Comparison of Lung Cancer Surgery Outcomes in Queensland for Indigenous and Nonindigenous Australians.

Introduction: Indigenous Australians (Aboriginal and Torres Strait Islander) have lower overall survival from lung cancer compared with nonindigenous Australians. Indigenous Australians receive higher rates of chemotherapy and/or radiotherapy. The equity of peri-operative care and thoracic surgical outcomes in Australian indigenous populations have not been contemporarily evaluated. Methods: We performed a retrospective registry analysis of the Queensland Cardiac Outcomes Registry Thoracic Database evaluating all adult lung cancer resections across Queensland from January 1, 2016 to April 20, 2022. Evaluating the time from diagnosis to surgery, operative data, and postoperative morbidity and mortality comparing Aboriginal and/or Torres Strait Islander people with nonindigenous Australians. Results: There were 31 patients (2.56%) of 1208 who identified as indigenous. The mean age at surgery was 68.2 years versus 66 years in the indigenous and nonindigenous, respectively (p = 0.23). There was female predominance among indigenous patients (n = 28, 90.32%, p < 0.01) and the average body mass index was lower (22.52 versus 27.09, p < 0.01). There was no variation in the surgical parameters or histopathologic distribution of cancer type between groups. Multivariable logistic regression analysis suggested that indigenous patients were at elevated risk of blood transfusion (relative risk 3.9, p = 0.014, OR = 9.01, 95% confidence interval [CI]: 2.25-36.33, p < 0.01) and had greater transfusion requirements (risk ratio 4.08, p = 0.0116 and OR = 12.67, 95% CI: 2.25-71.49, p < 0.01); however, the influence of low absolute number of transfusions must be acknowledged here. Indigenous status was not associated with increased intensive care unit admission (OR = 1.79, 95% CI: 0.17-18.80, p = 0.62), return to operating theater (OR = 2.1, 95% CI: 0.24-18.15, p = 0.50), new atrial fibrillation (OR = 0.52, 95% CI: 0.07-4.01, p = 0.55), prolonged air leak (OR = 0.29, 95% CI: 0.04- 2.16, p = 0.228), or pneumonia postoperatively (OR = 4.77, 95% CI: 0.55-41.71, p = 0.16). With only three deaths, no meaningful trends were observed. Time from diagnosis to surgery was comparable in the indigenous and nonindigenous groups (88.6 d, 95% CI: 54.26-123.24 versus 86.2 d, 81.40-91.02, p = 0.87). Postoperative length of stay was not numerically or statistically different between groups. (indigenous 7.54 d versus nonindigenous 7.13 d, p = 0.90). Conclusions: Indigenous patients are more likely to receive a blood transfusion than nonindigenous patients during lung resection. Reassuringly, the perioperative care provided to indigenous Australians undergoing lung resection in Queensland seems to be comparable to that of the nonindigenous population.

The influence of the COVID-19 pandemic on lung cancer surgery in Queensland.

BACKGROUND: The coronavirus disease-19 (COVID-19) pandemic poses unprecedented challenges to global healthcare. The contemporary influence of COVID-19 on the delivery of lung cancer surgery has not been examined in Queensland. METHODS: We performed a retrospective registry analysis of the Queensland Cardiac Outcomes Registry (QCOR), thoracic database examining all adult lung cancer resections across Queensland from 1/1/2016 to 30/4/2022. We compared the data prior to, and after, the introduction of COVID-restrictions. RESULTS: There were 1207 patients. Mean age at surgery was 66 years and 1115 (92%) lobectomies were performed. We demonstrated a significant delay from time of diagnosis to surgery from 80 to 96 days (P < 0.0005), after introducing COVID-restrictions. The number of surgeries performed per month decreased after the pandemic and has not recovered (P = 0.012). 2022 saw a sharp reduction in cases with 49 surgeries, compared to 71 in 2019 for the same period. CONCLUSION: Restrictions were associated with a significant increase in pathological upstaging, greatest immediately after the introduction of COVID-restrictions (IRR 1.71, CI 0.93-2.94, P = 0.05). COVID-19 delayed the access to surgery, reduced surgical capacity and consequently resulted in pathological upstaging throughout Queensland.

Thoracic Surgery and the Elderly; Is Lobectomy Safe in Octogenarians?

PURPOSE: Non-small cell lung cancer is the most common malignancy of the elderly, with 5-year survival estimates of 16.8%. The prognostic benefit of surgical resection for early lung cancer is irrefutable and maintained irrespective of age, even in patients over 75 years. Concerningly, despite the prognostic benefit of surgery there are deviations from standard treatment protocols with increasing age due to concerns of increased morbidity and mortality with surgery, without evidence to support this. METHOD: A state-wide retrospective registry study of Queensland's Cardiac Outcomes Registry's (QCOR) Thoracic Database examining the influence of age on the safety of Lung Resection (1 January 2016-20 April 2022). RESULTS: This included 1,232 patients, mean age at surgery was 66 years (range 14-91 years), with 918 thoracotomies performed. Three deaths occurred within 30-days (0.24%). Octogenarians (n=60) had lower rates of smoking (26% vs 6%), respiratory, cardiovascular, and cerebrovascular disease suggesting this subset of patients is carefully selected. Octogenarian status was not associated with an increased all-cause morbidity (p=0.09) or 30-day mortality (p=0.06). Further to this it was not associated with re-operation (4.4% vs 8.3%, p=0.1), increased postoperative stay (6.66 vs 6.65 days, p=0.99) or myocardial infarction. An independent predictor of morbidity was male sex (OR 1.58, CI 1.2-2.1 p=0.001). CONCLUSION: Age ≥80 years did not increase surgical morbidity or mortality in the appropriately selected patient and should not be a barrier to referral for consideration of surgical resection.

Delayed Tracheoesophageal Fistula and Refractory Respiratory Failure Caused by Inhalation Burns and Emergency Venovenous ECMO to Facilitate Its Management: A Case Report.

Acquired tracheoesophageal fistulae are uncommon in burn patients but can occur as a complication of inhalation injury. We report a case of a 30-yr-old male patient presenting after suffering from inhalation and 25% total body surface area burns. On postburns day 14, he developed a massive tracheoesophageal fistula causing refractory acute respiratory failure. Veno-venous extracorporeal membrane (VV ECMO) oxygenation was initiated without systemic anticoagulation via bi-femoral cannulation under transthoracic echocardiography guidance. He underwent successful 5-hr apnoeic ventilation-assisted surgical repair of the fistula via a right posterolateral thoracotomy. ECMO was discontinued after 36 hr, and he was discharged to the ward after 33 d in the intensive care unit. Inhalation burn injury can cause a delayed life-threatening tracheoesophageal fistula. Surgical repair can be successfully performed for this condition. VV- ECMO can be used to facilitate prolonged apnoeic surgery and to manage refractory respiratory failure due to this condition.

Metastatic lipoblastoma-like tumour.

INTRODUCTION: Lipoblastoma-like tumours (LLT) are uncommon and their biologic nature is not well-understood. Complete resection of the primary lesion is usually curative. This is the first reported case of metastatic LLT. CASE PRESENTATION AND MANAGEMENT: This patient originally had a large primary resected from the vulva. She subsequently developed tumours in multiple areas including her right pleura and lung. These were resected and pathology was consistent with LLT. On follow-up imaging, there was evidence of metastatic disease. CONCLUSION: The patient is currently undergoing detailed molecular analysis in the hope of detecting a molecular target. Given the infrequent occurrence of LLT, its behaviour is not well understood. Longer duration of follow up is required and prognostic markers need to be identified to better direct treatment.

Development of an Australia and New Zealand Lung Cancer Clinical Quality Registry: a protocol paper.

INTRODUCTION: Lung cancer is the leading cause of cancer mortality, comprising the largest national cancer disease burden in Australia and New Zealand. Regional reports identify substantial evidence-practice gaps, unwarranted variation from best practice, and variation in processes and outcomes of care between treating centres. The Australia and New Zealand Lung Cancer Registry (ANZLCR) will be developed as a Clinical Quality Registry to monitor the safety, quality and effectiveness of lung cancer care in Australia and New Zealand. METHODS AND ANALYSIS: Patient participants will include all adults >18 years of age with a new diagnosis of non-small-cell lung cancer (NSCLC), SCLC, thymoma or mesothelioma. The ANZLCR will register confirmed diagnoses using opt-out consent. Data will address key patient, disease, management processes and outcomes reported as clinical quality indicators. Electronic data collection facilitated by local data collectors and local, state and federal data linkage will enhance completeness and accuracy. Data will be stored and maintained in a secure web-based data platform overseen by registry management. Central governance with binational representation from consumers, patients and carers, governance, administration, health department, health policy bodies, university research and healthcare workers will provide project oversight. ETHICS AND DISSEMINATION: The ANZLCR has received national ethics approval under the National Mutual Acceptance scheme. Data will be routinely reported to participating sites describing performance against measures of agreed best practice and nationally to stakeholders including federal, state and territory departments of health. Local, regional and (bi)national benchmarks, augmented with online dashboard indicator reporting will enable local targeting of quality improvement efforts.

Australasian Malignant PLeural Effusion (AMPLE)-3 trial: study protocol for a multi-centre randomised study comparing indwelling pleural catheter (±talc pleurodesis) versus video-assisted thoracoscopic surgery for management of malignant pleural effusion.

INTRODUCTION: Malignant pleural effusions (MPEs) are common. MPE causes significant breathlessness and impairs quality of life. Indwelling pleural catheters (IPC) allow ambulatory drainage and reduce hospital days and re-intervention rates when compared to standard talc slurry pleurodesis. Daily drainage accelerates pleurodesis, and talc instillation via the IPC has been proven feasible and safe. Surgical pleurodesis via video-assisted thoracoscopic surgery (VATS) is considered a one-off intervention for MPE and is often recommended to patients who are fit for surgery. The AMPLE-3 trial is the first randomised trial to compare IPC (±talc pleurodesis) and VATS pleurodesis in those who are fit for surgery. METHODS AND ANALYSIS: A multi-centre, open-labelled randomised trial of patients with symptomatic MPE, expected survival of ≥ 6 months and good performance status randomised 1:1 to either IPC or VATS pleurodesis. Participant randomisation will be minimised for (i) cancer type (mesothelioma vs non-mesothelioma); (ii) previous pleurodesis (vs not); and (iii) trapped lung, if known (vs not). Primary outcome is the need for further ipsilateral pleural interventions over 12 months or until death, if sooner. Secondary outcomes include days in hospital, quality of life (QoL) measures, physical activity levels, safety profile, health economics, adverse events, and survival. The trial will recruit 158 participants who will be followed up for 12 months. ETHICS AND DISSEMINATION: Sir Charles Gairdner and Osborne Park Health Care Group (HREC) has approved the study (reference: RGS356). Results will be published in peer-reviewed journals and presented at scientific meetings. DISCUSSION: Both IPC and VATS are commonly used procedures for MPE. The AMPLE-3 trial will provide data to help define the merits and shortcomings of these procedures and inform future clinical care algorithms. TRIAL REGISTRATION: Australia New Zealand Clinical Trial Registry ACTRN12618001013257 . Registered on 18 June 2018. PROTOCOL VERSION: Version 3.00/4.02.19.

Validation of the Eighth Edition TNM Lung Cancer Staging System.

INTRODUCTION: We performed a validation study at our institution, the International Union Against Cancer (Union for International Cancer Control latest version of TNM Classification of Malignant Tumors Eighth Edition). METHODS: Data were collected from the Queensland Oncology Online registry of NSCLC or SCLC cases between 2000 and 2015 and validated against the Queensland Integrated Lung Cancer Outcomes Project registry using case identification number, first name, last name, and date of birth. Where data were available, cases were classified according to the Union for International Cancer Control TNM seventh edition stage groupings and then compared with the eighth edition groupings. Kaplan-Meier curves were plotted, and the log-rank test of survival differences was performed with SPSS version 25 (IBM Corp, Armonk, NY). RESULTS: Of the 3636 cases, 3352 and 1031 had complete clinical and pathologic staging, respectively. Median survival time was found to reduce with increasing clinical stage: seventh edition (IA: 88, IB: 44, IIA: 31, IIB: 18, IIIA: 15, IIIB: 8, and IV: 5 mo) versus eighth edition TNM stage (IA1: not reached, IA2: 88, IA3: 53, IB: 56, IIA: 36, IIB: 22, IIIA: 14, IIIB: 9, IIIC: 8, IVA: 6, and IVB: 3 mo). A similar overall pattern was reflected in the pathologic stage: seventh edition (IA: 124, IB: 110, IIA: 48, IIB: 42, IIIA: 26, IIIB: 31, and IV: 27 mo) versus eighth edition (IA1: not reached, IA2: 122, IA3: 125, IB: 144, IIA: 98, IIB: 57, IIIA: 31, IIIB: 24, and IVA: 7 mo). The log-rank test for survival curves was significant at p < 0.001. CONCLUSIONS: Our external validation study confirms the prognostic accuracy of the eighth edition TNM lung cancer classification. Our analyses also indicated that IIIB, IIIC, and IVA stage groups had similar survival outcomes and suggest further research for refinement.

Delayed complications following microwave ablation of lung tumours.

The majority of complications following microwave ablation (MWA) of lung tumours are immediately evident, however, delayed complications do occasionally occur. The radiologist plays a major role in identifying and in guiding the management of these complications. This pictorial essay explores the imaging appejmironce of several potentially life-threatening delayed complications of pulmonary MWA.

First Human Use of a New Robotic-Assisted Fiber Optic Sensing Navigation System for Small Peripheral Pulmonary Nodules.

BACKGROUND: We tested a new, investigational robotic-assisted bronchoscope system with a remotely controlled catheter to access small peripheral bronchi with real-time driving under live visualization and distal tip articulation of the catheter. The unique catheter remains stationary once located at the biopsy position. OBJECTIVES: The primary objectives of this study were to evaluate the safety and feasibility of a new shape-sensing robotic bronchoscope system to bronchoscopically approach and facilitate the sampling of small peripheral pulmonary nodules of 1-3 cm. Secondary objectives included evaluating procedural characteristics and early performance trends associated with the use of the new robotic bronchoscope system. METHODS: Subjects were enrolled according to study eligibility criteria at a single center. Navigation pathways were semi-automatically created using pre-procedure CT scans. Simultaneous (real-time) viewing of actual and virtual bronchi was used real time during navigation to the displayed target. An endobronchial ultrasound mini-probe was used to confirm lesion location. Flexible 19- to 23-G needles specifically designed to accommodate tight bend radii in transbronchial needle aspiration were used along with conventional biopsy tools. Enrolled subjects completed follow-up visits up to 6 months after the procedure. RESULTS: The study included 29 subjects with a mean lesion size of 12.2 ± 4.2, 12.3 ± 3.3, and 11.7 ± 4.1 mm in the axial, coronal, and sagittal planes, respectively. The CT bronchus sign was absent in 41.4% of cases. In 96.6% of cases, the target was reached, and samples were obtained. No device-related adverse events and no instances of pneumothorax or excessive bleeding were observed during the procedure. Early performance trends demonstrated an overall diagnostic yield of 79.3% and a diagnostic yield for malignancy of 88%. CONCLUSION: This new robotic-assisted bronchoscope system safely navigated to very small peripheral airways under continuous visualization, and through maintenance of a static position, it provides a unique sampling capability for the biopsy of small solitary pulmonary nodules.

Catamenial Pneumothorax, a Commonly Misdiagnosed Thoracic Condition: Multicentre Experience and Audit of a Small Case Series With Review of the Literature.

BACKGROUND: Catamenial pneumothorax (CP) is an unusual condition affecting premenopausal women and commonly misdiagnosed as simple pneumothorax. It is characterised by its recurrence between the day before and within 72 hours after the onset of menstruation. It has been associated with thoracic endometriosis but the aetiology is not well understood and there is no unified agreement for its optimal management. The aim of this study is to determine the incidence of CP in surgical patients and the results of their treatment. METHODS: Females between the ages of 30 to 50 years with a diagnosis of pneumothorax, admitted for surgery over a 10-year period in four different hospitals were retrospectively reviewed for evidence of CP. An audit of surgical and medical management of the patients with CP and their short to midterm outcomes was performed in addition to a systemic review of the literature on CP. RESULT: A total of 120 premenopausal female patients with a diagnosis of pneumothorax were admitted for Video Assisted Thoracoscopic (VAT) surgery and five women (4.1%) with a mean age of 42.6 years were diagnosed to have CP through surgical and histological findings. The first case was diagnosed 5 years ago and the last three within recent 12 months after the changes in surgical practices of inspecting diaphragmatic surface in suspected cases of CP. Four patients underwent diaphragmatic plication and one patient had a pleural biopsy. All patients underwent talc pleurodesis and hormone therapy in the postoperative period. Short to midterm (mean follow-up period of 25.2 months) results of the patients with CP were encouraging. CONCLUSIONS: It is possible that many of the cohort of premenopausal female patients presenting with recurrent pneumothorax are misdiagnosed as spontaneous pneumothorax (SP) because routine inspection of the diaphragmatic surface is not often performed. A thorough menstrual history and its temporal relation to pneumothorax onset should be assessed on every woman presenting with recurrent pneumothorax and intraoperative exploration of diaphragmatic surface should be performed in the patients with high suspicion of CP as the patients diagnosed with CP have a good outcome with surgery and hormone therapy.

Risk stratification in the investigation of pulmonary nodules in a high-risk cohort: positron emission tomography/computed tomography outperforms clinical risk prediction algorithms.

BACKGROUND: Clinical prediction models and 18-fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) are used for the assessment of solitary pulmonary nodules (SPN); however, a biopsy is still required before treatment, which carries risk. AIM: To determine the combined predictive benefit of one such model combined with modern PET/CT data to improve decision-making about biopsy prior to treatment and possibly reduce costs. METHODS: Patients with a SPN undergoing 18F-FDG-PET/CT from January 2011 to December 2012 were retrospectively identified; 143 patients met inclusion criteria. PET/CT studies were rated (5-point visual scale), and CT characteristics were determined. Tissue was obtained by endobronchial ultrasonography with guide sheath (EBUS-GS), CT-guided biopsy and/or surgery. EBUS-transbronchial needle aspiration (TBNA) was used instead of nodule biopsy if there were PET-positive sub-centimetre lymph nodes. RESULTS: The prediction model yielded an area under the receiver operating characteristic curve (AUC-ROC) of 64% (95% confidence interval (CI) 0.55-0.75). PET/CT increased this to 75% (95% CI 0.65-0.84). The 11% improvement is statistically significant. PET/CT score was the best single predictor for malignancy. A PET score of 1-2 had a specificity of 100% (CI 0.73-1.0), whereas a score of 4-5 had a sensitivity of only 76% (CI 0.68-0.84). No significant difference in clinical prediction scores between groups was noted. PET/CT showed the greatest benefit in true negatives and in detecting small mediastinal lymph nodes to allow EBUS-TBNA with a higher diagnostic rate. Cost analysis did not support a policy of resection-without-tissue diagnosis. CONCLUSION: PET/CT improves the clinical prediction of SPN, but its greatest use is in proving benignity. High PET scores had high false positive rates and did not add to clinical prediction. PET should be incorporated early in decision-making to allow for more effective biopsy strategies.

Low tumour cell content in a lung tumour bank: implications for molecular characterisation.

Lung cancer encompasses multiple malignant epithelial tumour types, each with specific targetable, potentially actionable mutations, such that precision management mandates accurate tumour typing. Molecular characterisation studies require high tumour cell content and low necrosis content, yet lung cancers are frequently a heterogeneous mixture of tumour and stromal cells. We hypothesised that there may be systematic differences in tumour cell content according to histological subtype, and that this may have implications for tumour banks as a resource for comprehensive molecular characterisation studies in lung cancer. To investigate this, we estimated tumour cell and necrosis content of 4267 samples resected from 752 primary lung tumour specimens contributed to a lung tissue bank. We found that banked lung cancer samples had low tumour cell content (33%) generally, although it was higher in carcinoids (77.5%) than other lung cancer subtypes. Tumour cells comprise a variable and often small component of banked resected tumour samples, and are accompanied by stromal reaction, inflammation, fibrosis, and normal structures. This has implications for the adequacy of unselected tumour bank samples for diagnostic and molecular investigations, and further research is needed to determine whether tumour cell content has a significant impact on analytical results in studies using tissue from tumour bank resources.

Respiratory bronchiolitis-associated interstitial lung disease secondary to electronic nicotine delivery system use confirmed with open lung biopsy.

As a modern phenomenon, there is currently limited understanding of the possible toxic effects and broader implications of electronic nicotine delivery systems (ENDS). Large volumes of aerosolized particles are inhaled during "vaping" and there are now an increasing number of case reports demonstrating toxic effects of ENDS, as well as human studies demonstrating impaired lung function in users. This article presents a case of respiratory bronchiolitis interstitial lung disease (RB-ILD) precipitated by vaping in a 33-year-old male with 10 pack years of traditional cigarette and prior treatment for mixed germ cell tumour. The patient had started vaping 10-15 times per day while continuing to smoke 10 traditional cigarettes per day. After 3 months of exposure to e-cigarette vapour, chest computed tomography demonstrated multiple new poorly defined pulmonary nodules with fluffy parenchyma opacification centred along the terminal bronchovascular units. Video-assisted thoracoscopy with lung biopsy of the right upper and right middle lobes was undertaken. The microscopic findings were overall consistent with RB-ILD. This case demonstrates toxicity with use of ENDS on open lung biopsy with resolution of radiographic findings on cessation. We believe that this is the first case where open lung biopsy has demonstrated this and our findings are consistent with RB-ILD.

Screen-detected subsolid pulmonary nodules: long-term follow-up and application of the PanCan lung cancer risk prediction model.

OBJECTIVE: To report the long-term follow-up of subsolid nodules (SSNs) detected in participants of a prospective low-dose CT lung cancer screening cohort, and to investigate the utility of the PanCan model in stratifying risk in baseline SSNs. METHODS: Participants underwent a baseline scan, two annual incidence scans and further follow-up scans for the detected nodules. All SSNs underwent a minimum of 2 years of follow-up (unless resolved or resected). Risk of malignancy was estimated using the PanCan model; discrimination [area under the receiver-operating characteristic curve (AUC)] and calibration (Hosmer-Lemeshow goodness-of-fit test) were assessed. The Mann-Whitney U-Wilcoxon test was used to compare estimated risk between groups. RESULTS: 70 SSNs were detected in 41 (16.0%) out of 256 total participants. Median follow-up period was 25.5 months (range 2.0-74.0 months). 29 (41.4%) SSNs were transient. Five (7.1%) SSNs were resected, all found to be Stage I lung adenocarcinoma, including one SSN stable in size for 3.0 years before growth was detected. The PanCan model had good discrimination for the 52 baseline SSNs (AUC = 0.89; 95% confidence interval 0.76-1); the Hosmer-Lemeshow goodness-of-fit test was non-significant (p = 0.27). Estimated risk was significantly higher in the baseline SSNs found to be cancer vs those not found to be cancer after 2-6 years of follow-up (p < 0.01). CONCLUSION: Our findings support a long-term follow-up approach for screen-detected SSNs for 3 years or longer. The PanCan model appeared discriminatory and well calibrated in this cohort. ADVANCES IN KNOWLEDGE: The PanCan model may have utility in identifying low-risk SSNs which could be followed with less frequent CT scans.

Patients' and doctors' preferences for adjuvant chemotherapy in resected non-small-cell lung cancer: What makes it worthwhile?

BACKGROUND: Adjuvant chemotherapy (ACT) in non-small-cell lung cancer (NSCLC) improves overall survival, but the benefits must be weighed against its harms. We sought to determine the survival benefits that patients and their doctors judged sufficient to make ACT in NSCLC worthwhile. METHODS: 122 patients completed a self-administered questionnaire at baseline and 6 months (before & after ACT, if they had it); 82 doctors completed the questionnaire once only. The time trade-off method was used to determine the minimum survival benefits judged sufficient in four hypothetical scenarios. Baseline survival times were 3 years & 5 years and baseline survival rates (at 5 years) were 50% & 65%. RESULTS: At baseline, the median benefits judged sufficient by patients were an extra 9 months (Interquartile range (IQR) 1-12 months) beyond 3 years & 5 years and an extra 5% (IQR 0.1-10%) beyond 50% & 65%. At 6 months (n=91), patients' preferences had the same median benefit (9 months & 5%) but varied more (IQRs 0-18 months & 0-15%) than at baseline. Factors associated with judging smaller benefits sufficient were deciding to have ACT (P=0.01, 0.02) and better well-being (P=0.01, 0.006) during ACT. Doctors' preferences, compared with patients' preferences, had similar median benefits (9 months & 5%) but varied less (IQR 6-12 months versus 1-12 months, P<0.001; 5%-10% versus 0.1-10%, P<0.001). CONCLUSION: Most patients and doctors judged moderate survival benefits sufficient to make ACT in NSCLC worthwhile, but the preferences of doctors varied less than those of patients. Doctors should endeavour to elicit patients' preferences during discussions about ACT in NSCLC.

Surgery in 2013 and beyond.

Lung cancer is a leading cause of cancer related mortality. The role of surgery continues to evolve and in the last ten years there have been a number of significant changes in the surgical management of lung cancer. These changes extend across the entire surgical spectrum of lung cancer management including diagnosis, staging, treatment and pathology. Positron Emission Tomography (PET) scanning and ultrasound (EBUS) have redefined traditional staging paradigms, and surgical techniques, including video-assisted thoracoscopy (VATS), robotic surgery and uniportal surgery, are now accepted as standard of care in many centers. The changing pathology of lung cancer, with more peripheral tumours and an increase in adenocarcinomas has important implications for the Thoracic surgeon. Screening, using Low-Dose CT scanning, is having an impact, with not only a higher percentage of lower stage cancers detected, but also redefining the role of sublobar resection. The incidence of pneumonectomy has reduced as have the rates of "exploratory thoracotomy". In general, lung resection is considered for stage I and II patients with a selected role in more advanced stage disease as part of a multimodality approach. This paper will look at these issues and how they impact on Thoracic Surgical practice in 2013 and beyond.
