RESUMEN
BACKGROUND: Malignant pleural mesothelioma incidence continues to rise, with few available evidence-based therapeutic options. Results of previous non-randomised studies suggested that video-assisted thoracoscopic partial pleurectomy (VAT-PP) might improve symptom control and survival. We aimed to compare efficacy in terms of overall survival, and cost, of VAT-PP and talc pleurodesis in patients with malignant pleural mesothelioma. METHODS: We undertook an open-label, parallel-group, randomised, controlled trial in patients aged 18 years or older with any subtype of confirmed or suspected mesothelioma with pleural effusion, recruited from 12 hospitals in the UK. Eligible patients were randomly assigned (1:1) to either VAT-PP or talc pleurodesis by computer-generated random numbers, stratified by European Organisation for Research and Treatment of Cancer risk category (high vs low). The primary outcome was overall survival at 1 year, analysed by intention to treat (all patients randomly assigned to a treatment group with a final diagnosis of mesothelioma). This trial is registered with ClinicalTrials.gov, number NCT00821860. FINDINGS: Between Oct 24, 2003, and Jan 24, 2012, we randomly assigned 196 patients, of whom 175 (88 assigned to talc pleurodesis, 87 assigned to VAT-PP) had confirmed mesothelioma. Overall survival at 1 year was 52% (95% CI 41-62) in the VAT-PP group and 57% (46-66) in the talc pleurodesis group (hazard ratio 1·04 [95% CI 0·76-1·42]; p=0·81). Surgical complications were significantly more common after VAT-PP than after talc pleurodesis, occurring in 24 (31%) of 78 patients who completed VAT-PP versus ten (14%) of 73 patients who completed talc pleurodesis (p=0·019), as were respiratory complications (19 [24%] vs 11 [15%]; p=0·22) and air-leak beyond 10 days (five [6%] vs one [1%]; p=0·21), although not significantly so. Median hospital stay was longer at 7 days (IQR 5-11) in patients who received VAT-PP compared with 3 days (2-5) for those who received talc pleurodesis (p<0·0001). INTERPRETATION: VAT-PP is not recommended to improve overall survival in patients with pleural effusion due to malignant pleural mesothelioma, and talc pleurodesis might be preferable considering the fewer complications and shorter hospital stay associated with this treatment.

BACKGROUND & AIMS: To prospectively assess the nutritional status of patients referred for lung cancer surgery, as well as to assess the prognostic value of nutritional status in determining the surgical outcome. METHODS: One hundred and forty-six patients with potentially operable lung cancer were recruited. Loss of appetite and weight loss were recorded. All patients had serum albumin levels and body mass index (BMI) measured. Surgical outcome were noted. RESULTS: Mean age was 69 (range 42-85) years; 29/146 were not referred for surgery. Eight patients underwent failed thoracotomy. In the remaining 109 patients, mean BMI was 26. Seven patients had BMI of 19 or less. Forty-four patients had ideal body weight. The majority of patients (n=58) were overweight. Mean serum albumin was 37g/l and lower than 30g/l in 5 cases. There were 4% postoperative deaths and 32% with poor surgical outcome. There was no statistical difference in mean BMI, serum albumin, loss of appetite or weight loss between the two outcome groups. CONCLUSION: BMI is usually well preserved in patients with operable lung cancer. There was no association between low BMI, low serum albumin, loss of appetite or weight loss, and postoperative death or poor surgical outcome in this study.

OBJECTIVE: Prospectively to evaluate the effects of lung resection on lung function (as measured via spirometry) and exercise capacity (as measured via shuttle-walk test) in lung cancer patients. METHODS: We conducted pulmonary function tests and the shuttle-walk test with 110 consecutive patients, before and 1 month, 3 months, and 6 months after lobectomy (n = 73) or pneumonectomy (n = 37). All the patients underwent a standard posterolateral thoracotomy. Eighty-eight patients completed all 3 postoperative assessments. RESULTS: At 6 months after resection, the lobectomy patients had lost 15% of their preoperative forced expiratory volume in the first second (FEV1) (p < 0.001) and 16% of their exercise capacity (p < 0.001), and the pneumonectomy patients had lost 35% of their preoperative FEV(1) (p < 0.001) and 23% of their exercise capacity (p < 0.001). CONCLUSIONS: Lobectomy patients suffered significant reduction of functional reserve, with almost equal deterioration between lung function and exercise capacity. Pneumonectomy patients had a more substantial loss of functional reserve, and a disproportionate loss of pulmonary function relative to exercise capacity. Therefore, pulmonary function test values considered in isolation may exaggerate the loss of functional exercise capacity in pneumonectomy patients, which is important because many lung cancer patients who require resection for cure are prepared to accept the risks of immediate surgical complications and mortality, but are unwilling to risk long-term poor exercise capacity.

OBJECTIVE: The American College of Chest Physicians (ACCP) recommends using quantitative perfusion scintigraphy to predict postoperative lung function in lung cancer patients with borderline pulmonary function tests who will undergo pneumonectomy. However, previous scintigraphic data were gathered on small cohorts more than a decade ago, when surgical populations were significantly different with respect to age and sex compared with typical lung cancer patients undergoing pneumonectomy in 2005. We therefore revisited the use of V/Q scintigraphy in pneumonectomy patients in predicting postoperative pulmonary function and the appropriateness of current clinical guidelines. CONCLUSION: Contrary to ACCP guidelines, we found that ventilation scintigraphy alone provided the best correlation between the predicted and actual postoperative values and recommend its use to predict postoperative lung function. However, scintigraphic techniques may underestimate postoperative lung function, so caution is required before unnecessarily preventing a patient from undergoing surgery that offers a potential cure.

STUDY OBJECTIVES: Surgical resection remains the treatment of choice for anatomically resectable non-small cell lung cancer. However, the presence of associated comorbid conditions increases the risk of death and surgical complications. Several studies have evaluated the usefulness of preoperative exercise testing for predicting postoperative morbidity and mortality. The aim of this study was to establish whether exercise testing could predict poor surgical outcome in lung cancer surgery and whether the absolute value or percentage of predicted value is the better predictor of the surgical outcome. DESIGN: The study was designed as a prospective study. PATIENTS AND SETTING: One hundred thirty patients with potentially operable lung cancer at Papworth Hospital over 2 years were recruited; of these, 101 underwent curative surgery. INTERVENTIONS: Spirometry and cardiopulmonary exercise tests were performed for every patient (n = 99), except for two patients with back problems. We also recorded the outcome of surgery, in particular, complications and mortality. MEASUREMENTS AND RESULTS: Mean maximum oxygen transport at peak exercise (Vo(2)peak) was 18.3 mL/kg/min (SD, 4.7 mL/kg/min), and mean percentage of predicted Vo(2)peak value was 84.4% (SD, 30%). Poor surgical outcome was significantly related to Vo(2)peak percentage of predicted (p < 0.01) but not to the actual oxygen uptake value. CONCLUSIONS: The use of the percentage of predicted Vo(2)peak value would be a better indicator of surgical outcome, since it predicts the surgical outcome better, and corrects for normal physiologic ranges. The threshold of Vo(2)peak for surgical intervention could be set between 50% and 60% of predicted without excess surgical mortality.

OBJECTIVE: Wound infections after cardiac surgery carry high morbidity and mortality. A plethora of management strategies have been used to treat such infections. We assessed the impact of vacuum-assisted closure on the management of sternal wound infections in terms of wound healing, duration of vacuum-assisted closure, and cost of treatment. METHODS: Between November 1998 and June 2001, a total of 27 mediastinal infections were managed with vacuum-assisted closure. Group A (n = 14) had vacuum-assisted closure as the final treatment modality, whereas in group B (n = 13) vacuum-assisted closure was followed by either a myocutaneous flap (n = 8) or primary (n = 5) wound closure. The choice of additional treatment modality was based on wound size. RESULTS: In group A, 4 patients died and a satisfactorily healed scar was achieved in 64% of cases. Median durations of vacuum-assisted closure and hospital stay in group A were 13.5 days (interquartile range 8.8-32.2 days) and 20 days (interquartile range 16.7-25.2 days), respectively. Mortality was 7.7% in group B, with a treatment failure rate of 15%. Median duration of vacuum-assisted closure in group B was 8 days (interquartile range 5.5-18 days), and median hospital stay was 29 days (interquartile range 25.8-38.2 days). During the year before institution of vacuum-assisted closure, poststernotomy infection (n = 13) was managed with rewiring and closed irrigation system. Treatment during this year failed in 30.7% of cases (n = 4/13), and mortality was also 30.7%. The total cost (hospitalization and treatment) per patient for vacuum-assisted closure was 16,400 dollars, compared with 20,000 dollars for the closed irrigation system treatment. CONCLUSION: Vacuum-assisted closure, used alone or before other surgical treatment strategies, is an acceptable treatment modality for infections in cardiac surgery with reasonable morbidity, mortality, and cost.

Hand ischemia is a major concern after radial artery harvesting for coronary revascularization. Although a number of preoperative tests have been described to assess the adequacy of ulnar collateral blood flow, many of them are subjective and unreliable. In addition, the presence of arterial connections between the radial and ulnar systems in the elbow and forearm and variability in forearm angiology imply that assessment of alternative blood supply to the hand can only be made once collateral branches of the radial artery have been divided. We describe a technique for intraoperative assessment of ulnar collateral blood flow after mobilization and division of collateral branches of the radial artery.

OBJECTIVES: The role of post-mortem following thoracic surgery has not been previously studied. Most importantly, the clinical diagnosis of thoracic surgical mortality cannot be certain unless post-mortem analysis has been performed. METHODS: Consecutive post-mortem data were collected on 110 patients between 1992 and 2001 (66.3% of all in-hospital thoracic surgical deaths). Clinically attributed causes of death were compared with post-mortem findings. RESULTS: A total of 4302 thoracic operations were performed during the 10-year period, with overall mortality 3.8%. The mean age was 63.6 years (range 21-87) with 73.6% male. In the 110 patients undergoing post-mortem examination, the operations performed were pneumonectomy 24.5%, lobectomy 14.5%, oesophagectomy 12.7%, lung biopsy 8.2%, pleurectomy/bullectomy 6.4%, decortication 4.5%, lung volume reduction 1.8%, other thoracic 13.6%, other oesophageal 9.1%, and other procedures 4.5%. The mean time to death was 12.5 days (range 0-85). The causes of death were respiratory 47.3%, cardiac 16.4%, multiple organ failure 8.2%, sepsis 6.4%, gastrointestinal 4.5%, haemorrhage/technical failure 10%, and others 7.3%. Post-mortem revealed an unsuspected cause of death in 34 (31%) patients, comprising pulmonary 17, cardiac 5, gastrointestinal 3, haemorrhage/technical failure 2, multiple organ failure 2 and other 5. CONCLUSION: Post-mortem determined unsuspected diagnoses in a high proportion of patients undergoing thoracic surgery. Post-mortem continues to be the 'gold standard' method for attributing the cause of death. Accurate outcome data following thoracic surgery are essential for proper audit, and hence for improvements in clinical practice to occur.

OBJECTIVE: Surgery remains the treatment of choice in patients with potentially resectable lung carcinoma. Both the British Thoracic Society and American Chest Physician guidelines for the selection of patients with lung cancer surgery suggest the use of a shuttle walk test to predict outcome in patients with borderline lung function. The guidelines suggest that if the patient is unable to walk 250 m during a shuttle walk test, they are high risk for surgery. However, there is no published evidence to support this recommendation. Therefore, we undertook a prospective study to examine the relationship between shuttle walk test and surgical outcome in 139 patients undergoing assessment for possible lung cancer surgery. METHODS: The shuttle walk test was performed in 139 potentially resectable patients, recruited over a 2 year period, prior to surgery. One hundred and eleven patients underwent surgery. Outcome of surgery, including duration of hospital stay, complication and mortality rates was recorded. Student's t-test was used to compare the shuttle walk distance in patients with good and poor outcome from surgery. RESULTS: Mean age of patients undergoing surgery was 69 years (42-85). Mean shuttle walk distance was 395 m (145-780), with a mean oxygen desaturation of 4% (0-14) during the test. Sixty nine patients had a good surgical outcome and 34 had a poor outcome. The shuttle walk distance was not statistically different in the two outcome groups. CONCLUSION: Shuttle walk distance should not be used to predict poor surgical outcome in lung cancer patients, contrary to current recommendations. It is therefore advisable to perform a formal cardiopulmonary exercise test if at all possible. The usefulness of a shuttle walk test might be improved. It could be compared to a predicted value, as for a formal cardiopulmonary exercise test.

Lung cancer is the most common cause of cancer death with unchanged mortality for 50 years. Only localized nonsmall-cell lung cancer (NSCLC) is curable. In these patients it is essential to accurately predict survival to help identify those that will benefit from treatment and those at risk of relapse. Despite needing this clinical information, prospective data are lacking. We therefore prospectively identified prognostic factors in patients with potentially curable lung cancer. Over 2 years, 110 consecutive patients with confirmed localized NSCLC (stages 1-3A) were recruited from a single tertiary center. Prognostic factors investigated included age, gender, body mass index (BMI), performance status, comorbidity, disease stage, quality of life, and respiratory physiology. Patients were followed up for 3-5 years and mortality recorded. The data were analyzed using survival analysis methods. Twenty-eight patients died within 1 year, 15 patients died within 2 years, and 11 patients died within 3 years postsurgery. Kaplan-Meier survival estimates show a survival rate of 51% at 3 years. Factors significantly (p < 0.05) associated with poor overall survival were age at assessment, diabetes, serum albumin, peak VO(2) max, shuttle walk distance, and predicted postoperative transfer factor. In multiple-variable survival models, the strongest predictors of survival overall were diabetes and shuttle walk distance. The results show that potentially curable lung cancer patients should not be discriminated against with respect to weight and smoking history. Careful attention is required when managing patients with diabetes. Respiratory physiologic measurements were of limited value in predicting long-term survival after lung cancer surgery.

Interstitial pneumonia is well known to increase the risk of lung cancer. We describe a young man who underwent single-lung transplantation for confirmed usual interstitial pneumonia and who was unexpectedly found to have multifocal adenocarcinoma in the explanted lung. Induction immunosuppression therapy was decreased and full screening for further tumor development was undertaken. Post-operatively further consolidative changes developed in the remaining native lung and, after diagnosis and staging, a native pneumonectomy was performed for adenocarcinoma. The good early outcome and management dilemmas are discussed, together with a review of the literature.

We present a case of nephrogenic diabetes insipidus that occurred after on-pump coronary artery bypass grafting in a patient taking long-term lithium carbonate. Lithium toxicity (2.79 mmol/L) was identified on postoperative day 9. Serum sodium peaked at 175 mmol/L on postoperative day 21. Serum osmolality peaked at 384 mOsm/kg H2O, with a urinary osmolality of 403 mOsm/kg H2O. The patient was ultimately managed with hemofiltration and high-dose 1-desamino-8-D-arginine-vasopressin. Recommendations are made based on our experience of this case. In patients on long-term lithium therapy, the potentially life-threatening complication of lithium-induced nephrogenic diabetes insipidus should be specifically anticipated and managed.

Malignant pleural mesothelioma (MPM) is a highly aggressive cancer of the pleura with a well-established male predominance and causative link with asbestos exposure. We report four cases of female patients with MPM referred for palliation of symptoms thought to be due to previous non-pleural malignancy.With emerging novel treatments for MPM, this article discusses four unusual cases of MPM occurring in the setting of other malignancy, highlights the importance of considering a primary diagnosis of MPM even in patients with other malignancy, and reinforces the benefits of video-assisted surgical biopsy which allows simultaneous diagnosis and treatment.

OBJECTIVES: In patients with suspected diffuse interstitial lung disease, open lung biopsy is associated with high mortality (16%). This risk is only acceptable if diagnosis is made and management enhanced. We reviewed the role of VATS techniques in this group to determine the morbidity, mortality and outcomes in terms of diagnosis and enhanced management. METHODS: Over the period of 5 years, 78 patients with suspected diagnosis of diffuse interstitial lung disease on clinical and radiological grounds were referred to a single surgical team. The patients' case notes and histology reports were reviewed retrospectively. Correlation was made with histopathological diagnosis. RESULTS: All 78 patients had sufficient provision of material for histological analysis. Eight patients had a histological diagnosis not consistent with diffuse interstitial lung disease; in all eight patients, this significantly altered the subsequent management. Of the 70 patients with diffuse lung disease, 26 patients (37.1%) had a histological diagnosis of usual interstitial pneumonia. Thirteen patients (18.6%) had a histological diagnosis of unclassifiable diffuse lung disease despite an adequate biopsy. The remaining 31 patients (44.3%) had other positive histological diagnosis made. A difference between pre-operative clinico-radiological and final histological diagnosis sufficient to change prognosis and definitive management was made in 19 patients (27.1%). The mean and median post-operative stay was 2.8 days and 2 days, respectively. The in-hospital mortality was one patient (1.5%) due to adult respiratory distress syndrome. CONCLUSIONS: VATS lung biopsy can be performed in this group of patient with low mortality of 1.5%. It provides sufficient material for histological diagnosis in 100% of patients and alters the management and prognosis in a significant number of patients. We propose that the role of VATS and clinico-radiological techniques should be compared in a prospective controlled clinical trial.

We present 6 cases of the successful use of vacuum-assisted closure dressings as the primary treatment of wound infection after thoracic organ transplantation. In a series of 160 successive transplant operations, deep wound infections developed in 6 patients (3.7%). These all fully resolved over 3 to 29 days with the use of vacuum dressings. We believe vacuum-assisted closure therapy in the context of heart and lung transplantation is effective, well tolerated, and avoids the need for repeated surgical debridement and reconstruction.

BACKGROUND: In patients with non-small cell lung cancer, the only realistic chance of cure is surgical resection. However, in some of these patients there is such poor respiratory reserve that surgery can result in an unacceptable quality of life. In order to identify these patients, various pulmonary function tests and scintigraphic techniques have been used. The current American College of Physicians and British Thoracic Society guidelines do not recommend the use of quantitative ventilation-perfusion scintigraphy to predict postoperative function in lung cancer patients undergoing lobectomy. These guidelines may have been influenced by previous scintigraphic studies performed over a decade ago. Since then there have been advances in both surgical techniques and scintigraphic techniques, and the surgical population has become older and more female represented. METHODS: We prospectively performed spirometry and quantitative ventilation-perfusion scintigraphy on 61 consecutive patients undergoing lobectomy for lung cancer. Spirometry was repeated one-month postsurgery. Both a simple segment counting technique alone and scintigraphy were used to predict the postoperative lung function. RESULTS: There was statistically significant correlation (p < 0.01) between the predicted postoperative lung function using both the simple segment counting technique and the scintigraphic techniques. However, the correlation using simple segment counting was of negligible difference compared to scintigraphy. CONCLUSIONS: In keeping with current American Chest Physician and British Thoracic Society guidelines, our results suggest that quantitative ventilation-perfusion scintigraphy is not necessary in the preoperative assessment of lung cancer patients undergoing lobectomy. The simple segmenting technique can be used to predict postoperative lung function in lobectomy patients.
