El estudio de las bronquiectasias ha generado un interés creciente. Se continúa investigando sobre la verdadera prevalencia (los escasos trabajos publicados muestran resultados muy dispares), los mecanismos implicados o su relación con otras patologías. Además, se desconocen los datos en la población asintomática. Los individuos sin síntomas que participan en un programa de cribado de cáncer de pulmón mediante Tomografía Computarizada de baja dosis de radiación (TCBD), son una población idónea para estudiar enfermedades en estadios precoces. En un programa de cribado la aparición de falsos positivos suponen un problema. Las bronquiectasias podrían dar lugar a falsos positivos que supongan un daño para el paciente. Por último, cabe plantearse si las bronquiectasias comparten algún mecanismo que pueda influir en el desarrollo del cáncer. Se estudiaron los pacientes incluidos en el programa I-ELCAP (International Early Lung Cancer Program) en la Clínica Universidad de Navarra, entre los años 2000 y 2012, seguidos hasta el 2014. En la evaluación inicial se realizó una TCBD basal, un cuestionario epidemiológico y una espirometría. En función de los hallazgos de las TCBD se aplicó el protocolo de I-ELCAP del que se extrajo un listado de los sujetos con bronquiectasias. La elección de los individuos sin bronquiectasias se realizó mediante emparejamiento 1:1 por sexo, tabaquismo y edad. Para la medición de la gravedad y extensión de las bronquiectasias se utilizó la escala de Bhalla. Se incluyeron en el programa P-IELCAP 3028 sujetos y se identificaron 354 individuos con bronquiectasias, predominantemente varones (73%), con una edad media de 60,9 años y un consumo medio de tabaco de 40 paquetes-año. Por tanto, la prevalencia de bronquiectasias fue del 11,7%. Tras aplicar la escala de Bhalla, se observó que la mediana de puntuación de las bronquiectasias fue de 7 puntos. Se identificaron 307 pacientes con grado de enfermedad leve, 46 moderada y solo 1 paciente con afectación grave. Un 45% de los pacientes las presentaba de forma bilateral. La afectación por generaciones resultó ser homogénea. El daño de ambos lóbulos superiores se presentó en 42 casos y de ambos lóbulos inferiores en 67. Los pacientes con bronquiectasias mostraban más frecuentemente obstrucción al flujo aéreo, mayor gravedad de la misma y mayor presencia de enfisema. No se observaron diferencias en la prevalencia de antecedentes de infección u otras enfermedades. De los 354 individuos con bronquiectasias en la TCBD inicial se observaron nódulos pulmonares en un 53% y un 17% en los que no las presentaban. Los falsos positivos fueron mayores entre los pacientes con bronquiectasias (26% vs. 17%), lo que condujo a una mayor proporción de TCBD en los sujetos con bronquiectasias y más indicaciones de toma de antibióticos. No hubo diferencias en el número de cánceres. En los TCBD de seguimiento se encontraron más nódulos nuevos en pacientes con bronquiectasias que en los sujetos control (17% y 12%). El número de falsos positivos durante el seguimiento fue de 129 para los pacientes con bronquiectasias frente a 88 para el otro grupo. La necesidad de pruebas adicionales o antibióticos en los pacientes con bronquiectasias versus sujetos sin bronquiectasias fue mayor para TCBD y toma de antibiótico. Trece pacientes fueron diagnosticados de cáncer, 6 en el grupo de bronquiectasias y 7 en sus respectivos controles (p= 0,77). En las espirometrías basales se observa un 55% de obstrucción al flujo aéreo en el grupo de bronquiectasias y un 45% en los individuos sin ellas. Del total de 708 sujetos, se estudian 203 pacientes con datos de función pulmonar tanto al inicio como al final del programa. En ambos grupos se observa una caída del FEV1 significativa, sin diferencias entre ambos grupos. La caída del FEV1 tanto total como anual se asocia a la cantidad de paquetes-año fumados, pero no a la presencia de bronquiectasias, la edad ni el sexo.

1. INTRODUCIÓN En España se detectan anualmente más de 23.000 casos de cáncer de pulmón (CP) con una tasa de supervivencia del 18 % luego de cinco años. Determinada básicamente por la naturaleza asintomática del CP durante los estadios iniciales, solo un 16% de los casos se diagnostican en esta etapa. El cribado de CP con TCBD ha mostrado eficacia en la detección y diagnóstico del CP en fase inicial. Un tema muy debatido en el cribado son los falsos positivos, pacientes sanos con nódulos pulmonares indeterminados que se someten a procedimientos quirúrgicos o no, con consecuencias físicas y emocionales. Luego de dos décadas del inicio del programa PELCAP, el de mayor duración en Europa, el número de pacientes quirúrgicos diagnosticados con CP nos permitió analizar y describir sus resultados y las posibles causas de los falsos positivos (FP). 2. OBJETIVOS 1. Describir las características y resultados obtenidos en pacientes tratados quirúrgicamente. 2. Analizar el subgrupo sometido a cirugía y cuyo diagnóstico final no fue de CP. 3. Comparar a partir de tres encuestas validadas, el nivel de satisfacción y la CDV entre los intervenidos quirúrgicamente y cuyo diagnóstico final fue cáncer o enfermedad benigna. 3. MATERIAL Y METODOS El universo considerado fueron los pacientes reclutados entre septiembre de 2000 y diciembre de 2019 y que fueron sometidos a cirugía. 1. Antes de la resección pulmonar, el mediastino se evaluó en función de los hallazgos del TCBD o PET, a través de EBUS, EUS o mediastinoscopia. En todos los casos, un equipo multidisciplinario decidió las intervenciones quirúrgicas u oncológicas. 2. Revisión detallada de las historias clínicas e imágenes de los FP, permitiendo así una auditoría basada en la valoración de cada prueba realizada y contrastarla con la información incluida en los algoritmos. 3. Se evaluaron mediante tres encuestas validadas a 24 pacientes, 8 FP junto a 16 diagnosticados de CP como grupo control emparejado (1:2). El comité de ética de la Universidad de Navarra aprobó el protocolo de estudio y todos los sujetos firmaron un consentimiento. 4. RESULTADOS 1. Participaron 3825 sujetos en el programa de cribado, 97 (2.5%) CP fueron diagnosticados en 95 pacientes. Solo 14 pacientes (16,1%) tuvieron un diagnóstico preoperatorio no quirúrgico de CP. Se realizaron 87 cirugías en 75 pacientes por sospecha de CP. 59 (88,1%) fueron diagnosticados en estadio I. Las tasas de supervivencia para los pacientes en estadio I a los 5 y 10 años fueron de 93% y 83% respectivamente. 2. 7 de los 8 pacientes FP del proceso de cribado no siguieron correctamente el algoritmo I-ELCAP. 3. El grupo de FP mostró un alto grado de satisfacción respecto a la calidad asistencial en el EORTC IN-PATSAT32, una excelente CDV en sus dimensiones física y emocional en el SF12, y un alto grado de satisfacción respeto a la percepción de su salud en el SATISCORE. En este último, el 100% de los encuestados afirmaron que se someterían de nuevo a cirugía bajo las mismas circunstancias. 5. CONCLUSIONES 1. El cribado de CP mediante TCBD anual permite su diagnóstico precoz. 2. Las tasas de supervivencia a largo plazo en pacientes diagnosticados supera el 80%. 3. El porcentaje de FP fue de 9,2%. 4. El seguimiento riguroso del protocolo, asociado a una gestión multidisciplinar integrada y coordinada, podría resultar en una baja tasa de FP. 5. La provisión de información adecuada y oportuna sobre beneficios y riesgos del cribado, junto con una asistencia integral de alta calidad, favorecen un alto grado de satisfacción y la disminución del impacto psicosocial en pacientes intervenidos por lesiones benignas o no. 6. Los sujetos falsos positivos en ausencia de complicaciones, mostraron alto grado de satisfacción y CDV en sus dimensiones física y mental.

- Abstract
Introduction: The Spanish COPD guidelines (GesEPOC) have been recently modified. The aim of this study is to assess this revision and evaluate the prognosis of patients according to the new classification of severity. Methods: A total of 700 COPD patients (83.9% men) were prospectively followed up for a mean period of 5 years in tertiary hospitals in Spain and the USA. Anthropometric data, lung function tests, dyspnea (according to the mMRC scale), BODE and Charlson index were collected. We calculated mortality at 5 years following the risk criteria proposed by the new GesEPOC. Results: Mean age was 66 ± 9.6 years and mean FEV1% was 59.7 ± 20.2. The proportion of patients in the low-risk group was 40.43%. Patients in the high-risk group had a significantly higher BODE index than those in the low-risk group (2.92 ± 0, 66 vs. 0.52 ± 1.91, p < 0.001), while the Charlson index score was similar in both groups. Mortality at 60 months was significantly higher in the high-risk group (31.7% vs. 15.5%, p < 0.001). Dyspnea and FEV1% were also independent predictors of mortality (p < 0.001), and neither was inferior to the risk classification proposed by GesEPOC. Conclusions: The new severity index proposed by GesEPOC accurately predicts 5-year mortality. However, dyspnea and FEV1% have the same strength in predicting mortality.

A lung transplant is usually the final therapeutic option for patients with respiratory insufficiency. In spite of the many advances in immunology and the management of complications, mortality and morbidity associated with this transplant are far higher than with others. Acute rejection is an almost universal problem in the first year, while obliterative bronchitis reduces long term survival. Respiratory infections also play a significant role in the complications associated with lung transplants due to the constant exposure of the graft to the outside. However, the success of this therapeutic option, which basically depends on a suitable selection of donor and recipient, are evident, above all with respect to quality of life.

Cáncer de pulmón ,FICTION ,Lavado broncoalveolar ,Citogenética ,Esputo ,Detección precoz - Abstract
El cáncer de pulmón es una de las causas de muerte más frecuentes en el mundo occidental. La supervivencia global de los pacientes no supera el 15% a los 5 años, debido principalmente a que la mayor parte de los casos se diagnostican en estadios avanzados. Además de la prevención primaria, mediante la reducción del consumo de tabaco, son necesarias nuevas tecnologías para el diagnóstico precoz de la enfermedad. Estudios recientes han demostrado que el TAC helicoidal del tórax es efectivo en la detección de nódulos pulmonares malignos en estadios precoces. En la actualidad se está valorando su eficacia en series amplias de pacientes de alto riesgo. Recientemente se ha desarrollado una nueva técnica de citogenética molecular, el FICTION (Fluorescence Immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation of Neoplasms). Esta técnica permite el análisis simultáneo de marcadores inmunofenotípicos y alteraciones genéticas presentes en las células tumorales. El objetivo de nuestro proyecto es su puesta a punto para el estudio de muestras de esputo y lavado broncoalveolar de pacientes con cáncer de pulmón. El fin último es estudiar la posibilidad de que esta técnica pueda ser utilizada, junto con el TAC helicoidal, en programas de detección precoz de cáncer de pulmón, para pacientes de alto riesgo. En este trabajo presentamos una revisión de la contribución de las distintas técnicas de citogenética al estudio del cáncer de pulmón y la metodología de trabajo que vamos a llevar a cabo en nuestro proyecto.

- Abstract
Objective: To determine the accuracy of visual analysis and the retention index (RI) with dual-time point
18 F-FDG PET/CT for the characterization of indeterminate pulmonary nodules (IPN) with low FDG uptake., Materials and Methods: A retrospective analysis was performed on 43 patients (28 men, 64 ± 11 years old, range 36-83 years) referred for IPN characterization with18 F-FDG-PET/CT and maximum standard uptake value ≤ 2.5 at 60 minutes post-injection (SUVmax1 ). Nodules were analyzed by size, visual score for FDG uptake on standard (OSEM 2,8) and high definition (HD) reconstructions, SUVmax1 , SUVmax at 180 minutes post-injection (SUVmax2 ), and RI was calculated. The definitive diagnosis was based on histopathological confirmation (n = 28) or ≥ 2 years of follow-up., Results: Twenty-four (56%) nodules were malignant. RI ≥ 10% on standard reconstruction detected 18 nodules that would have been considered negative using the standard SUVmax ≥ 2.5 criterion for malignancy. RI ≥ 10% had a sensitivity, specificity, PPV, NPV and accuracy of 75, 73.7, 78.3, 70, and 74.4%, respectively, while for FDG uptake > liver on HD these were 79.1, 63.2, 73.1, 70.6, and 72.1%, respectively. SUVmax1 ≥ 2, SUVmax2 > 2.5 and FDG uptake > liver on standard reconstruction had a PPV of 100%. FDG uptake > mediastinum on HD had a NPV of 100%., Conclusions: RI ≥ 10% was the most accurate criterion for malignancy, followed by FDG uptake > liver on HD reconstruction. On standard reconstruction, SUVmax1 ≥2 was highly predictive of malignancy, as well as SUVmax2 > 2.5 and FDG uptake > liver. FDG uptake < mediastinum on HD was highly predictive of benign nodules., (Copyright © 2020 Sociedad Española de Medicina Nuclear e Imagen Molecular. Publicado por Elsevier España, S.L.U.

- Abstract
Objective: Lung cancer (LC) is the leading cause of death from cancer worldwide. More than 27,000 LCs are diagnosed annually in Spain, and most are unresectable. Early detection and treatment reduce LC mortality. This study describes surgical outcomes in a longstanding LC screening cohort in Spain., Methods: We conducted a retrospective study of surgical outcomes in a LC screening (LCS) program using low dose computed tomography (LDCT) since the year 2000. A descriptive analysis of clinical and radiological parameters, presence or absence of a preoperative diagnosis, pathological staging, morbidity, mortality, and survival was performed., Results: Ninety-seven (2.5%) LC were diagnosed in 3825 screened. Twenty individuals with LC had no surgery due to advanced stage or small cell histology. Eighty-seven surgical procedures were carried out for suspected or biopsy proven LC, detected by LDCT. Most operated patients were male (57[85%]) aged 64±9.1 years. Nine patients underwent a second operation for a metachronous primary lung cancer. Mean tumor size was 15.2±7.6mm. Eight nodules were benign (9.2%). Lobectomy was performed in 56 cases (83.6%). Adenocarcinoma (n=39; 58.2%) was the most frequent histological type followed by squamous cell carcinoma (n=17; 25.4%). Fifty-nine (88%) tumors were in Stage I. Thirteen patients (15.4%) had 16 complications. The estimated survival rates at 5 and 10 years for stage I were 93% (95% CI: 79%-98%) and 83% (95% CI: 65%-92%), respectively., Conclusion: Lung cancer screening was associated with excellent surgical outcomes with 5 and 10-year survival rates exceeding 90 and 80%, respectively., (Copyright © 2020 SEPAR.

- Abstract
Introduction and Objective: Polysomnography (PSG) is the gold standard technic for the diagnosis of obstructive sleep apnea syndrome (OSAS). It is an expensive, complex and not always available technic, meaning that respiratory polygraphy (RP) has become usual. Although RP is not validated in low probability patients, Spanish guidelines recommend conservative treatment in patients with negative RP. We intended to study the prevalence and severity of OSAS through PSG in a sample of patients with low probability and negative RP., Material and Methods: Retrospective, observational, descriptive and analytic study of low probability OSAS patients with negative RP in whom a PSG was performed. Anthropometric, clinical and sleep data were collected., Results: Eighty-two patients were included. After PSG, a greater number of hypopneas (137.8±70.1 vs. 51.2±38.4 [P<.05]) and apnea hypopnea index (27.8±15.6 vs. 11.7±7.1 [P<.05]) was observed, as well as an increment in OSAS prevalence of 17%, which was 35% in severe OSAS. In mild OSAS, there was a decrement of 41%., Conclusion: According with the results of this study, RP significantly underestimates the prevalence and severity of OSAS in low probability patients. While it is necessary to adequately stratify the OSAS probability in order to correctly indicate diagnosis tests, we recommend performing a PSG in low probability patients with negative RP., (Copyright © 2015 Elsevier España, S.L.U.

- Abstract
In screening programs, overdiagnosis is defined as the detection of a disease that would have gone undetected without screening when that disease would not have resulted in morbimortality and was treated unnecessarily. Overdiagnosis is a bias inherent in screening and an undesired effect of secondary prevention and improved sensitivity of diagnostic techniques. It is difficult to discriminate a priori between clinically relevant diagnoses and those in which treatment is unnecessary. To minimize the effects of overdiagnosis, screening should be done in patients at risk., (Copyright © 2014 SERAM. Published by Elsevier España, S.L.U. All rights reserved.)

- Abstract
Objective: To describe the clinical characteristics and survival of patients diagnosed with bronchogenic carcinoma during the years 2000 and 2001 in a tertiary level hospital., Patients and Methods: Data were collected from our hospital's tumor registry and validated with independent sources. Of all the patients diagnosed with or treated for bronchogenic carcinoma in our hospital, only those from our health care area were selected., Results: During the 2-year study period, 482 patients were diagnosed. Of those, 91% were men. The mean (SD) age was 66.6 (9.65) years. Large cell carcinomas accounted for 29.4% of cases. Of all the cases of bronchogenic carcinoma, 41.3% were diagnosed in stage IV. Thirty percent of non-small cell carcinomas were classified as stage I, compared to 6% of small cell carcinomas (P< .001). The most frequent treatment was chemotherapy (42.1%) and 20% of patients underwent surgery. The overall 5-year survival rate was 13% (95% confidence interval [CI], 10%-16%), while survival was significantly lower in patients aged 68 years or older (95% CI, 3%-15%; P< .001) and in patients with small cell carcinoma (0%, P< .01)., Conclusions: Our recent experience (2000-2001) confirmed the advanced age of patients with bronchogenic carcinoma, the frequency of diagnosis in advanced stages of the disease (41% in stage IV), and the low overall 5-year survival rate (13%).

- Abstract
Lung cancer is one of the most frequent causes of cancer death in Western countries. Overall 5-year survival rate is lower than 15% mainly due to the late diagnosis of the disease. Primary prevention (reduction of tobacco consumption) and more effective methods for early detection are needed. Some studies have recently shown that low-dose spiral computed tomography (CT) is a useful technique to the detection of pulmonary malignant nodules in early stages. Studies are developing to evaluate its efficacy in series of high-risk patients. A new cytogenetic technique has been developed: the FICTION technique (Fluorescence Immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation of Neoplasms). This technique allows the simultaneous study of immunophenotypic markers and genetic abnormalities present in tumour cells. The goal of our project is optimise this technique in sputum and bronchoalveolar lavage specimens from lung cancer patients. The overall goal of this project is evaluate the usefulness of this technique, together with the new radiological techniques, in early detection programs of lung cancer in high-risk patients. In the present study we review the cytogenetic studies on lung cancer carried out in the recent years. We also introduce the basic methodological aspects that will be developed in our project.

- Abstract
Lung reduction has been show to be a promising treatment for the final phases of non-bullous pulmonary emphysema. The role of video-assisted thoracoscopy (VAT) in this disease has not yet been established. We report a case of bilateral non-bullous pulmonary emphysema in which transplantation was ruled out because of laryngeal neoplasm treated three months earlier. Using VAT, we performed bilateral lung reduction in the apical zones with good therapeutic results. We find that in patients reduction by VAT, although not a curative treatment, leads to immediate postoperative improvement in lung function and dyspnea, and does not exclude the possibility of later performing lung transplantation.
