Surgical Risk Following Anatomic Lung Resection in Thoracic Surgery: A Prediction Model Derived from a Spanish Multicenter Database. / Riesgo quirúrgico tras resección pulmonar anatómica en cirugía torácica. Modelo predictivo a partir de una base de datos nacional multicéntrica.

INTRODUCTION: The aim of this study was to develop a surgical risk prediction model in patients undergoing anatomic lung resections from the registry of the Spanish Video-Assisted Thoracic Surgery Group (GEVATS). METHODS: Data were collected from 3,533 patients undergoing anatomic lung resection for any diagnosis between December 20, 2016 and March 20, 2018. We defined a combined outcome variable: death or Clavien Dindo grade IV complication at 90 days after surgery. Univariate and multivariate analyses were performed by logistic regression. Internal validation of the model was performed using resampling techniques. RESULTS: The incidence of the outcome variable was 4.29% (95% CI 3.6-4.9). The variables remaining in the final logistic model were: age, sex, previous lung cancer resection, dyspnea (mMRC), right pneumonectomy, and ppo DLCO. The performance parameters of the model adjusted by resampling were: C-statistic 0.712 (95% CI 0.648-0.750), Brier score 0.042 and bootstrap shrinkage 0.854. CONCLUSIONS: The risk prediction model obtained from the GEVATS database is a simple, valid, and reliable model that is a useful tool for establishing the risk of a patient undergoing anatomic lung resection.

Spanish Video-Assisted Thoracic Surgery Group: Method, Auditing, and Initial Results From a National Prospective Cohort of Patients Receiving Anatomical Lung Resections / Grupo Español de Cirugía Torácica Videoasistida: Método, Auditoría y Resultados Iniciales de una Cohorte Nacional Prospectiva de Pacientes Tratados con Resección Pulmonar Anatómica

INTRODUCTION: Our study sought to know the current implementation of video-assisted thoracoscopic surgery (VATS) for anatomical lung resections in Spain. We present our initial results and describe the auditing systems developed by the Spanish VATS Group (GEVATS). METHODS: We conducted a prospective multicentre cohort study that included patients receiving anatomical lung resections between 12/20/2016 and 03/20/2018. The main quality controls consisted of determining the recruitment rate of each centre and the accuracy of the perioperative data collected based on six key variables. The implications of a low recruitment rate were analysed for "90-day mortality" and "Grade IIIb-V complications". RESULTS: The series was composed of 3533 cases (1917 VATS; 54.3%) across 33 departments. The centres' median recruitment rate was 99% (25-75th:76-100%), with an overall recruitment rate of 83% and a data accuracy of 98%. We were unable to demonstrate a significant association between the recruitment rate and the risk of morbidity/mortality, but a trend was found in the unadjusted analysis for those centres with recruitment rates lower than 80% (centres with 95-100% rates as reference): grade IIIb-V OR = 0.61 (p = 0.081), 90-day mortality OR = 0.46 (p = 0.051). CONCLUSIONS: More than half of the anatomical lung resections in Spain are performed via VATS. According to our results, the centre's recruitment rate and its potential implications due to selection bias, should deserve further attention by the main voluntary multicentre studies of our speciality. The high representativeness as well as the reliability of the GEVATS data constitute a fundamental point of departure for this nationwide cohort

INTRODUCCIÓN: Nuestro estudio buscó conocer el grado de implementación actual de la cirugía toracoscópica asistida por video (VATS, por sus siglas en inglés) para las resecciones pulmonares anatómicas en España. Presentamos nuestros resultados iniciales y describimos los sistemas de auditoría desarrollados por el grupo español de VATS (GEVATS). MÉTODOS: Realizamos un estudio de cohortes prospectivo multicéntrico que incluyó pacientes que fueron tratados con resecciones pulmonares anatómicas entre el 20/12/2016 y el 20/03/2018. Los controles de calidad principales consistieron en determinar la tasa de reclutamiento de cada centro y la precisión de los datos perioperatorios recolectados en base a seis variables clave. Se analizaron las implicaciones de una baja tasa de reclutamiento para "mortalidad a los 90 días" y "complicaciones de grado IIIb-V". RESULTADOS: La serie estaba compuesta por 3533 casos (1917 VATS; 54,3%) en 33 servicios. La mediana de la tasa de reclutamiento de los centros fue del 99% (p25-p75: 76-100%), con una tasa de reclutamiento global del 83% y una precisión de los datos del 98%. No pudimos demostrar una asociación significativa entre la tasa de reclutamiento y el riesgo de morbi-mortalidad, pero se encontró una tendencia en el análisis no ajustado para aquellos centros con tasas de reclutamiento inferiores al 80% (usando los centros con tasas de 95-100% como referencia): OR = 0,61 para el grado IIIb-V (p = 0,081), OR = 0,46 para la mortalidad a los 90 días (p = 0,051). CONCLUSIONES: Más de la mitad de las resecciones pulmonares anatómicas en España se realizan a través de VATS. Según nuestros resultados, la tasa de reclutamiento del centro y sus posibles implicaciones debido al sesgo de selección, deberían recibir más atención por parte de los principales estudios multicéntricos voluntarios de nuestra especialidad. La alta representatividad y la confiabilidad de los datos de GEVATS constituyen un punto de partida fundamental para esta cohorte nacional

The Spanish Society of Pulmonology and Thoracic Surgery Lung Cancer Cooperative Group-II registry. A descriptive study.

INTRODUCTION AND OBJECTIVES: The seventh edition of the TNM classification, together with undeniable advantages, has limitations. The International Association for the Study of Lung Cancer (IASLC) Staging Committee has designed an international prospective study to improve this classification. A group of thoracic surgeons and pulmonologists was established in the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) Oncology area, and created a registry of new lung cancer (LC) cases to participate in this project. The aim of this paper is to describe the main characteristics of the patients included. MATERIALS AND METHODS: Prospective, observational, multicentre, multiregional data collection (epidemiological, clinical, therapeutic and, especially, anatomical extension) study, according to the IASLC protocol, to analyse its prognostic value. RESULTS: Two thousand, four hundred and nineteen patients (83.6% men) from 28 hospitals were included. Ninety-six percent of the men and 54% of the women were smokers or ex-smokers. Chest/abdominal computed tomography (CT) scanning was performed in over 90% and positron emission tomography (PET)/CT scanning in 51.5% of cases. Among the 1035 patients who underwent surgery, 77% had early stages (ia to iib), and 61.6% of those treated using other methods had stage iv. Respiratory comorbidity was higher in men (47.9% versus 21.4%). The most common histological subtype was adenocarcinoma (34%), especially in non-smoking women (69.5%). CONCLUSIONS: The proportion of women and adenocarcinomas, as well as those resected at an early stage, increased among LC cases in Spain.

Biopsia pulmonar por videotoracoscopia en el diagnóstico de la enfermedad pulmonar intersticial. Estudio prospectivo y multicéntrico en 224 pacientes / Video-Assisted Thoracoscopic Lung Biopsy in the Diagnosis of Interstitial Lung Disease: A Prospective, Multi-Center Study in 224 Patients

Introducción: Analizar si la localización y el número de biopsias pulmonares obtenidas por videotoracoscopia (BP-VTC) influyen en el diagnóstico de las enfermedades pulmonares intersticiales difusas (EPID) y evaluar la aplicabilidad de un programa de cirugía ambulatoria (CA). Pacientes y método: Estudio prospectivo y multicéntrico de BP-VTC practicadas en pacientes con sospecha de EPID desde enero de 2007 a diciembre de 2009, incluyendo 224 pacientes de 13 centros españoles. Los datos fueron recogidos de manera prospectiva en cada centro y enviados al centro coordinador para su análisis. Resultados: Las zonas más afectadas en la TACAR torácica fueron los lóbulos inferiores (55%). Se llevó a cabo broncoscopia en el 84%, y biopsia transbronquial en el 49,1%. En 179 casos (79,9%) se realizó más de una biopsia (concordancia diagnóstica: 97,2%). Se obtuvo un diagnóstico histopatológico definitivo en 195 pacientes (87%). No se hallaron factores estadísticamente significativos que pudieran predecir un mayor rendimiento diagnóstico (ni la localización anatómica de la biopsia ni el número de ellas). Setenta pacientes (31,3%) fueron incluidos en un programa de CA. Los índices de morbilidad tras el alta fueron comparables entre ingresados (9/154: 5.8%) y ambulatorios (3/70: 4.3%). Conclusiones: La localización anatómica y el número de BP no parecen influir en el diagnóstico de EPID. Los pacientes ambulatorios tuvieron un índice de complicaciones comparable a los casos que ingresaron, por lo cual este procedimiento podría ser incluido en un programa de CA. La BP-CVT es una herramienta fiable y segura para el diagnóstico de los pacientes con sospecha de EPID(AU)

Objectives: To evaluate whether the location and number of lung biopsies obtained by video-assisted thoracoscopy (VAT) influence the diagnosis of diffuse interstitial lung disease (ILD). To assess the applicability of an Ambulatory Surgery Program (ASP). Methods: Prospective, multicenter study of VAT lung biopsies due to suspected ILD from January 2007 to December 2009, including 224 patients from 13 Spanish centers (mean age 57.1 years; 52.6% females). Data were prospectively collected in every institution and sent to the coordination center for analysis. Results: The most affected areas in high resolution chest CT were the lower lobes (55%). Bronchoscopy was performed in 84% and transbronchial biopsy in 49.1%. In 179 cases (79.9%), more than one biopsy was performed, with a diagnostic agreement of 97.2%. A definitive histopathologic diagnosis was obtained in 195 patients (87%). Idiopathic pulmonary fibrosis was the most frequent diagnosis (26%). There were no statistically significant factors that could predict a greater diagnostic yield (neither anatomical location nor number of biopsies). Seventy patients (31.3%) were included in an ASP. After discharge, there were complications in 12 patients (5.4%), similar between patients admitted postoperatively (9/154: 5.8%) and those included in an ASP (3/70: 4.3%). Conclusions: Anatomical location and number of lung biopsy specimens did not seem to influence the diagnosis. The patients included in an ASP had a complication rate comparable to that of the hospitalized, so this procedure can be included in a surgical outpatient program. Lung biopsy obtained by VAT is a powerful and safe tool for diagnosis of suspected ILD, resulting in a definitive diagnosis for the majority of patients with a low morbidity rate(AU)
