RESUMO

BACKGROUND: LCP1 encodes L-plastin, an actin-bundling protein primarily expressed in hematopoietic cells. In mouse and fish models, LCP1 deficiency has been shown to result in hematological and immune defects. OBJECTIVE: To determine the nature of a human inborn error of immunity resulting from a novel genetic variant of LCP1. METHODS: We performed genetic, protein and cellular analysis of PBMCs from a kindred with apparent autosomal dominant immune deficiency. We identified a candidate causal mutation in LCP1, which we evaluated by engineering the orthologous mutation in mice and Jurkat cells. RESULTS: A splice-site variant in LCP1 segregated with lymphopenia, neutropenia, and thrombocytopenia. The splicing defect results in at least two aberrant transcripts, producing an in-frame deletion of 24 nucleotides, and a frameshifting deletion of exon 8. Cellular analysis of the kindred revealed a proportionate reduction of T and B cells, and a mild expansion of transitional B cells. Similarly, mice carrying the orthologous genetic variant exhibited the same in-frame aberrant transcript, reduced expression Lcp1 and gene dose-dependent leukopenia, mild thrombocytopenia, and lymphopenia, with a significant reduction of T cell populations. Functional analysis revealed that LCP1c740-1G>A confers a defect in platelet development and function with aberrant spreading on collagen. Immunological analysis revealed defective actin organisation in T cells, reduced migration of PBMCs from patients, splenocytes from mutant mice, and a mutant Jurkat cell line in response to CXCL12, impaired germinal centre B cell expansion after immunisation, and reduced cytokinesis during T cell proliferation. CONCLUSION: We describe a unique human hematopoietic defect affecting neutrophils, lymphocytes and platelets, arising from partial LCP1 deficiency.

RESUMO

OBJECTIVE: Direct-acting antivirals for the treatment of hepatitis C virus (HCV) represented a paradigm shift. In 2017, sofosbuvir/velpatasvir (SOF/VEL-Epclusa®) was approved, which showed a high cure rate in all patient, contributing to HCV elimination. The analysis aimed to quantify the clinical and economic value of SOF/VEL in HCV chronic patients since its approval in Spain. METHODS: An economic evaluation was elaborated adapting a Markov model that simulated the lifetime disease progression in of all HCV chronic patients treated with SOF/VEL (30,488 patients) since its launch (5-years), compared to previous therapies. Patients entered the model and were distributed between the fibrosis states (F0-to-F4) in treated and untreated. All patients (100%) were treated with SOF/VEL regardless of their fibrosis, and 49% with previous therapies in ≥F2. The average sustained viral response (SVR) rates 98.9% SOF/VEL versus 61.0% previous therapies. All parameters for the analysis were obtained from real-life data and literature. Only direct healthcare costs associated with disease management were included. The SOF/VEL value was measured as the number of hepatic complications avoided and their associated cost, and hepatic mortality compared to previous therapies. National Health System perspective and a 3% discount rate was applied. RESULTS: SOF/VEL decreased the number of liver complications, avoiding 92% decompensated cirrhosis, 80% hepatocellular carcinomas, and 87% liver transplants, as well as 85% liver-related mortality. Their cost associated was reduced, amounting to savings of 197M€. CONCLUSION: SOF/VEL adds relevant value to the HCV treatment, reducing the clinical and economic disease burden and contributing to HCV elimination in Spain.

RESUMO

BACKGROUND: Recombinant human bone morphogenetic protein 2 (rhBMP-2) and human bone marrow mesenchymal stromal cells (hBM-MSCs) have been thoroughly studied for research and translational bone regeneration purposes. rhBMP-2 induces bone formation in vivo, and hBM-MSCs are its target, bone-forming cells. In this article, we studied how rhBMP-2 drives the multilineage differentiation of hBM-MSCs both in vivo and in vitro. METHODS: rhBMP-2 and hBM-MSCs were tested in an in vivo subcutaneous implantation model to assess their ability to form mature bone and undergo multilineage differentiation. Then, the hBM-MSCs were treated in vitro with rhBMP-2 for short-term or long-term cell-culture periods, alone or in combination with osteogenic, adipogenic or chondrogenic media, aiming to determine the role of rhBMP-2 in these differentiation processes. RESULTS: The data indicate that hBM-MSCs respond to rhBMP-2 in the short term but fail to differentiate in long-term culture conditions; these cells overexpress the rhBMP-2 target genes DKK1, HEY-1 and SOST osteogenesis inhibitors. However, in combination with other differentiation signals, rhBMP-2 acts as a potentiator of multilineage differentiation, not only of osteogenesis but also of adipogenesis and chondrogenesis, both in vitro and in vivo. CONCLUSIONS: Altogether, our data indicate that rhBMP-2 alone is unable to induce in vitro osteogenic terminal differentiation of hBM-MSCs, but synergizes with other signals to potentiate multiple differentiation phenotypes. Therefore, rhBMP-2 triggers on hBM-MSCs different specific phenotype differentiation depending on the signalling environment.

RESUMO

BACKGROUND: Glioblastoma (GBM) commonly displays epidermal growth factor receptor (EGFR) alterations (mainly amplification and EGFRvIII) and TAT-Cx43266-283 is a Src-inhibitory peptide with antitumor properties in preclinical GBM models. Given the link between EGFR and Src, the aim of this study was to explore the role of EGFR in the antitumor effects of TAT-Cx43266-283. METHODS: The effect of TAT-Cx43266-283, temozolomide (TMZ) and erlotinib (EGFR inhibitor) was studied in patient-derived GBM stem cells (GSCs) and murine neural stem cells (NSCs) with and without EGFR alterations, in vitro and in vivo. EGFR alterations were analyzed by Western blot (WB) and Fluorescence In Situ Hybridization (FISH) in these cells, and compared with Src activity and survival in GBM samples from TCGA. RESULTS: The effect of TAT-Cx43266-283 correlated with EGFR alterations in a set of patient-derived GSCs and was stronger than that exerted by TMZ and erlotinib. In fact, TAT-Cx43266-283 only affected NSCs with EGFR alterations, but not healthy NSCs. EGFR alterations correlated with Src activity and poor survival in GBM patients. Finally, tumors generated from NSCs with EGFR alterations, showed a decrease in growth, invasiveness and vascularization after treatment with TAT-Cx43266-283, which enhanced the survival of immunocompetent mice. CONCLUSION: Clinically relevant EGFR alterations are predictors of TAT-Cx43266-283 response and part of its mechanism of action, even in TMZ- and erlotinib-resistant GSCs. TAT-Cx43266-283 targets NSCs with GBM-driver mutations, including EGFR alterations, in an immunocompetent GBM model in vivo, suggesting a promising effect on GBM recurrence. Together, this study represents an important step towards the clinical application of TAT-Cx43266-283.

RESUMO

PURPOSE: Human immunodeficiency virus (HIV) burden among Florida adolescents and young adults (AYA, aged 13-24 years), particularly in Tampa Bay, is among the highest in the nation. We sought to determine the association between zip code-level test site accessibility and AYA HIV burden, compare this association with adult (aged 25-44 years) HIV burden, and identify local AYA HIV testing deserts. We further aimed to identify the association between test site accessibility and population-level markers of social disadvantage. METHODS: We geocoded HIV test sites and determined the percent surface area per zip code within 15-minute walking distance to ≥ 1 test sites (PSA15) in Pinellas and Hillsborough counties. We calculated Pearson's correlation coefficients for the association of PSA15 and HIV burden by age group and, separately, the association of PSA15 and population-level characteristics. RESULTS: Of the 96 zip codes analyzed, 36.5% had a PSA15 for HIV testing of 0%. The association between PSA15 and HIV burden was substantially higher for adults (r = 0.51, p < .001) than for AYA (r = 0.09, p = .38). Overall, we identified four potential AYA testing deserts. We also found that greater PSA15 was correlated with greater %Black/African-American residents (r = 0.32, p = .002), greater %residents living in poverty (r = 0.27, p = .008), and lower child opportunity index scores (r = -0.29, p = .004). DISCUSSION: Walking-accessible HIV test sites in Tampa Bay were limited and geographically distributed largely based on adult HIV burden, population-level markers of social disadvantage, and among areas with higher percentages of Black/African-American residents. Test site distribution was less correlated with AYA HIV burden, leaving this population vulnerable across multiple testing deserts.

RESUMO

In cancer patients, psychological distress, which encompasses anxiety, depression, and somatization, arises from the complex interplay of emotional and behavioral reactions to the diagnosis and treatment, significantly influencing their functionality and quality of life. The aim was to investigate factors associated with psychological distress in cancer patients. This prospective and multicenter study, conducted by the Spanish Society of Medical Oncology (SEOM), included two cohorts of patients with cancer (localized resected or advanced unresectable). They completed surveys assessing psychological distress (BSI-18) before and after cancer treatment and coping (MINI-MAC) and spirituality (FACIT-sp) prior to therapy. A multivariable logistic regression analysis and a Structural Equation Modeling (SEM) were conducted. Between 2019 and 2022, 1807 patients were evaluated, mostly women (54%), average age 64 years. The most frequent cancers were colorectal (30%), breast (25%) and lung (18%). Men had lower levels of anxiety and depression (OR 0.66, 95% CI 0.52-0.84; OR 0.72, 95% CI 0.56-0.93). Colorectal cancer patients experienced less anxiety (OR 0.63, 95% CI 0.43-0.92), depression (OR 0.55, 95% CI 0.37-0.81), and somatization (OR 0.59, 95% CI 0.42-0.83). Patients with localized cancer and spiritual beliefs had reduced psychological distress, whereas those with anxious preoccupation had higher level. SEM revealed a relationship between psychological distress and coping strategies, emphasizing how baseline anxious preoccupation exacerbates post-treatment distress. This study suggests that age, sex, extension and location of cancer, coping and spirituality influence psychological distress in cancer patients.

RESUMO

BACKGROUND: The optimal chemotherapy backbone for HER2-negative advanced esophagogastric cancer, either in combination with targeted therapies or as a comparator in clinical trials, is uncertain. The subtle yet crucial differences in platinum-based regimens' safety and synergy with combination treatments need consideration. METHODS: We analyzed cases from the AGAMENON-SEOM Spanish registry of HER2-negative advanced esophagogastric adenocarcinoma treated with platinum and fluoropyrimidine from 2008 to 2021. This study focused exclusively on patients receiving one of the four regimens: FOLFOX (5-FU and oxaliplatin), CAPOX (capecitabine and oxaliplatin), CP (capecitabine and cisplatin) and FP (5-FU and cisplatin). The aim was to determine the most effective and tolerable platinum and fluoropyrimidine-based chemotherapy regimen and to identify any prognostic factors. RESULTS: Among 1293 patients, 36% received either FOLFOX (n = 468) or CAPOX (n = 466), 20% CP (n = 252), and 8% FP (n = 107). FOLFOX significantly increased PFS (progression free survival) compared to CP, with a hazard ratio of 0.73 (95% CI 0.58-0.92, p = 0.009). The duration of treatment was similar across all groups. Survival outcomes among regimens were similar, but analysis revealed worse ECOG-PS (Eastern Cooperative Oncology Group-Performance Status), > 2 metastatic sites, bone metastases, hypoalbuminemia, higher NLR (neutrophil-to-lymphocyte ratio), and CP regimen as predictors of poor PFS. Fatigue was common in all treatments, with the highest incidence in FOLFOX (77%), followed by FP (72%), CAPOX (68%), and CP (60%). Other notable toxicities included neuropathy (FOLFOX 69%, CAPOX 62%), neutropenia (FOLFOX 52%, FP 55%), hand-foot syndrome in CP (46%), and thromboembolic events (FP 12%, CP 11%). CONCLUSIONS: FOLFOX shown better PFS than CP. Adverse effects varied: neuropathy was more common with oxaliplatin, while thromboembolism was more frequent with cisplatin.

RESUMO

BACKGROUND: The aim of this study was to evaluate the psychometric properties, differential item functioning, factorial invariance, and convergent validity of the Spanish version of the Herth Hope Index (HHI) in patients with cancer. METHOD: Exploratory and confirmatory factor analyses were conducted to explore the scale, dimensionality, functioning of items, test for strong measurement invariance across sex, age, tumor site, and expected survival, and an extended structural equation model to assess external validity in a cross-sectional, multicenter, prospective study of 863 cancer patients from 15 Spanish hospitals. RESULTS: The results do not support the original 3-factor scale but instead suggest a one-factor structure, which explained 62% of the common variance. Scores from the unidimensional structure exhibited satisfactory reliability (ω = .88). A strong invariance solution demonstrated excellent fit across sex, age, tumor site, and survival. HHI exhibited substantial associations with resilience coping strategies and spiritual well-being. CONCLUSIONS: The findings of our study contribute to the diversity of earlier empirical findings regarding the construct of hope. Despite this, our results indicate that the Spanish version of the HHI is a short, easy-to-administer, valid, reliable tool for evaluating cancer patients' levels of hope.

RESUMO

OBJECTIVES: Communication regarding prognosis to patients with advanced cancer is fundamental for informed medical decision making. Our objective was to analyse (1) the proportion of subjects with advanced cancer who prefer to know their prognosis, (2) the characteristics associated with patients' preference for prognostic information, (3) the psychological factors that impact the preference to know prognosis and 4) the concordance between preference for prognostic information perceived among physicians and patients. METHODS: A prospective, cross-sectional design was adopted. Data were collected from 748 participants with advanced cancer at 15 tertiary hospitals in Spain. Participants completed the following questionnaires: Mental Adjustment to Cancer; Trust in the Physician; Uncertainty in Illness Scale Patient's Prognostic Preferences. RESULTS: Fifty-two per cent of advanced cancer sufferers preferred to know the prognosis of their disease. Compared with participants who preferred not to know, those who did reported more uncertainty, greater satisfaction with their physician and higher scores on positive attitude (all p=0.001). Thirty-seven per cent of the physicians believed that patients want to know their prognosis, indicating that they underestimate the number of such patients. No significant differences were found regarding preference to know prognosis as a function of sociodemographic and clinical variables. CONCLUSIONS: A substantial proportion of individuals with advanced cancer prefer to know the prognosis of their disease. It appears that knowing their prognosis was mainly motivated by a need to maintain a positive attitude, lessen uncertainty and by satisfaction with the physician. It is important to explore patients' preferences for information to offer more personalised communication.

RESUMO

En las últimas décadas, las imágenes fotoacústicas han demostrado su eficacia en el apoyo al diagnóstico de algunas enfermedades, así como en la investigación médica, ya que a través de ellas es posible obtener información del cuerpo humano con características específicas y profundidad de penetración, desde 1 cm hasta 6 cm dependiendo en gran medida del tejido estudiado, además de una buena resolución. Las imágenes fotoacústicas son comparativamente jóvenes y emergentes y prometen mediciones en tiempo real, con procedimientos no invasivos y libres de radiación. Por otro lado, aplicar Deep Learning a imágenes fotoacústicas permite gestionar datos y transformarlos en información útil que genere conocimiento. Estas aplicaciones poseen ventajas únicas que facilitan la aplicación clínica. Se considera que con estas técnicas se pueden proporcionar diagnósticos médicos confiables. Es por eso que el objetivo de este artículo es proporcionar un panorama general de los casos donde se combina el Deep Learning con técnicas fotoacústicas.


In recent decades, photoacoustic imaging has proven its effectiveness in supporting the diagnosis of some diseases as well as in medical research, since through them it is possible to obtain information of the human body with specific characteristics and depth of penetration, from 1 cm to 6 cm depending largely on the tissue studied, in addition to a good resolution. Photoacoustic imaging is comparatively young and emerging and promises real-time measurements, with non-invasive and radiation-free procedures. On the other hand, applying Deep Learning to photoacoustic images allows managing data and transforming them into useful information that generates knowledge. These applications have unique advantages that facilitate clinical application. It may be possible with these techniques to provide reliable medical diagnoses. That is why the aim of this article is to provide an overview of cases combining Deep Learning with photoacoustic techniques.

RESUMO

Chronic hepatitis D (CHD) is a severe form of viral hepatitis that leads to liver cirrhosis and hepatocellular carcinoma. CHD is underdiagnosed, and this study aimed to assess the impact of hepatitis D reflex testing in HBsAg-positive individuals in Spain over the next 8 years. Two scenarios were compared: the current situation (7.6% of HBsAg-positive patients tested for anti-HDV) and reflex testing for all positive samples. A decision tree model was designed to simulate the CHD care cascade. Implementing reflex testing would increase anti-HDV detection to 5498 cases and HDV-RNA to 3225 cases. Additionally, 2128 more patients would receive treatment, with 213 achieving undetectable HDV-RNA levels. The cost per anti-HDV case detected would be €132. In the median time of the analysis, liver complications (decompensated cirrhosis, HCC and liver-related deaths) would be reduced by 35%-38%, implying an estimated cost savings of 36 million euros associated with the management of such complications. By 2030, implementing anti-HDV reflex testing would reduce the clinical and economic burden of CHD by 35%-38%.

RESUMO

INTRODUCTION: Given the growing interest and use of interleukin-17 inhibitors (anti-IL17) for the treatment of psoriatic arthritis (PsA), an observational study has been conducted to characterize the patient profile, treatment patterns, and persistence of ixekizumab or secukinumab in patients with PsA receiving them as first anti-IL17. METHODS: This is a multicenter retrospective study, conducted at eight Spanish hospitals where data from adult patients with PsA were collected from electronic medical records. Three cohorts of patients, initiating treatment with an anti-IL17 [secukinumab 150 mg (SECU150), secukinumab 300 mg (SECU300), or ixekizumab (IXE)] between January 2019 and March 2021, were included. Demographic and clinical patient characteristics, treatment patterns, and persistence were analyzed descriptively. Continuous data were presented as mean [standard deviation (SD)] and categorical variables as frequencies with percentages. Persistence rates at 3, 6, and 12 months were calculated. RESULTS: A total of 221 patients with PsA were included in the study [SECU150, 103 (46.6%); SECU300, 38 (17.2%); and IXE, 80 (36.2%)]. Treatment patterns differed by clinical characteristics: SECU150 was initiated more frequently in patients with moderate PsA and less peripheral joint involvement, while patients on SECU300 included those with a higher rate of enthesitis and active skin psoriasis, and patients on IXE showed a longer time since PsA diagnosis, more frequent comorbidities, joint involvement, and diagnosed skin psoriasis. Conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) were previously administered in 88.2% of patients and biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) were administered in 72.9%. The mean number of previous b/tsDMARDs was 2.4 (SD 1.5) in the IXE cohort, 1.7 (SD 0.9) in the SECU300 cohort, and 1.6 (SD 1.0) for those in the SECU150 cohort. The global persistence on all anti-IL17 was 97.2%, 88.4%, and 81.0% at 3, 6, and 12 months, respectively. The most frequent reason for discontinuation across the three cohorts was lack of effectiveness (16.7%; 37/221). CONCLUSIONS: Most of the patients with PsA treated with anti-IL17 in Spain had moderate to severe disease activity, high peripheral joint and skin involvement, and had received previous b/tsDMARDs. More than 80% of patients with a 1-year follow-up persisted on anti-IL17, with the highest rate observed in the IXE cohort, followed by the SECU150 then SECU300 cohorts.

RESUMO

The purpose of the study was to compare curability expectations between clinicians and patients and examine the influence of sociodemographic and clinical variables on these expectations and satisfaction within the clinician-patient relationship. This prospective study, conducted from February 2020 to May 2023, involved 986 advanced cancer patients. The patients completed questionnaires assessing treatment efficacy and toxicity predictions and the Scale to Assess the Therapeutic Relationship (STAR). Seventy-four percent of advanced cancer patients had an inaccurate perception of treatment curability. Clinicians perceived male patients with lung or digestive cancer without adenocarcinoma at locally advanced stages, with fewer comorbidities and better functional status (ECOG), as having higher curability expectations. Clinicians tended to have more realistic expectations than patients, since they had to consider the presence of treatment's side effects, while patients underestimated the possibility of experiencing these adverse effects. Patients who had more favorable expectations regarding survival and quality of life were found to be more satisfied with the care provided by their oncologists. It is crucial for patients to understand the treatment goals and establish realistic expectations in order to actively participate in decision-making and achieve a better quality of life at the end of life.

RESUMO

INTRODUCTION: Cardiac myxomas account for 50% of all benign cardiac tumors. Their clinical presentation varies from embolisms to fever. Our objective was to describe the surgical experience in the resection of cardiac myxomas during an 8-year period. METHODS: This is a retrospective, descriptive study of a series of cases with cardiac myxomas diagnosed from 2014 to 2022 at a tertiary care center. Descriptive statistics were used to define the populational and surgical characteristics. We used Pearson's correlation to study the relationship between postoperative complications and age, tumor size and affected cardiac chamber. RESULTS: 31 patients were included, with a predominance of females (1:2 ratio). The prevalence was 0.44%, which was calculated based on the number of cardiac surgeries performed in our unit over the 8-year period. The main clinical manifestation was dyspnea (85%, n = 23), followed by cerebrovascular event (CVE) (18%, n = 5). Atriotomy and resection of the pedicle were performed with preservation of the interatrial septum. Mortality was 3.2%. The postoperative evolution was uneventful in 77%. Tumor recurrence occurred in 2 patients (7%), both debuting with embolic phenomena. No association was observed between postoperative complications or recurrence and tumor size, nor aortic clamping and extracorporeal circulation times with regard to age. CONCLUSIONS: Four atrial myxoma resections are performed in our unit per year, with an estimated prevalence of 0.44%. The tumor characteristics described coincide with the previous literature. A relationship between embolisms and recurrences cannot be ruled out. Wide surgical resection of the pedicle and base of tumor implantation may influence tumor recurrence, although further studies are needed.

RESUMO

Financial difficulties experienced by cancer patients negatively impact the mental health of the patients. The objective of this study was to examine the mediating role of financial difficulties between physical symptoms and depression in patients with advanced cancer. A prospective, cross-sectional design was adopted in the study. The data were collected from 861 participants with advanced cancer in 15 different tertiary hospitals in Spain. The participants' socio-demographic characteristics were collected using a standardized self-report form. Hierarchical linear regression models were used to explore the mediating role of financial difficulties. In the results, 24% of patients reported a high level of financial difficulties. Physical symptoms were positively associated with financial difficulties and depression (ß = 0.46 and ß = 0.43, respectively), and financial difficulties was positively associated with depression (ß = 0.26). Additionally, financial difficulties played a role in explaining the relationship between physical symptoms and depression, showing a standardized regression coefficient of 0.43 which decreased to 0.39 after the financial difficulties were controlled. Healthcare professionals should consider the importance of providing financial resources and emotional support to help patients and their families cope with the financial burden associated with cancer treatment and its symptoms.

RESUMO

BACKGROUND: To examine whether financial stress during pregnancy mediates the association between maternal exposure to adverse childhood experiences (ACEs) and three birth outcomes (i.e., gestational age, birth weight, and admission to the neonatal intensive care unit [NICU]). METHODS: Data were obtained from a prospective cohort study of pregnant women and their infants in Florida and North Carolina. Mothers (n = 531; Mage at delivery = 29.8 years; 38% Black; 22% Hispanic) self-reported their exposure to childhood adversity and financial stress during pregnancy. Data on infant gestational age at birth, birth weight, and admission to the NICU were obtained from medical records within 7 days of delivery. Mediation analysis was used to test study hypotheses, adjusting for study cohort, maternal race, ethnicity, body mass index, and tobacco use during pregnancy. RESULTS: There was evidence of an indirect association between maternal exposure to childhood adversity and infant gestational age at birth (b = -0.03, 95% CI = -0.06 - -0.01) and infant birth weight (b = -8.85, 95% CI = -18.60 - -1.28) such that higher maternal ACE score was associated with earlier gestational age and lower infant birth weight through increases in financial distress during pregnancy. There was no evidence of an indirect association between maternal exposure to childhood adversity and infant NICU admission (b = 0.01, 95% CI = -0.02-0.08). CONCLUSIONS: Findings demonstrate one pathway linking maternal childhood adversity to a potentially preterm birth or shorter gestational age, in addition to low birth weight at delivery, and present an opportunity for targeted intervention to support expecting mothers who face financial stress.

RESUMO

Depressive symptoms are common in individuals with advanced cancer. OBJECTIVES: This study sought to analyze the relationship between physical and functional status and depressive symptoms, and to assess the role of mental adjustment across these variables in people with advanced cancer. METHODS: A prospective, cross-sectional design was adopted. Data were collected from 748 participants with advanced cancer at 15 tertiary hospitals in Spain. Participants completed self-report measures: Brief Symptom Inventory (BSI), Mini-Mental Adjustment to Cancer (Mini-MAC) scale, and the European Organization for Research and Treatment of Cancer (EORTC) questionnaire. RESULTS: Depression was present in 44.3% of the participants and was more common among women, patients <65 years old, non-partnered, and those with recurrent cancer. Results revealed a negative correlation with functional status, and functional status was negatively associated with depressive symptoms. Mental adjustment affected functional status and depression. Patients having a positive attitude displayed fewer depressive symptoms, while the presence of negative attitudes increased depressive symptoms in this population. CONCLUSIONS: Functional status and mental adjustment are key factors in the presence of depressive symptoms among people with advanced cancer. Assessment of functional status and mental adjustment should be considered when planning treatment and rehabilitation in this population.

RESUMO

PURPOSE: Patients with advanced cancer suffer significant decline of their psychological state. A rapid and reliable evaluation of this state is essential to detect and treat it and improve quality of life. The aim was to probe the usefulness of the emotional function (EF) subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EF-EORTC-QLQ-C30) to assess psychological distress in cancer patients. METHODS: This is a multicenter, prospective, observational study involving 15 Spanish hospitals. Patients diagnosed with unresectable advanced thoracic or colorectal cancer were included. Participants completed the Brief Symptom Inventory 18 (BSI-18), the current the gold standard, and the EF-EORTC-QLQ-C30 to assess their psychological distress prior to initiating systemic antineoplastic treatment. Accuracy, sensitivity, positive predictive value (PPV), specificity, and negative predictive value (NPV) were calculated. RESULTS: The sample comprised 639 patients: 283 with advanced thoracic cancer and 356 with advanced colorectal cancer. According to the BSI scale, 74% and 66% displayed psychological distress with an EF-EORTC-QLQ-C30 accuracy of 79% and 76% in detecting psychological distress in individuals with advanced thoracic and colorectal cancer, respectively. Sensitivity was 79 and 75% and specificity was 79 and 77% with a PPV of 92 and 86% and a NPV of 56 and 61% (scale cut-off point, 75) for patients with advanced thoracic and colorectal cancer, respectively. The mean AUC for thoracic cancer was 0.84 and, for colorectal cancer, it was 0.85. CONCLUSION: This study reveals that the EF-EORTC-QLQ-C30 subscale is a simple and effective tool for detecting psychological distress in people with advanced cancer.

RESUMO

PURPOSE: This study aimed to compare ramucirumab-paclitaxel versus chemotherapy in second-line (2L) advanced gastroesophageal cancer (aGEC) based on HER2 status and analyze prognostic factors. METHODS: The study includes patients from the AGAMENON-SEOM registry with aGEC and known HER2 status who received 2L between 2016 and 2021. The Kaplan-Meier method was used to calculate progression-free survival (PFS) and overall survival (OS) and multivariable Cox regression analysis was done to adjust for confounding variables. RESULTS: Of the 552 patients who met the selection criteria, 149 (26.9%) had HER2-positive aGEC, 89 were treated with chemotherapy, and 60 with ramucirumab-paclitaxel, and 403 had an HER2-negative aGEC, 259 were treated with chemotherapy, and 144 with ramucirumab-paclitaxel. In the whole sample, 2L PFS was 3.0 months (95% CI 2.8-3.2), 2L OS, 5.7 months (5.2-6.3), and ramucirumab-paclitaxel versus chemotherapy was associated with increased PFS (HR 0.64, 95% CI 0.53-0.78, p < 0.0001) and OS (HR 0.68, 0.55-0.83, p = 0.0002). Median PFS of ramucirumab- paclitaxel versus chemotherapy was 3.5 vs 2.8 months (HR 0.67, 0.54-0.83, p = 0.0004) in HER2-negative, and 4.7 vs 2.7 months (HR 0.57, 0.40-0.82, p = 0.0031) in HER2-positive aGEC, respectively. Median OS for ramucirumab-paclitaxel versus chemotherapy was 6.6 vs 5 months (HR 0.67, 0.53-0.85, p = 0.0007) in HER2-negative, and 7.4 vs 5.6 months (HR 0.70, 0.53-1.04, p = 0.083) in HER2-positive aGEC, respectively. ECOG-PS, tumor burden, Lauren subtype, and neutrophil-lymphocyte ratio were prognostic factors. CONCLUSIONS: In patients with an aGEC from the AGAMENON-SEOM registry, 2L treatment with ramucirumab-paclitaxel was superior to chemotherapy in PFS, OS and response rate, independent of HER2 status.

RESUMO

A cancer diagnosis can have a substantial impact on a patient's mental health and quality of life. The aim of this study was to investigate the prevalence of fatigue, emotional distress, and uncertainty and examine the predictive value they have on the quality of life of advanced cancer patients. A prospective, multicenter study was conducted between February 2020 and May 2021 of individuals diagnosed with an advanced, unresectable neoplasm prior to initiating systemic antineoplastic treatment. Participants completed questionnaires to quantify fatigue, emotional distress, disease uncertainty, and quality of life. A linear regression analysis was performed to study the predictive QoL variables. The study population comprised 508 patients, 53.7% of whom were male and had a mean age of 54.9 years. The most common cancers were digestive (40.6%), bronchopulmonary (29.1%), and breast (8.5%); the most frequent histology was adenocarcinoma (63%); and most were stage IV (79.7%). More than half (55.7%) suffered fatigue, and 47.7% exhibited emotional distress; both were more prevalent among women. Fatigue, emotional distress, and disease uncertainty all correlate with diminished quality of life. Similarly, ECOG performance status and the demographic variables of age, sex, and comorbidities impacted quality of life. This patient sample displayed a high prevalence of fatigue and emotional distress, together with illness uncertainty, which are clearly linked to waning quality of life. To decrease the experience of fatigue and improve mental health treatment in cancer patients, interventions based on a biopsychosocial model must be intensified.
