OBJECTIVE: We comprehensively characterized a large pediatric cohort with focal cortical dysplasia (FCD) type 1 to expand the phenotypic spectrum and to identify predictors of postsurgical outcomes. METHODS: We included pediatric patients with histopathological diagnosis of isolated FCD type 1 and at least 1 year of postsurgical follow-up. We systematically reanalyzed clinical, electrophysiological, and radiological features. The results of this reanalysis served as independent variables for subsequent statistical analyses of outcome predictors. RESULTS: All children (N = 31) had drug-resistant epilepsy with varying impacts on neurodevelopment and cognition (presurgical intelligence quotient [IQ]/developmental quotient scores = 32-106). Low presurgical IQ was associated with abnormal slow background electroencephalographic (EEG) activity and disrupted sleep architecture. Scalp EEG showed predominantly multiregional and often bilateral epileptiform activity. Advanced epilepsy magnetic resonance imaging (MRI) protocols identified FCD-specific features in 74.2% of patients (23/31), 17 of whom were initially evaluated as MRI-negative. In six of eight MRI-negative cases, fluorodeoxyglucose-positron emission tomography (PET) and subtraction ictal single photon emission computed tomography coregistered to MRI helped localize the dysplastic cortex. Sixteen patients (51.6%) underwent invasive EEG. By the last follow-up (median = 5 years, interquartile range = 3.3-9 years), seizure freedom was achieved in 71% of patients (22/31), including seven of eight MRI-negative patients. Antiseizure medications were reduced in 21 patients, with complete withdrawal in six. Seizure outcome was predicted by a combination of the following descriptors: age at epilepsy onset, epilepsy duration, long-term invasive EEG, and specific MRI and PET findings. SIGNIFICANCE: This study highlights the broad phenotypic spectrum of FCD type 1, which spans far beyond the narrow descriptions of previous studies. The applied multilayered presurgical approach helped localize the epileptogenic zone in many previously nonlesional cases, resulting in improved postsurgical seizure outcomes, which are more favorable than previously reported for FCD type 1 patients.

PURPOSE: To evaluate treatment outcomes and toxicity in patients with stage T1-3N0M0 oral cancer treated with surgery followed by high-dose-rate brachytherapy (HDR-BT). METHODS AND MATERIALS: Retrospective study of 50 patients with stage T1-T3N0 tongue and floor-of-mouth cancer who underwent tumour excision (+ elective neck dissection) followed by postoperative HDR-BT due to the presence of negative prognostic factors (close or positive resection margins, lymphovascular and/or perineural invasion, deep invasion). The plastic tube technique (dose: 18 x 3 Gy b.i.d.) was used. Survival outcomes, toxicity, and prognostic factors were evaluated. RESULTS: At a median follow-up of 81 months (range, 4-121), actuarial 5-year local control (LC), nodal control (NC) and progression-free survival (PFS) rates were 79%, 69%, and 64%. After salvage treatment (surgery + external beam radiotherapy), LC, NC, and PFS increased to 87%, 77%, and 72.3%, respectively. Five-year overall survival and cancer-specific survival (CSS) rates were 73% and 77%. Treatmentrelated toxicity included two cases of mandibular osteoradionecrosis and five cases of small soft tissue necrosis. T stage was significantly correlated with nodal control (p=0.02) and CSS (p=0.04). Tumour grade correlated with DFS (p=0.01). CONCLUSION: Postoperative HDR-BT 18 x 3 Gy b.i.d. seems to be an effective method in patients with T1-3N0M0 oral cancer with negative prognostic factors after tumour resection.

OBJECTIVE: Epilepsy surgery in the operculoinsular cortex is challenging due to the difficult delineation of the epileptogenic zone and the high risk of postoperative deficits. METHODS: Pre- and postsurgical data from 30 pediatric patients who underwent operculoinsular cortex surgery at the Motol Epilepsy Center Prague from 2010 to 2022 were analyzed. RESULTS: Focal cortical dysplasia (FCD; n = 15, 50%) was the predominant cause of epilepsy, followed by epilepsy-associated tumors (n = 5, 17%) and tuberous sclerosis complex (n = 2, 7%). In eight patients where FCD was the most likely etiology, the histology was negative. Seven patients (23%) displayed normal magnetic resonance imaging results. Seizures exhibited diverse semiology and propagation patterns (frontal, perisylvian, and temporal). The ictal and interictal electroencephalographic (EEG) findings were mostly extensive. Multimodal imaging and advanced postprocessing were frequently used. Stereo-EEG was used for localizing the epileptogenic zone and eloquent cortex in 23 patients (77%). Oblique electrodes were used as guides for better neurosurgeon orientation. The epileptogenic zone was in the dominant hemisphere in 16 patients. At the 2-year follow-up, 22 patients (73%) were completely seizure-free, and eight (27%) experienced a seizure frequency reduction of >50% (International League Against Epilepsy class 3 and 4). Fourteen patients (47%) underwent antiseizure medication tapering; treatment was completely withdrawn in two (7%). Nineteen patients (63%) remained seizure-free following the definitive outcome assessment (median = 6 years 5 months, range = 2 years to 13 years 5 months postsurgery). Six patients (20%) experienced corona radiata or basal ganglia ischemia; four (13%) improved to mild and one (3%) to moderate hemiparesis. Two patients (7%) operated on in the anterior insula along with frontotemporal resection experienced major complications: pontine ischemia and postoperative brain edema. SIGNIFICANCE: Epilepsy surgery in the operculoinsular cortex can lead to excellent patient outcomes. A comprehensive diagnostic approach is crucial for surgical success. Rehabilitation brings a great chance for significant recovery of postoperative deficits.

PURPOSE: MRI-only adaptive brachytherapy (MRI-ABT) is the state-of-the-art for treating locally advanced cervical cancer (LACC) in combination with concurrent chemoradiotherapy. We aimed to evaluate the pattern of pelvic recurrence after the treatment. MATERIAL AND METHODS: A total of one hundred LACC patients were treated between January 2017 and December 2023 with concurrent chemoradiotherapy of 45 Gy in 25 fractions ± boost to lymphadenopathy (up to a maximum dose of 60 Gy in 25 fractions) with concurrent weekly cisplatin chemotherapy at the dose of 40 mg/m2/week, and MR-ABT. RESULTS: At a median follow-up of 30.2 months, there were 2 local recurrences (2%) and 9 regional pelvic recurrences (9%). The median time to local/regional recurrence was 11 months (range 6-21). For all stages, the 3-year local control was 97.66%, and the 3-year pelvic control was 89.45%. Twenty-four patients died during follow-up; the 3-year overall survival was 75.11%, and the 3-year disease-free survival was 70.97%. CONCLUSION: MRI-ABT combined with external beam radiotherapy and concurrent chemotherapy for LACC demonstrates excellent local and regional pelvic control. Most local/regional recurrences occur inside or at the edge of the external-beam irradiated field. Recurrences inside the field of brachytherapy are rare. Distant recurrences are the predominant cause of death in LACC patients treated with definitive CRT and MRI-ABT.

Wilson disease (WD) primarily presents with hepatic and neurological symptoms. While hepatic symptoms typically precede the neurological manifestations, copper accumulates in the brain already in this patient group and leads to subclinical brain MRI abnormalities including T2 hyperintensities and atrophy. This study aimed to assess brain morphological changes in mild hepatic WD. WD patients without a history of neurologic symptoms and decompensated cirrhosis and control participants underwent brain MRI at 3T scanner including high-resolution T1-weighted images. A volumetric evaluation was conducted on the following brain regions: nucleus accumbens, caudate, pallidum, putamen, thalamus, amygdala, hippocampus, midbrain, pons, cerebellar gray matter, white matter (WM), and superior peduncle, using Freesurfer v7 software. Whole-brain analyses using voxel- and surface-based morphometry were performed using SPM12. Statistical comparisons utilized a general linear model adjusted for total intracranial volume, age, and sex. Twenty-six WD patients with mild hepatic form (30 ± 9 years [mean age ± SD]); 11 women; mean treatment duration 13 ± 12 (range 0-42) years and 28 healthy controls (33 ± 9 years; 15 women) were evaluated. Volumetric analysis revealed a significantly smaller pons volume and a trend for smaller midbrain and cerebellar WM in WD patients compared to controls. Whole-brain analysis revealed regions of reduced volume in the pons, cerebellar, and lobar WM in the WD group. No significant differences in gray matter density or cortical thickness were found. Myelin or WM in general seems vulnerable to low-level copper toxicity, with WM volume loss showing promise as a marker for assessing brain involvement in early WD stages.

BACKGROUND AND OBJECTIVE: Non-muscle-invasive bladder cancer (NMIBC) poses a significant clinical challenge, particularly when failing bacillus Calmette-Guérin (BCG) therapy, necessitating alternative treatments. Despite radical cystectomy being the recommended treatment, many patients are unfit or unwilling to undergo this invasive procedure, highlighting the need for effective bladder-sparing therapies. This review aims to summarize and report the evidence on the efficacy and to estimate the costs of bladder-preserving strategies used in NMIBC recurrence after failure of intravesical BCG therapy. METHODS: We systematically searched online databases for prospective studies investigating intravesical therapy, systemic therapy, or combination of both in patients treated previously with BCG. Owing to significant heterogeneity across the studies, a meta-analysis was inappropriate. A sensitivity analysis was performed in an exploratory manner. We used a decision-analytic Markov model to compare novel U.S. Food and Drug Administration-approved treatments with a 2-yr time horizon. KEY FINDINGS AND LIMITATIONS: A total of 57 studies published between 1998 and 2024, with 68 unique study arms and consisting of 2589 patients, were identified. The 3-mo overall response rate (ORR) across all studies, complete response rate (CRR) in concomitant carcinoma in situ (CIS) or CIS only disease, and recurrence-free rate (RFR) in papillary disease were estimated to be 52.4% (95% confidence interval [CI]: 45.4-59.2), 52.8% (95% CI: 42.9-62.6), and 26.4% (95% CI: 13.3-45.6), respectively. The 12-mo ORR, CRR, and RFR were estimated to be 78% (95% CI: 52.9-91.8), 27.8% (95% CI: 21.3-35.4), and 25.4% (95% CI: 18.2-34.2), respectively. The progression rate was estimated to be 13% (95% CI: 9-18.2). The mean proportion of patients treated with radical cystectomy was estimated to be 24.7 (range 0-85.7). The reported toxicity grades were overall mild, with a median of 3.4% (range 0-33.3%) participants experiencing a dose limiting toxicity. Compared with using radical cystectomy to treat patients failing BCG therapy, at a willingness-to-pay threshold of 100 000 USD, nadofaragene firadenovec was cost effective, with an incremental cost-effectiveness ratio (ICER) of 10 014 USD per quality-adjusted life year (QALY), while nogapendekin alfa inbakicept was less cost effective than nadofaragene firadenovec (ICER of 44 602 USD per QALY). Pembrolizumab, which dominated, was both less costly and more effective than the other strategies. CONCLUSIONS AND CLINICAL IMPLICATIONS: Salvage bladder-sparing therapies show a response rate of around 50% at 3 mo in patients with NMIBC failing BCG. However, long-term data are heterogeneous. Nevertheless, recently developed agents show promising tumor control activity. In the rapidly evolving landscape of urothelial cancer, some of these treatment strategies might be cost effective and improve patients' quality of life. The findings of our review highlight the need for novel, more effective therapeutic strategies. PATIENT SUMMARY: In this study, we reviewed the evidence on the efficacy of bladder-preserving strategies used in patients with bladder cancer recurrence after failing bacillus Calmette-Guérin (BCG) therapy. We found that these strategies show a response rate of around 50% at 3 mo. However, long-term data are heterogeneous. Nevertheless, recently developed agents show promising tumor control activity. In the rapidly evolving landscape of urothelial cancer, some of these treatment strategies might be cost effective and improve patients' quality of life.

PURPOSE: CheckMate 914 is a two-part, randomized phase III trial evaluating adjuvant nivolumab plus ipilimumab (part A) or adjuvant nivolumab monotherapy (part B) versus placebo in mutually exclusive populations of patients with localized renal cell carcinoma (RCC) at high risk of postnephrectomy recurrence. Part A showed no disease-free survival (DFS) benefit for adjuvant nivolumab plus ipilimumab versus placebo. We report results from part B. METHODS: Patients were randomly assigned (2:1:1) to nivolumab (240 mg once every 2 weeks for up to 12 doses), placebo, or nivolumab (240 mg once every 2 weeks for up to 12 doses) plus ipilimumab (1 mg/kg once every 6 weeks for up to four doses). The planned treatment duration was 24 weeks (approximately 5.5 months). The primary end point was DFS per blinded independent central review (BICR) for nivolumab versus placebo; safety was a secondary end point. RESULTS: Overall, 825 patients were randomly assigned to nivolumab (n = 411), placebo (n = 208), or nivolumab plus ipilimumab (n = 206). With a median follow-up of 27.0 months (range, 18.0-42.4), the primary end point of improved DFS per BICR with nivolumab versus placebo was not met (hazard ratio [HR], 0.87 [95% CI, 0.62 to 1.21]; P = .40); the median DFS was not reached in either arm, and 18-month DFS rates were 78.4% versus 75.4%. The HR for DFS per investigator was 0.80 (95% CI, 0.58 to 1.12; P = .19). Grade 3-4 all-cause adverse events (AEs) occurred in 17.2%, 15.0%, and 28.9% of patients with nivolumab, placebo, and nivolumab plus ipilimumab, respectively. Any-grade treatment-related AEs led to discontinuation in 9.6%, 1.0%, and 28.4%, respectively. CONCLUSION: Part B of CheckMate 914 did not meet the primary end point of improved DFS for nivolumab versus placebo in patients with localized RCC at high risk of postnephrectomy recurrence.

PURPOSE: Dual velocity encoding PC-MRI can produce spurious artifacts when using high ratios of velocity encoding values (VENCs), limiting its ability to generate high-quality images across a wide range of encoding velocities. This study aims to propose and compare dual-VENC correction methods for such artifacts. THEORY AND METHODS: Two denoising approaches based on spatiotemporal regularization are proposed and compared with a state-of-the-art method based on sign correction. Accuracy is assessed using simulated data from an aorta and brain aneurysm, as well as 8 two-dimensional (2D) PC-MRI ascending aorta datasets. Two temporal resolutions (30,60) ms and noise levels (9,12) dB are considered, with noise added to the complex magnetization. The error is evaluated with respect to the noise-free measurement in the synthetic case and to the unwrapped image without additional noise in the volunteer datasets. RESULTS: In all studied cases, the proposed methods are more accurate than the Sign Correction technique. Using simulated 2D+T data from the aorta (60 ms, 9 dB), the Dual-VENC (DV) error 0.82±0.07$$ 0.82\pm 0.07 $$ is reduced to: 0.66±0.04$$ 0.66\pm 0.04 $$ (Sign Correction); 0.34±0.04$$ 0.34\pm 0.04 $$ and 0.32±0.04$$ 0.32\pm 0.04 $$ (proposed techniques). The methods are found to be significantly different (p-value <0.05$$ <0.05 $$ ). Importantly, brain aneurysm data revealed that the Sign Correction method is not suitable, as it increases error when the flow is not unidirectional. All three methods improve the accuracy of in vivo data. CONCLUSION: The newly proposed methods outperform the Sign Correction method in improving dual-VENC PC-MRI images. Among them, the approach based on temporal differences has shown the highest accuracy.

PURPOSE: STereotactic Arrhythmia Radioablation (STAR) showed promising results in patients with refractory ventricular tachycardia. However, clinical data are scarce and heterogeneous. The STOPSTORM.eu consortium was established to investigate and harmonize STAR in Europe. The primary goal of this benchmark study was to investigate current treatment planning practice within the STOPSTORM project as a baseline for future harmonization. METHODS AND MATERIALS: Planning target volumes (PTVs) overlapping extracardiac organs-at-risk and/or cardiac substructures were generated for 3 STAR cases. Participating centers were asked to create single-fraction treatment plans with 25 Gy dose prescriptions based on in-house clinical practice. All treatment plans were reviewed by an expert panel and quantitative crowd knowledge-based analysis was performed with independent software using descriptive statistics for International Commission on Radiation Units and Measurements report 91 relevant parameters and crowd dose-volume histograms. Thereafter, treatment planning consensus statements were established using a dual-stage voting process. RESULTS: Twenty centers submitted 67 treatment plans for this study. In most plans (75%) intensity modulated arc therapy with 6 MV flattening filter free beams was used. Dose prescription was mainly based on PTV D95% (49%) or D96%-100% (19%). Many participants preferred to spare close extracardiac organs-at-risk (75%) and cardiac substructures (50%) by PTV coverage reduction. PTV D0.035cm3 ranged from 25.5 to 34.6 Gy, demonstrating a large variety of dose inhomogeneity. Estimated treatment times without motion compensation or setup ranged from 2 to 80 minutes. For the consensus statements, a strong agreement was reached for beam technique planning, dose calculation, prescription methods, and trade-offs between target and extracardiac critical structures. No agreement was reached on cardiac substructure dose limitations and on desired dose inhomogeneity in the target. CONCLUSIONS: This STOPSTORM multicenter treatment planning benchmark study not only showed strong agreement on several aspects of STAR treatment planning, but also revealed disagreement on others. To standardize and harmonize STAR in the future, consensus statements were established; however, clinical data are urgently needed for actionable guidelines for treatment planning.

BACKGROUND AND PURPOSE: Cognitive impairment (CI) in multiple sclerosis (MS) is associated with bidirectional changes in resting-state centrality measures. However, practicable functional magnetic resonance imaging (fMRI) biomarkers of CI are still lacking. The aim of this study was to assess the graph-theory-based degree rank order disruption index (kD) and its association with cognitive processing speed as a marker of CI in patients with MS (PwMS) in a secondary cross-sectional fMRI analysis. METHODS: Differentiation between PwMS and healthy controls (HCs) using kD and its correlation with CI (Symbol Digit Modalities Test) was compared to established imaging biomarkers (regional degree, volumetry, diffusion-weighted imaging, lesion mapping). Additional associations were assessed for fatigue (Fatigue Scale for Motor and Cognitive Functions), gait and global disability. RESULTS: Analysis in 56 PwMS and 58 HCs (35/27 women, median age 45.1/40.5 years) showed lower kD in PwMS than in HCs (median -0.30/-0.06, interquartile range 0.55/0.54; p = 0.009, Mann-Whitney U test), yielding acceptable yet non-superior differentiation (area under curve 0.64). kD and degree in medial prefrontal cortex (MPFC) correlated with CI (kD/MPFC Spearman's ρ = 0.32/-0.45, p = 0.019/0.001, n = 55). kD also explained fatigue (ρ = -0.34, p = 0.010, n = 56) but neither gait nor disability. CONCLUSIONS: kD is a potential biomarker of CI and fatigue warranting further validation.
