outcome measures included urinary PCA3 and TMPRSS2-ERG scores and statuses, and serum testosterone and prostate-specific antigen (PSA) levels at baseline and at 1, 3 and 6 months after initiation of ADT. Safety was assessed by recording adverse events and changes in laboratory parameters. RESULTS: The intent-to-treat population comprised 322 patients; 39 (12.1%) had non-assessable PCA3 scores at baseline, and 109/322 (33.9%), 215/313 (68.7%) and 232/298 (77.9%) had non-assessable PCA3 scores at 1, 3 and 6 months, respectively. Baseline Gleason score was the only variable associated with non-assessability of PCA3 score at 6 months (P = 0.017) - the hazard of having a non-assessable PCA3 score at 6 months was 1.824-fold higher (95% confidence interval 1.186-2.805) in patients with a Gleason score ≥8 vs those with a Gleason score ≤6. The median PCA3 scores at baseline were significantly higher in patients aged ≥65 years vs those aged <65 years and in patients with a serum PSA level <100 ng/mL vs those with serum PSA level of >200 ng/mL. The median PCA3 score was significantly lower in patients with metastasis than in patients with no metastasis or unknown metastasis status. TMPRSS2-ERG scores ≥35 were considered positive (n = 149 [51.6%]). Age, presence of metastasis, PSA level and Gleason score at baseline were not associated with a significant difference in the proportion of TMPRSS2-ERG-positive scores. The median serum PSA levels decreased from 45.5 ng/mL at baseline to 1.2 ng/mL after 6 months, and as expected, >90% of patients achieved castrate levels of testosterone (<50 ng/dL) at 1, 3, and 6 months during triptorelin treatment. The safety profile reported from this study is consistent with the known safety profile of triptorelin. CONCLUSION: These data from the Triptocare study suggest that urinary PCA3 or TMPRSS2-ERG score are not reliable markers of cancer stage in advanced prostate cancer. Urinary PCA3 and TMPRSS2-ERG scores do not appear to be useful in assessing response to ADT in advanced prostate cancer, with most patients having non-assessable scores after 6 months of treatment.

RESUMEN

Posterior urethral injuries typically arise in the context of a pelvic fracture.The correct and appropriate initial treatment of associated urethral rupture is critical to the proper healing of the injury. In this paper, we provide a comprehensive review of the literature with special emphasis on the various treatments available: open or endoscopic primary realignment, immediate or delayed urethroplasty after suprapubic cystostomy, and delayed optical urethrotomy.

RESUMEN

The short-lived nature and heterogeneity of Natural Killer (NK) cells limit the development of NK cell-based therapies, despite their proven safety and efficacy against cancer. Here, we describe the biological basis, detailed phenotype and function of long-lived anti-tumour human NK cells (CD56highCD16+), obtained without cell sorting or feeder cells, after priming of peripheral blood cells with Bacillus Calmette-Guérin (BCG). Further, we demonstrate that survival doses of a cytokine combination, excluding IL18, administered just weekly to BCG-primed NK cells avoids innate lymphocyte exhaustion and leads to specific long-term proliferation of innate cells that exert potent cytotoxic function against a broad range of solid tumours, mainly through NKG2D. Strikingly, a NKG2C+CD57-FcεRIγ+ NK cell population expands after BCG and cytokine stimulation, independently of HCMV serology. This strategy was exploited to rescue anti-tumour NK cells even from the suppressor environment of cancer patients' bone marrow, demonstrating that BCG confers durable anti-tumour features to NK cells.

RESUMEN

OBJECTIVES: Laparoscopic radical nephrectomy is considered to be the technique of choice in the management of stage T1 and T2 renal cancer, through increased expertise in this alternative type of surgery has served to expand its indications. In any case, these procedures have a series of limitations which are tied to the intrinsic characteristics of laparoscopic surgery, and associated with patient and tumor characteristics, and surgeon's expertise. METHODS: We performed a bibliographic review through Pub Med database. RESULTS: The present study discusses the different indications and establishes the current limits of laparoscopic surgery applied to the management of renal tumors (including T3 and T4). Its role in cell reducing therapy for metastatic disease, and the available methods to reduce tumor implantation in the surgical ports are also commented. CONCLUSIONS: Radical laparoscopic surgery is the technique of choice for the treatment of renal tumors in stage T1 and T2. There are not significant differences among the different approaches, and it has lower incision-related morbidity compared to traditional surgery, a shorter period of convalescence and the same oncological efficacy.

RESUMEN

OBJECTIVES: Testosterone deficit syndrome (TDS)is a clinical and biochemical entity characterized by low testosterone levels and androgenic deprivation clinic, which can cause a decrease in the quality of life. However, today there are doubts about its diagnosis and therapeutic management. METHODS: Bibliographic review using the MedLine database and detailed presentation of one clinical case. RESULTS: Testosterone deficit syndrome is associated with metabolic syndrome (visceral obesity, arterial hypertension, diabetes mellitus and dyslipemia). Currently, the performance of TDS screening in all males over the age of 45 years is under discussion. We propose a diagnostic-therapeutic algorithm for the management of TDS and erectile dysfunction. CONCLUSIONS: The treatment of erectile dysfunction associated with late start hypogonadism follows the same steps tha other generic cases of erectile dysfunction.

RESUMEN

The aim of this multicentre project (seven hospitals across the Spanish National Health Service) was to study the phenotypic and genotypic susceptibility of C. trachomatis to the main antimicrobials used (macrolides, doxycycline, and quinolones) in isolates from patients with clinical treatment failure in whom reinfection had been ruled out. During 2018-2019, 73 clinical isolates were selected. Sixty-nine clinical specimens were inoculated onto confluent McCoy cell monolayers for phenotypic susceptibility testing. The minimum inhibitory concentration for azithromycin and doxycycline was defined as the lowest concentration associated with an at least 95% reduction in inclusion-forming units after one passage in the presence of the antibiotic compared to the initial inoculum for each strain (control). Sequencing analysis was performed for the genotypic detection of resistance to macrolides, analysing mutations in the 23S rRNA gene (at positions 2057, 2058, 2059, and 2611), and quinolones, analysing a fragment of the gyrA gene, and searching for the G248T mutation (Ser83->Ile). For tetracyclines, in-house RT-PCR was used to test for the tet(C) gene. The phenotypic susceptibility testing was successful for 10 isolates. All the isolates had minimum inhibitory concentrations for azithromycin ≤ 0.125 mg/L and for doxycycline ≤ 0.064 mg/L and were considered sensitive. Of the 73 strains studied, no mutations were found at positions T2611C or G248T of the gyrA gene. We successfully sequenced 66 isolates. No macrolide resistance-associated mutations were found at positions 2057, 2058, 2059, or T2611C. None of the isolates carried the tet(C) gene. We found no evidence for genomic resistance in this large, clinically relevant dataset.

RESUMEN

Persistent cytopenia in the post-hematopoietic cell transplantation (HCT) setting can occur despite adequate engraftment of donor cells. PLX-R18, a placental-derived mesenchymal-like cell product, is expanded ex vivo in a 3-dimensional environment. PLX-R18 cells secrete a large array of hematopoietic factors, which promote regeneration, maturation, and differentiation of hematopoietic cells and stimulate their migration to peripheral blood. This phase 1, first-in-human study (NCT03002519), included 21 patients with incomplete hematopoietic recovery post-HCT. Patients were treated with escalating doses of PLX-R18: 3 patients received 1 million cells/kg, 6 received 2 million cells/kg, and 12 received 4 million cells/kg via multiple intramuscular injections. While patients received only two administrations of cells during the first week, peripheral blood counts continued to increase for months, peaking at 6 months for hemoglobin (Hb, p = 0.002), lymphocytes (p = 0.008), and neutrophils (ANC, p = 0.063), and at 9 months for platelets (p < 0.001) and was maintained until 12 months for all but ANC. The need for platelet transfusions was reduced from 5.09 units/month at baseline to 0.55 at month 12 (p = 0.05). Likewise, red blood cell transfusions decreased from 2.91 units/month at baseline to 0 at month 12 (p = 0.0005). PLX-R18 was safe and well tolerated and shows promise in improving incomplete hematopoietic recovery post-HCT.

RESUMEN

Background: Adverse events induced by intravesical bacillus Calmette-Guérin (BCG) to treat high-grade non-muscle-invasive bladder cancer (NMIBC) often lead to treatment discontinuation. The EAU-RF NIMBUS trial found a reduced number of standard-dose BCG instillations to be inferior with the standard regimen. Nonetheless, it remains important to evaluate whether patients in the reduced BCG treatment arm had better quality of life (QoL) due to a possible reduction in toxicity or burden. Objective: To evaluate whether patients in the EAU-RF NIMBUS trial experienced better QoL after a reduced BCG instillation frequency. Design setting and participants: A total of 359 patients from 51 European sites were randomized to one of two treatment arms between December 2013 and July 2019. The standard frequency arm (n = 182) was 6 weeks of BCG induction followed by 3 weeks of maintenance at months 3, 6, and 12. The reduced frequency arm (n = 177) was BCG induction at weeks 1, 2, and 6, followed by maintenance instillations at weeks 1 and 3 of months 3, 6, and 12. Outcome measurements and statistical analysis: Analyses were performed using an intention-to-treat analysis and a per-protocol analysis. QoL was measured using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 version 3.0 (QLQ-C30 v.03) prior to the first and last instillations of each BCG cycle. Group differences were determined using linear regression corrected for QoL at baseline. Differences in QoL over time were tested for significance using a linear mixed model. Side effects were recorded by the treating physician using a standardized form. Chi-square tests were used to compare the side-effect frequency between the arms. Results and limitations: There were no significant differences in the means of each QoL scale between the two arms. There were also no significant changes over time in all QoL domains for both arms. However, differences in the incidence of general malaise at T1 (before the last induction instillation), frequency, urgency, and dysuria at T7 (before the last maintenance instillation) were detected in favor of the reduced frequency arm. Conclusions: Reducing the BCG instillation frequency does not improve the QoL in NMIBC patients despite lower storage symptoms. Patient summary: In this study, we evaluated whether a reduction in the number of received bacillus Calmette-Guérin instillations led to better quality of life in patients with high-grade non-muscle-invasive bladder cancer. We found no difference in the quality of life between the standard and the reduced bacillus Calmette-Guérin instillation frequency. We conclude that reducing the number of instillations does not lead to better quality of life in patients with high-grade non-muscle-invasive bladder cancer.
