ABSTRACT
PURPOSE: The impact of age on optimal management of glioblastoma remains unclear. A recent combined analysis of two randomised trials, GEINO14-01 and EX-TEM, found no benefit from extending post-radiation temozolomide in newly diagnosed glioblastoma. Here, we explore the impact of age. METHODS: Relevant intergroup statistics were used to identify differences in tumour, treatment and outcome characteristics based on age with elderly patients (EP) defined as age 65 years and over. Survival was estimated using the Kaplan Meier method. RESULTS: Of the combined 205 patients, 57 (28%) were EP. Of these, 95% were ECOG 0-1 and 65% underwent macroscopic resection compared with 97% and 61% of younger patients (YP) respectively. There were numerically less MGMT-methylated (56% vs. 63%, p = 0.4) and IDH-mutated (4% vs. 13%, p = 0.1) tumours in EP vs. YP. Following surgery, EP were more likely to receive short course chemoradiation (17.5% vs. 6%, p = 0.017). At recurrence, EP tended to receive or best supportive care (28.3% vs. 15.4%, p = 0.09) or non-surgical options (96.2% vs. 84.6%, p = 0.06), but were less likely to receive bevacizumab (23.1% vs. 49.5%, p < 0.01). Median PFS was similar at 9.3months in EP and 8.5months in YP, with similar median OS at 20months. CONCLUSION: In this trial population of predominantly fit EP, survival was similar to YP despite a proportion receiving less aggressive therapy at diagnosis and recurrence. Advancing age does not appear to be an adverse prognostic factor for glioblastoma when patients are fit for treatment, and a less aggressive approach in selected patients may not compromise outcomes.

PURPOSE: The optimal duration of post-radiation temozolomide in newly diagnosed glioblastoma remains unclear, with no published phase III randomised trials. Standard-of-care stipulates 6 months. However, in routine care, it is often extended to 12 months, despite lacking robust supporting data. METHODS: GEINO14-01 (Spain) and EX-TEM (Australia) studies enrolled glioblastoma patients without progression at the end of 6 months post-radiation temozolomide. Participants were randomised 1:1 to six additional months of temozolomide or observation. Primary endpoint was 6-month progression free survival from date of randomisation (6mPFS). Secondary endpoints included overall survival (OS) and toxicity. 204 patients were required to detect an improvement in 6mPFS from 50 to 60% (80% power). Neither study recruited sufficient patients. We performed a combined analysis of individual patient data. RESULTS: 205 patients were recruited: 159 in GEINO14-01 (2014-2018) and 46 in EX-TEM (2019-2022). Median follow-up was 20.0 and 14.5 months. Baseline characteristics were balanced. There was no significant improvement in 6mPFS (57.2% vs 64.0%, OR0.75, p = 0.4), nor across any subgroups, including MGMT methylated; PFS (HR0.92, p = 0.59, median 7.8 vs 9.7 months); or OS (HR1.03, p = 0.87, median 20.1 vs 19.4 months). During treatment extension, 64% experienced any grade adverse event, mainly fatigue and gastrointestinal (both 54%). Only a minority required treatment changes: 4.5% dose delay, 7.5% dose reduction, 1.5% temozolomide discontinuation. CONCLUSION: For glioblastoma patients, extending post-radiation temozolomide from 6 to 12 months is well tolerated but does not improve 6mPFS. We could not identify any subset that benefitted from extended treatment. Six months should remain standard-of-care.

Introducción: La actinomicosis pélvica ha sido descrita en la literatura como asociada al uso de dispositivos intrauterinos, pero no siempre guarda relación con ellos. Hallazgos clínicos: En este artículo describimos dos casos de abscesos pélvicos en dos pacientes con cirugías previas y endometriosis, sin antecedente de uso de DIU. Diagnóstico: En ambas pacientes se aisló Actinomyces turicensis en los cultivos de los abscesos, entre otros microorganismos, siendo diagnosticadas de actinomicosis pélvica. Tratamiento: Las dos pacientes precisaron de drenaje quirúrgico de los abscesos y tratamiento antibiótico durante el ingreso y, una vez que se les dio de alta, requirieron un tratamiento de mantenimiento durante meses con amoxicilina. Resultados: Las dos pacientes mostraron resolución del cuadro clínico, analítico y radiológico durante el seguimiento posterior. Conclusión: Hacemos especial hincapié en la importancia de sospechar y tratar esta infección a tiempo, para evitar cirugías agresivas, así como realizar un adecuado diagnóstico diferencial con otros procesos que pueden presentar síntomas similares.(AU)
Introduction: Pelvic actinomycosis has been described in the literature associated with the use of intrauterine devices, but it is not always related to them. Clinical findings: In this article we describe two cases of pelvic abscesses in two patients with previous surgeries and endometriosis, without a history of IUD use. Diagnosis: Actinomyces turicensis was isolated in both patients in abscess cultures, among other microorganisms, being diagnosed with pelvic actinomycosis. Treatment: The two patients required surgical drainage of the abscesses and antibiotic treatment during admission and once they were discharged, they required maintenance treatment for months with Amoxicillin. Results: Both showed resolution of the clinical, analytical and radiological features during the subsequent follow-up. Conclusion: We place special emphasis on the importance of suspecting and treating this infection in time, to avoid aggressive surgeries and to carry out an adequate differential diagnosis with other processes that can give similar symptoms.(AU)

BACKGROUND: Recipient hepatectomy during liver transplantation can be a challenging operation and can increase cold ischaemic time. The aim of this study is to assess factors associated with prolonged recipient hepatectomy. METHODS: From 2005 to 2015, 930 patients were submitted to liver transplantation in our hospital. Prolonged hepatectomy time was defined as operative time >180 min (from knife on skin to total hepatectomy). Patients undergoing early liver retransplantation and living donation were excluded. RESULTS: A total of 715 patients were included in our study. Median age at transplantation was 53 (18-70) years, and median BMI was 26.2 (16-40). Median hepatectomy time was 131 min. Prolonged hepatectomy time occurred in 89 (12.4%) patients. At univariate analysis, previous decompensated cirrhosis with variceal bleeding and/or ascites, higher BMI and previous abdominal surgery were associated with prolonged operating time. Higher surgeon experience and acute liver failure were associated with shorter hepatectomy time. At multivariate analysis, previous episodes of variceal bleeding (p = 0.027, OR 1.78), BMI > 27 (p = 0.01, OR 1.75), previous abdominal surgery (p = 0.04, OR 1.68) and surgeon experience (p = 0.007, OR 2.04) were independently associated with operating time. Prolonged hepatectomy time was significantly associated with cold and total ischaemic time and intraoperative bleeding (p < 0.001, p = 0.002 and p = 0.002, respectively). CONCLUSIONS: Recipient BMI, previous episodes of variceal bleeding, previous abdominal surgery and surgeon experience are independently associated with hepatectomy duration. These factors can be helpful to identify those patients with potentially prolonged hepatectomy time, and therefore, strategies can be put in place to optimize outcomes in this group of patients.

INTRODUCTION: Cancer and blood disorders in children are rare. The progressive improvement in survival over the last decades largely relies on the development of international academic clinical trials that gather the sufficient number of patients globally to elaborate solid conclusions and drive changes in clinical practice. The participation of Spain into large international academic trials has traditionally lagged behind of other European countries, mainly due to the burden of administrative tasks to open new studies, lack of financial support and limited research infrastructure in our hospitals. METHODS: The objective of ECLIM-SEHOP platform (Ensayos Clínicos Internacionales Multicéntricos-SEHOP) is to overcome these difficulties and position Spain among the European countries leading the advances in cancer and blood disorders, facilitate the access of our patients to novel diagnostic and therapeutic approaches and, most importantly, continue to improve survival and reducing long-term sequelae. ECLIM-SEHOP provides to the Spanish clinical investigators with the necessary infrastructural support to open and implement academic clinical trials and registries. RESULTS: In less than 3 years from its inception, the platform has provided support to 20 clinical trials and 8 observational studies, including 8 trials and 4 observational studies where the platform performs all trial-related tasks (integral support: trial setup, monitoring, etc.) with more than 150 patients recruited since 2017 to these studies. In this manuscript, we provide baseline metrics for academic clinical trial performance that permit future comparisons. CONCLUSIONS: ECLIM-SEHOP facilitates Spanish children and adolescents diagnosed with cancer and blood disorders to access state-of-the-art diagnostic and therapeutic strategies.

OBJETIVE: To evaluate long-term renal function and morbimortality in non-syndromic Wilms tumor (WT) survivors. METHODS: Retrospective study about WT patients treated in 1993-2017, according to SIOP protocols. Mortality, glomerular filtration rate (GFR), prevalence of hypertension and requirement of dialysis and renal transplant were evaluated. Chronic kidney disease (CKD) was defined as GFR <90 ml/min/1.73 m2. RESULTS: Thirty-nine children were treated in the 25 analyzed years. Median time of follow-up was 6 years (0.5-21 years). 48% (19 patients) debuted with stage I or II. Four cases had high-grade histo-logy. Mortality rate was 10%. GFR data were found in 37 patients. Chronic kidney disease (grade I-II) turned up in 6 patients (16%). No patient required renal replacement therapy or renal transplant. 16% of patients developed CKD in both unilateral and bilateral WT, (p>0.05); OR 1.04 (IC 95% 0.09-10.9). Identical results were obtained comparing patients treated with or without radiotherapy (16%). Children with stage I-III had CKD in 11% vs. 40% of patients with stage IV (p=0.12); OR 5.3 (IC 95% 0.61-45). None of them presented hypertension in addition. CONCLUSIONS: In the current study the prevalence of CKD was low but not negligible, although no patients required renal replacement therapy or renal transplant. Bilateral renal involvement and radiotherapy were not associated with CKD development. Metastatic disease determines a higher risk of CKD.
OBJETIVOS: Evaluar la función renal y la morbimortalidad a largo plazo, en supervivientes de tumor de Wilms (TW) no sindrómico. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con TW entre 1993-2017 tratados según protocolos SIOP. Evaluamos mortalidad, filtrado glomerular (FG), prevalencia de hipertensión arterial (HTA), necesidad de diálisis y trasplante renal. Se definió enfermedad renal crónica (ERC) como FG <90 ml/min/1,73 m2. RESULTADOS: En los 25 años analizados se trataron 39 pacientes con edad media diagnóstica de 3,6 años (0,3-11 años). Mediana de seguimiento 6 años (0,5-21 años). El 48% (19 pacientes) debutaron con estadio I o II. Cuatro pacientes presentaron histología de alto riesgo (10%). La mortalidad fue del 10%. El 16% (6 pacientes) desarrolló ERC (grados I-II). Ningún paciente precisó terapia renal sustitutoria (TRS) o trasplante. La presencia de ERC tanto en enfermedad unilateral como bilateral fue del 16%, p>0,05; OR 1,04 (IC 95% 0,09-10,9). Se obtuvieron idénticos resultados (16%) comparando pacientes que recibieron radioterapia frente a aquellos que no. Los pacientes en estadio I, II y III presentaron una prevalencia de ERC del 11% vs. 40% en estadio IV (p=0,12); OR 5,3 (IC 95% 0,61-45). Ningún paciente asoció HTA crónica. CONCLUSIONES: En el presente estudio la prevalencia de ERC en supervivientes de TW no sindrómico es baja pero no desdeñable, aunque ninguno precisó trasplante renal o TRS. La presencia de enfermedad bilateral y la radioterapia no se asociaron al desarrollo de ERC. La enfermedad metastásica condiciona un riesgo mayor de ERC.

BACKGROUND AND AIMS: In the context of the shortage of donors, adult living donor liver transplantation (aLDLT) represents a feasible alternative for patients within as well as beyond the Milan criteria. METHODS: From 2001, we performed 42 aLDLTs for hepatocellular carcinoma (HCC). Sixteen of the recipients were within the Milan criteria, whereas 26 fulfilled the Barcelona-Clinic Liver Cancer Group (BCLC) expanded criteria (1 tumor ≤7 cm, 5 tumors ≤3 cm, or tumors 3 ≤5 cm without macrovascular invasion or down-staging to Milan after loco-regional therapies). The objective of the current study was to compare the post-transplantation results of these two groups. RESULTS: Six Milan-in and 16 beyond Milan patients received neo-adjuvant loco-regional therapies. One Milan-in and nine patients from the beyond Milan group presented an explant histological stage beyond Milan. After a median follow-up of 64 months, 5- and 10-year overall survival rates were 60.2% and 51.6% in the Milan-in group and 78% and 65% in the beyond Milan group. Five- and 10-year disease-free survival rates were 64.5% and 55.3% in the Milan-in patients and 67.9% and 56.6% in the beyond Milan patients. Being beyond up-to-seven criteria in the histology of the explant was a significant factor for HCC recurrence. CONCLUSION: The use of aLDLT in patients with HCC within and beyond Milan but within the BCLC expanded criteria offers acceptable survival and recurrence rates. Therefore, we believe that its use in this scenario is justified.

BACKGROUND: The management of schizophrenia is evolving towards a more comprehensive model based on functional recovery. The concept of functional recovery goes beyond clinical remission and encompasses multiple aspects of the patient's life, making it difficult to settle on a definition and to develop reliable assessment criteria. In this consensus process based on a panel of experts in schizophrenia, we aimed to provide useful insights on functional recovery and its involvement in clinical practice and clinical research. METHODS: After a literature review of functional recovery in schizophrenia, a scientific committee of 8 members prepared a 75-item questionnaire, including 6 sections: (I) the concept of functional recovery (9 items), (II) assessment of functional recovery (23 items), (III) factors influencing functional recovery (16 items), (IV) psychosocial interventions and functional recovery (8 items), (V) pharmacological treatment and functional recovery (14 items), and (VI) the perspective of patients and their relatives on functional recovery (5 items). The questionnaire was sent to a panel of 53 experts, who rated each item on a 9-point Likert scale. Consensus was achieved in a 2-round Delphi dynamics, using the median (interquartile range) scores to consider consensus in either agreement (scores 7-9) or disagreement (scores 1-3). Items not achieving consensus in the first round were sent back to the experts for a second consideration. RESULTS: After the two recursive rounds, consensus was achieved in 64 items (85.3%): 61 items (81.3%) in agreement and 3 (4.0%) in disagreement, all of them from section II (assessment of functional recovery). Items not reaching consensus were related to the concepts of functional recovery (1 item, 1.3%), functional assessment (5 items, 6.7%), factors influencing functional recovery (3 items, 4.0%), and psychosocial interventions (2 items, 5.6%). CONCLUSIONS: Despite the lack of a well-defined concept of functional recovery, we identified a trend towards a common archetype of the definition and factors associated with functional recovery, as well as its applicability in clinical practice and clinical research.

Diffuse infiltrating low-grade gliomas include oligodendrogliomas and astrocytomas, and account for about 5% of all primary brain tumors. Treatment strategies for these low-grade gliomas in adults have recently changed. The 2016 World Health Organization (WHO) classification has updated the definition of these tumors to include their molecular characterization, including the presence of isocitrate dehydrogenase (IDH) mutation and 1p/19p codeletion. In this new classification, the histologic subtype of grade II-mixed oligoastrocytoma has also been eliminated. The precise optimal management of patients with low-grade glioma after resection remains to be determined. The risk-benefit ratio of adjuvant treatment must be weighed for each individual (AU)

ABSTRACT
The Compact Linear Collider (CLIC) is an option for a future [Formula: see text] collider operating at centre-of-mass energies up to [Formula: see text], providing sensitivity to a wide range of new physics phenomena and precision physics measurements at the energy frontier. This paper is the first comprehensive presentation of the Higgs physics reach of CLIC operating at three energy stages: [Formula: see text], 1.4 and [Formula: see text]. The initial stage of operation allows the study of Higgs boson production in Higgsstrahlung ([Formula: see text]) and [Formula: see text]-fusion ([Formula: see text]), resulting in precise measurements of the production cross sections, the Higgs total decay width [Formula: see text], and model-independent determinations of the Higgs couplings. Operation at [Formula: see text] provides high-statistics samples of Higgs bosons produced through [Formula: see text]-fusion, enabling tight constraints on the Higgs boson couplings. Studies of the rarer processes [Formula: see text] and [Formula: see text] allow measurements of the top Yukawa coupling and the Higgs boson self-coupling. This paper presents detailed studies of the precision achievable with Higgs measurements at CLIC and describes the interpretation of these measurements in a global fit.

Purpose: The treatment of recurrent high-grade gliomas (HGG) is controversial. There are different therapeutic schedules but without a clear orientation about which of them should be used in each clinical situation. In addition, when patients suffer a second recurrence or they have poor performance status, they are excluded from clinical trials, although second recurrences and poor performance status are indeed more and more real and common situations in the clinical setting. In this study, we assessed the efficacy and safety of fotemustine (FTM) in HGG [fundamentally, glioblastomas (GB)], independent of time of recurrence or performance status. Methods/patients: Retrospective study in HGG patients treated with FTM in second or further line according to standard, the Addeo or any other scheme, starting treatment prior to 30 November 2012. Included patients reflect the regular situation in which the drug is used in terms of comorbidities and analytic situation (hematologic, renal and hepatic functions). Response assessment was performed by MRI and according to the clinical protocols of each center (every 8-12 weeks). Clinical situation and supportive care drugs were evaluated in each medical consultation. Clinical end-points analyzed, among others, were: PFS-6, PFS, OS, response rates, toxicity, quality of life and neurocognitive impact. Results: In terms of activity, an overall response rate of 8 % was observed: partial response 6 % (7 patients) and complete response 2 % (2 patients). The median time to achieve the greater response with FTM was 73 days (4-841 days). Patients treated according to the Addeo schedule had a shorter time to greater response in comparison with other schedules (85.9 vs 114 days), although without statistical significance. There were no significant differences in progression-free survival (PFS) when comparing different FTM schedules or using FTM in first or second recurrence. Median PFS: 3 months. PFS-6: 30.3 %. Overall survival (OS): although without significant differences, a tendency to better survival when using the Addeo schedule versus other schedules was observed (at 6 months, 44.6 vs 34.5 %; at 12 months, 25 vs 23.6 %; at 18 months, 11.5 vs 7.9 %), as well as if earlier use (second vs third line) concerning OS-12 (33.7 vs 18.2 %). Median OS: 5.2 months. Grades 3-4 toxicity was 28 % (31 patients), being neutropenia (4 %) and thrombocytopenia (17 %) the most frequent adverse reactions. From quality of life and neuro-cognitive function perspectives, 11 patients (10 %) and 16 (14 %) improved the Karnofsky Index and neurological impairment, respectively, after FTM treatment. Conclusion: This study has shown that FTM is safe and has a comparable activity with other available therapeutic options of use in the treatment of recurrent HGG (AU)
