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., (Copyright © 2013 SEPAR.

Objective: The objective of this descriptive study was to analyze the current situation and forecast the future requirements for specialists in thoracic surgery, taking into account the number of doctors entering and those possibly leaving this specialty., Material and Methods: The data for this study were taken from the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) (n=304), Thoracic Surgeons' Club (n=122), and the Spanish Council of Medical Associations (n=225). We also took into account the current number of resident surgeons (n=84). Other specialists were included who are not recorded in these databases but who are known to be practicing (n=10). The total number of practicing specialists obtained was 211., Results: There are currently 52 working thoracic surgery departments and the highest number of practicing specialists was recorded in Madrid (n=44), Catalonia (n=33), and Andalusia (n=33). The forecast number of retirements (at age 65 years) and incorporations of new specialists means that there will be a surplus of 57 thoracic surgeons in the next 5 years., Conclusions: Thoracic surgery needs to limit the intake of new trainee specialists for at least the next 5 years.

Postpneumonectomy syndrome is a rare complication of pneumonectomy that develops as a result of excessive displacement of mediastinal structures into the empty cavity. We report the case of a 72-year-old man who developed dysphagia and progressive weakness, along with signs of hypotension due to low cardiac output, following removal of the left lung for lung cancer. Intubation and transfer to the intensive care unit was necessary. When such causes as pulmonary embolism, pneumonia and COPD exacerbation had been ruled out, postpneumonectomy syndrome was diagnosed. Two tissue expansion prostheses (100 mL and 400 mL) were implanted surgically to keep the mediastinum in position and reverse symptoms immediately. We conclude that postpneumonectomy syndrome after left pneumonectomy is a rare complication that may be more frequent than the literature suggests, given that signs may be masked by a diagnosis of cardiogenic shock that leads to death. Surgical repair is simple, reversing symptoms immediately.

This paper analyzes the influence of perioperative transfusion on survival after lung cancer surgery. Between January 1991 and December 1995, we enrolled 405 patients, 196 of whom received transfusions and 209 of whom did not. Follow-up extended to December 1997. Excluded were patients undergoing exploratory thoracotomy (n = 92), those who died during the postoperative period (n = 19) and those lost to follow-up (n = 13). The final number of patients in the study was 281 (136 who received transfusions and 145 who did not). We analyzed age, sex, general clinical status measured on the Eastern Cooperative Oncology Group (ECOG) scale, histological type and TNM staging. Single and multiple variable analyses were performed. At the end of the study 158 patients were alive and 123 had died. Transfusions were used more often in pneumonectomies (p < 0.001) and in patients with an ECOG score of 2 (p < 0.01). Survival at 36 and 60 months, calculated using the Kaplan-Meier method was 52% and 30%, respectively, for those who had received transfusions, and 53% and 49%, respectively, for those who had not. The differences were not statistically significant (p > 0.1). Multivariant analysis failed to demonstrate an influence of transfusion on survival (relative risk of 1.08; 95% confidence interval 0.72-1.61; p > 0.1). We conclude that there is no negative prognostic effect of perioperative transfusion.

Recognizing the confirmed efficacy of urokinase as a thrombolytic and proteolytic agent, we assess its usefulness in the treatment of multiloculated pleural effusion, empyema and hematoma as a substitute of other more invasive procedures. Treatment with urokinase was applied in 18 consecutive cases. Inclusion criteria were a well-placed thoracic probe that did not drain and a radiological image showing occupation. Patients were excluded if they had bronchial fistulas or hemothorax of less than 7 days duration. Effusion in the included cases had developed after pneumonia, after surgery or after trauma. Treatment lasted 3 to 4 days ant was considered effective or not based on the volume of liquid drained and on radiological evidence of change. The amount of liquid drained was highly variable (mean 1,282 and S.D. 1,224; range 100-3,975). Radiological change was considered completely satisfactory in 10 cases, with 6 patients continuing to show occupation of the costophrenic sinus with no clinical repercussions. Two patients died of causes unrelated to administration of the drug. There were two mild relapses that did not require a second round of treatment with urokinase. Patients were followed for a least 30 days after discharge and no new recurrences were detected. We have found urokinase to be a useful fibrinolytic agent for treating multiloculated effusion. Contraindications are few and therefore urokinase should be considered the first-choice treatment to be applied before other more invasive measures are taken.

Three cases are reported of bronchopleural fistula successfully resolved by using biological adhesives through the intrabronchial way. In the three cases the rigid bronchoscope was used to prepare the field and the passage of the adhesive material. The results obtained allow the consideration of this procedure as useful for small fistulas and as a initial therapeutical approach for other fistulas due to the small morbidity rate associated with this procedure compared with others.
