Systemic Inflammation after Uniport, Multiport, or Hybrid VATS Lobectomy for Lung Cancer.

BACKGROUND: Different video-assisted thoracic surgery (VATS) approaches can be adopted to perform lobectomy for non-small cell lung cancer. Given the hypothetical link existing between postoperative inflammation and long-term outcomes, we compared the dynamics of systemic inflammation markers after VATS lobectomy performed with uniportal access (UNIVATS), multiportal access (MVATS), or hybrid approach (minimally invasive hybrid open surgery, MIHOS). METHODS: Peripheral blood-derived inflammation markers (neutrophil-to-lymphocyte [NTL] ratio, platelet-to-lymphocyte [PTL] ratio, and systemic immune-inflammation index [SII]) were measured preoperatively and until postoperative day 5 in 109 patients undergoing UNIVATS, MVATS, or MIHOS lobectomy. Differences were compared through repeated-measure analysis of variance, before and after 1:1:1 propensity score matching. Time-to-event analysis was also done by measuring time to NTL normalization, based on the reliability change index for each patient. RESULTS: After UNIVATS, there was a faster decrease in NTL ratio (p = 0.015) and SII (p = 0.019) compared with other approaches. MVATS exhibited more pronounced PTL rebound (p = 0.011). However, all these differences disappeared in matched analysis. After MIHOS, NTL ratio normalization took longer (mean difference: 0.7 ± 0.2 days, p = 0.047), yet MIHOS was not independently associated with slower normalization at Cox's regression analysis (p = 0.255, odds ratio: 1.6, confidence interval: 0.7-4.0). Furthermore, surgical access was not associated with cumulative postoperative morbidity, nor was it with incidence of postoperative pneumonia. CONCLUSION: In this study, different VATS approaches resulted into unsubstantial differences in postoperative systemic inflammatory response, after adjusting for confounders. The majority of patients returned back to preoperative values by postoperative day 5 independently on the adopted surgical access. Further studies are needed to elaborate whether these small differences may still be relevant to patient management.

An Analysis of Respiration with the Smart Sensor SENSIRIB in Patients Undergoing Thoracic Surgery.

The paper examines the problem of respiration monitoring with easily wearable instrumentation by using a smart device that is properly designed and implemented with small and light components. The practical implementation is presented both in practical aspects and from experimental results by following a properly defined method with a medical-like protocol and specific procedure of testing. The results of a statistically significant campaign of experimental tests are reported with the characteristic data from the angles and acceleration components of a sensed rib both to validate the smart device and the procedure for respiration monitoring.

A thymic hyperplasia-related reversible complete atrioventricular block: When compression is more important than compressor.

A 19-year-old patient presented for syncope with third-degree AV block (TDAVB) at ECG. A chest-CT showed a thymic mass that could be responsible for TDAVB due to extrinsic vagal nerve compression. Thymectomy led to complete AV block resolution. An extrinsic vagal compression mechanism should be considered among causes of complete atrioventricular block.

Immunological and Inflammatory Impact of Non-Intubated Lung Metastasectomy.

BACKGROUND: We hypothesized that video-assisted thoracic surgery (VATS) lung metastasectomy under non-intubated anesthesia may have a lesser immunological and inflammatory impact than the same procedure under general anesthesia. METHODS: Between December 2005 and October 2015, 55 patients with pulmonary oligometastases (at the first episode) successfully underwent VATS metastasectomy under non-intubated anesthesia. Lymphocytes subpopulation and interleukins 6 and 10 were measured at different intervals and matched with a control group composed of 13 patients with similar clinical features who refused non-intubated surgery. RESULTS: The non-intubated group demonstrated a lesser reduction of natural killer lymphocytes at 7 days from the procedure (p = 0.04) compared to control. Furthermore, the group revealed a lesser spillage of interleukin 6 after 1 (p = 0.03), 7 (p = 0.04), and 14 (p = 0.05) days. There was no mortality in any groups. Major morbidity rate was significantly higher in the general anesthesia group 3 (5%) vs. 3 (23%) (p = 0.04). The median hospital stay was 3.0 vs. 3.7 (p = 0.033) days, the estimated costs with the non-intubated procedure was significantly lower, even excluding the hospital stay. CONCLUSIONS: VATS lung metastasectomy in non-intubated anesthesia had significantly lesser impact on both immunological and inflammatory response compared to traditional procedure in intubated general anesthesia.

1000 cases of tubeless video-assisted thoracic surgery at the Rome Tor Vergata University.

In the early 2000s, the 'Awake Thoracic Surgery Research Group' at Tor Vergata University began a program of thoracic operations in awake nonintubated patients. To our knowledge this was the first program created with this specific purpose. Since then over 1000 tubeless operations have been carried out successfully, making this series one of the widest in the world. Both nononcologic and oncologic conditions were successively approached and major operations for lung cancer are now being performed. Uniportal access was progressively adopted with significant positive outcomes in postoperative recovery, patient acceptance and economical costs. Failure rates due to patient's intolerance and open surgery conversion are progressively reducing. Tubeless thoracic surgery can be accomplished in a safe manner with effective results.

Multi-reoperations for lung metastases.

In this study, we investigated role and results of multi-reoperations for lung metastases. From 1986 to 2010, 113 consecutive patients (61 men and 52 women; mean age: 53.2 ± 12.8 years) underwent repeated lung metastasectomy with curative intent in our institution. Two procedures were performed in 113 patients, three in 54, four in 31, five in eight and six in three. There was no perioperative mortality. Cumulative 5-year survival was 65% and this was significantly higher than the value recorded for patients undergoing only one metastasectomy (42%; p = 0.021). Size, number of resections and probability of recurrence increased by number of operation whereas disease free interval reduced. At any metastasectomy both short disease-free interval and multiple metastases resulted in the most significant negative prognosticators. In conclusion, redo metastasectomy is worthwhile for the initial procedures, afterwards both disease-free and overall survivals decrease and surgery lose its efficacy.

Video-assisted thoracoscopic thymectomy surgery: Tor Vergata experience.

The therapeutic effect of thymectomy on myasthenia gravis is not completely understood. Several types of thymectomy varying in approach and extent have been performed. None of these disclosed a neat superiority over others. Patients desire thymectomy through small, painless, and cosmetically favorable operations. Video-assisted thoracoscopic surgery (VATS) thymectomy fits all these requests as well as that of the surgeon. Indeed, this approach allows for ample operative space, easy maneuverability, and extended thymectomy. No mortality, low morbidity, faster recovery, short hospital stay, and small economical costs are undoubtedly advantages of VATS over transsternal and transcervical thymectomy. In the near future, the introduction of robotic devices will lead to a new era in the surgery of the thymus. Herein we analyzed our comprehensive experience.

Ultrasound for Intra-Operative Detection of Peri-Centimetric Pulmonary Nodules in Uniportal Video-Assisted Thoracic Surgery (VATS): A Comparison with Conventional Techniques in Multiportal VATS.

Background: Video-assisted thoracic surgery (VATS) has become the gold-standard approach for lung resections. Given the impossibility of digital palpation, we witnessed the progressive development of peri-centimetric and deeply located pulmonary nodule alternative detection techniques. Intra-operative lung ultrasound is an increasingly effective diagnostic method, although only a few small studies have evaluated its accuracy. This study analyzed the effectiveness and sensitivity of uniportal VATS with intra-operative lung ultrasound (ILU), in comparison to multiportal VATS, for visualizing solitary and deep-sited pulmonary nodules. Methods: Patient data from October 2021 to October 2023, from a single center, were retrospectively gathered and analyzed. In total, 31 patients who received ILU-aided uniportal VATS (Group A) were matched for localization time, operative time, sensitivity, and post-operative complications, with 33 undergoing nodule detection with conventional techniques, such as manual or instrumental palpation, in multiportal VATS (Group B). Surgeries were carried out by the same team and ILU was performed by a certified operator. Results: Group A presented a significantly shorter time for nodule detection [median (IQR): 9 (8-10) vs. 14 (12.5-15) min; p < 0.001] and operative time [median (IQR): 33 (29-38) vs. 43 (39-47) min; p < 0.001]. All nodules were correctly localized and resected in Group A (sensitivity 100%), while three were missed in Group B (sensitivity 90.9%). Two patients in Group B presented with a prolonged air leak that was conservatively managed, compared to none in Group A, resulting in a post-operative morbidity rate of 6.1% vs. 0% (p = 0.16). Conclusions: ILU-aided uniportal VATS was faster and more effective than conventional techniques in multiportal VATS for nodule detection.

A numerical analysis of ventilation motion after chest surgery with a RESPIRholter device.

This case report presents a numerical evaluation of respiration in terms of biomechanical parameters of chest motion. This experimental evaluation is performed with RESPIRholter, a wearable device specifically developed to monitor the movement in the ribcage through the motion of the sixth rib whose characteristic motion is considered as representative of the motion of the thorax. Here we present test results acquired with a RESPIRholter device in a 6-h acquisition. These results characterize respiration biomechanics for diagnostic purposes in a chest surgery patient, highlighting the diagnostic utility of RESPIRholter in the identification of post-operation respiratory problem.

Incidence and impact of involuntary rib fracture after intercostal spreading for thoracotomy.

Thoracotomy with rib spreading still remains the preferred approach for complex surgery. Rib fracture is considered a frequent involuntary event during this approach, but its real incidence has not been adequately investigated yet. In this study, we evaluated the incidence of rib fracture after thoracotomy, the possible risk factors and the relationship with post-operative pain and complications. We retrospectively analyzed the medical records of single-institution patients submitted to lateral thoracotomy from January 2016 to June 2023. Exclusion criteria were traumatic etiology and a medical history of osteoporosis. The presence of rib fracture was retrieved by surgical reports or post-operative chest X-ray. Basal and evoked pain after surgery was assessed by Visual Analogue Scale. The considered 30-day post-operative complications were atelectasis, need of endoscopic broncho-aspiration, pneumonia and pleural effusion. A total of 367 consecutive patients underwent thoracotomy in the study period. The median age was 68 (interquartile range 60-75) years. Rib fracture was detected in 179/367 (48.8%) patients. Incidence did not significantly vary throughout years (p = 0.98). The risk of developing post-thoracotomy rib fractures was significantly associated with age greater than the median value (p = 0.003). The presence of rib fracture was related to significantly more elevated evoked pain at 48 h after surgery (p = 0.039) and a higher incidence of complications (32/179 vs 20/188; p = 0.047). Our study demonstrated that rib fracture occurs in almost half of the thoracotomies. Older patients are more likely to develop this event, which significantly correlates to increased evoked post-operative pain and higher rate of post-operative complications.

Ergonomic Assessment of Robotic versus Thoracoscopic Thymectomy.

Introduction: Robotic and thoracoscopic surgery are being increasingly adopted as minimally invasive alternatives to open sternotomy for complete thymectomy. The superior maneuverability range and three-dimensional magnified vision are potential ergonomical advantages of robotic surgery. To compare the ergonomic characteristics of robotic versus thoracoscopic thymectomy, a previously developed scoring system based on impartial findings was employed. The relationship between ergonomic scores and perioperative endpoints was also analyzed. Methods: Perioperative data of patients undergoing robotic or thoracoscopic complete thymectomy between January 2014 and December 2022 at three institutions were retrospectively retrieved. Surgical procedures were divided into four standardized surgical steps: lower-horns, upper-horns, thymic veins and peri-thymic fat dissection. Three ergonomic domains including maneuverability, exposure and instrumentation were scored as excellent(score-3), satisfactory(score-2) and unsatisfactory(score-1) by three independent reviewers. Propensity score matching (2:1) was performed, including anterior mediastinal tumors only. The primary endpoint was the total maneuverability score. Secondary endpoints included the other ergonomic domain scores, intraoperative adverse events, conversion to sternotomy, operative time, post-operative complications and residual disease. Results: A total of 68 robotic and 34 thoracoscopic thymectomies were included after propensity score matching. The robotic group had a higher total maneuverability score (p = 0.039), particularly in the peri-thymic fat dissection (p = 0.003) and peri-thymic fat exposure score (p = 0.027). Moreover, the robotic group had lower intraoperative adverse events (p = 0.02). No differences were found in residual disease. Conclusions: Robotic thymectomy has shown better ergonomic maneuverability compared to thoracoscopy, leading to fewer intraoperative adverse events and comparable early oncological results.

Prognostic significance of uncertain resection for metastasis in the highest mediastinal lymph node after surgery for clinical N0 non-small cell lung cancer.

Background: The International Association for the Study of Lung Cancer defined types of surgical resection and considered the positivity of the highest mediastinal lymph node resected a parameter of "uncertain resection" (R-u). We investigated the metastases in the highest mediastinal lymph node, defined as the lowest numerically numbered station among those resected. We aimed to evaluate the prognostic value of R-u compared with R0. Materials and methods: We selected 550 patients with non-small cell lung cancer at clinical Stage I, IIA, IIB (T3N0M0), or IIIA (T4N0M0) undergoing lobectomy and systematic lymphadenectomy between 2015 and 2020. The R-u group included patients with positive highest mediastinal resected lymph node. Results: In the groups of patients with mediastinal lymph node metastasis, we defined 31 as R-u (45.6%, 31/68). The incidence of metastases in the highest lymph node was related to the pN2 subgroups (p < 0.001) and the type of lymphadenectomy performed (p < 0.001). The survival analysis compared R0 and R-u: 3-year disease-free survival was 69.0% and 20.0%, respectively, and 3-year overall survival was 78.0% and 40.0%, respectively. The recurrence rate was 29.7% in R0 and 71.0% in R-u (p-value < 0.001), and the mortality rate was 18.9% and 51.6%, respectively (p-value < 0.001). R-u variable showed a tendency to be a significant prognostic factor for disease-free survival and overall survival (hazard ratio: 4.6 and 4.5, respectively, p-value < 0.001). Conclusions: The presence of metastasis in the highest mediastinal lymph node removed seems to be an independent prognostic factor for mortality and recurrence. The finding of these metastases represents the margin of cancer dissemination at the time of surgery, so it could imply metastasis into the N3 node or distant metastasis.

The effectiveness of chest T-tube drainage in uniportal video-assisted thoracic surgery.

OBJECTIVES: Uniportal incision located at 4th or 5th intercostal space represents a problem for the correct drainage of distal areas of pleural cavity. The T-shaped tube can drain both the extremities of pleural space. In this study, we evaluated the effectiveness of T-chest tube compared to classic chest tube after uniportal video-assisted thoracic surgery. METHODS: We compared the effectiveness of T-tube and classic 28 CH chest drainage after different surgical procedures in uniportal video-assisted thoracic surgery: lobectomies, wedge resections and pleural and mediastinal biopsies. As primary end points, drained effusion and evidence of pneumothorax at postoperative day 1, subcutaneous emphysema, tube kinking, obstruction and necessity of repositioning or postoperative thoracentesis were considered. Pain at 6 and 24 h after surgery, pain at tube removal and mean hospitalization were analysed as secondary end points. RESULTS: A total of 109 patients were selected for the study, 51 included to the T-tube group while the other 58 ones to the control group with classic drainage. Patients with T-tube showed a significantly lower rate of pneumothorax (29.4% vs 63.8%; P < 0.001), tube kinking (5.9% vs 27.6%; P = 0.003) and need of repositioning (2.0% vs 12.1%; P = 0.043). No significant results were obtained in subcutaneous emphysema (P = 0.26), tube obstruction (P = 0.32), drained effusion (P = 0.11) and need of postoperative thoracentesis (P = 0.18). Patients with T-tube complained of <6 h after surgery (P < 0.001). Conversely, T-tube removal was reported to be more painful (P < 0.001). CONCLUSIONS: Chest T-tube can achieve significantly lower rate of postoperative pneumothorax, kinking and repositioning with less pain 6 hours after surgery compared to classic tube.

Non-Lobe Specific Metastases in Occult N2 after Lobectomy for Clinical N0 Non-Small Cell Lung Cancer.

OBJECTIVES: Non-small cell lung cancer can spread into lobe specific stations and non-lobe-specific mediastinal lymph nodes. We evaluated frequency and features of non-lobe specific nodal metastases, focusing especially on the prognostic value of only non-lobe specific N2-metastases after lobectomy. METHODS: We performed a retrospective review of 550 patients with non-small cell lung cancer with clinical N0, undergoing lobectomy and systematic or lobe specific node dissection. We evaluated disease free and overall survival rates using Kaplan-Meier method and significance was tested by log-rank test. RESULT: Occult N2 disease was detected in 68 patients (8.1%), 26 of them (38.2%) had metastases in non-lobe specific stations. Comparing patients with lobe and non-lobe specific lymph node metastases, 3-years DFS rate was 44.4% vs. 20.0% (p-value = 0.009), while 3-years OS rate was 87.3% vs. 26.7% (p-value <0.001). Among patients with non-lobe specific metastases 16 of them (61.5%) had only non-lobe specific metastases, the remaining 10 patients (38.5%) had metastatic lymph node at the same time in non-lobe specific station but also in lobe-specific stations. Comparing post-operative survival between patients with only non-lobe specific metastases and synchronous lobe and non-lobe specific metastases, 3-years DFS rate was 12.5% vs. 41.3% respectively (p-value = 0.03), and 3-years OS rate was 12.5% vs 76.7% (p-value = 0.002). CONCLUSION: In patients with occult N2 disease, the finding of a metastatic lymph node in a non-lobe specific station relates with significant lower survival rate. The subset of patients who presented only non-lobe specific node metastases showed a significant lower survival rate compared to the remaining occult N2.

Image-guided techniques for localization of pulmonary nodules during video-assisted thoracoscopic surgery lobectomy.

In the modern era when screening and early surveillance of pulmonary nodules are increasing in importance, the management of the pulmonary nodule represents a different challenge to thoracic surgeons. The difficulty lies in the merging of sound surgical and oncological principles with more minimally invasive and appropriate lung-sparing surgery. The success rates of video-assisted thoracoscopic surgery (VATS) resection for smaller as well as subsolid nodules have increased as a result of radiologists' preoperative localization tools. Fast tracking in thoracic surgery is promoted by proper postoperative care for patients having lobectomies in combination with the VATS technique. Image-guided surgery refers to the application of a real-time correlation of the surgical field to preoperative imaging data collection that reflects the precise placement of a chosen surgical instrument in the adjacent anatomic structures. Among the cross-sectional digital imaging techniques the most widely utilized imaging modalities for image-guided therapy are computed tomography and magnetic resonance imaging. Additionally, surgical navigation devices, tracking tools, integration software, ultrasound, and angiography are used to support these procedures. For people who are thinking about implementing or optimizing a nodule localization program in view of workflow patterns, surgeon preferences, and institutional resources in a certain facility, this review provides in-depth, unbiased evaluation and offers useful information.

Blood-Derived Systemic Inflammation Markers and Risk of Nodal Failure in Stage Ia Non-Small Cell Lung Cancer: A Multicentric Study.

BACKGROUND: Unexpected spread to regional lymph nodes can be found in up to 10% of patients with early stage non-small cell lung cancer (NSCLC), thereby affecting both prognosis and treatment. Given the known relation between systemic inflammation and tumor progression, we sought to evaluate whether blood-derived systemic inflammation markers might help to the predict nodal outcome in patients with stage Ia NSCLC. METHODS: Preoperative levels of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammation score (SII, platelets × NLR) were collected from 368 patients who underwent curative lung resection for NSCLC. After categorization, inflammatory markers were subjected to logistic regression and time-event analysis in order to find associations with occult nodal spread and postoperative nodal recurrence. RESULTS: No inflammation marker was associated with the risk of occult nodal spread. SII showed a marginal effect on early nodal recurrence at a quasi-significant level (p = 0.065). However, patients with T1c tumors and elevated PLR and/or SII had significantly shorter times to nodal recurrence compared to T1a/T1b patients (p = 0.001), while patients with T1c and normal PLR/SII did not (p = 0.128). CONCLUSIONS: blood-derived inflammation markers had no value in the preoperative prediction of nodal status. Nevertheless, our results might suggest a modulating effect of platelet-derived inflammation markers on nodal progression after the resection of tumors larger than 2 cm.

Multimodal evaluation of locoregional anaesthesia efficacy on postoperative pain after robotic pulmonary lobectomy for NSCLC: a pilot study.

The primary objectives of the study were to analyse the robotic approach and ultrasound-guided paravertebral block compared to thoracoscopic intercostal nerve block after robotic pulmonary lobectomy on postoperative pain and opioids use. The secondary objectives were to analyse and compare patients' necessity of additional antalgic drugs and patients' performance during respiratory therapy, following robotic surgery and in the two groups. Consecutively, 52 patients undergoing robotic pulmonary lobectomies were treated either with ropivacaine-based intercostal nerve block or paravertebral block from February 2022 to October 2022. When necessary, morphine was administered at day 1. Acetaminophen was administered as an additional antalgic drug on demand up to 3 g per day. Pain was measured 1 h after the end of the surgical procedure and daily through the pain numeric rating scale (NRS). Morphine administration rate and per day and total additional administrations of acetaminophen were recorded. Pain and opioids administration was measured 1 month after the procedure. Data were analysed in the overall population and in the intercostal nerve block group VS paravertebral block group. Overall, 34.6% of the patients required morphine administration and 51.7% of the patients required at least daily acetaminophen administration up to discharge. At 1 month postoperatively, four patients presented with chronic pain and one still was under opioid medication. At intergroup analysis, the paravertebral block group demonstrated lower NRS at fixed time points (p < 0.0001) and lower morphine consumption (45.7%VS11.8%; p = 0.02). Acetaminophen rescue administration at fixed time points was lower in the paravertebral block group (p < 0.0001) and mobility and dynamic pain resulted in better results (p = 0.03; p = 0.04). At 1 month, no differences were found between study groups. Similarly to other minimally invasive techniques, postoperative pain may arise after robotic pulmonary lobectomy. Paravertebral bloc can help to reduce postoperative pain as well as morphine and antalgic drugs administration and improve early mobilization.

Analysis of predictive factors of unforeseen nodal metastases in resected clinical stage I NSCLC.

Background: Despite notable advances made in preoperative staging, unexpected nodal metastases after surgery are still significantly detected. In this study we aim to analyze the upstaging rate in patients with clinical stage I NSCLC without evidence of nodal disease in the preoperative staging who underwent lobectomy and radical lymphadenectomy. Methods: Patients who underwent lobectomy and systematic lymphadenectomy for clinical stage I NSCLC were evaluated. Exclusion criteria included the neoadjuvant treatment, incomplete resection and no adherence to preoperative guidelines. Results: A total of 297 patients were included in the study. 159 patients were female, and the median age was 68 (61 - 73). The variables that showed a significant correlation with the upstaging rate at the univariate analysis were the number of resected lymph nodes and micropapillar/solid adenocar-cinoma subtype. This result was confirmed in the multivariate analysis with a OR= 2.545 (95%CI 1.136-5.701; p=0.02) for the number of resected lymph nodes and a OR=2.717 (95%CI 1.256-5.875; p=0.01) for the high-grade pattern of adenocarcinoma. Conclusion: Our results showed that in a homogeneous cohort of patients with clinical stage I NSCLC, the number of resected lymph nodes and the histological subtype of adenocarcinoma can significantly be associated with nodal metastasis.

Clinical impact of extrapleural pneumonectomy for malignant pleural mesothelioma.

BACKGROUND: The clinical impact of extrapleural pneumonectomy in malignant pleural mesothelioma is poorly investigated. METHODS: Between 1997 and 2007, 29 consecutive patients underwent extrapleural pneumonectomy for mesothelioma and adjuvant chemoradiotherapy. Function (spirometry, arterial blood gas analysis, 6-min walk test, and echocardiographic fraction ejection estimation), symptoms (quantification of pain, dyspnea, cough, fever, weight loss, and Karnofsky performance status) and quality of life [Medical Outcomes Study Short Form, 36 item (SF-36) and St. George's Respiratory Questionnaire] were timely evaluated. Data were prospectively collected and retrospectively reviewed. RESULTS: Only one postoperative death occurred. 30-day postoperative morbidity was 41%. Median survival was 19.5 months with 17 patients still alive at 1 year and 10 at 2 years, respectively. At 3 months, the expected decrement of forced expiratory volume in 1 s (P = 0.06) and forced vital capacity (P = 0.09) was not significant. Conversely, arterial blood gas, 6-min walk test, cardiac fraction ejection, pain (P < 0.05), dyspnea (P < 0.01), cough (P < 0.05), fever (P < 0.01), weight loss (P < 0.01), performance status (P < 0.01), SF-36 physical (P < 0.01), SF-36 mental (P < 0.05), St. George's Respiratory Questionnaire symptom (P < 0.01), activity (P < 0.05), and impact on mood (P < 0.05) improved. At 12 months, the amelioration of pain, dyspnea, performance status, and physical-related quality of life parameters remained stable. Thereafter, all parameters progressively deteriorated, although pain and dyspnea still persisted above the baseline values even after 24 months in all survivors. Postoperative improvement of pain (P = 0.04), dyspnea (P = 0.04), 6-min walk test (P = 0.03), and SF-36 physical (P = 0.04) and mental (P = 0.03) components were positive prognosticators. CONCLUSIONS: Extrapleural pneumonectomy has a significant and durable impact on function and symptoms as well as on physical and mental components of quality of life in patients with malignant pleural mesothelioma.
