Does age over 80 years have to be a contraindication for lung cancer surgery—a nationwide database study

2018

IF 1.804 (2017); International audience; Background: Nowadays surgery remains the best treatment for localized lung cancer (LC). However, patients over 80 years old are often denied surgery because of the postoperative risk of death. This study aimed to estimate in-hospital mortality (IHM) and determine whether age over 80 is the most important predictor of IHM after LC surgery.Methods: From January 2005 to December 2015, 97,440 patients, including 4,438 patients over 80 years old, were operated on for LC and recorded in the French Administrative Database. Characteristics of patients, hospitals and surgery were analysed.Results: Crude IHM was 3.73% (n=3,639) and 7.77% (n=345) for the over 8…

Is an activity volume threshold really realistic for lung cancer resection?

2018

IF 1.804 (2017); International audience; Background:We analyzed volume as a continuous variable to estimate threshold, which is a methodology rarely seen in the literature. The objective of this work was to assess hospital volume for lung cancer (LC) surgery and to establish the associated threshold for acceptable in-hospital mortality (IHM). Data was obtained from the French national medico-administrative database.Methods:From January 2005 to December 2016, data from 108,571 patients operated for LC in France were collected from the national administrative database. To estimate the volume threshold, hierarchical logistic regression models were developed.Results:The crude IHM rate was 5.2% …

Validation and update of the thoracic surgery scoring system (Thoracoscore) risk model.

2020

Abstract OBJECTIVES The performance of prediction models tends to deteriorate over time. The purpose of this study was to update the Thoracoscore risk prediction model with recent data from the Epithor nationwide thoracic surgery database. METHODS From January 2016 to December 2017, a total of 56 279 patients were operated on for mediastinal, pleural, chest wall or lung disease. We used 3 recommended methods to update the Thoracoscore prediction model and then proceeded to develop a new risk model. Thirty-day hospital mortality included patients who died within the first 30 days of the operation and those who died later during the same hospital stay. RESULTS We compared the baseline patient…

Impact of video-assisted thoracic surgery approach on postoperative mortality after lobectomy in octogenarians.

2019

The number of octogenarians who present with localized lung cancer eligible for surgical resection is increasing. Video-assisted thoracic surgery lobectomy has been widely accepted, but the potential benefit in octogenarians is not well established, especially for postoperative mortality. This study aimed to assess the impact of a video-assisted thoracic surgery approach on postoperative mortality after lobectomy for lung cancer in octogenarians.From January 2005 to December 2016, all patients aged more than 80 years who received lobectomy treatment for lung cancer were retrieved from the French Administrative Database. The end point was 30-day postoperative death. A propensity score was ge…

Comparison of Epithor clinical national database and medico-administrative database to identify the influence of case-mix on the estimation of hospit…

2019

BackgroundThe national Epithor database was initiated in 2003 in France. Fifteen years on, a quality assessment of the recorded data seemed necessary. This study examines the completeness of the data recorded in Epithor through a comparison with the French PMSI database, which is the national medico-administrative reference database. The aim of this study was to demonstrate the influence of data quality with respect to identifying 30-day mortality hospital outliers.MethodsWe used each hospital's individual FINESS code to compare the number of pulmonary resections and deaths recorded in Epithor to the figures found in the PMSI. Centers were classified into either the good-quality data (GQD) …

In-hospital mortality following lung cancer resection: nationwide administrative database.

2016

Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the “Plan Cancer”) according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005–2007, 2008–2010 and 2011–2013.Global crude IHM was 3.9%: 4.3% during 2005–2007, 4% during 2008–2010 and 3.5% during 2011–2013 (p<0.01). 296, 259 and 209 centres p…
