Impact of radiological follow-up frequency on resected lung cancer: a propensity score matching analysis.

Background: Despite advances in lung cancer treatment and the subsequent improvement in oncological outcomes, the optimal frequency of radiological follow-up remains unclear. Current recommendations lack consensus and do not consider individual patient characteristics and tumor factors. This study aimed to examine the impact of radiological follow-up frequency on oncological outcomes following lung cancer resection.

Comparison of 5-Year Survival and Disease Recurrence After Trisegmentectomy or Left Upper Lobectomy: A Propensity Score Analysis of the National GEVATS Database.

Introduction: Trisegmentectomy, or resection of the upper subdivision of the left upper lobe with preservation of the lingula, is considered by some authors to be equivalent to right upper lobectomy with middle lobe preservation. Our objective was to compare survival and recurrence after trisegmentectomy versus left upper lobectomy procedures registered in the Spanish Video-Assisted Thoracic Surgery group (GEVATS) database.

Methods: We compared mortality, survival and recurrence in patients with left upper lobectomy or trisegmentectomy after propensity score matching for the following variables: age, smoking habit, tumor size, histologic type, radiological density of tumor, surgical access, forced expiratory volume in one second, diffusing capacity of the lungs for carbon monoxide, hypertension, chronic heart failure, ischemic heart disease, arrhythmia, stroke, peripheral vascular disease, diabetes and pre-surgery nodal status by positron emission tomography/computed tomography.

Presurgical invasive mediastinal staging in lung cancer, unexpected N2 and long-term survival: a registry-based study with data from the Spanish group for video-assisted thoracic surgery.

Background: Mediastinal lymph node staging is a key element in the diagnosis of lung cancer. The combination of computed tomography (CT) and positron emission tomography (PET) has improved staging but some circumstances are known to influence their negative predictive value. The objective of this study was to assess the impact on survival of avoiding invasive mediastinal staging in surgical lung cancer patients with negative mediastinum in CT and PET and intermediate risk of unexpected pN2.

Pathological N1/N2 in Clinical Stage I Bronchogenic Carcinoma. Analysis From a Prospective Multicentre Database.

Objectives: To determine the incidence of occult N1/N2 nodal metastases and associated risk factors in patients with non-small cell lung cancer no larger than 3cm and deemed cN0 by CT and PET-CT in a prospective, multicentre national database.

Methods: Patients with a NSCLC no larger than 3cm, deemed cN0 by PET-CT and CT scan, who had undergone at least a lobectomy, were selected from a national multicentre database of 3533 patients who had undergone anatomic lung resection between 2016 and 2018. Clinical and pathological variables of patients with pN0 and patients with pN1/N2 were compared to identify factors associated with the presence of lymph node metastases.

Thoracoscopic segmentectomy versus lobectomy: A propensity score-matched analysis.

Objectives: The aim of this study is to compare the postoperative complications, perioperative course, and survival among patients from the multicentric Spanish Video-assisted Thoracic Surgery Group database who received video-assisted thoracic surgery lobectomy or video-assisted thoracic surgery anatomic segmentectomy.

Methods: From December 2016 to March 2018, a total of 2250 patients were collected from 33 centers. Overall analysis (video-assisted thoracic surgery lobectomy = 2070; video-assisted thoracic surgery anatomic segmentectomy = 180) and propensity score-matched adjusted analysis (video-assisted thoracic surgery lobectomy = 97; video-assisted thoracic surgery anatomic segmentectomy = 97) were performed to compare postoperative results.

VATS lobectomy morbidity and mortality is lower in patients with the same ppoDLCO: Analysis of the database of the Spanish Video-Assisted Thoracic Surgery Group.

Introduction: Measuring predicted post-operative diffusion capacity of the lung for carbon monoxide (ppoDLCO) is essential to determine patient operability and to stratify the risk of patients who are candidates for major lung cancer surgery. Studies that established surgical risk variables were based on open surgery series. The aim of our study was to analyze morbidity and mortality as a function of ppoDLCO and to compare its behavior in open and video-assisted thoracic surgery (VATS).

External validation of the European Society of Thoracic Surgeons morbidity and mortality risk models.

Objectives: There is a wide variety of predictive models of postoperative risk, although some of them are specific to thoracic surgery, none of them is widely used. The European Society for Thoracic Surgery has recently updated its models of cardiopulmonary morbidity (Eurolung 1) and 30-day mortality (Eurolung 2) after anatomic lung resection. The aim of our work is to carry out the external validation of both models in a multicentre national database.

National evaluation of risk factors for unplanned readmission after lung resection.

Objectives: Unplanned readmission is defined as the return to inpatient hospitalization within 30 days after discharge. Worldwide, its incidence after lung resection ranges between 8% and 50%, and it has been shown to impact both patient recovery and healthcare resources. Our goal was to identify the risk factors to prioritize early follow-ups.

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.

International expert consensus on the management of bleeding during VATS lung surgery.

Intraoperative bleeding is the most crucial safety concern of video-assisted thoracic surgery (VATS) for a major pulmonary resection. Despite the advances in surgical techniques and devices, intraoperative bleeding is still not rare and remains the most common and potentially fatal cause of conversion from VATS to open thoracotomy. Therefore, to guide the clinical practice of VATS lung surgery, we proposed the International Interest Group on Bleeding during VATS Lung Surgery with 65 experts from 10 countries in the field to develop this consensus document.

Background: Patients with pulmonary metastases from colorectal cancer (CRC) may benefit from aggressive surgical therapy. The objective of this study was to determine the role of major anatomic resection for pulmonary metastasectomy to improve survival when compared with limited pulmonary resection.

Patients And Methods: Data of 522 patients (64.

Causal Model of Survival After Pulmonary Metastasectomy of Colorectal Cancer: A Nationwide Prospective Registry.

Background: Although numerous existing studies have analyzed the prognostic factors of patients who have had surgical intervention for lung metastases of colorectal carcinoma (CRC), many of the results obtained until now have been contradictory. As a consequence, there is no established consensus about which group of prognostic factors could have a greater value when considered together.

Methods: This was a multicenter prospective cohort study that included all patients who underwent a first pulmonary metastasectomy of CRC, with radical intent, during a 2-year period (March 2008 to February 2010).

Agreement Between Computed Tomography and Pathologic Nodule Counts in Colorectal Lung Metastases.

Background: Computed tomography is the most common technique used to estimate the number of pulmonary metastases and their resectability. A lack of agreement between radiologic and surgical pathologic findings could potentially lead to incomplete resection or to rejection of patients for potentially curative treatments. The objective of this study was to estimate the disagreement between the number of radiologic lesions and the number of histologically confirmed malignant lesions excised from patients with pulmonary metastases from colorectal cancer.

Impact of inappropriate lymphadenectomy on lung metastasectomy for patients with metastatic colorectal cancer.

Purpose: To evaluate the characteristics of lymph node assessment in the Spanish Colorectal Metastasectomy Registry (GECMP-CCR) and to analyze and compare the survival of patients with pathological absence or presence of lymph node metastases (LNM) with the survival of those with uncertain lymph node status (uLNs).

Methods: A total of 522 patients with lung metastases from colorectal carcinoma were prospectively registered from 2008 to 2010. To confirm the pathologic absence of LNM, systematic nodal dissection or systematic sampling was required, or the lymph node status was coded as uncertain.
