Randomized phase 2 dose comparison LITESPARK-013 study of belzutifan in patients with advanced clear cell renal cell carcinoma. Ann Oncol 2024:S0923-7534(24)03918-8. [PMID: 39233312 DOI: 10.1016/j.annonc.2024.08.2338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 07/29/2024] [Accepted: 08/19/2024] [Indexed: 09/06/2024] Open
Abstract
BACKGROUND Belzutifan is a first-in-class HIF-2α inhibitor approved at a dose of 120 mg once daily for certain adults with VHL disease and adults with advanced renal cell carcinoma (RCC) following therapy with a programmed death receptor (or ligand)-1 (PD-[L]1) inhibitor and a vascular endothelial growth factor tyrosine kinase inhibitor. However, whether belzutifan dose could be optimized is unclear. PATIENTS AND METHODS The phase 2 LITESPARK-013 study (NCT04489771) enrolled patients with advanced clear cell RCC whose disease progressed after 1-3 prior systemic therapies, including an anti-PD-(L)1 regimen. Patients were randomly assigned 1:1 to receive belzutifan 120 mg or 200 mg once daily. The primary endpoint was objective response rate (ORR) per RECIST v1.1. Secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS Overall, 154 patients were enrolled (120 mg: n = 76; 200 mg: n = 78). Median follow-up was 20.1 months (range 14.8-28.4). ORR was 23.7% vs 23.1% for the 120 mg and 200 mg groups, respectively (P = 0.5312; -0.5% [95% CI, -14.0 to 12.9]. Median DOR was not reached for the 120 mg arm and was 16.1 months (2.1+ to 23.5+) for the 200 mg arm. No between-group differences were observed for PFS (HR 0.94 [95% CI 0.63-1.40]) or OS (medians not reached; HR 1.11 [95% CI, 0.65-1.90]). Grade 3 or 4 treatment-related adverse events were observed in 35 patients (46.1%) in the 120 mg group and 36 patients (46.2%) in the 200 mg group. CONCLUSION The efficacy of belzutifan was similar between the 120-mg dose and the 200-mg dose for previously treated clear cell RCC. Safety at both doses was consistent with the known safety profile of belzutifan. These results further support 120 mg once daily as the preferred dose for belzutifan.

Elevated middle cerebral artery peak systolic velocity and risk of death in donor twin affected by twin-twin transfusion syndrome but not twin anemia-polycythemia sequence. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2024; 64:222-227. [PMID: 38437460 DOI: 10.1002/uog.27629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 01/29/2024] [Accepted: 02/18/2024] [Indexed: 03/06/2024]
Abstract
OBJECTIVES To determine the association between elevated (> 1.5 multiples of the median (MoM)) middle cerebral artery (MCA) peak systolic velocity (PSV) and fetal demise of the donor twin in pregnancies complicated by twin-twin transfusion syndrome (TTTS) in the absence of twin anemia-polycythemia sequence (TAPS). Secondary objectives were to evaluate if donor or recipient MCA-PSV is associated with a risk for their corresponding fetal death, and to compare the proportion of donor fetuses with low MCA pulsatility index (PI) among donor twins with high MCA-PSV and those with normal MCA-PSV to evaluate the contribution of blood-flow redistribution to the fetal brain in donor twins with high MCA-PSV. METHODS This prospective cohort study included TTTS cases that underwent laser surgery between 2011 and 2022 at a single center. TAPS cases were excluded from the study. Multivariable and Poisson regression analysis were performed to explore the association between isolated elevated donor MCA-PSV and fetal demise, adjusted for TTTS stage, selective fetal growth restriction (sFGR) and other confounders. RESULTS Of 660 TTTS cases, donor MCA-PSV was not recorded in 48 (7.3%) cases. Of the remaining 612 patients, nine (1.5%) were lost to follow-up and 96 TAPS cases were excluded; thus, 507 cases were included in the study. High donor MCA-PSV was seen in 6.5% (33/507) of cases and was an independent risk factor for donor fetal demise (adjusted relative risk (aRR), 4.52 (95% CI, 2.72-7.50)), after adjusting for confounders. Regression analysis restricted to each Quintero TTTS stage demonstrated that high donor MCA-PSV was an independent risk factor for fetal demise of the donor in Quintero Stage II (aRR, 14.21 (95% CI, 1.09-186.2)) and Quintero Stage III (aRR, 3.41 (95% CI, 1.82-6.41)). Donor MCA-PSV in MoM was associated with fetal demise of the donor (area under the receiver-operating-characteristics curve (AUC), 0.69; P < 0.001), but recipient MCA-PSV in MoM was not associated with fetal demise of the recipient (AUC, 0.54; P = 0.44). A higher proportion of donor twins in the group with high MCA-PSV had a low MCA-PI compared to the group with normal MCA-PSV (33.3% vs 15.5%; P = 0.016). CONCLUSIONS Elevated donor MCA-PSV without TAPS prior to laser surgery for TTTS is associated with a 4-fold increased risk for donor fetal demise, adjusted for sFGR, TTTS stage and other confounders. Doppler evaluation of donor MCA-PSV prior to laser surgery may help stratify TTTS staging to evaluate the risk of donor fetal demise. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Prognostic significance of absolute lymphocyte count in patients with metastatic renal cell carcinoma receiving first-line combination immunotherapies: results from the International Metastatic Renal Cell Carcinoma Database Consortium. ESMO Open 2024; 9:103606. [PMID: 38901174 PMCID: PMC11252746 DOI: 10.1016/j.esmoop.2024.103606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 05/18/2024] [Accepted: 05/20/2024] [Indexed: 06/22/2024] Open
Abstract
BACKGROUND Lymphocytes are closely linked to mechanisms of action of immuno-oncology (IO) agents. We aimed to assess the prognostic significance of absolute lymphocyte count (ALC) in patients with metastatic renal cell carcinoma (mRCC). PATIENTS AND METHODS Using the International mRCC Database Consortium (IMDC), patients receiving first-line IO-based combination therapy were analysed. Baseline patient characteristics, objective response rates (ORRs), time to next treatment (TTNT), and overall survival (OS) were compared. RESULTS Of 966 patients included, 195 (20%) had lymphopenia at baseline, and they had a lower ORR (37% versus 45%; P < 0.001), shorter TTNT (10.1 months versus 24.3 months; P < 0.001), and shorter OS (30.4 months versus 48.2 months; P < 0.001). Among 125 patients with lymphopenia at baseline, 52 (42%) experienced ALC recovery at 3 months, and they had longer OS (not reached versus 30.4 months; P = 0.012). On multivariable analysis for OS, lymphopenia was an independent adverse prognostic factor (hazard ratio 1.68; P < 0.001). Incorporation of lymphopenia into the IMDC criteria improved OS prediction accuracy (C-index from 0.688 to 0.707). CONCLUSIONS Lymphopenia was observed in one-fifth of treatment-naive patients with mRCC and may serve as an indicator of unfavourable oncologic outcomes in the contemporary IO era.

Abstract
PURPOSE To assess the severity of glaucoma and its worsening using Spaeth/Richman contrast sensitivity (SPARCS). To evaluate its correlation with retinal nerve fiber layer thickness (RNFL) and perimetry. METHODS In this prospective observational study, 90 eyes of primary open-angle glaucoma were categorized into mild, moderate, and severe glaucoma (30 each). All eyes were subjected to contrast sensitivity measurements by using the Pelli-Robson (PR) chart and SPARCS, Humphrey automated perimetry, and optical coherence tomography (OCT) RNFL, along with routine ophthalmological evaluation at baseline. Contrast sensitivity was repeated at 1, 3, and 6 months. Other investigations were repeated at 6 months. The correlation between contrast sensitivity and other parameters was analyzed at baseline and 6 months. RESULTS Total SPARCS showed a significant positive correlation with visual field index, pattern standard deviation, mean deviation, OCT RNFL, and a negative correlation with best corrected visual acuity. Central SPARCS and PR scores exhibited strong positive correlations. Both total and quadrantic SPARCS significantly reduced from mild to moderate to severe glaucoma. The quadrant-wise SPARCS also correlated well with opposite-side RNFL thickness. At 6 months, SPARCS showed a significant reduction along with RNFL measurements preceding any significant changes in visual field parameters. CONCLUSION This study establishes SPARCS as a reliable and reproducible tool in assessing the deterioration of visual function in glaucoma patients even before significant perimetric changes. The specific relationship of quadrantic SPARCS with opposite-side RNFL is a novel yet expected finding. The findings advocate integrating SPARCS into routine glaucoma assessment for timely detection of any worsening and prompt intervention, improving the visual outcomes in these patients.

A life cycle assessment of transfusion services across England. Transfusion 2024; 64:638-645. [PMID: 38506497 DOI: 10.1111/trf.17786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/02/2024] [Accepted: 03/05/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND Healthcare activities significantly contribute to greenhouse gas (GHG) emissions. Blood transfusions require complex, interlinked processes to collect, manufacture, and supply. Their contribution to healthcare emissions and avenues for mitigation is unknown. STUDY DESIGN AND METHODS We performed a life cycle assessment (LCA) for red blood cell (RBC) transfusions across England where 1.36 million units are transfused annually. We defined the process flow with seven categories: donation, transportation, manufacturing, testing, stockholding, hospital transfusion, and disposal. We used direct measurements, manufacturer data, bioengineering databases, and surveys to assess electrical power usage, embodied carbon in disposable materials and reagents, and direct emissions through transportation, refrigerant leakage, and disposal. RESULTS The central estimate of carbon footprint per unit of RBC transfused was 7.56 kg CO2 equivalent (CO2eq). The largest contribution was from transportation (2.8 kg CO2eq, 36% of total). The second largest was from hospital transfusion processes (1.9 kg CO2eq, 26%), driven mostly by refrigeration. The third largest was donation (1.3 kg CO2eq, 17%) due to the plastic blood packs. Total emissions from RBC transfusion are ~10.3 million kg CO2eq/year. DISCUSSION This is the first study to estimate GHG emissions attributable to RBC transfusion, quantifying the contributions of each stage of the process. Primary areas for mitigation may include electric vehicles for the blood service fleet, improving the energy efficiency of refrigeration, using renewable sources of electricity, changing the plastic of blood packs, and using methods of disposal other than incineration.

Abstract
INTRODUCTION The aims of this systematic review and meta-analysis were to determine if after hip fracture surgery (1) early mobilisation is associated with improved clinical outcomes, and if so (2) are benefits directly proportional to how soon after surgery the patient mobilises. METHODS A Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review was conducted using four databases to identify all studies that compared postoperative early mobilisation with delayed mobilisation, in patients after hip fracture surgery. The Critical Appraisal Skills Programme checklist was employed for critical appraisal and evaluation of all studies that met the inclusion criteria. RESULTS A total of 13 studies, including 297,435 patients were identified, of which 235,275 patients were mobilised early and 62,160 were mobilised late. Six studies assessed 30-day mortality, of which two also investigated 30-day complication rates. Pooled meta-analysis demonstrated that there were significantly lower 30-day mortality rates (odds ratio [OR] 0.35, 95% confidence interval [CI] 0.31-0.41, p < 0.001) and complication rates (OR 0.43, 95% CI 0.36-0.51, p < 0.001) in patients mobilising early after hip fracture surgery. Five studies investigated length of stay (LOS) and meta-analysis revealed no difference between groups (mean difference -0.57 days, 95% CI -1.89-0.74, p = 0.39). CONCLUSION Early mobilisation in hip fracture patients is associated with a reduction in 30-day mortality and complication rates compared to delayed mobilisation, but no difference in LOS. These findings illustrate that early mobilisation is associated with superior post operative outcomes. However, a direct casual effect remains to be demonstrated, and further work on the factors underlying delayed mobilisation is required.

Abstract
The integration of artificial intelligence (AI) in medical image interpretation requires effective collaboration between clinicians and AI algorithms. Although previous studies demonstrated the potential of AI assistance in improving overall clinician performance, the individual impact on clinicians remains unclear. This large-scale study examined the heterogeneous effects of AI assistance on 140 radiologists across 15 chest X-ray diagnostic tasks and identified predictors of these effects. Surprisingly, conventional experience-based factors, such as years of experience, subspecialty and familiarity with AI tools, fail to reliably predict the impact of AI assistance. Additionally, lower-performing radiologists do not consistently benefit more from AI assistance, challenging prevailing assumptions. Instead, we found that the occurrence of AI errors strongly influences treatment outcomes, with inaccurate AI predictions adversely affecting radiologist performance on the aggregate of all pathologies and on half of the individual pathologies investigated. Our findings highlight the importance of personalized approaches to clinician-AI collaboration and the importance of accurate AI models. By understanding the factors that shape the effectiveness of AI assistance, this study provides valuable insights for targeted implementation of AI, enabling maximum benefits for individual clinicians in clinical practice.

Abstract
OBJECTIVES There is a paucity of literature providing evidence-based guidelines for the management of large placental chorioangioma (≥ 4 cm in diameter). The objectives of this study were to compare outcomes between patients managed expectantly and those undergoing in-utero intervention and to describe the different in-utero techniques used for cessation of blood flow to the tumor and the associated outcome. METHODS This was a retrospective cohort study of 34 patients referred for the management of large placental chorioangioma in a single center between January 2011 and December 2022, who were managed expectantly or underwent in-utero intervention. In-utero intervention was performed when the fetus developed any signs of impending compromise, including high combined cardiac output (CCO), worsening polyhydramnios or abnormal fetal Doppler velocimetry findings. Interventions included radiofrequency ablation (RFA), interstitial laser ablation (ILA) and single-port or two-port fetoscopic laser photocoagulation (FLP). Treatment selection was dependent on the proximity of the tumor to the umbilical cord insertion (UCI) and placental location. The two-port technique was performed in patients with a chorioangioma with large feeding vessels (≥ 3 mm) located in the posterior placenta, in which one port was used for occlusion using bipolar forceps and the other port was used for laser photocoagulation of the feeding vessels downstream. The single-port technique was used for chorioangioma with small feeding vessels (< 3 mm) located in the posterior placenta. ILA or RFA was performed in cases with an anterior placenta. Supportive treatments, including amnioreduction and intrauterine transfusion (IUT), were performed for worsening polyhydramnios and suspected fetal anemia based on middle cerebral artery Doppler flow studies, respectively. Comparative statistical analysis between cases undergoing expectant management vs in-utero intervention was performed. Descriptive details were provided for patients who underwent in-utero intervention. RESULTS Thirty-four cases of large chorioangioma were evaluated, of which 25 (73.5%) were managed expectantly and nine (26.5%) underwent intervention. The frequency of polyhydramnios was significantly higher in the intervention group compared with the expectant-management group (66.7% vs 8.0%, P < 0.001). The live-birth rate among expectantly managed cases with large chorioangioma was significantly higher compared with that in cases that underwent in-utero intervention (96.0% vs 62.5%, P = 0.01). In the intervention group, preoperative CCO was elevated in all cases with available information and preoperative hydrops was present in 33.3% (3/9) of cases. One patient experienced fetal demise following IUT prior to planned FLP. Among the remaining eight patients, four underwent two-port FLP, two underwent single-port FLP, one underwent ILA and one underwent both ILA and RFA. All three cases in which hydrops was present at the time of intervention resulted in fetal demise. CONCLUSIONS In-utero interventions aimed at cessation of blood flow in the feeding vessels are a therapeutic option for the management of cases with large chorioangioma. The two-port percutaneous technique appears to improve the efficiency of FLP when a large chorioangioma with large feeding vessels is located in the posterior placenta. We propose that in-utero interventions for large chorioangioma should be initiated prior to the development of fetal hydrops. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Soft tissue deposits, also known as tumour deposits (TDs), have not been studied well in head and neck squamous cell carcinoma (HNSCC) and are not included in any of the staging systems or treatment guidelines. The aim of this systematic review was to determine the prevalence and prognostic implications of TDs in patients with HNSCC. This systematic review of the literature was conducted following the PRISMA guidelines. The PubMed, Embase, and Scopus electronic databases were searched for relevant studies, from inception to August 2022. Although 14 studies qualified for inclusion, only eight were finally included in the review due to the considerable overlap of patients in several studies. Data from 7127 patients were analysed. The pooled prevalence of TDs was 21% (95% confidence interval (CI) 9-33%). The presence of TDs was adversely associated with overall survival and disease-free survival, with hazard ratios of 2.08 (95% CI 1.60-2.70) and 2.56 (95% CI 1.97-3.32), respectively. TDs are detected in a significant number of patients with HNSCC and adversely affect survival. Longitudinal prospective studies are needed to evaluate the prognostic implications of TDs in HNSCC for their potential role in cancer staging and adjuvant treatment planning.
