Abstract Introduction Tn polyagglutination syndrome is a rare disorder that has been reported on only a few occasions in the literature, and, to the best of our knowledge, never before in the context of febrile neutropenia. Case presentation We report the case of a 26-year-old Caucasian woman who presented to our emergency department complaining of a persistent fever over the previous three days. She had a history of long-standing refractory pancytopenia with multi-lineage dysplasia and severe neutropenia, but she had rarely experienced infection. The results of a physical examination and multiple laboratory tests were unremarkable. While investigating the possible causes of the refractory, long-standing pancytopenia, the possibility of a polyagglutinable state was suggested. Blood samples were sent to the laboratory for an analysis of mixed-field seed lectin agglutination assay. A serum lectin panel confirmed the final diagnosis of Tn-activation. Conclusions We should include Tn-activation in our differential whenever we encounter cases of refractory long-standing idiopathic cytopenias and inconclusive bone marrow results displaying multi-lineage dysplasia. Novel genetic techniques have recently revealed the interesting pathophysiology of this phenomenon. The recognition and inclusion of Tn polyagglutination syndrome in our differential diagnoses has important clinical implications, given its main associated features, such as severe thrombocytopenia and neutropenia, which are usually linked to a benign clinical course and prognosis. Increased awareness of the polyagglutinable disorders will potentially decrease the need for invasive and costly medical interventions and also raises the need for monitoring of this specific sub-set of patients. In addition, the study of the expression and implications of Tn, and other similar antigens, offers a fascinating perspective for the study of its role in the diagnosis, prognosis and immunotherapy of solid tumors and hematological malignancies. The infrequency with which Tn polyagglutination syndrome is encountered, its clinical features and its pathophysiology make it a formidable diagnostic challenge.

Un problema ambiental lo constituyen los compuestos orgánicos refractarios como los colorantes, que interfieren en los procesos fotosintéticos que realizan los organismos en cuerpos hídricos. Estos contaminantes se encuentran presentes en las aguas residuales de industrias como la textil, papelera, curtiembre, farmacéutica, entre otros, cuyos procesos generan grandes volúmenes de aguas residuales. El objetivo de esta investigación fue remover colorantes de efluente sintético de industria textil, aplicando tecnología avanzada, para lo cual se empleó electrocoagulación. Esto permite llevar a cabo un tratamiento sin utilizar reactivos, usando cargas eléctricas que desestabilizan las partículas coloidales, facilitando su precipitación, para lo cual se utilizaron electrodos de hierro con 0.8 mm de separación. La metodología aplicada se basa en las variaciones de densidad de corriente, pH y tiempo de residencia. Las variables de respuesta son porcentaje de remoción de color y la demanda química de oxígeno. Como resultado de las experimentaciones, se obtuvo una remoción del 97.57 % de demanda química de oxígeno y 99.11 % de color a densidad de corriente 27.9 A/m2, pH de 10 y en un tiempo de reacción de 8 min. Esta experiencia puede ser aplicada con otro tipo de efluentes.

Background: Neomorphic isocitrate dehydrogenase (IDH) mutations lead to the accumulation of 2-hydroxyglutarate (2-HG), an oncometabolite implicated in tumor progression via inhibitory effects on alpha-ketoglutarate. Moreover, mutant IDH-dependent accumulation of 2-HG results in homologous recombination deficiency (HRD), which preclinically renders tumors sensitive to poly(adenosine diphosphate ribose) polymerase inhibitors. Here, the results of the cholangiocarcinoma (CCA) arm of the National Cancer Institute (NCI) 10129 olaparib in IDH-mutant solid tumors basket trial are reported., Methods: Olaparib 300 mg twice daily was evaluated in an open-label, phase 2 clinical trial for treatment-refractory IDH-mutant solid tumors. Patients in the IDH-mutant CCA arm enrolled in two cohorts: (1) IDH inhibitor (IDHi) pretreated and (2) IDHi untreated, with a primary end point of overall response rate., Results: NCI 10129 enrolled 30 patients with IDH-mutant CCA with no objective responses seen, and recruitment was closed early. Median progression-free survival (PFS) was 2.4 months (95% CI, 1.9 to 6.5 months) and median overall survival was 12.9 months (95% CI, 6.3 months to not reached). Eight patients (27%) had clinical benefit (CB), with a PFS of ≥6 months. Patients with CB had lower baseline 2-HG levels compared to those without CB (1.4 vs. 5.9 µmol/L; p = .01)., Conclusions: Olaparib does not have sufficient single-agent activity to warrant further development in IDH-mutant CCA. However, a subgroup of patients demonstrated CB, and exploratory analysis revealed this subgroup to be enriched for lower baseline 2-HG levels. Future clinical trials leveraging the HRD properties of IDH mutations are warranted with enhanced patient selection and novel combination therapies., (© 2025 American Cancer Society.)

Chondrosarcomas, a rare form of bone sarcomas with multiple subtypes, pose a pressing clinical challenge for patients with advanced or metastatic disease. The lack of US Food and Drug Administration (FDA)-approved medications underscores the urgent need for further research and development in this area. Patients and their families face challenges as there are no systemic therapeutic options available with substantial effectiveness. A significant number (50-80%) of chondrosarcomas have a mutation in the isocitrate dehydrogenase (IDH) genes. This review focuses on IDH-mediated pathogenesis and recent pharmacological advances with novel IDH inhibitors, explores their potential therapeutic value, and proposes potential future avenues for clinical trials combining IDH inhibitors with other systemic agents for chondrosarcomas., Competing Interests: Declarations.

Background/Objectives: Early weaning management followed by energy supplementation can lead to metabolic alterations in the calf that exert long-term effects on the animal's health and performance. It is believed that the main molecular basis underlying these metabolic adaptations are epigenetic mechanisms that regulate, activate, or silence genes at different stages of development and/or in response to different environmental stimuli. However, little is known about postnatal metabolic programming in Bos indicus . Therefore, this study aimed to compare the DNA methylation profile of Nellore animals submitted to conventional and early weaning and to correlate the findings with genes differentially expressed in the Longissimus thoracis skeletal muscle of Bos indicus cattle. Methods: For this, we used Reduced Representation Bisulfite Sequencing (RRBS) and RNA-Sequencing techniques to prospect differentially methylated genes (DMGs). Results: A total of 481 differentially methylated regions were identified, with 52% (250) being hypermethylated and 48% (231) hypomethylated. Functional enrichment analysis of 53 differentially methylated and differentially expressed genes was performed. The main enriched terms and pathways were associated with 3'-5'-cyclic adenosine monophosphate ( cAMP ) signaling, which presents the upregulated adenylate cyclase 3 ( ADCY3 ) gene and significatively hypomethylated in the promoter region. Alterations in cAMP signaling are involved in numerous processes, many of them related to lipid metabolism. The relative differential expression of key genes of this pathway demonstrates the relationship between cAMP signaling and de novo lipogenesis. Conclusions : These findings suggest an important role of postnatal metabolic programming through DNA methylation mechanisms in determining fat deposition in beef.

Background: Approximately half of patients with localised, high-risk soft tissue sarcoma of the extremity develop metastases. We aimed to assess whether the addition of pembrolizumab to preoperative radiotherapy and surgery would improve disease-free survival., Methods: We completed an open-label, randomised clinical trial in patients with grade 2 or 3, stage III undifferentiated pleomorphic sarcoma or dedifferentiated or pleomorphic liposarcoma of the extremity and limb girdle. Patients were enrolled at 20 academic institutions in Australia, Canada, Italy, and the USA. Patients were randomly assigned to preoperative radiotherapy then surgery (control group) or preoperative pembrolizumab with radiotherapy (initiated 1-14 days after the first dose of pembrolizumab) then surgery and postoperative pembrolizumab (experimental group). Pembrolizumab (200 mg intravenously every 3 weeks) was administered as three neoadjuvant cycles (before, during, and after radiotherapy) and 14 or less adjuvant cycles. Primary endpoint was disease-free survival. This study is registered with ClincialTrials.gov (NCT03092323)., Findings: Between Nov 18, 2017, and Nov 14, 2023, 143 participants were randomly assigned to treatment. A modified intention-to-treat analysis of 127 patients with median follow-up of 43 months showed that the experimental group (n=64) had significantly longer disease-free survival than the control group (n=63; log-rank one-sided p=0·035; hazard ratio [HR] 0·61; 90% CI 0·39-0·96). The 2-year disease-free survival increased by 15% with addition of pembrolizumab: 52% (90% CI 42-64) and 67% (90% CI 58-78) for the control and experimental groups, respectively. Disease-free survival was similarly improved with pembrolizumab for the intention-to-treat patient population (HR 0·61 [90% CI 0·39-0·95]). Grade 3 or higher adverse events occurred more frequently in the experimental group (56%) than the control group (31%)., Interpretation: Addition of pembrolizumab to preoperative radiotherapy and surgery improves disease-free survival for patients with stage III undifferentiated pleomorphic sarcoma and pleomorphic or dedifferentiated liposarcoma of the extremity, which establishes a promising new treatment option for these patients., Funding: Stand Up to Cancer and Merck Sharp & Dohme., Competing Interests: Declaration of interests YMM reports leadership roles in ASTRO and NRG Oncology and an honorarium from the University of Wisconsin–Madison.

Purpose: Epithelioid hemangioendothelioma (EHE) is a rare vascular cancer with pathogenic TAZ-CAMTA1 (calmodulinbinding transcription activator 1) operating as an oncogenic driver through activation of the MAPK pathway. Trametinib is an inhibitor of MEK, a critical kinase in the MAPK pathway. We sought to evaluate the effect of trametinib in patients with EHE., Patients and Methods: A phase 2 trial of trametinib was conducted in patients with locally advanced or metastatic EHE. Eligibility requirements included evidence of tumor progression or presence of EHE-related pain requiring opiates for management before enrollment. The primary endpoint was objective response rate (ORR) as per RECIST1.1 in cases with TAZ- CAMTA1 confirmed by fusion-FISH. Secondary objectives were to estimate ORR for all patients, median progression-free survival (PFS), 2-year overall survival (OS) rate, patient safety, and change in patient-reported global health and pain scores per PROMIS questionnaires., Results: 44 patients enrolled and 42 started trametinib. TAZ- CAMTA1 was detected in 27 tumor samples. TheORRwas 3.7%[95% confidence interval (CI), 0.094-19.0], median PFS was 10.4 months (95%CI, 7.1-NA), and 2-year OS rate was 33.3%(95%CI, 19.1-58.2) in the target population. Median pain intensity and interference scores improved significantly after 4 weeks of trametinib in patients using opiates. Common adverse events related to trametinib were rash, fatigue, nausea/vomiting, diarrhea/constipation, alopecia, and edema; one grade 5 ARDS/pneumonitis was related to trametinib., Conclusions: Trametinib was associated with reduction in EHE-related pain and median PFS of more than 6 months, providing palliative benefit in patients with advanced EHE, but the trial did not meet the ORR goal.

Objective: Breast angiosarcoma is a tumor that can arise as a primary breast tumor or in association with prior radiation therapy. Angiosarcomas are uniquely sensitive to paclitaxel. This study evaluated the impact neoadjuvant paclitaxel (NAC) therapy has on surgical outcomes, tumor recurrence, and survival in breast angiosarcomas., Methods: Patients with angiosarcoma of the breast, either primary or radiation-associated, were identified from a prospective institutional database. Patients receiving NAC were compared to those treated with upfront surgery. Clinical and pathological variables were compared using Student's t-test or Fisher's exact test, differences in survival were calculated using Kaplan-Meier methods., Results: Twenty-four patients with angiosarcoma of the breast were identified, 10 with primary angiosarcoma and 14 with radiation-associated angiosarcoma. Twelve patients received NAC, 6 of each with primary angiosarcoma or radiation-associated angiosarcoma. Of these 12 patients, 11 had a margin negative resection (91%) of which, nine had a complete pathological response on surgical pathology. Of the 12 surgery-first patients, four (n = 4/12, 33%) had positive surgical margins, two of the four underwent reoperation. With a median follow-up of 16 months, four NAC patients had recurrence (33%) compared to six patients in the surgery-first group (58%) (p = 0.41). While not statistically significant, NAC patients had a 33% less risk of recurring compared to surgery-first patients ([hazard ratio =0.67 (95% confidence interval 0.16-2.72; p = 0.6])., Conclusion: NAC for breast angiosarcoma may be associated with high rates of complete pathological response and margin-negative resection. However, this did not impact overall survival. Future prospective control studies and longer follow-up periods are warranted to understand the impact on recurrence and survival., (© 2024 The Author(s).

Desmoid tumors (DTs) are rare and locally aggressive with a high rate of local recurrence even with optimal surgical resection. Systemic treatments are often utilized for desmoid cases with high risk of surgical morbidity or for local and symptomatic control of recurrent disease. However, the systemic treatment options for DTs are limited with limited responses. Avapritinib is a tyrosine kinase inhibitor (TKI) approved in 2020 for adults with unresectable or metastatic gastrointestinal (GI) stromal tumors (GISTs) harboring a platelet-derived growth factor receptor alpha (PDGFRA) Exon 18 mutation, including D842V mutations. In this case report, we describe a 55-year-old man with a history of D842V-mutant gastric GIST who presented several years after complete resection of the GIST with an enlarging soft tissue mass in the small intestine. After a nondiagnostic biopsy, the patient was started on avapritinib due to concerns for recurrent D842V-mutant GIST. The tumor had a partial response to treatment by RECIST 1.1 criteria, and the patient underwent surgical resection. The final pathology report revealed a sporadic DT. To our knowledge, this is the first known description of the activity of avapritinib in the treatment of a sporadic mesenteric DT, which is relevant given the limited treatment options for patients with this diagnosis. This clinical finding may be worth exploring in a dedicated clinical trial., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Rebecca Ganzon et al.)

Emerging evidence supports the important role of the tumor microbiome in oncogenesis, cancer immune phenotype, cancer progression, and treatment outcomes in many malignancies. In this study, we investigated the metastatic melanoma tumor microbiome and its potential roles in association with clinical outcomes, such as survival, in patients with metastatic disease treated with immune checkpoint inhibitors (ICI). Baseline tumor samples were collected from 71 patients with metastatic melanoma before treatment with ICIs. Bulk RNA sequencing (RNA-seq) was conducted on the formalin-fixed, paraffin-embedded and fresh frozen tumor samples. Durable clinical benefit (primary clinical endpoint) following ICIs was defined as overall survival >24 months and no change to the primary drug regimen (responders). We processed RNA-seq reads to carefully identify exogenous sequences using the {exotic} tool. The age of the 71 patients with metastatic melanoma ranged from 24 to 83 years, 59% were male, and 55% survived >24 months following the initiation of ICI treatment. Exogenous taxa were identified in the tumor RNA-seq, including bacteria, fungi, and viruses. We found differences in gene expression and microbe abundances in immunotherapy-responsive versus nonresponsive tumors. Responders showed significant enrichment of bacteriophages in the phylum Uroviricota, and nonresponders showed enrichment of several bacteria, including Campylobacter jejuni. These microbes correlated with immune-related gene expression signatures. Finally, we found that models for predicting prolonged survival with immunotherapy using both microbe abundances and gene expression outperformed models using either dataset alone. Our findings warrant further investigation and potentially support therapeutic strategies to modify the tumor microbiome in order to improve treatment outcomes with ICIs., Significance: We analyzed the tumor microbiome and interactions with genes and pathways in metastatic melanoma treated with immunotherapy and identified several microbes associated with immunotherapy response and immune-related gene expression signatures. Machine learning models that combined microbe abundances and gene expression outperformed models using either dataset alone in predicting immunotherapy responses., (©2024 The Authors; Published by the American Association for Cancer Research.)

Tumor hypoxia has been shown to predict poor patient outcomes in several cancer types, partially because it reduces radiation's ability to kill cells. We hypothesized that some of the clinical effects of hypoxia could also be due to its impact on the tumor microbiome. Therefore, we examined the RNA sequencing data from the Oncology Research Information Exchange Network database of patients with colorectal cancer treated with radiotherapy. We identified microbial RNAs for each tumor and related them to the hypoxic gene expression scores calculated from host mRNA. Our analysis showed that the hypoxia expression score predicted poor patient outcomes and identified tumors enriched with certain microbes such as Fusobacterium nucleatum. The presence of other microbes, such as Fusobacterium canifelinum, predicted poor patient outcomes, suggesting a potential interaction between hypoxia, the microbiome, and radiation response. To experimentally investigate this concept, we implanted CT26 colorectal cancer cells into immune-competent BALB/c and immune-deficient athymic nude mice. After growth, in which tumors passively acquired microbes from the gastrointestinal tract, we harvested tumors, extracted nucleic acids, and sequenced host and microbial RNAs. We stratified tumors based on their hypoxia score and performed a metatranscriptomic analysis of microbial gene expression. In addition to hypoxia-tropic and -phobic microbial populations, analysis of microbial gene expression at the strain level showed expression differences based on the hypoxia score. Thus, hypoxia gene expression scores seem to associate with different microbial populations and elicit an adaptive transcriptional response in intratumoral microbes, potentially influencing clinical outcomes., Significance: Tumor hypoxia reduces radiotherapy efficacy. In this study, we explored whether some of the clinical effects of hypoxia could be due to interaction with the tumor microbiome. Hypoxic gene expression scores associated with certain microbes and elicited an adaptive transcriptional response in others that could contribute to poor clinical outcomes., (©2024 The Authors; Published by the American Association for Cancer Research.)

Background: Tenosynovial giant cell tumour (TGCT) is a locally aggressive neoplasm for which few systemic treatment options exist. This study evaluated the efficacy and safety of vimseltinib, an oral, switch-control, CSF1R inhibitor, in patients with symptomatic TGCT not amenable to surgery., Methods: MOTION is a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial done in 35 specialised hospitals in 13 countries. Eligible patients were adults (aged ≥18 years) with a histologically confirmed diagnosis of TGCT for which surgical resection could potentially worsen functional limitation or cause severe morbidity. Patients were randomly assigned (2:1) with interactive response technology to vimseltinib (30 mg orally twice weekly) or placebo, administrated in 28-day cycles for 24 weeks. Patients and site personnel were masked to treatment assignment until week 25, unless progressive disease was confirmed earlier. The primary endpoint was objective response rate by independent radiological review using Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST) at week 25 in the intention-to-treat population. Safety was assessed in all patients who received the study drug. The trial is registered with ClinicalTrials.gov, NCT05059262, and enrolment is complete., Findings: Between Jan 21, 2022, and Feb 21, 2023, 123 patients were randomly assigned (83 to vimseltinib and 40 to placebo). 73 (59%) patients were female and 50 (41%) were male. Nine (11%) of 83 patients assigned to vimseltinib and five (13%) of 40 patients assigned to placebo discontinued treatment before week 25; one patient in the placebo group did not receive any study drug. Objective response rate per RECIST was 40% (33 of 83 patients) in the vimseltinib group vs 0% (none of 40) in the placebo group (difference 40% [95% CI 29-51]; p<0·0001). Most treatment-emergent adverse events (TEAEs) were grade 1 or 2; the only grade 3 or 4 TEAE that occurred in more than 5% of patients receiving vimseltinib was increased blood creatine phosphokinase (eight [10%] of 83). One patient in the vimseltinib group had a treatment-related serious TEAE of subcutaneous abscess. No evidence of cholestatic hepatotoxicity or drug-induced liver injury was noted., Interpretation: Vimseltinib produced a significant objective response rate and clinically meaningful functional and symptomatic improvement in patients with TGCT, providing an effective treatment option for these patients., Funding: Deciphera Pharmaceuticals., Competing Interests: Declaration of interests VB reports institutional research funding from Deciphera Pharmaceuticals and participation on a medical advisory board for Deciphera Pharmaceuticals.

Microgrids (MGs) based on renewable energies have emerged as a proficient strategy for tackling power quality issues in conventional distribution networks. Nonetheless, MG systems require a suitable control scheme to supply energy optimally towards the electrical grid. This paper presents an innovative framework for designing hybrid Proportional-Resonant (PR) controllers with Linear Quadratic Regulators (LQR), PR+LQR, which merge relevant properties of PR and LQR controllers. This method simultaneously determines the MG control parameters and the current unbalanced factor generated at the distribution network. We select the traditional IEEE 13-bus test feeder network and place two MGs at strategic locations to validate our approach. Moreover, we use the Grey Wolf Optimizer (GWO) to find control parameters through a reliable fitness function that leads to high-performance microgrids. Finally, we conceive several tests to assess the efficacy of GWO for tuning the hybrid controller and compare the resulting data across distinct realistic operation conditions representing power quality events. So, we choose four case studies considering different renewable energy penetration indexes and power factors and evaluate the effects of the MGs over the distribution grid. We also compare the proposed hybrid PR+LQR controller against closely-related alternatives from the literature and validate its robustness and stability through the disk margin approach and the Nyquist criterion. Our numerical simulations prove that hybrid controllers driven by GWO are highly reliable strategies, yielding an average unbalanced current reduction of 30.03%., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Ivan Amaya reports financial support was provided by National Council for Science and Technology.

Radiation-associated sarcomas (RASs) are rare tumors with limited contemporary data to inform prognostication and management. We sought to identify the clinical presentation, patterns of care, and prognostic factors of RASs. RAS patients treated at a single institution from 2015 to 2021 were retrospectively reviewed for clinicopathologic variables, treatment strategies, and outcomes. Thirty-eight patients were identified with a median follow-up of 30.5 months. The median age at RAS diagnosis was 68.4 years (27.9-85.4), with a median latency from index radiotherapy (RT) of 9.1 years (3.7-46.3). RAS histologies included angiosarcoma (26%), undifferentiated pleomorphic sarcoma (21%), and osteosarcoma (18%). Most were high-grade (76%). Genomic profiling revealed low tumor mutational burden, frequent inactivating TP53 mutations (44%), CDKN2A deletions (26%), and MYC amplifications (22%), particularly in breast angiosarcomas. Of 38 patients, 33 presented with localized disease, 26 of whom were treated with curative intent. Overall, the median progression-free survival (PFS) was 9.5 months (1.4-34.7), and the overall survival (OS) was 11.1 months (0.6-31.6). Patients with localized vs. metastatic RASs had a longer PFS (HR, 3.0 [1.1-8.5]; p = 0.03) and OS (HR, 3.0 [1.04-8.68]; p = 0.03). Among localized RAS patients, high grade was associated with shorter OS (HR, 4.6 [1.04-20.30]; p = 0.03) and resection with longer OS (mean 58.8 vs. 6.1 months, HR, 0.1 [0.03-0.28]; p < 0.001). Among patients undergoing resection, negative margins were associated with improved OS (mean 71.0 vs. 15.5 months, HR, 5.1 [1.4-18.2]; p = 0.006). Patients with localized disease, particularly those undergoing R0 resection, demonstrated significantly better outcomes. Novel strategies are urgently needed to improve treatment outcomes in this challenging group of diseases.

Blood-based liquid biopsy is increasingly used in clinical care of patients with cancer, and fraction of tumor-derived DNA in circulation (tumor fraction; TFx) has demonstrated clinical validity across multiple cancer types. To determine TFx, shallow whole-genome sequencing of cell-free DNA (cfDNA) can be performed from a single blood sample, using an established computational pipeline (ichorCNA), without prior knowledge of tumor mutations, in a highly cost-effective manner. We describe assay validation of this approach to facilitate broad clinical application, including evaluation of assay sensitivity, precision, repeatability, reproducibility, pre-analytic factors, and DNA quality/quantity. Sensitivity to detect TFx of 3% (lower limit of detection) was 97.2% to 100% at 1× and 0.1× mean sequencing depth, respectively. Precision was demonstrated on distinct sequencing instruments (HiSeqX and NovaSeq) with no observable differences. The assay achieved prespecified 95% agreement of TFx across replicates of the same specimen (repeatability) and duplicate samples in different batches (reproducibility). Comparison of samples collected in EDTA and Streck tubes from single venipuncture in 23 patients demonstrated that EDTA or Streck tubes were comparable if processed within 8 hours. On the basis of a range of DNA inputs (1 to 50 ng), 20 ng cfDNA is the preferred input, with 5 ng minimum acceptable. Overall, this shallow whole-genome sequencing of cfDNA and ichorCNA approach offers sensitive, precise, and reproducible quantitation of TFx, facilitating assay application in clinical cancer care., (Copyright © 2024 Association for Molecular Pathology and American Society for Investigative Pathology.

Objectives. Atypical hemolytic uremic syndrome (aHUS) is a rare complement-mediated kidney disease with genetic predisposition and represents up to 10% of pediatric hemolytic uremic syndrome (HUS) cases. Few studies have evaluated aHUS in Latin American population. We studied a Colombian pediatric cohort to delineate disease presentation and outcomes. Methods. A multicenter cohort of 27 Colombian children with aHUS were included. Patients were grouped by age at onset. Clinical features were compared using analysis of variance (ANOVA) and Fisher exact tests. Renal biopsy was performed on 6 patients who were suspected of having other renal diseases before aHUS diagnosis. Results. Most patients were male (70%). The onset of aHUS occurred frequently before age 4 years (60%) and followed gastroenteritis as the main triggering event (52%). Age groups showed comparable clinical presentation, disease severity, treatment, and outcomes. Pulmonary involvement (67%) was the main extrarenal manifestation, particularly in the 1 to 7 age group ( P  = .01). Renal biopsies were as follows: 3 had membranoproliferative glomerulonephritis (MPGN) type I, one MPGN type III, one C3-glomerulonephritis, and one rapidly progressive GN. Genetic screening was available in 6 patients and identified 2x CFHR5 , 2xMCP , 1x ADAMTS13/THBD , and 1x DGKE mutations. A total of 15 relapses were seen, of which 8 (72%) occurred in the 1 to 7 age group. The renal outcome was not significantly different regardless of age group. Conclusion. In our cohort, we observed a relatively high frequency of extrarenal involvement at first presentation represented by pulmonary manifestations. The renal prognosis at initial presentation was worse than in previous reports., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background and Purpose: A bolus is required when treating scalp lesions with photon radiation therapy. Traditional bolus materials face several issues, including air gaps and setup difficulty due to irregular, convex scalp geometry. A 3D-milled bolus is custom-formed to match individual patient anatomy, allowing improved dose coverage and homogeneity. Here, we describe the creation process of a 3D-milled bolus and report the outcomes for patients with scalp malignancies treated with Volumetric Modulated Arc Therapy (VMAT) utilizing a 3D-milled bolus., Materials and Methods: Twenty-two patients treated from 2016 to 2022 using a 3D-milled bolus and VMAT were included. Histologies included squamous cell carcinoma ( n = 14, 64%) and angiosarcoma ( n = 8, 36%). A total of 7 (32%) patients were treated in the intact and 15 (68%) in the postoperative setting. The median prescription dose was 66.0 Gy (range: 60.0-69.96)., Results: The target included the entire scalp for 8 (36%) patients; in the remaining 14 (64%), the median ratio of planning target volume to scalp volume was 35% (range: 25-90%). The median dose homogeneity index was 1.07 (range: 1.03-1.15). Six (27%) patients experienced acute grade 3 dermatitis and one (5%) patient experienced late grade 3 skin ulceration. With a median follow-up of 21.4 months (range: 4.0-75.4), the 18-month rates of locoregional control and overall survival were 75% and 79%, respectively., Conclusions: To our knowledge, this is the first study to report the clinical outcomes for patients with scalp malignancies treated with the combination of VMAT and a 3D-milled bolus. This technique resulted in favorable clinical outcomes and an acceptable toxicity profile in comparison with historic controls and warrants further investigation in a larger prospective study.

Evidence supports significant interactions among microbes, immune cells, and tumor cells in at least 10%-20% of human cancers, emphasizing the importance of further investigating these complex relationships. However, the implications and significance of tumor-related microbes remain largely unknown. Studies have demonstrated the critical roles of host microbes in cancer prevention and treatment responses. Understanding interactions between host microbes and cancer can drive cancer diagnosis and microbial therapeutics (bugs as drugs). Computational identification of cancer-specific microbes and their associations is still challenging due to the high dimensionality and high sparsity of intratumoral microbiome data, which requires large datasets containing sufficient event observations to identify relationships, and the interactions within microbial communities, the heterogeneity in microbial composition, and other confounding effects that can lead to spurious associations. To solve these issues, we present a bioinformatics tool, microbial graph attention (MEGA), to identify the microbes most strongly associated with 12 cancer types. We demonstrate its utility on a dataset from a consortium of nine cancer centers in the Oncology Research Information Exchange Network. This package has three unique features: species-sample relations are represented in a heterogeneous graph and learned by a graph attention network; it incorporates metabolic and phylogenetic information to reflect intricate relationships within microbial communities; and it provides multiple functionalities for association interpretations and visualizations. We analyzed 2,704 tumor RNA sequencing samples and MEGA interpreted the tissue-resident microbial signatures of each of 12 cancer types. MEGA can effectively identify cancer-associated microbial signatures and refine their interactions with tumors., Significance: Studying the tumor microbiome in high-throughput sequencing data is challenging because of the extremely sparse data matrices, heterogeneity, and high likelihood of contamination. We present a new deep learning tool, MEGA, to refine the organisms that interact with tumors., (© 2024 The Authors; Published by the American Association for Cancer Research.)

Aim: Real-world treatment patterns in tenosynovial giant cell tumor (TGCT) patients remain unknown. Pexidartinib is the only US FDA-approved treatment for TGCT associated with severe morbidity or functional limitations and not amenable to improvement with surgery. Objective: To characterize drug utilization and treatment patterns in TGCT patients. Methods: In a retrospective observational study using IQVIA's linked prescription and medical claims databases (2018-2021), TGCT patients were stratified by their earliest systemic therapy claim (pexidartinib [N = 82] or non-FDA-approved systemic therapy [N = 263]). Results: TGCT patients treated with pexidartinib versus non-FDA-approved systemic therapies were predominantly female (61 vs 50.6%) and their median age was 47 and 54 years, respectively. Pexidartinib-treated patients had the highest 12-month probability of remaining on treatment (54%); 34.1% of pexidartinib users had dose reduction after their first claim. Conclusion: This study provides new insights into the unmet need, utilization and treatment patterns of systemic therapies for the treatment of TGCT patients.

Background: Retroperitoneal liposarcomas are locally aggressive and frequently recur following complete surgical resection. Palbociclib, a cyclin-dependent kinase (CDK) 4/CDK6 inhibitor, is effective in the treatment of metastatic or unresectable liposarcoma., Objective: The purpose of this study was to describe our initial experience using adjuvant palbociclib to delay recurrence., Methods: Patients with resected RPS were identified from a prospectively maintained institutional database. In 2017, we began offering adjuvant palbociclib to patients following complete gross resection. Treatment interval, defined as the time between surgical resection and re-resection or change in systemic therapy, was compared between patients selected for adjuvant palbociclib or observation., Results: Between 2017 and 2020, 12 patients underwent a total of 14 operations (14 patient cases) and were selected for adjuvant palbociclib for recurrence prevention. These patients were compared with 14 patients who, since 2010, underwent a total of 20 operations (20 patient cases) and were selected for observation. Histology was primarily dedifferentiated liposarcoma for both groups (observation: 70% [14/20]; adjuvant palbociclib: 64% [9/14]). All patients underwent complete gross resection. Neither age, number of previous surgeries, histologic grade, or Eastern Cooperative Oncology Group (ECOG) performance status differed between groups (p > 0.05 for all). Patients selected for adjuvant palbociclib experienced a longer treatment interval than those selected for observation, although it did not reach statistical significance (20.5 months vs. 13.1 months, p = 0.08, log rank)., Conclusion: Adjuvant palbociclib may be associated with a prolonged interval between liposarcoma resection and the need for re-resection or other systemic therapy. Palbociclib may be effective in delaying liposarcoma recurrence, and its use for this indication warrants prospective study., (© 2023. Society of Surgical Oncology.)

Introduction: Patients treated with immune checkpoint inhibitors (ICIs) may not response to treatment and are at risk for immune-related adverse events (irAEs). Platelet function has been linked to both oncogenesis and immune evasion. We studied the association between the change in mean platelet volume (MPV), platelet count, survival, and the risk of developing irAEs in patients with metastatic non-small cell lung cancer (NSCLC) who have received first-line ICI., Methods: In this retrospective study, delta (∆) MPV was defined as the difference between cycle 2 and baseline MPV. Patient data were collected via chart review, and Cox proportional hazard and Kaplan-Meier method were used to assess the risk and estimate median overall survival., Results: We identified 188 patients treated with first-line pembrolizumab, with or without concurrent chemotherapy. There were 80 (42.6%) patients received pembrolizumab monotherapy, and 108 (57.4%) received pembrolizumab in combination with platinum-based chemotherapy. Patients whose MPV (∆MPV ≤ 0) decreased had hazard ratio (HR) = 0.64 (95% CI 0.43-0.94) for death with p = 0.023. Patients with ∆MPV ≤ - 0.2 fL (median), there was a 58% increase in the risk of developing irAE (HR = 1.58, 95% CI 1.04-2.40, p = 0.031). Thrombocytosis at baseline and cycle 2 was associated with shorter OS with p = 0.014 and 0.039, respectively., Conclusion: Change in MPV after 1 cycle of pembrolizumab-based treatment was significantly associated with overall survival as well as the occurrence of irAEs in patients with metastatic NSCLC in the first-line setting. In addition, thrombocytosis was associated with poor survival., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Ewing sarcoma (ES) is a rare, aggressive malignancy that typically arises from bone and is seen more in adolescents and young adults. In contrast, extraskeletal Ewing sarcoma (EES) is more prevalent in adults and women [1,2]. There is no standard treatment for extraskeletal tumors, especially those in sensitive areas, such as the vagina, where resection may cause a large cosmetic or functional deformity. This case features a woman in her 20s who presented with painless vaginal bleeding and was found to have a 4 × 5 × 4-mm EES of the posterior vaginal wall. The presentation raised both reproductive and functional concerns, as the patient was young, sexually active and of childbearing age. The patient underwent treatment with radiation therapy and chemotherapy every 3 weeks. Given the lack of guidance and proclivity of EES to metastasize, it is paramount to proceed with standard-of-care treatment even if it is small and there is a lack of metastatic disease. For women with vaginal EES who are of childbearing age, brachytherapy rather than surgical resection may be a more favorable option when considering the location and the potential impact of vaginectomy., (© 2023 The Authors.)

Emerging evidence supports the important role of the tumor microbiome in oncogenesis, cancer immune phenotype, cancer progression, and treatment outcomes in many malignancies. In this study, we investigated the metastatic melanoma tumor microbiome and potential roles in association with clinical outcomes, such as survival, in patients with metastatic disease treated with immune checkpoint inhibitors (ICIs). Baseline tumor samples were collected from 71 patients with metastatic melanoma before treatment with ICIs. Bulk RNA-seq was conducted on the formalin-fixed paraffin-embedded (FFPE) tumor samples. Durable clinical benefit (primary clinical endpoint) following ICIs was defined as overall survival ≥24 months and no change to the primary drug regimen (responders). We processed RNA-seq reads to carefully identify exogenous sequences using the {exotic} tool. The 71 patients with metastatic melanoma ranged in age from 24 to 83 years, 59% were male, and 55% survived >24 months following the initiation of ICI treatment. Exogenous taxa were identified in the tumor RNA-seq, including bacteria, fungi, and viruses. We found differences in gene expression and microbe abundances in immunotherapy responsive versus non-responsive tumors. Responders showed significant enrichment of several microbes including Fusobacterium nucleatum, and non-responders showed enrichment of fungi, as well as several bacteria. These microbes correlated with immune-related gene expression signatures. Finally, we found that models for predicting prolonged survival with immunotherapy using both microbe abundances and gene expression outperformed models using either dataset alone. Our findings warrant further investigation and potentially support therapeutic strategies to modify the tumor microbiome in order to improve treatment outcomes with ICIs., Competing Interests: Conflicts of Interest AAT: Contracted research grants with institution from Bristol Myers Squib, Genentech-Roche, Regeneron, Sanofi-Genzyme, Nektar, Clinigen, Merck, Acrotech, Pfizer, Checkmate, OncoSec.

Soft-tissue sarcomas (STS) are a rare and heterogeneous group of malignant tumors that arise from the oncogenic transformation of mesenchymal tissue. There are over 100 distinct STS histological and molecular subtypes with unique clinical, therapeutic, and prognostic features with variable responses to therapy regimens. Given the quality-of-life concerns and limited efficacy with current regimens, including cytotoxic chemotherapy, there is a need for novel therapies and regimens to treat advanced STS. Although immune checkpoint inhibitors have demonstrated significant improvements in survival outcomes in other cancer types, there remains ambiguous data on the impact of immunotherapy in sarcoma. Biomarkers like PD-1/PD-L1 are not always predictive of outcomes. Therefore, researching emerging novel therapies, such as CAR-T and adoptive cell therapies, is critical to understanding STS biology, STS tumor immune microenvironment immunomodulatory strategies that improve immune response, and survival outcomes. We discuss the underlying biology of the STS tumor immune microenvironment, immunomodulatory strategies that augment pre-existing immune responses, and novel approaches to develop sarcoma-specific antigen-based therapies., (© The Author(s) 2023.
