RESUMO
Once metastatic bladder cancer has progressed to first-line treatment, the number of therapeutic options is scarce. Among chemotherapeutic agents showing activity in phase II trials, including taxanes, vinflunine (VFL) is the only one shown to increase overall survival in a phase III trial. In addition to its efficacy, VFL is safe in special population groups. Despite this, the prognosis for these patients remains poor, and more effective therapies need to be developed. Agents acting on new therapeutic targets as well as biomarkers to aid matching patients to specific treatments are currently under evaluation. In this regard, immunotherapy is showing promising results. In this article, a critical review of current treatments and future prospects is made, and therapy recommendations are made based on existing scientific evidence.

OBJECTIVES: To analyze the nutritional management practices in Intensive Care (ICU) to detect the need for improvement actions. Re-evaluate the process after implementation of improvement actions. DESIGN: Prospective observational study in 3 phases: 1) observation; 2) analysis, proposal development and dissemination; 3) analysis of the implementation. SETTING: ICU of a hospital of high complexity. PARTICIPANTS: Adult ICU forecast more than 48h of artificial nutrition. PRIMARY ENDPOINTS: Parenteral nutrition (PN), enteral nutrition (EN) (type, average effective volume, complications) and average nutritional ratio. RESULTS: A total of 229 patients (phase 1: 110, phase 3: 119). After analyzing the initial results, were proposed: increased use and precocity of EN, increased protein intake, nutritional monitoring effectiveness and increased supplementary indication NP. The measures were broadcast at specific meetings. During phase 3 more patients received EN (55.5 vs. 78.2%, P=.001), with no significant difference in the start time (1.66 vs. 2.33 days), duration (6.82 vs. 10,12 days) or complications (37,7 vs. 47,3%).Use of hyperproteic diets was higher in phase 3 (0 vs. 13.01%, P<.05). The use of NP was similar (48.2 vs. 48,7%) with a tendency to a later onset in phase 3 (1.25±1.25 vs. 2.45±3.22 days). There were no significant differences in the average nutritional ratio (0.56±0.28 vs. 0.61±0.27, P=.56). CONCLUSIONS: The use of EN and the protein intake increased, without appreciating effects on other improvement measures. Other methods appear to be necessary for the proper implementation of improvement measures.

After progression during first-line treatment in advanced non-small-cell lung cancer (NSCLC), a large percentage of patients are candidates for second-line treatment. The majority do not have epidermal growth factor receptor-activating mutations (EGFRwt). This article reviews the treatment options available for this subpopulation of patients, which includes essentially docetaxel, pemetrexed and erlotinib. These drugs all have similar efficacy, both in terms of objective response rates and overall survival, although with different toxicity profiles. In view of the similar efficacy of the three agents (docetaxel, pemetrexed and erlotinib) in the second-line treatment of NSCLC in the EGFRwt population, and although there are no prospective studies on predictive variables or new molecular markers available, selection of the treatment will depend on the histological type (pemetrexed); patient preference (oral as opposed to intravenous formulation); the presence of comorbid conditions; quality of life; previous or residual toxicities; the risk of neutropenia; response to and the duration of the first-line chemotherapy; and history of smoking.

BACKGROUND: Cancer is a risk factor for developing severe COVID19. Additionally, SARS-CoV2 has a special tropism for renal cells and complications like thrombosis or cytokine storm could be enhanced by standard treatments in kidney cancer (i.e., antiangiogenics or immunotherapy). Thus, understanding the impact of COVID19 in patients with this tumor is key for their correct management. METHODS: We designed a retrospective case-control study comparing the outcome of three groups of advanced kidney cancer patients on systemic treatment: cohort A (developed COVID19 while on antiangiogenics), cohort B (developed COVID19 while on immunotherapy) and cohort C (non-infected). Matching factors were age, gender, and treatment. RESULTS: 95 patients were recruited in 16 centers in Spain from September 2020 to May 2021. Finally, 85 were deemed as eligible (23 cohort A, 21 cohort B, 41 cohort C). Patients with COVID required more dose interruptions (25 vs. six) and hospitalizations (10 vs. none) than those without COVID (both p = 0.001). No difference between cohorts A and B was observed regarding hospitalization or length of stay. No ICU admission was registered and one patient in cohort B died due to COVID19. Regarding cancer evolution, three patients in cohort A presented progressive disease after COVID19 compared to two in cohort B. One case in cohort B, initially deemed as stable disease, achieved a partial response after COVID19. CONCLUSIONS: Kidney cancer patients who developed COVID19 while on systemic therapy required more treatment interruptions and hospitalizations than those non-infected. However, no significant impact on cancer outcome was observed. Also, no difference was seen between cases on antiangiogenics or immunotherapy.

Introduction: Radium-223 dichloride (Ra-223) is recommended as a treatment option for metastatic castration-resistant prostate cancer (mCRPC) patients with symptomatic bone metastases and no visceral disease, after docetaxel failure, or in patients who are not candidates to receive it. In this study, we aimed to ambispectively analyze overall survival (OS) and prognostic features in mCRPC in patients receiving Ra-223 as per clinical routine practice and identify the most suitable treatment sequence. Patients and methods: This study is observational, multicentric, and ambispective. Eligibility criteria included mCRPC patients treated with Ra-223, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, without visceral metastases, and no more than three cm involved lymph nodes. Results: A total of 145 patients were included; the median age was 73.97 years, and a Gleason score of more than or equal to 7 in 61 (48%) patients; 73 (81%) had previously received docetaxel. The most important benefit was reached by those patients who received Ra-223 in the second-line setting, with a median OS of 17 months (95% CI, 12-21), and by patients who received six cycles of treatment, with a median OS of 19 months (95% CI, 14-21). An alkaline phosphatase (ALP) decrease was also identified as a prognosis marker. When performing the multivariate analysis, the time to develop castration-resistant disease longer than 24 months was the most important prognostic factor to predict the evolution of the patients receiving Ra-223. Ra-223 was well tolerated, with thrombocytopenia, anemia, and diarrhea being the main adverse events. Conclusion: There is a benefit for those patients who received Ra-223 in the second-line setting, regardless of prior use of docetaxel. In addition, a survival benefit for patients presenting with a decline in ALP was observed.
RESUMO
Introduction: Introduction: gastrocolic fistula is an infrequent but severe complication of percutaneous gastrostomy. Clinical suspicion in the presence of chronic diarrhea of unknown etiology manifesting after percutaneous radiological gastrostomy (PRG) tube replacement is key to early detection and treatment. Case report: we report the case of a patient with PRG that began with chronic diarrhea after tube replacement and developed severe malnutrition. Initial treatment was not effective, studies were extended with the finding of this complication in a CT image. The use of this tube was discontinued with resolution of diarrhea and a favorable nutritional outcome. Discussion: this case report shows the importance of considering gastrocolic fistula in the differential diagnosis of persistent diarrhea in a patient with a gastrostomy tube.
Introducción: Introducción: la fístula gastrocólica supone una complicación infrecuente pero potencialmente grave de las sondas de gastrostomía. La sospecha clínica ante una diarrea de origen incierto que comienza tras el recambio de la sonda es clave para la detección y el tratamiento precoces. Caso clínico: se presenta el caso de un paciente portador de gastrostomía radiológica percutánea (PRG) que comienza con diarrea persistente tras el primer recambio de la sonda y desnutrición grave secundaria. Tras el fracaso de las medidas terapéuticas iniciales se amplían los estudios, con hallazgo de esta complicación en la imagen de TC. Se suspende el uso de esta sonda con resolución de la diarrea y evolución nutricional favorable. Discusión: este caso pone de manifiesto la importancia de incluir la fístula gastrocólica en el diagnóstico diferencial de la diarrea persistente en un paciente portador de sonda de gastrostomía.

OBJECTIVE: The aim of this study is to describe the results of Spanish ICUs in ETHICUS II study. DESIGN: Planned substudy of patients from ETHICUS II study. SETTING: 12 Spanish ICU. PATIENTS OR PARTICIPANTS: Patients admitted to Spanish ICU who died or in whom a limitation of life-sustaining treatment (LLST) was decided during a recruitment period of 6 months. INTERVENTIONS: Follow-up of patients was performed until discharge from the ICU and 2 months after the decision of LLST or death. MAIN VARIABLES OF INTEREST: Demographic characteristics, clinical profile, type of decision of LLST, time and form in which it was adopted. Patients were classified into 4 categories according to the ETHICUS II study protocol: withholding or withdrawing life-sustaining therapy, active shortening of the dying process, failed cardiopulmonary resuscitation and patients with brain death. RESULTS: A total of 795 patients were analyzed; 129 patients died after CPR, 129 developed brain death. LLST was decided in 537 patients, 485 died in the ICU, 90.3%. The mean age was 66.19 years ± 14.36, 63.8% of male patients. In 221 (41%) it was decided to withdraw life-sustaining treatments and in 316 (59%) withholding life-sustaining treatments. Nineteen patients (2.38%) had advance living directives. CONCLUSIONS: The predominant clinical profile when LTSV was established was male patients over 65 years with mostly cardiovascular comorbidity. We observed that survival was higher in LLST decisions involving withholding of treatments compared to those in which withdrawal was decided. Spain has played a leading role in both patient and ICU recruitment participating in this worldwide multicenter study.

In recent years, a key issue in the management of patients with metastatic renal cell carcinoma (mRCC) has been the assessment of health-related quality of life (HRQoL), particularly following the introduction of targeted therapies that have brought significant improvements in progression-free survival and quality of life in these patients. HRQoL is becoming one of the main factors influencing choice of therapy, and HRQoL experienced during first-line treatment may affect the choice of the second-line therapy. Consequently, several trials have been conducted to evaluate the impact of approved targeted therapies for mRCC on HRQoL, and this measure is being introduced with increasing frequency in the trial design. With respect to agents used after progression on cytokines, sunitinib and temsirolimus have yielded better HRQoL scores, and sorafenib and pazopanib have shown stable HRQoL scores compared with placebo. Regarding targeted agents approved for patients who progress on a first-line tyrosine kinase inhibitor, everolimus has shown to delay and reduce the degree of Karnofsky performance status deterioration compared with placebo. Moreover, evidence obtained from these trials shows that tumor response and delay in disease progression affect HRQoL. In this article, we review the different HRQoL scales used to evaluate patients with mRCC along with the results obtained in clinical trials. Given that HRQoL is determined not only by treatment-related effects but also by mRCC symptoms and its clinical complications, the characteristics and appropriate treatment of the most commonly experienced symptoms, including anorexia, fatigue, pain, anemia, and venous thromboembolism, are also reviewed.

BACKGROUND: Personalized precision medicine represents a paradigm shift and a new reality for the health care system in Spain, with training being fundamental for its full implementation and application in clinical practice. In this sense, health care professionals face educational challenges related to the acquisition of competencies to perform their professional practice optimally and efficiently in this new environment. The definition of competencies for health care professionals provides a clear guide on the level of knowledge, skills, and attitudes required to adequately carry out their professional practice. In this context, this acquisition of competencies by health care professionals can be defined as a dynamic and longitudinal process by which they use knowledge, skills, attitudes, and good judgment associated with their profession to develop it effectively in all situations corresponding to their field of practice. OBJECTIVE: This report aims to define a proposal of essential knowledge domains and common competencies for all health care professionals, which are necessary to optimally develop their professional practice within the field of personalized precision medicine as a fundamental part of the medicine of the future. METHODS: Based on a benchmark analysis and the input and expertise provided by a multidisciplinary group of experts through interviews and workshops, a new competency framework that would guarantee the optimal performance of health care professionals was defined. As a basis for the development of this report, the most relevant national and international competency frameworks and training programs were analyzed to identify aspects that are having an impact on the application of personalized precision medicine and will be considered when developing professional competencies in the future. RESULTS: This report defines a framework made up of 58 competencies structured into 5 essential domains: determinants of health, biomedical informatics, practical applications, participatory health, and bioethics, along with a cross-cutting domain that impacts the overall performance of the competencies linked to each of the above domains. Likewise, 6 professional profiles to which this proposal of a competency framework is addressed were identified according to the area where they carry out their professional activity: health care, laboratory, digital health, community health, research, and management and planning. In addition, a classification is proposed by progressive levels of training that would be advisable to acquire for each competency according to the professional profile. CONCLUSIONS: This competency framework characterizes the knowledge, skills, and attitudes required by health care professionals for the practice of personalized precision medicine. Additionally, a classification by progressive levels of training is proposed for the 6 professional profiles identified according to their professional roles.

RESUMO
Broadly neutralizing antibodies (bnAbs) bind and neutralize diverse HIV isolates and demonstrate protective effects in primate models and humans against specific isolates. To develop an effective HIV vaccine, it is widely believed that inducing these antibodies is crucial. However, the high somatic hypermutation in bnAbs and the limited affinity of HIV Env proteins for bnAb germline precursors suggest that extended antigen exposure is necessary for their production. Consequently, HIV vaccine research is exploring complex sequential vaccination strategies to guide the immune response through maturation stages. In this context, the exploration of the factors linked to the generation of these antibodies across diverse age groups becomes critical. In this study, we assessed the anti-HIV-1 neutralization potency and breadth in 108 aviremic adults and 109 aviremic children under 15 years of age who were receiving ART. We used a previously described minipanel of recombinant viruses and investigated the factors associated with neutralization in these individuals. We identified individuals in both groups who were capable of neutralizing viruses from three different subtypes, with greater cross-neutralization observed in the adult group (49.0% vs. 9.2%). In both groups, we observed an inverse association between neutralization breadth and the CD4+/CD8+ ratio, as well as a direct association with the time to ART initiation. However, we found no association with time post-infection, cumulative ART duration, or CD8+ cell levels. The present study demonstrates that children receiving antiretroviral therapy generate broadly neutralizing responses to HIV-1, albeit with lower magnitude compared to adults. We also observed that neutralization breadth is associated with CD4+/CD8+ levels and time to treatment initiation in both children and adults living with HIV-1. Our interpretation of these results is that a delay in ART initiation could have prolonged the antigenic stimulation associated with viral replication and thus facilitate the capacity to elicit long-lasting broadly neutralizing responses. These results corroborate prior findings that show that HIV-1-neutralizing responses can persist for years, even at low antigen levels, implying an HIV-1 vaccine may induce lasting neutralizing antibody response.
RESUMO
BACKGROUND AND AIMS: The use of continuous glucose monitoring (CGM) has become standard practice in people with type 1 diabetes. The evaluation of user satisfaction is crucial. The Glucose Monitoring Experiences questionnaire (GME-Q) includes 23 items with a 5-point Likert scale to produce a total satisfaction score and three subscale scores. The study aimed to translate the GME-Q from English into Spanish and to validate its use in Spanish-speaking CGM users with type 1 diabetes. METHODS: The linguistic translation and validation process of the GME-Q was established. T1D CGM users were asked to complete the produced Spanish version of the GME-Q and interviewed about difficulties or misunderstandings. Total satisfaction, effectiveness, convenience and intrusiveness subscales and internal consistency reliability were computed. RESULTS: Forward and backward translations and cognitive debriefing produced a final version of the GME-Q in Spanish. Ninety-eight subjects with type 1 diabetes were selected (age: 40 ± 12 years, 63% females, Hb1c: 7.2 ± 0.9% (55 ± 10 mmol/l), pump users: 78%, CGM use: 3.7 ± 2.6 years). The completion rate was 99% and the Cronbach's alpha coefficient was 0.8. The total satisfaction score was 3.9 ± 0.4 (effectiveness: 4.1 ± 0.6, convenience: 3.8 ± 0.6, intrusiveness: 2.2 ± 0.7). CONCLUSION: The GME-Q was translated into Spanish and validated for Spanish-speaking CGM users with type 1 diabetes.

BACKGROUND: In clinical studies, first-line afatinib demonstrated efficacy in Del19-EGFR NSCLC. MATERIALS AND METHODS: This prospective, non-interventional study assessed efficacy and safety of first-line afatinib in patients with advanced/metastatic NSCLC with Del19-EGFR from Galicia (Spain), with a preplanned analysis by age (<70 vs ≥70 years). RESULTS: Median age of 46 patients enrolled was 69.5 years (range 37-87). The objective response rate (ORR) was 78.2%, with median progression-free survival (PFS) of 20.5 months (95% CI 12.7, 28.3) and median overall survival (OS) of 37.5 months (95% CI 19.2-55.8). Outcomes by age (<70 vs ≥70 years) were ORR of 82.6% vs 73.9%, median PFS of 20.2 months (95% CI 14.8-25.6) vs 24.1 (9.8-38.3), and median OS of 45.1 months (95% CI, 17.0-73.1) vs 33.9 (28.7-39.1), respectively. Median treatment duration was 17.2 months (range 0.4-64.1) with 11 patients still on treatment; 14 patients received osimertinib at discontinuation due to T790M. Grade 3 adverse events included mucositis (n = 7, 15.2%), skin toxicity (n = 9, 19.6%), and diarrhea (n = 6, 13.0%) that were manageable with dose reductions. The afatinib dose was reduced in 31 patients (67.4%) and treatment was discontinued in 8 patients (17.4%) due to adverse events. By age (<70 vs ≥70 years), afatinib was dose-reduced in 13 (56.5%) vs 18 patients (78.3%) and discontinued in 3 (13.0%) vs 5 patients (21.7%), respectively. CONCLUSIONS: PFS in our patients was longer than reported in clinical studies with similar response rates and toxicity, even in older patients, reflecting a good risk-benefit from afatinib in patients with Del19-EGFR NSCLC. MICROABSTRACT: This real-world study of first-line afatinib in Caucasian patients with Del19 EGFR NSCLC reported durable efficacy and showed that older patients (> 70 years) benefitted from afatinib as much as younger patients. The safety profile of afatinib was as expected, albeit more dose reductions in older patients. Afatinib may be an option for patients with Del19 EGFR NSCLC, even in those who are older.

Immunotherapy with Immune Checkpoint Inhibitors (ICIs) has demonstrated a profitable performance for Non-Small Cell Lung Cancer (NSCLC) cancer treatment in some patients; however, there is still a percentage of patients in whom immunotherapy does not provide the desired results regarding beneficial outcomes. Therefore, obtaining predictive biomarkers for ICI response will improve the treatment management in clinical practice. In this sense, liquid biopsy appears as a promising method to obtain samples in a minimally invasive and non-biased way. In spite of its evident potential, the use of these circulating biomarkers is still very limited in the real clinical practice, mainly due to the huge heterogeneity among the techniques, the lack of consensus, and the limited number of patients included in these previous studies. In this work, we review the pros and cons of the different proposed biomarkers, such as soluble PD-L1, circulating non-coding RNA, circulating immune cells, peripheral blood cytokines, and ctDNA, obtained from liquid biopsy to predict response to ICI treatment at baseline and to monitor changes in tumor and tumor microenvironment during the course of the treatment in NSCLC patients.
RESUMO
BACKGROUND: Maximum tolerated dose (MTD) chemotherapy followed by metronomic chemotherapy (low doses given on a frequent schedule) acts on tumour vascular endothelial cells by increasing the anti-tumour effect of anti-angiogenic agents. This multicentre, phase 2 study investigated the effectiveness of MTD gemcitabine combined with metronomic capecitabine plus the multikinase inhibitor sorafenib for the treatment of metastatic renal-cell carcinoma (RCC). METHODS: Patients were enrolled at eight centres across Spain between Dec 13, 2006, and April 17, 2008. Patients were aged 18 years or older, had confirmed metastatic RCC with clear-cell histology, had an Eastern Cooperative Oncology Group performance status of 0 or 1, had not undergone previous therapy, and were unsuitable for, or intolerant to, immunotherapy. Treatment consisted of intravenous gemcitabine 1000 mg/m(2) (days 1 and 8), oral capecitabine 500 mg/m(2) twice a day (final dose after adjustment, days 1-14), and oral sorafenib 400 mg twice a day (days 1-21), for six cycles, followed by sorafenib monotherapy (at the investigator's discretion if clinical benefit was maintained). The primary endpoint was median progression-free survival (PFS) analysed in a population of all patients who received treatment. The trial is registered with ClinicalTrials.gov, number NCT00496301. FINDINGS: 44 patients enrolled in the study, 40 of whom received treatment. Median PFS for these patients was 11.1 months (95% CI 7.9-17.1). A partial response was achieved in 20 patients, and stable disease in 17 patients. Most adverse events were grade 1 or 2. Grade 3 adverse events were fatigue or asthenia (n=9), hand-foot skin reaction (n=11), mucositis (n=3), diarrhoea (n=2), infection (n=2), and allergic reaction, hypertension, and rash (all n=1). Grade 3 haematological toxicity was noted in nine patients. One death due to pulmonary embolism was reported as grade 5 dyspnoea possibly related to study drug. INTERPRETATION: PFS and response rates were greater than those previously observed with gemcitabine and capecitabine or sorafenib monotherapy in patients with metastatic RCC. Adverse events were manageable in most patients. These findings provide preliminary confirmation of the synergistic activity of the chemo-switch concept seen in preclinical studies, and merit further exploration. FUNDING: Spanish Oncology Genitourinary Group (SOGUG).

AIM: To describe the clinical management and PD-L1 testing of patients with newly diagnosed stage IV non-small cell lung cancer (NSCLC) without driver mutations in Spain. METHODS: Multicenter, retrospective study. RESULTS: Among 297 evaluated patients, 89.2% received systemic treatment for stage IV disease, of whom 53.6% received platinum doublet therapy, 26.8% immunotherapy as monotherapy and 14.7% immunotherapy + chemotherapy, with 9.4% receiving treatment as part of a clinical trial. Treatment was initiated 1 month after histological diagnosis, with PD-L1 test results available in most cases (92.6%). PD-L1 testing was performed in 287 patients, 95.1% by in-house tests, mostly with the 22C3 pharmDx assay. The factor most strongly associated with treatment selection was, as expected, the expression of PD-L1. CONCLUSION: PD-L1 testing is implemented in clinical practice and seems to guide treatment decisions in patients with NSCLC in Spain.
RESUMO
BACKGROUND AND OBJECTIVES: Currently, the patient's baseline situation is a more important prognostic factor than age. The purpose of this study is to estimate the prognostic value of the ISAR score (Identification of Senior at Risk) in patients ≥75 years admitted to intensive care (ICU). PATIENTS AND METHODS: Prospective multicenter study including patients ≥75 years admitted to the ICU > 24hours. On admission, 28 days and 6 months after discharge from the ICU, mortality and baseline were evaluated using the ISAR score, the Lawton and Brody scale (LB) and the Barthel index (BI), the Frail fragility scale. scale (FS), the Charlson comorbidity index (ICC), Dementia rating score (DRC). RESULTS: 38 of 94 patients (40%) were high risk (ISAR ≥ 3) and were characterized by BI 90 (65-100), LB 4 (3-5), and CDR 1 (0-2), ICC 7.5 (6-10). 58% had FS ≥ 3. In the long term, they were in a situation of dependency [BI 50 (2.5-77.5), LB 3 (0-4), CDR 1 (0-1.5)]. The ICU mortality at 28 days and 6 months was 18.4%, 25.7% and 35.3%, respectively, being statistically significant. The area under the ISAR score ROC curve was 0.749 to 0.797, in all the mortality periods studied, although the difference with other predictive variables was not significant, but the p value was the lowest. CONCLUSIONS: The ISAR score predicts mortality in critically elderly patients with a discriminative capacity comparable to other predictive variables.

PURPOSE: Characterization of the T-cell receptor (TCR) repertoire may be a promising source for predictive biomarkers of pathologic response to immunotherapy in locally advanced non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN: In this study, next-generation TCR sequencing was performed in peripheral blood and tissue samples of 40 patients with NSCLC, before and after neoadjuvant chemoimmunotherapy (NADIM clinical trial, NCT03081689), considering their complete pathologic response (CPR) or non-CPR. Beyond TCR metrics, tissue clones were ranked by their frequency and spatiotemporal evolution of top 1% clones was determined. RESULTS: We have found a positive association between an uneven TCR repertoire in tissue samples at diagnosis and CPR at surgery. Moreover, TCR most frequently ranked clones (top 1%) present in diagnostic biopsies occupied greater frequency in the total clonal space of CPR patients, achieving an AUC ROC to identify CPR patients of 0.967 (95% confidence interval, 0.897-1.000; P = 0.001), and improving the results of PD-L1 tumor proportion score (TPS; AUC = 0.767; P = 0.026) or tumor mutational burden (TMB; AUC = 0.550; P = 0.687). Furthermore, tumors with high pretreatment top 1% clonal space showed similar immune cell populations but a higher immune reactive gene expression profile. Finally, the selective expansion of pretreatment tissue top 1% clones in peripheral blood of CPR patients suggests also a peripheral immunosurveillance, which could explain the high survival rate of these patients. CONCLUSIONS: We have identified two parameters derived from TCR repertoire analysis that could outperform PD-L1 TPS and TMB as predictive biomarkers of CPR after neoadjuvant chemoimmunotherapy, and unraveled possible mechanisms of CPR involving enhanced tumor immunogenicity and peripheral immunosurveillance.

AIM: To estimate management cost of NSCLC ALK+ patients with and without brain metastasis (BM), and to compare annual costs in patients treated with alectinib or crizotinib. METHODS: Management cost/year ( 2018) in patients with and without BM was estimated with disaggregated resource consumption provided by local oncologists, including medical visits, hospitalizations, diagnostic/laboratory tests, imaging techniques and surgical procedures. The comparison of costs/year with alectinib and crizotinib, considered the cumulative 12-month incidence of BM in ALEX trial (9.4 and 41.4%, respectively). RESULTS: Management cost was 6173.42/patient-year without BM and 21,637.50/patient-year with BM. With alectinib, average cost/patient was lower than crizotinib (4948.51/patient-year). CONCLUSION: Prevention of BM with alectinib may result in reductions of cost/year in the management of advanced ALK+ NSCLC.
RESUMO
Background: Automatization of insulin delivery by closed-loop systems represents a major step in type 1 diabetes management. The aim of this study was to analyze the effect of the commercialized hybrid closed-loop system, the MiniMed 670G system, on glycemic control, glycemic variability, and patient satisfaction. Methods: A prospective study, including type 1 diabetes patients consecutively starting on the 670G system in one adult and two pediatric hospitals, was performed. Baseline and 3-month visits were documented. Two weeks of data from the system were downloaded. Glycemic variability measures were calculated. Adults and adolescents completed a set of questionnaires (Gold and Clarke scores, Hypoglycemia Fear Survey, Diabetes Quality of Life [DQoL], Diabetes Treatment Satisfaction [DTS], Diabetes Distress Scale, Pittsburgh Sleep Quality Index). Results: Fifty-eight patients were included (age: 28 ± 15 years [7-63], <18 years old: 38% [n = 22], 59% [n = 34] females, previous use of SAP-PLGS [predictive low-glucose suspend]: 60% [n = 35]). HbA1c was reduced from 57 ± 10 to 53 ± 7 mmol/L (7.4% ± 0.9% to 7.0% ± 0.6%) (P < 0.001) and time in range 70-180 mg/dL was increased from 63.0% ± 11.4% to 72.7% ± 8.7% (P < 0.001). In patients with high baseline hypoglycemia risk, time <54 and <70 mg/dL were reduced from 0.9% ± 1.1% to 0.45% ± 0.7% (P = 0.021) and from 3.3% ± 2.8% to 2.1% ± 2.1% (P = 0.019), respectively. Glycemic variability measures improved. Time in auto mode was 85% ± 17%, the number of auto mode exits was 0.6 ± 0.3 per day, and the number of alarms was 8.5 ± 3.7 per day. Fear of hypoglycemia, DQoL, DTS, and diabetes distress improved, while the percentage of patients with poor sleep quality was reduced. The discontinuation rate was 3%. Conclusion: The commercialized hybrid closed-loop system improves glycemic control and glycemic variability in children and adults, reducing the burden of living with type 1 diabetes.
