RESUMEN

BACKGROUND: An acute vasodilator challenge is recommended in patients with heart failure and pulmonary hypertension during heart transplant evaluation. The aim of the study was to assess which hemodynamic parameters are associated with nonresponsiveness to the challenge. METHODS AND RESULTS: This study is a retrospective analysis of 402 patients with heart failure with pulmonary hypertension who underwent right heart catheterization and a pulmonary vasodilator challenge. Among the 140 who fulfilled the transplant guidelines eligibility criteria for the vasodilator challenge, 38 were responders and 102 nonresponders. At multivariable analysis, a diastolic blood pressure of <70 mm Hg, pulmonary vascular resistance of >5 Woods units, and pulmonary artery compliance of <1.2 mL/mm Hg were independently associated with poor response to vasodilator challenge (all P < .001). The presence of any 2 of these 3 conditions was associated with a 90% probability of being a nonresponder. The covariate-adjusted hemodynamic predictors of death in the entire population were a low baseline systolic blood pressure (P = .0017) and a low baseline right ventricular stroke work index (P = .0395). CONCLUSIONS: In patients with heart failure and pulmonary hypertension, low pulmonary arterial compliance, high pulmonary vascular resistance, and low diastolic blood pressure predict the nonresponsiveness to acute vasodilator challenge whilst a poor right ventricular function predicts a dismal prognosis.

RESUMEN

BACKGROUND: The first few months after admission are the most vulnerable period in patients with acute decompensated heart failure (ADHF). METHODS AND RESULTS: We assessed the association of the updated ADHF/N-terminal pro-B-type natriuretic peptide (NT-proBNP) risk score with 90-day and in-hospital mortality in 701 patients admitted with advanced ADHF, defined as severe symptoms of worsening HF, severely depressed left ventricular ejection fraction, and the need for i.v. diuretic and/or inotropic drugs. A total of 15.7% of the patients died within 90 days of admission and 5.2% underwent ventricular assist device (VAD) implantation or urgent heart transplantation (UHT). The C-statistic of the ADHF/NT-proBNP risk score for 90-day mortality was 0.810 (95% CI: 0.769-0.852). Predicted and observed mortality rates were in close agreement. When the composite outcome of death/VAD/UHT at 90 days was considered, the C-statistic decreased to 0.741. During hospitalization, 7.6% of the patients died. The C-statistic for in-hospital mortality was 0.815 (95% CI: 0.761-0.868) and Hosmer-Lemeshow χ(2)=3.71 (P=0.716). The updated ADHF/NT-proBNP risk score outperformed the Acute Decompensated Heart Failure National Registry, the Organized Program to Initiate Lifesaving Treatment in Patients Hospitalized for Heart Failure, and the American Heart Association Get with the Guidelines Program predictive models. CONCLUSIONS: Updated ADHF/NT-proBNP risk score is a valuable tool for predicting short-term mortality in severe ADHF, outperforming existing inpatient predictive models.

RESUMEN

Heart failure (HF) is a leading cause of morbidity worldwide, imposing a significant burden on deaths, hospitalizations, and health costs. Anticipating patients' deterioration is a cornerstone of HF treatment: preventing congestion and end organ damage while titrating HF therapies is the aim of the majority of clinical trials. Anyway, real-life medicine struggles with resource optimization, often reducing the chances of providing a patient-tailored follow-up. Telehealth holds the potential to drive substantial qualitative improvement in clinical practice through the development of patient-centered care, facilitating resource optimization, leading to decreased outpatient visits, hospitalizations, and lengths of hospital stays. Different technologies are rising to offer the best possible care to many subsets of patients, facing any stage of HF, and challenging extreme scenarios such as heart transplantation and ventricular assist devices. This article aims to thoroughly examine the potential advantages and obstacles presented by both existing and emerging telehealth technologies, including artificial intelligence.

RESUMEN

BACKGROUND: Clinical evaluation of central venous pressure is difficult, depends on experience, and is often inaccurate in patients with chronic advanced heart failure. We assessed the ultrasound-assessed internal jugular vein (JV) distensibility by ultrasound as a noninvasive tool to identify patients with normal right atrial pressure (RAP ≤7 mm Hg) in this population. METHODS: We measured JV distensibility as the Valsalva-to-rest ratio of the vein diameter in a calibration cohort (N=100) and a validation cohort (N=101) of consecutive patients with chronic heart failure with reduced ejection fraction who underwent pulmonary artery catheterization for advanced heart failure therapies workup. RESULTS: A JV distensibility threshold of 1.6 was identified as the most accurate to discriminate between patients with RAP ≤7 versus >7 mm Hg (area under the receiver operating characteristic curve, 0.74 [95% CI, 0.64-0.84]) and confirmed in the validation cohort (receiver operating characteristic, 0.82 [95% CI, 0.73-0.92]). A JV distensibility ratio >1.6 had predictive positive values of 0.86 and 0.94, respectively, to identify patients with RAP ≤7 mm Hg in the calibration and validation cohorts. Compared with patients from the calibration cohort with a high JV distensibility ratio (>1.6; n=42; median RAP, 4 mm Hg; pulmonary capillary wedge pressure, 11 mm Hg), those with a low JV distensibility ratio (≤1.6; n=58; median RAP, 8 mm Hg; pulmonary capillary wedge pressure, 22 mm Hg; P<0.0001 for both) were more likely to die or undergo a left ventricular assist device implant or heart transplantation (event rate at 2 years: 42.7% versus 18.2%; log-rank P=0.034). CONCLUSIONS: Ultrasound-assessed JV distensibility identifies patients with chronic advanced heart failure with normal RAP and better outcomes.

RESUMEN

AIM: To obtain real-world evidence about the features and risk stratification of pulmonary arterial hypertension (PAH) with a left heart disease (LHD) phenotype (PAH-LHD). METHODS AND RESULTS: By reviewing the records of consecutive incident PAH patients at 7 tertiary centers from 2001 to 2021, we selected 286 subjects with all parameters needed to determine risk of death at baseline and at first follow-up with COMPERA and COMPERA 2.0 scores. Fifty seven (20%) had PAH-LHD according to the AMBITION definition. Compared with no-LHD ones, they were older, had higher BMI, more cardiovascular comorbidities, higher E/e' ratio and left atrial area, but lower BNP concentrations and better right ventricular function and pulmonary hemodynamics. Survival was comparable between PAH-LHD and no-LHD patients, although the former were less commonly treated with dual PAH therapy. Both COMPERA and COMPERA 2.0 discriminated all-cause mortality risk of PAH-LHD at follow-up, but not at baseline. Risk profile significantly improved during follow-up only when assessed by COMPERA 2.0. At multivariable analysis with low-risk status as reference, intermediate-high and high-risk, but not LHD phenotype, were associated with higher hazard of all-cause mortality. Results were comparable in secondary analyses including patients in the last 10 years and atrial fibrillation and echocardiographic abnormalities as additional criteria for PAH-LHD. CONCLUSIONS: In real life, PAH-LHD patients are frequent, have less severe disease and are less likely treated with PAH drug combinations than no-LHD. The COMPERA 2.0 model may be more appropriate to evaluate their mortality risk during follow-up and how it is modulated by therapy.

RESUMEN

AIMS: The use of loop diuretics in pulmonary arterial hypertension (PAH) is less frequent compared with heart failure. The clinical and prognostic characteristics of PAH patients according to loop diuretic use remain unexplored. In this study, we retrospectively analysed the characteristics and survival of PAH patients requiring different doses of loop diuretics. METHODS AND RESULTS: Patients diagnosed with PAH between 2001 and 2022 at seven European centres for the management of PAH. According to the median equivalent dose of furosemide in the overall cohort, patients were divided into two subgroups: no/low-dose loop diuretic and high-dose loop diuretic. Primary outcome was 5 year all-cause mortality. Among the 397 patients included, 227 (57%) were treated with loop diuretics. Median daily furosemide equivalent dose was 25 mg, and accordingly patients were divided in no/low dose (i.e. ≤25 mg, n = 257, 65%) vs. high dose (i.e. >25 mg, n = 140, 35%). Patients in the high-dose group were older, more likely to have comorbidities, and had a more severe disease according to the ESC/ERS risk category. Crude 5 year survival was significantly shorter in patients in the high-dose group, but after adjustment for age, sex, and risk category, high loop diuretic dose was not significantly associated with the primary outcome. CONCLUSIONS: Use of high dose of loop diuretics in PAH is associated with a higher burden of comorbidities, more severe disease, and worse survival. However, in PAH, the need of high loop diuretic dose is a marker of disease severity and not an independent prognostic factor.

RESUMEN

Catheter-based revascularization procedures were developed as an alternative to systemic thrombolysis for patients with intermediate-high- and high-risk pulmonary embolisms. USAT IH-PE is a retrospective and prospective multicenter registry of such patients treated with ultrasound-facilitated, catheter-directed thrombolysis, whose preliminary results are presented in this study. The primary endpoint was the incidence of pulmonary hypertension (PH) at follow-up. Secondary endpoints were short- and mid-term changes in the echocardiographic parameters of right ventricle (RV) function, in-hospital and all-cause mortality, and procedure-related bleeding events. Between March 2018 and July 2023, 102 patients were included. The majority were at intermediate-high-risk PE (86%), were mostly female (57%), and had a mean age of 63.7 ± 14.5 years, and 28.4% had active cancer. Echocardiographic follow-up was available for 70 patients, and in only one, the diagnosis of PH was confirmed by right heart catheterization, resulting in an incidence of 1.43% (CI 95%, 0.036-7.7). RV echocardiographic parameters improved both at 24 h and at follow-up. In-hospital mortality was 3.9% (CI 95%, 1.08-9.74), while all-cause mortality was 11% (CI 95%, 5.4-19.2). Only 12% had bleeding complications, of whom 4.9% were BARC ≥ 3. Preliminary results from the USAT IH-PE registry showed a low incidence of PH, improvement in RV function, and a safe profile.

RESUMEN

Polycythemia vera (PV) is a chronic myeloproliferative disorder characterized by an abnormal increase in red blood cells. The involvement of the heart during the course of the illness represents a common cause of morbidity and it is linked to an increased thrombogenic risk subsequent to higher blood viscosity. In our study we evaluated by echocardiography a PV patient population. Our study enrolled 44 patients affected by PV. 17 of them were women and 27 were men. Mean patient age was 66.7. The average follow-up period was 5 years and the average duration of the illness was 5.7 years, since the time of diagnosis. All patients were evaluated quarterly by a cardiovascular objective examination and an ultrasound of the heart, with regard to platelet count and hematocrit (Ht) variations during the follow-up period, according to the therapy administered. Patients were treated with hydrossiurea and pipobroman and they underwent an eritrocitoapheresis in emergency conditions in which Ht levels rose too much, in spite of the myelosuppressive therapy. The echocardiographic assessment of the heart structure and function by the B mode technique revealed the presence of a sclerocalcific degeneration of the aortic valve in 58% of patients, involving the aortic root more then the valve. An average trans-aortic flow velocity of 1.92 m/s was detected by Doppler technique; a stenosis was demonstrated in 11 patients (25.5% of the entire population). After diagnosing the presence of a stenosis, we researched a possible cause of it. PV is a systemic disease well-known causing coronary thrombosis in a more or less high percentage of patients according to the record of cases taken into account. In our experience, more then thrombotic disease, found only in 13.4% of patients, we detected a high prevalence and incidence of mild to severe aortic stenosis, found in 25.5% of the sample studied. About all possible causes of stenosis, nowadays this results dependent of Ht values at moment of diagnosis, in the light of these results, it is reasonable to infer that aortic valve stenosis could depend by high haemodynamic stress on valve that is characteristic of polycythemic patients without chemotherapy.

RESUMEN

INTRODUCTION: Intravenous inotropic support represents an important therapeutic option in advanced heart failure (HF) as bridge to heart transplantation, bridge to mechanical circulatory support, bridge to candidacy or as palliative therapy. Nevertheless, evidence regarding risks and benefits of its use is lacking. METHODS: we conducted a retrospective single center study, analysing the effect of inotropic therapies in an outpatient cohort, evaluating the burden of hospitalizations, the improvement in quality of life, the incidence of adverse events and the evolution of organ damage. RESULTS: twenty-seven patients with advanced HF were treated in our Day Hospital service from 2014 to 2021. Nine patients were treated as bridge to heart transplant while eighteen as palliation. Comparing data regarding the year before and after the beginning of inotropic infusion, we observed a reduction of hospitalization (46 vs 25, p<0,001), an improvement of natriuretic peptides, renal and hepatic function since the first month (p<0,001) and a better quality of life in 53% of the population treated. Two hospitalizations for arrhythmias and seven hospitalizations for catheter-related complications were registered. CONCLUSIONS: in a selected population of advanced HF patients, continuous home inotropic infusion were able to reduce hospitalizations, improving end organ damage and quality of life. We provide a practical guidance on starting and maintaining home inotropic infusion while monitoring a challenging group of patients.

RESUMEN

BACKGROUND: Risk scores are important tools for the prognostic stratification of pulmonary arterial hypertension (PAH). Their performance and the additional impact of comorbidities across age groups is unknown. METHODS: Patients with PAH enrolled from 2001 to 2021 were divided in ≥65 years old vs <65 years old patients. Study outcome was 5-year all-cause mortality. French Pulmonary Hypertension Network (FPHN), FPHN noninvasive, Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) and Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL 2.0) risk scores were calculated and patients categorized at low, intermediate and high risk. Number of comorbidities was calculated. RESULTS: Among 383 patients, 152 (40%) were ≥65 years old. They had more comorbidities (number of comorbidities 2, IQR 1-3, vs 1, IQR 0-2 in <65 years patients). Five-year survival was 63% in ≥65 vs 90% in <65 years. Risk scores correctly discriminated the different classes of risk in the overall cohort and in the older and younger groups. REVEAL 2.0 showed the best accuracy in the total cohort (C-index 0.74, standard error-SE- 0.03) and older (C-index 0.69, SE 0.03) patients, whereas COMPERA 2.0 performed better in younger patients (C-index 0.75, SE 0.08). Number of comorbidities was associated with higher 5-year mortality, and consistently increased the accuracy of risk scores, in younger but not in older patients. CONCLUSIONS: Risk scores have similar accuracy in the prognostic stratification of older vs younger PAH patients. REVEAL 2.0 had the best performance in older patients and COMPERA 2.0 had it in younger patients. Comorbidities increased the accuracy of risk scores only in younger patients.

RESUMEN

AIMS: The angiotensin receptor-neprilysin inhibitor (ARNI), sacubitril/valsartan, has been shown to be effective in treatment of patients with heart failure (HF), but limited data are available in patients with advanced disease. This retrospective observational study assessed the effects of ARNI treatment in patients with advanced HF. METHODS AND RESULTS: We reviewed medical records of all advanced HF patients evaluated at our centre for unconventional therapies from September 2016 to January 2019. We studied 44 patients who started ARNI therapy and who had a haemodynamic assessment before beginning ARNI and after 6 ± 2 months. The primary endpoint was variation in pulmonary pressures and filling pressures at 6 months after starting ARNI therapy. Mean patient age was 51.6 ± 7.4 years; 84% were male. At 6 ± 2 months after starting ARNI, there was significant reduction of systolic pulmonary artery pressure [32 mmHg, interquartile range (IQR) 27-45 vs. 25 mmHg, IQR 22.3-36.5; P < 0.0001] and mean pulmonary artery pressure (20 mmHg, IQR 15.3-29.8 vs. 17 mmHg, IQR 13-24.8; P = 0.046). Five of 22 patients (23%) were deferred from the heart transplant list because of improvement, whereas four were listed de novo. After 23 ± 9 months, three patients were treated with a left ventricular assist device implantation, whereas six patients underwent heart transplantation (one in emergency conditions for refractory ventricular tachycardia). CONCLUSIONS: Sacubitril/valsartan is effective in reducing filling pressures and pulmonary pressures in patients with advanced HF. The absence of adverse events during follow-up suggests that sacubitril/valsartan is safe and well-tolerated in this cohort of patients.

RESUMEN

BACKGROUND: Patients in heart transplantation (HTx) waiting list for advanced heart failure (HF) are susceptible to acute deterioration refractory to standard HF medical therapies. Limited data are available on long-term in-hospital continuous intravenous (IV) inotropic therapy as bridge to definite therapies. METHODS AND RESULTS: We reviewed medical records of all heart transplant recipients treated in the pre-HTx phase with in-hospital continuous IV inotropes at our institution between 2012 and 2018. We analysed data before the beginning of continuous IV therapy and at the moment of HTx. We report data of 24 patients (mean age of 43.5 ± 15.7 years) treated with IV inotropes as bridge to HTx (median follow-up of 28 months after HTx). The main length of IV inotropic therapy was 84 ± 66 days (min 22; max 264 days). At the beginning, the most frequently used inotrope was dopamine (median dosage of 3 mcg/kg/min, interquartile range 2.5-3.75), alone (n = 11, 46%) or in combination with other inotropes (n = 13, 54%). In 18 patients, the class of inotropes was changed during the hospitalization. We registered a progressive improvement of perfusion markers and neuro-hormonal activation. CONCLUSION: In-hospital continuous parenteral inotropic therapy may serve as a temporary pharmacological bridge to HTx in patients with advanced HF that are actively listed to HTx with good reply in terms of prognosis and perfusion markers.

RESUMEN

AIM: To show that subclinical atherosclerosis (subclinical-ATS) of carotid arteries [intima-media thickness (IMT) or asymptomatic carotid plaque (ACP)], may provide additional information for risk stratification, in asymptomatic patients, aged greater than 45 years, with a cluster of risk factors (RFs). METHODS AND RESULTS: We studied 558 asymptomatic patients (235 males). RFs for atherosclerosis were assessed and the 10-year-risk was calculated according to the Italian risk score. Doppler ultrasound of carotid arteries identified the presence of IMT greater than 0.9 mm in 183 patients and ACP in 147 patients. One hundred and fifty-three patients developed cerebrovascular or cardiovascular (CV) events in the follow-up: 67 developed acute myocardial infarction, 39 developed angina, 25 had a stroke or transient ischemic attack, six died for CV events, and 16 underwent percutaneous or surgical revascularization. The incidence reflected the different risk profiles (4, 14, and 20%, respectively). However, in patients with baseline subclinical-ATS the incidence of events increased to 35, 46, and 63%, respectively. In the multivariate analysis the incidence of events was significantly influenced by the presence of asymptomatic carotid lesions in each risk category. CONCLUSION: In our experience, the incidence of CV events is enhanced in patients with subclinical-ATS. Increased IMT and ACP predict CV events and improve the risk stratification of asymptomatic patients aged greater than 45 years and with a cluster of RFs, in a long-term follow-up.

RESUMEN

BACKGROUND: It is well-known that a reduction of the cardiac frequency variability, measurable with the Heart Rate Variability (HRV) system, is an indirect expression of the sympathetic-autonomic tone. Another index, Heart Rate Turbulence (HRT), has been recently suggested as a possible unit of measurement for the sympathetic-autonomic tone: this system allows to estimate the baro-reflex response of the carotid arteries to an early ventricular extra-systole by analysing heart rate variations induced by a premature beat. METHODS AND RESULTS: In our research we have analyzed this phenomenon in patients affected by moderate or severe cardiac failure. In particular, we divided 110 patients into two arms: subjects with or without a history of resuscitated arrhythmic death, that is, patients with high or low arrhythmic potential. In a detailed analysis of the sympathetic-autonomic tone, using both the above-mentioned parameters, HRV showed an irrelevant statistical difference between the two arms; on the contrary, HRT showed a significant statistical difference. CONCLUSIONS: If our conclusions will be confirmed by next larger reports, HRT could become a reliable index for screening the arrhythmic potential of patients affected by cardiac failure, to select the ones who need a defibrillator implantation.

RESUMEN

Introducción: El schwannoma (neurinoma o neurilemoma) es un tumor benigno originado en la vaina de mielina de los nervios periféricos a partir de la células de Schwann. En su variedad benigna es el tumor más frecuente dependiente de esta estructuras. Se manifiesta entre la tercera y quinta década de vida, sin distinción de género. La localización axilar es extremadamente infrecuente, constituyendo el 5% de todos los casos reportados. Los schwannomas son tumores bien delimitados y de lento crecimiento. La presentación más frecuente es como masa palpable o por la sintomatología clínica correspondiente al territorio de inervación del nervio afectado. Es importante tener en cuenta que estas lesiones puedes formar parte de cuadros clínicos de base genética más complejos como la neurofibromatosis, entre otros. El método diagnóstico de elección es la resonancia magnética nuclear. El tratamiento consiste en la extirpación de la lesión tratando de preservar la función de la estructura nerviosa afectada. Objetivo: El objetivo del presente trabajo es realizar el reporte de un caso de lesión compatible con schwannoma axilar y realizar un revisión de la literatura.


Introduction: Schwannoma (neurinoma or neurilemoma) is a benign tumor originated in myelin sheath of peripheral nerves from schwann cells. In its benign variety, it is the most frequent tumor dependent of these structures. It appears between the third and fifth decade of life without distinction of geder. Axillary location is extremely rare, accounting for 5% of all reported cases. Schwqnnomas are well-defide, slow-growing tumors. The most frequent presentation is as palpabel mass or due to the clinical symptoms corresponding to the innervation territory of the affected nerve. It's important to know that these lesions can be part of more complex genetic-based clinical cases such as neurofibromatosis. The diagnostic method of choice is magnetic resonance imaging. Treatment cosists of excising the lesion, trying to preserve the function of the affected nerve structure. Objetive: The aim of this report is to describe our experience with one case of axillary schwannoma diagnosed in our institution and to perform a review of the literature.

RESUMEN

The role of the right ventricle has often been underestimated in heart failure. It has been thought that the right cavity has a less prominent impact on symptoms, therapeutic approach, and prognosis. Right ventricular dysfunction is a complex issue and its diagnosis has acquired a relevant role, in particular with the improvement of new therapeutic options such as ventricular assist devices. The complex geometry of the right ventricle and its interaction with the left ventricle are still a matter of debate, leaving several open questions about the best therapeutic approach to manage right ventricular dysfunction. Echocardiography remains the first-line imaging technique, but an integrated multimodality evaluation with clinical, biochemical and hemodynamic parameters, and cardiovascular magnetic resonance imaging can provide a more comprehensive way to choose the most appropriate treatment for patients with heart failure associated with right ventricular dysfunction.

RESUMEN

Introducción Las pacientes con Carcinoma Ductal in Situ de mama (cdis) tienen mayor riesgo de desarrollar carcinoma invasor. Aquellas con receptores hormonales positivos se beneficiarían con hormonoterapia. El largo período de tratamiento y los efectos adversos asociados al mismo hacen dificultosa la adherencia. Objetivos El objetivo del presente trabajo es analizar la adherencia a la hormonoterapia en pacientes operadas por Carcinoma Ductal in Situ en el Hospital Universitario Austral. Material y método Es un estudio observacional, analítico, de corte transversal. Se incluyeron pacientes con diagnóstico de Carcinoma Ductal in Situ que fueron intervenidas quirúrgicamente en el Hospital Universitario Austral en el período comprendido entre el 24 de julio de 2000 y el 5 de julio de 2017. Los datos fueron recopilados a través de una encuesta. Resultados Se obtuvieron 100 encuestas. La adherencia fue del 82%. La misma no se modificó según edad, conocimiento de riesgos y beneficios del tratamiento, tipo y número de cirugías, radioterapia y número de consultas. Las reacciones adversas a la medicación fueron la causa más frecuente de abandono al tratamiento. Conclusiones El tratamiento multidisciplinario podría asegurar un óptimo nivel de adherencia


Introduction Patients with Ductal Carcinoma in Situ of the breast (dcis) have a higher risk of developing invasive carcinoma. Those with hormone receptor-positive would benefit from hormonal therapy. The long period of treatment and the associated adverse events make adherence difficult. Objectives The aim of this study is to analyze the adherence of hormonal therapy in operated patients with Ductal Carcinoma in Situ at Hospital Universitario Austral. Materials and method It is an observational, analytical and cross-sectional study. Patients diagnosed with Ductal Carcinoma in Situ who underwent surgery at Hospital Universitario Austral in the period between 07/24/2000 and 07/05/2017 were included. The data was collected through a survey. Results 100 surveys were obtained. The adherence was 82%. It was not modified according to age, knowledge of risks and benefits of the treatment, type and number of surgeries, radiotherapy and number of consultations. Adverse events were the most frequent cause of discontinue of treatment. Conclusions Multidisciplinary treatment could ensure an optimal level of adherence

RESUMEN

Introducción El cáncer de mama hereditario es el 10% de los cánceres mamarios a expensas principalmente de los genes brca 1 y 2. La identificación de pacientes de Alto Riesgo inicia el proceso de Asesoramiento Genético en Oncología (ago). Objetivo Presentar nuestra experiencia inicial de Asesoramiento Genético, evaluando las Estrategias de Reducción de Riesgo y las variables que influyeron en la toma de decisiones. Material y método Se analizaron en forma retrospectiva los registros clínicos de las pacientes consideradas de Alto Riesgo Heredo Familiar (arhf) que concurrieron a la consulta desde junio del año 2000 a enero de 2019. Las variables analizadas fueron: edad, antecedente personal de cáncer de mama, antecedentes familiares de cáncer de mama y ovario, derivación a ago, concurrencia a la consulta, solicitud de test genético, realización del mismo y Estrategia de Reducción de Riesgo adoptada. Resultados Analizamos 420 pacientes, 228 (54%) con cáncer de mama y 192 (46%) sanas. Fueron derivadas a ago 335 (80%) de las cuales concurrieron 224 (67%). Se les solicitó estudio genético a 195 (87%); de ellas 164 (84%) pudieron realizarlo, con el siguiente resultado: 46 fueron brca positivas, 90 negativas y 22 con Variantes de Significado Incierto. Se realizaron 68 (16%) Mastectomías de Reducción de Riesgo, 293 pacientes (70%) ingresaron en Vigilancia, 1 paciente en Quimioprevención y 58 pacientes (14%) quedaron pendientes. El 67% de las pacientes brca positivas eligieron cirugía. El estado brca positivo y la edad menor de 50 años fueron variables independientes significativas para la conducta quirúrgica. Conclusiones Las pacientes de Alto Riesgo deben ser tratadas en equipos multidisciplinarios a fin de optimizar el proceso de Asesoramiento Genético. La decisión de la Estrategia de Reducción de Riesgo puede estar influenciada por la edad, el antecedente personal de cáncer y un resultado brca mutado


Introduction Hereditary breast cancer is 10% of breast cancers at the expense mainly of the brca 1 and 2 genes. The identification of High Risk patients begins the process of Genetic Counseling in Oncology Objective We present our initial experience in the Genetic Counseling process, evaluating the Risk Reduction Strategies and the variables that influenced decision making. Materials and method We retrospectively analyzed the clinical records of patients considered to be High Risk Family Inheritance (arhf) who attended the consultation from June 2000 to January 2019. The variables analyzed were: age, personal history of breast cancer, family history of breast and ovarian cancer, referral to ago, attendance at the consultation, request for genetic testing, performance of the same and Risk Reduction Strategy adopted. Results We analyzed 420 patients, 228 (54%) with breast cancer and 192 (46%) healthy. 335 (80%) were referred to ago, 224 (67%) attended. 195 (87%) were asked for a genetic study and 164 (84%) were able to do it. Of these, 46 were brca Positive, 90 Negative and 22 with Variants of Uncertain Meaning. 68 (16%) Risk Reduction Mastectomies were performed, 293 (70%) chose Surveillance, 1 patient in Chemoprevention and 58 patients (14%) pending. 67% of brca + patients chose surgery. Positive brca status and age under 50 years were significant independent variables for surgical behavior. Conclusions High-risk patients should be treated in multidisciplinary teams in order to optimize the genetic counseling process. The decision of the Risk Reduction Strategy may be influenced by age, personal history of cancer and a mutated brca result
