RESUMEN

BACKGROUND: Poor comprehension of prostate cancer (PCa) medical terms can create barriers to PCa treatment discussions. The authors measured comprehension of PCa terms and its relationship to health literacy in a group of Black men who were newly diagnosed with PCa. They examined whether tailoring communication with alternative colloquial words would be helpful and acceptable. METHODS: Patients were recruited from urology clinics (N = 152). After they met with their providers to discuss PCa treatment options, they participated in an educational supplement delivered as a structured interview. The supplement tailored PCa treatment information by allowing men to choose between colloquial and medical terms for genitourinary (GU) function. Health literacy was measured using the Rapid Estimate of Adult Literacy in Medicine, and comprehension of common PCa terms was assessed using published methods. Pearson correlation was used to estimate the association between health literacy and comprehension of PCa terms. Spearman rank correlation (r) was used to assess the relation between the total number of medical terms preferred (range, 0-10) and Rapid Estimate of Adult Literacy in Medicine scores (range, 0-66). RESULTS: Most patients (62%) had low health literacy, which was strongly correlated with their understanding of PCa terms (r = 0.526; p < .001). Poor comprehension of many PCa terms established the need to use alternative language for GU function (only 20% knew the word incontinence). There was a statistically significant positive association between the number of medical terms preferred and health literacy (r = 0.358; p < .001). A majority of patients (91%) preferred a mixture of medical and colloquial terms. CONCLUSIONS: Tailoring communications with colloquial terms for GU function was preferred by most patients regardless of health literacy.

RESUMEN

INTRODUCTION: The prevalence of preoperative paraneoplastic syndromes (PNS) in renal cell carcinoma (RCC) is poorly understood. Many laboratory abnormalities representative of PNS have demonstrated prognostic value when incorporated into predictive survival models in RCC. We sought to characterize the relationship between baseline prevalence of PNS with overall survival (OS) and cancer-specific survival (CSS) in RCC patients following nephrectomy. METHODS: Our prospectively maintained nephrectomy database was retrospectively reviewed for any stage, major histology RCC patients that underwent surgery from 2000 to 2022. Baseline laboratory values within 90 days (closest used) were required. Presence of PNS was defined according to established laboratory cutoffs. Kaplan-Meier curves estimated survival rates, and multivariable Cox proportional hazards models examined the association between PNS with OS and CSS following nephrectomy. RESULTS: 2599 patients were included with listed staging: 1494 Stage I; 180 Stage II; 616 Stage III; 306 Stage IV. Proportion of patients presenting with >1 PNS significantly increased from stage I (31.3%) to stage IV (74.2%) RCC (P < .001). Elevated C-reactive protein was the most prevalent PNS (45.4%). On multivariable analysis, the presence of >1 PNS was associated with higher risk of all-cause (HR 2.09; P < .001) and cancer-specific mortality (HR 2.55; P < .001). The 10-year OS estimates as reported: 65.2% (no PNS), 52.3% (1 PNS), 36.6% (>1 PNS); and 10-year CSS estimates: 88.3% (no PNS), 79.3% (1 PNS), 61.6% (>1 PNS). DISCUSSION: Increased prevalence of PNS in major histology RCC was associated with a significant increase in the risk of all-cause and cancer-specific mortality even when accounting for patient and disease characteristics.

RESUMEN

Cabozantinib is an oral multikinase inhibitor approved for treatment in metastatic renal cell carcinoma (RCC). We hypothesized that neoadjuvant cabozantinib could downstage localized tumors, facilitating partial nephrectomy, and facilitating surgery in patients with locally advanced tumors that would require significant adjacent organ resection. We, therefore, conducted a phase 2, single-arm trial of cabozantinib treatment for 12 weeks in 17 patients with locally advanced biopsy-proven non-metastatic clear cell RCC before surgical resection. Six patients (35%) experienced a partial response, and 11 patients (65%) had stable disease. We identified that plasma cell-free DNA (cfDNA), VEGF, c-MET, Gas6, and AXL were significantly increased while VEGFR2 decreased during cabozantinib treatments. There was a trend towards CD8+ T cells becoming activated in the blood, expressing the proliferation marker Ki67 and activation markers HLA-DR and CD38. Cabozantinib treatment depleted myeloid populations acutely. Importantly, immune niches made up of the stem-like CD8+ T cells and antigen presenting cells were increased in every patient. These data suggest that cabozantinib treatment was clinically active and safe in the neoadjuvant setting in patients with locally advanced non-metastatic clear cell RCC and activated the anti-tumor CD8+ T cell response. The trial is registered at ClinicalTrials.gov under registration no. NCT04022343.

RESUMEN

BACKGROUND: Bladder cancer with divergent differentiation (BCDD) comprises a heterogenous group of tumors with a poor prognosis, and differential expression of nectin-4 and programmed death ligand-1 (PD-L1) has been reported in BCDD. Importantly, nectin-4 expression in bladder cancer is associated with response to enfortumab vedotin, and PD-L1 expression is associated with responses to immune checkpoint inhibitors (ICIs). METHODS: The authors conducted a retrospective review identifying 117 patients with advanced or metastatic BCDD who were treated at Winship Cancer Institute from 2011 to 2021. They performed immunohistochemistry staining for nectin-4 and PD-L1 expression by histologic subtype as well as genomic analysis of these patients, including RNA sequencing, whole-exome sequencing, and fusion detection analysis as well as a subgroup genomic analysis of patients with BCDD who received ICIs. RESULTS: The results indicated that nectin-4 expression was highest in the groups who had the squamous and plasmacytoid subtypes, whereas the group that had the sarcomatoid subtype (70.8%) had the highest proportion of PD-L1-positive patients. Genomic analysis yielded several key findings, including a 50% RB1 mutation rate in patients who had small cell BCDD, targetable PIK3CA mutations across multiple subtypes of BCDD, and significantly higher expression of TEC in responders to ICIs. CONCLUSIONS: In this study, the authors identified clinically relevant data on nectin-4 and PD-L1 expression in patients with rare bladder tumors. They also identified several novel findings in the genomic analysis that highlight the role of precision medicine in this population of patients. Larger, prospective studies are needed to validate these hypothesis-generating data.

RESUMEN

PURPOSE: Nadofaragene firadenovec-vncg is a nonreplicating adenoviral vector-based gene therapy for bacillus Calmette-Guérin (BCG)-unresponsive carcinoma in situ (CIS) with/without high-grade Ta/T1. We report outcomes following 5 years of planned follow-up. MATERIALS AND METHODS: This open-label phase 3 trial (NCT02773849) enrolled patients with BCG-unresponsive nonmuscle-invasive bladder cancer in 2 cohorts: CIS ± Ta/T1 (CIS; n = 107) and Ta/T1 without CIS (Ta/T1 cohort; n = 50). Patients received 75 mL (3 × 1011 vp/mL) nadofaragene firadenovec intravesically once every 3 months with cystoscopy and cytology assessments, with continued treatment offered to those remaining high grade recurrence-free (HGRF). RESULTS: One hundred fifty-seven patients were enrolled from 33 US sites (n = 151 included in efficacy analyses). Median follow-up was 50.8 months (interquartile range 39.1-60.0), with 27% receiving ≥ 5 instillations and 7.6% receiving treatment for ≥ 57 months. Of patients with CIS 5.8% (95% CI 2.2-12.2) were HGRF at month 57, and 15% (95% CI 6.1-27.8) of patients with high-grade Ta/T1 were HGRF at month 57. Kaplan-Meier-estimated HGRF survival at 57 months was 13% (95% CI 6.9-21.5) and 33% (95% CI 19.5-46.6) in the CIS and Ta/T1 cohorts, respectively. Cystectomy-free survival at month 60 was 49% (95% CI 40.0-57.1): 43% (95% CI 32.2-53.7) in the CIS cohort and 59% (95% CI 43.1-71.4) in the Ta/T1 cohort. Overall survival at 60 months was 80% (71.0, 86.0): 76% (64.6-84.5) and 86% (70.9-93.5) in the CIS and Ta/T1 cohorts, respectively. Only 5 patients (4 with CIS and 1 with Ta/T1) experienced clinical progression to muscle-invasive disease. CONCLUSIONS: At 60 months, nadofaragene firadenovec-vncg allowed bladder preservation in nearly half of the patients and proved to be a safe option for BCG-unresponsive nonmuscle-invasive bladder cancer.

RESUMEN

OBJECTIVES: To assess the effects of immunotherapy compared to chemotherapy as first- and second-line treatment of advanced or metastatic urothelial carcinoma. METHODS: Based on a published protocol, we performed a systematic search of multiple databases. Two review authors independently performed the literature selection, identified relevant studies, assessed the eligibility of studies for inclusion, and extracted data. We performed statistical analyses using a random-effects model and assessed the quality of the evidence on a per-outcome basis according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We included five randomised controlled trials and also identified seven single-arm studies. When used as first-line therapy, immunotherapy probably has little to no effect on the risk of death from any cause compared to chemotherapy (hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.87-1.07; moderate-certainty evidence). immunotherapy probably has little to no effect on health-related quality of life (mean difference [MD] 4.10, 95% CI 3.83-4.37; moderate). Immunotherapy probably reduces grade 3-5 adverse events (risk ratio [RR] 0.47, 95% CI 0.29-0.75; moderate). In the second-line setting immunotherapy may reduce the risk of death from any cause (HR 0.72, 95% CI 0.63-0.81; low). Immunotherapy may have little to no effect on health-related quality of life when compared to chemotherapy (MD 4.82, 95% CI -3.11 to 12.75; low). Immunotherapy may reduce grade 3-5 adverse events (RR 0.89, 95% CI 0.81-0.97; low). CONCLUSIONS: Compared to chemotherapy, immunotherapy has little to no effect on the risk of death from any cause in a first-line setting. Nevertheless, it may reduce the risk of death from any cause when used as second-line therapy. The health-related quality of life of participants receiving first- and second-line therapy does not appear to be affected by immunotherapy. Immunotherapy probably reduces or may reduce grade 3-5 adverse events when used as first- and second-line therapy, respectively.

RESUMEN

Effective bladder-preserving therapeutic options are needed for patients with bacillus Calmette-Guérin unresponsive non-muscle-invasive bladder cancer. Nadofaragene firadenovec-vncg (Adstiladrin®) was approved by the US Food and Drug Administration as the first gene therapy in urology and the first intravesical gene therapy indicated for the treatment of adult patients with high-risk bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ with or without papillary tumors. The proposed mechanism of action underlying nadofaragene firadenovec efficacy is likely due to the pleiotropic nature of interferon-α and its direct and indirect antitumor activities. Direct activities include cell death and the mediation of an antiangiogenic effect, and indirect activities are those initiated through immunomodulation of the innate and adaptive immune responses. The sustained expression of interferon-α that results from this treatment modality contributes to a durable response. This review provides insight into potential mechanisms of action underlying nadofaragene firadenovec efficacy.

RESUMEN

INTRODUCTION: Baseline sarcopenia and postoperative changes in muscle mass are independently associated with overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) undergoing cytoreductive nephrectomy (CN). Here we examine the relationships between preoperative (baseline), postoperative changes in muscle quantity, and survival outcomes following CN as determined by linear segmentation, a clinic-friendly tool that rapidly estimates muscle mass. MATERIALS AND METHODS: Our nephrectomy database was reviewed for patients with metastatic disease who underwent CN for RCC. Linear segmentation of the bilateral psoas/paraspinal muscles was completed for baseline imaging within 60 days of surgery and imaging 30 to 365 days postoperatively. Kruskal-Wallis for numerical and Fisher's exact test for categorical variables were used to test for differences between groups according to percent change in linear muscle index (LMI, cm2/m2). Multivariable Cox proportional hazards models evaluated associations between LMI percent change and cancer-specific (CSM) and all-cause mortality (ACM). Kaplan Meier curves estimated cancer-specific (CSS) and overall survival (OS). RESULTS: From 2004-2020, 205 patients were included of whom 52 demonstrated stable LMI (25.4%; LMI change < 5% [0Δ]), 60 increase (29.3%; LMI +5% [+Δ]), and 92 decrease (44.9%; LMI -5% [-Δ]). Median time from baseline imaging to surgery was 18 days, and time from surgery to postoperative imaging was 133 days. Median CSS and OS were highest among patients with 0Δ LMI (CSS: 133.6 [0Δ] vs. 61.9 [+Δ] vs. 37.4 [-Δ] months; P = .0018 || OS: 67.2 [0Δ] vs. 54.8 [+Δ] vs. 29.5 [-Δ] months; P = .0007). Stable LMI was a protective factor for CSM (HR 0.48; P = .024) and ACM (HR 0.59; P = .040) on multivariable analysis. DISCUSSION: Change in muscle mass after CN, as measured by the linear muscle segmentation technique, is independently associated with OS and CSS in patients following CN. Of note, lack of change was associated with longer survival.

RESUMEN

Scientific knowledge is produced in multiple languages but is predominantly published in English. This practice creates a language barrier to generate and transfer scientific knowledge between communities with diverse linguistic backgrounds, hindering the ability of scholars and communities to address global challenges and achieve diversity and equity in science, technology, engineering and mathematics (STEM). To overcome those barriers, publishers and journals should provide a fair system that supports non-native English speakers and disseminates knowledge across the globe. We surveyed policies of 736 journals in biological sciences to assess their linguistic inclusivity, identify predictors of inclusivity, and propose actions to overcome language barriers in academic publishing. Our assessment revealed a grim landscape where most journals were making minimal efforts to overcome language barriers. The impact factor of journals was negatively associated with adopting a number of inclusive policies whereas ownership by a scientific society tended to have a positive association. Contrary to our expectations, the proportion of both open access articles and editors based in non-English speaking countries did not have a major positive association with the adoption of linguistically inclusive policies. We proposed a set of actions to overcome language barriers in academic publishing, including the renegotiation of power dynamics between publishers and editorial boards.
